During the 2017 drought in Tamil Nadu, up to 25 elephants per day were coming to drink water in our water tank.
We were trained as plant ecologists but have made the decision of venturing into research on the Asian elephant. The reasons are two-fold: first, we have a lot of respect and affection for this animal, second is our concern about the demonization of the elephant by the media where it is held responsible for intentionally causing ‘conflicts’ that harm human interests and cause loss of human lives (1). Although the destruction of its habitat, increasing human density and expansion into forest areas are routinely mentioned in most publications, interventions to arrest the loss of habitat and population connectivity is rarely considered a mitigation issue. The human-elephant ‘conflict’ (HEC) mitigation however is given a high priority for funding agencies and research (2,3), although its not clear how successful these efforts have been. Our ultimate reason to get involved in conservation biology however is somehow self-centered. If people don’t learn now to live in harmony with nature, including elephants, then our civilization will alter the biosphere to such an extent that humanity itself will suffer. To us, this is an unacceptable but possible outcome that we attempt to fight. Continue reading →

There are a great many reasons to study elephants; they’re endangered, highly social, quite frankly huge and hold a unique and central place in many cultures. They can also be very strong, sometimes dangerous and slow to do what you want. But that’s not enough to stop me from working on them! One of my interests is actually their life cycles. In the past I’ve studied humans and non-human primates and the fact that elephants evolved long lives, almost on a par with our own, but on a separate evolutionary trajectory was fascinating to me. Elephants also usually only have one calf at a time and each calf is dependent on its mother for many years. These characteristics allow us to test a lot of ideas underpinning theories of life history and ageing, including ones that have been primarily designed with humans in mind.

Bull Asian elephants come in two forms: tusk, and tuskless (this is termed dimorphism). It’s long been thought that tusks must confer an advantage in competitions between males for dominance and mating rights. However a recent study by Karpagam Chelliah and Raman Sukumar of elephants at Kaziranga National Park, India, puts a wrinkle on this common story. Continue reading →
