A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe–Mozambique) and the Significance of Open Habitats

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...

IUCN Red List Regional Assessment of the Flora of Niue Utilising Indigenous Local Knowledge and Botanical Information

Journal of the Royal Society of New Zealand, Volume 56, Issue 2, April 2026.
A regional assessment of the indigenous vascular plants of Niue is presented using the IUCN Red List criteria. The assessment was undertaken during a community workshop that drew on the indigenous local knowledge and scientific information. The assessment comprised 197 named taxa and 8 indeterminate entities, with 4 (2.0%) taxa assessed as Extinct and ...

Isolation of 18 Microsatellite Loci in the Desert Mistletoe Phoradendron californicum (Santalaceae) Via 454 Pyrosequencing

Applications in Plant Sciences, 2013
Premise of the study: Microsatellite primers were developed for the parasitic mistletoe Phoradendron californicum to investigate to what extent population genetic structure depends on host tree distribution within a highly fragmented landscape.

Mowing Modulates the Biotic Filter of Expansive Species

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Management type and expansive species influence plant community diversity in complex ways. Overall increase of expansive species cover acts as biotic filter in reducing the alpha and beta taxonomic and phylogenetical diversity. However, the filtering effect is modulated by management type, being more intense under mown grasslands.

Uncovering biodiversity deficits: Experimental evidence for dispersal limitation of woody species in Mediterranean forest patches

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
We experimentally introduced seeds of woody species into Mediterranean forest patches to test whether species’ absences reflected dispersal limitation or habitat unsuitability. Similar establishment rates showed that unoccupied patches are suitable for establishment but experience limited seed arrival, uncovering diversity deficits that can be restored

Ant‐mediated seed dispersal in the Poaceae: Evidence of myrmecochory in green foxtail (Setaria viridis) and giant foxtail (Setaria faberi)

Plant Species Biology, Volume 41, Issue 1, January 2026.
Model systems have been developed for certain mutualistic interactions, such as pollination, root nodules, and mycorrhizal symbiosis, advancing our understanding of these forms of mutualism. However, in the area of seed dispersal mutualism, a model system has been lacking. Here, we provide evidence of ant‐seed dispersal mutualism in Setaria viridis and

Secondary Metabolite Profiling, In Vitro Antimicrobial Activity Evaluation, and In Vivo Acute Toxicity Assessment of Osyris quadripartita and Toddalia asiatica Leaves and Stem Bark Extracts

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
In Ethiopia, Osyris quadripartita (Santalaceae) and Toddalia asiatica (Rutaceae) are traditionally used to treat malaria, skin and stomach disorders, and other tropical diseases. This study screened the major secondary metabolite profiles and evaluated the in vitro antimicrobial and in vivo acute toxicity effects of chloroform and methanol extracts ...
