Landscape factors influencing predation on capercaillie nests by two competing mesopredators: pine marten and red fox

open access: yesWildlife Biology, EarlyView.
Predation by pine martens Martes martes and red foxes Vulpes vulpes is an important factor influencing the population dynamics of capercaillie Tetrao urogallus. However, there is a knowledge gap regarding the relative effects of these mesopredators on the reproductive success of capercaillie. To better understand how various landscape factors influence

Review of investigation of variability of nad1 gene intron B/C of mitochondrial genome in Scots pine (Pinus sylvestris L.) [PDF]

open access: yes, 2009
Background and Purpose: Scots pine (Pinus sylvestris L.) is the most extensively distributed pine, covering the whole Eurasian continent. The detection of genetic variability of Scots pine is of greate importance from the evolutionary point of view as ...

Species Mixing Effects on Height–Diameter and Basal Area Increment Models for Scots Pine and Maritime Pine

open access: yesForests, 2019
Models that incorporate known species-mixing effects on tree growth are essential tools to properly design silvicultural guidelines for mixed-species stands.

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 ...

Environmental change impacts on the C- and N-cycle of European forests: a model comparison study [Discussion paper] [PDF]

open access: yes, 2012
Forests are important components of the greenhouse gas balance of Europe. There is considerable uncertainty about how predicted changes to climate and nitrogen deposition will perturb the carbon and nitrogen cycles of European forests and thereby alter ...

CALEDONIAN SCOTS PINE: ORIGINS AND GENETIC STRUCTURE [PDF]

open access: yesNew Phytologist, 1986
SUMMARYMonoterpene and isozyme loci, used as markers to study the genetic structure of Scots pine (Pinus sylvestris L.) native to Scotland, showed that the endemic populations are not genetically impoverished, in spite of severe contraction in range and numbers as a result of both natural and anthropogenic causes.

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 ...

Disruptant Effects of 4-Allylanisole and Verbenone on \u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) Response to Baited Traps and Logs [PDF]

open access: yes, 2018
We assessed the inhibitory effects of the host compound 4-allylanisole (release rates = 1 and 2 mg/d in 1994, and 1 and 10 mg/d in 2001) on the response of the pine shoot beetle, Tomicus piniperda (L.), adults to funnel traps baited with the attractant ...

The effect of seed coat color grading on height of one-year-old container-grown Scots pine seedlings planted on post-fire site

open access: yesIOP Conference Series: Earth and Environment, 2019
The basis for the present research is an alternative hypothesis about the existence of significant differences between morphometric parameters of Scots pine (Pinus sylvestris L.) seedlings of different color-seed races.
