Organisms in the wild have to allocate limited resources towards competing functions such as reproduction, growth, and self-maintenance. These competing investments create significant changes in physiological activity, and we still know little about the relationship between physiological activity and reproductive investment in natura. We investigated trade-offs between physiological activity and reproductive investment in the parthenogenetic Colorado checkered whiptail, Aspidoscelis neotesselata, across three different sites at the US Army Fort Carson Military Installation near Colorado Springs, CO, through-out the reproductive season in 2018 and 2019. We measured clutch size and reproductive activity and quantified plasma corticosterone (CORT), reactive oxygen metabolites (ROMs), …

Smaller details of natural history often go undocumented to science if those details are not parts of larger studies, but small details can provide insights that lead to interesting questions about ecological relationships or environmental change. We have compiled recent important observations of distribution and reproduction of fishes and mammals. Included are new distributional records of mammals, and observations of reproduction in several mammals for which few data exist in Arkansas. A rare record of the Long-tailed weasel, a special of special concern in Arkansas, is documented from Newton Co. We also provide evidence that Seminole bats likely reproduce in …
Distribution And Reproduction By The Purple Gallinule (Porphyrio Martinica) In Arkansas, C. Renn Tumlison, Terry L. Tumlison, Tamzen T. Bryant
Distribution And Reproduction By The Purple Gallinule (Porphyrio Martinica) In Arkansas, C. Renn Tumlison, Terry L. Tumlison, Tamzen T. Bryant
Journal of the Arkansas Academy of Science
The Purple Gallinule (Porphyrio martinica) is a rare bird in Arkansas, and its populations likely have declined due to loss of marshy areas with emergent vegetation. By use of online sources for citizen science combined with a field study, we elucidate the current distribution of this bird in Arkansas, and document characteristics of reproduction and development. Purple Gallinules arrive in Arkansas as early as April and remain to late October. Nesting occurs from early May into July, and nests may represent second broods. Ontogenetic changes in hatchlings are described.
Assessment Of Indiana Bat Reproductive Condition, Recapture Trends, And Temperatures Of Artificial Roosts In Kentucky, Michaela L. Rogers

Recovery of bat species impacted by white-nose syndrome (WNS) will necessarily require population growth. I assessed reproductive capability of the endangered Indiana bat (Myotis sodalis) in Kentucky, where WNS was first detected in hibernacula in April 2011. Due to loss of fat reserves associated with WNS infection, coupled with the energetic expenditures associated with pregnancy, I hypothesized mass of reproductively-active females captured during the maternity season would decrease across my data collection period (2017-2019). Further, I predicted that reproductive rates in the study population would be lower than historic rates for Kentucky. Mist net surveys around artificial maternity roosts at …
