Lagos como sensores de cambio climático: el caso de La Alberca de Tacámbaro, Michoacán, México

open access: yesTIP Revista Especializada en Ciencias Químico-Biológicas, 2019
Los lagos están entre los ecosistemas más sensibles al cambio climático, ya que el comportamiento termodinámico de su columna de agua es controlado por la marcha anual de la temperatura.

Seascape Genomics Uncovers Genomic Patterns Shaped by Temperature and Salinity Outlier Loci in Dolphinfish (Coryphaena hippurus Linnaeus, 1758) Across the Atlantic Ocean and Mediterranean Sea

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT In this study, we explored the population genetic structure and its relation to environmental adaptations of the dolphinfish (Coryphaena hippurus) in the western Atlantic Ocean and Mediterranean Sea. Although previously two populations within the Mediterranean Sea were identified, recent evidence suggests more complex structuring.

Crustacean zooplankton species richness in Chilean lakes and ponds (23°-51°S)

open access: yesLatin American Journal of Aquatic Research, 2013
Chilean inland-water ecosystems are characterized by their low species-level biodiversity. This study analyses available data on surface area, maximum depth, conductivity, chlorophyll-α concentration, and zooplankton crustacean species number in lakes ...

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

How Management Practices Shape the “Local Habitat Signature” That Modulates Bird Communities in Urban Green Spaces

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Local scale factors, not just the broad urban gradient, are the key drivers of urban bird communities. Our multi‐scale study found that specific management practices, such as managing leaf litter depth or the presence of unmanaged tall grass, explained the largest portion of variation in bird composition.

Multiple Threats Have Overlapping Impacts Across Ecological Levels in Freshwater Ecosystems

open access: yesFreshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Changes driven by climate change, biological invasion, land‐use change, pollution and overexploitation are decreasing the resilience of freshwater ecosystems worldwide. While the impact of these threats is widely recognised, a critical gap remains in systematically quantifying their relative effects across ecological levels, which is essential

Anthropogenic Barriers Limit Fish Access to Essential Habitats in the Amazon in the Face of Climate Change

open access: yesGlobal Change Biology, Volume 32, Issue 1, January 2026.
Rivers across the Amazon Basin are increasingly threatened by climate change and dam construction, which restrict fish movements. We combined climate projections with river‐network connectivity analyses to identify where suitable habitats for frugivorous and socioeconomically important fish are likely to persist and where access may be lost due to ...
