Title:	Trophic interactions of fiddler crabs (Uca spp.) with black mangrove (Avicennia germinans) detrital matter as a result of mangrove encroachment; 2018 and 2019
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Woody plant encroachment is reshaping communities in both terrestrial and coastal environments, but little is known about its effects on basal consumers. We used interactions between fiddler crabs (Uca spp.) and the encroaching mangrove Avicennia germinans in Gulf of Mexico salt marshes to explore trophic interactions between basal consumers and encroaching shrubs. Fiddler crabs were collected from wetlands in Galveston, Texas in summer 2018 and 2019 and used in a series of food preference and food quality trials. Through these trials we collected data on the relative attractiveness and quality of black mangroves and smooth cordgrass (Spartina alterniflora) as food sources for fiddler crabs.

Methods and protocols used in the collection of this data package

Description:

Fiddler crabs for all trials were collected from various wetlands on Galveston Island, Texas. Crabs for food preference trials were starved for 48 hours prior to trial start, while food quality trials began immediately with freshly caught crabs. Diets for each experiment were made by collecting plants of the necessary species in local wetlands, then rinsing, drying at 60degreeC, and grinding the leaves in the labs. Ground plant powder was mixed with cleaned sand to form a simulated detrital diet. Five food preference trials were performed with each of the species of fiddler crabs present in the area, for a total of 15 trials. Food preference trials took place in a 2-meter diameter feeding arena with 9 food dishes (3 each of Spartina alterniflora diet, Avicennia germinans diet, and control diet of cleaned store-bought sand). Crabs were allowed to feed freely for 24 hours, then the number of pseudofeces on the surface of each dish was counted and averaged by diet. Food quality was evaluated by raising 30 crabs (5 males and 5 females of each of the three species) on Avicennia and Spartina diets for 60 days. At the end of 60 days, crab growth, hepatopancreas lipid content, hepatosomatic index, and hepatopancreas C:N ratio were all evaluated. Lipid content was measured using a protocol adapted from Parrish (1999) (Chapter 1 in: Lipids in Freshwater Ecosystems, ISBN 9781461268130). Carbon and nitrogen content of dried and ground hepatopancreas tissue was measured on a Costech ECS 4010 CHNSO Analyzer.
