"Alpine thermal dynamics and associated constraints on the behavior of mountain goats in Southeast Alaska"

Jeff Frederick, UAF

Abstract: Alpine Caprinae including mountain goats (Oreamnos americanus) have been described to be sensitive to temperature changes within their summer range and consequently, may be forced to select habitats which allow for the maintenance of a stable core temperature on warm days. Additionally, mountain goats must spend a substantial portion of their time actively foraging in summer. The low abundance of high quality food at high elevation sites coupled with the energetic cost of accessing these areas could have adverse effects on survival if too much time is spent on thermoregulatory habitat selection. This study aims to investigate mountain goat behavioral activity budgets across alpine temperature gradients in Southeast Alaska. We monitored summer mountain goat behavior in the Berners Bay area using both focal animal sampling and scan sampling techniques to compare the duration of time spent on specific behaviors and the proportion of behaviors exhibited by the animals on warm and cool days. Coupled with our behavioral investigations, we simultaneously monitored elevational temperature gradients using meteorological stations and an array of passive temperature loggers. By deriving near-surface lapse rates from our temperature data, we aim to demonstrate the utility of downscaled, region specific temperature-elevation profiles for ecological applications rather than making inferences based on broad spatial models. Given current warming trends and projections of changing climate regimes being more pronounced at higher latitudes, there is a marked need to better understand thermoregulatory constraints on faunal behavior and the effect of changing landscapes on the distributions and survival wildlife populations in Alaska.

UAF Science Communication Event

Silverbow Bakery, 120 Second St., Juneau

"Cod Chronicles and Salmon Stories: How Alaskan Scientists Solve Mysteries of the Wild"

Cod Chronicles and Salmon Stories will feature presentations and a panel discussion by UAF graduate students and local scientists who are investigating Alaska’s spectacular diversity of fish and wildlife. The series of short talks will highlight a cross section of current research by Juneau scientists, from the use of innovative techniques for detecting stressed out salmon to the important role of cod in the rapidly changing Arctic Ocean. The speakers will share their discoveries about what is causing declines in the size of halibut and how to estimate the number of fish that survive in the ocean each year. They will provide perspectives on the effects of a changing environment on the growth of young salmon and the spread of disease in bats. Please visit the Silverbow Bakery to meet these young investigators and learn about their adventures at sea and in the laboratory, what they’ve learned so far, and how the public can stay informed about their future findings. Admission to the event is free and refreshments will be served. All ages are welcome.

ACRC Spring Semester Brown Bag Lecture Series

The Alaska Coastal Rainforest Center is hosting a Brown Bag Lunchtime Lecture series during the spring semester. Talks will be on Wednesdays from noon—1pm at the Forestry Sciences Lab adjacent to the UAS Juneau campus. The lunchtime speaker series is meant to be an informal avenue for graduate students, faculty, and professionals to present new and existing research and scholarship, brainstorm ideas, and have the opportunity to receive feedback in an informal setting.  We invite all interested persons to join us to learn about the exciting research projects and collaborations that are happening in Southeast Alaska.

2015 is the International Year of Soils.  This finite natural resource is important for food security and the ecosystem.  One Wednesday each month will focus on soils science to help raise awareness and promote the sustainability of our limited soil resources.
