The density of redshank Tringa totanus breeding on the salt-marshes of the Wash in relation to habitat and its grazing management
Coastal salt-marshes in Great Britain are of both national and international significance for their breeding redshank Tringa totanus populations. These habitats are currently under threat, as aExpand
Selective Herbicides Reduce Alligator Weed (Alternanthera Philoxeroides) Biomass by Enhancing Competition
Abstract Physical and chemical methods of managing invasive plants (weeds) create disturbances that paradoxically often promote these species because weeds tend to have traits that confer competitiveExpand
Is the density of redshank Tringa totanus nesting on saltmarshes in Great Britain declining due to changes in grazing management
1. Saltmarsh habitats support c. 50% of the population of redshank Tringa totanus breeding in Britain. Between 1985 & 1996, breeding densities declined significantly by 23%. This paper tests theExpand
Rickets in yearling steers wintered on a swede (Brassica napus) crop.
Rickets was diagnosed in a group of 80 yearling Angus steers wintered for three months on a crop of swedes (Brassica napus) in the Kimbolton area. Growth rate was poor and several steers developedExpand
A new glyphosate resistant weed species confirmed for northern New South Wales and the world : common sowthistle ( Sonchus oleraceus )
Two populations of common sowthistle (Sonchus oleraceus L.) were reported to survive straight applications of glyphosate in northern New South Wales. These were subsequently proven to be glyphosateExpand
The abundance and conservation status of redshank Tringa totanus nesting on saltmarshes in Great Britain
Abstract We report the results of two surveys of the same sample of 77 saltmarsh sites around the coast of Great Britain, conducted in 1985 and 1996 to estimate breeding abundance and theExpand
Disturbance-mediated competition: the interacting roles of inundation regime and mechanical and herbicidal control in determining native and invasive plant abundance
Disturbance is a key component of many successful plant invasions. However, interactions among natural and anthropogenic disturbances and effects of these interacting disturbances on invasive plantsExpand
Phosphorus deficiency in a dairy herd.
Phosphorus deficiency was diagnosed in a 90 cow seasonal supply dairy herd which showed low milk production, ill-thrift, infertility and osteophagia. Serum inorganic phosphorus and pasture phosphorusExpand
Glyphosate resistance in awnless barnyard grass (Echinochloa colona (L.) Link) and its implications for Australian farming systems.
Awnless barnyard grass ( Echinochloa colona (L.) Link) is one of the top five major weeds of world agriculture (Holm et al. 1977). In Australia, it is a serious weed of sorghum, maize, rice and sugarExpand
