The study involves survey of amphibian and reptile in and around Gulbarga University Campus. Survey was conducted from Jan 2012 to March 2013. The survey methods involved careful visual estimation of amphibians and reptilian in all the possible habitats present in the study area. The objective of the study included evaluate of species composition, relative abundance and distribution of amphibian and reptile of the chosen area. During survey a total of 16 species of herpetofauna identified belonging to 12 families, which includes 9 species of snakes, 4 species amphibians, 3 species of lizards

Abstract Background: The species composition, relative abundance and distribution of rodents were studied in Wof-Washa Natural State Forest, Ethiopia from December 2016 to May 2017 during dry and wet seasons. A total of 49 Sherman live traps were set per grid at 10 m intervals in permanent 4900 m2 (70mx70m) live trapping grids established in intact forest, disturbed forest, Erica woodland, plantation forest and Farmland habitats. Result: A total of 621 individuals of rodents were captured in 2,560 trap nights by using both live traps and snap traps. Seven species of rodents in family Muridae were recorded. Out of the total rodents caught in the study period, Stenocephalemys albipes, Pelomys harringtoni and Lophuromys flavopunctatus are endemics to Ethiopia. Plantation forest had the highest mean trapping success whereas the lowest trap success was in the Erica woodland. The distribution of rodent species was significantly differed (P<0.05) among studied habitats. Higher trap success was recorded in dry season (26.2) than the wet season (24.4). The highest value of Shannon index was recorded in plantation forest (H’ = 1.82) followed by farmland habitat (H’ =1.67) during the wet season and the lowest value was observed in the intact forest (H’ = 0.67) and Erica woodland (H’ = 0.67) during the dry season. From the total catch, adults comprised 260(41.9%), sub-adults 248(39.9%) and juveniles 113(18.2%).Conclusion: The present study provides the first valuable demonstration on the species composition, relative abundance and distribution of rodents in the WWNSF. Further monitoring and inventory of small mammals is warranted to document and conserve the different endemic and endangered rodent species to designing important biodiversity management plan in the area.

Abstract. Rosales R, Lillo E, Alcazar SM, Colita L, Caballero J, Malaki AB. 2020. Species composition, relative abundance, and distribution of land snail species in Mt. Lantoy Key Biodiversity Area, Cebu, Philippines. Biodiversitas 21: 5438-5447. This study aimed to establish an inventory of land snails in Mt. Lantoy, Cebu Island, Philippines. A two-person team conducted sampling on eight permanent plots with an elevation range of 182 m-691 m. The study has listed a total of 872 individuals represented by 25 species belonging to 15 genera and nine families. Seven families belong to the air-breathing pulmonate group, Order Stylommatophora: Bradybaenidae, Camaenidae, Trochomorphidae, Achatinidae, Ariophantidae, Helicarionidae, Helicinidae. Two families were under the prosobranch group, Order Caenogastopoda: Cyclophoridae, and Pupinidae. The Cyclophoridae was the richest family with five species, followed by Bradybaenidae, Camaenidae, Helicinidae, having four species. The Trochomorphidae and Helicarionidae have three species. The Pupinidae has two species, while the Achatinidae and Ariophantidae has one species each. There were three (3) endemic and ten (10) new island record species collected and identified with four (4) species that were classified as rare. Rysotta otaheitana Ferussac 1821 was the most abundant, representing 25.22% of the total number of individuals. The Leptoma nitidum ancilis Bartsch 1918 has the widest geographical distribution with a constancy rate of 100%. Widespread species appear to be more abundant, while other species were geographically restricted in few study areas.

A study on the ecology of phlebotomine sandfly fauna in a restricted focus of cutaneous leishmaniasis in northern Venezuela was undertaken in order to investigate the species responsible for the transmission. The study area and catching methods for phlebotomine sandflies are described. A total of 9,061 females and 1,662 males were collected during a year-term study. 12 species of Lutzomya and 1 species of Brumptomya sp. were identified. Absolute and relative abundance and ocurrence for each species were determined. The rel ative occurrence allowed to distinguish the common species, viz. L. panamensis, L. ovallesi, L. gomezi, L. tinidadensis, L. atroclavata, L. cayennensis, L. shannoni and L. olmeca bicolor from the rare species vis., L. punctigeniculata, L. rangeliana, L. evansi and L. dubitans. General comments on the species composition of the sandfly fauna in this locality are made.
