Greg Hayward, PhD
ENRI Research Affiliate Professor


PH: 907.743.9537

Greg Hayward, Regional Wildlife Ecologist with the U.S. Forest Service in Alaska, is a population ecologist with a passion for helping resource managers understand the trade-offs associated with difficult land management decisions.  As a conservation practitioner, Greg brings an academic perspective from faculty positions at the University of Idaho and the University of Wyoming to his work on federal land management.  Greg’s research interests extend from boreal owls and flying squirrels to Amur tigers and cutthroat trout, with a focus on the consequences of broad-scale ecological disturbance on wildlife dynamics.  His approach to life developed most during the six years in which he lived and conducted research in the wilderness of central Idaho with his wife, Pat.

Research Specialty: Hilderbrand specialized in large mammal ecology and physiology with a special emphasis on predators.  Additional interests include population dynamics and predator-prey interactions.  He currently serves on several Service-wide National Park Service panels, as president-elect of the Alaska Chapter of The Wildlife Society, as Associate Editor of Ursus, and as a peer reviewer for more than ten international research journals and the National Science Foundation.

Thomas Kline, Jr., PhD
ENRI Research Affiliate Professor

Oceanographer & Limnologist
Prince William Sound Science Center

Research Specialty: Kline specializes in ecosystem and food web analysis using the stable isotopic and energetic content of biota. His goal is to better understand the ecology of fishes by using their chemical properties. In particular, how environmental fluctuations and ecological interactions drive fish recruitment and how fish, especially semelparous species, can drive fluctuations of their environment.

Research Activities:

  • Prince William Sound Herring survey:  Pacific herring energetic recruitment factors, supported by the EVOS Trustee Council
  • A high temporal and spatial resolution study to validate the separate herring condition monitoring program, supported by the EVOS Trustee Council
  • Herring condition monitoring, supported by the EVOS Trustee Council
  • Marine derived nutrients, supported by the EVOS Trustee Council
  • A long-term observation program using natural stable isotope abundance for detecting coastal Gulf of Alaska zooplankton source fluctuations in fishes, supported by the National Science Foundation
  • Stable isotope-based spatial and ontogenetic variability in the trophic status of Pacific halibut, supported by the International Pacific Halibut Commission
