Comparison of sapwood invasion by three Phytophthora spp. in different hosts

Autor: E. J. Speijers, Elaine Davison, Francis Tay

Publikováno v: Australasian Plant Pathology. 43:487-493

Many Phytophthora spp. have recently been isolated from native vegetation in Western Australia. As their pathogenicity is often unknown, it is not possible to provide advice to land managers on the impact of site infestation on native plants and how

This experiment evaluated the productivity of 500 Angus cows that differed in genetic merit for either subcutaneous rib fat depth (Fat) or residual feed intake (RFI) based on estimated breeding values (EBVs) and managed under two levels of nutrition.

Australian seedstock cattle breeders have expressed concerns that while there has been genetic improvement in feedlot and abattoir performance of cows, it could have led to a decline in maternal productivity, especially under variable nutritional con

A study of the bioequivalence of corynetoxins and tunicamycins: the effect of these toxins on the viability and morphology of rat hepatocytes in tissue culture

Autor: J. G. Allen, M. Retallick, M. Kowalski, S. M. Colegate, E. J. Speijers, T. Doran, W. Michalski

The effects of corynetoxins (from Lolium rigidum) and tunicamycins on hepatocyte viability and morphology were indistinguishable providing further evidence that these 2 related toxins have equivalent bioactivity and continue to support use of the tun
