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.

Indicators of soil quality: a South-South development of a methdological guide for linking local and technical knowledge [PDF]

, 2014
The increasing attention paid to local soil knowledge results from a greater recognition that farmer knowledge can offer many insights into the sustainable management of tropical soils and that the integration of local and technical knowledge systems ...

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 ...

Population Study of the Golden Chicken Fern (Cibotium Barometz (L.) J. Sm. in Riau Province, Sumatra [PDF]

, 2017
Cibotium barometz (L.) J.Sm. (Cibotiaceae) is an important export commodity for both traditional and mod-ern medicine. Populations of this species in several countries have decreased rapidly due to the uncontrolled collection of the rhizome parts for ...

Habitat differences in seed‐dispersing vertebrates indicate dispersal limitation in tropical bracken‐dominated deforested areas

Biotropica, Volume 56, Issue 3, May 2024.
Forest regeneration in tropical bracken‐dominated deforested areas is mainly hindered by dispersal limitation. We found differences in species composition of seed‐dispersing birds and bats between the forest and bracken‐dominated areas, which could be one of the main causes of dispersal limitation in forest regeneration in tropical bracken‐dominated ...
