Nassau grouper Epinephelus striatus are a large bodied, top level predator that is ecologically important throughout
the Caribbean. Although typically solitary, Nassau grouper form large annual spawning aggregations at predictable times in specific
locations. In 2003, The Cayman Islands Marine Conservation Board established protection for a newly rediscovered Nassau
Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms
are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce
reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual
In many animal species, males direct more intense courtship towards females they have not previously encountered,
than towards females with which they have previously mated. To test the factors responsible for this "Coolidge Effect", we need
studies on a wide range of taxa – including those with mating systems in...
The data is a JSON format file containing the position, velocity, and fish identifier data for 300 golden shiners in a shallow (depth of 4.5 to 5 cm) rectangular water tank (2.1 by 1.2 meters). There are 5000 individual frames (samples of position and velocity) corresponding to video taken at...
The focus of postcolonial studies has shifted in the last decade or so from
a struggle over history, the narratives of winners and losers—as recorded
by the winners and resisted by the losers—to a struggle over geography.
Power inequities formerly embodied in Manichean conceptualizations
(Colonizer/Colonized, Oppressor/Oppressed, Occidental/Oriental,
Self/Other, First World/Third...
Transferrin of Columbian black-tailed deer (Odocoileus
hemionus columbianus) displayed two types of polymorphism. One
type involved differences in sialic acid content. The nature of the
other polymorphism is not known. A hypothesis for three codominant
alleles at a common locus was proposed and tested by using the
Hardy-Weinberg Principle. The...
The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied
raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use
recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate
