Assessment of lesser prairie‐chicken translocation through survival and lek surveys

open access: yesWildlife Society Bulletin, 2023
Translocation is a management tool used to restore or augment wildlife populations, but outcomes of translocations are often poorly documented and can have varying levels of success for improving wildlife population declines.

Altering an extended phenotype reduces intraspecific male aggression and can maintain diversity in cichlid fish [PDF]

open access: yes, 2013
Reduced male aggression towards different phenotypes generating negative frequency-dependent intrasexual selection has been suggested as a mechanism to facilitate the invasion and maintenance of novel phenotypes in a population.

Influence of environmental change, harvest exposure, and human disturbance on population trends of greater sage-grouse.

open access: yesPLoS ONE, 2021
Hunter harvest of greater sage-grouse (Centrocercus urophasianus; hereafter "sage-grouse") has been regulated by wildlife agencies during most of the past century.

Effects of density on lek-site selection by Black Grouse Tetrao tetrix in the Alps [PDF]

open access: yes, 2016
Capsule: The Black Grouse is a primarily lekking species, but low population density and lack of suitable habitat can lead to the establishment of non-lekking populations.

Plethysm and lattice point counting [PDF]

open access: yes, 2015
We apply lattice point counting methods to compute the multiplicities in the plethysm of $GL(n)$. Our approach gives insight into the asymptotic growth of the plethysm and makes the problem amenable to computer algebra. We prove an old conjecture of Howe

Mapping oil and gas development potential in the US Intermountain West and estimating impacts to species. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Many studies have quantified the indirect effect of hydrocarbon-based economies on climate change and biodiversity, concluding that a significant proportion of species will be threatened with extinction.

Reversing tree expansion in sagebrush steppe yields population‐level benefit for imperiled grouse

open access: yesEcosphere, 2021
Woody plant expansion into shrub and grasslands is a global and vexing ecological problem. In the Great Basin of North America, the expansion of pinyon–juniper (Pinus spp.–Juniperus spp.) woodlands is threatening the sagebrush (Artemisia spp.) biome. The

Comparison of Conservation Policy Benefits for an Umbrella and Related Sagebrush-Obligate Species

open access: yesHuman-Wildlife Interactions, 2020
Many conservation strategies promote the potential of multiple species benefitting from protection of large areas necessary for the continued viability of 1 species.

Seasonal movements of greater sage‐grouse populations in Utah: Implications for species conservation

open access: yesWildlife Society Bulletin, 2016
Greater sage‐grouse (Centrocercus urophasianus; sage‐grouse) is considered an umbrella species for sagebrush (Artemisia spp.) landscapes in western North America. In 2015, the U.S.

The average number of critical rank-one approximations to a tensor [PDF]

open access: yes, 2014
Motivated by the many potential applications of low-rank multi-way tensor approximations, we set out to count the rank-one tensors that are critical points of the distance function to a general tensor v.
