🦧 Primates
Tropical forests are the evolutionary cradle and current stronghold of the order Primates. Of approximately 500 described primate species, over 60% are found exclusively in tropical forest habitats — and the majority of these are threatened by deforestation, hunting, or both. The Amazon basin alone supports more primate species than any other region on Earth, including over 100 species of monkeys that occupy different vertical layers of the forest, exploit different food resources, and maintain fundamentally different social structures. Understanding tropical forest primate ecology illuminates not only the biology of our closest relatives but the functioning of the forest ecosystem as a whole.

Primates are not simply inhabitants of tropical forests — they are active engineers of forest composition and structure. Many primate species are frugivores — fruit eaters — who consume large quantities of fruit and disperse the seeds in their faeces across the forest. Some of the largest tree species in tropical forests are dispersed almost exclusively by large-bodied primates: the seeds are too big for birds or small mammals to transport. When primates are hunted out — as has happened across large areas of the Amazon and Congo Basin — these trees fail to regenerate, gradually altering the forest's species composition. The loss of primates from a forest is not just a conservation tragedy — it is a functional impairment of the ecosystem.
Across the Congo Basin and parts of the Amazon, primates face a threat that operates independently of habitat loss: hunting for bushmeat. In the Congo Basin — home to gorillas, chimpanzees, bonobos, and dozens of monkey species — bushmeat hunting is a multi-billion dollar industry that supplies both subsistence hunters and urban markets. The combination of commercial hunting pressure and habitat loss is driving primate populations to collapse across large areas of Central Africa. Critically Endangered species including the western lowland gorilla and the bonobo face hunting pressure that, combined with their very low reproductive rates — female great apes produce only one offspring every 4-6 years — makes recovery from population declines extremely slow.

Dr. Cruz has spent 16 years studying the extraordinary biodiversity of Neotropical and Southeast Asian rainforests — from jaguar predation behaviour to orchid pollination ecology. Her research examines how tropical species interact, how ecosystems function, and what biodiversity loss means for forest resilience. She draws on data from IUCN, WWF, and Conservation International.
