Influence of possible stressors on the respiration of three female Pacific Walruses (Odobenus rosmarus divergens), housed in managed care
In the present study we evaluated how feeding, enrichment, and presence of public affected breathing frequency (fR) in three females of Pacific walruses (Odobenus rosmarus divergens) housed in managed care at the Avanqua Oceanogràfic Ágora in Valencia, Spain. The fR was measured as the walruses were...
