Climate change versus deforestation: Implications for tree species distribution in the dry forests of southern Ecuador. [PDF]

PLoS ONE, 2017
Seasonally dry forests in the neotropics are heavily threatened by a combination of human disturbances and climate change; however, the severity of these threats is seldom contrasted.

Constituintes químicos voláteis e não-voláteis de Cochlospermum vitifolium (Willdenow) Sprengel [PDF]

Quimica Nova, 2005
The essential oils from leaves, root bark and root wood of Cochlospermum vitifolium were investigated for the first time. The oils were obtained by hydrodistillation and analyzed by GC/MS. The main volatile constituents were b-caryophyllene (8.2 - 46.5%), b-bisabolene (11.5 - 29.3%), g-muurolene (28.4%), a-humulene (26.0%), 1-hydroxy-3-hexadecanone (16.

Do soil microbes and abrasion by soil particles influence persistence and loss of physical dormancy in seeds of tropical pioneers? [PDF]

Frontiers in Plant Science, 2015
Germination from the soil seed bank (SSB) is an important determinant of species composition in tropical forest gaps, with seed persistence in the SSB allowing trees to recruit even decades after dispersal.

Chronic administration of tetrahydrofuran extracts of Cochlospermum vitifolium (Wild) Sprengel in a mouse diabetes model: Hypoglycemic, antioxidant, and genoprotective effects

Biomedicine and Pharmacotherapy
Diabetes and its complications represent a major global health burden, contributing to rising mortality rates, escalating healthcare costs, and an increasing prevalence worldwide. This has driven renewed interest in traditional medicine as a complementary approach to disease management.

Tiny Patch, Big Value: A Small Dry Forest Patch Supports Wildlife Conservation in Guanacaste, Costa Rica. [PDF]

Ecol Evol
This study highlights the biodiversity value of the Murren Reserve, a small tropical dry forest patch in Guanacaste, Costa Rica. Using camera traps and opportunistic observations, researchers documented 32 wildlife species, including federally endangered species like the ocelot (Leopardus pardalis) and puma (Puma concolor), as well as 73 plant species.

Osmoxylon-like fossils from early Eocene South America: West Gondwana-Malesia connections in Araliaceae. [PDF]

Am J Bot
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.
