Tim Grabowski, PhD
Unit Leader - Hawaii Cooperative Fish and Wildlife Research Unit
Research Interests
Tim is interested in the behavioral and physiological ecology of fishes and applying these fields to management and conservation issues. His research tends to focus on the reproductive ecology of fishes as well as local adaptation and population structuring.
Teaching Interests
Tim currently teach field ichthyology and foundations of ecology and conservation biology at Texas Tech University. He also teaches a summer course at the University of Iceland examining the effects of anthropogenic impacts, such as climate change and commercial fisheries, on the marine environment.
Science and Products
Studying the Influence of Streamflow Variability on Fish Populations to Understand Nutrient Transport in Hawaiian and Alaskan Streams in a Changing Climate
Ecosystems spanning the zones from “ridge-to-reef" and “icefield-to-ocean” are home to relatively high levels of biodiversity; serve as conduits of nutrients to sensitive coastal environments; and are culturally and economically important to local communities. These systems are smaller and have unique geological and streamflow properties compared to more typical river systems and, because of this,
Impacts of Extreme Events on the Native and Nonnative Aquatic Species of Hawaiʻi Stream Ecosystem
Freshwater is a critical driver for island ecosystems. Climate change has fundamentally altered the water cycle in tropical islands. The changes in dynamic patterns of streamflow could result in the temporal and spatial difference in the riverine, estuarine, and coastal habitats that support native species. In particular, these habitats support the nine native aquatic species in Hawaiʻi at differe
