Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

Journal of Fish Biology, EarlyView.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...

A new species of inseminating catfish of the genus Tympanopleura (Siluriformes: Auchenipteridae) from the Ituxi River, Amazon River basin, northern Brazil, revealed by integrative taxonomy

Journal of Fish Biology, EarlyView.
Abstract A new species of the genus Tympanopleura is described from the Iquiri River, a tributary of the Ituxi River, a right‐bank tributary to the Purus River, Amazon River, northern Brazil. The new species is distinguished from all its congeners by a combination of features, such as the presence of an intensely pigmented square‐shaped blotch on the ...

A new sexually dimorphic species of the armoured catfish genus Neoplecostomus (Siluriformes: Loricariidae) from Neotropical Atlantic coastal drainages

Journal of Fish Biology, EarlyView.
Abstract A new species of the small‐sized armoured catfish genus Neoplecostomus is described from Neotropical Atlantic coastal drainages, in southeast Brazil. The new species can be readily diagnosed from all congeners by having the first plates of the ventral series reduced in size, rounded and ventrally displaced, resulting in a naked band between ...

Social roles and resource competition mediate intraspecific interactions of Chilean Flamingo (Phoenicopterus chilensis) in southern Brazil

Journal of Zoology, EarlyView.
In social birds such as flamingos, intraspecific interactions are frequent and play a key role in flock cohesion, communication, and the establishment of social networks. Understanding the patterns and drivers of these interactions can provide valuable ecological insights and inform management, husbandry, and conservation practices.

Sclerophyllous structural and chemical traits of mite‐induced galls on Crinodendron patagua (Elaeocarpaceae) leaves

Plant Biology, EarlyView.
Eriophyid mites reprogram the structural and biochemical traits of sclerophyllous leaves in Crinodendron patagua, promoting the formation of nutrient‐rich and protective gall tissues. Abstract Sclerophyllous plants present a suite of traits, including small, leathery leaves with thick cuticles, dense trichomes and sclerified tissues, which are often ...
