Physiological parameters derived from dissection of A. pisonii from three habitats Dataset Description: <p>This dataset includes multiple physiological parameters derived from dissection of&nbsp;mangrove tree crabs, A. pisonii, from three habitats: mangrove, saltmarsh and mangrove.</p> Methods and Sampling: <p>On each of 9 randomly selected days in each habitat, 15 individual adult A. pisonii were collected by hand and immediately placed on dry ice. In the mangrove and saltmarsh, we collected these crabs in three groups of five at three distinct tidal periods: just after losing access to the sediment on the flood tide, at slack high tide, and just before regaining access to the sediment on the ebb tide. Crabs were kept frozen until dissection. Prior to dissection, we determined the sex and carapace width of each crab. Upon dissection we ascertained gut-width as the width of the cardiac stomach.</p>
<p>We ascertained the gut fullness of each crab to obtain a snap-shot of the quantity of food consumed during each tidal period by removing the gut contents and drying them at 60-70oC to constant weight. We standardized gut fullness by dividing the mass of the gut contents by the volume of the gut ( ) where a is a correction factor of 0.92.</p>
<p>We also separated the hepatopancreas, reproductive tissue (gonads and eggs), feces still in the intestines, the gut, and the somatic tissue of each crab and dried them to a constant weight at 60-70oC.</p>
<p>The dry mass of each parameter was determined by subtracting the mass of the weigh boat used for that parameter from the dry mass of that parameter on the weigh-boat.</p>
<p>Hepatosomatic index was calculated as the ratio of the dry masses of the hepatopancreas and the somatic tissue.<br />
Gonadosomatic index was calculated as the ratio of the dry masses of the reproductive tissues and the somatic tissue.<br />
Gut volume was calculated using the equation ( ) where a is a correction factor of 0.92.</p>

Linking Variation in Metabolic Processes as a Key to Prediction
<p><em>Description from NSF award abstract:</em><br />
A 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.</p>

dataset
<p>On each of 9 randomly selected days in each habitat, 15 individual adult A. pisonii were collected by hand and immediately placed on dry ice. In the mangrove and saltmarsh, we collected these crabs in three groups of five at three distinct tidal periods: just after losing access to the sediment on the flood tide, at slack high tide, and just before regaining access to the sediment on the ebb tide. Crabs were kept frozen until dissection. Prior to dissection, we determined the sex and carapace width of each crab. Upon dissection we ascertained gut-width as the width of the cardiac stomach.</p>
<p>We ascertained the gut fullness of each crab to obtain a snap-shot of the quantity of food consumed during each tidal period by removing the gut contents and drying them at 60-70oC to constant weight. We standardized gut fullness by dividing the mass of the gut contents by the volume of the gut ( ) where a is a correction factor of 0.92.</p>
<p>We also separated the hepatopancreas, reproductive tissue (gonads and eggs), feces still in the intestines, the gut, and the somatic tissue of each crab and dried them to a constant weight at 60-70oC.</p>
<p>The dry mass of each parameter was determined by subtracting the mass of the weigh boat used for that parameter from the dry mass of that parameter on the weigh-boat.</p>
<p>Hepatosomatic index was calculated as the ratio of the dry masses of the hepatopancreas and the somatic tissue.<br />
Gonadosomatic index was calculated as the ratio of the dry masses of the reproductive tissues and the somatic tissue.<br />
Gut volume was calculated using the equation ( ) where a is a correction factor of 0.92.</p>
