Bivalve ecology

Coexistence of the native mussel, *Mytilus edulis*, and the invasive Pacific oyster, *Crassostrea *(*Magallana*) *gigas*, does not affect their growth or mortality, but reduces condition of both species

Ecological impacts caused by invasive alien species can be severe but may vary depending upon environmental conditions. Many European populations of the native mussel, *Mytilus edulis*, have been invaded by the Pacific oyster, *Crassostrea* …

A first record of intertidal *Ostrea edulis* 3D structural matrices in Strangford Lough Northern Ireland - An emergent reef?

The European flat oyster *Ostrea edulis* once settled in high densities throughout its natural range but now exists only in small fragmented populations. In the Sea Lough of Strangford, Northern Ireland, recent increases in intertidal oyster numbers …

Lack of biotic resistance to an invasive bivalve irrespective of season or hydrodynamic disturbance

Coastal ecosystems are subject to a wide variety of abiotic variation including seasonal fluctuations and hydrodynamic disturbance, which can influence species distributions. Additionally, introductions of invasive species are creating biotic …

Wild gregarious settlements of Ostrea edulis in a semi‐enclosed sea lough: a case study for unassisted restoration

Ostrea edulis was once prolific throughout Europe and considered as the continent's native oyster. However, O. edulis currently exists in small fragmented assemblages where natural unaided recovery is rarely encountered. This research identified the …

Relative impacts of the invasive Pacific oyster, *Crassostrea gigas*, over the native mussel, *Mytilus edulis*, are mediated by flow velocity and food concentration

The ecological impacts of invasive species can be severe, but are generally viewed as highly unpredictable. Recent methods combining per capita feeding rates, population abundances and environmental contexts have shown great utility in predicting …

Using functional responses and prey switching to quantify invasion success of the Pacific oyster, Crassostrea gigas

Invasive alien species continue to proliferate and cause severe ecological impacts. Functional responses (FRs) have shown excellent utility in predicting invasive predator success, however, their use in predicting invasive prey success is limited. …
