...’ or ‘Australian’ appeared in the title. For documents not included in the Top 50 we determined length, number of authors, OA availability, whether there were international authors, and whether the words ‘Australia’ or ‘Australian’ appeared in the title. We also calculated mean FWCI for all documents in 2000, 2005...

... and understorey) but Greater Gliders were still present on all six transects burnt at low to moderate severity (44–77% of eucalypt foliage killed), although in significantly lower numbers (mean decline of 43% per transect). Greater Gliders feed on eucalypt leaves and their post-fire survival appears...

... wildfires and one year of exceptionally high rainfall. The number of frogs detected per year ranged from 23 to 109, with the lowest number found in 2020, some eight months after a wildfire burnt all sites. Comparisons of the mean number of frogs detected among years revealed the population took 13 years...

..., mean abundance of P. v. minor was 0.24 ha-1 in wet sclerophyll and 0.38 ha-1 in dry sclerophyll forest. Field observations (n= 330) were collected from nine radio-collared animals across three field sites from July to October 2019. 95% kernel home range estimates varied, ranging from 1.03 – 11.45 ha...

... photobleaching in two minutes of direct sun exposure, or a few hours when exposed to indoor lighting. The fleeting nature of porphyrins means that an accurate representation of pink-orange-red photoluminescence should not be expected in specimens that have been exposed to light, whether in life, post-mortem...

... of predators (domestic cats and foxes) at all sites. Rats rapidly investigated the log piles (mean time to first rat observation ± SE: 27.25 ± 14.34 days), but were only recorded intermittently over the monitoring period, suggesting that they did not permanently inhabit the sites. Our results suggest...

... flight duration data), despite the mean number of flights undertaken decreasing from 5.7 pre-spray to 4.7 post-spray during 10 min survey periods. The proportion of display flights in which the male was calling, however, did not differ between pesticide-exposed and unexposed male C. cruralis (χ 2 (0.05...

..., this individual has since become known as “Migaloo”, which is a First Nations meaning for “white fella”. In this short note we present the first extensive sighting history of Migaloo collected via scientific and citizen science efforts. This provides evidence of Migaloo’s presence in both Australian and New...

...Allen Greer; Sarah Smith In the small Australian dragon (agamid) lizard Tympanocryptis tetraporophora mean snout-vent length (SVL) does not differ significantly between the sexes within the species as a whole. However, in a large sample from Sturt National Park, in northwestern New South Wales...

... ° South. Forty seven V. vulturnus (24 females and 23 males) were captured in harp traps set in five different vegetation formations. Bats were captured in riverine woodland near water and in woodland to open forest habitats well away horn water. The mean forearm length of 19 males (24.7 mm...

... the exploitative developers, and reveals the lie that conserving nature is anti-wealth. Old thinking prevails to tragic results. Respect for the natural environment is a fundamental principle of humanity. Seeing things with fresh eyes is a challenge, and for conservation, that means challenging such assumptions...

... to extreme heat events and undertaking scientific research. The diversity of threats affecting the Grey-headed Flying-fox means that the species’ conservation is beyond the capacity of any one organisation and relies on the collaborative efforts of a broad range of stakeholders across the entire species...

.... A transition towards non-lethal means of protecting horticultural crops from flying-fox damage was supported by government programs that encouraged the uptake of exclusion netting in orchards. Cull limits and restrictions on licences to shoot flying-foxes on horticultural land were steps to the phasing out...

... with vehicles travelling consistent routes over long distances in rural areas: 59 vehicles fitted with ShuRoos and 40 vehicles without ShuRooss to act as controls. Drivers kept a log of collisions with macropods over an average distance travelled of 46,131 km. The overall mean rate of collisions with macropods...

... Zoologist were Australian-based, but there were still 10 or more authors from each of thirty-four other countries citing Australian Zoologist : while regional, the journal has an international profile. Highly cited papers in Australian Zoologist had high mean Scopus percentile ranks (20th century 83.9, 21st...

...Michael Bamford; Michael Calver “Habitat” is often used ambiguously in conservation biology and ecology to mean either the specific biotic and abiotic parts of the environment where an organism lives (e.g., the habitat of species x), or to describe a particular environment without reference...

... at which the species was detected were characterised by a mean annual precipitation of ≯1000mm, a mean annual temperature of <10 O C and altitudes <1000m. The presence of M. fuscus could not be confirmed at sites at lower elevations. Only populations in the Snowy Mountains region, specifically those...
