  • Socioeconomic and Ecological Aspects of Field Rat Control in Tropical and Subtropical Countries Bans Kurylas
    SOCIOECONOMIC AND ECOLOGICAL ASPECTS OF FIELD RAT CONTROL IN TROPICAL AND SUBTROPICAL COUNTRIES BANS KURYLAS. Thai-German Rodent Control Project. German Agency for Technical Cooperation (GTZ), P.O. Box 9-34, Bangkok. Thailand. ABSTRACT: The vital question. as to the cause of the pennanent increase in field rat populations throughout most tropical and subtropical areas. has been the subject of researchers and fielcM!en during the past years, in the hope of finding an answer to this problem. Man has made his way through history wherein he was gradually able to renounce nature and establish his own man-made cultural frame. Unlike other marrmals. man has no natural instincts to guide him through life. Brain and spirit have to compensate for lack of. physical capabilities and instincts. Man was forced to change his natural surroundings in order to serve his special and ever-growing needs . Survival meant not only using nature but more so changing it in order to develop his culture. The field rat has become man's "cultural treader"! Myomorpha is the largest suborder of the Order Rodentia. Of the 1700 rodents known to man. more than 1100 belong to this group. The greater part of the Myomorpha species are found within two families, which are Cricetidae with about 567 species and Muridae with about 475 species. Most of these rodents live either in trees or under the ground. They rarely collide with man's interest. Only a few rodent species have become "field rats" and seem to dwell in and utilize man's cultural steppe. Some species have even become cosmopolitan and are found in Europe.

  • Learning About Mammals
    Learning About Mammals The mammals (Class Mammalia) includes everything from mice to elephants, bats to whales and, of course, man. The amazing diversity of mammals is what has allowed them to live in any habitat from desert to arctic to the deep ocean. They live in trees, they live on the ground, they live underground, and in caves. Some are active during the day (diurnal), while some are active at night (nocturnal) and some are just active at dawn and dusk (crepuscular). They live alone (solitary) or in great herds (gregarious). They mate for life (monogamous) or form harems (polygamous). They eat meat (carnivores), they eat plants (herbivores) and they eat both (omnivores). They fill every niche imaginable. Mammals come in all shapes and sizes from the tiny pygmy shrew, weighing 1/10 of an ounce (2.8 grams), to the blue whale, weighing more than 300,000 pounds! They have a huge variation in life span from a small rodent living one year to an elephant living 70 years. Generally, the bigger the mammal, the longer the life span, except for bats, which are as small as rodents, but can live for up to 20 years. Though huge variation exists in mammals, there are a few physical traits that unite them. 1) Mammals are covered with body hair (fur). Though marine mammals, like dolphins and whales, have traded the benefits of body hair for better aerodynamics for traveling in water, they do still have some bristly hair on their faces (and embryonically - before birth). Hair is important for keeping mammals warm in cold climates, protecting them from sunburn and scratches, and used to warn off others, like when a dog raises the hair on its neck.

  • A Dated Phylogeny of Marsupials Using a Molecular Supermatrix and Multiple Fossil Constraints
    Journal of Mammalogy, 89(1):175–189, 2008 A DATED PHYLOGENY OF MARSUPIALS USING A MOLECULAR SUPERMATRIX AND MULTIPLE FOSSIL CONSTRAINTS ROBIN M. D. BECK* School of Biological, Earth and Environmental Sciences, University of New South Wales, Sydney, New South Wales 2052, Australia Downloaded from https://academic.oup.com/jmammal/article/89/1/175/1020874 by guest on 25 September 2021 Phylogenetic relationships within marsupials were investigated based on a 20.1-kilobase molecular supermatrix comprising 7 nuclear and 15 mitochondrial genes analyzed using both maximum likelihood and Bayesian approaches and 3 different partitioning strategies. The study revealed that base composition bias in the 3rd codon positions of mitochondrial genes misled even the partitioned maximum-likelihood analyses, whereas Bayesian analyses were less affected. After correcting for base composition bias, monophyly of the currently recognized marsupial orders, of Australidelphia, and of a clade comprising Dasyuromorphia, Notoryctes,and Peramelemorphia, were supported strongly by both Bayesian posterior probabilities and maximum-likelihood bootstrap values. Monophyly of the Australasian marsupials, of Notoryctes þ Dasyuromorphia, and of Caenolestes þ Australidelphia were less well supported. Within Diprotodontia, Burramyidae þ Phalangeridae received relatively strong support. Divergence dates calculated using a Bayesian relaxed molecular clock and multiple age constraints suggested at least 3 independent dispersals of marsupials from North to South America during the Late Cretaceous or early Paleocene. Within the Australasian clade, the macropodine radiation, the divergence of phascogaline and dasyurine dasyurids, and the divergence of perameline and peroryctine peramelemorphians all coincided with periods of significant environmental change during the Miocene. An analysis of ‘‘unrepresented basal branch lengths’’ suggests that the fossil record is particularly poor for didelphids and most groups within the Australasian radiation.

