A total solar eclipse of the longest duration in the 21st century was announced to occur in the morning of 22nd July, 2009. As such a study on the effects of that solar eclipse on some animals was carried out at and near Pavana river dam, Akurdi, Pune. Observations were taken ad libitum (Altmann,1974) on some of the animals the day before the eclipse in the evening and the next day from early morning and also the subsequent day in the morning.

Rainwater harvesting consists of three basic elements — collection area (rooO, conveyance system (pipes) and storage facilities (tank or cistern). Rainwater harvesting systems need few skills and little supervision to operate. If water is to be used for drinking purpose, filtration or chlorination is required. An area of major concern is prevention of contamination of tank during construction and while it is being replenished during rainfall. Successful rainwater harvesting projects are generally associated with communities that consider water supply a priority. Policy level changes by concerned authorities can also be helpful in bringing the desired change.Keywords

Tiger has been once again in the news due to its disappearance in Sariska Tiger Reserve in Rajasthan. According to Global Tiger Forum (www.giobaltiger.org/population.htm), there were only 5700 to 7000 tigers of five subspecies left in the 14 tiger range countries in 2000/ 2001. out of which tiger population in India was estimated to be between 3000 and 3800. There have been studies on various aspects of tiger (Kenny et al., 1995; Noweii, 2000; Karanth and Nichols, 1998a; Karanth and Nichols, 1998b). Its environmental economics has also been studied (Damania et al., 2003). There appears to be no earlier work encompassing human health, economics and cultural aspects in relation to tiger conservation. Therefore, in the present communication, an attempt has been made to highlight tiger conservation in the light of pressing human needs pertaining to health, economics and culture, by synthesizing relevant information from available sources.- Play Behaviour in Free-Living Langur (Semnopithecus entellus) Infants

Piny behaviour in free-living langurs has been studied at Ambagnrh Reserve Forest, near Jaipur, India using focal sampling (Altmann, 1974) for 317 hours on a unimale group of langurs of 102 individuals. Infants were classified as young (dark pelage, birth < 6 months) and old (grey pelage, 6 months to 12-15 months). Observations were recorded in 3 states: infant with mother (state 0), infant less than 2 feet away from mother (state 1) and infant more than 2 feet away from mother (state 2). Unlike old infants, young infants played while on mother and old infants played away from mother and in state 2, play alone, play with other infant and play with juvenile differed significantly (x2 = 18.01, df = 2, p < 0.01). Both natural and sexual .selection seem to have played a role. Those patterns have evolved, which are adaptive. Play is replaced by grooming (which strengthens social bonding) in non-human primate and socialization in humans.These traits help in selecting potential mates. Comparison of human and langur infants indicates that young langur infants are comparable to 1st year and toddlers while old langur infants are similar in play profile to preschoolars and elementary . Influences of habitat quality on play behaviour in primates have been discussed.Keywords

A classified list of the small and medium sized cats so far known from the Subfamily Felinae (Mammalia : Carnivora: Feidae) is hereunder provided for the Asian region for ready reference as these are facing tremendous threats due to habitat loss and wide use of fur for export trade. India has a total of 390 mammal species of the world total of 4309 species (Alfred, Das and Sanyal, 1998). However, the present list comprising of 12 species under 5 genera is based on Wilson and Reder (1993). Other works such as Corbet and Hill (1992) are also consulted as the reference literature.References

India has a total of 390 mammal species of the world total of 4309 species (Alfred, Das and Sanyal, 1998). The subfamily Pantherinae diverged from Felinae between 6 and 10 million years ago (Johnson et al., 2006). It has three genera namely Panthera, Neofelis and Uncia. Members of this mammalia subfamily facing threats due to habitat loss and poaching for use of various body parts in trade. A checklist of seven species belonging to the Subfamily Pantherinae for the Asian region is provided herein based on Wilson and Reder (1993). Other works such as Corbet and Hill (1992) are also consulted as the reference literature.References

Marine Mammals (seals, whales and walruses) constitute 128 species in the world (Pompa et al., 2011), of which India has 31 species, comprising of 30 species of Cetacea and one species of Sirenia (Padmanaban and Dinesh, 2011). Wilson and Reeder (1993) have given an extensive account of Cetacea and Sirenia. According to Alfred et al.(1998) India has 29 species of Order Cetacea and 1 species of Order Sirenia out of the total of 390 species of mammals found in India. Maharashtra state has a coastline of 850 km on its western side and a marine wildlife sanctuary at Malvan in Sindhudurg district. A perusal of literature reveals that this State with its long coastline supports a considerable number of species of marine mammals.References
