Since 1976, the numbers of Oystercatchers Haematopus ostralegus wintering on the Exeestuary have fluctuated independently of the substantial increase over the same period in the numbers wintering in Britain as a whole. While this might imply that the

Numbers of Oystercatchers Haematopus ostralegus overwintering on the Exe estuary, south Devon, increased over the period 1976 to 1991. Mortality of colour-ringed adults also increased over this period. In this study, we tested for density-dependence

Introductions of non-native species are seen as major threats to ecosystem function and biodiversity. However, invasions of aquatic habitats by non-native species are known to benefit generalist consumers that exhibit dietary switches and prey upon t

The Manila clam Ruditapes philippinarum was introduced to Poole Harbour (lat 50°N) on the south coast of England in 1988 as a novel species for aquaculture. Contrary to expectations, this species naturalised. We report on individual growth patterns,

In behavior-based individual-based models (IBMs), demographic functions are emergent properties of the model and are not built into the model structure itself, as is the case with the more widely used demography-based IBMs. Our behavior-based IBM rep

An individuals-based model, MORPH, was used to assess the quality of Poole Harbour, UK, for five overwintering shorebirds: dunlin Calidris alpina, redshank Tringa totanus, black-tailed godwit Limosa limosa, oystercatcher Haematopus ostralegus and cur

The conservation importance of estuaries is often measured by bird numbers, but monitoring numbers is not necessarily a reliable way of assessing changes in site quality. We used an individual-based model, comprised of fitness-maximising individuals,

Intertidal estuaries in north–west Europe provide essential feeding grounds for internationally important numbers of overwintering shorebirds. Monitoring of the food supply available in these intertidal habitats is central to shorebird conservation

Bottom cultivation of mussels on intertidal flats is practiced throughout the world. This often generates conflicts between commercial interests and competing birds such as oystercatchers. At the Menai Strait, United Kingdom, the overwinter consumpti

In a number of extensive coastal areas in northwest Europe, large numbers of long-lived migrant birds eat shellfish that are also commercially harvested. Competition between birds and people for this resource often leads to conflicts between commerci
