We com- pared 24 h return rates of newly toe-tipped frogs to those previously toe-tipped and found no evi- dence of a stress response reflected by avoidance behaviour for 3 species: Litoria genimaculata, L. rheocola and Nyctimystes dayi. L. nannotis was the only studied species to demonstrate a greater reaction to toe-tipping than handling alone; however, return rates (65%) in the 1 to 3 mo after mark- ing were the highest of any species, showing that the reaction did not endure. The comparatively milder short-term response to toe-tipping in N. dayi (24% return rate) may have been caused by the species’ reduced opportunity for breeding. Intermediate-term return rates were relatively high for 2 species, L. nannotis and L. genimaculata, given their natural history, suggesting there were no major adverse effects of toe-tipping. Longer-term adverse effects could not be ruled out for L. -

Southern Brown Tree Frog
Our Wildlife Fact Sheet Southern Brown Tree Frog Southern Brown Tree Frogs are one of Victoria’s common frog species. Scientific name Litoria ewingi Did you know? The Southern Brown Tree Frog is an agile hunter. It can leap to catch insects in mid flight. Their large sticky toes make them great climbers. Figure 1. Southern Brown Tree Frog metamorphs © A. Houston Female Southern Brown Tree Frogs can lay up to 600 DSE 2008 eggs at a time. Distribution It takes between 12 and 26 weeks for Southern Brown Southern Brown Tree Frogs occur in southern Victoria, tadpoles to turn into frogs. Tasmania and along the south coast of New South Wales. Description They are found across most of southern, central and Southern Brown Tree Frogs grow up to about 50 mm in north-eastern Victoria, but do not occur in the north- length. west corner of the state. In north-central Victoria and in Their colour is true to their name as they are brown on parts of the state’s north-east they are replaced by the their backs. The backs of their thighs are yellowish to closely-related Plains Brown Tree Frog (Litoria bright orange, and they have a white grainy belly. They paraewingi). also have a distinctive white stripe from the eye to their fore-leg. Their skin is smooth with small lumps. They have webbing on their feet that goes half way up their toes while their fingers have no webbing at all. Breeding males have a light brown vocal sac. Diet Southern Brown Tree Frogs feed mainly on flying insects such as mosquitoes, moths and flies. -
Conservation Advice Litoria Dayi Lace-Eyed Tree Frog
THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister’s delegate approved this Conservation Advice on 13/07/2017. Conservation Advice Litoria dayi lace-eyed tree frog Conservation Status Litoria dayi (lace-eyed tree frog) is listed as Endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) effective 16 July 2000. The species is eligible for listing under the EPBC Act as on 16 July 2000 it was listed as Endangered under Schedule 1 of the preceding Act, the Endangered Species Protection Act 1992 (Cwlth). Species can also be listed as threatened under state and territory legislation. For information on the current listing status of this species under relevant state or territory legislation, see http://www.environment.gov.au/cgi-bin/sprat/public/sprat.pl . The main factor that was the cause of the species being eligible for listing in the Endangered category was a dramatic range contraction with an observed reduction in population size of greater than 50 percent. Populations are no longer present at altitudes greater than 300 m, likely due to chytridiomycosis (Hero et al. 2004). This species’ status under the EBPC Act is currently being reviewed as part of a species expert assessment plan for frogs. Description The lace-eyed tree frog was recently transferred to the genus Litoria from the genus Nyctimystes after Kraus (2013) showed that it did not meet the morphological characteristics for assignment to that genus (Cogger 2014). This species is a small to medium sized frog growing to 50 mm in snout-to-vent length. -

Aircraft and maritime vessels entered Guam from Australia, the home range of the species (Cogger, 2000) during the late 1960s, although documentation with respect to the frequency of these arrivals and the types of commodities shipped is difficult to obtain. It is therefore unclear whether the Guam population is the result of released pets, stowaways onboard a transport vessel, or stowaways in suitable cargo such as fruit or vegetables.” Remarks From GBIF (2016): “BASIONYM Hylomantis fallax Peters, 1880” 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing From ITIS (2017): “Kingdom Animalia Subkingdom Bilateria Infrakingdom Deuterostomia Phylum Chordata Subphylum Vertebrata Infraphylum Gnathostomata Superclass Tetrapoda Class Amphibia Order Anura Family Hylidae Subfamily Pelodryadinae Genus Litoria Species Litoria fallax (Peters, 1880)” “Current Standing: valid” Size, Weight, and Age Range From Atlas of Living Australia (2017): “Up to less than 30mm” 2 Environment From Hero et al. -
Toadally Frogs Frog Wranglers
Toadally Frogs Frog Wranglers P rogram Theme: • Frogs are toadally awesome! P rogram Messages: • Frogs are remarkable creatures • A frogs ability to adapt to its environment is evident in it physiology • Frogs are extremely sensitive to their surroundings and as a result are considered to be an indicator species P rogram Objectives: • Gallery Participants will observe live frogs face-to-face • Gallery Participants will be able to describe several physical features and unique qualities of the White’s tree frog • Gallery Participants will get excited about frogs Frog Wrangling Procedure 1. Wash and dry your hands. You may use regular tap water and light soap, but insure that you rinse your hands thoroughly. 2. Move frog from the Public Programs suite into carrying case. Whenever you transport your frog from the Public Programs suite to the exhibit, please carefully remove them from the habitat terrarium and place them in the small red carrying case (cooler). This will prevent the animal from becoming stressed as it is moved through the Museum. 3. Prepare your audience. Prior to bring out the live frog, ensure that everyone is seated and that you have asked your audience not to move quickly. Sit on the floor as well; this will ensure that if the frog leaps from your hands, it would not have far to fall. 4. Wet your hands. When you are ready to show the frog as part of your demonstration, please moisten your hands with the spray bottle. This will help minimize your dry skin from sucking the moisture out of the frog. -
