Models Relating Individual Tree Basal Area Growth Rates to Tree Basal Areas in Even-Aged, Monoculture Forest Stands
Autor: PW West, DA Ratkowsky
Publikováno v: Journal of Forests. 9:21-38
As trees grow larger in even-aged, monoculture forests, stand density increases, taller trees shade smaller trees and a group of smaller, suppressed trees develops that may show little or no growth. Subsequent mortality is most common from this group

Autor: AV Ratkowsky, DA Ratkowsky
Publikováno v: Emu - Austral Ornithology. 78:223-226
A winter survey of the avifauna of the Mt Wellington Range, Tasmania, was carried out between 5 May 1977 and 2 October 1977 and compared with a previous survey conducted during the main breeding months. Several non-migratory species were observed to

Autor: DA Ratkowsky, AV Ratkowsky
Publikováno v: Papers and Proceedings of The Royal Society of Tasmania. 110:63-90
A census of the vascular plants of the Mt. Wellington Range, Tasmania, is reported, the survey having been carried out in the two-year period between February 1973 and March 1975, i.e. six to eight years after the devasting bushfire of 7th February 1

The Birds of the Mt Wellington Range, Tasmania
Autor: DA Ratkowsky, AV Ratkowsky
Publikováno v: Emu - Austral Ornithology. 77:19-22
The avifauna of the Mt Wellington Range, Tasmania, was observed at elevations above 240 metres during the period 1 October 1975 to 31 January 1976. A total of sixty-two species was recorded and for each observation note was taken of the habitat in wh

Autor: KC Wilson, DA Ratkowsky, TG Dix
Publikováno v: Marine and Freshwater Research. 26:223
Total mercury concentrations are reported for 258 individuals representing 16 species of finfish from the Derwent Estuary, Tasmania. Mercury concentrations in the muscle tissue varied between undetectable levels and a value of 2.0 mg/kg in one specim

The use of multivariate analysis in identifying relationships among disorder and mineral element content in apples
Autor: D Martin, DA Ratkowsky
Publikováno v: Australian Journal of Agricultural Research. 25:783
The use of principal component analysis, followed by rotation of a reduced number of component axes, and its role in the identification and interpretation of relationships between disorder and mineral content in apple research is described. The relat

Photosynthesis of wheat under field conditions. IV. The influence of density and leaf area index on the response to radiation
Autor: DA Ratkowsky, DW Puckridge
Publikováno v: Australian Journal of Agricultural Research. 22:11
The photosynthesis of two cultivars of wheat at three densities of sowing was measured during the growing season of 1968. When the data were plotted as carbon dioxide uptake versus leaf area index (LAI) (leaf laminae and green stem) for a fixed value
