Population Assessments of the Pacific Sheath-Tailed Bat and Mariana Swiftlet
Using thermal cameras, we are determining the population size and cave occupancy of the Mariana swiftlet and Pacific sheath-tailed bat. Both species face extirpation from the Northern Mariana Islands and are listed as endangered. Understanding the species' population status can assist in planning recovery efforts for both species.
Pacific Island Bird Survey Design and Data Analysis
Abundance data are collected for bird populations throughout the Pacific Islands by numerous federal, state, university, and non-profit organizations. In order to ensure data are standardized and available to researchers throughout the region, interagency bird databases have been created and continue to be used. These databases contain more than a million compiled, proofed, and standardized...
Invader Removal and Recovery of a Threatened Amphibian
The Herpetological Research Team is using acoustic surveys and eDNA methods to evaluate the progress of invasive bullfrog removal and Oregon spotted frog recovery.
Acoustic Surveys to Inform Invasive American Bullfrog Removal Efforts
The Herpetological Research Team is recording audio in areas where American bullfrogs have invaded to learn more about where and when they are breeding and inform managers tasked with controlling their spread.
Conservation Genetics of the Hawaiian Hoary Bat
The Hawaiian Hoary Bat ( Lasiurus semotus ) or ʻōpeʻapeʻa is the only extant land mammal native to the Hawaiian archipelago and is listed as endangered due to apparent population declines, and a lack of knowledge concerning its distribution, abundance, and habitat needs. This study is designed to apply molecular techniques to document demographic information, assess genetic variability, describe...
Post Fire Restoration in Hawai‘i Volcanoes National Park
We are studying post-fire forest regeneration in montane habitats within Hawaiʻi Volcanoes National Park. By testing out different restoration strategies, as well as links between grass cover and fire, we hope to increase restored forest fire resistance and resilience.
Fisher Restoration on the Olympic Peninsula
Researchers at the Forest and Rangeland Ecosystem Science Center, Olympic Field Station, have been involved in fisher restoration to Washington’s Olympic Peninsula since 2008, when fishers were reintroduced to the peninsula following decades of extirpation.
Identifying Genetic Diversity of Wolbachia Bacteria for Mosquito Control
We are sequencing the DNA of Wolbachia bacteria found in mosquito populations in Hawai’i and those used for mosquito control. We are also developing sample processing techniques to increase the efficiency and accuracy of monitoring mosquito control efforts to help long-term survival and restoration of Hawaiian forest bird populations.
Chemical Ecology of Rapid ʽŌhiʽa Death
We are working on understanding the chemical ecology of Rapid ʽŌhiʽa Death - ROD -, which is critical for protecting both healthy and ROD-infected ʽōhi‘a. A better understanding could lead to early ROD detection tools and the development of attractants and repellents to manipulate ambrosia beetle populations.
Movement Patterns of the Endangered Hawaiian Hawk
To document movement patterns and habitat use of Hawiian Hawks, GPS tags were attached to 17 individuals to track their movement across continuous, fragmented, and urban landscapes. We are now gathering multi-year tracking data to assess key aspects of habitat needs, and how these birds navigate through different ecosystems.
Bat Ecology in Western Washington's National Parks
The expansion of the bat fungal disease White-Nose Syndrome (WNS) to the Pacific Northwest is centered in western Washington. However, not much is known about bat distribution and activity in and around Washington’s National Parks.
Developing Planting Designs for Forest Restoration
We are testing different planting mixtures and densities to refine restoration efforts in the Hakalau Forest National Wildlife Refuge.
