Analysis of Stable Isotopes of Hydrogen to Determine Migrational Source of Silver-Haired Bats (Lasionycteris noctivagans) in Alabama
Signatures of deuterium obtained from claws of 21 silver-haired bats (Lasionycteris noctivagans) were used to estimate the nearest probable pre-migratory location of these bats. For 5 consecutive weekends beginning 28 ...
Sexual Dimorphism, the Big-Mother Hypothesis, and Analyses of Hormones, Minerals, and Stable Isotopes to Determine Reproductive Events in Bowhead Whales (Balaena mysticetus)
Baleen from bowhead whales (Balaena mysticetus) provided an opportunity to study reproduction and sexual dimorphism via analyses of hormones, minerals, and stable-isotopes. Concentration of progesterone in baleen was ...
