RESUMO

The mono- and divalent spacer cation investigation in sodium/indium-based 2D double perovskites revealed significant impacts on optoelectronic properties due to distortions in the inorganic layers. The strong electron-phonon coupling in a novel lead-free Dion-Jacobson phase highlights a promising class for broad-emission devices based on self-trapped excitons (STE), offering enhanced structural stability.

RESUMO

The lack of synthesized information regarding biodiversity is a major problem among researchers, leading to a pervasive cycle where ecologists make field campaigns to collect information that already exists and yet has not been made available for a broader audience. This problem leads to long-lasting effects in public policies such as spending money multiple times to conduct similar studies in the same area. We aim to identify this knowledge gap by synthesizing information available regarding two Brazilian long-term biodiversity programs and the metadata generated by them. Using a unique dataset containing 1904 metadata, we identified patterns of metadata distribution and intensity of research conducted in Brazil, as well as where we should concentrate research efforts in the next decades. We found that the majority of metadata were about vertebrates, followed by plants, invertebrates, and fungi. Caatinga was the biome with least metadata, and that there's still a lack of information regarding all biomes in Brazil, with none of them being sufficiently sampled. We hope that these results will have implications for broader conservation and management guiding, as well as to funding allocation programs.

RESUMO

An often-overlooked question of the biodiversity crisis is how natural hazards contribute to species extinction risk. To address this issue, we explored how four natural hazards, earthquakes, hurricanes, tsunamis, and volcanoes, overlapped with the distribution ranges of amphibians, birds, mammals, and reptiles that have either narrow distributions or populations with few mature individuals. To assess which species are at risk from these natural hazards, we combined the frequency and magnitude of each natural hazard to estimate their impact. We considered species at risk if they overlapped with regions where any of the four natural hazards historically occurred (n = 3,722). Those species with at least a quarter of their range subjected to a high relative impact were considered at high risk (n = 2,001) of extinction due to natural hazards. In total, 834 reptiles, 617 amphibians, 302 birds, and 248 mammals were at high risk and they were mainly distributed on islands and in the tropics. Hurricanes (n = 983) and earthquakes (n = 868) affected most species, while tsunamis (n = 272), and volcanoes (n = 171) affected considerably fewer. The region with the highest number of species at high risk was the Pacific Ring of Fire, especially due to volcanoes, earthquakes, and tsunamis, while hurricane-related high-risk species were concentrated in the Caribbean Sea, Gulf of Mexico, and northwestern Pacific Ocean. Our study provides important information regarding the species at risk due to natural hazards and can help guide conservation attention and efforts to safeguard their survival.

RESUMO

Liraglutide (LIRA) is a glucagon-like peptide-1 (GLP-1) receptor agonist renowned for its efficacy in treating type 2 diabetes mellitus (T2DM) and is typically administered via subcutaneous injections. Oral delivery, although more desirable for being painless and potentially enhancing patient adherence, is challenged by the peptide's low bioavailability and vulnerability to digestive enzymes. This study aimed to develop LIRA-containing zein-based nanoparticles stabilized with eudragit RS100 and chitosan for oral use (Z-ERS-CS/LIRA). These nanoparticles demonstrated a spherical shape, with a mean diameter of 238.6 nm, a polydispersity index of 0.099, a zeta potential of +40.9 mV, and an encapsulation efficiency of 41%. In vitro release studies indicated a prolonged release, with up to 61% of LIRA released over 24 h. Notably, the nanoparticles showed considerable resistance and stability in simulated gastric and intestinal fluids, suggesting protection from pH and enzymatic degradation. Pharmacokinetic analysis revealed that orally administered Z-ERS-CS/LIRA paralleled the pharmacokinetic profile seen with subcutaneously delivered LIRA. Furthermore, in vivo tests on a diabetic rat model showed that Z-ERS-CS/LIRA significantly controlled glucose levels, comparable to the results observed with free LIRA. The findings underscore Z-ERS-CS/LIRA nanoparticles as a promising approach for oral LIRA delivery in T2DM management.

RESUMO

The present study describes the immature stages of Opoptera syme (Hübner, [1821]) using SEM and Micro-CT to generate 2D and 3D models to study the morphology and chaetotaxy, and present information on the natural history, behavior, and population biology. In laboratory, eggs were laid singly, and the isolated larvae passed through six to seven instars. Host plant in the study site is unknown, but larvae are known to feed on bamboos; in laboratory, larvae accepted the ornamental bamboo Bambusa textilis McClure, 1940. Adults are diurnal and univoltine, flying from December to April (the austral summer). The present study adds information to the biology and natural history of Brassolini, an iconic and still poorly known tribe of Neotropical butterflies.

