Abundance and occupancy trends of sooty grouse in western Oregon: determining best modeling practices by comparing observed and simulated data

Wildlife Biology, EarlyView.
Sooty grouse Dendragapus fuliginosus are large game birds that occupy montane forests in the Pacific Northwest, USA. These forests have been altered by human activities, which have been shown to have both positive and negative impacts on local populations.

Passive acoustic monitoring with AI‐based detection and identification reveal sooty grouse hooting patterns in western Oregon

Wildlife Biology, EarlyView.
Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

A new data reduction scheme to obtain the mode II fracture properties of Pinus Pinaster wood

, 2006
In this work a numerical study of the End Notched Flexure (ENF) specimen was performed in order to obtain the mode II critical strain energy released rate (GIIc) of a Pinus pinaster wood in the RL crack propagation system.

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

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

Wildlife 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 ...

The effects of moose and pine density on browsing damage in Swedish pine forests

Wildlife Biology, EarlyView.
Moose Alces alces is a culturally and economically important game species in Sweden, but their browsing on regenerating Scots pine trees Pinus sylvestris often causes extensive damage to the production and quality of timber. Forest and wildlife managers are faced with the dilemma of how to reduce damage to timber trees while also supporting moose ...

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

Wildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Quarantine is important in restricting the spread of exotic seed-borne tree pathogens in the southern hemisphere

, 2002
The lack or destruction of indigenous forests in the southern hemisphere has in some cases led to extensive afforestation with exotic softwoods that subsequently developed into large successful forestry industries.
