Erasing the extinct: the hunt for Caribbean monk seals and museum collection practices [PDF]
The Caribbean monk seal (Monachus tropicalis), the only seal species native to Central America, was declared extinct in 2008, with the last confirmed sighting in 1952. This species historically had a broad range throughout the gulf of Mexico.

Extinction and morphospace occupation: A critical review
Processes of extinction, especially selectivity, can be studied using the distribution of species in morphospace. Random extinction reduces the number of species but has little effect on the range of morphologies or ecological roles in a fauna or flora ...

Are extinction opinions extinct? [PDF]
Extinction models vary in the information they require, the simplest considering the rate of certain sightings only. More complicated methods include uncertain sightings and allow for variation in the reliability of uncertain sightings. Generally extinction models require expert opinion, either as a prior belief that a species is extinct, or to ...

Pinpointing Drivers of Extirpation in Sea Snakes: A Synthesis of Evidence From Ashmore Reef
Over the past decade, vertebrate populations globally have experienced significant declines in distribution and abundance. Understanding the reasons behind these population declines is the first step in implementing appropriate management responses to ...

Ex situ management of wildlife provides a possibility for species maintenance, research development and environmental education. But as captive facilities are usually much smaller than the area occupied by a species in the natural habitat, cleaning ...

Hybridization and extinction [PDF]
AbstractHybridization may drive rare taxa to extinction through genetic swamping, where the rare form is replaced by hybrids, or by demographic swamping, where population growth rates are reduced due to the wasteful production of maladaptive hybrids. Conversely, hybridization may rescue the viability of small, inbred populations.

The colonization of Mauritius exemplifies the role played by humans in altering the ecosystems of remote oceanic islands. This paper focuses on how we study those islands first colonized under the global mantle of colonialism.

Thirty years ago, biologists began to predict how climate change would alter species’ ranges, extinctions, and their roles in ecosystems (1). Since then, evidence has begun to confirm these nascent predictions. The current global temperature rise of ∼1 °C has shifted species up mountains and latitudes (2), altered the timing of key life events such as ...
