Waits, L.P., Paetkau, D., 2005. The partial, resulted in successful amplification of 45 out of 55 (82%) samples. Universal CytB primers revealed a low percentage of amplified otter species from faecal samples (species specific amplification success of 10.9%) whereas, the partial CytB primer set resulted in successful amplification of 45 out of 55 (82%) samples. S. Afr. The word 'aonyx' means clawless, derived from the prefix a- ("without") and onyx ("claw/hoof"). About 43 000 ants were sampled in 256 locations throughout the Ugandan foot slopes of Mt. ‘‘-’’ indicate gaps present in the sequence. primers; CytB.S.A3 F: TGCCTGTTCCTACACGT and CytB.S.A3 R: AGTTAGTGATTACGGTTG, were developed, gene. In this study, non-invasive molecular methods were used to investigate the abundance and spatial organisation of otters (Lutra lutra) in Kinmen. COI gene sequences of all samples of the two species are highly identical at 99-100%. The mystery was solved when otters were caught on camera feasting on the small sharks, picking out select organs for consumption. DNA barcoding in the cycadales: testing the potential of proposed barcoding markers for species. In fact, it is ranked fifth among all African nations in terms of the highest diversity of amphibian species. The southern river otter Lontra provocax is an endangered species. This is a list of the mammal species recorded in South Africa.There are 299 mammal species in South Africa, of which two are critically endangered, eleven are endangered, fifteen are vulnerable, and thirteen are near threatened. Results from HRM analyses with ITS primers shows that the two Ophiocordyceps species (Ophiocordyceps sinensis and Ophiocordyceps militaris) were easily differentiated. that this protocol will also be able to identify samples from this species. Their diet was more varied at Mkambati (15 prey species) than Dwessa (7 species). BMC Genomics. Cape Otter Behaviour The Cape otter As the name suggests, these Otters don’t have claws. The Spotted-neck otter is not as widely distributed as the Cape clawless otter since it is limited to inland waters in the eastern part of South Africa. Mol. Threats: habitat d… The assessment, carried out by the South African National Biodiversity Institute (Sanbi) and fynbos experts, revealed that 47% (165 of 353 species) of local species face extinction. In this study, we compared results obtained for universal and partial CytB primer sets on collected spraint and tissue control samples. This paper. Comparing morphological characteristics and DNA barcoding of two goby species Butis butis and Butis... Multiuse of Bar-HRM for Ophiocordyceps sinensis identification and authentication. Amplicons for sequencing were generated using the above mentioned Dreamtaq PCR mastermix protocol. They occur in a wide variety of environments and most aquatic habitats, from freshwater lakes to the marine littoral,and even in episodic rivers in arid areas,provided freshwater sources are adequate and … SOUTHERN AFRICAN MARINE LINEFISH SPECIES PROFILES B.Q. Land transformation for anthropogenic use is the leading cause of species decline globally. Meyer, C.P., Paulay, G., 2005. However, few species are able to succeed in anthropogenically disturbed environments. tempo and biogeographic history of a mammalian adaptive radiation. Otters have also been Extant Native Alison Kock, a marine biologist at South African National Parks, studied the remains of the shyshark carcass and said otters eat ‘the most nutritious parts of … Mol. Crossref. Due to the cryptic nature of these animals faecal samples, known as spraints, are the easiest way … The researchers propose that the otter’s role in this ancient ecosystem – to which it was unique –was like that of the living African clawless otter and the Asian small-clawed otter today. The PCR, Following sequence alignment using the ClustalW function in MEGA5, the National Center for Biotechnology Information. Mol. economic development. 6 (9), 869–876. ... 27 Species identification was conducted using developed partial CytB primers. Reduced stream flow or seasonal drying up of sources, resulting from increased human activities, can negatively affect continued otter occurrence along a coastline. Otters off the coast of South Africa have been caught catching sharks and eating their hearts, livers and male sex organs before discarding the rest of the body.. Over several months a number of shyshark carcases were found by rangers near Simon's Town in False Bay, South Africa with organs removed , Newsweek reported. There are however no fine-scale studies focusing on the actual distribution of these two species in urban areas. fragment (CC-Cape clawless otter, EO-European otter, ). A preliminary evaluation of the rela-tionship between fish availability and otter marking intensity was performed along 39 km of the River Sinni on one day. J. Wildl. The river otter's diet primarily consisted of crustaceans; however, rainfall and wetland subsystems influenced the frequency of fish and especially amphibians in the spraints collected. (NCBI) BLAST function was used to identify all possible GenBank reference samples (Eurasian otter, Alignment of the partial CytB gene. DNA samples were extracted from fresh spraints collected seasonally along two streams from February to November 2001 and genotyped using a panel of 7 microsatellites and the SRY gene. Estimated densities of adult A. capensis and L. maculicollis, based on mean numbers of holts used, were 1/3 -4km and 1/6-11km respectively. All images via Jacqui Smith, Save Our Seas Foundation Often found in freshwater bodies along the coastline, a Cape clawless otter is also known as an African clawless otter … The grouping observed in the study presented, here is supported by the phylogram published by. Distribution records for Spotted-necked Otter (Hydrictis maculicollis) within the assessment region Regional population effects: While we suspect that The discovery of a remnant population of the Recently, genetic techniques differentiating between African clawless otter and spotted-necked otter (Hydrictis maculicollis) faecal samples were developed by. Differentiation of two South African otter species (Aonyx capensis and Lutra maculicollis) from spraint based on partial CytB primer sets. A. capensis was generally more terrestrial than L. maculicollis. (eceived 6th July 2016, accepted 2nd September 2016) Abstract: Cape clawless otters Aonyx capensis and spotted-necked otters Lutra maculicollis were studied on three rivers in the Drakensberg Park, South Africa. Home South African Journal of Wildlife Research - 24-month delayed open access Vol. Evol. The ability to accurately iden-, 2015 Published by Elsevier B.V. Thus partial primers were developed that sequenced a 130 bp fragment of the gene. Sequence Navigator 1.01 (Applied Biosystems) was, used for initial sequence analysis of each individual specimen while the resulting sequence chromatograms were viewed and, edited in the Chromas programme which is embedded in MEGA 5 (. This, would, for example, influence the design of green corridors in urban environments, as the two species have different habitat. Elgon in the years 2014, 2015 and 2016. Using random encounter models, we estimated that the transformed area had the highest density of African clawless otters (8.2 ± 2.3 km−2), compared to otter densities at Verloren Vallei and Cobham Nature Reserve, South Africa, (natural areas) with estimated densities of 0.7 ± 0.2 km−2 and 2.1 ± 0.6 km−2 respectively. 56-70 : erratum Build a bridge and get over it : the effect of bridges over water on terrestrial animal presence Upper lips, sides of face, neck, throat, belly, and edge of ears Densities of clawless otters were between 1/2.5 km and 1/0.7 km. This species used to be known as Amblonyx cinereus, and before that as Aonyx cinerea. At 50% of the holts shelter was provided by cover only, and at the rest additional shelter was provided by burrows excavated by the otters themselves.
