Identifying hotspots of faunal data deficiency to direct urgent research and monitoring. [PDF]

open access: yesConserv Biol
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Mapping area of habitat for inland wetland species. [PDF]

open access: yesConserv Biol
Abstract Area of habitat (AOH) maps provide a high‐resolution representation of the habitat available in a species’ range and can support conservation policy and planning processes. However, until recently, there was insufficient knowledge on the distribution of inland wetlands and freshwater biodiversity to develop AOH mapping methods specifically ...

Assigning trend‐based conservation status despite high uncertainty

open access: yesConservation 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

open access: yesMolecular 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

open access: yesConservation 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,
