Introduction
I am a conservation biologist working in Sri Lanka following my Masters in Philosophy at University of Colombo. My current work is mainly focused on the study of taxonomy, biogeography, ecology and conservation of Sri Lankan Odonata and avifauna. I'm also interested in the diversity and distribution of other major terrestrial arthropod groups. Over the past decade, I've been involved in many biodiversity assessments, environmental impact assessments and field research in ecology and conservation biology.

The consequence of forest conversion into human land-use systems on tropical biodiversity is needed to be assessed in order to initiate proper conservation and management strategies. In this study the bird species diversity and composition were characterized along with the vegetation structural components in four land-use types in Northern Flank of...

The majority of Sri Lanka’s endemic and Critically Endangered western purple-faced langurs, Semnopithecus vetulus nestor, inhabit fragmented and densely populated areas. Habitat loss and fragmentation resulting from agriculture and development may have an impact on the purple-faced langur’s social organization and create challenges to their surviva...

The genus Macromia is represented in Sri Lanka by two endemic species. In this paper a third presumed endemic species is described based on a single male specimen collected at Kirikitta, Weliweriya, Western Province in the low country wet zone of the country. Macromia weerakooni sp. nov. differs from its congeners in Sri Lanka by having turquoise b...

Sri Lanka’s location, historic and geologic isolation from the continental landmass, topography and climate act to shape its biogeography and biodiversity, including conferring a remarkably high level of endemism, given its close proximity to the mainland. The island hosts several ‘point endemic1 species and even monotypic endemic genera. However t...

Sri Lanka is considered one of the world's biodiversity hotspots. Although Sri Lanka has a rich diversity of bats, Kerivoula malpasi is the only bat that is endemic to Sri Lanka, where it is represented by only five records. The other known species of Kerivoula in Sri Lanka, Kerivoula picta, is more widely distributed. This study maps the current a...

Macromia flinti Lieftinck, 1977, is an endemic dragonfly in Sri Lanka and one of the rarest known odonates in the country. Originally described based on a single specimen collected in 1970, it had not been reported in the past 50 years and thus was considered a globally Critically Endangered Species (IUCN), possibly even extinct. Here we report the...

According to published data, 131 dragonfly species from 12 families are currently known from Sri Lanka. The proportion of endemics is 51.1%, with as many as 59 species and 8 subspecies endemic to the island. This extraordinary level of endemicity makes the dragonflies of Sri Lanka an exceptionally interesting group for studies in biodiversity, zoog...

Anisogomphus ceylonicus (Hagen in Selys, 1878) is one of the rarest of the Sri Lankan Odonata. It was first discovered from Ramboda over 140 years ago based on a female specimen, which was originally described as Gomphus ceylonicus and later assigned to the genus Heliogomphus by F. C. Fraser.

Questions (4)
Question
I am planning a field research on dragonflies and I need to mark some of the individuals for a mark recapture study. I have heard that an ideal paint or ink marker should be durable, nontoxic, easy to apply, quick drying, lightweight and resistant to peeling. But what are the ink types or brands that has the specific qualities? 
Question
Habitat preference, Habitat occupancy, habitat selection and habitat usage, any definitions?
Question
I'm especially interested on the effects of forest fragmentation and patch size on forest dwelling species such as Platystictidae species.
Question
I once observed a mating attempt between two Libellulid species but I could not find much information about this.
