Harmonizing circumpolar monitoring of Arctic fox: benefits, opportunities, challenges and recommendations 

Berteaux, Dominique; Thierry, Anne-Mathilde; Alisauskas, Ray; Angerbjörn, Anders; Buchel, Eric; Doronina, Liliya; Ehrich, Dorothee; Eide, Nina Elisabeth; Erlandsson, Rasmus; Flagstad, Øystein; Fuglei, Eva; Gilg, Olivier; Golstman, Mikhail; Henttonen, Heikki; Ims, Rolf Anker; Killengreen, Siw Turid; Kondratyev, Alexander V.; Kruchenkova, Elena; Kruckenberg, Helmut; Kulikova, Olga; Landa, Arild Magne; Lang, Johannes; Menyushina, Irina; Mikhnevich, Julia; Niemimaa, Jukka; Norén, Karin; Ollila, Tuomo; Ovsyanikov, Nikita; Pokrovskaya, Liya; Pokrovsky, Ivan G.; Rodnikova, Anna Y.; Roth, James D.; Sabard, Brigitte; Samelius, Gustaf; Schmidt, Niels-Martin; Sittler, Benoit; Sokolov, Aleksandr A.; Sokolova, Natalya A.; Stickney, Alice; Unnsteinsdóttir, Ester Rut; White, Paula A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
The biodiversity working group of the Arctic Council has developed pan-Arctic biodiversity monitoring plans to improve our ability to detect, understand and report on long-term change in Arctic biodiversity. The Arctic fox (Vulpes lagopus) was identified as a target of future monitoring because of its circumpolar distribution, ecological importance and reliance on Arctic ecosystems. We provide ...

Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome 

Rheubottom, Sarah I.; Barrio, Isabel C.; Kozlov, Mikhail V.; Alatalo, Juha M.; Andersson, Tommi; Asmus, Ashley L.; Baubin, Capucine; Brearley, Francis Q.; Egelkraut, Dagmar; Ehrich, Dorothee; Gauthier, Gilles; Jonsdottir, Ingibjørg; Konieczka, Sophia; Lévesque, Esther; Olofsson, Johan; Prevéy, Janet S.; Slevan-Tremblay, Guillaume; Sokolov, Aleksandr; Sokolova, Natalia; Sokovnina, Svetlana; Speed, James David Mervyn; Suominen, Otso; Zverev, Vitali; Hik, David S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-03)
Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current levels of invertebrate herbivory vary across the Arctic is limited and generally restricted to a single host plant or a small group of species, so predicting future change remains ...

Long-distance plant dispersal to North Atlantic islands: colonization routes and founder effect 

Alsos, Inger Greve; Ehrich, Dorothee; Eidesen, Pernille Bronken; Solstad, Heidi Merethe; Westergaard, Kristine Bakke; Schonswetter, Peter; Tribsch, Andreas; Birkeland, Siri; Elven, Reidar; Brochmann, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-15)
Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic founder effect on five islands is associated with dispersal distance, island size and species traits. Most species colonized postglacially via multiple dispersal events from several ...

Vicariance, dispersal, and hybridization in a naturally fragmented system: the afro-alpine endemics Carex monostachya and C. runssoroensis (Cyperaceae) 

Gizaw, Abel; Kifilemichael, Tigist Wondimu; Tusiime, Felly Mugizi; Masao, Catherine; Abdi, Ahmed Abdikhadir; Popp, Magnus; Ehrich, Dorothee; Nemomissa, Sileshi; Brochmann, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-08)
The naturally fragmented habitat on the tallest African mountains provides a good model system to study vicariance, dispersal, and hybridization. Many mountains are separated by lowland that likely was unsuitable for high-alpine plants even during cold climatic periods. <br> We explore the relative importance of these processes using two endemic sister species: the widespread Ethiopian/eastern East ...

Vole abundance and reindeer carcasses determine breeding activity of Arctic foxes in low Arctic Yamal, Russia 

Ehrich, Dorothee; Cerezo, Maite; Rodnikova, Anna Y.; Sokolova, Natalya A.; Fuglei, Eva; Shtro, Victor; Sokolov, Aleksandr A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-16)
High latitude ecosystems are at present changing rapidly under the influence of climate warming, and specialized Arctic species at the southern margin of the Arctic may be particularly affected. The Arctic fox (Vulpes lagopus), a small mammalian predator endemic to northern tundra areas, is able to exploit different resources in the context of varying tundra ecosystems. Although generally widespread, ...

Homage to Hersteinsson and Macdonald: climate warming and resource subsidies cause red fox range expansion and Arctic fox decline 

Elmhagen, Bodil; Berteaux, Dominique; Burgess, Robert. M.; Ehrich, Dorothee; Gallant, Daniel; Henttonen, Heikki; Ims, Rolf Anker; Killengreen, Siw Turid; Niemimaa, Jukka; Norén, Karin; Ollila, Tuomo; Rodnikova, Anna Y.; Sokolov, Aleksandr A.; Sokolova, Natasha A.; Stickney, Alice A.; Angerbjörn, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
Climate change can have a marked effect on the distribution and abundance of some species, as well as their interspecific interactions. In 1992, before ecological effects of anthropogenic climate change had developed into a topical research field, Hersteinsson and Macdonald published a seminal paper hypothesizing that the northern distribution limit of the red fox (Vulpes vulpes) is determined ...

Snowmobile impact on diurnal behaviour in the Arctic fox 

Fuglei, Eva; Ehrich, Dorothee; Killengreen, Siw Turid; Rodnikova, Anna Y.; Sokolov, Aleksandr A.; Pedersen, Åshild Ønvik (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-16)
As tourism increases globally, studies have documented impacts on wildlife from anthropogenic disturbances. In this observational experiment we aimed to investigate if snowmobile traffic affected the diurnal activity of Arctic fox in High Arctic Svalbard. We conducted the study in two areas in Svalbard, one control area with low snowmobile traffic and one experimental area with high snowmobile ...

Genetic roadmap of the Arctic: plant dispersal highways, traffic barriers and capitals of diversity 

Eidesen, Pernille Bronken; Ehrich, Dorothee; Bakkestuen, Vegar; Alsos, Inger Greve; Gilg, Oliver; Taberlet, Pierre; Brochmann, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-07-22)
<ul> <p><li>We provide the first comparative multispecies analysis of spatial genetic structure and diversity in the circumpolar Arctic using a common strategy for sampling and genetic analyses. We aimed to identify and explain potential general patterns of genetic discontinuity/connectivity and diversity, and to compare our findings with previously published hypotheses.</li></p> <p> <li>We ...

Geographical area and life history traits influence diet in an Arctic marine predator 

Tartu, Sabrina; Bourgeon, Sophie; Aars, Jon; Andersen, Magnus; Ehrich, Dorothee; Thiemann, Gregory W.; Welker, Jeffrey Martin; Routti, Heli (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-19)
Global changes are thought to affect most Arctic species, yet some populations are more at risk. Today, the Barents Sea ecoregion is suffering the strongest sea ice retreat ever measured; and these changes are suspected to modify food access and thus diet of several species. Biochemical diet tracers enable investigation of diet in species such as polar bears (Ursus maritimus). We examined ...
