Patterns of protist distribution and diversification in alpine lakes across Europe. [PDF]
Microbiologyopen, 2021 Deviations of high‐mountain protist communities from lowland communities are well known but the underlying diversification processes are hardly understood. Here, we studied protist communities in several European high‐mountain ranges and analyzed commonalities and deviations between these sites.

Effects of spatial distance and woody plant cover on beta diversity point to dispersal limitation as a driver of community assembly during postfire succession in a Mediterranean shrubland. [PDF]
Ecol Evol, 2022 In this work we analyze how beta diversity, and its components of turnover and nestedness, change in a herbaceous plant community during the first years following fire, and how they relate to spatial distance and the effect of woody plant cover. We found that dispersal limitation, indicated by an increase in similarity with spatial distance, is the ...

Tracing species replacement in Iberian marbled newts. [PDF]
Ecol Evol, 2021 Hybrid zone movement has been suggested in the marbled newts, supported by the discovery of a Triturus marmoratus enclave. Here, we tested for a genomic footprint of species replacement of the receding T. marmoratus by the advancing T. pygmaeus, employing 54 newly developed nuclear SNPs and one mitochondrial DNA marker. In the absence of genetic traces

Diversity and Distributions, Volume 28, Issue 1, Page 4-24, January 2022., 2022 Abstract Aim Holm oak (Quercus ilex L.) is regarded as a keystone plant species. Trophic interactions may affect the distribution and abundance of phytophagous species, but the number of arthropod species that use holm oak as a food resource and their levels of host specificity are not yet known.

Water Resources Research, Volume 57, Issue 11, November 2021., 2021 Abstract Impact of hydrology‐associated deformation spans from the study of the rock hydrological properties and aquifer dynamics to the identification of geological disaster precursors. We analyze a comprehensive set of hydrology‐associated deformation signals, recorded by two underground 70 m long strainmeters (GAL16 and LAB780) operating under the ...

Journal of Fish Biology, Volume 99, Issue 4, Page 1158-1189, October 2021., 2021 ABSTRACT Freshwater fish communities in Ecuador exhibit some of the highest levels of diversity and endemism in the Neotropics. Unfortunately, aquatic ecosystems in the country are under serious threat and conditions are deteriorating. In 2018–19, the government of Ecuador sponsored a series of workshops to examine the conservation status of Ecuador's ...

Factors shaping community patterns of protists and bacteria on a European scale
Environmental Microbiology, Volume 22, Issue 6, Page 2243-2260, June 2020., 2020 Summary Factors shaping community patterns of microorganisms are controversially discussed. Physical and chemical factors certainly limit the survival of individual taxa and maintenance of diversity. In recent years, a contribution of geographic distance and dispersal barriers to distribution patterns of protists and bacteria has been demonstrated ...

Ecosphere, Volume 11, Issue 5, May 2020., 2020 Abstract Evidence is accumulating of the disruptive effects of climate change on species interactions. However, little is known about how changes in climate patterns, such as temporal shifts in rainfall events, will affect multitrophic interactions.

Hidroelectricidad, embalses y cambio climático
Ingeniería del agua, 2009 [ES] La energía hidroeléctrica, los embalses y el cambio climático, mantienen unas relaciones con distintos sentidos. La hidroelectricidad requiere embalses y estos producen gases con efecto invernadero. Para frenar el cabio climático, se promueven energías renovables y la hidroelectricidad lo es.
