Thus, many questions regarding oyster metapopulation dynamics remain, particularly with respect to relative retention, connectivity, and repopulation of depauperate habitats.
Genetic factors including low mutation rates, not accumulated or fixed variability in the species' gene pool, and/or having originated from a genetically depauperate ancestor with a restricted geographical distribution, may have also influenced.
Over a century ago, when Woodworth (1900) described the first vertebrate tracks from the Narragansett Basin, he noted the depauperate state of knowledge of Carboniferous ichnofaunas from New England in comparison to those described from elsewhere, such as the Maritime Provinces of Canada and farther south in the Appalachians.
In summary, lungs of Texas alligators are depauperate in species richness (similar to alligator populations from Louisiana and Florida) whereas the stomach and intestines are parasitized by a diversity of endoparasites.
2005); either Indiana is depauperate in relation to Illinois, Ohio, Wisconsin, and Michigan or there has been inadequate study of spider diversity within the state (383 spider species known from Indiana in comparison to 646, 571, 479, and 563 from Illinois, Ohio, Wisconsin, and Michigan, respectively).
Also, the diversity indices indicate that all populations are exhibiting high levels of diversity and that the AP population is not currently showing signs of being genetically depauperate.
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.
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.
