Plant Classification And Nomenclature In Ndumba, Papua New Guinea Highlands, Terence Hays

Traditionally, the terms "ethnobotany" and "ethnozoology" have designated little more than the study of plant and animal utilization. In the past two decades, however, the ways in which the components of given biological environments are locally perceived and categorized have received increasing attention. Not only has the study of ethnobiological classification been recognized as essential to a wide variety of ethnographic concerns (cf. Frake 1962; Bulmer 1967), but the discovery of possible universals in folk classification systems promises to enrich our understanding of human cognitive processes as well (Berlin et al. 1973; Brown 1977).
The paucity of comprehensive studies of …

For Papua New Guineans,l as well as for those who wish to understand them better, traiditional knowledge of the local natural environment is a priceless resource. In the face of increasing commitments to a cash economy, however, many communities are rapidly losing their awareness and appreciation of the rich animal and plant worlds which are immediately available to them. As Powell has recently observed (1976), the recorded information regarding traditional plant knowledge and uses has tended to be widely-scattered in the literature and relatively difficult to access, especially for those who stand to benefit the most from it. A recent …

Purification And Characterization Of Novel Nucleases From A Thermophilic Fungus, Kyle Landry
Kyle S Landry
A thermophilic fungus was isolated from composted horse manure. The organism was as a Chaetomium sp. by sequencing the highly conserved ITS region of the fungus and comparing to known regions in a genomic database and was referred to as TM-417. TM-417 was found to have an optimal growth temperature of 45 oC and an optimal pH of 7.0. An extracellular DNase and RNase was found to be produced by the isolate and were purified 145.58-fold and 127.6-fold respectively using a combination of size exclusion chromatography and a novel affinity membrane purification system. The extent of purification was determined …
