Data from: Quantifying risk of overharvest when implementation is uncertain

Lasse F. Eriksen, Pål F. Moa & Erlend B. Nilsen
1. Sustainable harvest management implies an ability to control harvest rates. This is challenging in systems that have limited control of resources and resource users, which is often the case in small game harvest management. The difference between management strategies and actual harvest bag size (i.e. implementation uncertainty) may be substantial, but few studies have explored this. 2. We investigated how different management strategies and ecosystem variables affected realised harvest of willow ptarmigan (Lagopus lagopus...

Data from: Parasite escape through trophic specialization in a species flock

Adaptive radiation occurs when species diversify rapidly to occupy an array of ecological niches. Since opportunities for parasite infection and transmission may greatly vary among these niches, adaptive radiation is expected to be associated with a turnover of the parasite community. As major agents of natural and sexual selection, parasites may play a central role in host diversification. The study of parasite turnover may thus be of general relevance and could significantly improve our understanding...

Data from: Draining the pool? Carbon storage and fluxes in three alpine plant communities

Mia Vedel Sørensen, Richard Strimbeck, Kristin Odden Nystuen, Rozalia Erzsebet Kapas, Brian J. Enquist & Bente Jessen Graae
Shrub communities have expanded in arctic and alpine tundra during recent decades. Changes in shrub abundance may alter ecosystem carbon (C) sequestration and storage, with potential positive or negative feedback on global C cycling. To assess potential implications of shrub expansion in different alpine plant communities, we compared C fluxes and pools in one Empetrum-dominated heath, one herb- and cryptogam-dominated meadow, and one Salix-shrub community in Central Norway. Over two growing seasons, we measured Gross...

Data from: Genetics redraws pelagic biogeography of Calanus

Marvin Choquet, Maja Hatlebakk, Anusha K.S. Dhanasiri, Ksenia Kosobokova, Irina Smolina, Janne E. Søreide, Camilla Svensen, Webjørn Melle, Sławomir Kwaśniewski, Ketil Eiane, Malin Daase, Vigdis Tverberg, Stig Skreslet, Ann Bucklin & Galice Hoarau
Planktonic copepods of the genus Calanus play a central role in North Atlantic/Arctic marine food webs. Here, using molecular markers, we redrew the distributional ranges of Calanus species inhabiting the North Atlantic and Arctic Oceans and revealed much wider and more broadly overlapping distributions than previously described. The Arctic shelf species, C. glacialis, dominated the zooplankton assemblage of many Norwegian fjords, where only C. finmarchicus has been reported previously. In these fjords, high occurrences of...
