Subspecific Level

Recent accounts of wild-living dogs in New Guinea argue that these animals qualify as an ‘evolutionarily significant unit’ that is distinct from village dogs, have been and remain genetically isolated from village dogs and merit taxonomic recognition at, at least, subspecific level. These accounts have paid little attention to reports concerning village dogs. This paper reviews some of those reports, summarises observations from the interior lowlands of Western Province and concludes that: (1) at the time of European colonisation, wild-living dogs and most, if not all, village dogs of New Guinea comprised a single though heterogeneous gene pool; (2) eventual resolution of the phylogenetic relationships of New Guinean wild-living dogs will apply equally to all or most of the earliest New Guinean village-based dogs; and (3) there remain places where the local village-based population of domestic dogs continues to be dominated by individuals whose genetic inheritance can be traced to precolonisation canid forebears. At this time, there is no firm basis from which to assign a unique Linnaean name to dogs that live as wild animals at high altitudes of New Guinea.

High Diversity

The Chelidae is a family of side-necked turtles restricted in distribution to South America and Australasia. While their biology in Australia is reasonably well known, species in New Guinea are very poorly known despite high diversity, especially in the southern lowlands. In this paper, we report on the diversity, distribution, habitat and reproductive biology of the freshwater turtles of the TransFly region of the Western Province of Papua New Guinea, with special emphasis on reproduction of Emydura subglobosa, Elseya branderhorsti and Elseya novaeguineae. Seven species were captured, with reliable records of an eighth. A key to the freshwater turtles of the TransFly region is provided. Harvest methods, consumption, and trade in turtles by the TransFly communities are documented. There is mounting pressure to take advantage of revenue opportunities afforded by the Asian turtle trade, but this is impeded by lack of transport infrastructure. There is also insufficient demographic information on any New Guinean turtle species to make a reasoned judgment on the level of harvest that would be sustainable. Nor is there sufficient information on captive rearing for most species, and where it is available it is not accessible by local villagers. These knowledge gaps need to be addressed and factored into a management plan that is implemented before local communities can capitalise on the commercial opportunities provided by the turtle fauna without risking collapse of the resource and the implications for their concurrent subsistence economy that would follow.

First Occurrence

This study aims to report the occurrence of parasitism byAmblyomma ovale (Koch, 1844) in dogs in the municipality of Apodi, Rio Grande do Norte, Brazil. Specimens were identified as being one female and two males of A. ovale, besides; the animal was infested by five females of Rhipicephalus(Boophilus) microplus and seven females and three males of R. sanguineus. The finding ofA. ovale confirms results in the literature that these ticks, reported in several species of wild carnivores, can also infect dogs in Brazil. The distribution of this tick species in several Brazilian states has already been confirmed, but this is the first report in the State of Rio Grande do Norte. This finding highlights the risk of the carrying of emerging and re-emerging pathogens to peridomestic hosts are as, either because of the frequency of these ticks in wild environments or the presence of infected wild animals near peridomestic environments, exposing domestic dogs to parasitism byA. ovale ticks and, therefore, to agents potentially carried by this ectoparasite.

Phylogenetic Relationships ◽  
New Guinea

The standard and C-banded chromosomes of 10 species from eight genera of New Guinea rodents are described. The data show that Anisomys, Lorentzimys, Pogonomys and possibly Chiruromys, previously karyotyped by Dennis and Menzies (1979), appear to form a clade by virtue of a shared Robertsonian rearrangement. The karyotypes of the two Uromys species examined differ by multiple rearrangements. Further investigations of these species and their New Guinean congeners may provide a framework for the resolution of the systematics of Australo-Papuan Uromys.

Papua New Guinea (PNG) has a high burden of tuberculosis (TB), including drug-resistant TB (DR-TB). DR-TB has been identified in patients in Western Province, although there has been limited study outside the provincial capital of Daru. This study focuses on the Balimo region of Western Province, aiming to identify the proportion of DR-TB, and characterise Mycobacterium tuberculosis (MTB) drug resistance-associated gene mutations. Sputum samples were investigated for MTB infection using published molecular methods. DNA from MTB-positive samples was amplified and sequenced, targeting the rpoB and katG genes to identify mutations associated with rifampicin and isoniazid resistance respectively. A total of 240 sputum samples were collected at Balimo District Hospital (BDH). Of these, 86 were classified as positive based on the results of the molecular assays. For samples where rpoB sequencing was successful, 10.0% (5/50, 95% CI 4.4–21.4%) were considered rifampicin-resistant through detection of drug resistance-associated mutations. We have identified high rates of presumptive DR-TB in the Balimo region of Western Province, PNG. These results emphasise the importance of further surveillance, and strengthening of diagnostic and treatment services at BDH and throughout Western Province, to facilitate detection and treatment of DR-TB, and limit transmission in this setting.
