Biography

Our laboratory conducts limnological studies related to the restoration or conservation of aquatic ecosystems. My projects include recovering native species, managing nonnative species, understanding the affects of land use change (mining, urbanization, etc) on water quality, and developing natural resource management & conservation plans for the world's largest, freshwater fishes. We recognize that science is critical in developing longer-term, sustainable public policy.

    Abstract
    Lake Tahoe's fishery is among one of the least studied of all the large lakes in the world. Over time there have been a variety of stressors (e.g. introduction of species, eutrophication, nearshore habitat modification), which may have impacted the fishery and only a limited amount of snapshot investigations have been conducted to investigate these impacts or determine the status of a particular species. With little to no information on the status of fishery, in particular the nearshore components where most of the native, littoral fish reside, we have compiled information to determine the status of the nearshore native and non-native fish community and if there are quantifiable indicators and methodologies that can be created to determine the condition of the nearshore fishery. Furthermore, we conducted experiments to determine if ultraviolet radiation (UV) can be used to link nearshore and non-native fish ecology to the physical environment.

    Abstract
    Upland Great Basin meadow ecosystems support regional biodiversity and provide numerous ecosystem services. These meadow systems face numerous forms of degradation and are in need of prioritization for conservation and rehabilitation. Previous work in the Basin broadly illustrates the relationship between aquatic invertebrates and riparian condition. This study examines the aquatic invertebrate community in relation to a riparian meadow processes along a fine spatial and temporal scale. We compared physical, chemical and biological data collected across seasons, within and beyond a meadow reach. For two out of three seasons invertebrate community structure was statistically different across meadow and non-meadow environments. Indicator metrics were temporally inconsistent as a means to identify candidate metrics for a multimetric index. During seasons with higher flows benthic community structure is distinct between a meadow and non-meadow reach. As surface flows decrease, vegetation-groundwater interactions have greater influence on stream conditions and invertebrate populations homogenize across reaches. Understanding the extent of nested population subsets at multiple meadow-streams may be useful in determining the appropriate scale to be examined by indicating distinct populations and, therefore, distinct environmental conditions.
