“…Habitat integrity summarises coverage of riparian forest, the land use adjacent to the riparian zone and some characteristics of the stream channel, such as bank structure of rivers (Hannaford et al ., ; Roy et al ., ; Nessimian et al ., ), and can be interpreted as forest cover (Nessimian et al ., ). Indeed, this variable is an important predictor of Zygoptera species richness and composition in Amazonia (Monteiro Júnior et al ., ; Oliveira‐Junior et al ., ; Brasil et al ., ) and other Brazilian biomes (De Marco et al ., ; Mendes et al ., ). With increasing forest cover, the dominance of damselfly species increases, while the dominance of dragonflies decreases (De Marco et al ., ).…”

Large Amazonian rivers may act as dispersal barriers for animals with low dispersal abilities, limiting their distribution to certain interfluves. Consequently, the distribution of these taxa would be less affected by macroclimatic gradients. Conversely, high‐dispersal taxa would be less constrained by large rivers and may track suitable climates. We evaluate whether Zygoptera and Anisoptera, two Odonata suborders with different dispersal abilities, show differences in distribution patterns across Amazonian interfluves. We further assess the relative importance of macroclimatic and habitat factors in their community assembly. We used network modularity analyses to identify biogeographic species pools and spatial buffers to define metacommunity species pools. Then, we used structural equation models to estimate the relative importance of multi‐scale factors on species richness patterns. Zygoptera communities are more similar in species composition within than between interfluves, suggesting that large Amazonian rivers indeed limit the distribution of Zygoptera species. Conversely, the distribution of Anisoptera extends across Amazonian interfluves. Seasonality has a strong positive effect on Zygoptera and Anisoptera richness across scales. In addition, habitat integrity is negatively correlated with the regional species richness and abundance of Anisoptera and positively correlated with Zygoptera local richness. The contrasting effects of habitat integrity on Anisoptera and Zygoptera suggest that the former is favored in open habitats, whereas the latter is so in forests. Despite these differences, both suborders appear to follow similar community assembly mechanisms in Amazonia, with a strong climatic control across scales and an effect of habitat filters on local communities.

“…Many researchers (e.g., Schindler et al, 2003;Remsburg and Turner, 2009;Buczyński, 2015;Oliveira-Junior et al, 2015) stressed the importance of riparian vegetation on the species richness and distribution of Odonata species. On the other hand, various studies emphasized the negative influence of human activities caused by urbanization and agricultural activities on the distribution and diversity of Odonata, which generally lead to a decrease and homogenization in the richness of Odonata species (Buczyński and Lewandowski, 2011;Willigalla and Fartmann, 2012;Harabiš and Dolny, 2012;Monteiro-Junior et al, 2015). Nevertheless, Goertzen and Suhling (2013) showed that moderately disturbed ruderal and pioneer ponds in residential and agricultural areas increase the number of Odonata species.…”

-Karstic springs are important habitats for maintaining freshwater biodiversity. However, little is known about Odonata larvae assemblages in karstic springs, and studies about the ecological factors that determine species distribution in these habitats are still lacking. In this study the composition of Odonata larvae communities from 91 springs located in the central part of Montenegro was investigated. The richest fauna was found in sublacustrine springs, followed by limnocrenes, while that of the rheocrenes was less rich. The results obtained confirm the main research hypothesis that Odonata larvae assemblages in the karstic springs in the central part of Montenegro were comparably influenced by the environmental parameters acting on the level of individual springs as well as the factors acting at the landscape level. Odonata larvae assemblages divided springs into four groups. On the other hand, the springs could be divided into three groups based on habitat and landscape characteristics. CCA indicates that disturbance factors such as the permanence and directness of human influence on springs for use as drinking water sources are foremost in determining Odonata assemblages at the level of individual springs. The habitat scale considered several factors that influence Odonate assemblages, including altitude and riparian vegetation. This study proves that further odonatological studies in springs should include both types of factors and their interactions.Keywords: Odonata / Montenegro / springs / crenobiology / diversity Résumé -Patterns écologiques des assemblages d'Odonates dans les sources karstiques du centre du Monténégro. Les sources karstiques sont des habitats importants pour le maintien de la biodiversité des eaux douces. Cependant, on sait peu de choses sur les assemblages de larves d'odonates dans les sources karstiques et des études sur les facteurs écologiques qui déterminent la répartition des espèces dans ces habitats font toujours défaut. Dans cette étude, la composition des communautés de larves d'odonates de 91 sources situées dans la partie centrale du Monténégro a été étudiée. La faune la plus riche a été trouvée dans les sources sublacustres, suivies par les limnocrènes, tandis que celle des rhéocrènes était moins riche. Les résultats obtenus confirment la principale hypothèse de recherche selon laquelle les assemblages de larves d'odonates dans les sources karstiques dans la partie centrale du Monténégro étaient influencés par les paramètres environnementaux agissant au niveau de chaque source ainsi que par les facteurs agissant au niveau du paysage. Les assemblages de larves d'odonates ont séparé les sources en quatre groupes. Par ailleurs, les sources pourraient être divisées en trois groupes en fonction des caractéristiques de l'habitat et du paysage. La CCA indique que des facteurs de perturbation tels que la permanence et l'influence humaine directe sur les sources utilisés comme sources d'eau potable sont essentiels pour déterminer les assemblages d'odonates au niveau de...

“…We collected adult dragonflies (Anisoptera and Zygoptera) with a hand net along a 100-m transect at each stream and parallel to both the stream banks, for 1 h in each stream, on sunny days between 10:00 h and 15:00 h, an approach that is known to be effective for sampling dragonflies (e.g. Monteiro-Junior et al, 2015;Calvão et al, 2016). Sampling was conducted once at each site, between the years of 2011 to 2013.…”

“…It can also increase inter-specific competition and larval mortality rates, and constrain dispersal behaviour for some species. In contrast, some other species may benefit from anthropogenic changes to the landscape, for example an increase in their preferred habitat type (Corbet, 1999;Remsburg & Turner, 2009;Lancaster et al, 2010;Kutcher & Bried, 2014;De Marco et al, 2015;Dutra & De Marco, 2015;Monteiro-Junior et al, 2015). Therefore, the association of behavioural traits that are sensitive to local environmental conditions might be considered a robust tool for indicative or even predictive studies in community ecology (Poff et al, 2006;Heino & Peckarsky, 2014).…”

Oviposition site selection by aquatic insects is usually influenced by both aquatic and terrestrial cues. Landscape changes (e.g. native vegetation loss) can affect the level of the reproductive success in aquatic insects, changing local species composition and richness. We investigate whether forest cover loss around streams influences the number of species with exophytic (species which lay eggs directly on the water surface), endophytic (species which lay their eggs directly into plant tissue), or epiphytic (species which lay eggs on the exposed surface of rocks, leaves, trunks or other substrates protruding from the stream surface) oviposition behaviour in dragonfly assemblages. We sampled adult dragonflies in 116 streams in a Neotropical savanna region in Brazil. The relationship between species richness for each behavioural category, and the proportion of forest cover around the streams, was tested using regression analysis. We collected 2413 dragonfly (Anisoptera and Zygoptera) individuals, belonging to 8 families, 30 genera, and 63 species. Of these, 25 species were classified as exophytic, 28 as epiphytic, and 10 as endophytic. Our results show that the number of species with exophytic or epiphytic behaviour was strongly related to riparian forest loss. Forest loss changes the habitat, and here, specifically changes site suitability for oviposition. We highlight the importance of using behavioural traits as a bioindicator tool for the assessment of anthropogenic impacts on tropical forest.
