Community dynamics of lignicolous lichens on standing deadwood in a 275‐year chronosequence

Oikos, EarlyView.
Dead trees provide discrete habitat patches in which patch quality changes gradually due to wood decomposition. Although in most cases these patches persist for not more than a few decades, in some ecosystems deadwood decomposition and the consequent change in habitat patch quality can be a centuries‐long process, potentially leading to dynamics of ...

Wave functions and decay constants of $B$ and $D$ mesons in the relativistic potential model

, 2012
With the decay constants of $D$ and $D_s$ mesons measured in experiment recently, we revisit the study of the bound states of quark and antiquark in $B$ and $D$ mesons in the relativistic potential model.

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

Oikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...

In-medium properties of pseudoscalar $$D_s$$ D s and $$B_s$$ B s mesons

European Physical Journal C: Particles and Fields, 2017
We calculate the shift in the masses and decay constants of $$D_s(1968)$$ D s ( 1968 ) and $$B_s(5370)$$ B s ( 5370 ) mesons in hot and dense asymmetric strange hadronic matter using QCD sum rules and chiral SU(3) model.

Quantitative synthesis of the effects of drought on community composition and species interactions in terrestrial ecosystems

Oikos, EarlyView.
Droughts, increasingly frequent under human‐driven climate change, are expected to intensify globally. Both pulsed and prolonged droughts can strongly affect organismal survival and population dynamics, potentially altering terrestrial communities and ecosystems.

Dress for success: climate pressures predict fur insulation and body size in natural and reintroduced populations of a threatened marsupial

Oikos, EarlyView.
Phenotypic variation in functional traits underpins responses to environmental gradients, influencing thermoregulation, energy balance, and long‐term persistence under climate extremes. Climate change is altering these gradients globally, yet in species that have already disappeared from much of their range, adaptive phenotypes may have also been lost,

R D * $$ {R}_{D^{\left(*\right)}} $$ in custodial warped space

Journal of High Energy Physics, 2018
Flavor physics experiments allow to probe the accuracy of the Standard Model (SM) description at low energies, and are sensitive to new heavy gauge bosons that couple to quarks and leptons in a relevant way.

Community perceptions and management of the fleshy‐fruited invasive alien plant Pyracantha angustifolia: Insights from South Africa's Montane grasslands

People and Nature, EarlyView.
Abstract Invasive alien plants can provide economic or cultural benefits to local communities, influencing perceptions and potentially affecting management decisions. Understanding these perceptions is crucial to avoiding inefficiencies, misunderstandings and conflicts in the management of invasive alien species.
