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.

Fruit Traits Reflect Adaptation to Dispersers Along a Tropical Elevational Gradient. [PDF]

Ecol Evol
This study investigates how fruit traits related to frugivore dispersal—specifically diameter, colour and presentation—vary along an elevation gradient in Papua New Guinea. Results showed that fruit diameter decreases with elevation, bird‐attracting colours are more common at higher elevations, and branch‐borne (ramiflorous) fruits increase with ...

A NEW ALKALOID ISOLATED FROM Tabernaemontana hystrix Steud. (Apocynaceae) AND THE ANTIPROLIFERATIVE POTENTIAL OF THE ROOT BARK AGAINST HUMAN CERVICAL CANCER (HeLa) [PDF]

Química Nova
Cervical cancer is the fourth most common cancer in the world and the third most common in Brazilian women. The search for compounds with anticancer potential is important, since cancer is a public health problem, and some drugs may lead to side effects.

Arboreal Duels in a Shared Niche: Direct Observations of Vinesnake (Thelotornis mossambicanus) Predation on Chameleons (Chamaeleo dilepis) Reveal Complex Foraging Dynamics

African Journal of Ecology, Volume 64, Issue 4, June 2026.
ABSTRACT Predator–prey interactions in three‐dimensional arboreal habitats are among the most complex and least observed ecological processes in terrestrial ecosystems. Here we report two predation events of the Eastern Vinesnake (Thelotornis mossambicanus) on the Flap‐necked Chameleon (Chamaeleo dilepis) in sand‐forest habitat of the Zambezi Delta ...
