Effects of climate change on marine biodiversity on the western Atlantic coast

Conservation Biology, EarlyView.
Abstract The current climate crisis, driven by greenhouse gas emissions, threatens global biodiversity, including that in marine ecosystems. However, projections for the western Atlantic Ocean that jointly quantify species richness and endemism while accounting for spatially biased and incomplete occurrence data remain limited.

Species inventory of aquatic macrophytes in the last undammed stretch of the Upper Paraná River, Brazil

Acta Limnologica Brasiliensia, 2017
The last undammed stretch of the Upper Paraná River in the Brazilian territory is, to date, not completely inventoried, which rises concerns given the rapid rates of species extinctions.

Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

Fisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

Diagnosis and Off‐Label Treatment of Subcutaneous Putative Dracunculoid Nematodes in Apteronotus albifrons Originating From Wild‐Caught Fisheries

Journal of Fish Diseases, EarlyView.
ABSTRACT Apteronotus albifrons (Gymnotiformes: Apteronotidae), commonly known as the black ghost knifefish, is a high‐value ornamental fish that is susceptible to various parasites. The affected fish were wild‐caught fisheries and subsequently introduced into a commercial breeding system.

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

Journal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.
