Abstract:
Nineteen species of rodents, in two families, have been recorded from Victoria in the modern era. Eighteen are of the family Muridae, represented by 15 native and 3 introduced species. The other species, now extinct in Victoria, was the introduced Sciurus carolinensis. Six of the native species are extinct, one is classified Critically Endangered, one Endangered and four Lower Risk – near threatened. Four of the extinct species were restricted to the semi-arid far north-west; these were Leporillus apicalis, L. conditor, Pseudomys bolami and P. desertor. The two other extinct species, Conilurus albipes and Pseudomys australis, inhabited open forest/woodland, and grassy ecosystems. Extant species include Rattus fuscipes and R. lutreolus, both in the sub-family Murinae; both are widespread and common, particularly in southern Victoria. The remaining seven species are in the sub-family Hydromyinae. Hydromys chrysogaster is widespread in waterbodies throughout the state. Notomys mitchellii and Pseudomys apodemoides occur in dry habitats in the north-west of Victoria; they are uncommon, but most of their habitat is reserved. Mastacomys fuscus, found in higher-rainfall areas of southern and eastern Victoria, from coastal dunes to alpine snowfields, is uncommon. The distribution of Pseudomys fumeus is disjunct, in four widely separated areas. It is classified as Endangered. P. shortridgei is restricted to the Grampians and south-western Victoria, where it may be locally common. The most geographically restricted rodent species in Victoria, Pseudomys novaehollandiae, is Critically Endangered and is the subject of special conservation measures. The most critical threats to rodent populations in Victoria are considered to be (1) the lack of active habitat management for those species that require early seral stages in vegetation, (2) predation by introduced carnivores, and (3) the fragmentation of species into small genetically isolated populations.

Abstract:
Grasslands are among the most endangered ecosystems, with <1% of Victorian grasslands remaining. Extinctions of many grassland fauna species have occurred since European settlement due to loss of suitable habitat, and dramatic range reductions continue for those that still exist. Fat-tailed dunnarts (Sminthopsis crassicaudata) are the only small ground-dwelling marsupial known to persist in Victorian grassland habitats. The last long-term targeted surveys for this species were conducted in Victoria in the 1970s. Incidental findings from more recent short-term targeted and non-targeted surveys in the same area suggest a decline. We performed direct targeted surveys for fat-tailed dunnarts at the 1970s survey site over a 12-month period in 2019 and found no evidence of fat-tailed dunnart presence. The species is classified as Near Threatened in the state and Least Concern internationally. Our work highlights the importance of targeted surveys to assess the stability of this species across Victoria, and the need for collection of long-term data to better identify population declines.

Abstract:
This study investigated the catch estimates, mortality, growth, food and feeding habits, and water parameters of Oreochromis variabilis in Upper Victoria Nile (UVN) from 2008 to 2019. Catch rates ranged 0.32±0.08 to 3.42±1.13 kg, boat-1, day-1 with the length-weight relationship indicating Isometric growth. Growth parameters obtained were L∞=36.75, K=0.44 yr-1, t0=-0.4540, tmax=6.4years, ØL=2.774, ØW=-0.301. Total mortality (Z) was 1.74yr-1, natural mortality (M) =0.95yr-1 using riverine surface temperature (RST) of 26oC giving a fishing mortality F of 0.79 yr-1 and exploitation ratio (E) of 0.4504 showing that growth parameters concurs with annual estimates and yield (F=6.589; P±=0.05). Catch estimates correlated with water parameters that indicated a significant difference. Mortality parameters showed that the fishery could be experiencing exploitation pressure. Although growth rates revealed that the fish is a long-lived species, if managed properly, its population could recover. Therefore, culturing the species and restocking in rivers and lakes in which this specie was not observed in the East African region are recommended.

Abstract:
Abstract We present a thorough redescription of the endangered freshwater crayfish Euastacus diversus Riek, based on morphological and genetic analyses of newly collected material from eastern Victoria, Australia. The species displays a remarkably diverse morphology, particularly regarding the two key features previously used in its diagnosis: spination of the antennal squame and thorax. Genetic variation is also evident between populations, although this does not correlate with morphological variation. The distribution of the species is extended to 19 sites in the Brodribb, Yalmy, Rodger and Bonang River drainages at elevations ranging from 350 – 950 m a.s.l., with an overall Extent of Occurrence of 465 km2. To accommodate the revised taxonomy of this species, and to facilitate conservation and management efforts, we provide a key to this and similar species in Victoria.

