Nathan Borg, Michael S. Mitchell, Paul M. Lukacs, Curt M. Mack, Lisette P. Waits, Paul R. Krausman
2017, Journal of Wildlife Management (81) 38-45
Connectivity is important for population persistence and can reduce the potential for inbreeding depression. Connectivity between populations can also facilitate disease transmission; respiratory diseases are one of the most important factors affecting populations of bighorn sheep (Ovis canadensis). The mechanisms of connectivity in populations of bighorn sheep likely have implications...
Spatio-temporal development of vegetation die-off in a submerging coastal marsh
Lennert Schepers, Matt L. Kirwan, Glenn R. Guntenspergen, Stijn Temmerman
2017, Limnology and Oceanography (62) 137-150
In several places around the world, coastal marsh vegetation is converting to open water through the formation of pools. This is concerning, as vegetation die-off is expected to reduce the marshes' capacity to adapt to sea level rise by vegetation-induced sediment accretion. Quantitative analyses of the spatial and temporal development...

Megan K. LaPeyre, Lindsay Schwarting Miller, Shea Miller, Earl Melancon
2017, Book chapter, Living shorelines: The science and management of nature-based coastal protection
Coastal erosion threatens many low-lying areas around the globe. Rising sea levels from climate change are expected to increase coastal erosion and exacerbate flooding and storm surges. This is particularly true in low-lying coastal Louisiana, which developed as the Mississippi River changed course (delta switching) over the past 7000 years....

Andrew R. Wargo, Robert J. Scott, Benjamin Kerr, Gael Kurath
2017, Virus Research (227) 200-211
Viral replication and shedding are key components of transmission and fitness, the kinetics of which are heavily dependent on virus, host, and environmental factors. To date, no studies have quantified the shedding kinetics of infectious hematopoietic necrosis virus (IHNV) in rainbow trout (Oncorhynchus mykiss), or how they are associated with...
Mudflat morphodynamics and the impact of sea level rise in South San Francisco Bay
Mick Van der Wegen, Bruce E. Jaffe, Amy C. Foxgrover, Dano Roelvink
2017, Estuaries and Coasts (40) 37-49
Estuarine tidal mudflats form unique habitats and maintain valuable ecosystems. Historic measurements of a mudflat in San Fancsico Bay over the past 150 years suggest the development of a rather stable mudflat profile. This raises questions on its origin and governing processes as well as on the mudflats’ fate under scenarios...
