Interspecific interactions, such as competition, are among the key factors that determine the distribution, abundance and diversity of organisms in natural communities of aquatic ecosystems. However, a marked reduction in the environmental integrity of streams may lead to modifications of the natural dynamics of these communities, including co‐occurrence patterns and body size. In the Amazon, the replacement of forests by production systems is one of the leading causes of alterations to riverine ecosystem. The insects of the order Odonata (dragonflies and damselflies) are predators known to compete for environmental resources but are also sensitive to environmental changes such as those caused by shifts in land use. In this scenario, the present study evaluated species co‐occurrence and body size patterns in adult odonates found at preserved and altered Amazonian streams, to determine whether there are morphological differences among the species that enable their coexistence. During the study, 98 streams in the eastern Amazon region were sampled, and a habitat integrity index (HII) was used to evaluate the integrity of each stream (based on variables such as the condition of the riparian vegetation and channel, and land use). Ten male individuals were selected from each species, and nine morphometric measurements were taken from each individual. A total of 3588 specimens were collected and distributed in nine families, 49 genera and 134 species. We found a non‐random pattern of co‐occurrence in the species of the odonate suborder Zygoptera and a random pattern in the suborder Anisoptera, in both preserved and altered streams. We found morphological divergence between pairs of zygopteran species, in the whole sample and both categories of stream integrity separately. No such morphological divergence was found in the pairs of anisopteran species. The distribution patterns of odonate species are limited by specific environmental processes, especially in preserved environments and in specialists, such as most zygopterans. Zygopteran species have more specific microhabitat requirements, which could explain this pattern, whereas anisopterans prefer open environments, which usually have a greater supply of resources, although there tends to be less microhabitat heterogeneity, which leads to reduced competition. Given this, future studies should use limiting similarity (e.g. morphological attributes) in addition to environmental and spatial factors to better understand the factors structuring these communities. Among these mechanisms, the effects of common ancestry (phylogenetic inertia) and biogeography are important factors that should also be considered in future studies.

Alternative tourism (AT) contributes to conservation, valuing the environment and recipient cultures with minimal impact, especially in protected areas. In this context, this article identified, considering the residents’ perception, the possible environmental impacts resulting from alternative tourism in communities of the Tapajós-Arapiuns Extractive Reserve (RESEX), Brazilian Amazonia. Thus, between February and April 2019 a semi-structured interview was conducted with 122 residents of three communities of RESEX (Anã, Maripá, and São Miguel). The interview script was divided into three groups of questions: (i) interviewee data, (ii) socioeconomic data, and (iii) perception of the concept and environmental impacts of alternative tourism. We used a snowball sampling method, which consists of a form of a non-probabilistic sample. The majority (91.8%) of the informants did not know how to explain the concept of alternative tourism; however, for 87.7% of them, this tourism does not generate negative impacts. Income is the most used expression (53%) by RESEX residents to demonstrate what alternative tourism positively impacts. About 74.6% of respondents reported that tourists do not influence local customs change, and 94.3% do not identify tourism-related violence. Finally, 89.3% say that tourists do not pollute the environments. The research carried out in this Conservation Unit deserves the attention of decision-makers, managers, technicians, and researchers. It provides subsidies for management programs to provide real bases for the analysis, interpretation, and planning of sustainable tourist spaces.

Conservation initiatives overwhelmingly focus on terrestrial biodiversity, and little is known about the freshwater cobenefits of terrestrial conservation actions. We sampled more than 1500 terrestrial and freshwater species in the Amazon and simulated conservation for species from both realms. Prioritizations based on terrestrial species yielded on average just 22% of the freshwater benefits achieved through freshwater-focused conservation. However, by using integrated cross-realm planning, freshwater benefits could be increased by up to 600% for a 1% reduction in terrestrial benefits. Where freshwater biodiversity data are unavailable but aquatic connectivity is accounted for, freshwater benefits could still be doubled for negligible losses of terrestrial coverage. Conservation actions are urgently needed to improve the status of freshwater species globally. Our results suggest that such gains can be achieved without compromising terrestrial conservation goals.