RESUMO

Butterfly eyespots are wing patterns reminiscent of vertebrate eyes, formed by concentric rings of contrastingly coloured scales. Eyespots are usually located close to the wing margin and often regarded as the single most conspicuous pattern element of butterfly wing colour displays. Recent efforts to understand the processes involved in the formation of eyespots have been driven mainly by evo-devo approaches focused on model species. However, patterns of change implied by phylogenetic relationships can also inform hypotheses about the underlying developmental mechanisms associated with the formation or disappearance of eyespots, and the limits of phenotypic diversity occurring in nature. Here we present a combined evidence phylogenetic hypothesis for the genus Eunica, a prominent member of diverse Neotropical butterfly communities, that features notable variation among species in eyespot patterns on the ventral hind wing surface. The data matrix consists of one mitochondrial gene region (COI), four nuclear gene regions (GAPDH, RPS5, EF1a and Wingless) and 68 morphological characters. A combined cladistic analysis with all the characters concatenated produced a single most parsimonious tree that, although fully resolved, includes many nodes with modest branch support. The phylogenetic hypothesis presented corroborates a previously proposed morphological trend leading to the loss of eyespots, together with an increase in the size of the conserved eyespots, relative to outgroup taxa. Furthermore, wing colour pattern dimorphism and the presence of androconia suggest that the most remarkable instances of sexual dimorphism are present in the species of Eunica with the most derived eyespot patterns, and are in most cases accompanied by autapomorphic combinations of scent scales and "hair pencils". We discuss natural and sexual selection as potential adaptive explanations for dorsal and ventral wing patterns.

RESUMO

OBJECTIVE: To evaluate the effect of prolonged (P) polymerization time of a universal adhesive system applied in etch-and-rinse (ER) or self-etch (SE) strategies on the clinical performance of restorations in non-carious cervical lesions (NCCLs), after 36 months of clinical service. METHODS: A total of 140 restorations were randomly placed in 35 subjects according to the polymerization time groups: ER (10 s); ER-P (40 s); SE (10 s); and SE-P (40 s) at 1,200 mW/cm2. Composite resin was placed incrementally. The restorations were evaluated immediately and after 6, 12, 18, and 36 months using the FDI criteria. Data were analyzed using the Kaplan-Meier survival test for retention loss, and the Kruskal-Wallis' test for secondary outcomes (α = 0.05). RESULTS: After 36 months, 19 restorations were lost: ER 6, ER-P 2, SE 9, SE-P 2. The retention rates were 82.3% for ER; 94.1 % for ER-P; 73.5 % for SE; and 94.1 % for SE-P, with a significant difference between ER vs. ER-P and SE vs. SE-P, as well as ER vs. SE-P and ER-P vs. SE (p < 0.0001). Minor defects were observed in 18 restorations for the marginal staining criteria: ER 5, ER-P 2, SE 8, SE-P 3; and in 33 restorations for the marginal adaptation criteria: ER 11, ER-P 4, SE 12, and SE-P 6 (p > 0.05). No restorations showed recurrence of caries or postoperative sensitivity. CONCLUSIONS: A prolonged polymerization time of 40 s improves the clinical performance of the universal adhesive for both adhesive strategies evaluated, even after 36 months. CLINICAL SIGNIFICANCE: Prolonging the polymerization time of a universal adhesive from 10 to 40 s has been shown to improve its clinical performance when used in NCCLs.

RESUMO

Despite the considerable morbidity and mortality of yellow fever virus (YFV) infections in Brazil, our understanding of disease outbreaks is hampered by limited viral genomic data. Here, through a combination of phylogenetic and epidemiological models, we reconstructed the recent transmission history of YFV within different epidemic seasons in Brazil. A suitability index based on the highly domesticated Aedes aegypti was able to capture the seasonality of reported human infections. Spatial modeling revealed spatial hotspots with both past reporting and low vaccination coverage, which coincided with many of the largest urban centers in the Southeast. Phylodynamic analysis unraveled the circulation of three distinct lineages and provided proof of the directionality of a known spatial corridor that connects the endemic North with the extra-Amazonian basin. This study illustrates that genomics linked with eco-epidemiology can provide new insights into the landscape of YFV transmission, augmenting traditional approaches to infectious disease surveillance and control.

