Diet of Feral Cats, Felis Catus, on Dirk Hartog Island
Journal of the Royal Society of Western Australia, 98: 37–43, 2015 Diet of feral cats, Felis catus, on Dirk Hartog Island M DELLER 1, H R MILLS 1*, N HAMILTON 2 & D ALGAR 2 1 School of Animal Biology, University of Western Australia, Crawley, WA, 6009, Australia. 2 Department of Parks and Wildlife, Science and Conservation Division, P.O. Box 51, Wanneroo, WA, 6946, Australia. * Corresponding author [email protected] ABSTRACT Ten mammal species of conservation priority have been lost from Dirk Hartog Island, off the coast of Western Australia, most likely due to predation by the feral cat. We examined the diet of fourteen feral cats from Dirk Hartog Island to understand the potential impact of cat predation on remaining extant species. We examined the contents of the stomach and large intestine, and used stable isotope analysis of faeces, liver and muscle. The vertebrate species identified in the digestive tracts included at least six bird species, including two terrestrial birds and four shorebirds, seven reptile species, and one mammal (introduced Mus musculus). Analysis of δ13C and δ15N determined that the diet of feral cats was primarily terrestrially derived, although samples from the northern area of Dirk Hartog Island showed a skew towards marine derived food sources. The research findings showed that on this island, in the absence of rabbits, cats preyed mainly on terrestrial birds and reptiles. KEYWORDS: Feral cat, diet, Dirk Hartog Island, stomach content and faecal analysis, stable isotopes INTRODUCTION is present on Dirk Hartog Island and, depending upon abundance, could contribute significantly to the feral Feral cats (Felis catus) are found on most major island cats’ diet. -
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. -

We trust you will enjoy reading Wildlife Matters, which we hope to fill with good news about the wildlife in AWC’s sanctuaries. Unfortunately, for most of the last 200 years the news regarding Australia’s wildlife has not been good. The Toolache Wallaby, widely regarded as the most beautiful and graceful member of the kangaroo family, is gone forever. The Thylacine, the Paradise Parrot and the enigmatic Lesser Bilby are just some of the other animals that Australia has lost. continued on page 2 CONTENTS Is Mt Zero the Last Chance for the Northern Bettong? 3 Northern Bettong Photo: QPWS Eastern Pebble-mound Mouse Wet Sclerophyll Forest Sanctuary News 4 ustralian Wildlife Conservancy is proposing to acquire a The Evolution of AWC 6 remarkable wilderness area in north Queensland that is AWC Provides New Hope Ahome to more than 35 native mammal species.

Bandicoot Fossils and DNA Elucidate Lineage Antiquity Amongst Xeric
www.nature.com/scientificreports OPEN Bandicoot fossils and DNA elucidate lineage antiquity amongst xeric-adapted Received: 31 May 2016 Accepted: 31 October 2016 Australasian marsupials Published: 24 November 2016 Benjamin P. Kear1,2, Ken P. Aplin3 & Michael Westerman4 Bandicoots (Peramelemorphia) are a unique order of Australasian marsupials whose sparse fossil record has been used as prima facie evidence for climate change coincident faunal turnover. In particular, the hypothesized replacement of ancient rainforest-dwelling extinct lineages by antecedents of xeric-tolerant extant taxa during the late Miocene (~10 Ma) has been advocated as a broader pattern evident amongst other marsupial clades. Problematically, however, this is in persistent conflict with DNA phylogenies. We therefore determine the pattern and timing of bandicoot evolution using the first combined morphological + DNA sequence dataset of Peramelemorphia. In addition, we document a remarkably archaic new fossil peramelemorphian taxon that inhabited a latest Quaternary mosaic savannah-riparian forest ecosystem on the Aru Islands of Eastern Indonesia. Our phylogenetic analyses reveal that unsuspected dental homoplasy and the detrimental effects of missing data collectively obscure stem bandicoot relationships. Nevertheless, recalibrated molecular clocks and multiple ancestral area optimizations unanimously infer an early diversification of modern xeric-adapted forms. These probably originated during the late Palaeogene (30–40 Ma) alongside progenitors of other desert marsupials, and thus occupied seasonally dry heterogenous habitats long before the onset of late Neogene aridity. Bandicoots (Peramelemorphia) are a speciose order of Australasian marsupials that appeared early in the evolu- tionary history of Australidelphia1. Most are small to medium sized (up to 5 kg) terrestrial omnivores occupying a spectrum of rainforest to desert habitats2,3. -

Extant taxa (18 species) are characteristically omnivorous, small to medium sized (0.1-4.9 kg) semi-fossorial/fossorial marsupials with a quadrupedal bounding gait. They occupy varied habitats from desert to rainforest in Australia and New Guinea. Fourteen pre-Pliocene taxa are currently described on the basis of cranial and/or dental material, yet none is known from its postcranial skeleton. Here we use qualitative morphological and morphometric data to analyse a partial skeleton of a new species of bandicoot from a middle Miocene cave deposit, AL90 Site, in the Riversleigh World Heritage Area.
