Arctic, Circumpolar: projects/activities

Important progress has been made in recent decades to describe and understand how arctic terrestrial vertebrate interact, especially concerning predator-prey interactions. Indirect interactions between different prey species modulated by shared predators (e.g. Arctic fox) are believed to have important impacts on the structure and/or dynamics of some communities. Yet, our understanding of these types of interactions is still fragmentary. To fill that gap, we will build on ongoing projects exploring related questions in Canada (Marie-Andrée Giroux, Nicolas Lecomte, Joël Bêty) and Greenland (Olivier Gilg, Niels M. Schmidt), while taking advantage of existing networks (ADSN in North America and “Interactions” program in Greenland and Eurasia). The aim of the project is to promote the implementation of several common protocols that will (1) improve each collaborator’s knowledge at the site level and, more importantly, that will (2) be merged across sites and years to improve our understanding of the functioning and the influence of indirect interactions on arctic vertebrate communities in general.

Five types of data have been identified (by the 5 initiators of the project already mentioned above) as being mandatories to answer questions related to this topic. These data sets will be collected using 5 specific protocols described in the following chapters:

1. Monitor predation pressure using artificial nests
2. Monitor real predation pressure on Calidris nests using Tiny Tags
3. Observations of predators and lemmings (3b: fox scats DNA barcoding)
4. Assessing lemming (or “rodent”) relative abundance using different methods
5. Assessing “herbivores” (excl. rodents) relative abundance using “faeces transects”

FUVIRC will serve ecosystem research, human health research and atmospheric chemistry research by providing UV monitoring data and guidance (i.e. calibration of instruments, maintenance of field test sites), research facilities (laboratories and accommodation), instruments and equipment.

The main objective of the facility is to enhance the international scientific co-operation at the seven Finnish research stations and to offer a very attractive and unique place for multidisciplinary environmental and atmospheric research in the most arctic region of the European Union. Factors such as, arctic-subarctic and alpine-subalpine environment, northern populations, arctic winters with snow, changes in the Earth's electromagnetic environment due to external disturbances and exceptionally long series of observations of many ecological and atmospheric variables should interest new users.

To focus on the status of most of the large migratory Rangifer (caribou/reindeer) herds.

OGS conducts scientific activities within the fields of Earth Sciences and Polar Science in the Arctic, primarily but not exclusively, in the sea with the vessel OGS-Explora. Current OGS activities in the Arctic include a) Pergamon, EU COST Action: European network for study and long-term monitoring of permafrost, gas hydrates and release of methane in the Arctic and climate change impacts; b) IBCAO (International Bathymetric Chart of the Arctic Ocean) to develop a digital bathymetric database to the north of 64°. OGS is the Editorial Board and provides multibeam data; c) Research activities in the frame of PNRA (Italian Antarctic and Arctic National Research Programme) through several projects devoted to paleoceanographic study of the thermohaline circulation on the Eirik Drift (Greenland and study of paleoclimate in the Barents Sea using geological and geophysical data from the International Polar Year EGLACOM cruise of OGS Explora. CORIBAR international project (IT, DE, ES, N, DK) will provided in the next 1-2 years new data for the last item, through MEBO drilling on board RV Maria S. Merian.

Temporal trend monitoring of contaminants in atmosphere and biota in Greenland. Modelling the atmospheric transport pathways and deposition of contaminants in the Arctic as well as determination of climate related parameters.

