The distribution of Bufotes latastii, a diploid green toad species, is analyzed based on field observations and literature data. 74 localities are known, although 7 ones should be confirmed. The range of B. latastii is confined to northern Pakistan, Kashmir Valley and western Ladakh in India. All records of “green toads” (“Bufo viridis”) beyond this region belong to other species, both to green toads of the genus Bufotes or to toads of the genus Duttaphrynus. B. latastii is endemic to the Western Himalaya. Its allopatric range lies between those of bisexual triploid green toads in the west and in the east. B. latastii was found at altitudes from 780 to 3200 m above sea level. Environmental niche modelling was applied to predict the potential distribution range of the species. Altitude was the variable with the highest percent contribution for the explanation of the species distribution (36 %). urn:lSid:zOobank.Org:pub:0C76EE11-5D11-4FAB-9FA9-918959833BA5 INTRODUCTION Bufotes latastii (fig. 1) iS a relatively cOmmOn green toad species which spreads in KaShmir Valley, Ladakh and adjacent regiOnS Of nOrthern India and PakiStan. -

The Herpetofauna of the Cubango, Cuito, and Lower Cuando River Catchments of South-Eastern Angola
Official journal website: Amphibian & Reptile Conservation amphibian-reptile-conservation.org 10(2) [Special Section]: 6–36 (e126). The herpetofauna of the Cubango, Cuito, and lower Cuando river catchments of south-eastern Angola 1,2,*Werner Conradie, 2Roger Bills, and 1,3William R. Branch 1Port Elizabeth Museum (Bayworld), P.O. Box 13147, Humewood 6013, SOUTH AFRICA 2South African Institute for Aquatic Bio- diversity, P/Bag 1015, Grahamstown 6140, SOUTH AFRICA 3Research Associate, Department of Zoology, P O Box 77000, Nelson Mandela Metropolitan University, Port Elizabeth 6031, SOUTH AFRICA Abstract.—Angola’s herpetofauna has been neglected for many years, but recent surveys have revealed unknown diversity and a consequent increase in the number of species recorded for the country. Most historical Angola surveys focused on the north-eastern and south-western parts of the country, with the south-east, now comprising the Kuando-Kubango Province, neglected. To address this gap a series of rapid biodiversity surveys of the upper Cubango-Okavango basin were conducted from 2012‒2015. This report presents the results of these surveys, together with a herpetological checklist of current and historical records for the Angolan drainage of the Cubango, Cuito, and Cuando Rivers. In summary 111 species are known from the region, comprising 38 snakes, 32 lizards, five chelonians, a single crocodile and 34 amphibians. The Cubango is the most western catchment and has the greatest herpetofaunal diversity (54 species). This is a reflection of both its easier access, and thus greatest number of historical records, and also the greater habitat and topographical diversity associated with the rocky headwaters. -

Breeding Activity of a Stream-Breeding Toad, Bufo Torrenticola
Japanese Journal of Herpetology 16(4): 117-128., Dec. 1996 (C)1996 by The HerpetologicalSociety of Japan Breeding Activity of a Stream-Breeding Toad, Bufo torrenticola HIROSHI TSUJI AND TAKEO KAWAMICHI Abstract: The breeding activity of the stream-breeding toad (Bufo torrenticola) was studied in Mie Prefecture for three years from 1990 to 1992. Aggregation in the main pool, which was intensively investigated, occurred explosively in early April for 12- 14 days. The oviposition period was 5-11 days in the main pool, and 14-17 days in the entire length of stream. First, many toads appeared on a particular section of the migration path, on their way to the stream. In about 300 individuals captured in the main pool, the males: female ratio was 2.0-2.4:1. The daily number of toads found in the main pool showed the normal distribution pattern with a sharp peak in the middle of the breeding period. Toads appeared to be most active during the nighttime. The onset of migration to the stream was affected by soil temperature rather than by air temperature; during the three years, maximum soil temperatures were 10.0-11.0℃, and minimum soil temperatures ranged 8.5-9.0℃ . Oviposition activity in the main pool in 1991 and 1992 occurred in the later half of the breeding period, when the minimum water temperature was above 10.0℃. Breeding activity, however, was not strongly associated with weather conditions, probably because breeding is performed underwater. Key words: Bufo torrenticola; Stream-breeding toad; Migration; Breeding Activity; Oviposition The genus Bufo has a wide distribution cover- (Maeda and Matsui, 1989). -

Competition and distribution model predictions vary based on dominance hierarchies, but most assume differences in dominance are constant across habitats. More recent evidence suggests dominance and competitive advantages may vary based on habitat. We quantified dominance interactions between two species of sharks Carcharhinus amblyrhynchos and Carcharhinus melanopterus, across two different habitats, fore reef and back reef, at a remote Pacific atoll. We used Baited Remote Underwater Video (BRUV) to observe dominance behaviors and quantified the number of aggressive interactions or bites to the BRUVs from either species, both separately and in the presence of one another. Blacktip reef sharks were the most abundant species in either habitat, and there was significant negative correlation between their relative abundance, bites on BRUVs, and the number of grey reef sharks. Although this trend was found in both habitats, the decline in blacktip abundance with grey reef shark presence was far more pronounced in fore reef habitats. We show that the presence of one shark species may limit the feeding opportunities of another, but the extent of this relationship is habitat specific. Future competition models should consider habitat-specific dominance or competitive interactions. -

A Plant Ecological Study and Management Plan for Mogale's Gate Biodiversity Centre, Gauteng
A PLANT ECOLOGICAL STUDY AND MANAGEMENT PLAN FOR MOGALE’S GATE BIODIVERSITY CENTRE, GAUTENG By Alistair Sean Tuckett submitted in accordance with the requirements for the degree of MASTER OF SCIENCE in the subject ENVIRONMENTAL MANAGEMENT at the UNIVERSITY OF SOUTH AFRICA SUPERVISOR: PROF. L.R. BROWN DECEMBER 2013 “Like winds and sunsets, wild things were taken for granted until progress began to do away with them. Now we face the question whether a still higher 'standard of living' is worth its cost in things natural, wild and free. For us of the minority, the opportunity to see geese is more important that television.” Aldo Leopold 2 Abstract The Mogale’s Gate Biodiversity Centre is a 3 060 ha reserve located within the Gauteng province. The area comprises grassland with woodland patches in valleys and lower-lying areas. To develop a scientifically based management plan a detailed vegetation study was undertaken to identify and describe the different ecosystems present. From a TWINSPAN classification twelve plant communities, which can be grouped into nine major communities, were identified. A classification and description of the plant communities, as well as, a management plan are presented. The area comprises 80% grassland and 20% woodland with 109 different plant families. The centre has a grazing capacity of 5.7 ha/LSU with a moderate to good veld condition. From the results of this study it is clear that the area makes a significant contribution towards carbon storage with a total of 0.520 tC/ha/yr stored in all the plant communities.

While the cane toad is native to South America, the Asian spined toad is native to Asia. Much like the cane toad, the Asian spined toad is highly fecund, producing up to 40,000 eggs per clutch. It is also poisonous, has a generalist diet and is well adapted for life in urban areas.
