Evolution, Extinction, and Extinction Rate Estimates of the World Squirrels
Beyond Charles Darwnin, the taxonomy and subsequent phylogeny of squirrels, their biogeography, and their evolution explicit in time and space remain...

Diversity-dependent speciation and extinction in hominins
The search for drivers of hominin speciation and extinction has tended to focus on the impact of climate change. Far less attention has been paid to...
-
Population Models of Extinction
In the previous chapter we discussed the basics of population dynamics, whose models describe the average population size, which changes over time....

Extinction drives recent thermophilization but does not trigger homogenization in forest understorey
The ongoing climate change is triggering plant community thermophilization. This selection process ought to shift community composition towards...

Introduction to the Language of Extinction
The way conservationists represent extinction today is found predominantly in talk of ‘populations.’ The details of individual life are not necessary...

A history of avoidance does not impact extinction learning in male rats
Pervasive avoidance is one of the central symptoms of all anxiety-related disorders. In treatment, avoidance behaviors are typically discouraged...

An ultra-short-acting benzodiazepine in thalamic nucleus reuniens undermines fear extinction via intermediation of hippocamposeptal circuits
Benzodiazepines, commonly used for anxiolytics, hinder conditioned fear extinction, and the underlying circuit mechanisms are unclear. Utilizing...

Heterogeneous selectivity and morphological evolution of marine clades during the Permian–Triassic mass extinction
Morphological disparity and taxonomic diversity are distinct measures of biodiversity, typically expected to evolve synergistically. However,...
-
Abundance does not predict extinction risk in the fossil record of marine plankton
A major premise of ecological neutral theory is that population size is inversely related to extinction risk. This idea is central to modern...

Decoupling speciation and extinction reveals both abiotic and biotic drivers shaped 250 million years of diversity in crocodile-line archosaurs
Whereas living representatives of Pseudosuchia, crocodylians, number fewer than 30 species, more than 700 pseudosuchian species are known from their...

Low extinction risk in the flower fly fauna of northeastern North America
IntroductionFlower flies (Diptera: Syrphidae; also known as hoverflies) are important pollinators of wild and cultivated plants. Other pollinators...

Mezcal Boom and Extinction Debts
In recent years, national and international demand for mezcal has exponentially increased, promoting deforestation and the overexploitation of agave...
-
The Current Status of Population Extinction and Biodiversity Crisis of Medicinal Plants
Loss of biodiversity or species extinction (the disappearance of existing species from the earth) and speciation (the origin of new species) are...

Synergistic effects of habitat fragmentation and hunting on the extinction risk of neotropical primates
Habitat fragmentation and overexploitation of natural resources are the most prevalent and severe threats to biodiversity in tropical forests....
-
No evidence for niche competition in the extinction of the South American saber-tooth species
The end of South American isolation during the Great American Biotic Interchange (GABI) promoted the contact between South and North American...
-
Effects of subpopulation extinction on effective size (Ne) of metapopulations
Population extinction is ubiquitous in all taxa. Such extirpations can reduce intraspecific diversity, but the extent to which genetic diversity of...

The loss of female sperm storage ability as a potential driver for increased extinction in Chondrichthyes
Female sperm storage (FSS) has been reported in Chondrichthyans species, and involves the prolonged maintenance of viable sperm after mating events,...

Can the extinction risk of Irish vascular plants be predicted using leaf traits?
Globally, 39% of vascular plant species are estimated to be threatened with extinction. Many factors are responsible for this figure; however, in...

Potential effects of brown howler monkey extinction on dispersal services in fragmented forests void of large dispersers
The dispersal of large-seeded species strongly depends on medium-sized and large frugivores, such as primates, which are highly susceptible to...
