Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]

Glob Chang Biol
We studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.

Genetic inference of orchid colonization of a Costa Rican lava flow

Biotropica, Volume 55, Issue 6, Page 1195-1202, November 2023., 2023
A 1992 lava flow provides an excellent opportunity to study patterns of colonization and growth of plant populations on a naturally disturbed site. Plants with wind‐dispersed seeds, such as orchids, are often among the earliest colonists after habitat disturbance.

Neutral‐based processes overrule niche‐based processes in shaping tropical montane orchid communities across spatial scales

Journal of Ecology, Volume 111, Issue 8, Page 1614-1628, August 2023., 2023
High compositional turnover, even across habitats with the highest degree of human intervention, suggests that both forest‐dwelling and open‐habitat species do not easily disperse across habitats. Species dispersal is the major force of orchid community turnover and might be strongly dependent upon macroevolutionary processes and species life‐history ...

Disturbance‐specific behavioral responses of giant otters exposed to ecotourism and extractive activities

Animal Conservation, Volume 25, Issue 1, Page 15-26, February 2022., 2022
Behavioral responses of animals to human activity can vary by the type and intensity of disturbance. Giant otters foraged more successfully in protected areas, avoided research vessels in mined and fished lakes and showed tolerance to human presence when previously exposed to ecotourism.

Automated conservation assessment of the orchid family with deep learning

Conservation Biology, Volume 35, Issue 3, Page 897-908, June 2021., 2021
Abstract International Union for Conservation of Nature (IUCN) Red List assessments are essential for prioritizing conservation needs but are resource intensive and therefore available only for a fraction of global species richness. Automated conservation assessments based on digitally available geographic occurrence records can be a rapid alternative,

Diversidad de orquídeas en la isla de Hainan en China: distribución y conservación

Collectanea Botanica, 2015
Las Orchidaceae se distribuyen ampliamente en muchos ecosistemas terrestres con excepción de las zonas polares y desérticas, y constituyen una suerte de «buque insignia» de la conservación biológica. Siendo como es la mayor isla tropical de China, Hainan
