| phylogeographic concordance in the southeastern united states: the flatwoods salamander, ambystoma cingulatum, as a test case. | well-supported, congruent phylogeographic and biogeographic patterns permit the development of a priori phylogeographic and distributional predictions. in the southeastern coastal plain of the united states, the common discovery of east-west disjunctions (phylogeographic breaks and species' distributional boundaries) suggests that similar disjunctions should occur in codistributed taxa. despite the near ubiquity of these disjunctions, the most recent morphological analyses of the flatwoods salam ... | 2007 | 17217354 |
| hindcasting historical breeding conditions for an endangered salamander in ephemeral wetlands of the southeastern usa: implications of climate change. | the hydroperiod of ephemeral wetlands is often the most important characteristic determining amphibian breeding success, especially for species with long development times. in mesic and wet pine flatwoods of the southeastern united states, ephemeral wetlands were a common landscape feature. reticulated flatwoods salamanders (ambystoma bishopi), a federally endangered species, depend exclusively on ephemeral wetlands and require at least 11 weeks to successfully metamorphose into terrestrial adul ... | 2016 | 26910245 |
| reconciling larval and adult sampling methods to model growth across life-stages. | individual growth rates are intrinsically related to survival and lifetime reproductive success and hence, are key determinants of population growth. efforts to quantify age-size relationships are hampered by difficulties in aging individuals in wild populations. in addition, species with complex life-histories often show distinct shifts in growth that cannot be readily accommodated by traditional modelling techniques. amphibians are often characterized by rapid larval growth, cessation of growt ... | 2020 | 32822355 |
| depauperate major histocompatibility complex variation in the endangered reticulated flatwoods salamander (ambystoma bishopi). | reticulated flatwoods salamander (ambystoma bishopi) populations began decreasing dramatically in the 1900s. contemporary populations are small, isolated, and may be susceptible to inbreeding and reduced adaptive potential because of low genetic variation. genetic variation at immune genes is especially important as it influences disease susceptibility and adaptation to emerging infectious pathogens, a central conservation concern for declining amphibians. we collected samples from across the ex ... | 2020 | 32300829 |
