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

Wildlife 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 ...

Hadronic charmed meson decays involving tensor mesons [PDF]

Physical Review D, 2003
Charmed meson decays into a pseudoscalar meson P and a tensor meson T are studied. The charm to tensor meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. It is shown that the Cabibbo-allowed decay $D_s^+\to f_2(1270) ^+$ is dominated by the W-annihilation contribution and has the largest branching ratio ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

The post‐fire recovery of soil seed banks along a fire severity gradient in an Australian threatened mesic forest

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change has increased the likelihood of extreme events, increasing the number of days with dangerous fire weather conditions, resulting in fires with increased severity, frequency and extent.

Radiative decays of vector and pseudoscalar nonets

EPJ Web of Conferences, 2012
Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Distillation of scalar exchange by coherent hypernucleus production in antiproton–nucleus collisions

Physics Letters B, 2017
The total and angular differential cross sections of the coherent process p¯+AZ→ΛA(Z−1)+Λ¯ are evaluated at the beam momenta 1.5÷20 GeV/c within the meson exchange model with bound proton and Λ-hyperon wave functions.

Valons in mesons

Physical Review D, 1985
We present a systematic study of the valon distribution functions and valon structure functions for pions and kaons. The implications of our results for low-${p}_{T}$ inclusive reactions are emphasized. The complications with the structure function of strange valons are discussed and suggestions are made for future experiments to extract it from the ...

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Mass Spectrum of Noncharmed and Charmed Meson States in Extended Linear-Sigma Model

Particles
The mass spectrum of different meson particles is generated using an effective Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields and quark flavors, up, down, strange, and charm.
