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. -

78 PRESIDENTIAL ADDRESS "AUSTRALIA AND HER NAVIGATORS" [By the President, COMMANDER NORMAN S. PIXLEY, C.M.G., M.B.E., V.R.D., Kt.O.N., F.R.Hist.S.Q.] (Read at a Meeting of the Society on 24 September 1970.) Joseph Conrad in his writings, refers to "The mysteriously born traditions of seacraft, command, and unity in an occu pation in which men's lives depend on each other." Still true today, how much more was this so with the mariners of long ago, who sailed in smaU ships for thousands of lonely leagues through unknown seas, for on them alone rested the safety of the ship and all on board. Dr. Johnson wrote "No man will be a saUor who has con trivance to get himself into jaU, for being in a ship is being in a jail with the chance of being drowned." There was more than an element of truth in this, for the seaman who refused to sail could be clapped in jail; whUst THE PRESIDENT, COMMANDER NORMAN S PIXLEY 79 those who did sail faced months in a confined space with acute discomfort, severe punishment at times, and provisions and water which deteriorated as the voyage proceeded. Scurvy kiUed more than storm and shipwreck until James Cook in his first voyage proved that it could be prevented. Clothing was rarely changed, the sailor coming wet to his hammock from his watch on deck in bad weather. Rats and cockroaches lived and thrived amongst the pro visions, adding to the problems of hygiene and health. -

Box 51, Wanneroo, Western Australia 6946, Australia. <[email protected]>. 2Department of Sustainability and Environment, Arthur Rylah Institute for Environmental Research, P.O. Box 137, Heidelberg, Victoria 3084, Australia. Abstract Feral cat eradication is planned for Dirk Hartog Island (620 km2), which is the largest island off the Western Australian coast. The island, in the Shark Bay World Heritage Property, once supported at least 13 species of native mammals but only three species remain. Since the 1860s, Dirk Hartog Island has been managed as a pastoral lease grazed by sheep and goats. Cats were probably introduced by early pastoralists and became feral during the late 19th century. Dirk Hartog Island was established as a National Park in November 2009, which provides the opportunity to eradicate feral cats and reconstruct the native mammal fauna. A 250 km2 pilot study was conducted on the island to assess the efficacy of aerial baiting as the primary technique for the eradication campaign. Initially, cats were trapped and fitted with GPS data-logger radio-collars. The collars were to provide information on daily activity patterns, to determine detection probabilities, and to optimise the proposed spacing of aerial baiting transects and the monitoring track network for the eradication. -

A Brief History of Wine in South Africa Stefan K
European Review - Fall 2014 (in press) A brief history of wine in South Africa Stefan K. Estreicher Texas Tech University, Lubbock, TX 79409-1051, USA Vitis vinifera was first planted in South Africa by the Dutchman Jan van Riebeeck in 1655. The first wine farms, in which the French Huguenots participated – were land grants given by another Dutchman, Simon Van der Stel. He also established (for himself) the Constantia estate. The Constantia wine later became one of the most celebrated wines in the world. The decline of the South African wine industry in the late 1800’s was caused by the combination of natural disasters (mildew, phylloxera) and the consequences of wars and political events in Europe. Despite the reorganization imposed by the KWV cooperative, recovery was slow because of the embargo against the Apartheid regime. Since the 1990s, a large number of new wineries – often, small family operations – have been created. South African wines are now available in many markets. Some of these wines can compete with the best in the world. Stefan K. Estreicher received his PhD in Physics from the University of Zürich. He is currently Paul Whitfield Horn Professor in the Physics Department at Texas Tech University. His biography can be found at http://jupiter.phys.ttu.edu/stefanke. One of his hobbies is the history of wine. He published ‘A Brief History of Wine in Spain’ (European Review 21 (2), 209-239, 2013) and ‘Wine, from Neolithic Times to the 21st Century’ (Algora, New York, 2006). The earliest evidence of wine on the African continent comes from Abydos in Southern Egypt. -

100 the SOUTH-WEST CORNER of QUEENSLAND. (By S
100 THE SOUTH-WEST CORNER OF QUEENSLAND. (By S. E. PEARSON). (Read at a meeting of the Historical Society of Queensland, August 27, 1937). On a clear day, looking westward across the channels of the Mulligan River from the gravelly tableland behind Annandale Homestead, in south western Queensland, one may discern a long low line of drift-top sandhills. Round more than half the skyline the rim of earth may be likened to the ocean. There is no break in any part of the horizon; not a landmark, not a tree. Should anyone chance to stand on those gravelly rises when the sun was peeping above the eastem skyline they would witness a scene that would carry the mind at once to the far-flung horizons of the Sahara. In the sunrise that western region is overhung by rose-tinted haze, and in the valleys lie the purple shadows that are peculiar to the waste places of the earth. Those naked, drift- top sanddunes beyond the Mulligan mark the limit of human occupation. Washed crimson by the rising sun they are set Kke gleaming fangs in the desert's jaws. The Explorers. The first white men to penetrate that line of sand- dunes, in south-western Queensland, were Captain Charles Sturt and his party, in September, 1845. They had crossed the stony country that lies between the Cooper and the Diamantina—afterwards known as Sturt's Stony Desert; and afterwards, by the way, occupied in 1880, as fair cattle-grazing country, by the Broad brothers of Sydney (Andrew and James) under the run name of Goyder's Lagoon—and the ex plorers actually crossed the latter watercourse with out knowing it to be a river, for in that vicinity Sturt describes it as "a great earthy plain." For forty miles one meets with black, sundried soil and dismal wilted polygonum bushes in a dry season, and forty miles of hock-deep mud, water, and flowering swamp-plants in a wet one. -

Photo - Richard Manning Return to 1616 – Ecological Restoration Project Dirk Hartog Island is Western Australia’s largest island. When visited by Dirk Hartog in 1616, the island was in pristine condition with a rich mammal fauna and flourishing vegetation. Since this first European landing on Australian soil, introduced plants and animals have degraded the island causing the local extinction of native species. Return to 1616 is an ambitious project helping to restore the island’s natural ecosystems. Introduced sheep and goats have been removed because their grazing and trampling damages native plants and reduces the food and shelter available for native animals. Feral cats are efficient hunters and have been eradicated from the island to make it safe for native animal species that are gradually being returned. These are the Shark Bay bandicoot, dibbler, chuditch, brush-tailed mulgara, greater stick-nest rat, desert mouse, Shark Bay mouse, heath mouse, woylie, boodie and western grasswren. In addition, rufous and banded hare-wallabies, have been included to improve their long-term survival. These animals are in need of conservation protection. Some are threatened and others extinct on the mainland. To find out more about the project, visit www.
