A total four specimens of adult birds are obtained for examination from natural mortalities in rural, urban and forest habitats of Central Saurashtra of Western India. All the morphological features of species are observed in living as well as in freshly preserved (40% formalin sol.) with the help of a pair of binoculars in field and in laboratory with the help of Stereo-zoom dissecting microscope and camera-Lucida are used for illustrations. Usually, the Eurasian Collared Dove chiefly feeds upon plant matters i.e. grain and seed in various microhabitats like vegetation layers, crop fields, grass lands, foliage, garbage and food offering ...

The lingua is suitably modified for this purpose or does not intent the present work to understand it. The anatomical details of the lingual apparatus and their associated epidermal, musculature, and osteological elements of Indian doves (Aves: Columbidae) Eurasian collared dove (Streptopelia decaocto) and laughing dove (Stigmatopelia senegalensis) with comparison are lacking in the literature. Results A total of eight (n = 8/species) freshly preserved adult specimens with natural mortalities from Central Saurashtra, Western India, were examined. All the morphological features of species were observed in living as well as in preserved with the help of a pair of binoculars in the field and in the laboratory with stereo zoom dissecting microscope and camera lucida which are used for illustrations.

The study area was divided into four sections: North (N), East (E), South (S) and West (W) and surveyed over 18 visits (four line transects/visit). We recorded a total of 82 bird species from 67 genera, 40 families and 16 orders. Of these 57 species were terrestrial and 25 aquatic. By population size the most abundant birds were members of Columbidae (28%), Sturnidae (13%), and Charadridae (8%). Seventy per cent of birds observed (n=7665) were classed as very common and 2% (n=261) as very rare. Species density (S/N = 3.39) and population density (n/N = 196) were at their maximum in December. Ecological indices on temporal base reveal high species richness and Simpson diversity (1/D =17.0 and 1-D= 0.942) in August and November and Shannon diversity was high (H’=3.275) in November during study period.

Data recorded by random sampling (Total Visits = 153, Sampling unit (N) = 236) from rural to urban gradient level of Jamnagar city; 4 to 8 times survey per month using plots and strip transects during day and night. The presence of 39 herpetofaunal species belong to 13 families reveal 17 species of anurans dominated by family - Dicroglossidae (568) and 22 species of reptiles by Agamidae (131). Skipper Frog (Euphlyctis cyanophlyctis) was most abundant species, single time sighted species was Jerdon’s Bull Frog (Hoplobatrachus crassus) and 01 endangered species Nilgiri Frog (Minervarya nilagirica). From reptiles most abundant species was Common Garden Lizard (Calotes versicolor) and very common species Northern House Gecko (Hemidactylus flavi...

This study reports systematics, species composition, conservation status, occurrence and distribution, diversity indices and Photographic documentation. Sampling methodology includes field survey by Visual encounter survey (VES) method, using Line transects (N= 21) and various sizes plotting (N= 32) at random, 2 or 3 days per week, spent 09 hrs per day and night. Entire survey accomplishedwithin total sampling units N=53 under 25 visits, explored all the possible macro and microhabitat from rural to urban gradients. Identification based through morphological details on photographs, close examination andvocalization for anurans during field survey and various literatures. A total of 545 individuals record total 18 species of amphibians belong to06 genera and 03 families, while reptiles record total 19 species, 15 genera and 08 families. Conserv...

A preliminary survey was conductedduring August to October 2015 with respect to systematics, species composition, diversity indices and conservation status. Total 25 visits were undertaken for field survey by Visual encounter methods (VES) using Line transect andvarious sizes plotting at random exploring in all the possible microhabitats. All the sampling taxa were identified by various literatures throughphotographs under Photoshop and close observation during field survey. The results reveal total 14 Anuran species belong to 03 families and 07 genera. Familial population in member of family Dicroglossidae (05 genus and 11 species) represents first position among Bufonidae and Microhylidae. The most abundant species was Skipper Frog (Euphlyctis cyanophlyctis) and conservation status reports One Data-deficient species Short Webbed frog (Minervarya ...
