As many goose populations across the northern Hemisphere continue to rise, the role of hunters to manage these populations is increasingly being considered. We studied recreational goose hunters in Denmark to assess their behavioural and motivational

Environments are rapidly changing due to climate change, land use, intensive agriculture, and the impact of hunting on predator populations. Here, we analyzed longterm data recorded during 1928–2014 on the size of breeding populations of waders at

A decline in the Danish population of red foxes Vulpes vulpes due to an outbreak of canine distemper (CDV) in 2012 gave us the opportunity to test the hypothesis that the reproductive performance of foxes increases when the population density decline

Functional Responses of Human Hunters to Their Prey — Why Harvest Statistics may not Always Reflect Changes in Prey Population Abundance

Harvest records are often assumed to offer an indirect measure of population abundance in huntable species. However, this requires population density changes are reflected in comparable linear changes in harvest rates. We tested this assumption for c

Assessing hunters' ability to identify shot geese: implications for hunting bag accuracy

Autor: Jens Peder Hounisen, Tommy Asferg, Jesper Madsen, Lars Haugaard, Thomas Kjær Christensen

Publikováno v: Christensen, T K, Madsen, J, Asferg, T, Hounisen, J P & Haugaard, L 2017, ' Assessing hunters' ability to identify shot geese: implications for hunting bag accuracy ', European Journal of Wildlife Research, vol. 63, no. 20 . https://doi.org/10.1007/s10344-017-1080-y

Reliable hunting bag statistics are a prerequisite for sustainable harvest management. Recently, Internet-based hunting bag reporting systems have been introduced in some European countries, e.g. Denmark, which may enable faster and more detailed rep

How does harvest size vary with hunting season length?

Autor: Tommy Asferg, Peter Sunde

Publikováno v: Sunde, P & Asferg, T 2014, ' How does harvest size vary with hunting season length? ', Wildlife Biology, vol. 20, no. 3, pp. 1-9 . https://doi.org/10.2981/wlb.00021

Manipulating hunting season length is often used as a population management tool but the effects of these changes on total harvest have rarely been studied. We modelled relative changes in national annual bag size as a function of relative change in

Publikováno v: The Journal of heredity. 106(6)

Melanistic Eurasian red squirrels Sciurus vulgaris are commonly found on the Danish island of Funen. They are thought to represent native Danish squirrel types and are presently under threat from admixture with introduced red squirrels. In response,

Summary Two methods were used to separate free-ranging mink Mustela vison into wild mink and escaped farm mink. Analysis of stable carbon isotopes was performed on teeth and claws of 226 free-ranging mink from two areas in Denmark. A classification b
