Marine fish diversification along the water column gradient: a tale of many threads
(2022-08-04)
Decades of investigation about the evolutionary mechanisms responsible for the astonishing diversity of fishes have suggested habitat transitions along the water column as a prominent ecological divergence axis affecting ...
Subsidy intermediaries: the role of aquatic plants in storing and transferring resources from aquatic biogeochemical hotspots to terrestrial ecosystems
(2022-05-13)
The roles mobile animals and abiotic processes play as vectors for resource transfers between ecosystems (subsidies) are well-studied. Trophic interactions between mobile animals and their food sources often convey subsidies ...
Looking out for the little guys: how mussels facilitate microbes and scientists facilitate students
(2022-12-16)
Animals can have large impacts on how ecosystems function, from influencing population dynamics of other plant or animal species, to modifying hydrogeological flow dynamics. One ecosystem function that has received widespread ...
Experimenting with multistressors: intraspecific variation in behaviors, tolerances, and distributions
(2020-12-18)
Understanding organisms’ behavioral, spatial, and physiological responses to stress is critically important for successfully predicting and managing population declines and extinctions. Currently, climate change is ...
Ground-nesting birds in a changing climate: case studies of proximate behavioral mechanisms used by skimmers and terns to address seasonal variation in resources
(2022-12-16)
Understanding how species will adapt to anthropogenic climate change is one of the greatest challenges for ecologists and evolutionary biologists. For organisms with low dispersal abilities, rapid adaptation will often be ...
Response of native prey species to an exotic invasive predator: Ecology and evolution of inducible defenses
(2021-05-14)
One of the most common and devastating human impacts on the world’s ecosystems is the introduction of non-native invasive species which can negatively impact agriculture, industry, human health, and the natural environment. ...
Interaction of climate and space in variation of the functional niche of freshwater mussels (Family: Unionidae)
(2020-05-08)
Animals are an integral part of ecosystems: they consume and process materials, thus connecting the cycling of nutrients and matter through ecosystems. Freshwater mussels (order Unionoida) are a diverse group of bivalve ...
Demographic and behavioral characteristics of wintering sparrow populations in a South Carolina salt marsh
(2023-12-15)
Throughout the world, coastal communities both human and natural face the existential threat of rapidly rising seawater levels resulting from global climate change. Since 2012, my collaborators and I have been monitoring ...
Why are there so many birds in the tropics: using comparative approaches to investigate the confluence of landscape, ecology, and genome in the generation of Neotropical avian diversity
(2022-12-16)
The Neotropics are home to an astonishing level of avian diversity, and thus naturally a focus for the study of the generation of biodiversity. Studies of tropical speciation often focus on large-scale landscape changes, ...
An integrative ecological and evolutionary genomic study of lake Daphnia across time
(2023-05-12)
An undisputable fact of the modern age is that human activities are now a major force shaping the biosphere. Some have called for a new geological epoch called the “Anthropocene” or the age of humans— the search is underway ...
