Checklist of the marine Bryozoa from Uruguay (Southwest Atlantic)

Revista del Museo Argentino de Ciencias Naturales, 2022
Knowledge of the marine bryozoan fauna of Uruguay is mostly based on scattered records found in local faunistic surveys and the taxonomic results of two oceanographic cruises to the Southwest Atlantic, but a comprehensive study has not yet been published for this area. This paper aims to compile an updated checklist, bringing together all the published

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

Chemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Dramatic ENSO related Southwestern Atlantic ecosystem shifts

Scientific Reports
ENSO (El Niño Southern Oscillation) events are becoming more frequent and more intense as climate change continues. Although ENSO effects are known to propagate into the southwest Atlantic, knowledge of how these anomalies result in ecological impacts is

Reduced size of larvae and small fish linked to warming and reduced prey density

Ecography, EarlyView.
Body size is an integrative trait that has declined across many ecological assemblages in the last decades. Changes in body size of early life stages and small‐bodied fish are driven by complex interactions between size‐dependent mortality, and temperature‐ and food‐dependent growth, and can have consequences for recruitment to the adult stock and food

Spatially heterogenous range dynamics since the Last Glacial Maximum underpin the modern bimodal latitudinal diversity gradient in planktonic foraminifera

Ecography, EarlyView.
The modern latitudinal diversity gradient (LDG) of planktonic foraminifera is bimodal, with a distinct depression near the equator surrounded by mid‐latitude diversity peaks. This pattern emerged after the Last Glacial Maximum (LGM; 19–23 ka), but it remains unclear how species' spatial dynamics contributed to its formation.

Distribution and reproductive biology of the Electric ray Discopyge tschudii Heckel, 1846 in San Matías Gulf, Northern Patagonia, Argentina

Neotropical Ichthyology
The Electric ray Discopyge tschudii is distributed in the Southwest Atlantic from southern Brazil to southern Argentina and in the Southeast Pacific from Peru to southern Chile. The main threat to this species is fishing.
