Economic Impact of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) production in the Czech Republic

open access: yesJournal of Forest Science, 2014
The article addresses the issues of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) production in the Czech Republic (CR). Our analysis shows that the tree species can occupy 149,616-163,713 ha in the CR (with respect to ecological limits set by the ...

Effect of site and provenance on the length of transfusion parenchyma of Douglas-fir needles [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2019
Douglas-fir has been the most common introduced conifer species in European plantations since 1825. The analysis of the characteristics of the introduced tree species by conducting genetic tests may predict the success of transfer of Douglas-fir

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

open access: yesWildlife 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.

Pseudotsuga menziesii (Mirb.) Franco as a promising tree species for forest plantations in the western region of Ukraine

open access: yesНаукові праці Лісівничої академії наук України, 2020
Douglas-fir is an introduced species with a pronounced specific character of growth - it grows relatively slowly at a young age, but with a subsequent acceleration of the growth rate and maintaining its high intensity for a long period of time - one ...

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

open access: yesWildlife 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

Combining non‐invasive survey methods increases cumulative detection probability for breeding harlequin ducks Histrionicus histrionicus

open access: yesWildlife Biology, EarlyView.
The effective implementation of new technologies for wildlife population monitoring is limited by knowledge of factors that impact their efficacy. Population monitoring of harlequin ducks Histrionicus histrionicus on their breeding streams in Montana and Idaho in the Northern Rocky Mountains, has historically relied on ground‐based foot surveys (GBS ...

Uncovering temporal patterns of wildlife activity, habitat use and habitat preference from camera‐trap data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract An understanding of habitat use and levels of active behaviour is foundational to wildlife behaviour, ecology, conservation and management. These variables are commonly measured by tracking individuals in space and time using biologging. In principle, camera‐trap data also contain information about both activity level and habitat use; however,

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

open access: yesAnimal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...
