Data from: Environmental heterogeneity has a weak effect on diversity during community assembly in tallgrass prairie

Sara G. Baer, John M. Blair & Scott L. Collins
Understanding what constrains the persistence of species in communities is at the heart of community assembly theory and its application to conserving and enhancing biodiversity. The “environmental heterogeneity hypothesis” predicts greater species coexistence in habitats with greater resource variability. In the context of community assembly, environmental heterogeneity may influence the variety and strength of abiotic conditions and competitive interactions (environmental filters) to affect the relative abundance of species and biodiversity. We manipulated key resources that...

Data from: Purple pitcher plant (Sarracenia rosea) dieback and partial community disassembly following experimental storm surge in a coastal pitcher plant bog

Matthew J. Abbott & Loretta L. Battaglia
Sea-level rise and frequent intense hurricanes associated with climate change will result in recurrent flooding of inland systems such as Gulf Coastal pitcher plant bogs by storm surges. These surges can transport salt water and sediment to freshwater bogs, greatly affecting their biological integrity. Purple pitcher plants (Sarracenia rosea) are Gulf Coast pitcher plant bog inhabitants that could be at a disadvantage under this scenario because their pitcher morphology may leave them prone to collection...

Data from: Molecular phylogenetics of Kosteletzkya (Malvaceae, Hibisceae) reveals multiple independent and successive polyploid speciation events

Kurt M. Neubig, , W. Mark Whitten, Stuart F. McDaniel & Orland J. Blanchard
Kosteletzkya s.s. is a genus of 17 species (excluding the endemic species of Madagascar), found in the New World, continental Africa, Madagascar, and Southeast Asia. Recent chromosome counts revealed diploid, tetraploid, and hexaploid species. To estimate the history of the genus, we sequenced nuclear and plastid loci for nearly all Kosteletzkya spp., in the majority of cases, with multiple accessions per species. The African species form a paraphyletic grade relative to a New World clade....

Data from: Intraspecific variation of a dominant grass and local adaptation in reciprocal garden communities along a US Great Plains’ precipitation gradient: implications for grassland restoration with climate change

Loretta Johnson, Jacob T. Olsen, Hannah Tetreault, Nora M. Bello, Angel DeLaCruz, Johnny Bryant, Theodore J. Morgan, Mary Knapp, Sara G. Baer, Brian R. Maricle & Loretta C. Johnson
Identifying suitable genetic stock for restoration often employs a ‘best guess’ approach. Without adaptive variation studies, restoration may be misguided. We test the extent to which climate in central US grasslands exerts selection pressure on a foundation grass big bluestem (Andropogon gerardii), widely used in restorations, and resulting in local adaptation. We seeded three regional ecotypes of A. gerardii in reciprocal transplant garden communities across 1150 km precipitation gradient. We measured ecological responses over several...
