...Harry F. Recher ABSTRACT Frequency of occurrence data are available for birds along a transect in Kings Park, Perth, Western Australia from 1928 to 2008. These data show a dynamic avifauna with about a third of the sixty-one bird species recorded declining in frequency since 1928, another third...

...Sacha Jellinek; Paula Peeters; Alice Henderson; Raymond J. Carpenter ABSTRACT The threatened Oenpelli rock python ( Nyctophilopython oenpelliensis ) is the third largest predator in the Arnhem Land region, and is known to occur in Kakadu National Park and Djelk and Warddeken Indigenous Protected...

... mid-March to mid-April (Autumn breeding) and early-August to mid-October (Spring breeding). Thirty-two percent of the 459 eggs laid during the study were laid in Autumn and 68% in Spring. Growth rates of nestling wings and body mass were similar between seasons and years. Nearly one third of breeding...

... and third funding rounds. Furthermore, only one grant was awarded for camp dispersal during the first funding round and none in subsequent funding rounds. Rather, the latter two funding rounds contained a greater representation of grants awarded for works aligned with biodiversity conservation objectives...

...Ian Abbott Information relating to the early decline of native mammal species in the western third of Australia, before the establishment of rabbits and foxes, was sought from recollections of oldtimers, archival records, historical documents, and searches of museum collections. Based...

... and this subsequently became the baseline for further population monitoring. A subset of 48 sites was resurveyed in 2010, and about one third of the sites (~40) were surveyed annually on a rotating panel between 2013–2019. Wildfire significantly impacted the Bago Plateau during 2020 and 51 sites were resurveyed post...

... the fires, two 1ha plots were established at the centre of each of the three owl territories. Assessments of these plots demonstrated that 22.6% of the large trees and stags were lost or severely damaged, with a third of this total being ≥100 cm dbh. Despite wide variation in the pre-fire canopy tree...

... that are in the database) was the most comprehensive. Although authors from 22 countries contributed papers over the history of the Australian Zoologist , over 90% of authors were Australian. Most international authors came from the USA, the UK, Canada and New Zealand. Approximately two-thirds of authors citing Australian...

... of birds to logging of a small, relatively isolated woodland remnant in a landscape dominated by agriculture, with a focus on declining woodland birds. Approximately two thirds of a 120 ha cypress-eucalypt woodland remnant was selectively logged. Eighty bird species in total were recorded 2–3½ years after...

... in New South Wales. Primarily, animals are balloted to licensed animal keepers and exhibitors. Otherwise, rehoming may be delegated to third party organisations, and pet shops licensed to sell reptiles are obligated to accept back returned reptiles for resale. From 2014 to 2017, at least 1,000 native...

... for most bat species. Our third case study used mark-recapture of banded bats to estimate population dynamics in an experimental forest with environmental protection similar to that practised today in NSW forests (protection of riparian zones; habitat trees, rainforest). Analysis of 14 years of annual...

...Michael Calver; Grant Wardell–Johnson ABSTRACT Impacts on the forested bioregions of south–western Australia have, since first European settlement in 1826, been extensive and dramatic. Large–scale land clearing removed over two–thirds of the vegetation for agriculture and urbanisation. Other...

...Jo-Anne Chuck; Julie Old This case study describes the conflicts between the needs of a university animal ethics committee to meet legislative requirements and the pedagogical outcomes for third year undergraduate project students working with animals in an Australian context. The projects...

..., no tagged frogs were recorded to move between them. In contrast, one female bell frog moved 1.25 km between one of these and the third site over a 14 month-period. The ratio of male to female frogs was 2.5:1, suggesting either that the population is male-dominated or that females are more cryptic...

... that immediately a habitat goes so does the species dependent on it. Only one-third of the 108 forest and woodland species discussed occur in multiple habitats and hence are well insulated against change. The use of progressively degraded habitats is explored and it is found that only a very few species can...

... in Southwestern Victoria together with those from Naracoorte in South Australia form a southern phonotype ( M. s. bassanii ). Bats from East Gippsland in Victoria through to Torres Strait form the eastern phonotype ( M. s. oceanensis ). Bats from the Northern Territory form the third phonotype ( M. s. orianae...

... their second or third year of life, and are then capable of producing just one young per year. Such a breeding strategy will be successful only if flying-foxes are long-lived and suffer naturally low mortality rates. In this paper,we assess the vulnerability of flying foxes to extinction, using basic...