As abelhas da tribo Euglossini (Hymenoptera: Apidae) são extremamente importantes na polinização das florestas neotropicais e por serem sensíveis a mudanças em seu habitat, são consideradas excelentes bioindicadores de qualidade ambiental. Nesse contexto, o presente estudo objetivou (i) comparar a riqueza de espécies e abundância de indivíduos de Euglossini entre fragmento de floresta, pastagem e plantação de soja; (ii) identificar a preferência pelas iscas odoríferas; e (iii) avaliar o efeito de borda sobre a riqueza de espécies e abundância de indivíduos. O estudo foi realizado no município de Mojuí dos Campos, Pará, Brasil, em três áreas: fragmento de floresta, pastagem e plantação de soja. Utilizou-se seis iscas odoríferas para atrair os machos: eugenol, eucaliptol, vanilina, benzoato de benzila, cinamato de metila e geraniol. Foram coletados 1668 indivíduos distribuídos em quatro gêneros e 11 espécies. Existe diferença significativa na abundância de Euglossini entre os ambientes (F(2,24) = 4,1007; p = 0,029), a maior abundância ocorreu na área de pastagem (866-52%). Houve diferença significativa tanto na abundância (F(5, 156) = 15,811; p < 0,001) quanto na riqueza de espécies (F(5, 156) = 70,039; p < 0,001) de Euglossini entre as iscas. Vanilina mostrou-se a isca mais atrativa e geraniol a menos atrativa. Não há diferença significativa na abundância (F(2, 24) = 1,8505; p = 0,178) e riqueza de espécies de Euglossini (F(2, 24) = 0,299; p = 0,744) entre os transectos borda, intermediário e centro, o que pode estar relacionado com a proximidade entre as áreas e a capacidade das abelhas de voar longas distâncias. Outro fator que pode influenciar nesse resultado, é a capacidade de dispersão dessas abelhas, que possibilita a exploraração localidades próximas. Fatores climáticos, diferença na volatilidade das substâncias, faixa etária das populações, pureza e composição isométricas das substâncias e ofertas de fontes naturais podem ter influenciado nesse resultado. Apesar dos resultados mostrarem um alto grau de degradação na área estudada, é necessário a realização de mais estudos, que levem em conta o tamanho dos fragmentos e o número de Eulaema nigrita em relação a outras espécies para que se possa obter dados mais precisos sobre os impactos dos diferentes usos da terra na diversidade das abelhas Euglossini.

Citizen science activities, involving local people in volunteer-supported and sustainable monitoring programs, are common. In this context, the objective of the present work was to develop a simple Metric of Aquatic Invertebrates for Volunteers (MAIV), including a user-friendly tool that can be easily accessed by volunteers, and to evaluate the efficiency of a volunteer monitoring program following an audit procedure. To obtain MAIV values, macroinvertebrate communities were reduced to 18 surrogate taxa, which represented an acceptable compromise between simplicity, efficiency, and reproducibility of the data, compared to the regular Water Framework Directive monitoring. When compared to results obtained with the National Classification System of Portugal, MAIV accurately detected moderate, poor, and bad ecological status. Thus, MAIV can be used by volunteers as a complement to the official monitoring program, as well as a prospective early warning tool for local problems related to ecological quality. Volunteers were students supervised by their teachers. Results obtained by volunteers were compared to results obtained by experts on macroinvertebrate identification to measure the efficiency of the procedure, by counting gains and losses on sorting, and identification. Characteristics of groups of volunteers (age and school level) did not influence significantly the efficiency of the procedure, and generally results of volunteers and experts matched.

Since early studies about aquatic ecology, it has been found that changes in environmental conditions alter aquatic insect communities. Based on this, the combined study of environmental conditions and aquatic insect communities has become an important tool to monitor and manage freshwater systems. However, there is no consensus about which environmental predictors and facets of diversity are more useful for environmental monitoring. The objective of this work was to conduct a scientometric analysis to identify the main environmental predictors and biological groups used to monitor and manage lotic freshwater systems. We conducted a scientometric study on the Web of Science platform using the following words: stream, river, aquatic insect, Ephemeroptera, Plecoptera, Trichoptera, Odonata, Heteroptera, Chironomidae, bioindicator, environmental change, anthropic, and land use. Although most of the environmental predictors employed are local, intrinsic of freshwater systems using local environmental and associated landscape variables is a better strategy to predict aquatic insect communities. The facets of diversity most used are composition and richness of species and genera, which are not efficient at measuring the loss of ecosystem services and extinction of phylogenetic lineages. Although very important, these functional and phylogenetic facets are poorly explored for this purpose. Even though tropical regions are the most diverse globally and are experiencing major losses of native vegetation, these ecosystems are the least studied, a knowledge gap that needs addressing to better understand the effect of anthropogenic activities on the diversity of aquatic insects.

Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the Amazonian region. Adult Odonata were sampled in 98 streams in the Eastern Amazon, Pará, Brazil. Six variables were used to measure local environmental factors: habitat integrity index; mean canopy over the channel; and four physical and chemical descriptors of the water. To measure regional environmental factors, six variables were also used: altitude gradient, three bioclimatic variables and two percentage forest variables. In partial redundancy analysis, both abiotic factors (local and regional) were important to explain the variation in the Odonata community. The Odonata community can be influenced by regional and local factors. The relationship between Odonata and the local (e.g., integrity, canopy cover, and physical and chemical descriptors of the water) and regional (e.g., bioclimatic and forest cover variables) environmental variables recorded in this study has important implications for the use of these organisms to monitor small streams of the Eastern Amazon. The scale at which habitat is measured is an important issue in community structuring studies considering the rapid environmental changes. It is of great importance to consider the different scales in studies assessing community structure, once an adequate habitat must meet the ecological needs of all stages of the life of the Odonata.

The evaluation of the effects of environmental factors on natural communities has been one of the principal approaches in ecology; although, over the past decade, increasing importance has been given to spatial factors. In this context, we evaluated the relative importance of environmental and spatial factors for the structuring of the local odonate communities in preserved and altered streams. Adult Odonata were sampled in 98 streams in eastern Amazonia, Brazil. The physical features of each stream were evaluated and spatial variables were generated. Only environmental factors accounted for the variation in the Odonata community. The same pattern was observed in the suborder Zygoptera. For Anisoptera, environmental factors alone affect the variation in the community, considering all the environments together, and the altered areas on their own. As the two Odonata suborders presented distinct responses to environmental factors, this partitioning may contribute to an improvement in the precision of studies in biomonitoring. We thus suggest that studies would have a greater explanatory potential if additional variables are included, related to biotic interactions (e.g., competition). This will require further investigation on a finer scale of environmental variation to determine how the Odonata fauna of Amazonian streams behaves under this analytical perspective.

The accumulation of scientific knowledge is far outstripped by the rate of environmental disturbance from human activities in aquatic habitats. This highlights the need to develop effective proxy measures of aquatic biodiversity that can demonstrate changes in communities associated with human activities. We evaluated whether the relative abundance and species richness of Anisoptera and Zygoptera can be used as a tool to measure environmental impacts on Amazonian streams. Adult of Anisoptera and Zygoptera were sampled in 50 Amazonian streams, in the municipality of Paragominas (Pará state), Brazil, using an entomological handnet. The physical features of each stream were evaluated using an index of environmental integrity (HII). We collected a total of 1769 Odonata specimens, representing 97 species (56 were Zygoptera and 41 were Anisoptera). Habitat modification resulted in an inversion in the proportional abundance and species richness of Anisoptera and Zygoptera, where Zygoptera diversity decreased with the loss of habitat integrity, whereas Anisoptera diversity increased with habitat disturbance. A decline of 0.1 in the habitat integrity index score resulted in an increase of approximately 13 individuals and 11 species of Anisoptera, with the exact opposite effect observed for the Zygoptera. In summary, the Odonata proved to be a useful model for the assessment of Amazonian streams, with sites where more than 54% of the Odonata species were Zygoptera being classified as preserved, and those dominated by Anisoptera species (> 59%) being considered degraded. This approach has clear applications for environmental impact assessments, as it reduces the influence of sampling effort and collector experience on assessment outcomes, and does not rely upon specialist knowledge, given that members of the two suborders are easily distinguished from one and other in the field.

