ABSTRACT Gut microbiota play an important role in maintenance of mammalian metabolism and immune system regulation, disturbances to this community can have adverse impacts on animal health. To better understand the composition gut marine mammals, fecal bacterial communities Australian sea lion ( Neophoca cinerea ), endangered pinniped with localized distribution, were examined. A comparison samples from individuals across 11 wild colonies South Western Australia three captive populations...
Greater interaction between humans and wildlife populations poses significant risks of anthropogenic impact to natural ecosystems, especially in the marine environment. Understanding spread microorganisms at interface is therefore important if we are mitigate adverse effects on wildlife. We investigated establishment Escherichia coli endangered Australian sea lion (Neophoca cinerea) by comparing fecal isolation from wild captive populations. Fecal samples were collected colonies March...
Giardia and Cryptosporidium are amongst the most common protozoan parasites identified as causing enteric disease in pinnipeds. A number of assemblages species genotypes humans terrestrial mammals have also been marine mammals. To investigate occurrence these an endangered mammal, Australian sea lion (Neophoca cinerea), genomic DNA was extracted from faecal samples collected wild populations (n = 271) Southern Western Australia three captive 19). These were screened using PCR targeting 18S...
Knowledge of how animals cope with their environment is fundamental to the management free-ranging populations. Urban face increased competition for resources, habitat fragmentation and predation. These pressures may impact an individual’s welfare by releasing glucocorticoid hormones in blood through a response from hypothalamic–pituitary–adrenal axis, resulting altered energy storage utilisation. This study aimed determine applicability measuring faecal metabolites bandicoots using simple...
Volunteer wildlife rehabilitators rescue and rehabilitate thousands of native animals every year in Australia. However, there is little known about how exposure to novel stimuli during rehabilitation could affect the physiology wildlife. We investigated this question a species that commonly enters rehabilitation, common brushtail possum (Trichosurus vulpecula). evaluated five enzyme immunoassays (EIA) determine most suitable for measuring faecal glucocorticoid metabolites (FGM) as proxy...
Urban environments support high concentrations of humans, domestic pets and introduced animals, creating conditions conducive to the transmission parasites. This study compared patterns ectoparasite infestation common brushtail possum Trichosurus vulpecula in urbanised Sydney (n = 161) those from a remote woodland site 18) February 2005 – November 2006. We found diff erences species prevalence between two groups: flea Echidnophaga myrmecobii was only on urban possums tick Ixodes trichosuri...
The physiological stress hormone levels and physical condition of captured urban flying-foxes experiencing a food shortage were compared with those free-living rural access to supplementary food. Glucocorticoid determined by measuring glucocorticoid metabolites (GCMs) from the faeces individual animals. in good high Body Condition Indexes (BCIs) low GCMs, range which may be considered baseline for this species. In comparison, had lower BCIs elevated GCMs: 75% that higher than 30% an order...
Although hopping is a relatively rare mammalian gait, mammals are common in arid environments. Arid environments open, with patchy resources, and the widespread use of by zone appears to be related benefits fast locomotion. In several species, economical comparison quadrupedal running. These species can reach greater maximum aerobic speeds than similarly sized runners. Faster locomotion reduce predation risk increase opportunities exploit open microhabitats. More may improve mammal's ability...
Summary We investigated the muscle structure/function relationships that underlie aerobic capacities of an insectivorous, small (~15 g) marsupial, Sminthopsis crassicaudata (Family: Dasyuridae). This was for further insight into energy use patterns in marsupials, relative to those placentals, their sister clade within Theria (advanced mammals). Disparate hopping marsupials (Suborder Macropodiformes), a kangaroo (Macropus rufus) and rat-kangaroo (Bettongia penicillata), show capabilities as...
Marsupials and placentals together comprise the Theria, advanced mammals, but they have had long independent evolutionary histories, with last common ancestor occurring more than 125 million years ago. Although in past marsupials were considered to be metabolically 'primitive', red kangaroo Macropus rufus has been reported an aerobic capacity (VO2max) comparable that of most 'athletic' such as dogs. However, kangaroos travel at moderate speeds lower relative cost quadrupedal placentals....
We examined the structure-function relationships that underlie aerobic capacities of marsupial mammals hop. Marsupials have relatively low basal metabolic rates (BMR) and historically were seen as 'low energy' mammals. However, red kangaroo, Macropus rufus (family Macropodidae), has equivalent to athletic placentals. It an extreme scope (fAS) its large locomotor muscles feature high mitochondrial capillary volumes. M. belongs a modern group kangaroos fAS is not general for marsupials. other...
