From the Caribbean island of Puerto Rico, scientists have described two new species of Pisonia trees — a group of notorious “birdcatcher trees” known to produce sticky seeds that can entangle (and sometimes even kill) birds.The two newly described trees have been named Pisonia horneae and Pisonia roqueae after Frances W. Horne and Ana Roqué de Duprey respectively, two women who spent several decades trying to document plants of Puerto Rico, researchers report in a new study published in PhytoKeys.“Just like the two large trees remained unrecognised by science until now, the enormous efforts of these two women, who dedicated part of their lives to botanical work, remained largely unrecognised by the community,” Jorge C. Trejo-Torres, researcher at The Institute for Regional Conservation in Florida, U.S., said in a statement.Flowers of Pisonia horneae. Image taken from Caraballo-Ortiz MA, Trejo-Torres JC (2017).Both trees, locally known as corcho, are currently known only from Puerto Rico. So far, the researchers have recorded only isolated individuals or small groups of these trees on ravine banks, cliffs, or rocky areas.“These observations might suggest that either trees tend to colonize these particular habitats due to physiological requirements, or that they represent relicts of a former, more continuous population that was severely fragmented during the intense deforestation period experienced in the island for the past centuries,” the authors write in the paper.Many species of Pisonia are known to disperse their sticky fruits or seeds via birds. However, whether the newly described species use birds to disperse their fruits too, is currently unknown, the researchers say.“So far, we do not know of cases where birds have been trapped by the sticky fruits of the new species, but future studies will explore this possibility,” said the study’s lead author, Marcos A. Caraballo-Ortiz of the Pennsylvania State University.With the formal addition of Pisonia horneae and Pisonia roqueae, Puerto Rico is now home to six species of Pisonia, according to the study.Fully ripe, the infructescences of Pisonia roqueae probably stick to animals as a dispersal strategy.

Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsoredlast_img read more
