Dynamics of coastal meta-ecosystems: the intermittent upwelling hypothesis and a test in rocky intertidal regions

Creator:: Menge, Bruce A. and Menge, Duncan N. L.
Abstract:: The intermittent upwelling hypothesis (IUH) predicts that the strength of ecological subsidies, organismal growth responses, and species interactions will vary unimodally along a gradient of upwelling from persistent downwelling to persistent upwelling, with maximal levels at an intermediate or ‘‘intermittent’’ state of upwelling. To test this model, we employed the...

Comparative behavior of red lionfish Pterois volitans on native Pacific versus invaded Atlantic coral reefs

Creator:: Cure, Katherine, Benkwitt, Cassandra E., Kindinger, Tye L., Pickering, Emily A., Pusack, Timothy J., McIlwain, Jennifer L., and Hixon, Mark A.
Abstract:: Pacific red lionfish Pterois volitans have invaded Atlantic reefs and reached much greater population densities than on native reefs. We hypothesized that lionfish on invaded reefs would (1) experience higher kill rates and thus spend less time hunting, given the naïveté of Atlantic prey, (2) consume a greater variety of...

Host species composition influences infection severity among amphibians in the absence of spillover transmission

Creator:: Han, Barbara A., Kerby, Jacob L., Searle, Catherine L., Storfer, Andrew, and Blaustein, Andrew R.
Abstract:: Wildlife epidemiological outcomes can depend strongly on the composition of an ecological community, particularly when multiple host species are affected by the same pathogen. However, the relationship between host species richness and disease risk can vary with community context and with the degree of spillover transmission that occurs among co-occurring...

Host Specificity Among Closely Related Dinoflagellates: Using Autofluorescence to Enumerate Symbionts in Aiptasia

Creator:: Corey, Kevin R., Kirk, N. L., Meyer, E., Coffroth, M. A., and Weis, V. M.
Abstract:: Symbiotic relationships between cnidarians and dinoflagellates within the genus Symbiodinium are critically important for the success of coral reefs. These symbionts provide their hosts with photosynthetically-fixed carbon in exchange for nutrients and shelter. Symbiodinium is a phylogenetically diverse genus that is often typed by sequencing the ribosomal internal transcribed spacer...

Do lagoon physiography and hydrology determine the physico-chemical properties and trophic status of coastal lagoons? A comparative approach

Creator:: Roselli, L., Canedo-Argueelles, M., Costa Goela, P., Cristina, S., Rieradevall, M., D'Adamo, R., and Newton, A.
Abstract:: Coastal lagoons are very heterogeneous systems covering a wide range of physiographical and hydrological characteristics. The hypothesis of the present investigation was to test physiographical and hydrological characteristics of coastal lagoons affecting their physico-chemical properties and their buffer capacity against nutrient enrichment. We compared data collected during a whole annual...

Effective size of a wild salmonid population is greatly reduced by hatchery supplementation

Creator:: Christie, M. R., Marine, M. L., French, R. A., Waples, R. S., and Blouin, M. S.
Abstract:: Many declining and commercially important populations are supplemented with captive-born individuals that are intentionally released into the wild. These supplementation programs often create large numbers of offspring from relatively few breeding adults, which can have substantial population-level effects. We examined the genetic effects of supplementation on a wild population of...

Identification of biomarkers indicative of barotrauma and recovery in black rockfish Sebastes melanops

Creator:: Pribyl, A. L., Schreck, C. B., Parker, S. J., and Weis, V. M.
Abstract:: A Sebastes-specific complementary DNA (cDNA) microarray was developed to identify potential biomarkers involved in the capture stress and recovery of Sebastes species if they are assisted in returning to their original depth of capture following barotrauma. Black rockfish Sebastes melanops were exposed to simulated decompression from 450 kPa (c. 35...

More than a meal… integrating non-feeding interactions into food webs

Creator:: Kefi, Sonia, Berlow, Eric L., Wieters, Evie A., Navarrete, Sergio A., Petchey, Owen L., Wood, Spencer A., Boit, Alice, Joppa, Lucas N., Lafferty, Kevin D., Williams, Richard J., Martinez, Neo D., Menge, Bruce A., Blanchette, Carol A., Iles, Alison C., and Brose, Ulrich
Abstract:: Organisms eating each other are only one of many types of well documented and important interactions among species. Other such types include habitat modification, predator interference and facilitation. However, ecological network research has been typically limited to either pure food webs or to networks of only a few (<3) interaction...

Flow Management for Hydropower Extirpates Aquatic Insects, Undermining River Food Webs

Creator:: Kennedy, Theodore A., Muehlbauer, Jeffrey D., Yackulic, Charles B., Lytle, David A., Miller, Scott W., Dibble, Kimberly L., Kortenhoeven, Eric W., Metcalfe, Anya N., and Baxter, Colden V.
Abstract:: Dams impound the majority of rivers and provide important societal benefits, especially daily water releases that enable on-peak hydroelectricity generation. Such “hydropeaking” is common worldwide, but its downstream impacts remain unclear. We evaluated the response of aquatic insects, a cornerstone of river food webs, to hydropeaking using a life history–hydrodynamic...

Larval exposure to predator cues alters immune function and response to a fungal pathogen in post-metamorphic wood frogs

Creator:: Groner, Maya L., Buck, Julia C., Gervasi, Stephanie, Blaustein, Andrew R., Reinert, Laura K., Rollins-Smith, Louise A., Bier, Mark E., Hempel, John, and Relyea, Rick A.
Abstract:: For the past several decades, amphibian populations have been decreasing around the globe at an unprecedented rate. Batrachochytrium dendrobatidis (Bd), the fungal pathogen that causes chytridiomycosis in amphibians, is contributing to amphibian declines. Natural and anthropogenic environmental factors are hypothesized to contribute to these declines by reducing the immunocompetence of...
