| bone lead levels and lead isotope ratios in red grouse from scottish and yorkshire moors. | leg and foot bones of adult and juvenile red grouse (lagopus lagopus scoticus) were collected from hunter-shot birds on two scottish estates (glendye and invermark) and one yorkshire estate in september, 2003. the lead content of bones was measured by atomic absorption spectrophotometry, and corresponding stable lead isotopes (pb(204, 206, 207, 208)) by inductively coupled plasma mass spectrometry. at the glendye (n=111) and invermark (n=85) estates, relatively few birds (5.4% and 3.5%, respecti ... | 2009 | 19264349 |
| can acaricide-impregnated leg bands fitted to female red grouse reduce sheep tick parasitization of chicks and increase chick survival? | in parts of northern england, north wales and the scottish highlands, increasing numbers of sheep ticks ixodes ricinus (ixodida: ixodidae), and the louping ill virus they can carry, are considered to be important factors that reduce red grouse lagopus lagopus scotica productivity. the present study tested this hypothesis by fitting adult female grouse with leg bands impregnated with the acaricide cypermethrin to experimentally control ticks on their chicks on two managed grouse moors in northeas ... | 2016 | 27377883 |
| the long term response of birds to climate change: new results from a cold stage avifauna in northern england. | the early mis 3 (55-40 kyr bp associated with middle palaeolithic archaeology) bird remains from pin hole, creswell crags, derbyshire, england are analysed in the context of the new dating of the site's stratigraphy. the analysis is restricted to the material from the early mis 3 level of the cave because the upper fauna is now known to include holocene material as well as that from the late glacial. the results of the analysis confirm the presence of the taxa, possibly unexpected for a late ple ... | 2015 | 25992609 |
