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.

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.

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

Digging the pupfish out of its hole: risk analyses to guide harvest of Devils Hole pupfish for captive breeding. [PDF]
, 2014 The Devils Hole pupfish is restricted to one wild population in a single aquifer-fed thermal pool in the Desert National Wildlife Refuge Complex. Since 1995 the pupfish has been in a nearly steady decline, where it was perched on the brink of extinction ...

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 ...

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).

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.

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 ...

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 ...
