Extinction risk in vascular plants and vertebrates is negatively correlated with family size
Global Ecology and Conservation, 2021 Understanding the pattern of species extinction risk is key to biodiversity conservation. Previous studies showed extinction risk correlates strongly with taxon species richness. However, there is no consistent conclusion to this hypothesis, and patterns

Human population density and extinction risk in the world's carnivores. [PDF]
PLoS Biology, 2004 Understanding why some species are at high risk of extinction, while others remain relatively safe, is central to the development of a predictive conservation science.

Effect of compositional fluctuation on the survival of bet-hedging species [PDF]
arXiv, 2022 Understanding the coexistence of diverse species in a changing environment is an important problem in community ecology. Bet-hedging is a strategy that helps species survive in such changing environments. However, studies of bet-hedging have often focused on the expected long-term growth rate of the species by itself, neglecting competition with other ...

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.

Democratising Risk: In Search of a Methodology to Study Existential Risk [PDF]
arXiv, 2021 Studying potential global catastrophes is vital. The high stakes of existential risk studies (ERS) necessitate serious scrutiny and self-reflection. We argue that existing approaches to studying existential risk are not yet fit for purpose, and perhaps even run the risk of increasing harm.

Geography of current and future global mammal extinction risk. [PDF]
PLoS ONE, 2017 Identifying which species are at greatest risk, what makes them vulnerable, and where they are distributed are central goals for conservation science. While knowledge of which factors influence extinction risk is increasingly available for some taxonomic

Evaluating The Impact Of Species Specialisation On Ecological Network Robustness Using Analytic Methods [PDF]
arXiv, 2023 Ecological networks describe the interactions between different species, informing us of how they rely on one another for food, pollination and survival. If a species in an ecosystem is under threat of extinction, it can affect other species in the system and possibly result in their secondary extinction as well. Understanding how (primary) extinctions

Bushmeat hunting and extinction risk to the world's mammals [PDF]
Royal Society Open Science, 2016 Terrestrial mammals are experiencing a massive collapse in their population sizes and geographical ranges around the world, but many of the drivers, patterns and consequences of this decline remain poorly understood. Here we provide an analysis showing that bushmeat hunting for mostly food and medicinal products is driving a global crisis whereby 301 ...

Predicting evolutionary rescue via evolving plasticity in stochastic environments [PDF]
Proc. R. Soc. B 283:20161690 (2016), 2016 Phenotypic plasticity and its evolution may help evolutionary rescue in a novel and stressful environment, especially if environmental novelty reveals cryptic genetic variation that enables the evolution of increased plasticity. However, the environmental stochasticity ubiquitous in natural systems may alter these predictions because high plasticity ...

Red-list of moss species of Serbia: 2024 assessment [PDF]
Botanica SerbicaThe new extinction risk assessments of the mosses of Serbia have been completed. Based on the available data, 27.18% of Serbian moss flora (174 species) is under threat (status 2024).
