Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

Insect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Integrative taxonomy reveals four new species of the armoured catfish genus Pareiorhina (Siluriformes: Loricariidae) from the upper Paraná River basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Four new species of the small‐sized armoured catfish genus Pareiorhina are described from mountain ranges in the Grande River drainage, upper Paraná River basin, based on morphological and molecular species delimitation methods. Molecular analyses based on the cytochrome oxidase subunit I (COI) marker recovered Pareiorhina as polyphyletic ...

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Periphyton and Benthic Macroinvertebrate Response to Antimycin Piscicide During Brook Trout Restoration

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT The piscicide antimycin has been used as an effective fish toxicant to eradicate nuisance fishes because it is not as detectable by fish as other chemical piscicides. We evaluated the effects of antimycin and its detoxicant, potassium permanganate, on periphyton and benthic macroinvertebrates during a brook trout (Salvelinus fontinalis ...

Biogeographic regionalization of Odonata (Insecta) in the Neotropics: contrasting Anisoptera and Zygoptera spatial patterns [PDF]

Frontiers of Biogeography
The Neotropical region stands as a significant hotspot for Odonata diversity, yet comprehensive spatial patterns have remained less elucidated. This study aimed to provide a comprehensive biogeographical regionalization of the order Odonata across the ...

\u3ci\u3eNeurocordulia (Platycordulia) Xanthosoma\u3c/i\u3e (Williamson) in Texas (Odonata: Libellulidae: Corduliinae) [PDF]

, 2017
(excerpt) The rarity of a species is usually judged by the number of specimens in collections, both private and institutional, and the number of places where it has been found or seen. On this basis, Neurocordulia xanthosoma (Williamson) is rare.

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

Ecological Entomology, Volume 51, Issue 2, Page 235-249, April 2026.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...
