Tb194: Hemisgrapsus Sanguineus (Asian Shore Crab) As Predator Of Juvenile Homarus Americanus (American Lobster), Anna Demeo, John G. Riley

Technical Bulletins

Hemigrapsus sanguineus, commonly known as the Asian shore crab, was first discovered on the east coast of the United States in New Jersey in 1988. The spread of this invasive crab has been rapid, and it is now abundant along a large portion of the mid-Atlantic and southern New England coast. Further, an invasion of H. sanguineus into New Hampshire and southern Maine is in its preliminary stages. The introduction of this crab to North America could potentially affect a variety of native species. Numerous studies have examined the predation of H. sanguineus on blue mussels, snails, and other bivalves ...

In the United States, many of the laws governing environmental conservation and management stipulate that the best available science be used as the basis for policy and decision making. The Endangered Species Act, for example, requires that decisions on listing a species as threatened or endangered be made on the basis of the "best scientific and commercial data available." Similarly, National Standard 2 of the Magnuson-Stevens Fishery Conservation and Management Act states that conservation and management measures shall be based on "the best scientific information available." Further, the U.S. Environmental Protection Agency has emphasized the role of best available ...


Phenotypic Divergence Of Indigenous And Translocated Arctic Charr (Salvelinus Alpinus) Populations In Maine, Wendy K. Michaud Jan 2006

Phenotypic Divergence Of Indigenous And Translocated Arctic Charr (Salvelinus Alpinus) Populations In Maine, Wendy K. Michaud

Electronic Theses and Dissertations

Selection on traits related to trophic ecology is recognized as an important contributing factor in adaptive divergence and speciation. For several freshwater fish species, including Arctic charr (Salvelinus alpinus), such selection is commonly reflected in relationships between diet, habitat use and phenotypic divergence. Trophic specializations that emerge have been extensively studied among sympatric forms, but much less is known of the extent of this type of divergence in allopatry. Trait differences among these forms are also thought to reflect thousands of years of evolution, making it difficult to examine root causes of such divergence in natural populations. Here, I address ...
