ESTABLISHING HEMATOLOGY AND SERUM CHEMISTRY REFERENCE INTERVALS FOR WILD HAWAIIAN MONK SEALS ( NEOMONACHUS SCHAUINSLANDI).

Hematology and serum chemistry reference intervals have been previously established for the endangered Hawaiian monk seal ( Neomonachus schauinslandi) as an imperative measure for health assessments. Monitoring the health of the wild population depends upon reference intervals that are context specific; hence we developed reference intervals from fresh samples, as opposed to frozen, from wild monk seals. This study builds on the number of parameters from previous efforts by using samples collected between 2004 and 2015 from wild monk seals.

Protozoal-related mortalities in endangered Hawaiian monk seals Neomonachus schauinslandi.

Protozoal infections have been widely documented in marine mammals and may cause morbidity and mortality at levels that result in population level effects. The presence and potential impact on the recovery of endangered Hawaiian monk seals Neomonachus schauinslandi by protozoal pathogens was first identified in the carcass of a stranded adult male with disseminated toxoplasmosis and a captive monk seal with hepatitis. We report 7 additional cases and 2 suspect cases of protozoal-related mortality in Hawaiian monk seals between 2001 and 2015, including the first record of vertical transmission in this species.
