Effects of habitat and land use on breeding season density of male Asian Houbara Chlamydotis macqueenii [PDF]

, 2016
Landscape-scale habitat and land-use influences on Asian Houbara Chlamydotis macqueenii (IUCN Vulnerable) remain unstudied, while estimating numbers of this cryptic, low-density, over-hunted species is challenging.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

People and Nature, EarlyView.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Evaluating vital rate contributions to greater sage‐grouse population dynamics to inform conservation

Ecosphere, 2016
Species conservation efforts often use short‐term studies that fail to identify the vital rates that contribute most to population growth. Although the greater sage‐grouse (Centrocercus urophasianus; sage‐grouse) is a candidate for protection under the U.

Views from the hill: Deer stalkers' perspectives on land‐use change in the Scottish Highlands

People and Nature, EarlyView.
Abstract Land‐use and wildlife management are changing globally as part of efforts to address contemporary environmental challenges. In the Scottish Highlands, the hunting—or ‘stalking’—of deer has entered a period of considerable flux primarily because of national policy changes to mitigate climate change and biodiversity loss.

Ecology of greater sage-grouse populations inhabiting the northwestern Wyoming Basin

Human-Wildlife Interactions, 2017
Range-wide population declines of greater sage-grouse (Centrocercus urophasianus; sage-grouse) have been largely attributed to habitat loss and fragmentation. However, the specific conservation threats affecting the ecology of sage-grouse populations may

Star-galaxy separation strategies for WISE-2MASS all-sky infrared galaxy catalogs

, 2015
We combine photometric information of the WISE and 2MASS all-sky infrared databases, and demonstrate how to produce clean and complete galaxy catalogs for future analyses.

Benefit or ecological trap? Monitoring the effects of small clear‐cuts on capercaillie Tetrao urogallus and its mammalian predators

Wildlife Biology, EarlyView.
The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

The importance of simulation assumptions when evaluating detectability in population models

Ecosphere, 2019
Population monitoring is important for investigating a variety of ecological questions, and N‐mixture models are increasingly used to model population size (N) and trends (λ) while estimating detectability (p) from repeated counts within primary periods (

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

Wildlife 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 ...
