On the botanical history and nomenclature of the New World genus Piscidia (Fabaceae)

Nordic Journal of Botany, EarlyView.
Piscidia L. (Fabaceae) is a New World genus with nine recognized taxa (seven species and two varieties). The previous nomenclatural revisions, made in 1910 and in 1969, are revisited here. The names Derris grandifolia Heyde & Lux ex Donn.Sm. and P. cubensis Urb. required step II lectotypifications, with an epitype for the latter name.

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

A coral-algal phase shift in Mesoamerica not driven by changes in herbivorous fish abundance

PLoS ONE, 2017
Coral-algal phase shifts in which coral cover declines to low levels and is replaced by algae have often been documented on coral reefs worldwide. This has motivated coral reef management responses that include restriction and regulation of fishing, e.g.

Systemic bio‐inequity links poverty to biodiversity and induces a conservation paradox

People and Nature, EarlyView.
Abstract Biodiversity is declining globally while inequity is growing, and poverty rates are not improving. Global sustainable development and conservation initiatives aim to address biodiversity loss and poverty simultaneously. Through text analysis of global biodiversity policies, we identified a consistent narrative that countries with high ...

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.
