Search Reset Limited effectiveness of actions intended to achieve a voluntary transition from the use of lead to non-lead shotgun ammunition for hunting in Britain Author: Green, R.E., Taggart, M.A., Pain, D.J., Clark, N.A., Clewley, L., Cromie, R., Green, R.M.W., Guiu, M., Huntley, B., Huntley, J., Leslie, R., Porter, R., Roberts, J., Robinson, J.A., Robinson, R.A., Sheldon, R., Smith, K.W., Smith, L., Spencer, J. & Stroud, D. Published: 2023 The SHOT-SWITCH project was set up to monitor the effectiveness of voluntary initiatives to move away from the use of lead shot in game shooting. In the study’s third season, reported here, 94% of Pheasants sampled had been killed using lead ammunition, a slightly but significantly smaller proportion than in the preceding two seasons. There is currently no evidence that voluntary initiatives to promote the replacement of lead with non-lead ammunition by suppliers and retailers of wild-shot game are working. 28.02.23 Papers View on journal website The conservation of Afro-Palaearctic migrants: what we are learning and what we need to know Author: Vickery, J.A., Mallord, J.W., Adams, W.M., Beresford, A.E., Both, C., Cresswell, W., Diop, N., Ewing, S.R., Gregory, R.D., Morrison, C.A., Sanderson, F.J., Thorup, C., Van Wijk, R.E. & Hewson, C.M Published: 2023 The populations of many migrant birds have been in decline for decades, prompting research to understand the nature of these declines so that they can be addressed. The highly complex annual cycles of migrant birds, with their long migration routes and a dependence on different sites at different times of the year, makes it very difficult to identify the drivers of decline and to implement conservation action. While our knowledge is still incomplete, can we afford to wait until we have all of the answers? 15.02.23 Papers View on journal website Collation of a century of soil invertebrate abundance data suggests long-term declines in earthworms but not tipulids Author: Barnes, A.E., Robinson, R.A. & Pearce-Higgins, J.W.

Published: 2023 The long-term declines evident in many bird and invertebrate species have their origins within a suite of potential drivers, one of which is climate change. As well as impacting bird species directly, could climate change be increasingly hitting bird populations through its impacts on their invertebrate prey? 09.01.23 Papers View on journal website Pagination First page First Previous page Previous … Duilleag 16 Duilleag 17 Duilleag 18 Duilleag 19 Duilleag 20 Duilleag 21 Duilleag 22 Duilleag 23 Duilleag 24 … Next page Next Last page Last