Species occurrence can be affected by the availability of environments that fit within the limits of variation of its niche and by interaction with other species. Modifications in the environment, especially those caused by mankind, are considered the leading cause for species extinction. Such a response from the species is not random, with patterns that can follow functionality and/or morphology of each taxa. In this context, the objective of this study was to assess how environmental factors affect adult Odonata species, testing the hypotheses: a) that the environment acts as a filter upon the species by means of facilitating or excluding specific characteristics and b) that because of the order’s requirements for thermoregulation and reproduction, thorax width and oviposition type are the variables most affected in the group. A total of 97 streams were sampled in eastern Amazonia, distributed along a gradient of different states of preservation, from completely preserved to heavily impacted by plantations and livestock. Six functional characteristics and seven environmental descriptors were selected, and to assess their relationships, a combination of Fourth Corner and RLQ analysis was used. The Habitat Integrity Index was the descriptor with the biggest impact on the Odonata community, presenting a negative correlation with wing width, thorax width and exophytic oviposition, and a positive correlation with endophytic oviposition. Macrophyte cover was the next most relevant environmental descriptor, showing a negative correlation with abdomen length, and positive correlation with thorax width and exophytic oviposition. The results show that poorly preserved environments favour the occurrence of organisms with a wider thorax and the substitution of endophytic oviposition with the exophytic type. Since changes to the environment do not usually alter Odonata richness but rather the composition, these results show a favouritism for groups with mentioned characteristics, such as Libellulidae, to the detriment of other groups (especially Zygoptera), which can result in community homogeneity and both biodiversity and functional loss. The maintenance of well-preserved environments is therefore indispensable in assuring Odonata biodiversity, as well as the best way to preserve the different behavioural and ecophysiological groups in the order. The Odonata community’s response, directed through its morphological and behavioural characteristics, sheds light on ecological patterns, and thus the addition of oviposition habits in conservation measures aimed at preserving the order can render them more adequate, as this is a critical aspect of population maintenance and colonization of new sites.

The presence of riparian vegetation provides microclimatic regulation of stream conditions [e.g. luminosity (lux), air temperature (°C) and relative humidity (%)], which varies naturally throughout the day. These variables explain the diurnal behaviour patterns of ectotherms such as Odonata in natural areas. However, human land uses (e.g. pastures) modify the abiotic conditions of riparian environments, favouring the presence of disturbance-tolerant species. In this context, we assess relationships between riparian land use (control streams-natural areas and pasture), abiotic conditions habitat integrity index (in control and pastures streams), (air temperature, luminosity and humidity in control streams), and Odonata diversity (between pasture and control streams and throughout the time of day) in Brazilian savannah (Cerrado) streams. First, the control streams had higher habitat integrity index than pasture. Higher abundance and difference in composition of Odonata species were observed in streams surrounded by pasture relative to natural areas. The conversion of natural areas to pasture near streams was also accompanied by an increase in overall body size of Odonata species. Odonata species richness and abundance in natural areas varied throughout the day, but peaked around 12:00 h, coinciding with changes in air temperature and luminosity. Our study highlights that changes in the physical characteristics of streams through conversion of natural habitats to pasture will change environmental conditions and act as a filter on the distribution and persistence of Odonata species in Cerrado streams.

