Visibility bias for sage‐grouse lek counts

open access: yesWildlife Society Bulletin, 2017
Declining populations of greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse) necessitate accurate estimates of population trends. The most widespread approach to monitoring sage‐grouse populations involves counting males attending ...

Greater sage‐grouse male lek counts relative to a wind energy development

open access: yesWildlife Society Bulletin, 2017
Wind energy development is an emerging source of anthropogenic disturbance that could affect greater sage‐grouse (Centrocercus urophasianus; sage‐grouse) populations.

Improving population size estimation at western capercaillie leks: lek counts versus genetic methods

open access: yesJournal of Avian Biology
The western capercaillie Tetrao urogallus, hereafter capercaillie, is the largest galliform bird present in the boreal and montane forests of the Western Palearctic.

Using an individual-based model to assess common biases in lek-based count data to estimate population trajectories of lesser prairie-chickens.

open access: yesPLoS ONE, 2019
Researchers and managers are often interested in monitoring the underlying state of a population (e.g., abundance), yet error in the observation process might mask underlying changes due to imperfect detection and availability for sampling.

Trends in greater sage‐grouse lek counts relative to existing wind energy development in Wyoming

open access: yesWildlife Society Bulletin
Rapid increases in wind energy development globally highlight the need to evaluate how electricity generation may impact wildlife. The greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse) has experienced range‐wide population declines,

Combined effects of energy development and disease on greater sage-grouse. [PDF]

open access: yesPLoS ONE, 2013
Species of conservation concern are increasingly threatened by multiple, anthropogenic stressors which are outside their evolutionary experience. Greater sage-grouse are highly susceptible to the impacts of two such stressors: oil and gas (energy ...

Spatial heterogeneity in response of male greater sage-grouse lek attendance to energy development. [PDF]

open access: yesPLoS ONE, 2014
Landscape modification due to rapidly expanding energy development, in particular oil and gas, in the westernUSA, have prompted concerns over how such developments may impact wildlife.

Estimating capercaillie Tetrao urogallus population size in Scotland from annual leks and counts of broods over the period 2010–2020

open access: yesWildlife Biology, 2023
The population size of capercaille Tetrao urogallus in Scotland was estimated from annual counts of males at 151 known spring lek sites and 45 counts of males, females and their broods in August during the period 2010–2020, combined with published survival estimates.

Comparison of in‐person and remote camera lek surveys for prairie grouse (Tympanuchus spp.)

open access: yesWildlife Society Bulletin, 2023
In‐person lek count surveys are commonly used for estimating population size and trends for prairie grouse. However, the emergence of noninvasive camera trap survey methods holds promise for more cost‐effective and precise estimates of lekking species ...

Local and population-level responses of Greater sage-grouse to oil and gas development and climatic variation in Wyoming [PDF]

open access: yesPeerJ, 2018
Background Spatial scale is important when studying ecological processes. The Greater sage-grouse (Centrocercus urophasianus) is a large sexually dimorphic tetraonid that is endemic to the sagebrush biome of western North America.
