Diet composition of the Red‐billed curassow (Crax blumenbachii) and its role as seed disperser in the Atlantic Forest: conservation insights

Restoration Ecology, EarlyView.
Abstract Introduction Forest fragmentation and defaunation are major drivers of biodiversity loss in the Atlantic Forest of Brazil, where 70–90% of tree species depend on animal‐mediated seed dispersal. Reintroduction of large frugivores, such as cracids, is being used to restore species populations and lost ecological functions.

Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

Journal of Integrative Plant Biology, Volume 68, Issue 5, Page 1399-1420, May 2026.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

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 ...

Sustainable production of bioactive alkaloids in Psychotria L. of southern Brazil: propagation and elicitation strategies

Acta Botânica Brasílica
Psychotria is the largest genus in Rubiaceae. South American species of the genus are promising sources of natural products, mostly due to bioactive monoterpene indole alkaloids they accumulate.
