The geography of parasite local adaptation to host communities

Emily Bellis, Chloee McLaughlin, Claude DePamphilis & Jesse Lasky
Fitness responses to environment can shape species distributions, though opposing eco-evolutionary processes can obscure environmental effects. For example, host specificity influences parasite dynamics, but is unclear how adaptation of parasites to local host communities may scale up to continental distributions. Here, we develop a macroecological framework to determine how host community structure affects the distribution of specialist and generalist populations of Striga hermonthica, an African parasitic plant of cereal crops. Combining data from global crop...

Evidence of nest material kleptoparasitism in Worm-eating Warblers (Helmitheros vermivorum) in east-central Arkansas, USA

Amy Wynia & James Bednarz
Nest material kleptoparasitism likely evolved in birds to reduce the cost of searching for and collecting material themselves. Although nest material kleptoparasitism has been reported commonly in colonially nesting species, reports for solitary breeding species are infrequent, especially for neotropical migratory species. Here we report potential and actual nest material kleptoparasitism in the Worm-eating Warbler (Helmitheros vermivorum). We deployed video camera systems at passerine nests (n = 81) in east-central Arkansas during summers 2011–2012. In...

Conservation genetic assessment of the paleback darter (Etheostoma pallididorsum), a narrowly distributed endemic in the Ouachita Highlands, Arkansas, USA

Brittany McCall & Brook Fluker
The Paleback Darter is considered imperiled and has recently been petitioned for listing under the Endangered Species Act. Prior allozyme-based studies found evidence of small effective population size, warranting conservation concern. The objective of this study was to assess population dynamics and the phylogeographic history of the Paleback Darter, using a multilocus microsatellite approach and mitochondrial DNA. The predictions of this study were that Paleback Darter populations will exhibit low genetic diversity and minimal gene...

Functional connectivity in a continuously distributed, migratory species as revealed by landscape genomics

Melanie E. F. LaCava, Roderick B. Gagne, Kyle D. Gustafson, Sara J. Oyler-McCance, Kevin L. Monteith, Hall Sawyer, Matthew J. Kauffman, Daniel J. Thiele & Holly B. Ernest
Maintaining functional connectivity is critical for the long-term conservation of wildlife populations. Landscape genomics provides an opportunity to assess long-term functional connectivity by relating environmental variables to spatial patterns of genomic variation resulting from generations of movement, dispersal, and mating behaviors. Identifying landscape features associated with gene flow at large geographic scales for highly mobile species is becoming increasingly possible due to more accessible genomic approaches, improved analytical methods, and enhanced computational power. We characterized...
