TAXONOMIC STUDIES from RODENT OUTBREAK AREAS in the CHITTAGONG HILL TRACTS Nikhil
Bangladesh J. Zool. 46(2): 217-230, 2018 ISSN: 0304-9027 (print) 2408-8455 (online) NEW RECORDS OF RODENT SPECIES IN BANGLADESH: TAXONOMIC STUDIES FROM RODENT OUTBREAK AREAS IN THE CHITTAGONG HILL TRACTS Nikhil Chakma*, Noor Jahan Sarker, Steven Belmain1, Sohrab Uddin Sarker, Ken Aplin2 and Sontosh Kumar Sarker3 Department of Zoology, University of Dhaka, Dhaka-1000, Bangladesh Abstract: Rodents are regarded as crop pests, significant reservoirs and vectors for many zoonotic diseases around the world. Basic taxonomic information of rodents present in a locality can help understand which species are responsible as crop pest in that habitat. The phenomenon of the 50-year cycle of gregarious bamboo flowering and rodent outbreaks in the Chittagong Hill Tracts (CHT) of Bangladesh, rodents trapping were carried out in four habitats from March, 2009 to December, 2011 in Ruma upazila of Bandarban hill district. Variety of traps were used to capture small mammals. The captured species were measured and identified using taxonomical dichotomous keys and DNA bar-coding performed in Australia. A total of 14 different small mammalian species were captured of which nine belonging to the Muridae family, and one species each of Spalacidae, Sciuridae, Tupaiidae and Soricidae families. The dominant small mammal species captured were Rattus rattus (54.06%) followed by Mus musculus (26.39%), Rattus nitidus (10.98%), Suncus murinus (5.45%), Mus terricolor (1.09%), Mus cookii nagarum (0.97%), Cannomys badius (0.16%), Leopoldamys edwardsi (0.12%), Berylmys bowersi (0.12%), Vernaya fulva (0.08%), Rattus andamanensis (0.08%), Tupaia glis (0.04%) and Callosciurus pygerythrus (0.04%). -

A Phylogeographic Survey of the Pygmy Mouse Mus Minutoides in South Africa: Taxonomic and Karyotypic Inference from Cytochrome B Sequences of Museum Specimens
A Phylogeographic Survey of the Pygmy Mouse Mus minutoides in South Africa: Taxonomic and Karyotypic Inference from Cytochrome b Sequences of Museum Specimens Pascale Chevret1*, Terence J. Robinson2, Julie Perez3, Fre´de´ric Veyrunes3, Janice Britton-Davidian3 1 Laboratoire de Biome´trie et Biologie Evolutive, UMR CNRS 5558, Universite´ Lyon 1, Villeurbanne, France, 2 Evolutionary Genomics Group, Department of Botany and Zoology, University of Stellenbosch, Stellenbosch, South Africa, 3 Institut des Sciences de l’Evolution de Montpellier, UMR CNRS 5554, Universite´ Montpellier 2, Montpellier, France Abstract The African pygmy mice (Mus, subgenus Nannomys) are a group of small-sized rodents that occur widely throughout sub- Saharan Africa. Chromosomal diversity within this group is extensive and numerous studies have shown the karyotype to be a useful taxonomic marker. This is pertinent to Mus minutoides populations in South Africa where two different cytotypes (2n = 34, 2n = 18) and a modification of the sex determination system (due to the presence of a Y chromosome in some females) have been recorded. This chromosomal diversity is mirrored by mitochondrial DNA sequences that unambiguously discriminate among the various pygmy mouse species and, importantly, the different M. minutoides cytotypes. However, the geographic delimitation and taxonomy of pygmy mice populations in South Africa is poorly understood. To address this, tissue samples of M. minutoides were taken and analysed from specimens housed in six South African museum collections. Partial cytochrome b sequences (400 pb) were successfully amplified from 44% of the 154 samples processed. Two species were identified: M. indutus and M. minutoides. The sequences of the M. indutus samples provided two unexpected features: i) nuclear copies of the cytochrome b gene were detected in many specimens, and ii) the range of this species was found to extend considerably further south than is presently understood. -
Briefdefinitive Report
Brief Definitive Report ANALYSIS OF RESTRICTION FRAGMENT LENGTH POLYMORPHISM IN LYMPHOKINE GENES OF NORMAL AND AUTOIMMUNE MICE BY GUNTHER RICHTER, ZHIHAI QIN, TIBOR DIAMANTSTEIN, AND THOMAS BLANKENSTEIN From the Freie Universitat Berlin, Klinikum Steglitz, Institut fur Immunologie, 1000 Berlin 45, Federal Republic of Germany The genetic origin for the lupus-like disease in (NZB x NZW)F1, MRL/lpr or BxSB mice is largely unknown (reviewed in reference 1) . The mice develop symp- toms such as generalized B cell hyperactivation, early IgM to IgG class switch, or functional abnormalities in the CD4+ T cell subpopulation indicating the poten- tial involvement oflymphokines in the pathogenesis ofthe disease . This assumption is supported by findings such as decreased IL-2 and IL-2 receptor expression in (NZB x NZW)F1, MRL/lpr and BxSB mice (2), abnormal IL-1 transcripts (3), in- creased IL-4 expression (4), spontaneous transcription of IFN--y (5), and increased TNFa activity in MRL/lpr mice (6) . In contrast, TNFa production was found to be decreased in NZW and (NZB x NZW)F, mice (7) . The authors proposed that decreased TNFet production might be related to a mutation in the TNF-a gene as demonstrated by RFLP analysis . Moreover, administration of TNFa partially abolished the development of the disease . Altogether, the participation of lymphokines in autoimmunity suggested to analyze lymphokine genes at the genetic level . First, we sought to reevaluate the relevance of the TNFa polymorphism in NZB by deter- mining the frequency of this allele in a large number of laboratory and wild mice and found that the TNFa allele ofNZW is inherited in most normal inbred strains and wild mice arguing against an involvement of the NZW TNFa gene as a causal agent in the development of lupus in (NZB x NZW)Fi hybrids . -

