Dietary differentiation of two co‐occurring common bat species (Eptesicus nilssonii and Pipistrellus pygmaeus)

open access: yesWildlife Biology, EarlyView.
Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

Eruli Influence in South Scandinavia – Migration and Remigration

open access: yesMigracijske i etničke teme, 1999
The author treats the question of the influence of the Eruli in the north and their possible original home in south Scandinavia. The remigration of parts of the Erulic people from southern Europe to Thule (Scandinavia) and settlement near the remaining ...

Multi-year prediction of European summer drought conditions for the agricultural sector

open access: yesEnvironmental Research Letters, 2019
Decadal climate prediction, where climate models are initialized with the contemporaneous state of the Earth system and run for a decade into the future, represents a new source of near-term climate information to better inform decisions and policies ...

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

open access: yesWildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

RADON - Radiocarbon dates online 2012. Central European database of 14C dates for the Neolithic and the Early Bronze Age.

open access: yesJournal of Neolithic Archaeology, 2012
In order to understand the dynamics of cultural phenomena, scientific dating in archaeology is an increasingly indispensable tool. Only by dating independently of typology is it possible to understand typological development itself (Müller 2004).

Trade and exchange [PDF]

open access: yes, 2008
If the history of Mediterranean trade during the period c800-1200 is one of decline and reluctant recovery that of Northern Europe is decidedly one of growth. One reason for this is the different points of departure.

Born to die: pack and population level estimates of wolf pup survival and recruitment in the Greater Voyageurs Ecosystem

open access: yesWildlife Biology, EarlyView.
Wolf pup Canis lupus survival is a key driver of wolf population dynamics that remains poorly understood, especially in forested systems, because wolf pups are difficult to monitor. We used a combination of pup counts at dens and remote camera observations to estimate annual survival and recruitment of wolf pups in the Greater Voyageurs Ecosystem, MN ...

South Scandinavian joints and Alpine/Atlantic-ridge tectonics

open access: yesAnnals of Geophysics, 2000
Field observations and studies of the joints and dykes in an area shed light on its younger tectonic development; thus, joint orientations measured in Southern Sweden and in Norway have been statistically studied and compared regarding their tectonic ...

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany

open access: yesWildlife Biology, EarlyView.
Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...
