A guest post by Greg Goldsmith, a tropical plant ecologist and part of the multitalented team behind Canopy in the Clouds. He describes methods he used to track and analyze audience engagement in the educational website with colleagues Drew Fulton, Colin Witherill, and Javier Espeleta in an article out today in Ecosphere.

Read MoreInside the rounded fruit of a fig tree is a maze of flowers. That is, a fig is not actually a fruit; it is an inflorescence—a cluster of many flowers and seeds contained inside a bulbous stem. Because of this unusual arrangement, the seeds—technically the ovaries of the fig—require a specialized pollinator that is adapted to navigate within these confined…
Read MoreResearcher David Hughes has expanded research on a parasitic fungus and its carpenter ant host. As explained in an excerpt from a previous EcoTone post: Scientists have found that the parasitic fungus Ophiocordyceps unilateralis has possibly been invading carpenter ants (Camponotus) for 48 million years. The parasite not only infects the ant, but it manipulates the ant’s behavior, driving it…
Read MoreThere is a world within the canopy of a tropical cloud forest that not many people get to see. In this unique ecosystem—maintained by the exceptionally wet microclimate of cloud cover—orchids, moss, lichens and other epiphytes grow in every crease and pocket of the supporting tree branches. Here, hundreds of species of birds, along with monkeys and other mammals navigate…
The gardeners described here are not concerned with trimmed topiaries or manicured lawns—though, like designers of landscape gardens, these workers are exceptionally picky. And they have to be if they are going to survive. That is, ants such as Myrmelachista schumanni and Camponotus femoratus of South America depend on certain plants for shelter, and in return, they offer these plants…
