1. Oyster reefs are among the most threatened marine habitats globally. In Europe, oyster reefs have been extirpated from most locations within their historical range. Active restoration of the native oyster (Ostrea edulis) in Europe has grown substantially in recent years. In sharing experiences between oyster restoration projects in Europe at the...

Flat oyster (Ostrea edulis L.) beds were once a dominant habitat type in the Dutch Delta and North Sea, but overharvesting resulted in soft sediment habitats devoid of oysters. Natural recovery of oyster beds will be slow if the natural substrate is lost and therefore, many oyster restoration projects have been set up worldwide. One way to enhance...

The Dutch government has the ambition to realise 3,5 GW in offshore wind farms before 2023. Longer term outlooks estimate 35 to 75 GW for 2050. This would result in the construction of 5,000 wind turbines in the Dutch North Sea. The introduction of artificial hard substrates by placing wind turbine foundations and scour protection facilitates epibe...

Article
Full-text available
For the recovery of flat oyster beds, knowledge is required of the conditions under which the active restoration of this species in the North Sea can be successfully implemented. This is the subject of the current feasibility study. Living flat oysters have occasionally been found in wind farms. Flat oyster growth has also been demonstrated experim...

In spring, large numbers of migrating Broad-billed Sandpipers make a stop-over in the Sivash, a shallow lagoon system in the Crimea, Ukraine, between the Black Sea and the Sea of Azov. Observed fuelling rates are high and, in just a few weeks, the birds can build up sufficient departure mass to reach their breeding grounds in a single non-stop flig...

Van 1992 tot 1995 is in het kader van het Botswana Swallow Project onderzoek gedaan naar de overleving van boerenzwaluwen in hun overwinteringsgebied in Botswana. Door de grote jaarlijkse verschillen in neerslag was het mogelijk het effect van neerslag op de conditie en rui van adulte en juveniele boerenzwaluwen, en daarmee op de overleving, te bes...

Article
A proximate, biophysical model is proposed describing temperature-modulated variation in growth rate and differentiation rate in ectotherms, based upon the Sharpe-Schoolfield equation connecting enzyme kinetics and biological rates. Like the Sharpe-Schoolfield equation, the model assumes (1) that growth rate and differentiation rate can be describe...

Article
In a population of the monogynous slave-making ant Harpagoxenus sublaevis in S.E. Sweden, the mean proportion of dry weight investment in queens was 0.54. This result differed significantly from 0.75 but not from 0.5, matching the prediction from the genetic relatedness hypothesis of sex ratio applied to slave-makers, given (as confirmed by this st...