  • A Phylogeny and Timescale for Marsupial Evolution Based on Sequences for Five Nuclear Genes
    J Mammal Evol DOI 10.1007/s10914-007-9062-6 ORIGINAL PAPER A Phylogeny and Timescale for Marsupial Evolution Based on Sequences for Five Nuclear Genes Robert W. Meredith & Michael Westerman & Judd A. Case & Mark S. Springer # Springer Science + Business Media, LLC 2007 Abstract Even though marsupials are taxonomically less diverse than placentals, they exhibit comparable morphological and ecological diversity. However, much of their fossil record is thought to be missing, particularly for the Australasian groups. The more than 330 living species of marsupials are grouped into three American (Didelphimorphia, Microbiotheria, and Paucituberculata) and four Australasian (Dasyuromorphia, Diprotodontia, Notoryctemorphia, and Peramelemorphia) orders. Interordinal relationships have been investigated using a wide range of methods that have often yielded contradictory results. Much of the controversy has focused on the placement of Dromiciops gliroides (Microbiotheria). Studies either support a sister-taxon relationship to a monophyletic Australasian clade or a nested position within the Australasian radiation. Familial relationships within the Diprotodontia have also proved difficult to resolve. Here, we examine higher-level marsupial relationships using a nuclear multigene molecular data set representing all living orders. Protein-coding portions of ApoB, BRCA1, IRBP, Rag1, and vWF were analyzed using maximum parsimony, maximum likelihood, and Bayesian methods. Two different Bayesian relaxed molecular clock methods were employed to construct a timescale for marsupial evolution and estimate the unrepresented basal branch length (UBBL). Maximum likelihood and Bayesian results suggest that the root of the marsupial tree is between Didelphimorphia and all other marsupials. All methods provide strong support for the monophyly of Australidelphia. Within Australidelphia, Dromiciops is the sister-taxon to a monophyletic Australasian clade.

  • New Large Leptictid Insectivore from the Late Paleogene of South Dakota, USA
    New large leptictid insectivore from the Late Paleogene of South Dakota, USA TJ MEEHAN and LARRY D. MARTIN Meehan, T.J. and Martin, L.D. 2012. New large leptictid insectivore from the Late Paleogene of South Dakota, USA. Acta Palaeontologica Polonica 57 (3): 509–518. From a skull and mandible, we describe a new genus and species of a primitive insectivore (Mammalia: Insectivora: Leptictida: Leptictidae). Its large body size and higher−crowned teeth indicate a different feeding ecology from other leptictid insectivores. With evidence of some heavy, flat wear on the molariform teeth, its shift in diet was likely to greater herbivory. Unlike the narrow snout of Blacktops, this new leptictid retains a broad snout, suggesting that small verte− brates were still important dietary components. The specimen was collected from the floodplain deposits of the lower or middle White River Group of South Dakota, which represent the latest Eocene to earliest Oligocene (Chadronian and Orellan North American Land Mammal “Ages”).

The lack of an identifiable intermediate host species for the proximal animal ​ ancestor of SARS-CoV-2 and the distance (~1500 km) from Wuhan to Yunnan province, where the closest evolutionary related coronaviruses circulating in horseshoe bats have been identified, is fueling speculation on the natural origins of SARS-CoV-2.

  • Appendix Lagomorph Species: Geographical Distribution and Conservation Status
    Appendix Lagomorph Species: Geographical Distribution and Conservation Status PAULO C. ALVES1* AND KLAUS HACKLÄNDER2 Lagomorph taxonomy is traditionally controversy, and as a consequence the number of species varies according to different publications. Although this can be due to the conservative characteristic of some morphological and genetic traits, like general shape and number of chromosomes, the scarce knowledge on several species is probably the main reason for this controversy. Also, some species have been discovered only recently, and from others we miss any information since they have been first described (mainly in pikas). We struggled with this difficulty during the work on this book, and decide to include a list of lagomorph species (Table 1). As a reference, we used the recent list published by Hoffmann and Smith (2005) in the “Mammals of the world” (Wilson and Reeder, 2005). However, to make an updated list, we include some significant published data (Friedmann and Daly 2004) and the contribu- tions and comments of some lagomorph specialist, namely Andrew Smith, John Litvaitis, Terrence Robinson, Andrew Smith, Franz Suchentrunk, and from the Mexican lagomorph association, AMCELA. We also include sum- mary information about the geographical range of all species and the current IUCN conservation status. Inevitably, this list still contains some incorrect information. However, a permanently updated lagomorph list will be pro- vided via the World Lagomorph Society (www.worldlagomorphsociety.org). 1 CIBIO, Centro de Investigaça˜o em Biodiversidade e Recursos Genéticos and Faculdade de Ciˆencias, Universidade do Porto, Campus Agrário de Vaira˜o 4485-661 – Vaira˜o, Portugal 2 Institute of Wildlife Biology and Game Management, University of Natural Resources and Applied Life Sciences, Gregor-Mendel-Str.
