Assigning trend‐based conservation status despite high uncertainty

Conservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract Estimates of temporal trends in species’ occupancy are essential for conservation policy and planning, but limitations to the data and models often result in very high trend uncertainty. A critical source of uncertainty that degrades scientific credibility is that caused by disagreement among studies or models.

Does the loss of diadromy imply the loss of salinity tolerance? A gene expression study with replicate nondiadromous populations of Galaxias maculatus

Molecular Ecology, Volume 32, Issue 9, Page 2219-2233, May 2023., 2023
Abstract The recurrent colonization of freshwater habitats and subsequent loss of diadromy is a major ecological transition that has been reported in many ancestrally diadromous fishes. Such residency is often accompanied by a loss of tolerance to seawater.

Evident but context‐dependent mortality of fish passing hydroelectric turbines

Conservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Globally, policies aiming for conservation of species, free‐flowing rivers, and promotion of hydroelectricity as renewable energy and as a means to decarbonize energy systems generate trade‐offs between protecting freshwater fauna and development of hydropower. Hydroelectric turbines put fish at risk of severe injury during passage. Therefore,

Alarming decline of freshwater trigger species in western Mediterranean key biodiversity areas

Conservation Biology, Volume 35, Issue 5, Page 1367-1379, October 2021., 2021
Abstract Theidentification of key biodiversity areas (KBA) was initiated by the International Union for Conservation of Nature in 2004 to overcome taxonomic biases in the selection of important areas for conservation, including freshwater ecosystems.

Combined effects of life‐history traits and human impact on extinction risk of freshwater megafauna

Conservation Biology, Volume 35, Issue 2, Page 643-653, April 2021., 2021
Abstract Megafauna species are intrinsically vulnerable to human impact. Freshwater megafauna (i.e., freshwater animals ≥30 kg, including fishes, mammals, reptiles, and amphibians) are subject to intensive and increasing threats. Thirty‐four species are listed as critically endangered on the International Union for Conservation of Nature (IUCN).
