bioturbation by mammals and fire interact to alter ecosystem-level nutrient dynamics in longleaf pine forests. | activities of ecosystem engineers can interact with other disturbances to modulate rates of key processes such as productivity and nutrient cycling. bioturbation, movement of soil by organisms, is a widespread form of ecosystem engineering in terrestrial ecosystems. we propose that bioturbation by southeastern pocket gophers (geomys pinetis), an abundant but declining ecosystem engineer in longleaf pine (pinus palustris mill.) forests, accelerates nutrient dynamics of the forest floor by burying ... | 2018 | 30133444 |

mitochondrial dna clones and matriarchal phylogeny within and among geographic populations of the pocket gopher, geomys pinetis. | restriction endonuclease assay of mitochondria dna (mtdna) and standard starch-gel electrophoresis of proteins encoded by nuclear genes have been used to analyze phylogenetic relatedness among a large number of pocket gophers (geomys pinetis) collected throughout the range of the species. the restriction analysis clearly distinguishes two populations within the species, an eastern and a western form, which differ by at least 3% in mtdna sequence. qualitative comparisons of the restriction phenot ... | 1979 | 293756 |
reevaluation of a classic phylogeographic barrier: new techniques reveal the influence of microgeographic climate variation on population divergence. | we evaluated the mtdna divergence and relationships within geomys pinetis to assess the status of formerly recognized geomys taxa. additionally, we integrated new hypothesis-based tests in ecological niche models (enm) to provide greater insight into causes for divergence and potential barriers to gene flow in southeastern united states (alabama, florida, and georgia). our dna sequence dataset confirmed and strongly supported two distinct lineages within g. pinetis occurring east and west of the ... | 2013 | 23789071 |
karyotype of geomys pinetis (mammalia: geomyidae), with a discussion of the chromosomal relationships within the genus. | 4 of the 5 subspecies of geomys pinetis were karyotyped. all specimens examined had a diploid number of 42 and a fundamental number of 80. this karyotype was compared with the described karyotypes of other species of geomys and was considered to be derived from an ancestoral form having a karyotype of about 70 acrocentric elements. | 1960 | 1204724 |
