Hypotheses are presented to account for the endemic Novumbra and Oregonichthys and 2 areas along the Oregon coast with depauperate faunas.
The prevalence of small carabid beetles at high altitude or in sites stressed by strong disturbances is probably due to depauperate food availability in these areas [18, 19, 56, 57].
2011, GSMFC 2012), landings data, and initial surveys of the system, oyster reefs are depauperate in the PBS relative to other GOM and eastern U.S.
We suggest this discordance could be a sensitive indicator of a population just beginning to feel the effects of isolation, even though it is not yet significantly inbred or otherwise genetically depauperate. This research might therefore serve as an example of how to detect the genetic effects of range contractions for potentially threatened populations of other mammal species before they become critically endangered.
The clearest signal of parasite biogeographic structure that loosely correlates with host phylogeography is the apparent division between the distinct and relatively depauperate southwestern parasite fauna and the more complex fauna of the north and east.
For instance, the role of larvae in the otherwise depauperate food webs of the anchialine ecosystem remains unexplored.
This means that the gene pools for these populations of insects could be genetically depauperate. In a study conducted by [16], populations of B.
The notion of long-ago rigid parts "may help explain why these animals, now represented by forms with flimsy and rapidly degradable bodies, have a fossil record that is comparatively rich in the Ediacaran-Cambrian [periods] but quite depauperate after that."
(32) Furthermore, technological advances in genetic manipulation achieved through de-extinction efforts--such as the use of cryopreserved gametes (33) (or even ancient DNA from preserved materials) to obtain and introduce new beneficial alleles into an existing population--might be useful if employed to increase the genetic diversity of existing endangered species populations or to engage in "genetic rescue" for endangered species that are genetically depauperate. (34) Genetic-engineering technologies might also be used to insert new genes into the genome of a vulnerable species to enhance its fitness in the face of threats such as introduced pathogens or parasites.
Nevertheless, Smith's (2009) assessment of Shelly Beach as relatively depauperate remains broadly valid.
