Assessing the influence of traits and environment on the nutritional value of small pelagic species in the California Current
DownloadFall 2024
Marine food webs are increasingly disrupted by climate change, with implications for fisheries management. Understanding how changing ocean conditions are likely to affect the nutritional quality of prey species that predators depend on could assist with predicting population responses. Here we...

Beneath the Surface: sub-lethal effects of parasites and pollutants on mammal energetics and implications for aquatic ecosystems.
DownloadFall 2023
Sub-lethal infections by helminth parasites are generally considered unimportant for wildlife fitness. However, data on the sub-lethal effects of parasites, combined with the effects of anthropogenic stressors, are often lacking. To fill this gap in knowledge, I carried out a meta-analysis of the...

Disentangling the relative effects of structural complexity and substrate composition on fish habitat selection in coral reef environments
DownloadFall 2021
Identifying features of biogenic habitats (i.e. made of living plants and animals) that attract and retain resident species is a key theme in ecology with important implications for habitat conservation and restoration. Using corals (class Anthozoa, phylum Cnidaria) —a group of foundational...

Fall 2023
Global change is altering ecological communities and the food webs they support, reducing food web persistence. While a variety of features likely impact the dynamics of perturbed food webs, the relative importance of intrinsic factors (i.e. characteristics of the food web itself) and extrinsic...