RESUMO

X-ray micro-computed tomography imaging (micro-CT) is valuable for systematic research since it permits the non-destructive scanning and imaging of internal structures of very rare species and/or type specimens. Additionally, micro-CT allows to view the morphology and the functional anatomy of structures in their natural anatomical position, without deformations that typically occur using classical dissection protocols. In this study we provide the description of two new species of lichen moths (Lepidoptera: Erebidae, Lithosiini) from the Atlantic Forest in eastern Brazil: Nodozana heliae Moraes sp. nov. from Rio de Janeiro state and Epeiromulona pataxo Moraes & Aguiar sp. nov. from Bahia state. The male and female genitalia as well as the wing morphology were examined by means of non-destructive micro-CT, subsequent 3D model reconstruction, 360 degree spinning animations, 2D images from different angles, and those were compared against classical genitalia dissections from the same specimens. We conclude that techniques complement each other, micro-CT being particularly useful to study wing venation, sclerotized internal structures and muscles, while classical dissection is useful to study membranous structures, particularly in the female genitalia, abdominal skin and specialised scales on the male 8th sternite.

RESUMO

Chikungunya (CHIK) is a re-emerging viral infection endemic in tropical and subtropical areas. While the typical clinical presentation is an acute febrile syndrome, long-term articular complications and even death can occur. This review characterizes the global epidemiological and economic burden of chikungunya. The search included studies published from 2007 to 2022 in MEDLINE, Embase, LILACS, and SciELO for a thorough evaluation of the literature. Rayyan software was used for data analysis, and data were summarized descriptively and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Seventy-six publications were included. Chikungunya is widely distributed in the tropics, including Africa, Asia, South America, and Oceania/the Pacific Islands, and co-circulates with other simultaneous arboviruses such as DENV, ZIKV, and YFV. Chikungunya infection can lead to chronic articular manifestations with a significant impact on the quality of life in the long term. In addition, it generates absenteeism and economic and social losses and can cause fatal infections in vulnerable populations, mainly in high-risk patients with co-morbidities and at the extremes of age. Reported costs associated with CHIKV diseases are substantial and vary by region, age group, and public/private delivery of healthcare services. The chikungunya disease burden includes chronicity, severe infections, increased hospitalization risks, and associated mortality. The disease can impact the economy in several spheres, significantly affecting the health system and national economies. Understanding and measuring the full impact of this re-emerging disease is essential.

RESUMO

The biology, immature stages, geographic distribution, and systematic position of Glennia pylotis (Godart, 1819) are presented. This species is mostly restricted to the southeastern coastal Atlantic Forest, from the States of São Paulo to Bahia, with sparse records in the interior of Brazil, Argentina, and Bolivia (this locality is most probably spurious-see below). Data on immature stages are based on textual descriptions; pupal skins were illustrated and compared with those of other members of the subtribe Pierina. Based on molecular data, G. pylotis was recovered as a member of the "Leptophobia clade," as the sister group of all other genera in this clade except for Leptophobia. The immature stages are similar to, and host plants are the same, of several other related genera within Pierina, especially the "Leptophobia clade." By compiling all available data, searching for unpublished information in museums (including the finding of empty pupal cases) and adding molecular evidence for G. pylotis, not only its systematic position was elucidated, but its true conservation status could also be assessed.

RESUMO

Stability and maintenance of the crystal structure are the main drawbacks of the application of organic-inorganic perovskites in photovoltaic devices. The ΔT = 62 K robust shift of the structural phase transition observed here allows us to conduct a comprehensive study at room temperature of the tetragonal versus cubic phase on MAPbI3. The absence of the shift in the cubic transition for all-inorganic CsPbI3 samples confirms the importance of both orientation and dynamics of the organic cations. Our results provide a unique opportunity to evaluate the physical properties of both cubic and tetragonal phases of MAPbI3 at the same temperature, eliminating different phonon effects as possible causes for different properties. Besides higher electrical resistivity, the perovskite cubic phase presents a faster charge carrier lifetime than the tetragonal phase and partial PL quenching, pointing toward increased trap-assisted nonradiative recombination. The light absorption coefficient in the cubic phase is larger than the absorption in the tetragonal phase in the green region.

