... favoured a route which would have divided the two major wilderness areas of the Gippsland forests in Victoria by creating a fenced impenetrable barrier to some wildlife. Planning authorities need to address the impacts of fragmentation of natural habitats by such developments. Although it is difficult...

... these searches. Additional diurnal searches for tadpoles proved to be the most efficient method to detect the species and locate breeding sites. Of 102 sites surveyed, fragmented populations were found at 27 by the presence of tadpoles and adult frogs. The vegetation at these sites was woodland and open forest...

...Alexandra J. R. Carthey ABSTRACT Artificial habitat holds broad appeal as a tangible and seemingly direct ‘fix’ for the ongoing loss and fragmentation of wildlife habitat, despite a lack of sufficiently rigorous evidence demonstrating benefit for target wildlife. The common focus on replacement...

... restoration are urgently needed that suit the small fragments of space available, and that can deliver multiple benefits not only to conserve urban biodiversity but also to reconnect people with nature. To overcome these challenges, an ‘ecology with cities’ perspective, combining horticultural, ecological...

... settlement of Noosa Shire, South-east Queensland, with particular emphasis on the economic and political drivers and the resultant loss and fragmentation of Koala Phascolarctos cinereus habitat. Patterns of habitat loss between 1860 and 1970 were quantified at a coarse level from historical and land tenure...

...Geoff Williams; Paul Adam Pollination is an essential process in the life cycle of most flowering plants and thus maintenance of the process is necessary for the long-term maintenance of rainforest ecosystems and their associated biota. As rainforest stands become fragmented will disruption...

...Murray Ellis; Jennifer Taylor The woodlands of southern Australia have been extensively cleared for agriculture. The loss and fragmentation of the native vegetation has been followed by dramatic declines in woodland-dependant species. Here we present data from the Central Western Plains of New...

.... By night, utilisation was 80% E. tereticornis . Analysis of cuticle fragments in faecal pellets revealed almost 100% of the diet was composed of E. tereticornis . Nocturnal tree species utilisation differed from day use and from species occurrence in the diet. Direct observations of koala over 24 hrs found...

... to the rainforested headwater reaches of each of the nine streams it inhabits, and large areas of cleared, agricultural land separate the species into three disjunct areas on the Richmond Range and the Yabbra Spur. Euastacus gumar is a narrow range taxon with a fragmented, highland distribution (overall extent...

..., and colonies abandoning less productive habitats. Nests were spaced over a wide height range, but most were in the lower canopy of eucalypts. Nesting was not synchronous. Their decline can be attributed to the fragmentation and clearing of the most productive habitats in WA for agriculture and urban expansion...

... the impacts of fire in future. Such monitoring will need to incorporate the effects of other disturbance factors, such as habitat fragmentation, drought, salvage logging and longwall mining, that interact with fire, and also trial new methods to track and assist fauna to cope with the changing fire regimes...

... that such aggression could affect the abundance and distribution of small woodland birds, however, appears only in the period after World War II. The changing ecological role of Noisy Miners, and the associated changes in cultural attitude to the species, appear linked to the loss, fragmentation and degradation...
