Diurnal activity budgets of breeding Eurasian Oystercatchers Haematopus ostralegus feeding on limpets on rocky shores
The effect of different stages of the tidal cycle, weather conditions and the presence of conand allo-specifics on the time and activity budgets of Eurasian Oystercatchers Haematopus ostralegus was investigated. Data were collected at a breeding site on Lundy Island in the Bristol Channel, UK, where Oystercatchers feed on limpets Patella spp. on rocky shores. Sixteen behaviours were recorded fo...
متن کاملDisseminated neoplasia in cockles Cerastoderma edule: ultrastructural characterisation and effects on haemolymph cell parameters.
Disseminated neoplasia (DN) has been detected in cockles from various beds in Galicia (NW Spain). A study was performed to characterise cockle neoplastic cell ultrastructure and to evaluate the effect of this disease at different severity stages on various haemolymph cell parameters. Examination of cockle neoplastic cells with transmission electron microscopy (TEM) showed round shapes and a lac...
متن کاملPotential use of fatty acid profiles of the adductor muscle of cockles (Cerastoderma edule) for traceability of collection site
Geographic traceability of seafood is key for controlling its quality and safeguarding consumers' interest. The present study assessed if the fatty acid (FA) profile of the adductor muscle (AM) of fresh cockles (Cerastoderma edule) can be used to discriminate the origin of specimens collected in different bivalve capture/production areas legally defined within a coastal lagoon. Results suggest ...
متن کاملA fundamental study revisited: Quantitative evidence for territory quality in oystercatchers (Haematopus ostralegus) using GPS data loggers
A fundamental study by Ens et al. (1992, Journal of Animal Ecology, 61, 703) developed the concept of two different nest-territory qualities in Eurasian oystercatchers (Haematopus ostralegus, L.), resulting in different reproductive successes. "Resident" oystercatchers use breeding territories close to the high-tide line and occupy adjacent foraging territories on mudflats. "Leapfrog" oystercat...
متن کاملA silver spoon for a golden future: long-term effects of natal origin on fitness prospects of oystercatchers (Haematopus ostralegus).
1. Long-term effects of conditions during early development on fitness are important for life history evolution and population ecology. Using multistrata mark-recapture models on 20 years of data, we quantified the relation between rearing conditions and lifetime fitness in a long-lived shorebird, the oystercatcher (Haematopus ostralegus). We addressed specifically the relative contribution of ...