RESUMO

Trata-se de estudo quanti-qualitativo que analisa o retorno das atividades presenciais nos cursos de Odontologia brasileiros, durante a pandemia de COVID-19, e as dificuldades enfrentadas, comparando instituições públicas e privadas. Um formulário on-line com questões abertas e fechadas foi encaminhado por e-mail aos representantes dos cursos de Odontologia, de março a junho de 2021. Foram incluídos os cursos cadastrados no sitee-MEC iniciados até 2017. A análise quantitativa utilizou os testes qui-quadrado, exato de Fisher e t de Student(p<0,05); uma questão aberta foi submetida à análise temática de conteúdo. Dos 329 cursos elegíveis, foram respondidos 83 formulários (21 públicos e 62 privados). Os cursos de instituições públicas apresentaram menor frequência de retorno das atividades presenciais até a data da coleta (p=0,038), inclusive com maior proporção de suspensão das atividades clínicas e laboratoriais (p≤0,001), mas sem diferença para aulas teóricas remotas (p>0,05). Os cursos privados demonstraram ter maior disponibilidade de recursos para o retorno presencial, tais como: estrutura, funcionários e docentes (p<0,001). Apesar das normas de biossegurança constituírem um desafio comum, as principais dificuldades relatadas nas instituições privadas diante do retorno das atividades presenciais foram a modulação ou escalonamento das turmas e ambientes de aula, controle do fluxo de pessoas e implantação de protocolos. Nas públicas, destacam-se dificuldades relacionadas à adequação da estrutura e aquisição de materiais. Conclui-se que a maioria dos cursos de Odontologia havia retomado às aulas no início de 2021, mas as instituições privadas apresentaram maior proporção de retorno às atividades laboratoriais e clínicas presenciais (AU).

This is a quantitative-qualitative study analyzing the return of on-site activities in Brazilian dentistry undergraduate courses during the COVID-19 pandemic and the difficulties faced, comparing public and private institutions. An online form with open and multiple-choice questions was sent via e-mail to the representatives of dentistry courses from March to June 2021. The courses included were those registered on the e-MEC webpage that had started up to 2017. The quantitative analysis employed the chi-square, the Fisher exact, and the T student tests (p<0.05); the open question was subjected to thematic content analysis. Out of the 329 eligible courses, 83 forms were answered and returned (21 public and 62 private). Public institution courses showed lower frequency of return to on-site activities up tothe data collection (p=0.038), and presented higher proportion of suspension of clinical and laboratory activities (p≤0.001), but no difference regarding remote theoretical lessons (p>0.05). Private courses showed higher availability of resources supporting the return to on-site activities, namely, structure, workers, and professors (p<0.001). Although biosafety norms presented a common challenge, the main difficulties reported in private institutions related to the return to on-site activities were the modulation and schedule of the classes and lesson environments, controlling the flow of people, and the implementation of protocols. Public institutions highlighted difficulties related to adjustment of the structure and material acquisition. The results showed that most dentistry courses had returned to on-site lessons in the early 2021, but private institutions reported higher proportion of return to on-site laboratory and clinical activities (AU).

RESUMO

Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time-consuming, especially in the highly diverse tropics. We aimed to provide a comprehensive repository of available flower-invertebrate interaction information for the Atlantic Forest, a South American tropical forest domain. Data were obtained from published works and "gray literature," such as theses and dissertations, as well as self-reports by co-authors. The data set has ~18,000 interaction records forming 482 networks, each containing between one and 1061 interaction links. Each network was sampled for about 200 h or less, with few exceptions. A total of 641 plant genera within 136 different families and 39 orders were reported, with the most abundant and rich families being Asteraceae, Fabaceae, and Rubiaceae. Invertebrates interacting with these plants were all arthropods from 10 orders, 129 families, and 581 genera, comprising 2419 morphotypes (including 988 named species). Hymenoptera was the most abundant and diverse order, with at least six times more records than the second-ranked order (Lepidoptera). The complete data set shows Hymenoptera interacting with all plant orders and also shows Diptera, Lepidoptera, Coleoptera, and Hemiptera to be important nodes. Among plants, Asterales and Fabales had the highest number of interactions. The best sampled environment was forest (~8000 records), followed by pastures and crops. Savanna, grasslands, and urban environments (among others) were also reported, indicating a wide range of approaches dedicated to collecting flower-invertebrate interaction data in the Atlantic Forest domain. Nevertheless, most reported data were from forest understory or lower strata, indicating a knowledge gap about flower-invertebrate interactions at the canopy. Also, access to remote regions remains a limitation, generating sampling bias across the geographical range of the Atlantic Forest. Future studies in these continuous and hard-to-access forested areas will yield important new information regarding the interactions between flowers and invertebrates in the Atlantic Forest. There are no copyright restrictions on the data set. Please cite this data paper if the data are used in publications and teaching events.

