Non‐native invasive plants in tropical dry forests: a global review of presence, impacts, and management

Restoration Ecology, Volume 33, Issue 1, January 2025.
Tropical dry forests (TDF) are among the most‐threatened terrestrial ecosystems, experiencing ongoing conversion to agricultural fields, pasture, and human settlements. Human disturbances are often precursors to invasion of ecosystems by non‐native species, but research on invasion patterns in tropical ecosystems is sparse, and there is no ...

Conservation status of three rare endemic Phaseolus bean (Leguminosae, Phaseoleae) species of Costa Rica

Nordic Journal of Botany, Volume 2024, Issue 12, December 2024.
We aimed at an inventory of all populations of wild Phaseolus (bean) species in Costa Rica, in relation to future plant breeding. During the field work in 2003–2018, three new and rare bean species (i.e. P. albicarminus, P. angucianae and P. hygrophilus) were found in different montane forest habitats which originally occupy a small acreage.

Bird perches and artificial bat roosts increase seed rain and seedling establishment in tropical bracken‐dominated deforested areas

Restoration Ecology, Volume 32, Issue 7, September 2024.
Tropical forests are being reduced by human activities. The use of fire for agricultural expansion generates areas dominated by the bracken fern Pteridium, where forest regeneration is slow. This may be caused by seed limitation, especially of animal‐dispersed seeds, due to the absence of seed dispersers from the forest in deforested areas, calling for

Systematic review and best practices for drone remote sensing of invasive plants

Methods in Ecology and Evolution, Volume 15, Issue 6, Page 998-1015, June 2024.
Abstract Drones have emerged as a cost‐effective solution to detect and map plant invasions, offering researchers and land managers flexibility in flight design, sensors and data collection schedules. A systematic review of trends in drone‐based image collection, data processing and analytical approaches is needed to advance the science of invasive ...
