The former and current distribution of the quokka, Setortix brachyurus, was mapped from published and all available unpublished records.

At the time of European settlement the quokka was widespread and abundant and its distribution encompassed an area of approximately 41 200 km2 of south-west Western Australia inclusive of two offshore islands, Bald Island and Rottnest Island. Historical reports indicated an extensive population decline occurred in the 1930s. The decline continued, with a previously undocumented decline apparent in the period from 1980 to 1992. However, this decline may be an artefact of the time scales used for mapping and may well equate with a previously reported decline lor a suite of south -west mammals in the 1970s. By 1992 the quokka´s distribution had been reduced to an area of approximately 17800 km2. An increased awareness of the presence of the quokka on the mainland has resulted in numerous reportings of quokka presence since 1992, has confimled the existence of several populations at the northern extent of the quokka´´s known geographic range and indicated the cmrent, 2005, distribution to be similar to that in 1992. However, survey and population estimates at six of these mainland locations from the northem jarrah forest indicated low abundance. There have been no population estimates elsewhere on the mainland. Two populations have been reported tiom the Swan Coastal Plain, but neither has been confirmed extant. Predation by the introduced fox, Vulpes vulpes, is implicated as a major cause of the quokka´s initial decline, while ongoing predation, habitat destruction and modification through altered tire regimes have contributed to the continued decline. Specific conservation management actions are recommended, namely: (i) Implementing an active adaptive management program in the northern jarrah forest to determine quokka population response to habitat manipulation through the use of fIre, fox baiting and pig control; (ii) Surveying the Stirling fumge and Green Range populations with emphasis placed on determining population size and population genetic structure; (iii) Surveying the reported occurrences from the Swan Coastal Plain, with emphasis on unambiguously determining presence. If confirmed, priority should he directed to assessing population size and determining the management requirements to ensure persistence of the population; (iv) Surveying southem forest and south coast populations to assess quokka population size, the extent of movement between sllbpopulations and assessment of the range of habitat types used by quokkas. The latter should be combined with spatial analyses of known extant populations and suitable and potentially suitable habitat; (v) Determining the role of tire in establishing and maintaining preferred habitat of southern forest and south coast populations; and (vi) Establishing a program to assess the potential effects from management operations.

When the concept of the auteur was coined in the 1950s and 1960s, it was an initiative to clarify the obscure matters of authorship in cinema. Because a film must necessarily be a collective work, understood as the result of a large number of creative contributions, it was often unclear who the decisive power behind a certain film was, who contributed the "distinctive quality". The control will usually belong to the director, the producer or the star (or all three in combination), but what singles out a given film could also come from the cinematographer, the scriptwriter, from the author of an adapted literary work, or from traditions in the studio or in the genre. Nothing can be taken for granted about a film's authorship, it can only be decided through a thorough analysis of each film's production process, an analysis that, in most cases, will be impossible to make. ...
Total body water increases in pregnancy and while the uterus, placenta, fetus, and amniotic fluid constitute part of this increase, the largest component is in the extracellular water. Fat stores also increase and thus the distribution volumes of all drugs expand, but the major effect is seen in polar drugs which are confined to the extracellular space. Cardiac output and renal function also increase and elimination of polar drugs is acelerated. In contrast, the elimination of lipophilic drugs may be retarded, and the effect on intermediate drugs is variable. Polar drugs cross the placenta slowly and accumulate in amniotic fluid and therefore in the fetal gut lumen. Lipophilic drugs cross the placenta rapidly and their transplacental distribution is dependent on relative maternal and fetal affinity: this is determined largely by protein binding on either side of the placenta. The. fetus and neonate dispose of all drugs less rapidly than adults, the most efficient elimination processes being sulphate conjugation and renal excretion.
A skeletal world revision of the genus is presented to accompany a family account for Flora Malesiana. 82 species are recognised, of which 74 occur in the Malesiana region. Six species are desctibed as new, one species is raised from infraspecific status, and five species are restored from synonymy. Many names are typified for the first time. Three widespread, or locally abundant hybrids are also included. Full descriptions are given for new (6) or recircumscribed (7) species, and emended descriptions of species arc given where necessary (9). Critical notes are given for all the species. Little known and excluded species are discussed. An index to all published species names and an index of exsiccatae is given.
Aboriginal migration from South East Asia is the beginning of Australian economic history. Prehistorians have tended to focus on means to sea travel rather than opportunity and motive to migrate. American and Australian measures of sea depth contours throw new light on possible migration paths and the conditions that might have prompted Aboriginal ancestors to move through island SE Asia to Australia. Interpretation of the data depends on a reconsideration of palaeodemography and the introduction of some economic and historical analysis. Several scenarios suggest possible conditions influencing trends and fluctuations in Aboriginal migration over the past 60,000 years.