RESUMO

Abstract Iguaçu National Park is the second largest (1852.62 km²) protected area in the Atlantic Forest domain and harbors the largest area of semideciduous seasonal forest in Brazil. In this study, we present 795 subspecies and 787 species of butterflies that occur in this protected area and its surrounding areas, collected over 15 years and ten months using different non-standardized sampling methods. We also searched for additional records in the literature, entomological collections, and citizen science platforms on the internet. Among the sampled taxa, six are recorded for the first time in Brazil: Emesis orichalceus Stichel, 1916, Theope p. pakitza Hall & Harvey, 1998 (Riodinidae), Elbella v. viriditas (Skinner, 1920), Apaustus gracilis ssp. n. (Hesperiidae), Deltaya sp. n. (Nymphalidae), and Symbiopsis sp. n. (Lycaenidae). Another six are listed as endangered in lists of butterflies of conservation concern. The records for some species significantly increase previously documented distributions.


Resumo O Parque Nacional do Iguaçu é a segunda maior Unidade de Conservação (1.852,62 km²) no domínio Mata Atlântica, abrigando a maior área de Floresta Estacional Semidecídua no Brasil. Neste estudo apresentamos uma lista com 795 subespécies e 787 espécies de borboletas que ocorrem nesta Unidade de Conservação e seus arredores, coligida ao longo de 15 anos e dez meses através do uso de diferentes métodos de amostragem não padronizados. Nós também procuramos por registros adicionais na literatura, coleções entomológicas e plataformas de ciência cidadã na internet. Dentre os táxons amostrados, seis são registrados pela primeira vez para o Brasil: Emesis orichalceus Stichel, 1916, Theope p. pakitza Hall & Harvey, 1998 (Riodinidae), Elbella v. viriditas (Skinner, 1920), Apaustus gracilis ssp. n. (Hesperiidae), Deltaya sp. n. (Nymphalidae) e Symbiopsis sp. n. (Lycaenidae). Outras seis espécies são consideradas ameaçadas de extinção em listas de borboletas de interesse para a conservação. Os registros de algumas espécies aumentam significativamente as suas distribuições previamente documentadas.

RESUMO

Abstract The Global South has witnessed increasing sampling of its immense biological diversity during the past century. However, the diversity of many regions remains unknown, even at pristine and highly threatened places, such as in the Atlantic Forest; and for bioindicator, umbrella, and flagship groups. The present study reports the first butterfly list of the Parque Estadual Intervales, São Paulo, Brazil and surroundings, a key protected area in the last massive continuous of the Atlantic Forest. We compiled data from museums and four years of field work, under three sampling methods. We also aimed at providing resources to support conservation efforts by analyzing 27 years of climatic data (detailed in the Supplementary Material, in English and in Portuguese), discussing our results also for non-academics, and producing scientific outreach and educational material. A companion article dealt with the experiences of science outreach and capacity development, and illustrated the butterfly catalogue of the species sampled in the park. We found 312 species that sum to 2,139 records. The museum had 229 species (432 records), and we sampled 142 species (1,682 individuals), in a total effort of 36,679 sampling hours (36,432 trap and 247 net and observation hours). The richest families were Nymphalidae (148 species) and Hesperiidae (100 species). Most species were sampled exclusively by active methods (79.8%), but other sources (passive sampling, citizen science, etc.) also found unique records. We found the highest diversity metrics from January to May, and we demonstrated that winter months had less richness and abundance. We illustrated the 20 species common to all regions, and listed those that were found more than seven months in the year, as well as the most abundant species in trap sampling, with forest dwellers as well as species common to open and fragmented areas. The dominant species in our trap datasets was the iridescent white morpho, Morpho epistrophus (Fabricius, 1796), and we suggest it to become the park butterfly mascot.


