Metabolic Demands of a Tropical Marine Carnivore, the Hawaiian Monk Seal (Monachus schauinslandi): Implications for Fisheries Competition

Hepatitis associated with a Sarcocystis canis-like protozoan in a Hawaiian monk seal (Monachus schauinslandi).

A Hawaiian monk seal (Monachus schauinslandi) died in captivity at the National Marine Fisheries Service, Kewalo Basin Facility in Honolulu, Hawaii. The animal was icteric, and the liver was friable. Microscopic lesions were detected in the colon and liver. Colonic lesions included multifocal, necrohemorrhagic colitis associated with gram-negative bacilli. The liver lesions included random hepa...

Non-lethal efforts to deter shark predation of Hawaiian monk seal pups

1. More than a decade of shark predation on nursing and newly weaned pups of the endangered Hawaiian monk seal (Monachus schauinslandi) has significantly contributed to a steep decline of the French Frigate Shoals (FFS)

Toxoplasmosis in a Hawaiian monk seal (Monachus schauinslandi).

Toxoplasma gondii infection in marine mammals is intriguing and indicative of contamination of the ocean environment with oocysts. T. gondii was identified in a Hawaiian monk seal (Monachus schauinslandi) that had visceral and cerebral lesions. Tachyzoites were found in the lymph nodes, spleen, diaphragm, heart, adrenal glands, and brain. A few tissue cysts were found in sections of the cerebru...

Relative influence of climate variability and direct anthropogenic impact on a sub-tropical Pacific top predator, the Hawaiian monk seal

Abundance trends of Hawaiian monk seals Monachus schauinslandi at 6 subpopulations throughout the Northwestern Hawaiian Islands (NWHI) have fluctuated considerably during the past 5 decades. Direct human impacts have been widely accepted as the primary cause of previous monk seal population declines and, consequently, much conservation effort has focused on minimizing these threats. Yet climate...
