First record of the “Matrinxã” Brycon amazonicus (Agassiz 1829) (Characiformes: Bryconidae) in the Rio Paranapanema mouth region, Upper Rio Paraná basin, Brazil [PDF]

Acta Limnologica Brasiliensia
: The Rio Paranapanema is one of the most important tributaries of the Upper Rio Paraná, and in recent decades there has been a marked decline in the population of native species due to the development of a series of reservoirs and the introduction of ...

Estimating IUCN Red List population reduction: JARA—A decision‐support tool applied to pelagic sharks

Conservation Letters, 2020
The International Union for Conservation of Nature's (IUCN) Red List is the global standard for quantifying extinction risk but assessing population reduction (criterion A) of wide‐ranging, long‐lived marine taxa remains difficult and controversial.

Imperfect detection biases extinction‐debt assessments

Conservation Science and Practice, 2021
Freshwater ecosystems have been substantially altered, threatening the survival and recovery of aquatic species at risk. Estimating the likelihood and magnitude of future extinctions (extinction debt; ED) is integral for conserving biodiversity and ...

How predictable are mass extinction events?

Royal Society Open Science, 2023
Many modern extinction drivers are shared with past mass extinction events, such as rapid climate warming, habitat loss, pollution and invasive species.

Relative Importance of Ecological, Evolutionary and Anthropogenic Pressures on Extinction Risk in Chinese Angiosperm Genera

Frontiers in Ecology and Evolution, 2022
China has many threatened plant species, which are exposed to environmental degradation and other anthropogenic pressures. We assessed support for potential extinction pathways in Chinese angiosperm genera and quantified possible threats to phylogenetic ...

Ecological and Conservation Correlates of Rarity in New World Pitvipers

Diversity, 2019
Rare species tend to be especially sensitive to habitat disturbance, making them important conservation targets. Thus, rarity patterns might be an important guide to conservation efforts.

Chemical antipredator defence is linked to higher extinction risk [PDF]

Royal Society Open Science, 2016
Many attributes of species may be linked to contemporary extinction risk, though some such traits remain untested despite suggestions that they may be important.

A comprehensive quantitative assessment of bird extinction risk in Brazil. [PDF]

PLoS ONE, 2013
In an effort to avoid species loss, scientists have focused their efforts on the mechanisms making some species more prone to extinction than others. However, species show different responses to threats given their evolutionary history, behavior, and ...

Increasing environmental fluctuations can dampen variability of endogenously cycling populations

Royal Society Open Science
Understanding how populations respond to increasingly variable conditions is a major objective for natural resource managers forecasting extinction risk.
