Carapacial scute anomalies of star tortoise (Geochelone elegans) in Western India
Raju Vyas*
*E-mail: razoovyas@hotmail.com
The basic taxonomy and classification of reptile species and genera often use pholidotic characters. Despite that each species has a standard pattern, there are always deviant individuals in terms of scale number, shape, size, or color. Turtles are excellent models for the study of developmental instability because anomalies are easily detected in the form of malformations, additions, or reductions in the number of scutes or scales. The normal number of carapacial scutes in turtles is five vertebrals, four pairs of costals, and 12 pairs of marginals, a pattern known as “typical chelonian carapacial scutation”. Any deviation of vertebral, costal, or marginal scute numbers or their pattern represents an anomaly. Zangerl & Johnson (1957) documented scutation anomalies in 118 species of turtles belonging to seven families, with higher levels of carapace anomalies in aquatic species compared to semi-aquatic and terrestrial species.

Box turtles in and adjacent to Loktak Lake, Manipur – India
R.R. Singh* & K.J. Singh
*E-mail: princerobbin@gmail.com
Manipur is a biodiversity rich state located in the northeastern part of India that borders Myanmar. Situated within the western portion of the Indo-Burma biodiversity hotspot, the state has a large number of endemic and endangered species. The state is also prone to habitat destruction due to rapid clearing of forest for shifting cultivation, which is a common practice in the hill districts for agriculture and collection of firewood and timber. In the valley districts, the entire forest areas were converted to agricultural fields leaving only a few remaining green spaces, such as the sacred groves locally known as Umang Lais, small hillocks, and Keibul Lamjao National Park.

Historical land-use patterns in relation to conservation strategies for the Riverstone area, the Knuckles massif, Sri Lanka: insights gained from the recovery of anuran communities
Senarathge R. Weerawardhena* & Anthony P. Russell
*E-mail: zoosrw@kln.ac.lk
Agriculture on the Indian sub-continent dates back to the fourth and third millennia BC, but only in more recent times did its intensity escalate in a major way. During the colonial era, the British established that the hilly areas of Sri Lanka were suitable for the rearing of coffee (Coffea arabica), for which much of the arable land of the island was extensively cultivated. Later, however, resulting from the severe impact of “Coffee Rust,” caused by the fungus Hemileia vastatrix, the coffee industry of Sri Lanka declined dramatically. Former coffee plantations were abandoned, but are still distinguishable as damaged areas. The truncation of coffee growing on the island created vacant room for another cash-crop.

The Nasalis Affair
Lee E. Harding*
*E-mail: harding@sciwrite.ca
Baron Friedrich van Wurmb (1781) is credited with the first description of the proboscis monkey, endemic to Borneo, which he named Cercopithecus [now Nasalis] larvatus. This was in a paper read to The Society of Batavia, modern day Jakarta, Indonesia, and later published in the Society’s Memoirs. But he was not the first.

GROUP-SIZE AND AGE-SEX COMPOSITION OF NILGIRI LANGUR Trachypithecus johnii (PRIMATES: CERCOPITHECIDAE) IN INDIA

*E-mail: moni.roy8@gmail.com
Abstract
Group size and group composition of Nilgiri langur (Trachypithecus johnii) was studied in two habitats of Parambikulam Tiger Reserve, Kerala, India. Group size and age-sex composition data was collected during scan sampling, 18 monitoring transect lines, road-strip count, and direct encounter of the groups. Mean group size value significantly differ between moist deciduous forest and evergreen forest. Group size was varied from 2 to 22. The maximum group size, 22 was recorded in evergreen forest habitat. The mean group size of Nilgiri langur is less in moist deciduous forest and higher in evergreen forest.
Key words : Demographic parameters, colobines, Parambikulam Tiger Reserve, Western Ghats.
