My two main areas of research are cross-habitat resource subsidies, especially aquatic subsidies to terrestrial ecosystems, and the ecology and conservation of amphibians. I am interested in exploring the effects of spatial subsidies on population dynamics and trophic interactions in recipient coastal and riparian ecosystems. I am currently involved in projects aimed at assessing conservation threats in several foothill and high-elevation frogs from California and the eastern slopes of the Andes.

My overall interests include freshwater ecology of streams, lakes, reservoirs, and wetwalls, especially benthic communities & fresh water algae. In particular I am interested in algal biodiversity, the application of algal taxonomy to answer ecological questions, and exploring how algae are drivers and indicators of ecosystem structure and function. Recent research has focused on the taxonomy and ecology of the acidophilic diatom Eunotia (Contact me if you have some interesting Eunotia taxa!!). Currently, I am exploring photogrammetric assessment of algae to determine ecologically significant variation in algal assemblages at watershed scales and the ecosystem contributions of Nostoc (Cyanobacteria) and its associated midge across different watershed scales.

My research is focused on the ecology of environmental biofilms. I am interested in understanding the strength and nature of interactions that take place among biofilm community members. Currently I am examining how bacterial-algal interactions in epilithic biofilms change according to light and nutrient availability at different drainage network positions in a stream ecosystem.

Mike Limm, Graduate Student
 My primary interest is understanding how the physical characteristics of a drainage network influence the way carbon and nutrients move through and between terrestrial and aquatic communities. My current focus is on hydrologic and hydraulic controls on food webs and the influence of food web composition on ecosystem processes. I also like fish.

I study the effects of hydropower facilities on aquatic resources in California rivers. The river breeding Foothill yellow legged frog, Rana boylii is a sentinel species in this effort.  I focus on flow velocity and water temperature as the key abiotic conditions influencing frog populations.  My approach combines field experiments, long term monitoring, and population modeling. The work is supported by the Public Interest Energy Research Program of the California Energy Commission.  (http://animalscience.ucdavis.edu/PulsedFlow/Kupferberg%202007%20b.pdf)

My main research interest is the role of aquatic ecosystems (rivers and wetlands) as subsidies sources in the matrix of drier landscapes. Specially, how vertebrates, birds and bats, make preferential use of them regarding to purely terrestrial habitats. I like using automated field monitoring as a way to know what exactly is happening on real time. I am also interested in knowing the driving variables that make restoration projects succeed or fail, especially, wetland restoration projects. Finally, I am also interested in bird population dynamics under intense human influence.

My research focuses on the transport and effects of chemicals and nutrients through aquatic ecosystems. In particular, I am interested in how chemicals in freshwater systems affect biota locally, how much downstream transport occurs, and what the effects are in the marine environment. To study these questions, I work on pyrethroid pesticides in three rivers in the Monterey Bay area, and Epithemia in the Eel River of California.

Trophic exchange between terrestrial and aquatic communities in riparian habitats, landscape and seasonal patterns of prey production and bat community foraging activity along drainage networks; food web tracers; bat phylogeography and conservation biology.

Jack Sculley, Graduate Student
My main research interests center around what traits induce stability or instability in communities, particularly with respect to climatic disturbance and changes in disturbance regimes over long time-scales. A topic of major interest is how mutualisms expand species constraint envelopes--e.g. corals can colonize nutrient-poor tropics, redwoods can colonize dry climates by using fungi to tap fog water (apparently) etc.--and how the flip side may be vulnerability to disturbance and/or climate change. I am interested in how species interactions effects at the food-web/community level scale-up over larger spatial and temporal scales to impact biogeographic distributions, and similarly how climatic processes scale-down to ecological time and space scales. I am considering redwoods and their endosymbiotic fungi as a sample system to model computationally, and compare with field experiments and paleo-ecological data.