The overall goal of AON is to obtain data that will support scientific investigations of Arctic environmental system change. The observing objectives are to: 1. Maintain science-driven observations of environmental system changes that are already underway; 2. Deploy new, science-driven observing systems and be prepared for detection of future environmental system change; 3. Develop observing data sets that will contribute to (a) the understanding of Arctic environmental system change (via analysis, synthesis and modelling) and its connections to the global system, and (b) improved prediction of future Arctic environmental system change and its connections to the global system. Main gaps: Understanding Change and Responding to Change panels, has formed an AON Design and Implementation (ADI) Task Force. Composed of Arctic and non-Arctic scientists with experience and expertise in scientific observing and observing system operation and design, the goal of the task force is to provide advice to the scientific community and NSF on observing system/network design options that are available for identifying gaps that hinder scientific understanding of Arctic environmental system change. The task force will hold two workshops and address two main objectives: (1) evaluate the current SEARCH science questions and observing priorities, and recommend new priorities in the light of the environmental system changes that have occurred since 2005; and (2) evaluate observing system/network design methods, including pilot projects and small-scale tests. A publicly available report will be released in summer 2010. It is anticipated that the report will be of interest to the broader Arctic science community, the governments of the Arctic countries and other countries, NGOs and numerous stakeholders.

Track and analyze all bear/human conflicts for all circumpolar polar bear range states (countries). As a result of on-going and predicted future habitat loss, polar bears are expected to spend longer periods of time on land where they are susceptible to human disturbance. At the same time, human activity in coastal areas of the Arctic is increasing (e.g. oil and gas exploration, tourism) in conjunction with an increased number of nutritionally stressed bears occurring on land. The increasing trend of both polar bear and human use of coastal areas has the potential to result in increasing polar bear-human interactions. Harvest data indicates that defense of life kills have been increasing (USFWS unpublished data). To date, polar bear attacks have been rare but when they do occur, they evoke strong public reaction, especially for residents of communities within the range of polar bears. For sound management of polar bears to be implemented, and adequate protection afforded to people living, recreating, and working in polar bear country, it is imperative that polar bear managers assemble a database of critical information related to bear-human interactions. Interactions with humans may threaten polar bears by: (1) displacement from preferred habitats, such as denning, feeding and resting areas; (2) ingestion of or exposure to contaminants or toxic substances; (3) association of humans with food (food-conditioning) resulting in nuisance bears being killed due to safety concerns for local residents/workers. Polar bear managers can help maintain the current status of their polar bear populations by reducing lethal take of polar bears during bear-human interactions. To prevent escalating conflicts between polar bears and humans, bear-human interaction plans need to be developed and implemented. During the March 2009 Polar Bear Range States Meeting in Tromso, Norway the U.S. was tasked with taking the lead on developing a polar bear / human interaction initiative to address the anticipated future increase in interactions due to climate change. Tor Punsvik, Environmental Advisor, Office of The Governor of Svalbard, Norway and Dr. Terry D. DeBruyn, Polar Bear Project Leader, FWS, Alaska were requested by the Range States to develop a polar bear/human interaction database for the next Range States Meeting in Canada in 2011. It is anticipated that a draft database, populated with data from both the U.S. and Norway, will be ready by November 2009 for testing and comment by the Polar Bear Specialist Group (PBSG). The draft database will be distributed to PBSG members, comment sought, and a request made that members populate the database with pertinent polar bear/human incidents (of primary interest, initially, are records from each country that relate to the use of bear spray and fatalities (both bear and human) resulting from bear-human interactions). At a subsequent meeting of U.S. and Norway in spring 2010, the database will be updated and thereafter redistributed to the PBSG and Range State members. It is anticipated that data from all Polar Bear Range States will then be available for consolidation and validation in winter 2010 and ready to present at the Range States meeting in 2011. To ensure the success of the project, partnering with various agencies and pertinent groups in the range state countries will occur. The Polar Bear Range States parties agree on the need to develop comprehensive strategies to manage bear-human conflicts. Some existing strategies include active deterrence, reduction of attractants, and community education and outreach. Expertise developed for management of other bear species should be consulted in the development of strategies specific to polar bears. The parties agreed to exchange experiences with management of bear-human interactions. Two specific opportunities were identified to develop bear-human interaction strategies: the upcoming Bear-human Workshop in November 2009 in Canmore, Alberta, Canada and the Polar Bear Aversive Conditioning Workshop planned to be held in Alaska in 2010. The Polar Bear-Human Information Management System (PBHIMS) has been developed to standardize the collection of polar bear data across the Range States. This system provides a user-friendly data entry interface and the ability to analyze the collected data. Data stored in the system includes bear-human conflicts, bear observations, bear harvests, and bear natural history data. Scanned images of the original bear forms, narratives, reports, and photos can be attached to each incident to provide additional information that may not be captured in the system. Main gaps: Developed for use by USFWS; other range states are not using it yet.

