“…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...

“…In recent years, the interest in the entomofauna of postindustrial sites has increased (Babin-Fenske and Anand 2011; Milisa et al 2010;Tropek et al 2010;Harabiš and Dolný 2012;Heneberg 2012;Srba and Heneberg 2012). In particular, post-mining sites, which are typically highly degraded or even destroyed, represent habitats where succession starts on bare substrate.…”

Evidence-based conservation allows the evaluation of both the collateral benefits and the drawbacks of a wide range of human activities, like quarrying. In this study, the community structure of bees and wasps (Hymenoptera:Apocrita) in Central European sandpits was investigated, focusing on the changes caused by quarrying cessation and technical reclamation, as well as on the changes caused by spontaneous succession leading to the increased availability of food resources but also to the loss of the number and size of available bare sand patches. The bees and wasps demonstrated an exceptional ability to colonize the newly emerging sand quarrying areas, and to survive in them unless these were quarried as intensively as to not allow the development of any early successional vegetation. Both active and closed sandpits were found to serve as important regional refuges for the persistence of many rare species. In total, 221 species were detected, 53 of those were red-listed, with two species thought to be regionally extinct. Typically, active quarrying was associated with the presence of Bembecinus tridens, Halictus subauratus, H. maculatus, and Andrena nigroaenea. The list of the species of conservation interest is provided, and so is the detailed analysis of the life-history traits of the species in relation to the presence of bare sand patches, vegetation cover, quarrying intensity, and time elapsed since the formation of each artificial habitat patch. Sandpits as refuges for xerothermophilous and psammophilous hymenopterans are usually completely and irreversibly lost if the current legislature enforcing the technical reclamation over spontaneous or assisted succession is applied in all or most of the post-mining areas.

“…However, Odonata species richness is lower with increasing urbanization, indicating that urbanization has a negative effect on the species diversity of Odonata (Willigalla and Fartmann, 2012), since most of their larvae require specific ecological conditions and are very sensitive to environmental changes (Harabiš and Dolný, 2012). Likewise, low values of beta diversity may be related to increasing urbanization and the expansion of agriculture in the vicinity of the streams of the Pirapó River basin.…”

Does the habitat structure control the distribution and diversity of the Odonatofauna?

The statement that the habitat complexity and structure govern the abundance and diversity of biological communities has been widely investigated. In this context, we assumed the hypothesis of habitat heterogeneity, that is, the higher habitat complexity leads to greater diversity of Odonata. In addition, we analyzed the influence of habitat structure on the distribution of this community, and evaluated the effects of abiotic variables. Odonata larvae were collected with sieves and by electrofishing in ten neotropical streams belonging to the Pirapó River basin. Forty species of Odonata were registered, which were distributed in eight families, Libellulidae stood out with the highest richness. The high gamma diversity and distribution of Odonata were associated with habitat heterogeneity in these streams. However, the abiotic variables also seem to affect the distribution of Odonata species, in view of the impact of the land use in the vicinity of streams.Keywords: insect, habitat heterogeneity, structural complexity, streams.A estrutura do habitat controla a distribuição e diversidade da Odonatofauna?Resumo O fato de que a complexidade e estrutura de habitat são reguladores da abundância e diversidade de comunidades biológicas tem sido amplamente investigada. Neste contexto, assumimos a hipótese da heterogeneidade de habitat, ou seja, maior complexidade de habitat conduz a maior diversidade de Odonata. Além disso, foi analisada a influência da estrutura do habitat sobre a distribuição desta comunidade, além de avaliar os efeitos das variáveis abióticas. As larvas de Odonata foram coletadas com peneiras e através da pesca elétrica em dez riachos neotropicais pertencentes à bacia hidrográfica do rio Pirapó. Foram registradas quarenta espécies de Odonata, distribuídas em oito famílias, Libellulidae destacou-se com maior riqueza. A elevada diversidade gama e distribuição de Odonata foram associadas à heterogeneidade de habitat presentes nestes riachos. No entanto, as variáveis abióticas da água parece também ter efeito sobre a distribuição de espécies de Odonata, tendo em vista o impacto do uso do solo dos riachos.Palavras-chave: insetos, heterogeneidade de habitat, complexidade estrutural, riachos.
