Sharp ecological boundaries often present animals with abrupt transitions in various resources, including the availability of food, potentially creating strong selective gradients. Yet little is known concerning how animals respond to abrupt shifts in resources, especially when gene flow may limit local adaptation. Here, we used DNA metabarcoding and untargeted metabolomics of fecal samples to begin characterizing the foraging ecology of two closely related rodents (Neotoma bryanti and N…

Differences in dietary composition and preference maintained despite gene flow across a woodrat hybrid zone
The results suggest that woodrats respond to fine‐scale environmental differences in plant availability that may require different metabolic strategies in order to balance nutrient acquisition while minimizing exposure to potentially toxic PSCs.
Multigenerational backcrossing and introgression between two woodrat species at an abrupt ecological transition
When organisms experience secondary contact after allopatric divergence, genomic regions can introgress differentially depending on their relationships with adaptation, reproductive isolation,


DNA metabarcoding illuminates dietary niche partitioning by African large herbivores
DNA metabarcoding was used to quantify diet breadth, composition, and overlap for seven abundant LMH species (six wild, one domestic) in semiarid African savanna, suggesting that LMH diversity may be more tightly linked to plant diversity than is currently recognized.
Convergent Evolution and Divergent Selection: Lizards at the White Sands Ecotone
This work investigates the role of gene flow in modulating phenotypic response to selection by quantifying color variation and genetic variation across the ecotone and finds species differences in degree of background matching and in genetic connectivity of populations across the Ecotone.
Plants and climate change: complexities and surprises.
It is argued that inconclusive, unexpected, or counter-intuitive results should be embraced in order to understand apparent disconnects between theory, prediction, and observation, and that the need for ecologists to conduct community-level experiments in systems that replicate multiple aspects of ACC is highlighted.
Review: Using physiologically based models to predict population responses to phytochemicals by wild vertebrate herbivores.
A physiologically based model that provides a mechanistic link between foraging decisions and demographic consequences is described and how estimated physiological parameters can be integrated with the geometric framework of nutrition and into integral projection models and agent-based models to predict fitness and population responses of vertebrate herbivores to ingested phytochemicals is illustrated.
Expression of biotransformation genes in woodrat (Neotoma) herbivores on novel and ancestral diets: identification of candidate genes responsible for dietary shifts
Large differences in expression of biotransformation genes when woodrats were fed juniper vs. creosote are found, consistent with the hypothesis that biotranformation enzymes limit diet switching and that woodrats in the Mojave have evolved a unique strategy for the biOTransformation ofcreosote toxins.
The Influence of Plant Secondary Metabolites on the Nutritional Ecology of Herbivorous Terrestrial Vertebrates
A detailed description of the biotransformation system with respect to plant secondary metabolites is given and some new tools that can be applied to long-standing questions of plant–vertebrate interactions are discussed.
Ecological Character Displacement and Speciation in Sticklebacks
Evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia is presented and the possibility that competition for food has played a critical role in the divergence between species is considered.
Ecological character displacement.
Some morphological differences between closely related species living in the same environment have been enhanced by natural selection resulting from competition between the species or the negative
The evolution of novel host use is unlikely to be constrained by trade‐offs or a lack of genetic variation
Results suggest that genetic trade‐offs are not the primary cause of dietary specialization in L. melissa butterflies, and most genetic variants that affected performance on one host had little to no effect on the other host.
A hot lunch for herbivores: physiological effects of elevated temperatures on mammalian feeding ecology
It is likely that increased ambient temperatures due to climate change may have greater and more‐specific impacts on herbivores than on other mammals, and that managing internal and external heat loads under these conditions could drive changes in feeding ecology.
