Autor: J. Witkowski, K. Bryłka, S. M. Bohaty, E. Mydłowska, D. E. Penman, B. S. Wade

Publikováno v: Climate of the Past, Vol 17, Pp 1937-1954 (2021)

The Paleogene history of biogenic opal accumulation in the North Atlantic provides insight into both the evolution of deepwater circulation in the Atlantic basin and weathering responses to major climate shifts. However, existing records are compromi

Competition to collaboration: changing the dynamics of science

Autor: D. R. Penman, Stephen L. Goldson

Publikováno v: Journal of the Royal Society of New Zealand. 45:118-121

Our current approach to science has engendered excessive individual and institutional competition and complexity in funding instruments. We contend that a future science system will require a more collaborative approach that supports competition for

Phenology and relative abundance ofCeroplastes destructorandC. sinensis(Hemiptera: Coccidae) on citrus in Northland, New Zealand

Autor: Peter L. Lo, R. H. Blank, D. R. Penman

Publikováno v: New Zealand Journal of Crop and Horticultural Science. 24:315-321

The main scale insect pest in citrus orchards in Northland, New Zealand was Ceroplastes destructor although C. sinensis was more widespread. We studied the phenology of both species over 3 years by regularly sampling scales on leaves and wood for lab

Miticide bioassays with spider mites (Acari: Tetranychidae): effect of test design and sample size on the precision of lethal concentration estimates

Autor: D. R. Penman, R. B. Chapman, K. H. Kabir

Publikováno v: Experimental and Applied Acarology. 20:483-494

The effect of interval space between the concentration (symmetric or geometric), number of concentrations and overall sample sizes were investigated using a Petri dish bioassay, the miticide propargite and two spider mites species. The precision (wid