Resumo O Sul Global testemunhou crescente amostragem de sua imensa diversidade biológica durante o século passado. Entretanto, a diversidade de muitas regiões permanece desconhecida, mesmo em locais pristinos e altamente ameaçados, como na Mata Atlântica; e para grupos bioindicadores, guarda-chuva e emblemáticos. O presente estudo reporta a primeira lista de borboletas do Parque Estadual Intervales, São Paulo, Brasil e arredores, uma unidade de conservação chave no último maciço contínuo de Mata Atlântica. Compilamos dados de museus e quatro anos de campo, sob três métodos de amostragem. Também visamos oferecer recursos para apoiar os esforços de conservação, analisando 27 anos de dados climáticos (detalhados no Material Suplementar, em inglês e em português), discutindo nossos resultados numa linguagem também para não acadêmicos, e produzindo material de divulgação científica e educativos. Um artigo irmão tratou das experiências de divulgação científica e capacitação, e ilustrou o catálogo de borboletas das espécies amostradas no parque. Encontramos 312 espécies em 2.139 registros. O museu tinha 229 espécies (432 registros), e amostramos 142 espécies (1.682 indivíduos), em um esforço total de 36.679 horas de amostragem (36.432 armadilhas e 247 horas de rede e observação). As famílias mais ricas foram Nymphalidae (148 espécies) e Hesperiidae (100 espécies). A maioria das espécies foi amostrada exclusivamente por métodos ativos (79,8%), mas outras fontes (passiva, ciência cidadã, etc.) também encontraram registros únicos. Encontramos as maiores métricas de diversidade de janeiro a maio, e demonstramos que os meses de inverno tiveram menos riqueza e abundância. Ilustramos as 20 espécies comuns a todas as regiões, e listamos aquelas que foram encontradas em mais de sete meses no ano, bem como as espécies mais abundantes em armadilhas, com espécies florestais e também comuns em áreas abertas e fragmentadas. A espécie dominante em nossas armadilhas foi a morfo branca iridescente, Morpho epistrophus (Fabricius, 1796), e sugerimos que se torne a borboleta mascote do parque.

RESUMO

OBJECTIVE: We evaluated the impact of direct and indirect medical costs incurred through chikungunya infections in patients treated in Fortaleza, Brazil. METHODS: Cross-sectional study about the cost of illness. The valuation method of medical costs was based on the micro-costing approach (bottom-up). The study was carried out in a large general hospital of the private health network. The study population consisted of patients treated as suspected cases of chikungunya and hospital professionals who applied for sick leave due to chikungunya. RESULTS: In 2017, there were 2683 patients treated at this hospital who incurred an estimated cost of $383,514.40. From this amount, $174,322.91 (45.5%) were expended on emergency care, $194,700.59 (50.8%) on hospitalisations. 123 hospital professionals were infected with chikungunya and sick leave duration ranged between 1 and 19 days. Health professionals generated 746 days of absence and an amount of $14,490.90 due to absenteeism from work related to chikungunya. 31 symptoms were reported, especially arthralgia (91.1%) and fever (79.4%). There was a predominance of females (58.8%) and the age group of 20-39 years (42.1%). CONCLUSION: The average cost of admissions was over $2400. Considering the epidemic potential of chikungunya, our data indicate the huge economic burden of this disease to healthcare units in the presence of epidemics. Economic factors, added to the loss of life and the consequences of chronic chikungunya, make this disease a real scourge for countries with fewer material resources.

RESUMO

Recent reviews of data on worldwide insect decline include almost no information on Brazil. We gathered evidence from literature searches and a survey sent to researchers, to which 96 replied and 56 provided information and publications. We present 75 instances of trends recorded over an average span of 11 years for aquatic and 22 years for terrestrial insects. These include time-replicated samples and expert opinion based on long-term local collections. Most terrestrial data are for butterflies, bees and scarab beetles. Aquatic studies include several insect orders, usually sorted to genus or family. Terrestrial insects showed significantly more cases of declines than increases, both in abundance (17 : 3) and in diversity (11 : 1). In aquatic cases, no tendency was detected in abundance (2 : 2) or diversity (3 : 4), not counting cases with no trend. Differences in these results among habitats may be due to the shorter span and less change in environmental conditions in the aquatic surveys, which included sites already degraded before sampling. We offer guidelines for future long-term assessments, including resampling of legacy collection sites.
