Journal ArticleDOI
Recovery of gene diversity using long‐term cryopreserved spermatozoa and artificial insemination in the endangered black‐footed ferret
JoGayle Howard,C. Lynch,C. Lynch,Rachel M. Santymire,Rachel M. Santymire,Paul E. Marinari,David E. Wildt +6 more
TL;DR: It is reported the first successful integration of AI with frozen semen into a formal recovery program and the positive impact on genetic diversity for the critically endangered black‐footed ferret Mustela nigripes.
Journal ArticleDOI
Temporal shifts in activity of prey following large predator reintroductions
Craig J. Tambling,Liaan Minnie,Jordana M. Meyer,Jordana M. Meyer,Elizabeth W. Freeman,Rachel M. Santymire,John Adendorff,Graham I. H. Kerley +7 more
TL;DR: Investigating the activity patterns of species exposed to large predators in the Addo Elephant National Park suggests that prey species at risk of predation are more likely to be active diurnally when co-existing with nocturnally active predators, thereby reducing the activity overlap with these predators.
Journal ArticleDOI
Validation of a cortisol enzyme immunoassay and characterization of salivary cortisol circadian rhythm in chimpanzees (Pan troglodytes).
Matthew R. Heintz,Rachel M. Santymire,Rachel M. Santymire,Lisa A. Parr,Elizabeth V. Lonsdorf,Elizabeth V. Lonsdorf +5 more
TL;DR: Salivary cortisol concentrations peaked 45 min following the ACTH challenge, which is similar to humans, and saliva collection may be the most effective method of measuring stress reactivity and has the potential to complement behavioral, cognitive, physiological, and welfare studies.
Journal ArticleDOI
Genotypic and phenotypic consequences of reintroduction history in the black-footed ferret ( Mustela nigripes )
Samantha M. Wisely,Rachel M. Santymire,Rachel M. Santymire,Travis M. Livieri,Sara A. Mueting,JoGayle Howard +5 more
TL;DR: It appears that 5–10 years of isolation resulted in both genotypic divergence and phenotypic changes to populations, and translocation of 30–40 captive individuals per annum to reintroduction sites which have not become established quickly is recommended.
Journal ArticleDOI
Development of a field-friendly technique for fecal steroid extraction and storage using the African wild dog (Lycaon pictus).
TL;DR: Results demonstrated that, for C and T, HO was more comparable to LAB than HS and PT storage was more efficient than SPE (P<0.001), and the method to store and analyze samples for corticosterone (C) and testosterone (T) metabolites was developed.
