One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

There is no relationship between the demographic susceptibility to extinction and the estimated extinction chronology among Sahul’s megafauna, suggesting that human choices, a species’ ecological requirements, and/or random climate variation instead determined the extinction chronology.

Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.

Application of museomics facilitates characterization of the contribution of historical factors to genetic diversity declines in Numenius shorebirds and highlights that extinction of ecosystem-engineering megafauna may have been detrimental for open-landscape species.

Almost 98% of amphibian species have no regulation on their international trade, yet as 17% (1215 species) are in trade with 45% of individuals coming from the wild, including 445 Endangered/Data Deficient species, this poses a risk to species survival.

Population mutation rates are highly flexible and evolvable under extreme stress conditions, matching changes in selective pressure to avoid extinction of the entire population.

A combination of electrophysiological and optogenetic approaches revealed a causal role for glutamatergic neurons in the prelimbic cortex in regulating individual differences in decision-making strategies during a threat-avoidance vs. reward-approach conflict paradigm in rats.

A smart combination of machine learning and high-throughput data generation of bacterial population dynamics successfully leads to an intriguing finding of the differentiation in decision-making components for bacterial growth.
