Some of the traits of individual fish species make them more vulnerable to environmental perturbations, and these traits increase the probability of their local extinctions
(Angermeier, 1995; Bergerot, Hugueny, & Belliard, 2015).
The mainland population is large enough to resist local extinction
effectively, and supplies smaller, more extinction-prone island populations with colonists.
Most likely, population decline triggered by anthropogenic activities over the past half century may be the probable reason for its local extinction
In this paper we describe the Mangarevan example of the early transport and then local extinction
of the chicken, pig and dog by the time of first contact with Europeans in the early 19th century as deduced from an analysis of the faunal material.
As such, regular fires cause local extinction
of this frog.
The answer depends on a number of factors such as the risk of extinction of local populations, the rate of migration among populations, and the correlation among local extinction
events (Burgman et al.
With a Bonferroni correction for multiple tests, trends in probabilities of local extinction
with decreasing fragment area were considered statistically significant at P [is less than] 0.
Pannell (1997b) demonstrated the effects of local extinction
and recolonization on the maintenance of cosexuality versus unisexuality in a model that explicitly recognized the advantage enjoyed by hermaphrodites over unisexuals in colonizing unoccupied sites.
He also stated that hunting could lead to the local extinction
of lions in heavily hunted areas.
Pilanesberg did raise some questions, since many of the larger mammals in the park had been hunted to local extinction
decades before and were only recently "stocked" from other parts of Africa.
It focuses on species that inhabit fragmented habitats, in order to assess the risk of local extinction
and discern what may help the species to survive in a landscape subject to growing human influence.
Any further losses of yellow-eyed penguins will bring forward the date of their local extinction
," he said.