Report on the Large Brown Tree Frog By
Qualifications and Experience Please see my curriculum vitae (Appendix I) for my general qualifications and experience. My Ph.D. in zoology focussed specifically on the conservation biology and ecology of frog species in south-eastern Australia. I have 23 years of field and scientific experience studying amphibians and their conservation and management in south-eastern Australia. I have published 24 refereed scientific papers and 38 technical reports on amphibian ecology, conservation and management. I am recognised throughout Australia as an authority on the frog fauna of Victoria, specifically with respect to conservation issues, and I am regularly asked to provide advice on such matters to individuals, government conservation and land management agencies, and non-government organisations. With regard to the Large Brown Tree Frog, I encountered this species on numerous occasions between 1986 and 1992 while undertaking and supervising pre-logging biodiversity surveys in East Gippsland, Victoria. Many of these records are documented in the Victorian Wildlife Atlas. During this period, I gained knowledge of the species’ habitat associations, breeding biology, some aspects of its behaviour and an appreciation of its conservation status in Victoria (see Opie et al. 1990; Westaway et al.1990; Lobert et al. 1991). Because of my research into amphibian conservation and management, I am highly familiar with the existing literature on the impact of various forest management activities on amphibians and the implications of these activities for amphibian conservation. Although no specific studies have investigated the effects of forest management on the Large Brown Tree Frog, this general knowledge provides insight into the potential impacts of forest management on this species. -
Ecology of Pyrmont Peninsula 1788 - 2008
Transformations: Ecology of Pyrmont peninsula 1788 - 2008 John Broadbent Transformations: Ecology of Pyrmont peninsula 1788 - 2008 John Broadbent Sydney, 2010. Ecology of Pyrmont peninsula iii Executive summary City Council’s ‘Sustainable Sydney 2030’ initiative ‘is a vision for the sustainable development of the City for the next 20 years and beyond’. It has a largely anthropocentric basis, that is ‘viewing and interpreting everything in terms of human experience and values’(Macquarie Dictionary, 2005). The perspective taken here is that Council’s initiative, vital though it is, should be underpinned by an ecocentric ethic to succeed. This latter was defined by Aldo Leopold in 1949, 60 years ago, as ‘a philosophy that recognizes[sic] that the ecosphere, rather than any individual organism[notably humans] is the source and support of all life and as such advises a holistic and eco-centric approach to government, industry, and individual’(http://dictionary.babylon.com). Some relevant considerations are set out in Part 1: General Introduction. In this report, Pyrmont peninsula - that is the communities of Pyrmont and Ultimo – is considered as a microcosm of the City of Sydney, indeed of urban areas globally. An extensive series of early views of the peninsula are presented to help the reader better visualise this place as it was early in European settlement (Part 2: Early views of Pyrmont peninsula). The physical geography of Pyrmont peninsula has been transformed since European settlement, and Part 3: Physical geography of Pyrmont peninsula describes the geology, soils, topography, shoreline and drainage as they would most likely have appeared to the first Europeans to set foot there. -
The Critically Endangered Species Litoria Spenceri Demonstrates
Official journal website: Amphibian & Reptile Conservation amphibian-reptile-conservation.org 12(2) [Special Section]: 28–36 (e166). The critically endangered species Litoria spenceri demonstrates subpopulation karyotype diversity 1,2,7Richard Mollard, 3Michael Mahony, 4Gerry Marantelli, and 5,6Matt West 1Faculty of Veterinary and Agricultural Sciences, University of Melbourne, Parkville, 3052, Victoria, AUSTRALIA 2Amphicell Pty Ltd, Cairns, Queensland, AUSTRALIA 3School of Environmental and Life Sciences, The University of Newcastle, 2308 New South Wales, AUSTRALIA 4The Amphibian Research Centre, PO Box 1365, Pearcedale, Victoria, 3912, AUSTRALIA 5School of BioSciences, University of Melbourne, 3010 Victoria, AUSTRALIA 6National Environmental Science Program, Threatened Species Recovery Hub, The University of Queensland, St Lucia, QLD 4072, AUSTRALIA Abstract.—Litoria spenceri is a critically endangered frog species found in several population clusters within Victoria and New South Wales, Australia. Biobanking of cell cultures obtained from toe clippings of adults originating from Southern, Northern and Central Site locations, as well as Northern x Central Site hybrid tadpole crosses was performed. Analysis of biobanked cells demonstrates a 2n = 26 karyotype and chromosomal morphology characteristic of the Litoria genus. A potential nucleolar organiser region (NOR) on chromosome 9 demonstrates similar designation to L. pearsoniana and L. phyllochroa of the same phylogenetic subgroup. A second potential novel NOR was also located on the long arm of chromosome 11, and only within the Central Site population. This Central Site apparent NOR is inheritable to Northern x Central Site tadpole hybrids in the heterozygous state and appears to be associated with a metacentric to submetacentric morphological transformation of the Northern Site inherited matched chromosome of that pair.