Abstract:
Abstract— Reinterpreting the morphology of two taxa proposed by Victoria C. Hollowell in the 1980s and not formally published, we describe here three new species of Eremitis, a Neotropical genus of herbaceous bamboos (Poaceae, Bambusoideae, Olyreae), which is endemic to the Brazilian Atlantic Forest. Two of them, Eremitis grandiflora and E. paucifolia, are endemic to Espírito Santo state. Eremitis victoriae occurs in southern Espírito Santo and has also been documented for southern Bahia. Eremitis grandiflora is similar to the smallest species of the genus, but can be differentiated by its decumbent culms with scale-like leaf blades and its longer gynecandrous whorls. Eremitis paucifolia is characterized by its leafy culms with a reduced number of leaves [5‐6(‐7)] compared to other species of the genus. Eremitis victoriae is distinguished from the congeneric species mainly by its abaxially glaucous leaf blades. Here, we provide an identification key to all described species of Eremitis that occur in Espírito Santo, as well as a map with their geographical distribution. All three new species are illustrated with both line drawings and photographic images, and an informal assessment of their conservation status is presented.

Abstract:
Labeo fisheri is an endemic and endangered freshwater fish of Sri Lanka. Mainly restricted to the upper reaches of the Mahaweli River basin, it has been previously reported living in deep rapids and among large rocks and boulders. An accidental record of a Labeo fisheri specimen from Victoria Reservoir led us to further study this habitat during the period from January to August 2017. This study was carried out to confirm the presence of a population of Labeo fisheri within the Victoria Reservoir and report its new habitat type in deep stagnant waters. We further investigated the food habits by analyzing the gut contents of L. fisheri in the Victoria Reservoir. Seven individuals were recorded from fishermen’s gill net catch in three fish landing sites along Victoria Reservoir, with an average total length of 24.80 ± 4.30 cm, average standard length of 19.70 ± 3.86 cm and average body weight of 197.69 ± 107.12 g. Based on gut content analysis, only phytoplankton, especially diatoms and cyanobacteria, were found in the gut of L. fisheri. This new population is facing the direct threat of fishing. Effective conservation measures are doubtful, since a fishery is well established in the Victoria Reservoir and the fishing gear used is not species-specific. More research is necessary to understand the population dynamics of L. fisheri in the Victoria Reservoir. In order to conserve it at this locality, community-based conservation measures are recommended.

"Ignoring the science in failing to conserve a faunal icon – major political, policy and management problems in preventing the extinction of Leadbeater’s possum." Pacific Conservation Biology 21, no. 4 (2015): 257. http://dx.doi.org/10.1071/pc15022.

Full text
Abstract:
Leadbeater’s possum (Gymnobelideus leadbeateri) is an arboreal marsupial that occurs primarily in the montane ash forests of the Central Highlands of Victoria. Leadbeater’s possum is among the best studied endangered species globally. Despite extensive monitoring and research, the ongoing population trajectory of the species has resulted in its recent upgrading from Endangered to Critically Endangered. One of the key processes threatening the species is the widespread use of clearfell logging, which significantly degrades the habitat of the species and results in long-term habitat loss, fragmented populations, and an elevated risk of high-severity crown-scorching fires. A general principle underpinning conservation biology is to remove key threatening processes to enhance the conservation of species. The cessation of clearfell logging and a major expansion of the reserve system are urgently needed to limit the risk of extinction of Leadbeater’s possum. Current government policies and practices that continue to result in clearfelling of montane ash forests run counter to the large body of science indicating what is needed to conserve Leadbeater’s possum. A large ecological reserve is urgently required to maximise the chances that the species will persist in the wild.

