Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change

open access: yesGlobal Change Biology, Volume 30, Issue 7, July 2024.
This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...

High methane concentrations in tidal salt marsh soils: Where does the methane go?

open access: yesGlobal Change Biology, Volume 30, Issue 1, January 2024.
Salt marsh soils can contain high concentrations of methane, but what happens to this gas? There are a few possibilities, including vertical and lateral transport, storage within the soil, and/or oxidation resulting in transport as carbon dioxide or dissolved inorganic carbon.

Salinidad y germinación de ecotipos de Melilotus Segetalis

open access: yesPastos, 1992
[EN]: Salinity induces a retardation in the speed of germination and a reduction in the number of seeds germinated. In this paper we compare the response to different NaCl levéis, during the germination stage, among Melilotus segetalis populations from con- trasted habitats.
