Historical records, and the names of animals within Aboriginal languages, were analysed to compare the distribution and density of kangaroos at European contact with those of today. We gave up this attempt for the Eastern Grey Kangaroo, Macropus giganteus, presently restricted to the extreme south-east of the state, because it was never differentiated historically from the Southern Grey Kangaroo, M. fuliginosus, which occurs right across the southern portion of the state. The historical distribution of the latter species, and of the Red Kangaroo, M. rufus, seems to have been similar to their distribution today. Past densities are difficult to extract from historical records and are not sufficiently reliable to justify comparison with present densities. We note however an apparent increase in density of 'kangaroos' in the mid-1800s.

Historic Data

The dominant species of large macropods in Victoria are the Eastern Grey Kangaroo (Macropus giganteus) and the Southern (= Western) Grey Kangaroo (M. fuliginosus). On the limited historic data available there is no indication that their ranges have changed since European settlement. The Red Kangaroo (M. rufus) was restricted to the northwest corner of the state, then as now. Moderate densities of Grey Kangaroos at settlement increased under forest clearing, probably peaking about the mid-nineteenth century. With intensification of farming and associated heavy hunting they declined again to establish by about the turn of the century the distribution of modera te density that we see today.

Red and western grey kangaroos were surveyed from the air in Western Australia during the winter of 1981. The area covered, 1 528 000 km2 or 61% of the State, excluded only the Kimberleys in the north and the Gibson and Great Sandy Deserts of the interior. Hence almost all kangaroo range within the State was surveyed, to provide an estimate of 980 000 reds and 436 000 greys. Densities were much lower than those of the eastern States. Red kangaroos were most abundant in mulga shrubland, chenopod shrubland and tussock grassland, and least abundant in hummock grassland. Densities were associated strongly with land-use categories, being high in areas used for extensive sheep grazing and low in vacant Crown Land and arable land. In contrast to reds the western grey kangaroos were confined to the south and west of the state, their distribution being related more directly to climate than to vegetation or land use. They live in the winter rainfall zone. We suggest that their restricted breeding season results in peak nutritional demands associated with lactation, and hence energy requirements, being synchronized with the spring flush of pasture following winter rains. Approximately 14% of the red kangaroo and 8% of the western grey kangaroo populations in Western Australia were harvested legally in 1981.

We present a new record of the Crested Eagle, Morphnus guianensis (Daudin, 1800), a rare forest eagle of the Neotropics on 22 May 2012 at a Cerrado area in Minas Gerais state, southeastern Brazil. The species has only two historical records in the state, both at areas formerly covered by Atlantic Forest. The finding raises the expectations for the maintenance of the species in the state, stressing the fact that this is the first species record in a Cerrado area in Eastern Brazilian states.

ABSTRACT Collections of mosquitoes were conducted for the surveillance of species of medical importance in the state of Morelos, Mexico, in June 2017. Species collected included Mansonia (Mansonia) dyari, which was identified using morphological characters and cytochrome c oxidase I DNA barcoding. Although 3 species of genus Mansonia have been previously reported in Mexico, this is the 1st confirmed record of Ma. dyari in Morelos State, where no Mansonia species had been recorded. Historical records of Ma. dyari and Ma. indubitans in Mexico were reviewed. Therefore, this record increases the number of mosquito species occurring in Morelos to 46. The specimens collected in this study were deposited in the Culicidae collection of the Universidad Autónoma Agraria Antonio Narro, Unidad Laguna.

Objective: To document aspects of the history of alcohol use among Maori, with a particular focus on the period from 1840 to 1872 and to identify potential use of this knowledge in the development of strategies for the prevention and treatment of alcohol-related harm among Maori in contemporary New Zealand. Method: A survey of the surviving documentation about alcohol in nineteenth-century New Zealand; materials were predominantly drawn from the writings of pakeha (non-Maori) missionaries, officials and travellers, as well as available statistical records. Results: Analysis of early written historical records suggests significant variation in the response of Maori to the introduction of alcohol in different parts of New Zealand during the period following European contact. Conclusions: One stereotype that has arisen suggests Maori have been incapable of and/or unable to manage the production and use of alcohol. On the other hand, another commonly held belief has been that Maori supported abstinence or ‘resisted alcohol’ because they recognised its ‘ruinous nature’ and because it was contrary to traditional custom and practices. Historical information indicates that the Maori response to the introduction of alcohol was in fact diverse and for much of the nineteenth century alcohol was non-problematic for many Maori. This reinterpretation of the historical record can potentially empower contemporary Maori to take greater responsibility for the use of alcohol. It also challenges the negativity of the stereotypes generated by historical misinformation.

Acinar Tissue

The development of the endocrine pancreas in kangaroos was examined histologically with tissue from three kangaroo species, the red kangaroo Megaleia rufa, the euro Macropus robustus erubescens, and the grey kangaroo Macropus giganteus. The relative size of the pancreas of the pouch young was found not to differ significantly from that of adults. Stages of pancreatic development were described from the frequency of the occurrence of the pancreatic epithelial ducts and the B or insulin-secreting cells, while the development and distribution of the A2 or glucagon-producing cells was also observed. In pouch young of less than 22 days of age the pancreas is dominated by ductular epithelial and undifferentiated pancreatic cells. From days 42 to 97 of pouch life B endocrine cells tend to be concentrated together and ductular tissue encroaches into areas previously dominated by connective tissue. After 120-135 days the first A2 cells are apparent and are usually located at the periphery of the islets, which now take on a distinctive appearance as the acinar tissue expands and separates them. After 135 days of pouch life A2 cells outnumber B cells; the endocrine tissue assumes an adult appearance after 150-160 days. The major difference between the development of pancreatic tissue in foetal sheep and pouch-young kangaroo is the prolonged dominance of connective tissue and the slow development of endocrine tissue in the former.
