... After evaluation of relevant recent geological and systematic literature, a scenario of the history of land mammals in the Australo-Pacific region is developed, as follows. Monotremes probably originated in the Australian section of Gondwana during the Cretaceous. Australidelphians reached...

... metapopulation), had an unacceptably high probability of glider extinction after 100 years. When catastrophes such as wildlfire of modest frequency (1 in 20 years) were included, the probability of extinction increased. It appears that large nearby remnants must be functionally linked to the metapopulation...

... adjustments in their own timing. To do this they probably monitor a suite of environmental conditions. It has been proposed that if a signal changed in isolation from other factors it would be ignored. For example, it is important that a nomadic species be not directly responsive to photoperiod since...

.... There are problems of scale in undertaking the appropriate scientific study of the possible impacts of forestry activities on native fauna. Then there is also the long time frame of logging cycles. Given sufficient time highly improbable contingencies have a propensity to become probable. An indirect answer...

... a relatively low (≤ pH ~6.5) and constant water pH and the apparent advantage to tadpoles of H. australiacus of a high sediment load, probably reflects their sensitivity to pH rather than an affect of sediment per se . Tadpoles of both species are probably capable of surviving in streams that are subjected...
