The Beaver's Phylogenetic Lineage Illuminated by Retroposon Reads
www.nature.com/scientificreports OPEN The Beaver’s Phylogenetic Lineage Illuminated by Retroposon Reads Liliya Doronina1,*, Andreas Matzke1,*, Gennady Churakov1,2, Monika Stoll3, Andreas Huge3 & Jürgen Schmitz1 Received: 13 October 2016 Solving problematic phylogenetic relationships often requires high quality genome data. However, Accepted: 25 January 2017 for many organisms such data are still not available. Among rodents, the phylogenetic position of the Published: 03 March 2017 beaver has always attracted special interest. The arrangement of the beaver’s masseter (jaw-closer) muscle once suggested a strong affinity to some sciurid rodents (e.g., squirrels), placing them in the Sciuromorpha suborder. Modern molecular data, however, suggested a closer relationship of beaver to the representatives of the mouse-related clade, but significant data from virtually homoplasy- free markers (for example retroposon insertions) for the exact position of the beaver have not been available. We derived a gross genome assembly from deposited genomic Illumina paired-end reads and extracted thousands of potential phylogenetically informative retroposon markers using the new bioinformatics coordinate extractor fastCOEX, enabling us to evaluate different hypotheses for the phylogenetic position of the beaver. Comparative results provided significant support for a clear relationship between beavers (Castoridae) and kangaroo rat-related species (Geomyoidea) (p < 0.0015, six markers, no conflicting data) within a significantly supported mouse-related clade (including Myodonta, Anomaluromorpha, and Castorimorpha) (p < 0.0015, six markers, no conflicting data). Most of an organism’s phylogenetic history is fossilized in their heritable genomic material. Using data from genome sequencing projects, particularly informative regions of this material can be extracted in sufficient num- bers to resolve the deepest history of speciation. -
Hopping and Running on Two Legs Or Four from R
Nature Vol. 287 18 September 1980 187 Hopping and running on two legs or four from R. McNeil/ Alexander MOST mammals run on all fours but some run on just two legs (like men) or hop (like kangaroos). Some birds run, some hop and some do both. What are the relative merits of the different gaits? Do they differ in energy cost? Energy costs of running and hopping can be inferred from measurements of oxygen consumption. Some of the difficulties of physiological experimentation on moving animals can be avoided by training the Dipodomys deserti hopping on a moving belt to assess energy consumption. Experimental details animal to run on a moving belt as are given by Thompson et al. on p.223 of this issue of Nature. shown.

Namibia, 2018
Nambia and little bits of Botswana, Zimbabwe, and Zambia, July-August 2018 Michael Kessler In 1994, my wife Elke and I did our first joint trip to Namibia, spending 3 weeks mainly in the arid western parts of the country and seeing such goodies as Brown Hyena, Caracal, Black Mongoose, Honey Badger, 3 species of sengis, and Southern African Porcupine. In 2010, we made our first family trip to Africa to KwaZulu Natal, seeing much of the large game. So now we decided to return to Namibia with the family, with the aim of exploring some new areas and searching out the less easily seen species. Time and budget limited the trip to about 2½ weeks and after some deliberation, we settled on the following sites: Sesriem + Sossusvlei for the dunes; Walvisbay for Heaviside’s Dolphin + Welwitschia; Erindi for African Wild Dog and the other game; Toko Lodge for the night drives, especially for Aardvark; Etosha only briefly for the amazing wildlife spectacle; Mahango for the Okavango specials (birds and mammals); and Victoria Falls for, well, the falls. This resulted in the following Itinerary: 25.7: Left Zurich in the evening, arriving on 26.7.: am in Jo’burg, followed by a connecting flight to Windhoek where we picked up the rental car, did some grocery shopping, and fell into our beds at Arebbusch Lodge on the southern outskirts of the city. 27.7.: Long drive to Desert Homestead Lodge at Sesriem. 28.7.: am: visit to Sossusvlei; pm: Cessna flight over the dunes, followed by a night drive back to the lodge, seeing some Bat-eared Foxes. -

Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 27 March 2020 doi:10.20944/preprints202003.0410.v1 Abstract The world is puzzling over the origin of the current outbreak of the coronavirus disease (COVID-19) that is caused by a novel coronavirus-2019 (2019-nCoV). As of 25th March 2020, the World Health Organization has reported 4,14,179 confirmed cases and 18,440 confirmed deaths in total due to COVID-19. To this end, two unique mammals namely bats and pangolins are being investigated for their potential link to COVID-19. However, the evidence so far gathered in this context is far from clear. This paper aimed to: (i) enlighten the major aspects of life of bats and pangolins; (ii) briefly discusses their potential link to COVID-19; and also (iii) to highlight the way forward. The outcomes may contribute to future research on the subject.

Chapter 15 the Mammals of Angola
Chapter 15 The Mammals of Angola Pedro Beja, Pedro Vaz Pinto, Luís Veríssimo, Elena Bersacola, Ezequiel Fabiano, Jorge M. Palmeirim, Ara Monadjem, Pedro Monterroso, Magdalena S. Svensson, and Peter John Taylor Abstract Scientific investigations on the mammals of Angola started over 150 years ago, but information remains scarce and scattered, with only one recent published account. Here we provide a synthesis of the mammals of Angola based on a thorough survey of primary and grey literature, as well as recent unpublished records. We present a short history of mammal research, and provide brief information on each species known to occur in the country. Particular attention is given to endemic and near endemic species. We also provide a zoogeographic outline and information on the conservation of Angolan mammals. We found confirmed records for 291 native species, most of which from the orders Rodentia (85), Chiroptera (73), Carnivora (39), and Cetartiodactyla (33). There is a large number of endemic and near endemic species, most of which are rodents or bats. The large diversity of species is favoured by the wide P.

The Feasibility of Reintroducing African Wild Dogs (Lycaon Pictus) Into the Great Fish River Nature Reserve, Eastern Cape, South Africa
The feasibility of reintroducing African wild dogs (Lycaon pictus) into the Great Fish River Nature Reserve, Eastern Cape, South Africa. A thesis submitted in fulfilment of the requirements for the degree of MASTER OF SCIENCE of RHODES UNIVERSITY By SAMANTHA KARIN PAGE February 2014 Abstract With a declining population of roughly 3000-5000 individuals in Africa, African wild dogs (Lycaon pictus) are one of the most endangered carnivores in the world. As the global human population expands, it is becoming increasingly unlikely that large portions of land will be set aside for conservation, especially in developing countries. Thus, recent wild dog conservation efforts in South Africa have concentrated on establishing a managed metapopulation. A metapopulation is a group of geographically isolated subpopulations of a species that are managed (using supplementation and harvesting) to mimic natural gene flow. The Great Fish River Nature Reserve (GFRNR) in the Eastern Cape Province of South Africa has been identified as a potential reserve to become part of the national wild dog metapopulation. My research aimed to conduct a feasibility assessment of the long-term (~ 25 years) success of a wild dog reintroduction into the GFRNR. This assessment included biological modelling of wild dogs and their expected prey, and determining the potential anthropogenic threats to wild dogs on the private and communal land surrounding the reserve. I used VORTEX population modelling and determined that the GFRNR is likely to have a wild dog carrying capacity of ~22 individuals. Using a 25-year modelling simulation, the most appropriate wild dog reintroduction scenario would be to reintroduce six females and four males initially and supplement the population with one female and two males in years 3, 10, 15 and 23. -
