Animals move through landscapes where their resources are unevenly and often patchily distributed. When animals move and choose among their scattered resources in predictable ways, ecologists may be able to anticipate the spatial...
The study of adaptive molecular evolution in natural populations has been severely limited by the difficulty of linking genetic variation to phenotypic variation to fitness effects. Most studies connecting genotype, phenotype, and...
Comparing patterns of spatial genetic structure across co-distributed species is critical to making inferences about the factors influencing population divergence, persistence, and change over time. The fields of phylogenetics and...
Our knowledge of the reproductive dynamics of many economically important marine fish species is remarkably poor. This limits our ability to assess and manage the effects of exploitation on their reproductive potential. The Gulf Black...
Fertilization is a complex process, and gamete traits can affect the rate at which sperm and egg collide and fuse, making them prime targets for selection. This is particularly true for broadcast spawners, whose fertilization success...
Density, or the number of individuals per unit area, is known to have substantial effects on individual organisms and on populations. In particular, densities at small spatial scales often affect species interactions, e.g., predation and...
The effective conservation of threatened and endangered plants requires an understanding of population dynamics and the evaluation of factors that could reduce population growth. I constructed and analyzed a stage structured demographic...
Most mega-biodiverse countries have low to upper middle incomes (Fisher and Christopher 2007), resulting in a shortage of funding and expertise to implement conservation actions in these biodiversity hotspots. Creating conservation...
A long-standing paradox in evolutionary biology is the maintenance of genetic variation in traits that are strongly tied to fitness. How is it that variation can be maintained in ecologically important traits when directional selection...
Understanding the maintenance of phenotypic variation within populations has long been a puzzle in evolutionary biology. Many models ignore that fact that animals are not living alone; instead social factors have the potential to alter...
A thorough understanding of the physiology of elasmobranchs (sharks, skates, and rays) is important from an applied aspect as most species are captured either directly or indirectly in commercial and recreational fisheries, or affected...
The North American gray treefrog complex (Hyla versicolor sensu lato), defined here as encompassing the diploid species Hyla chrysoscelis and Hyla avivoca, and the tetraploid Hyla versicolor, has long been used as a model system in a...
Coastal areas serve as vital habitat for many marine fishes. Estuaries are a type of coastal system in which freshwater input often drives broad gradients of environmental variables while transporting fluvial nutrient subsidies to marine...
Sponges form symbioses with a wide array of mesofauna including polychaetes, crustaceans, brittle stars, and bivalves. These organisms use the sponge for food and shelter, but their effect on the sponge is largely unknown. The...
Quantitative genetics is a powerful tool for predicting phenotypic evolution on a microevolutionary scale. This predictive power primarily comes from the Lande equation (Δz̅=Gβ), a multivariate expansion of the breeder's equation, where...
The effect of changing anthropogenic mercury emissions on marine wildlife is of broad interest. Methylmercury can cause reproductive and neurological damage and biomagnifies in food webs. Mercury availability in the Pacific Ocean has...
Drivers of animal movement, including abiotic factors such as environmental conditions or climate and biotic factors such as species interactions and reproduction, are classic topics in ecology and relevant to both basic and applied...
The ecological and evolutionary factors influencing whether hermaphrodites inbreed or outbreed via self-fertilization or outcrossing has long been a theoretical and empirical focus. Recent theory predicts that the conditions favoring the...
