Dual‐Locus Metabarcoding Reveals Dry‐Season Dietary Differentiation Between Elephants and Impalas in a South African Savanna

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
We applied dual‐locus DNA metabarcoding to compare dry‐season diets of African elephants and impalas in a South African savanna. Despite similar dietary diversity, the two species differed substantially in dietary composition, with differentiation associated with fine‐scale taxonomic differences rather than overall dietary breadth.

Herbicide impacts on exotic grasses and a population of the critically endangered herb "Calystegia affinis" (Convolvulaceae) on Lord Howe Island [PDF]

open access: yes, 2013
Introduced perennial grasses are capable of altering the habitat of native species, causing reductions in population size and vigour, and potentially affecting life-history processes such as survival, pollination and seedling recruitment. We examined the

PaleoceneIpomoea(Convolvulaceae) from India with implications for an East Gondwana origin of Convolvulaceae

open access: yes, 2018
SignificanceThe origin of the worldwide-distributed morning glory family (Convolvulaceae) has been a matter of debate. The fossil record from late Eocene sediments of North America argues for a Laurasian origin that is in contrast to a molecular ...

Dodder seedlings benefit from apoplastic nutrition by inducing SWEET15‐mediated unloading of sucrose from the host's phloem

open access: yesNew Phytologist, Volume 252, Issue 2, Page 829-842, October 2026.
Cuscuta reflexa infection sites. Summary Cuscuta species are holoparasitic plants that penetrate host stems with haustoria, connect to the vasculature and exhaust water, nutrients and carbohydrates. Parasite seedlings possess only limited maternal reserves and the development of a vascular connection takes several days.

Spatiotemporal Dynamics and Climate Change Impacts on Massive Invasive Plants in Henan Province, China

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
Our findings offer a scientific foundation for the identification, monitoring, and management of malignant invasive alien plants in Henan Province. Given the projected spread of these species, it is crucial to enhance early warning systems and implement targeted regional prevention strategies to minimize their adverse impacts on the environment and ...

Physicochemical Properties, Microstructure, and Sensory Analysis of Compression‐Molded Snacks Based on Modified Starch Produced by Heat‐Moisture Treatment

open access: yesStarch - Stärke, Volume 78, Issue 9, September 2026.
Sweep potato starch was modified by heat‐moisture treatment to produce snacks. Snacks were produced by compression‐molding using pressure between 1–5 tons. Modified starch reduced crystallinity and enhanced texture, yielding stable products. Sensory attributes of snacks were positively correlated with the starch modification. ABSTRACT The transition to

Large‐scale nuclear and plastid phylogenomic analyses inform an updated Angiosperm Phylogeny Group classification: APG V

open access: yesJournal of Systematics and Evolution, Volume 64, Issue 5, Page 845-874, September 2026.
This revision of the APG classification considers the extensive recent analyses of hundreds of nuclear and plastid genes for many angiosperm species. Although previous versions of the APG classification were largely based on uniparentally inherited markers (plastid DNA, largely maternally inherited), there has emerged since APG IV extensive evidence of