An Experimental Study with Micromys Minutus
Bachelor’s degree in Biology Final dissertation project Análise da dieta de pequenos mamíferos: un traballo experimental con Micromys minutus Análisis de dieta de pequeños mamíferos: un trabajo experimental con Micromys minutus Diet analysis of small mammals: an experimental study with Micromys minutus Anxo Pensado Moreira July, 2018 Academic supervisor: Sergio Rodríguez Roiloa ABSTRACT The ongoing growth of the human population and human activities have caused a rapid loss of biodiversity. Species play an important role in the ecosystem functioning. Thus, in order to conserve them, detailed insight into their biology is crucial. The Harvest mouse (Micromys minutus) is an understudied species whose populations across the UK have undergone an apparent decline of the 71 % over the past 18 years. Furthermore, there seems to be little information available on the diet of this species, which can be essential to improve welfare guides for captive populations as well as for future conservation actions for wild populations. Thereby, the aim of the present study was to shed some light on the diet of a captive population of Micromys minutus at the Wildwood Trust by assessing their (1) dietary preferences, (2) potential sex differences, (3) feeding time patterns and (4) intake rates. In order to do so, 5 individuals of Harvest mice were presented with different feeds and as a result their consumptions over a period of 14 days were obtained. Posteriorly, data was analysed by means of variance analysis (ANOVA) performed with SPSS, showing significant differences in the food intake of Micromys minutus depending upon food type and feeding time effects. The study revealed that the mice preferred blackberries, canary seeds, dried meal worms, naked oats and safflowers over white and red millet, although males had a higher consumption of dried meal worms and naked oats, whilst females preferred safflowers. -
Evolutionary Characterization of a Y Chromosomal Sequence Conserved in the Genus Mus
Genet. Res., Camb. (1988), 52, pp. 145-150 With 5 text-figures Printed in Great Britain 145 Evolutionary characterization of a Y chromosomal sequence conserved in the genus Mus YUTAKA NISHIOKA Department of Biology, McGill University, Montreal, Quebec, Canada H3A IBI (Received 8 October 1987 and in revised form 26 January 1988) Summary The extent of accumulation of mouse Y chromosomal repetitive sequences generally correlates with the known phylogenetic relationships in the genus Mus. However, we describe here a M. musculus Y chromosomal repetitive sequence, designated as ACClfl, whose accumulation patterns among eight Mus species do not correspond to their phylogenetic relationships. Although male-specific hybridization bands were present in all the species examined, significant accumulation (^ 200 copies) in the Y chromosomes was found in M. minutoides (subgenus Nannomys), M. pahari (subgenus Coelomys) and M. saxicola (subgenus Pyromys) as well as in the three closely related species M. hortulanus, M. musculus and M. spretus that belong to the subgenus Mus. Unexpectedly, the Y chromosomes of M. caroli and M. cookii (both subgenus Mus) had considerably reduced amounts of ACClfl-related sequences. Furthermore, in rats {Rattus norvegicus) the major accumulation sites appear to be autosomal. These observations suggest that caution must be taken in the interpretation of data obtained with repetitive sequences that have evolved quickly. 1.

Box 1346 Ann Arbor, Ml 48106-1346 Abstract Fvl is a gene of mice known to restrict the replication of Murine Leukaemia virus (MLV) by blocking integration by an unknown mechanism. The gene itself is retroviral in origin, and is located on the distal part of chromosome 4. The sequence of markers known to flank Fvl in the mouse was used to identify sequence from the human homologues of these 2 genes. The construction of primers to these sequences permitted the screening of 2 YAC and a PAC human genomic libraries for clones containing either of these genes. The YAC libraries were negative for both markers. -
The Testis-Determining Gene, SRY, Exists in Multiple Copies in Old World Rodents
Genet. Res., Camb. (1994), 64, pp. 151-159 With 6 text-figures Copyright © 1994 Printed in Great Britain 151 The testis-determining gene, SRY, exists in multiple copies in Old World rodents CLAUDE M. NAGAMINE Department of Cell Biology, Vanderbilt University School of Medicine, Medical Center North, Room T2216, Nashville, TN USA 37232-2175 (Received 19 July 1994) Summary SR Y is a unique gene on the Y chromosome in most mammalian species including the laboratory mouse, Mus musculus, and the closely related European wild mouse species M. spicilegus, M. macedonicus, and M. spretus. In contrast, SR Y is present in 2-6 copies in the more distantly related Asian mouse species M. caroli, M. cervicolor, and M. cookii and in 2—13 copies in the related murid species Pyromys saxicola, Coelomys pahari, Nannomys minutoides, Mastomys natalensis, and Rattus norvegicus. Copy numbers do not correlate with known phylogenetic relationships suggesting that SR Y has undergone a rapid and complex evolution in these species. SRY was recently proposed as a molecular probe for phylogenetic inferences. The presence of multiple SR Y genes in a wide range of murid species and genera, and at least one cricetid species, necessitates caution in the use of SR Y for phylogenetic studies in the Rodentia unless it is ascertained that multiple SR Y genes do not exist. family whose signature or characteristic amino acid 1.
