attribute NC_GLOBAL acquisition_description String We observed the behavior of individual crabs in situ. In each habitat, we\ncollected groups of five adult A. pisonii by hand and determined the sex and\ncarapace width (to the nearest 0.1mm) of each individual. The groups of crabs\nwere made up of the first five individuals that we encountered and could\ncapture and were drawn from all accessible habitat. We then painted the\ncarapace of each crab an identifying color with nail polish to aid in\nidentification and visibility. Following a short period of observation to\nensure normal behavior, we released the crabs onto a single tree within 10 m\nof the collection tree of all individuals (mangrove), onto separate S.\nalterniflora stalks within 10 m of the area of collection (saltmarsh), or onto\nthe same piling (dock) of the dock where all individuals were captured.\nRelease in the saltmarsh occurred during the rising tide when the crabs had no\naccess to the sediment.\n \nWe observed crabs in the mangrove and saltmarsh habitats from the time they\nlost access to the sediment until the receding tide once again allowed access\nto the sediment (~6h depending on site and day). In contrast, we observed\ncrabs on docks from three hours before slack high tide until three hours after\nslack high tide. The total time of observation, in minutes, was recorded. We\nwatched crabs from a distance using binoculars and monitored the individuals\ncontinuously throughout the observational period. Behavior was recorded every\nfive minutes and at every change in behavior within those five minute\nintervals as one of four categories: feeding, sitting, moving, or not-visible.\nFeeding was defined as the crab actively moving its claws from a food item or\nsubstrate to its mouth. Moving was defined as the crab actively moving along a\nsubstrate and not feeding. Other energy expending non-feeding activities, such\nas ritual aggression, were also classified under moving as they represent an\nexpenditure of energy. Sitting was defined as the crab not actively moving,\nfeeding, or participating in any activity. Invisible was defined as the crab\nnot being visible to the observer.\n \nWe separated the observations into ebb and flood tidal periods.\\u00a0\n \nTo avoid biasing the data with crabs that were not visible for long periods,\nwe removed data from individuals that were not visible for more than 66% of\nthe tidal period. To calculate the proportion of time each crab performed each\nactivity during each observational period we divided the minutes observed on\nthat activity by the total number of minutes of the observational period.\n \nLocations: Florida East Coast.  \n Round Island Park: 27o33'33\\\"N 80o19'53\\\"W  \n Pepper Park: 27o29'42'N 80o18'12\\\"W  \n Bear Point: 27o25'48\\\"N 80o17'10\\\"W  \n North Causeway Park: 27o28'28\\\"N 80o19'12\\\"W  \n Oslo Road: 27o35'14\\\"N 80o21'55\\\"W  \n Anastasia State Park: 29o52'40\\\"N 81o16'32\\\"W  \n Guana-Tolomato-Matanzas NERR: 30o0'49\\\"N 81o20'42\\\"W  \n Palm Valley/Nocatee Canoe Launch: 30o07'57\\\"N 81o23'08\\\"W  \n St. Augustine Yacht Club: 29o53'09\\\"N 81o17'08\\\"W

attribute NC_GLOBAL project String Variation in Metabolic Processes
attribute NC_GLOBAL projects_0_acronym String Variation in Metabolic Processes
attribute NC_GLOBAL projects_0_description String Description from NSF award abstract:\nA major goal of biological and ecological sciences is to understand natural systems well enough to predict how species and populations will respond to a rapidly changing world (i.e., climate change, habitat loss, etc.). A population under any conditions will grow, shrink, or disappear altogether depending on how efficiently individuals consume resources (food), utilize that food metabolically, and eventually reproduce. However, making accurate predictions based on these metabolic processes is complicated by the realities that each species has different resource requirements and that no two individuals within a species are exactly alike. Rather, individuals vary and this variation, both within and across species, is central to many ecological and evolutionary processes. Developing the ability to predict responses of biological systems to a changing world therefore requires a mechanistic understanding of variation. The goal of this project is to improve this mechanistic understanding by examining variation within a metabolic context across a range of species that have a spectrum of commonly-seen resource requirements. Further, the work capitalizes on a unique biological characteristic of this group of species that allows control and manipulation of individual reproduction, facilitating experimental study of the mechanistic links between variation in individual consumption, metabolism, and reproduction. The foundation this research is a combination of field measurements and laboratory experiments using both well-established and newly-developed techniques to quantify these links. The result will be a quantitative framework to predict how individuals will respond reproductively to changes in resource use. Because of the close link between individual reproduction and population dynamics, this research will contribute substantially to predictions in population dynamics under realistic conditions where individuals use more than a single resource, and improve the prediction of responses to current and future ecological changes.\nThe following publications and data resulted from this project:\nBelgrad, B. and B.
