Niche Differentiation in the Dynamics of Host-Symbiont Interactions: Symbiont Prevalence as a Coexistence Problem
(The University of Chicago Press, 2014-04)
Heritable symbioses can have important ecological effects and have triggered important evolutionary innovations. Current predictions for long-term symbiont prevalence are based on their fitness benefits and vertical ...
Global climate cycles and cyclones: consequences for rainfall patterns and lemur reproduction in southeastern Madagascar
(Global Change Biology, 2010)
Mitochondrial DNA Phylogeography of the Norway Rat
(Public Library of Science, 2014)
Central Eastern Asia, foremost the area bordering northern China and Mongolia, has been thought to be the geographic region where Norway rats (Rattus norvegicus) have originated. However recent fossil analyses pointed to ...
Daptomycin Resistance in Enterococci Is Associated with Distinct Alterations of Cell Membrane Phospholipid Content
(Public Library of Science, 2012)
Background: The lipopeptide antibiotic, daptomycin (DAP) interacts with the bacterial cell membrane (CM). Development of DAP resistance during therapy in a clinical strain of Enterococcus faecalis was associated with ...
Conspecific Plasticity and Invasion: Invasive Populations of Chinese Tallow (Triadica sebifera)ﾠHave Performance Advantage over Native Populations Only in Low Soil Salinity
(Public Library of Science, 2013)
Global climate change may increase biological invasions in part because invasive species may have greater phenotypic plasticity than native species. This may be especially important for abiotic stresses such as salt ...
A new social gene in Dictyostelium discoideum, chtB
Background: Competitive social interactions are ubiquitous in nature, but their genetic basis is difficult to determine. Much can be learned from single gene knockouts in a eukaryote microbe. The mutants can be competed ...
Non-Native Plant Litter Enhances Soil Carbon Dioxide Emissions in an Invaded Annual Grassland
(Public Library of Science, 2014)
Litter decomposition is a fundamental ecosystem process in which breakdown and decay of plant detritus releases carbon and nutrients. Invasive exotic plants may produce litter that differs from native plant litter in quality ...
Ontogenetic functional diversity: Size structure of a keystone predator drives functioning of a complex ecosystem
A central challenge in community ecology is to understand the connection between biodiversity and the functioning of ecosystems. While traditional approaches have largely focused on species-level diversity, increasing ...
Plant size and reproductive state affect the quantity and quality of rewards to animal mutualists
(British Ecological Society, 2014)
Many plants engage ants in defensive mutualisms by offering extrafloral nectar (EFN). Identifying sources of variation in EFN quantity (amount) and quality (composition) is important because they can affect ant visitation ...
Timing and Scope of Genomic Expansion within Annelida: Evidence from Homeoboxes in the Genome of the Earthworm Eisenia fetida
(Oxford University Press, 2015)
Annelida represents a large and morphologically diverse group of bilaterian organisms. The recently published polychaete and leech genome sequences revealed an equally dynamic range of diversity at the genomic level. The ...
