Daily energy expenditure in free-ranging Gopher Tortoises (Gopherus polyphemus) Daily energy expenditure in free-ranging Gopher Tortoises (Gopherus polyphemus)
Studies of ecological energetics in chelonians are rare. Here, we report the first measurements of daily energy expenditure (DEE) and water influx rates (WIRs) in free-ranging adult Gopher Tortoises (Gopherus polyphemus). We used the doubly labeled water (DLW) method to measure DEE in six adult tortoises during the non-breeding season in south-central Mississippi, USA. Tortoise DEE...

Assessment of gamete quality for the eastern oyster (Crassostrea virginica) by use of fluorescent dyes Assessment of gamete quality for the eastern oyster (Crassostrea virginica) by use of fluorescent dyes
Evaluation of sperm motility is the single most widely used parameter to determine semen quality in mammals and aquatic species. While a good indicator for fresh sperm viability, post-thaw motility is not always effective at predicting fertilizing ability. Techniques using fluorescent dyes can assess functionality of mammalian sperm, but have not been widely applied in aquatic organisms...

Towards sustainable management of Louisiana's coastal wetland forests: Problems, constraints, and a new beginning Towards sustainable management of Louisiana's coastal wetland forests: Problems, constraints, and a new beginning
Over 345,000 ha of forested swamps occur throughout the Mississippi River Deltaic Plain. Natural and anthropogenic changes in hydrology and geomorphology at local and landscape levels have reduced the productivity in many of these coastal wetland forests areas and have caused the complete loss of forest cover in some places. A summary and interpretation of the available science...

Coastal forests of the Gulf of Mexico: A description and some thoughts on their conservation Coastal forests of the Gulf of Mexico: A description and some thoughts on their conservation
Millions of Nearctic-Neotropical landbirds move through the coastal forests of the Gulf of Mexico each spring and autumn as they migrate across and around the gulf. Migration routes in the gulf region are not static—they shift year to year and season to season according to prevailing wind patterns. Given the dynamic nature of migration routes, coastal forests around the Gulf of Mexico...

Individual-based modeling of ecological and evolutionary processes Individual-based modeling of ecological and evolutionary processes
Individual-based models (IBMs) allow the explicit inclusion of individual variation in greater detail than do classical differential-equation and difference-equation models. Inclusion of such variation is important for continued progress in ecological and evolutionary theory. We provide a conceptual basis for IBMs by describing five major types of individual variation in IBMs: spatial...

Pattern-oriented modeling of agent-based complex systems: Lessons from ecology Pattern-oriented modeling of agent-based complex systems: Lessons from ecology
Agent-based complex systems are dynamic networks of many interacting agents; examples include ecosystems, financial markets, and cities. The search for general principles underlying the internal organization of such systems often uses bottom-up simulation models such as cellular automata and agent-based models. No general framework for designing, testing, and analyzing bottom-up models...
