The Tundra in Transition Webinar by Don Spalinger Presented by Don Spalinger & Nathan WolfThis seminar focuses on our concepts of regulation of nutrient flows through tundra ecosystems and the effect that climate (or weather) has on these processes. Nutrient flow and climate, in turn, should regulate plant phenology and production, and thus caribou behavior and nutrition. We will present some ideas for assessing the landscape patterns of these processes and monitoring their impacts. Finally, we will provide examples of such assessment and monitoring processes from our work in Western Alaska over the past two years.​ Categories: Data; Tags: ALPINE/TUNDRA, ALPINE/TUNDRA, CARBON, CARBON, CARBON CYCLE/CARBON BUDGET MODELS, All tags...

One of those concerns is that the majority of caribou herds throughout the circumpolar north are declining, perhaps as a result of climate change. The principal objective of this research is to reveal the connections between soil nutrient cycling, forage quality and caribou habitat selection. This framework is underpinned by the concept that tundra ecosystem productivity is ultimately driven by the thermodynamics of the system induced by climate.

Existing data describe MCH harvests, herd movements, and caribou abundance through time, but an investigation drawing from traditional ecological knowledge (TEK) has not occurred. This project will integrate TEK with existing knowledge of caribou movements and subsistence harvests. Targeted stakeholders include local tribes, including Bristol Bay Native Association (BBNA), local village councils, the United States Fish and Wildlife Service, Lake Clark National Park and Preserve (LCNP), and...

Poor snow conditions lower the sightability of moose, yet, for most regions of Alaska, the variation in moose sightability during suboptimal conditions has not yet been quantified. Because scientists are predicting less snowfall in this region over the long term, we initiated research to estimate sightability correction factors (SCF_c) using radiocollared animals to apply to abundance estimates obtained via the GeoSpatial Population Estimator (GSPE) method. The Project Goal is to develop a model that...

Climate projections for the archipelago indicate probable increases in annual and seasonal air temperature over the next 85 years. Corresponding increases in the temperature of freshwaters also are expected, which may adversely influence the biology of salmon, the quality of salmon habitat, and the availability of salmon to support the ecosystem and economy. It is essential that salmon managers be provided with relevant and reliable information on expected changes in thermal regimes and their influence...

This research is a collaborative effort among the principal managers of this resource to directly address the causes of this decline.The goals of this project was to mechanistically link climate, soil N cycling, plant morphological and nutritional phenology, and caribou population dynamics, by collecting high-quality information to knit together ecosystem function across several trophic levels and at a range of spatial and temporal scales.
