Journal ArticleDOI
Host and parasite thermal ecology jointly determine the effect of climate warming on epidemic dynamics
TL;DR: Experiments and modeling demonstrate that vital rates of a host and parasite respond differently to temperature, with local parasite extinction in the coastal southeastern United States predicted under climate warming, and highlights the need to measure host and parasites thermal performance to predict infection responses to climate change.
Journal ArticleDOI
Generalizing Ecological Effects of Shoreline Armoring Across Soft Sediment Environments
Jenifer E. Dugan,Kyle A. Emery,Kyle A. Emery,Merryl Alber,Clark R. Alexander,James E. Byers,Alyssa-Lois M. Gehman,Natalie A. McLenaghan,S. E. Sojka +8 more
TL;DR: The authors developed a conceptual model that scales predicted ecological effects of shore-parallel armoring based on two axes: engineering purpose of structure (reduce/slow velocities or prevent/stop flow of waves and currents) and hydrodynamic energy (e.g., tides, currents, waves) of soft sediment environments.
Journal ArticleDOI
Cyanobacterial distributions along a physico‐chemical gradient in the Northeastern Pacific Ocean
Sebastian Sudek,R. Craig Everroad,Alyssa-Lois M. Gehman,Jason M. Smith,Camille Poirier,Francisco P. Chavez,Alexandra Z. Worden,Alexandra Z. Worden +7 more
TL;DR: The phylogenetic precision of the 16S rRNA gene analytical approach and depth of bar-coded sequencing facilitated detection of clades at low abundance in unexpected places, including Prochlorococcus at the coast and Cyanobium-related sequences offshore, although it remains unclear whether these came from resident or potentially advected cells.
Journal ArticleDOI
Non-native parasite enhances susceptibility of host to native predators.
TL;DR: The preferential consumption of L. panopaei-infected prey by C. sapidus highlights how interactions between organisms could affect where novel parasites are able to thrive.
Journal ArticleDOI
Predators, environment and host characteristics influence the probability of infection by an invasive castrating parasite
Alyssa-Lois M. Gehman,Jonathan H. Grabowski,A. Randall Hughes,David L. Kimbro,Michael F. Piehler,James E. Byers +5 more
TL;DR: It is demonstrated that in addition to host characteristics, biotic and abiotic community-level variables both serve as large-scale indicators of parasite dynamics, including predator abundance and the depth of water inundation over reefs at high tide.