Full text
Abstract:
Many Australian rodent species have become extinct or undergone substantial range contractions since European invasion. Limited and haphazard survey efforts across much of Australia mean we are unsure of many species’ current and former ranges, hampering our ability to identify and remedy causes of decline. The New Holland Mouse (NHM; Pseudomys novaehollandiae) is an endangered rodent species native to south-east Australia that is suspected of undergoing rapid and dramatic range contractions and local extinctions in recent decades. Here, I reassess the species’ distribution across Victoria using extensive survey efforts and, subsequently, provide a summation of potential key threatening processes. In only 40 years, the NHM has been lost from seven of the 12 isolated areas where it once occurred in Victoria. Habitat loss and fragmentation, invasive predators, and potentially disease and genetic inbreeding have likely contributed to the species’ rapid and continuing decline. Conservation priorities include ongoing monitoring and research, cat and fox control, exclusion of rabbit poison-baiting, targeted fire and habitat management, and reintroduction to historically occupied regions where threatening processes have been mitigated.

Abstract:
We have identified the primary root fungal endophytes of Dipodium hamiltonianum F.M.Bailey, a species of orchid endangered in Victoria and uncommon in New South Wales and Queensland. Genomic DNA was extracted from whole colonised root portions from four orchid individuals and PCR amplified with ITS1F and ITS4 primers. Cloning and sequencing of the main amplicons produced from the PCR analysis revealed that the primary root fungal endophytes were Gymnomyces and Russula spp., both members of the Russulaceae. The implications of these findings are discussed in terms of conservation of the orchid species.

Full text
Abstract:
Assessment of the efficacy of survey techniques for determining species occurrence is crucial for the validation of wildlife survey data. We analysed repeated site-survey data for adults and larvae of the growling grass frog (Litoria raniformis) in order to estimate probabilities of detection for the species using alternative survey techniques. The estimated probability of detecting adults of L. raniformis at occupied sites using diurnal searches was much less than 1.0 (0.107; 95% credible interval: 0.045, 0.192). The estimated probability of detecting adults using nocturnal spotlight searches was considerably higher, but still less than 1.0 (0.696; 95% credible interval: 0.585, 0.796). These results indicate that nocturnal searches are a much more efficient and reliable means of detecting the presence of adult L. raniformis than diurnal searches, but detection using either technique is less than certain. The probability of detecting tadpoles of L. raniformis using either funnel-trapping or dip-netting techniques was estimated at 0.350 (95% credible interval: 0.151, 0.567). Together, these results indicate that reliance on single-site visits during surveys for this species is likely to result in severe under-estimation of the proportion of sites that are actually occupied. We urge other workers to use repeated site-survey data and appropriate methods of data analysis to assess and report probabilities of detection when documenting the results of wildlife surveys.

Abstract:
Forest Pattern and Ecological Process is a major synthesis of 25 years of intensive research about the montane ash forests of Victoria, which support the world's tallest flowering plants and several of Australia's most high profile threatened and/or endangered species. It draws together major insights based on over 170 published scientific papers and books, offering a previously unrecognised set of perspectives of how forests function. The book combines key strands of research on wildfires, biodiversity conservation, logging, conservation management, climate change and basic forest ecology and management. It is divided into seven sections: introduction and background; forest cover and the composition of the forest; the structure of the forest; animal occurrence; disturbance regimes; forest management; and overview and future directions. Illustrated with more than 200 photographs and line drawings, Forest Pattern and Ecological Process is an essential reference for forest researchers, resource managers, conservation and wildlife biologists, ornithologists and mammalogists, policy makers, as well as general readers with interests in wildlife and forests. 2010 Whitley Certificate of Commendation for Zoological Text.

Abstract:
Access to ‘all the world’s knowledge’ is an ancient aspiration; a less venerable, but equally vigorous, universalism strives for the borderless protection of authors’ rights. Late 19th-century law and politics brought us copyright universalism; 21st-century technology may bring us the universal digital library. But how can ‘all the world’s knowledge’ be delivered, on demand, to users anywhere in the world (with Internet access), if the copyrights of the creators and publishers of many of those works are supposed to be enforceable almost everywhere in the world? Does it follow that the universal digital library of the near future threatens copyright holders? Or are libraries the endangered species of the impending era, as publishers partner with for-profit Internet intermediaries to make books ubiquitously available? Does access-triumphalism therefore risk giving us not the universal digital library, but the universal digital bookstore? And, whether libraries or commercial intermediaries offer access, how will the world’s authors fare?
