Patterson1 and Paul M. Velazco1, 2 1 Department of Zoology, Field Museum of Natural History, 1400 S. Lake Shore Dr, Chicago IL 60605-2496 USA. 2 Department of Biological Sciences, University of Illinois at Chicago, 845 W. Taylor St, Chicago IL 60607 USA ABSTRACT: Recent surveys in Peru’s Manu National Park and Biosphere Reserve uncovered a new species of hystricognath rodent, a spiny rat (Echimyidae) with dense, soft fur. Inhabiting Andean cloud-forests at 1900 m, the new rodent belongs to a radiation of “brush- tailed tree rats” previously known only from the Amazon, Orinoco, and other lowland river drainages. Phylogenetic analysis of morphology (cranial and dental characters) unambiguously allies the new species with species of Isothrix. -

Hystrix Africaeaustralis)
Reproduction in captive female Cape porcupines (Hystrix africaeaustralis) R. J. van Aarde Mammal Research Institute, University ofPretoria, Pretoria 0002, South Africa Summary. Captive females attained sexual maturity at an age of 9\p=n-\16months and con- ceived for the first time when 10\p=n-\25months old. Adult females were polyoestrous but did not cycle while lactating or when isolated from males. The length of the cycle varied from 17 to 42 days (mean \m=+-\s.d. 31\m=.\2\m=+-\6\m=.\5days; n = 43) and females experienced 3\p=n-\7 sterile cycles before conceiving. Pregnancy lasted for 93\p=n-\94days (93\m=.\5\m=+-\0\m=.\6days; N = 4) and litter intervals varied from 296 to 500 days (385 \m=+-\60\m=.\4;n = 10). Litter size varied from 1 to 3 (1\m=.\5\m=+-\0\m=.\66;n = 165) and the well-developed precocial young weighed 300\p=n-\400g (351 \m=+-\47\m=.\4g; n= 19) at birth. Captive females reproduced throughout the year with most litters (78\m=.\7%;n = 165) being produced between August and March. Introduction Cape porcupines (Hystrix africaeaustralis) inhabit tropical forests, woodlands, grassland savannas, semi-arid and arid environments throughout southern Africa. Despite this widespread distribution little attention has been given to these nocturnal, Old World hystricomorph rodents, which shelter and breed in subterranean burrows, rock crevices and caves. Some information on reproduction in female porcupines has been published on the crested porcupine (H. cristata) (Weir, 1967), the Himalayan porcupine (H. hodgsoni) (Gosling, 1980) and the Indian porcupine (H. -
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. -
Gliding Behavior of Japanese Giant Flying Squirrels (Petaurista Leucogenys)
Journal of Mammalogy, 83(2):553-562, 2002 GLIDING BEHAVIOR OF JAPANESE GIANT FLYING SQUIRRELS (PETAURISTA LEUCOGENYS) BRIAN J. STAFFORD,* RICHARD W.

We observed 150 glides. We were able to calculate glide ratios on 57 glides and airspeeds on 29 glides. Glide ratios (distance/faltitude lost]) averaged 1.87, and a glide ratio of 3•3.5 seems to represent an upper performance limit for P. leucogenys. Airspeeds (4.39•9.47 m/s) were substantially lower than reported in other studies, and glide angles were higher (17.74•34.99°). Aspect ratios of the animals in mid-glide averaged 1.42.

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.

Kaduna, Nigeria. Corresponding Author: Ahmad, IM Abstract: Background: Karyotypic studies were carried out on the African giant rat, Cricetomysgambianus, Waterhouse-1840 with the aim of determining its chromosome diploid numbers and autosomal fundamental numbers. Methods: The chromosomes were prepared from the conventional bone marrow of two (2) African giant rats – a male and a female treated intra-peritoneally with 2 ml of 0.04% colchicines for 3 hours. Chromosomes in well spread mitotic metaphase cells were counted and measured using KaryoType computer software. Chromosomal numbers were identified. Ideograms were also constructed from the measurements. Data were collected and analysed using SPSS version 20. Results: A diploid chromosome number of 2n = 80 with an autosomal fundamental number (NFa) of 66 and 95 were obtained for the species of C. gambianus used in this study. The X chromosomes were medium-sized metacentric and small acrocentric while the Y chromosome was small acrocentric. Conclusion: Cricetomysgambianus was found to have an identifiable autosomal diploid number,The findings resembled those in Benin, Senegal, Niger, Cameroun and other countries. -
