Fecal Methylmercury Correlates With Gut Microbiota Taxa in Pacific Walruses ().

Objectives: Methylmercury metabolism was investigated in Pacific walruses () from St. Lawrence Island, Alaska, United States.

Methods: Total mercury and methylmercury concentrations were measured in fecal samples and paired colon samples ( = 16 walruses).

BRIDGING GAPS BETWEEN ZOO AND WILDLIFE MEDICINE: ESTABLISHING REFERENCE INTERVALS FOR FREE-RANGING AFRICAN LIONS (PANTHERA LEO).

The International Species Information System has set forth an extensive database of reference intervals for zoologic species, allowing veterinarians and game park officials to distinguish normal health parameters from underlying disease processes in captive wildlife. However, several recent studies comparing reference values from captive and free-ranging animals have found significant variation between populations, necessitating the development of separate reference intervals in free-ranging wildlife to aid in the interpretation of health data. Thus, this study characterizes reference intervals for six biochemical analytes, eleven hematologic or immune parameters, and three hormones using samples from 219 free-ranging African lions ( Panthera leo ) captured in Kruger National Park, South Africa.
