Conference Paper
Full-text available
Satellite data play an important role in investigating the relationships between the spatial patterns of vegetation and environmental variables. The aim of this study was to investigate spatial distribution of canopy dieback using remotely sensed data and in conjunction with field collected data in upper montane forest. The study was conducted in t...

This study evaluates the composition and growth of naturally grown tree seedlings in dieback affected forests in Horton Plains National Park. Forty plots (plot size: 1 m2) were established under disturbed (20 plots) and relatively undisturbed forests (20 plots). Seedlings were tagged and root collar diameter and height of tagged seedlings were meas...
Article

Gastrodia gunatillekeorum, a new species in the family Orchidaceae, is described and illustrated from a tropical lowland rainforests of Sri Lanka. It is morphologically close to G. spatulata which is endemic to Indonesia owing to the white flower front with yellowish-orange colour on the inner wall of perianth tube and free part of perianth tube re...
Conference Paper
The blue carbon ecosystems such as tropical mangroves are proven that highly efficient at sequestering carbon dioxide. The mangrove is a globally important carbon sink that has been always linked with biological and physiological processes in organic carbon sedimentation. Among the various biological interactions, the terrestrial crabs (sesarmidae)...
Article
Oberonia mahaeliyensis C. Bandara, Lakkana, Ediriweera sp. nov. is described and illustrated in montane cloud forests of Sri Lanka. Complete taxonomic description, color photographs and line drawings of the species are provided in this account.
Article
Full-text available
We evaluated the composition, structure, and dieback of a montane forest in relation to soils and physiography of an important biogeographic region that has been sparsely studied. Our objectives were to (1) describe the forest composition and structure; (2) assess the current extent of dieback; and (3) relate tree composition, structure, and diebac...
Article
Full-text available
The present study was carried out in the recently established Warathenna-Hakkinda EPA in the Kandy District, Sri Lanka to investigate the avifaunal diversity and conservation threats. Sampling was conducted in two main habitat types: river islands and riverine forests. Both point count (10 m radius) and line transect (200 m long) methods were utili...
Article
Full-text available
The freshwater angelfish, Pterophyllum scalare like many other cichlids show parental care of embryos and larvae. This study was carried out to investigate the embryonic development of P. scalare, which shows biparental care and substrate brooding. During the study adult reproductive behavior and parental care was observed. Once the eggs were ferti...

The Mahaweli River, which is the longest river in Sri Lanka, flows through the wet, intermediate and dry zones of the country. Large extents along this river are yet to be explored for its rich biodiversity. One such area along the Mahaweli River at Gatambe, Warathenna in the Kandy District appears to harbor a diverse community of flora and fauna a...

The golden carp, Cyprinus carpio is a popular ornamental fish as well as a favorite food fish in many countries. The present study focused on documenting the early and later embryonic development of the golden carp as a representative of Family Cyprinidae. Different stages during embryogenesis were observed and photographed under a Zeiss Primo Star...
Conference Paper
Full-text available
Freshwater angelfish are most popular ornamental fish in the world. Even though sufficient information on their reproductive behavior and larval rearing is available, similar to many other species their embryonic development is poorly understood. An understanding of embryogenesis is essential not only for culturing of a species but also to determin...
Conference Paper
Full-text available
Horton Plains National Park (HPNP) is a tropical montane cloud forest in the central highlands of Sri Lanka. Significant tree dieback has been reported in the recent past that is believed to alter the floristic composition and structure of the forest. This study examines the spatial variations in species composition and abundance of the vegetation....

Thermal ecology of Sri Lankan endemic agamid lizard species is poorly known, but vital for their conservation. This study examined the thermal ecology of Otocryptis wiegmanni both under wild and captive conditions. External body temperature (Tb), corresponding environmental temperature (Te), sex and behaviour of 121 lizards were recorded. In captiv...

Sri Lanka has vast diversity and endemicity of both flora and fauna. The Mahaweli River is the longest river and it originates from the central highlands and flows through the wet, intermediate and dry zones of the country. It helps sustain a rich biological diversity however large extents along the river are yet to be explored for its rich biodive...

Materials and methods Results and Discussion  In both wild and captive conditions external body temperature (Tb) was significantly lower than corresponding environmental temperature (Te) (p>0.05) Mean differences (Tb-Te) were,  In Wild-1.59 o C  In Captivity-0.91 o C  Tb of males and females were not significantly different in both conditions (...

Full-text available
Otocryptis wiegmanni is an endemic lizard commonly known as “Sri Lankan Kangaroo Lizard”. Facts related to growth and reproduction are not adequate for this species. Here we summarize the egg laying behavior of six gravid females of O. wiegmanni captured from Lower Hanthana and the initial growth patterns of hatchlings. The observations were done u...

Sri Lanka has vast diversity and endemicity of both flora and fauna. The Mahaweli River is the longest river and it originates from the central highlands and flows through the wet, intermediate and dry zones of the country. It helps sustain a rich biological diversity. But, large extents along the river are yet to be explored for its rich biodivers...
Conference Paper

Ornamental fish industry is an important component of aquaculture. A high percentage of the aquaculture production of ornamental fish targets freshwater species. Two of the most common freshwater ornamental species are the Golden Carp, Cyprinus carpio and the Freshwater Angelfish, Pterophyllum scalare. Though there is sufficient information on the...

Question
(Like we use munsell colour charts)
Are there any published article used that method for their taxonomical identification ?
Question
I am confused, there are lots of digestion procedures in the Web (such as Ammonium acetate method, HCl+HNO3, HCL+H2SO4, etc.).
