Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

open access: yesWildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

The role of forest genetic resources in responding to biotic and abiotic factors in the context of anthropogenic climate change [PDF]

open access: yes, 2015
The current distribution of forest genetic resources on Earth is the result of a combination of natural processes and human actions. Over time, tree populations have become adapted to their habitats including the local ecological disturbances they face ...

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

On the Occurrence of Natural Norway spruce Woodland in the Pieniny Mts (Western Carpathians) [PDF]

open access: yes, 2015
According to Kulczyński (1928), a natural Picea abies forest occurs in the mountain range of the Pieniny Mts on the slopes of the mountain Vysoke skalky.

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

open access: yesWildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Terzyme: a tool for identification and analysis of the plant terpenome. [PDF]

open access: yes, 2018
BACKGROUND: Terpenoid hydrocarbons represent the largest and most ancient group of phytochemicals, such that the entire chemical library of a plant is often referred to as its 'terpenome'.

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

open access: yesWildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Micro‐habitat selection by boreal woodland caribou improves access to food

open access: yesWildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

A catalog of annotated high-confidence SNPs from exome capture and sequencing reveals highly polymorphic genes in Norway spruce (Picea abies)

open access: yesBMC Genomics, 2018
Background Norway spruce [Picea abies (L.) Karst.] is ecologically and economically one of the most important conifer worldwide. Our main goal was to develop a large catalog of annotated high confidence gene SNPs that should sustain the development of ...
