D-mesons in dense nuclear matter

open access: yes, 2005
The D-meson properties in dense nuclear matter are studied. The D-meson spectral density is obtained within the framework of a coupled-channel self-consistent calculation assuming, as bare meson-baryon interaction, a separable potential.

What controls forest litter decomposition? A coordinated distributed teabag experiment across ten mountains

open access: yesEcography, EarlyView.
Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

Lagrangian with off-shell vertices and field redefinitions

open access: yes, 1997
Meson exchange diagrams following from a lagrangian with off-shell meson-nucleon couplings are compared with those generated from conventional dynamics.

Freshwater fishes of the Waterberg aquatic ecoregion, South Africa: Diversity, taxonomic conflicts and conservation concerns

open access: yesJournal of Fish Biology, EarlyView.
Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

The promise of digital herbarium specimens in large‐scale phenology research

open access: yesNew 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 ...

Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

open access: yesNew Phytologist, EarlyView.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

open access: yesNew Phytologist, EarlyView.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Multisite Field Evaluation of Oil Accumulation and Agronomic Performance in Grain and Sweet Sorghums Engineered for Lipid Hyperaccumulation

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Oil sorghum (OS) has been developed by engineering grain (TX430) and sweet (Ramada) genetic backgrounds to accumulate triacylglycerols (TAG) in vegetative tissues as an energy‐dense feedstock for sustainable aviation fuel (SAF) and other biofuels. This study evaluated two TX430 OS lines (TxHO‐2, TxHO‐3) and two Ramada OS lines (RmHO‐1, RmHO‐2)

Multivariate trait profiling and genetic diversity in a global foxtail millet germplasm panel

open access: yesPlant Biology, EarlyView.
Four elite foxtail millet groups discovered from 260 accessions: perfect for breeding climate‐resilient, high‐yielding dual‐purpose crops. Abstract Foxtail millet (Setaria italica L.), known for its climate resilience and dual‐purpose utility, is underutilized in breeding programs despite its agricultural potential.
