Explosive Food and What it Tells Us About Ourselves

Somewhere, there is a hungry elephant, following her nose, wandering an ever-diminishing forest in search of food. She ventures to her usual places, finds them lacking. She wanders further from where she feels safe, considering what she may find closer to the villages nearby.

Somewhere there is a hungry person. Perhaps a farmer, perhaps a hunter. He is looking to drive away pests from his land, or maybe to earn a bit of money from bushmeat. He selects a large fruit or vegetable, say a pumpkin or pineapple. He hollows it out, hides an improvised explosive inside, leaves it where some animal will find it.

We know what happens next. Continue reading

Why We Study The Asian Elephant

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

Hyena girl meets elephant girl – A Chat for Skirts in Science

Some colleagues at the Denver Museum of Nature & Science have started a series featuring conversations by female scientists called Skirts in Science.  The goal is to make women in science more visible to students, especially young women and girls.

I had a lot of fun in this chat with Sarah Benson-Amram, now faculty at the University of Wyoming.  Here is a brief window into our work:

Many thanks to Paula Cushing, Kimberly Evans, and Marta Lindsay for inviting us to be part of this great series.  Check out their channel here.

Part 2 will have a discussion of how we came to do what we do. Stay tuned!

Wildlife-Viewing is Not Thrill-Seeking

Baretail and Batik with their newborns.

We sometimes forget how fortunate we are to be able to watch peaceful, calm, habituated elephants in Udawalawe.  It’s easy to take for granted when they stand there, threshing their grass en masse, as though it were the most natural thing in the world to have a horde of humans gawking at them from a few meters away. This post may seem self-evident to a younger generation of wildlife watchers, who have grown up in a world packed to the breaking point with human beings and who realize that wilderness is an increasingly rare and precious thing.  But it may challenge the thinking of some, particularly those of an older generation, for whom wilderness was a vast and ominous space teeming with dangerous things.  For the latter, seeing wildlife might satisfy the need for a thrill in the same way as watching a frightening movie or visiting an amusement park – especially if that wildlife acts fierce and ferocious, such as charging elephant might do. This view still prevails among more than a handful of people today, who might think that seeing the “tame” elephants of some national parks is not as much fun as getting a much more “wild” experience in more secluded areas where the animals elicit more mutual terror.

If this is you, or someone you know, then read on and share. This post is for you.

How does empathy help elephants?

In the past week a paper on reassurance behavior in elephants by Plotnik et al. in PeerJ has been generating quite a bit of buzz. The study, which you can learn more about from the researchers themselves here, collected a series of observations on a group of captive elephants in Thailand documenting how they reacted when one of their companions was distressed.  It showed that when some individuals were disturbed in some way and expressed their distress, other individuals approached them and interacted in ways (such as touching, vocalizing) that suggested that they might be trying to comfort or console their companion.  Such behavior would indicate that elephants have the capacity for empathy, along with a handful of other species.

The title of this post is meant to work on at least two levels. First, we might wonder at a biological level – what is the function of the curious  behavior elephants sometimes show toward others in distress? Why might it have evolved? Whom does it benefit? Second, we might wonder at a practical level – should the capacities of elephants endow them with additional conservation value? Should it matter on the ground? So today, the first ever World Wildlife Day, I’d like to examine these two sets of questions, which are very distinct. Continue reading

Wild boar

Curious boar.

December 18, 2012

A breathtaking expanse of bushes peppered with trees.   That is my first impression of Uda Walawe National Park as we pass through the entrance gate in the early hours of the morning.  The shrubs grow densely packed on either side of the ochre-colored road, like a vertically challenged forest.  They are interspersed with teak saplings, a reminder of the days when this park was a timber plantation.  Towering banyan trees soar above the surrounding vegetation, peacocks perched in their uppermost branches.  In the distance, I can see the blue mountains and waterfalls of Nuwara Eliya, and above them, a steely sky striated with rain-laden clouds.  A grey mongoose crosses the road ahead of us, stopping briefly to stare at our jeep before disappearing into the wall of greenery.  Flocks of Common Mynas and Spotted Doves spring into the air as we rumble past.

The Magnificence of Mud

It’s October, and the monsoon is in full force.  As we wrote in an earlier post the elephants love mud.  They’re just oversized piggies with big floppy ears.  Here’s a video for your amusement:

Why do they love mud so much?  As anyone who has seen or enjoyed a muddy spa retreat can tell you, it’s good for the skin and helps with thermoregulation.  Because elephants don’t sweat, when it’s hot outside the evaporating mud cools them off.  Rudyard Kipling so mischievously wrote in ‘The Elephant’s Child’:

‘Don’t you think the sun is very hot here?’ [says the Rock Python]

‘It is,’ said the Elephant’s Child, and before he thought what he was doing he schlooped up a schloop of mud from the banks of the great grey-green, greasy Limpopo, and slapped it on his head, where it made a cool schloopy-sloshy mud-cap all trickly behind his ears. Continue reading