The main objective is to monitor and assess the impacts of global change on the Human-Rangifer System across the Arctic through cooperation, both geographically and across disciplines. CARMA is a network of researchers, managers and community people that share information on the status of the world's wild Rangifer (reindeer and caribou) populations and how they are affected by global changes (e.g. climate change and industrial development). CARMA is primarily focussed on the status of most of the large migratory Rangifer herds and thus, as yet, do not deal with woodland caribou and Peary caribou in North America or forest and marine reindeer in Fennoscandia and Russia. As well, the do not deal with domestic reindeer or the herding economy. Network type: - Networking - Data, experience and knowledge exchange

The objective of our work with arctic terrestrial plants and with algae is to study the range of climate adaptation as is expressed in special ultrastructure of cells and tissues, in photosynthetic metabolism, in antioxidative and sun screen compounds under a cold and reduced PAR / UV-B environment (climate different to alpine conditions). This is a comparison of ecophysiological processes already worked out mainly from high alpine plants, which live periodically under stronger cold and under different light regimes, especially higher UV-B and PAR irradiation. We want to find out, whether adaptations found in some alpine organisms occur similarly in polar forms.

The aim of this research program is to examine the response of animal populations to environmental variability at different spatial scales. We attempt to determine how individuals respond to the spatial heterogeneity of their environment, and what are the consequences of this response for the dynamics of subdivided populations. Specifically, we consider an ecological system involving biotic interactions at three levels: seabirds, their tick _Ixodes uriae_, and the microparasite _Borrelia burgdorferi_ sensu lato (Lyme disease agent). Colonies of seabirds represent discrete entities, within and among which parasites can circulate. Our previous work on this system in the norwegian arctic has enable us to show that (1) host dispersal can be affected by local conditions, (2) seabird tick populations are specialised among different host species, namely between sympatric kittiwakes _Rissa tridactyla_ and puffins _Fratercula arctica_, (3) in the kittiwake, females transmit antibodies against _Borrelia burgdorferi_ when their chicks have a high probability to be exposed to the tick vector. We propose to combine different approaches, incorporating field surveys and experiments and population genetic studies (of hosts and parasites), in order to better understand the role of local interactions and dispersal in the dynamics of such a system. The research program implies collaborations with researchers from other french groups, as well as with Canadian (Queen’s University) and Norwegian colleagues (from NINA and the University of Tromsø).

The 2003 field activity will be mainly dedicated to coring activity which includes: 1. the sampling of snow and ice cores from a Ny-Ålesund nearby glacier (midre Lovenbreen). 2. the collection of near coast (Kongsfjorden) and lakes sediments (maximum under pack depth 30 m). Sampling collection of ice and sediment cores will be performed using a portable, electric operated, sampling corer. The transport of all materials up to each sampling station should be performed with snowcats.

One of the major benefits of performing measurements at Ny-Ålesund is the availability of a monitoring station on Mount Zeppelin, 474m asl. Given the typical height of the Arctic inversion layer during the envisaged measurement period, it will be possible to continuously monitor mercury and particulate in the free troposphere at the same time as performing ground level monitoring. The simultaneous measurements above and below the boundary layer should provide evidence for the mode of elemental Hg replenishment, whether it is from due to exchange with the free troposphere, or transport occurring at sea level. The proposed collaboration, by collecting data from two strategically placed Arctic stations, in the paths of different air masses and data from above the Arctic inversion layer would provide the most comprehensive set of Arctic mercury measurements performed to date.