Ações antrópicas, como a remoção da vegetação ripária, causam prejuízos ao homem e à natureza; essa, quando integrada, exerce grande influência positiva sobre o corpo d’água; quando retirada, pode causar alterações físicas e bióticas sobre os ecossistemas aquáticos e os indivíduos que nela habitam. Neste contexto, foi avaliado o efeito da cobertura de dossel sobre a comunidade de Odonata na região Santarém-Belterra, Pará, Brasil. Para o estudo, foram amostrados 48 igarapés, estes que, para suas classificações, quanto aos níveis de conservação, foi aplicado o Índice de Integridade do Habitat. Para a amostragem biológica, os cursos foram medidos por uma distância de 100m ao longo de sua extensão, subdivididos em 20 segmentos de 5m cada, os Odonatas adultos foram capturados por uma rede entomológica durante 3 minutos em cada seguimento. Através de IIH, classificamos 26 igarapés, com integridade alterada e 22 preservadas. Foram coletados 1819 insetos, sendo 365 da subordem Anisoptera e 1454 de Zygoptera. Os valores obtidos através regressão linear apontaram que, com o aumento de aproximadamente 0,2 de IIH, ocorre um decréscimo de aproximadamente oito indivíduos e uma espécie de Anisoptera e aumento de aproximadamente sete indivíduos e uma espécie de Zygoptera. As maiores riquezas de espécies de Anisoptera ocorreram em igarapés classificados como alterados (t=2,072; p=0,043), para Zygoptera, este índice foi maior em igarapés classificados como preservados (t=2,387; p=0,021). Com aumento de aproximadamente 10% na cobertura de dossel, há um decréscimo de aproximadamente três indivíduos e uma espécie de Anisoptera e um aumento de aproximadamente dois indivíduos e uma espécie de Zygoptera com o mesmo percentual. A diferença na distribuição dos indivíduos da ordem Odonata pode ser explicada por suas exigências ecofisiológicas inerentes a cada subordem. Onde a vegetação ripária exerce maior influência sobre a riqueza das espécies. Dada a especificidade de cada subordem, elas podem ser utilizadas como bioindicadores de qualidade do hábitat.

No município de Santarém (PA), é comercializada uma grande quantidade de artesanatos utilizando animais aquáticos como matéria-prima. Essa arte é denominada zooartesanato. O presente trabalho apresenta a identificação das espécies de pescados utilizados e comercializados em feiras artesanais e seu enquadramento na lista vermelha de espécies ameaçadas de acordo com a IUNC (União Internacional para a Conservação da Natureza e dos Recursos Naturais). As coletas dos principais pescados e seus subprodutos comercializados como artesanatos foram realizados em duas feiras artesanais: Terminal Fluvial de Santarém e Cristo Rei, e três lojas de Santarém, e em seis lojas artesanais na vila balneária de Alter-do-Chão, sendo classificadas como utilitárias, figurativas e zoológicas. Foram registradas 27 espécies de animais aquáticos, sendo que o número de espécies mais representativas se enquadra no Filo Mollusca (Classe Bivalvia e Gastropoda), com um total de 14 espécies identificadas. O Filo Chordata (Classe Actinopterygii) obteve um total de 12 espécies, e Filo Arthropoda (Classe Malacostraca) foi registrado somente um exemplar. De acordo com as categorias da lista vermelha da IUNC, a maioria das espécies consta como não identificadas (NE), entretanto a Lutjanus analis (CUVIER, 1828) está enquadrada na categoria quase ameaçada (NT). Constatou-se que muitas espécies aquáticas são utilizadas na fabricação de zooartesanato, e vale ressaltar que essa é uma atividade exploratória, gerando impactos à fauna aquática regional.

Estudos sobre estruturação de comunidades biológicas tem sido uma das principais abordagens em ecologia. Identificar as populações de determinada localidade nos possibilita propor estratégias direcionadas de conservação dos ecossistemas naturais que estão sendo modificados pelas ações humanas. Nesse contexto, foi realizado um levantamento da diversidade de espécies de Odonata adultos (Insecta) em corpos hídricos localizados na Reserva Extrativista Tapajós-Arapiuns (RESEX), Santarém/Aveiro (PA). Com uso de rede entomológica, foram amostrados adultos de Odonata em oito igarapés da RESEX. Os igarapés foram amostrados no mês de outubro de 2017. Cada igarapé foi amostrado uma vez em diferentes dias, totalizando oito coletas. Foram avaliados através de índices ecológicos a riqueza (Jackknife de primeira), diversidade (Shannon (H’) e Simpson (D)), dominância (Berger-Parker) e constância (Dajoz). Foram coletados 230 indivíduos de Odonata, distribuídos em oito famílias, 17 gêneros e 19 espécies. A riqueza estimada de espécies foi de 25,96 ± 2,40 (média ± desvio padrão), e a eficiência de coleta foi de 95%. Encontramos uma considerável diversidade de espécies (H’ = 2,14; D = 0,83). A espécie com maior dominância foi Chalcopteryx radians, com 62 indivíduos (26%). Das 19 espécies coletadas, sete foram classificadas como constantes (36%), seis como acessórias (32%), e seis acidentais (32%). A existência de uma grande diversidade de flora local possibilita para maioria dos indivíduos, um maior número de microhábitats, como no caso de Odonata. O fato de o levantamento ter sido realizado dentro de uma unidade de conservação, que possui atributos essenciais para manutenção das comunidades de Odonata, foi decisivo para existência da diversidade de espécies encontradas no levantamento. Ambientes estáveis, como no caso de áreas de preservação, podem proporcionar comunidades ricas de espécies. Essas características da RESEX acabaram possibilitando a dominância de espécies do gênero Chalcopteryx. Fêmeas desse gênero apresentam uma alta especilização de habitat, no qual necessitam de habitat especifico para ovipositar e, portanto, são encontradas basicamente em ambientes preservados. Considerando os resultados apresentados, é de grande importância manter a RESEX com sua integridade intacta e a realização de novos levantamentos da odonato, fauna com maior esforço amostral, para determinar de maneira mais consistente a diversidade local e possibilitar a utilização desses indivíduos em trabalhos de manejos da RESEX.

