Elephas maximus Linnaeus, 1758 is listed as an Endangered species (Choudhury et al. 2008). The Sri Lankan sub population of Asian Elephant is also listed as a Nationally Endangered species (MOE 2012). In addition to its wild population, Sri Lanka currently maintains a captive population of elephants for various purposes including exhibition, work a...
We assessed the level of stereotypic behaviour of captive elephants in three institutions in Sri Lanka. At each institution four animals were studied using focal animal sampling. The results showed that elephants at the National Zoological Gardens had significantly higher stereotypic behaviour than elephants at the other two institutions. The reaso...
The dugong (Dugong dugon, Muller 1776) is a mammal considered Vulnerable globally and Endangered locally. In Sri Lankan dugongs are found in calm shallow waters of the Northwest, North and east coast viz., from Kalpitiya to Jaffna with sporadic reports from Trincomalee and Batticaloa. It is a one of the least known mammals occurring in the Sri Lank...
In Sri Lanka thirty species of cetaceans have been recorded to date. The canyon at Trincomalee bay is a multiple submarine canyon complex and anecdotal reports suggest that the Trincomalee bay and its adjacent waters are utilised by a number of cetacean species. Though Cetaceans are known to be abundant in the waters off Trincomalee there is a dear...
In the current study we attempt to identify eight baleen whale carcasses that were washed ashore to the Western, Northwestern and Southern coasts of Sri Lanka in 2010, using molecular phylogenetic techniques. Initial physical examination suggested that these carcasses belonged to blue whales (Balaenoptera musculus). Analysis of sequences of the mit...
Aversive Geofencing Devices (AGDs) are designed to emit audible warning signals followed by electric shocks when animals reach virtual fences (VFs) with the intent that animals will learn to turn away at audio warnings and thereby avoid receiving shocks. AGDs are a potentially useful tool for mitigating human-elephant conflict, but a greater unders...
This book provides an overview about the biodiversity of the Ampara district, the drivers that affect the biodiversity and the current trends in the biodiversity in the district.
This book provides an overview about the biodiversity of the Mannar district, the drivers that affect the biodiversity and the current trends in the biodiversity in the district.
Asian elephants are a principal cause of human-wildlife conflict. This results in the death/injury of elephants and humans and large-scale crop and property damage. Most current human-elephant conflict (HEC) mitigation tools lack the flexibility to accommodate the ecological needs of elephants and are ineffective at reducing HEC in the long-term. H...
The painted bat, Kerivoula picta (Pallas, 1767) is considered one of the most aesthetically appealing bats in Sri Lanka with bright orange fur and black wings. However, very little information is available with regard to the ecology of this species in both local and global contexts. Of its roosting habits, Phillips (1980) reports that in Sri Lanka...
Human-monkey conflicts became a serious problem in Sri Lanka due to extensive deforestation during and after the country's 26-year ethnic war that ended in 2009. By 2015, these conflicts had affected most of the country's administrative districts, and the Department of Wildlife Conservation (DWC) was under severe public and political pressure to re...
In 2006, the western purple-faced langur (Semnopithecus vetulus nestor) was listed as among the world's 25 most endangered primates. A field survey conducted the following year indicated that its population was threatened by human activities , especially deforestation. To address this threat, meetings were held with the community leaders of Waga, a...
Dive times of a single Blue Whale observed in Trincomalee Bay, Sri Lanka, in relation to the abiotic parameters of the bay’s waters and its ability to support large densities of krill from May 2011 to July 2011. Thirty five total dives were observed and its mean dive time was 9.6 ± 0.31 min. The observed whale’s feeding dives lasted longer than wha...
My university doesn't allow the New mendeley reference manager word plugin to be installed on the work computer. However, if there was an exe file for the plugin, this could be bypassed. Any ideas/suggestions welcome. Thanks in advance.
I'm looking for these two articles by W.C.O Hill but am unable to find them. I'd be grateful if someone could help me in this regard. Many thanks in advance.

I need a tag to look into the ranging behaviour of magpie robins (35g in weight). Any recommendations on a tag that's cheap but reliable? would be ideal if it is GPS and where I don't need to retrieve the tag but I suspect the cost would be quite high? any suggestions would be very welcome.
Thanks in advance.
I'm trying to analyse cortisol concentrations from faecal matter and would like to know how many days the hormonal residues are present in the samples before they are collected from the wild.
The binary logistic regression model i ran shows (significantly) that high parasite burdens drive towards higher survival rates in hedgehogs being rehabilitated. its similarly confounding when analysing (using BLR) parasite intensity vs anthropogenic injuries. results show high intensity drives towards natural injuries. is there any publications out there that deals with similar results? thanks in advance.
there are 3 Independant variables. weight, age (range 1-3), infection (range 0-3). the dependant variables are case type (1,0) and result (1,0).
