The effects of Bacillus thuringiensis var. israelensis (Bti) on tropical stream food webs vary between two consecutive dry seasons

open access: yesInsect Conservation and Diversity, EarlyView.
Bti application altered tropical stream food‐web structure through changes in macroinvertebrate functional feeding groups. Collector‐filterers and predators showed context‐dependent responses, with clearer direct and indirect effects detected in 2016, the year with higher rainfall.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

open access: yesInsect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.

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

open access: yesJournal 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

open access: yesJournal 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 ...
