Research Interests:  My research objectives include asking of how factors intrinsic and extrinsic to aquatic habitats interact and influence the structure and functioning of aquatic ecosystems.  For example, while the transfer of material through food webs is dictated by consumer-resource interactions and/or physical dynamics within the habitat, properties extrinsic to food webs may set a template in which these interactions operate.  Landscape or watershed features coupled with hydrology can play a critical role in both the distribution of species and runoff to ecosystems, which may respectively limit potential food web configurations and productivity.  I also link basic and theoretical research to applied ecosystem management.  A positive and significant outcome of this objective would be to give some resolution to the existing mismatch of the spatial and temporal scales of research and management approaches. 

This research typically straddles the interface of inland aquatic communities and ecosystems.  Research funding is driven by the importance of understanding factors which may compromise surface water and thus aquatic communities and ecosystems.  Within this focus is an emphasis on how human impacts such as hydrological manipulation, nutrient loading, and fish management affect aquatic habitats, populations, and communities.   Recent research methodology includes analysis of large datasets, a broad range of statistical techniques, stable isotope analyses, and enough field sampling of water, habitats, and biota to keep tabs on local conditions.

  Ongoing & Recent Research Projects:

Biological and Habitat Assessment of Ponds in the Kern Water Bank (Kern Water Bank Authority; $50,500, 2017)

Main Qs:  What biological and hydrological variables are associated with waterbird assemblages on the KWB ponds?

How do biological attributes vary spatially in a hydrologically-managed system?

San Joaquin River Floodplain Production & Chinook Salmon Growth (US Bureau of Reclamation;  $990,357, 2013-2016;
Co-PI Joe Merz, Cramer Fish Sciences;)

Main Qs: 

What floodplain attributes best foster juvenile Chinook salmon survival and growth? 

 

How does water management affect this balance?

 

San Joaquin River Predator Study - Salmon Restoration (Fresno Regional Foundation; $23,546- 2013; US Fish & Wildlife Service; $60,000 2013-2014)

 

Main Qs:

How does the probability of predation mortality for juvenile Chinook salmon vary over time and space? 

Are these probabilities more influenced by hydrology, predator movements, or an interaction between the two? 

Habitat and Population Analyses of Delta and Longfin Smelt (Center for California Water Resources Policy and Management; $32,000, 2012-2014)

Main Q:

Are Longfin Smelt populations in the SF Bay-Delta resistant and resilient to variation in freshwater discharge through the system?