A implantação de grandes projetos na Amazônia apresenta dinâmicas marcadas por impactos. Este trabalho descreve os impactos socioambientais gerados por um grande empreendimento comandado pela empresa multinacional Aluminum Company of America - ALCOA, no município de Juruti (PA), na visão dos moradores da área urbana. Trata-se de uma pequena cidade no interior do estado do Pará, que se incorpora à economia global devido ao ciclo produtivo do alumínio, através da extração de bauxita. A metodologia aplicada consistiu na utilização de questionários, como instrumento para a coleta de dados em nove bairros, com posterior elaboração de gráficos, tabelas e cujos valores obtidos foram sumarizados pela Análise de Componentes Principais (PCA) para verificar a distinção entre dois grupos de bairros, definidos como antigos e recentes. A pesquisa apontou que, no que concerne à infraestrutura, à saúde, e ao meio ambiente, houve tanto impactos positivos, quanto negativos; já no que diz respeito ao crescimento populacional desordenado e à criminalidade, apenas negativos; enquanto que, no que se relaciona à educação, ao emprego e à economia, somente efeitos positivos. Percebe-se, portanto, que, em Juruti, houve mais impactos positivos do que negativos. O presente estudo contribui para o entendimento de que as transformações ocorridas são desdobramentos das relações existentes entre os circuitos espaciais produtivos e os locais afetados, bem como das interações sociais, econômicas e ambientais estabelecidas no município.

Our objectives were to assess how turnover and nestedness contribute to beta-diversity patterns of the Zygoptera in Amazonian streams, and to relate these components of beta diversity to environmental, spatial and biogeographic predictors. Our first hypothesis is that the turnover is the most important component of beta-diversity patterns due to the historical isolation of all or part of the areas located in the interfluves of the major Amazonian rivers. Our second hypothesis is that the interaction between environmental conditions and the area of endemism (biogeography) would be the most important predictor of beta-diversity patterns.To test these hypotheses, we compiled data on the Zygoptera communities from 172 Amazonian streams. We used three sets of predictor variables: (i) environmental variables, (ii) area of endemism (biogeographic) and (iii) spatial filters.The turnover explained 99.36% of the beta diversity, corroborating our first hypothesis. Together, environmental and biogeographic variables were the best predictors of beta-diversity patterns. For turnover, however, the biogeographic variables were the best predictors, contrary to our second hypothesis.We found high gamma diversity, but low alpha diversity in the Zygoptera communities. This paradox is explained by the high turnover among sites within the study landscape. This pattern of diversity is related to both historical biogeographic factors and the spatial structuring of environmental conditions in the Amazon region. In the light of our results (high turnover and beta diversity), and their correspondence with areas of endemism, adequate conservation of Amazonian Zygoptera diversity will depend on the establishment of so-called mega-reserves throughout the major Amazonian interfluves and, whenever possible, in the areas with adequate environmental conditions for the greatest possible number of species, otherwise, most species may be at a constant risk of extinction.
