Environmental changes in biodiversity hotspot ecosystems of
South Ecuador: RESPonse and feedback effECTs (FOR2730)

Abstract:

Plant communities in tropical mountains host a high diversity of species’ morphological traits. Many tropical plant species exhibit a wide range of colored fleshy fruits mainly dispersed by animals. Fruits display a variety of shapes including, for instance, capsules with arillate seeds, drupes with fibrous pulp, and juicy berries. These fruits can enclose just one or many tiny seeds which are dispersed by animals. In the tropical mountains of the southeast of Ecuador, seed size can vary from less than 1 mm (e.g., Miconia sp.) to large seeds with a size of almost 10 cm. Despite the high diversity of fleshy-fruited species and the relevance in plant regeneration, there is very little information that facilitates the identification of even the most common fruits and seeds in tropical mountains. The pronounced endemism in the Andes and the constant description of new plant species increase the necessity to foster local publications including these unique species. This project aims to produce an identification guide as a scientific tool to ease the taxonomic determination of seeds dispersed by animals and to speed up the identification process in the mountain forests of the southeast of Ecuador. This field guide will be a source of consultation for future research units at the San Francisco Scientific Station, and will also contribute to public outreach.
