Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

Ibis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

Integrative taxonomy reveals two new species of whiptail catfishes Loricaria (Siluriformes: Loricariidae) from northeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract Two new species of whiptail catfish, Loricaria (Siluriformes: Loricariidae), were discovered in the Munim and Itapecuru river basins, Maranhão State, northeastern Brazil, through an integrative taxonomic approach combining morphology and mitochondrial DNA.

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 ...

Ecophysiological study of green microalgae isolated from the grit crust of the Atacama Desert

Journal of Phycology, EarlyView.
Abstract Terrestrial algae play a critical, yet often overlooked, role in the functioning of biological soil crusts (biocrusts), which are considered microecosystems, particularly in extreme environments. This study investigated the ecophysiological traits of green algae isolated from the grit crust—a unique biocrust type reported a few years ago in ...
