Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

open access: yesWildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Micro‐habitat selection by boreal woodland caribou improves access to food

open access: yesWildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Non-spectator Contributions To The Lifetime of $\Lambda_{b}$

open access: yes, 2003
In this work, we evaluate the contributions of non-spectator effects to the lifetimes of $\Lambda_b$ and B-mesons. Based on the well-established models and within a reasonable range of the concerned parameters, the contributions can reduce the lifetime ...

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

open access: yesWildlife Monographs, EarlyView.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Analysis of the electromagnetic form factors and the radiative decays of the vector heavy-light mesons

open access: yesPhysics Letters B
In this article, we analyze the electromagnetic form factors of the vector heavy-light mesons to the pseudoscalar heavy-light mesons in the framework of three-point QCD sum rules, where the contributions of vacuum condensate terms 〈q‾q〉, 〈q‾gsσGq ...

Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

open access: yesWildlife Monographs, EarlyView.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Study of D^{**} and D^{*'} Production in B and C Jets, with the Delphi Detector [PDF]

open access: yes, 1998
Using D$^{*+}$ mesons exclusively reconstructed in the DELPHI detector at LEP, orbital and radial excitations of non strange charmed mesons are studied. The multiplicities of the two narrow $D^0_1$ and $D^{*0}_2$ orbital excitations are measured in $Z^0 \

B-meson-quark coupling constant and decay width of B*-meson

open access: yesFizika B : a journal of experimental and theoretical physics, 1998
Određuju se konstante vezanja pion – kvark (gπqq) i B-mezon – kvark (gB−qq) u procesima B∗−→B−π0 i B∗−→B−γ. Njihove se širine raspada računaju preko izravnog vezanja π0 i B− s kvarkovima koji miruju u B∗− mezonu.
