Correcting bulk density measurements made with driving hammer equipment
Parfitt, R.L.; Ross, C.W.; Schipper, Louis A.; Claydon, J.J.; Baisden, W. Troy; Arnold, Greg (Elsevier, 2010)Accurate measurement of dry bulk density is critical for determining stocks of elements such as carbon or nitrogen, in soils. During investigations of changes of soil carbon with time, we resampled soil profiles for bulk ... -
Effect of grazing on ship rat density in forest fragments of lowland Waikato, New Zealand
Innes, John G.; King, Carolyn M.; Bridgman, Lucy Jade; Fitzgerald, Neil; Arnold, Greg; Cox, Neil R. (New Zealand Ecological Society, 2010)Ship rat (Rattus rattus) density was assessed by snap-trapping during summer and autumn in eight indigenous forest fragments (mean 5 ha) in rural landscapes of Waikato, a lowland pastoral farming district of the North ... -
Native bird abundance after Australian magpie (Gymnorhina tibicen) removal from localised areas of high resource availability
Morgan, Dai K.J.; Waas, Joseph R.; Innes, John G.; Arnold, Greg (New Zealand Ecological Society, 2012)Many reports exist of Australian magpies (Gymnorhina tibicen) attacking and sometimes killing other birds. One study concluded that magpies had little impact on the abundance of other birds at landscape scales, but another ... -

Trends in soil carbon and nutrients of hill-country pastures receiving different phosphorus fertilizer loadings for 20 years
Schipper, Louis A.; Dodd, M.B.; Fisk, L.M.; Power, I.L.; Parenzee, Jacinta; Arnold, Greg (Springer, 2010)There are few records of long-term trends in soil C and N in grazed pasture systems but recent measurements have demonstrated unexplained losses on New Zealand lowlands. To determine whether losses were also occurring in ...
