Purpose: Investigate the influence of environmental variables and spatial autocorrelation on aquatic insect communities within the same water flow in Atlantic Forest streams. Theoretical framework: The organisms in lotic environments are influenced by both local and non-local factors, in addition to other processes, which result from the dynamics o...

In caridean shrimps, sexual systems vary from gonochorism to various forms of hermaphroditism. The shrimp Salmoneus carvachoi has been reported to exhibit both male (appendix masculina) and female (brooding embryos) anatomical characteristics simultaneously. Our aim was to examine the sexual system of S. carvachoi and to test the hypothesis of prot...

Graphical abstract Highlights d Ecological metadata were compiled for 7,694 sites across the Brazilian Amazon d Accessibility and proximity to research facilities influenced research probability d Knowledge gaps are greater in uplands than in wetlands and aquatic habitats d Undersampled areas overlap predicted hotspots of climate change and defores...

Family Corethrellidae has a worldwide distribution with most known extant species occurring in the Neotropics, many with only the adult stages described. Despite previous efforts, one remaining problem in the taxonomy of Corethrellidae is the challenge of delimiting species due to the current range of morphological characters included in descriptio...

Environmental changes are increasingly frequent, resulting in adverse impacts on biodiversity. These effects are more harmful when superimposed on areas of high biodiversity such as the Amazon region, in which the gaps in knowledge of the number of existing species and how they are distributed. This article reviews the known geographical distributi...

Prof. Dr. Claudio Gilberto Froehlich’s career is presented here using numbers and actions guided by a genuine way to study biodiversity, especially aquatic ecosystems. An extensive number of publications is accompanied by an investment in human resources training and establishing a vast network of collaborators and friendships. Dr. Peter Zwick ment...

The limited knowledge of biodiversity constrains conservation strategies in a wide range of questions. Overcoming and recognizing these knowledge deficits require integrated efforts by current researchers and constitute crucial challenges for the next generations. Prof. Dr. Claudio Froehlich was a pioneer in implementing a research program integrat...

Campsurus is the most species-rich genus in Polymitarcyidae, and it is divided into four groups. A new species is described and illustrated here based on male imagos. Campsurus molinerii sp. nov. seems to be similar to C. nessimiani, C. dasilvai, and C. cuyuniensis because of the shape of penes and pedestal. The new species differs from them by the...

A conservação tem como um dos seus principais objetivos a manutenção da biodiversidade. As métricas para medir a biodiversidade em uma determinada área, dependem da interação de vários fatores, como por exemplo a relação de dados bióticos com dados abióticos do ambiente nos organismos. A proposta deste trabalho é fazer um levantamento faunístico fo...

Hagenulopsis diptera Ulmer, type species of the genus Hagenulopsis, was originally described based on imagos from Santa Catarina State, Southern Brazil. Misconceptions of H. diptera circumscription led to erroneous attribution of material from Minas Gerais and Espírito Santo, Southeastern Brazil, to H. diptera. Despite the increase in the number of...

Introdução: A conservação tem como um dos seus principais objetivos a manutenção da biodiversidade. As métricas para medir a biodiversidade em uma determinada área, dependem da interação de vários fatores, como por exemplo a relação de dados bióticos (como grupos taxonômicos) com dados abióticos (informações sobre o clima ou vegetação), sendo possí...

Understanding the diet of tadpoles is fundamental to explain their ecological roles in aquatic food webs, as well as to allow more effective amphibian conservation and management programs. Studies on trophic ecology of tadpoles are scarce compared to other vertebrate groups, a gap that is even more accentuated in the Neotropical region, which harbo...

The genus Leptagrion Selys, 1876 comprises 17 described species. Of these species, only eight have their immature stage described.

In the present work, we provide the description of a new species to the genus based...

A new species of Bessierus Thomas & Orth, formerly a monotypic genus, is described from Amapá State, Brazil. The type species of the genus, B. doloris Thomas & Orth, had only its nymphs described until recently, when its male imago was associated to nymphs mainly based on pigmentation pattern. Bessierus riobranco sp. n. here described has no signif...

Protecting riparian vegetation around streams is vital in reducing the detrimental effects of environmental change on freshwater ecosystems and in maintaining aquatic biodiversity. Thus, identifying ecological thresholds is useful for defining regulatory limits and for guiding the management of riparian zones towards the conservation of freshwater...

There is a strong link between habitat loss, fragmentation of natural vegetation, and reduction of biodiversity in aquatic systems. The objective of this study was to evaluate the influence of different landscape scales on the community of Ephemeroptera, Plecoptera, and Trichoptera in Atlantic Forest rivers. We sought to understand how aquatic comm...

Askola Peters is a two-winged South American genus of Atalophlebiinae (Leptophlebiidae) and currently comprises five known species primarily described based on male imagos characters, while data from female and immature stages are scarce and often unknown. Herein, Askola was revised under cladistic approach for the first time in order to test the m...

In the present study we used larval amphibians (Rhinella jimi) as prey, and beetle larvae (Hydrophilus sp.) as predator to assess if increased water temperature influences predator-prey dynamics. The experiment was carried out in replicated aquatic microcosms with two different water temperatures (control and a ‘warming water’ scenario). Survival o...

Gynandromorphism or intersexuality is a rare condition where the individual has male and female features. In this report we described two imagoes of Farrodes xingu Domínguez et al. (1996) from Brazil presenting intersex traits. We considered the arranged sexual characters as antero-posterior and bilateral. One individual has a male head, abdomen fu...

Studies on fecundity and embryo size have been frequently used to infer about the reproductive potential, embryo-genesis, and the energy investment in embryo production in crustaceans. These parameters are relevant to the knowledge of life-history and diversity of reproductive strategies developed by this group. This study addressed the embryo prod...
