Data from: Ecological segregation in a small mammal hybrid zone: habitat-specific mating opportunities and selection against hybrids restrict gene flow on a fine spatial scale

Quinn Rodney Shurtliff, Peter J. Murphy & Marjorie D. Matocq
The degree to which closely related species interbreed is determined by a complex interaction of ecological, behavioral, and genetic factors. We examine the degree of interbreeding between two woodrat species, Neotoma bryanti and N. lepida, at a sharp ecological transition. We identify the ecological association of each genotypic class, assess the opportunity for mating between these groups, and test whether they have similar patterns of year-to-year persistence on our study site. We find that 13%...

Data from: A method for estimating population sex ratio for sage-grouse using noninvasive genetic samples

Jeremy A. Baumgardt, Caren S. Goldberg, Kerry P. Reese, Jack W. Connelly, David D. Musil, Edward O. Garton & Lisette P. Waits
Population sex ratio is an important metric for wildlife management and conservation, but estimates can be difficult to obtain, particularly for sexually monomorphic species or for species that differ in detection probability between the sexes. Noninvasive genetic sampling (NGS) using polymerase chain reaction (PCR) has become a common method for identifying sex from sources such as hair, feathers, or feces, and is a potential source for estimating sex ratio. If, however, PCR success is sex-biased,...

Data from: Chromosomal rearrangements and the genetics of reproductive barriers in Mimulus (monkeyflowers)

Lila Fishman, Angela Stathos, Paul M. Beardsley, Charles F. Williams & Jeffrey P. Hill
Chromosomal rearrangements may directly cause hybrid sterility and can facilitate speciation by preserving local adaptation in the face of gene flow. We used comparative linkage mapping with shared gene-based markers to identify potential chromosomal rearrangements between the sister monkeyflowers Mimulus lewisii and M. cardinalis, which are textbook examples of ecological speciation. We then re-mapped quantitative trait loci (QTLs) for floral traits and flowering time (pre-mating isolation) and hybrid sterility (post-zygotic isolation). We identified three major...

Data from: Unraveling species concepts for the Helicoprion tooth whorl

Leif Tapanila & Jesse Pruitt
The genus Helicoprion (Chondricthyes: Euchondrocephali) is preserved primarily by a continuous spiral root that forms the base for more than 130 teeth. Helicoprion is found globally in Lower Permian marine rocks and at least 100 specimens exist in public collections worldwide. Ten species of the genus are reviewed in the context of new morphometric analyses conducted on dozens of specimens. Helicoprion whorls share a common inner spiral geometry that results in exponential growth of tooth...

Data from: Behavior and nutritional condition buffer a large-bodied endotherm against direct and indirect effects of climate

Ryan A. Long, R. Terry Bowyer, Warren P. Porter, Paul Mathewson, Kevin Lee Monteith & John G. Kie
Temporal changes in net energy balance of animals strongly influence fitness; consequently, natural selection should favor behaviors that increase net energy balance by buffering individuals against negative effects of environmental variation. The relative importance of behavioral responses to climate-induced variation in costs versus supplies of energy, however, is uncertain, as is the degree to which such responses are mediated by current stores of energy. We evaluated relationships among behavior, nutritional condition (i.e., energetic state), and...
