Deciphering elephant corridor reports

If you are interested in conservation, you have heard the term “corridor”. There are several ways to define corridors. The simplest is to consider that a corridor is an elongated habitat linking two wildlife reserves. Corridors are important because, in our world dominated by humans, protected areas are becoming increasingly isolated from each other. Wildlife […]

Global plant diversity

Our latest paper (here) in the prestigious journal Nature Communications is about global patterns of plant diversity. Species richness is usually described with alpha diversity (number of species in a plot), beta diversity (change of species among plots) and gamma diversity (regional to continental number of species). This paper is about alpha diversity. The number […]

A tribute to Bellan, Forest Watcher

  Nassim Taleb, one of my favorite authors, wrote about heroes in his book “The Black Swan”. He said something a bit startling: if an administrator had taken the proper safety steps, the destruction of the Twin Towers in New York may not have happened. This administrator would have been a hero but no one […]

Incidents with elephants and deforestation

  Contrary to what is advertised, nature lovers might be a bit lost in Coorg. We just published this paper “Deforestation Increases Frequency of Incidents With Elephants (Elephas maximus)” available here, in Tropical Conservation Science. It may be the first paper that shows a correlation between the intensity of deforestation and increased incidents with elephants. […]

Global warming will destroy elephants

Following the 2017 drought, when many elephants died in Tamil Nadu and Karnataka, there was attempts to reassure the public regarding this particular situation (https://www.downtoearth.org.in/news/wildlife-and-biodiversity/elephants-in-drought-hit-karnataka-tamil-nadu-die-to-hunger-thirst-57661). We posted a blog in this website to warn that if elephant populations were regulated by natural conditions centuries ago, today “unnatural” conditions imposed by humanity, prevail. Indeed, we have […]

Trees comparative ecology

Plant conservation is driven by local protection and science. We have published a paper in the New Phytologist (soon to be available), on the organization of plant conduits (called xylem). Understanding the anatomy and physiology of plants has plenty of uses, including predicting reaction to global warming and species success in ecological restoration. Astonishingly, the […]

Rarity of forest trees

We have recently published a scientific paper (here) on rare tree species in the Western Ghats of India with colleagues belonging to different institutions. In general, rarity is of interest to conservation biologists because rare species tend to be at greater risk of extinction than common species. The Western Ghats rain forests have a high […]

If you think India has a population of 2000 tigers, you are mistaken

I follow Conservation Bytes (https://conservationbytes.com), a blog maintained by Dr. Corey Bradshaw, an Australian scientist. He specializes in mathematical modeling of ecological processes, in particular, that of population genetics. In a recent post (https://conservationbytes.com/2018/04/03/why-populations-cant-be-saved-by-a-single-breeding-pair/ and https://theconversation.com/au), he warns that animal (or plant) populations should not become too low, otherwise the species will be lost, even […]

Forests of the world

We recently participated in a scientific article published in the prestigious journal “Proceedings of the National Academy of Science of the USA” (www.pnas.org/cgi/doi/10.1073/pnas.1714977115). The paper entitled ‘a phylogenetic classification of the world’s tropical forests’ was about the classification or relatedness of trees in the tropical forests of the world. For most of us, a forest […]
