Predators reduce extinction risk in noisy metapopulations [PDF]
, 2010 Background Spatial structure across fragmented landscapes can enhance regional population persistence by promoting local “rescue effects.” In small, vulnerable populations, where chance or random events between individuals may have disproportionately ...

Strongly deleterious mutations are a primary determinant of extinction risk due to inbreeding depression [PDF]
bioRxiv, 2020 Human-driven habitat fragmentation and loss have led to a proliferation of small and isolated plant and animal populations with high risk of extinction.

Planning for megafauna recovery in the tropical rainforests of Sumatra
Frontiers in Ecology and Evolution, 2023 Human-induced forest loss has had devastating impacts on biodiversity. Mammal populations in the tropics have been hit particularly hard by the resulting habitat loss, fragmentation and degradation, as well as by overhunting which often goes hand-in-hand.

Extinction Risk Assessment of the Greek Endemic Flora
Biology, 2021 Simple Summary This study assesses for the first time all the vascular endemic plant taxa of Greece, according to their decline and rarity. Phylogenetic analysis and its spatial overview highlight areas for conservation prioritization.

Multispecies approaches to status assessments in support of endangered species classifications
Conservation Science and Practice, 2022 Multispecies risk assessments have developed within many international conservation programs, reflecting a widespread need for efficiency. Under the United States Endangered Species Act (ESA), multispecies assessments ultimately lead to species‐level ...

Survival of small populations under demographic stochasticity [PDF]
, 1992 We estimate the mean time to extinction of small populations in an environment with constant carrying capacity but under stochastic demography. In particular, we investigate the interaction of stochastic variation in fecundity and sex ratio under several

Drivers of local extinction risk in alpine plants under warming climate.
Ecology Letters, 2021 The scarcity of local plant extinctions following recent climate change has been explained by demographic inertia and lags in the displacement of resident species by novel species, generating an 'extinction debt'.

Hurst Coefficient in long time series of population size: Model for two plant populations with different reproductive strategies [PDF]
, 2010 Can the fractal dimension of fluctuations in population size be used to estimate extinction risk? The problem with estimating this fractal dimension is that the lengths of the time series are usually too short for conclusive results.

Conservation status, threats, and information needs of small mammals in Alaska
Conservation Science and Practice, 2022 Small mammals are under‐represented in conservation research relative to other mammals. We assessed the conservation status of 36 small mammal species in Alaska, USA using the Alaska Species Ranking System (ASRS).
