Data from: The effects of lipid extraction on δ13C and δ15N values and use of lipid-correction models across tissues, taxa, and trophic groups

Carl Cloyed, Kayla DaCosta, Matthew Hodanbosi & Ruth Carmichael
Lipid-rich animal tissues have low δ13C values, which can lead to inaccurate ecological inferences. Chemical lipid extraction (LE) or correction models account for this depletion, but the need for LE or correction is tissue- and species-specific. Also, LE can alter δ15N values, increasing labor and costs because bulk samples must be analyzed for δ15N values separately. We studied the effects of LE on δ13C and δ15N values in liver, muscle, and skin of common bottlenose...

Intraspecific dietary variation in niche partitioning within a community of ecologically similar snakes

Micah Perkins, Carl Cloyed & Perri Eason
Niche partitioning is an important mechanism for allowing ecologically similar species to coexist, contributing to biodiversity and the functioning of ecological communities. Species partition niches by taking advantage of environmental heterogeneity. However, niche partitioning and species coexistence investigations often do not include intraspecific variation or individual differences like sex and body size even though these factors can have important ecological consequences. Such intrapopulation factors can reduce the number of individuals among species that overlap in...
