Red-Necked Wallaby (Bennett’S Wallaby) Macropus Rufogriseus
Red-necked Wallaby (Bennett’s Wallaby) Macropus rufogriseus Class: Mammalia Order: Diprotodontia Family: Macropodidae Characteristics: Red-necked wallabies get their name from the red fur on the back of their neck. They are also differentiated from other wallabies by the white cheek patches and larger size compared to other wallaby species (Bioweb). The red-necked wallaby’s body fur is grey to reddish in color with a white or pale grey belly. Their muzzle, paws and toes are black (Australia Zoo). Wallabies look like smaller kangaroos with their large hindquarters, short forelimbs, and long, muscular tails. The average size of this species is 27-32 inches in the body with a tail length of 20-28 inches. The females weigh about 25 pounds while the males weigh significantly more at 40 pounds. The females differ from the males of the species in that they have a forward opening pouch (Sacramento Zoo). Range & Habitat: Flat, high-ground eucalyptus Behavior: Red-necked wallabies are most active at dawn and dusk to avoid forests near open grassy areas in the mid-day heat. In the heat, they will lick their hands and forearms to Tasmania and South-eastern promote heat loss. (Animal Diversity) These wallabies are generally solitary Australia. but do forage in small groups. The males will have boxing matches with one another to determine social hierarchy within populations. They can often be seen punching, wrestling, skipping, dancing, standing upright, grabbing, sparring, pawing, and kicking. All members of the kangaroo and wallaby family travel by hopping. Red-necked wallabies can hop up to 6 feet in the air. -

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. -

A Species-Level Phylogenetic Supertree of Marsupials

P.

One solution is to combine algorithmically many small trees into a single, larger supertree. Here we present a virtually complete, species-level phylogeny of the marsupials (Mammalia: Metatheria), built by combining 158 phylogenetic estimates published since 1980, using matrix representation with parsimony. The supertree is well resolved overall (73.7%), although resolution varies across the tree, indicating variation both in the amount of phylogenetic information available for different taxa, and the degree of conflict among phylogenetic estimates. In particular, the supertree shows poor resolution within the American marsupial taxa, reflecting a relative lack of systematic effort compared to the Australasian taxa. There are also important differences in supertrees based on source phylogenies published before 1995 and those published more recently. The supertree can be viewed as a meta-analysis of marsupial phylogenetic studies, and should be useful as a framework for phylogenetically explicit comparative studies of marsupial evolution and ecology. -

REPRODUCTIONREVIEW Wombat reproduction (Marsupialia; Vombatidae): an update and future directions for the development of artificial breeding technology Lindsay A Hogan1, Tina Janssen2 and Stephen D Johnston1,2 1Wildlife Biology Unit, Faculty of Science, School of Agricultural and Food Sciences, The University of Queensland, Gatton 4343, Queensland, Australia and 2Australian Animals Care and Education, Mt Larcom 4695, Queensland, Australia Correspondence should be addressed to L A Hogan; Email: [email protected] Abstract This review provides an update on what is currently known about wombat reproductive biology and reports on attempts made to manipulate and/or enhance wombat reproduction as part of the development of artificial reproductive technology (ART) in this taxon. Over the last decade, the logistical difficulties associated with monitoring a nocturnal and semi-fossorial species have largely been overcome, enabling new features of wombat physiology and behaviour to be elucidated. Despite this progress, captive propagation rates are still poor and there are areas of wombat reproductive biology that still require attention, e.g. further characterisation of the oestrous cycle and oestrus. Numerous advances in the use of ART have also been recently developed in the Vombatidae but despite this research, practical methods of manipulating wombat reproduction for the purposes of obtaining research material or for artificial breeding are not yet available. Improvement of the propagation, genetic diversity and management of wombat populations requires a thorough understanding of Vombatidae reproduction. While semen collection and cryopreservation in wombats is fairly straightforward there is currently an inability to detect, induce or synchronise oestrus/ovulation and this is an impeding progress in the development of artificial insemination in this taxon. -

Cercartetus Lepidus (Diprotodontia: Burramyidae)
MAMMALIAN SPECIES 842:1–8 Cercartetus lepidus (Diprotodontia: Burramyidae) JAMIE M. HARRIS School of Environmental Science and Management, Southern Cross University, Lismore, New South Wales, 2480, Australia; [email protected] Abstract: Cercartetus lepidus (Thomas, 1888) is a burramyid commonly called the little pygmy-possum. It is 1 of 4 species in the genus Cercartetus, which together with Burramys parvus form the marsupial family Burramyidae. This Lilliputian possum has a disjunct distribution, occurring on mainland Australia, Kangaroo Island, and in Tasmania. Mallee and heath communities are occupied in Victoria and South Australia, but in Tasmania it is found mainly in dry and wet sclerophyll forests. It is known from at least 18 fossil sites and the distribution of these reveal a significant contraction in geographic range since the late Pleistocene. Currently, this species is not listed as threatened in any state jurisdictions in Australia, but monitoring is required in order to more accurately define its conservation status. DOI: 10.1644/842.1.

A New Family of Diprotodontian Marsupials from the Latest Oligocene of Australia and the Evolution of Wombats, Koalas, and Their Relatives (Vombatiformes) Robin M
www.nature.com/scientificreports OPEN A new family of diprotodontian marsupials from the latest Oligocene of Australia and the evolution of wombats, koalas, and their relatives (Vombatiformes) Robin M. D. Beck1,2 ✉ , Julien Louys3, Philippa Brewer4, Michael Archer2, Karen H. Black2 & Richard H. Tedford5,6 We describe the partial cranium and skeleton of a new diprotodontian marsupial from the late Oligocene (~26–25 Ma) Namba Formation of South Australia. This is one of the oldest Australian marsupial fossils known from an associated skeleton and it reveals previously unsuspected morphological diversity within Vombatiformes, the clade that includes wombats (Vombatidae), koalas (Phascolarctidae) and several extinct families. Several aspects of the skull and teeth of the new taxon, which we refer to a new family, are intermediate between members of the fossil family Wynyardiidae and wombats. Its postcranial skeleton exhibits features associated with scratch-digging, but it is unlikely to have been a true burrower. Body mass estimates based on postcranial dimensions range between 143 and 171 kg, suggesting that it was ~5 times larger than living wombats. Phylogenetic analysis based on 79 craniodental and 20 postcranial characters places the new taxon as sister to vombatids, with which it forms the superfamily Vombatoidea as defned here. It suggests that the highly derived vombatids evolved from wynyardiid-like ancestors, and that scratch-digging adaptations evolved in vombatoids prior to the appearance of the ever-growing (hypselodont) molars that are a characteristic feature of all post-Miocene vombatids. Ancestral state reconstructions on our preferred phylogeny suggest that bunolophodont molars are plesiomorphic for vombatiforms, with full lophodonty (characteristic of diprotodontoids) evolving from a selenodont morphology that was retained by phascolarctids and ilariids, and wynyardiids and vombatoids retaining an intermediate selenolophodont condition.
