Lab experiment linking dietary consumption and reproduction Dataset Description: <p>This data set is from an experiment that varied the total amount of food present and the proportion of that food that was animal or algal tissue in the diet. We maintained crabs on the same diet for 8 weeks, after which we quantified their reproductive effort and physiological condition.</p>
<p><strong>Related Reference:</strong>&nbsp;Griffen BD, Riley ME (2015) Potential impacts of invasive crabs on one life history strategy of native rock crabs in the Gulf of Maine. <em>Biological Invasions</em> 17:2533-2544.</p> Methods and Sampling: <p>Crabs were maintained in a recirculating aquarium in conditions that reflected those of their collection site in the fall (temperature: 13 degrees C and&nbsp;salinity: 33–34 ppt). Each crab was maintained in an individual experimental chamber that was submerged in the recirculating aquarium. Experimental chambers were individually plumbed so that each had a constant flow of water. Crabs were initially weighed and these initial weights were used to determine the amount of food that they would receive. Crabs were randomly assigned to food treatments which crossed four levels of food amount (1, 2, 4, 8 % of body weight per day) and five levels of proportion of that food that was animal tissue or algae (all animal, 0.25 animal and 0.75 plant, 0.5 of each, 0.75 animal and 0.25 plant, all animal). The red alga Chondrus crispus was the plant material offered to crabs in this experiment and the animal tissue was Tilapia filets.</p>
<p>Crabs were fed twice per week (Monday and Thursday), and uneaten food was removed after 48 h, dried at 70 degrees C for 48 h, and weighed. At the conclusion of the experiment we dissected each crab and removed the ovaries and the hepatopancreas.&nbsp; We calculated the gonadosomatic index (GSI), or the proportion of body weight allocated to the ovaries, and the hepatosomatic index (HSI), or the proportion of body weight allocated to the hepatopancreas.</p>

Linking Variation in Metabolic Processes as a Key to Prediction

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>

<p>Crabs were maintained in a recirculating aquarium in conditions that reflected those of their collection site in the fall (temperature: 13 degrees C and&nbsp;salinity: 33–34 ppt). Each crab was maintained in an individual experimental chamber that was submerged in the recirculating aquarium. Experimental chambers were individually plumbed so that each had a constant flow of water. Crabs were initially weighed and these initial weights were used to determine the amount of food that they would receive. Crabs were randomly assigned to food treatments which crossed four levels of food amount (1, 2, 4, 8 % of body weight per day) and five levels of proportion of that food that was animal tissue or algae (all animal, 0.25 animal and 0.75 plant, 0.5 of each, 0.75 animal and 0.25 plant, all animal). The red alga Chondrus crispus was the plant material offered to crabs in this experiment and the animal tissue was Tilapia filets.</p>
<p>Crabs were fed twice per week (Monday and Thursday), and uneaten food was removed after 48 h, dried at 70 degrees C for 48 h, and weighed. At the conclusion of the experiment we dissected each crab and removed the ovaries and the hepatopancreas.&nbsp; We calculated the gonadosomatic index (GSI), or the proportion of body weight allocated to the ovaries, and the hepatosomatic index (HSI), or the proportion of body weight allocated to the hepatopancreas.</p>
