Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm. [PDF]

Glob Chang Biol
How ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...

Multigene phylogenetics of Sargassum (Phaeophyceae) revealed low molecular diversity in contrast to high morphological variability in the NE Atlantic Ocean. [PDF]

J Phycol
Abstract Sargassum species play a key role in habitat formation in tropical and subtropical regions; however, species identification has been hampered by the phenological plasticity exhibited in response to environmental conditions and life history. Molecular phylogenetics has challenged taxa circumscriptions and proven critical in delimiting species ...

Using long‐term data series to design adequate protected areas that ensure the conservation of inconspicuous small petrel species

Journal of Applied Ecology, Volume 60, Issue 12, Page 2586-2601, December 2023., 2023
Our study highlights the importance of analysing long time series and ESDMs to design adequate protected areas, which ensure the conservation of small and highly mobile species such as storm petrels. Our results should be considered by decision‐makers to prioritise and update marine protected areas, while incorporating the dynamic nature of the ocean ...

Repeated asynchronous evolution of single‐species endemics of ivies (Hedera L.) in Macaronesian archipelagos

Journal of Biogeography, Volume 50, Issue 10, Page 1763-1777, October 2023., 2023
Abstract Aim Evolutionary studies of oceanic island endemics are usually focused on lineages that have experienced in situ radiation, while those that speciated once on the island or archipelago but have not further diversified (single‐species endemics) remain understudied.

Tracking marine tetrapod carcasses using a low‐cost mixed methodology with GPS trackers, passive drifters and citizen science

Methods in Ecology and Evolution, Volume 14, Issue 9, Page 2354-2361, September 2023., 2023
Abstract Drift experiments are essential to understand stranding patterns and estimate the mortality of beached animals. Most studies do not use telemetry technology due to the high costs of this methodology. The objective of this paper is to describe the possibilities of tracking marine tetrapod carcasses with a low‐cost and replicable methodology ...
