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 ...

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 ...

Systematic reduction in seed rain of large‐seeded and endozoochorous species in pastures compared to forests along a tropical elevational gradient

Applied Vegetation Science, Volume 27, Issue 2, April/June 2024.
By analyzing variation in seed rain among old‐growth montane forests and livestock pastures along a 2,000 m elevational gradient in the tropical Andes of southern Ecuador, this study reveals that large seeds and endozoochorous species are less prevalent in seed rain from pastures compared to seed rain from forests at the same elevation.

Recognition of two morpho-types in eastern South American brackens (Pteridium—Dennstaedtiaceae—Polypodiopsida)

, 2014
In this work we propose the recognition of two well defined morpho-types of Pteridium from eastern South America: P. arachnoideum subsp. arachnoideum s. str., wide-spread from north-eastern Brazil southwards to north-eastern Argentina and Uruguay, and P.
