Use Of Cellular Automata Modelling Approaches To Understand Potential Impacts Of Gm Grasses On Grassland Communities, R. Colasanti, R. Hunt, L. S. Watrud
Use Of Cellular Automata Modelling Approaches To Understand Potential Impacts Of Gm Grasses On Grassland Communities, R. Colasanti, R. Hunt, L. S. Watrud
IGC Proceedings (1993-2023)
In order to predict the potential unintended ecological impacts of genetically modified (GM) grasses, we must understand how the engineered traits, in this case herbicide resistance, are expressed in an ecological context. It would be a daunting task to experimentally evaluate the full multiplicity of potential pair-wise interactions between GM plants and native plants under a broad variety of actual environmental conditions. We have employed the modelling methodology of cellular automata (CA), where a plant's distribution within a two-dimensional environmental grid is determined by rules relating to phenomena such as seed dispersal, clonal expansion and interactions with adjacent plants. We …
Pollen-Mediated Gene Flow From Genetically Modified Herbicide Resistant Creeping Bentgrass, L. S. Watrud, E. H. Lee, A. Fairbrother, C. Burdick, J. R. Reichman, M. Bollman, M. Storm, G. King, P. K. Van De Water
Pollen-Mediated Gene Flow From Genetically Modified Herbicide Resistant Creeping Bentgrass, L. S. Watrud, E. H. Lee, A. Fairbrother, C. Burdick, J. R. Reichman, M. Bollman, M. Storm, G. King, P. K. Van De Water
IGC Proceedings (1993-2023)
Approximately 162 ha of multiple experimental fields of creeping bentgrass (Agrostis stolonifera L.) genetically modified for resistance to Roundup ®herbicide, were planted in central Oregon in 2002. When the fields flowered for the first time in the summer of 2003, a unique opportunity was presented to evaluate methods to monitor potential pollen-mediated gene flow from the experimental GM crop fields to compatible sentinel and resident plants that were located in surrounding, primarily non-agronomic areas.
Modelling Contamination Of Raw Milk With Butyric Acid Bacteria Spores, M. M. M. Vissers, F. Driehuis, P. De Jong, M. C. Te Giffel, J. M. G. Lankveld
Modelling Contamination Of Raw Milk With Butyric Acid Bacteria Spores, M. M. M. Vissers, F. Driehuis, P. De Jong, M. C. Te Giffel, J. M. G. Lankveld
IGC Proceedings (1993-2023)
Raw milk contains low concentrations of bacterial endospores, originating from the farm environment (e.g. soil, feeds, faeces). Spores of Clostridium tyrobutyricum, also called butyric acid bacterium (BAB), are of great interest to the dairy industry. They survive milk pasteurisation and cause off-flavours and texture defects in various cheese types. The contamination pathway of BAB spores is well known. Their primary origin is soil. In silage the number of spores will increase if conditions permit BAB growth. The spores are excreted in the cows faeces and are transferred to milk by contaminated teat surfaces. Many factors are involved in the …

Benefits And Uses Of Nematodes In Grassland Soils, Michael J. Wilson
Benefits And Uses Of Nematodes In Grassland Soils, Michael J. Wilson
IGC Proceedings (1993-2023)
To most grassland farmers nematodes mean trouble: they are important parasites of both pasture plants and livestock. While there is no doubting the considerable losses caused by nematodes, crop and livestock pests represent a tiny minority of the approximately 26,000 described nematode species. Here I examine the beneficial effects of nematodes within grassland systems and their beneficial uses. Nematodes in grassland soils increase plant available nutrients, move beneficial microbes through the rhizosphere and control insect and mollusc herbivores. We can use nematodes as biological control agents, and also as indicators of soil health/quality. While no single group of organisms can …

Introduction Over the past decade, the potential for drug-associated progressive multifocal leukoencephalopathy (PML) has become an increasingly important consideration in certain drug development programmes, particularly those of immunomodulatory biologics. Whether the risk of PML with an investigational agent is proven (e.g. extrapolated from relevant experience, such as a class effect) or merely theoretical, the serious consequences of acquiring PML require careful risk minimisation and assessment. No single standard for such risk minimisation exists. Vedolizumab is a recently developed monoclonal antibody to α4β7 integrin. Its clinical development necessitated a dedicated PML risk minimisation assessment as part of a global preapproval regulatory …
