Molecular Ecology, EarlyView.ABSTRACT Understanding adaptive evolution and survival risks in understory herbs is crucial for the effective conservation of biodiversity. How environmental gradients shape species local adaptation patterns is not well understood, nor is how populations of understory herbs respond to a changing climate.

Information on the structure of the rho meson from the pion form-factor
, 2009 The electromagnetic pion form-factor is calculated in a Bethe-Salpeter approach which accounts for pion rescattering. In the scattering kernel the pion-pion contact interaction from lowest-order chiral perturbation theory is considered together with an ...

Molecular Ecology, EarlyView.ABSTRACT Eusociality in insects has arisen multiple times independently in Hymenoptera (bees, wasps and ants), Blattodea (termites) and Coleoptera (beetles). In Hymenoptera and Blattodea, the evolution of eusociality led to species proliferation. In the hyperdiverse Coleoptera, obligate eusociality evolved only once, in the ancient Australian ambrosia ...

Lagrangian with off-shell vertices and field redefinitions
, 1997 Meson exchange diagrams following from a lagrangian with off-shell meson-nucleon couplings are compared with those generated from conventional dynamics.

The promise of digital herbarium specimens in large‐scale phenology research
New Phytologist, EarlyView.Summary The online mobilization of herbaria has made tens of millions of specimens digitally available, revolutionizing investigations of phenology and plant responses to climate change. We identify two main themes associated with this growing body of research and highlight a selection of recent publications exemplifying: investigating phenology at ...

New Phytologist, EarlyView.Summary The macroevolutionary drivers for disparities in plant species richness across Australia are understudied, hindered by lack of densely sampled comparative phylogenetic data. Here, we address this gap by analysing plant diversification dynamics and quantifying macroevolutionary trajectories of 22 plant clades (4289 species in 14 families) across
