Towards a model of postglacial biogeography in shallow marine species along the Patagonian Province: lessons from the limpet Nacella magellanica (Gmelin, 1791)

open access: yesBMC Evolutionary Biology, 2012
Background Patagonia extends for more than 84,000 km of irregular coasts is an area especially apt to evaluate how historic and contemporary processes influence the distribution and connectivity of shallow marine benthic organisms.

Two New Clathria Schmidt, 1862 (Porifera: Microcionidae) From Rhodolith Beds in the Southwest Atlantic, Brazil

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
Rhodolith beds are structurally complex biogenic habitats recognized as important reservoirs of marine biodiversity, yet their associated sponge fauna remains poorly documented in the Southwestern Atlantic. Here, two new species of the genus Clathria Schmidt, 1862 (Microcionidae) are described from mesophotic rhodolith beds off the coast of Pernambuco,

Open letter: The need for a site‐based biodiversity standard measuring and certifying impacts from nature‐based projects

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1394-1402, September 2026.
Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.

Fecundity and spawning of Abralia verany (Rüppell, 1844) (Cephalopoda: Enoploteuthidae) in the Aegean Sea

open access: yesScientia Marina, 2005
A total of 24 female Abralia verany specimens, with a mantle length between 26-47 mm, were investigated. The mean potential fecundity (PF) and mean relative fecundity (RF) of ovaries were calculated as 26584 eggs and 4379 eggs g-1, respectively. The mean

Reconstructing Along‐Strike Variability of Retreating Accretionary Margins Using Detrital Isotopic Proxies in Patagonia and Japan

open access: yesTectonics, Volume 45, Issue 9, September 2026.
Abstract Retreating accretionary systems are common features of convergent plate margins. They are characterized by upper plate extension and backarc basin formation, which often forms diachronously and asymmetrically along‐strike. This study tests the hypothesis that this along‐strike variability in backarc basin formation is reflected in detrital and

Analytical and Laboratory Investigation of Groundwater Pumping in Strip Island Aquifers With Single‐Sided Land Reclamation

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Land reclamation has been widely implemented on oceanic islands to alleviate land scarcity. Previous studies of groundwater pumping in reclaimed island aquifers have primarily considered symmetric reclamation and fixed well placement. Here, we extend this framework to an asymmetric strip island aquifer with single‐sided low‐permeability ...

Movements and behaviour of southern right whales satellite-tracked in and beyond a subantarctic archipelago wintering ground

open access: yesEndangered Species Research
The post-exploitation recovery of the south-west Atlantic southern right whale (SRW, Eubalaena australis) population has been affected by widespread calf mortalities, resulting in the development of an International Whaling Commission Conservation ...

Penguins of the Magellan region

open access: yesScientia Marina, 1999
The Magellan region, including the Falkland Islands, is one of the world´s most important areas for seabirds, and especially penguins. World-wide there are 17 species of penguin; 7 of these regularly breed around the coastal waters of South America, and ...
