trends in stranding and by-catch rates of gray and harbor seals along the northeastern coast of the united states: evidence of divergence in the abundance of two sympatric phocid species?harbor seals and gray seals are sympatric phocid pinnipeds found in coastal waters of the temperate and sub-arctic north atlantic. in the northwest atlantic, both species were depleted through a combination of subsistence hunts and government supported bounties, and are now re-occupying substantial portions of their original ranges. while both species appear to have recovered during the past 2 decades, our understanding of their population dynamics in us waters is incomplete. here we describe tr ...201526200461
the identification of a new giardia duodenalis assemblage in marine vertebrates and a preliminary analysis of g. duodenalis population biology in marine systems.giardia duodenalis is an intestinal parasite of many vertebrates. the presence of g. duodenalis in the marine environment due to anthropogenic and wildlife activity is well documented, including the contributions from untreated sewage and storm water, agricultural run-off and droppings from terrestrial animals. recently, studies have detected this protistan parasite in the faeces of marine vertebrates such as whales, dolphins, seals and shore birds. to explore the population biology of g. duoden ...201020361967
mortality trends of stranded marine mammals on cape cod and southeastern massachusetts, usa, 2000 to understand the cause of death of 405 marine mammals stranded on cape cod and southeastern massachusetts between 2000 and 2006, a system for coding final diagnosis was developed and categorized as (1) disease, (2) human interaction, (3) mass-stranded with no significant findings, (4) single-stranded with no significant findings, (5) rock and/or sand ingestion, (6) predatory attack, (7) failure to thrive or dependent calf or pup, or (8) other. the cause of death for 91 animals could not be dete ...201020225675
