Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The Iberian killer whale subpopulation was assessed as critically endangered (CR) by the IUCN red list of threatened species based on the available information until 2011 on its low abundance, high newborn mortality, and dependency on the endangered Atlantic bluefin tuna.

Anthropogenic or Natural Dispersal: Case of the Spiny‐Tailed Iguanas (Ctenosaura) on Clarion Island, Mexico

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Species can colonize oceanic islands by both natural and human‐assisted dispersal and human‐caused species introductions have had catastrophic effects on ecosystems around the world. The Spiny‐tailed Iguanas inhabiting Clarion Island were previously considered introduced. Molecular data and analyses support iguanas' arrival on Clarion Island by natural

Comparing Cloud Mask Products for Seagrass Mapping Over Sentinel‐2 Imagery: Toward a First National Seagrass Map for Venezuela

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract Despite providing many valuable ecosystem services, seagrasses are a threatened habitat and their global distribution is not fully known. For example, Venezuela lacks a national seagrass map. An established regional mapping approach for seagrass exists for the Google Earth Engine (GEE) platform, but requires a long time window to obtain ...

Scaling up ocean conservation through recognition of key biodiversity areas in the Southern Ocean from multispecies tracking data

Conservation Biology, Volume 39, Issue 1, February 2025.
Abstract Biodiversity is critical for maintaining ecosystem function but is threatened by increasing anthropogenic pressures. In the Southern Ocean, a highly biologically productive region containing many endemic species, proactive management is urgently needed to mitigate increasing pressures from fishing, climate change, and tourism.

Range Extension of the Popeye Catalufa (Pristigenys serrula, Gilbert 1891) to Central Chile During the “El Niño” Southern Oscillation (ENSO) 2023–2024

Ecology and Evolution, Volume 14, Issue 12, December 2024.
Phylogenetic and morphological analyses confirm P. serrula in central Chile (32° S). The geographical distribution of P. serrula in central Chile extends 9° southward. This extension is associated with the “El Niño” Southern Oscillation (ENSO). ABSTRACT We report the presence of Pristigenys serrula Gilbert 1891 off Zapallar (−32.568253, −71.464225 ...

Isla del Fraile. Reconstructing Coastal Dynamics in Southeastern Spain Through Underwater Archaeological Survey

Archaeological Prospection, Volume 31, Issue 2, Page 149-170, April/June 2024.
ABSTRACT A new archaeological research project analyses the history of Isla del Fraile (Águilas, Spain), a small island off the coast occupied since at least Roman times. Its isolation means that the sea has always conditioned its connectivity and relationship with land.
