Oyster reefs were once abundant in European waters, but they are now rare. In Zeeland, the wild population of the native flat oyster (Ostrea edulis) has declined significantly in recent decades, with serious implications for coastal water health in relation to biodiversity and water quality (Colsoul …

This thesis examines how oil palm plantation characteristics affect the presence and biomass of earthworms in Malaysia. The research was carried out across 228 plots in Selangor and Negeri Sembilan. Results show that industrial plantations host more earthworms, while smallholder plantations support heavier …

The Netherlands is dependent on artificial structures for water safety. In addition to water safety the artificial structures also provide habitat for different aquatic species. When designing artificial structures like dikes and breakwaters adjustments can be taken to increase species richness or stimulate …

Climate change negatively impacts forests in terms of reduced vitality, productivity loss and sometimes even die-back (Allen et al., 2010). In Europe, these impacts are magnified by the species-poor, even-aged characteristics of many contemporary forests. To combat these effects, mixed-species forest …

Anthropogenic influences in the form of recreation and logging activities cause disturbance to the presence of birds in nature areas. Nature reserve Zompo lo Schioppo is an area with a high potential of biodiversity but where also recreation and logging are strongly facilitated. Therefore, it is important …

Contemporary European forests are devastated by severe forest fires. The probability of forest fires is only grow ing due to climate change. Forest managers are therefore transforming the forests into species rich forests resilient to the impacts of climate change. These forests are also referred to …

Within the middle hills of Nepal, OPs were found to prescribe the same operations, irrespective of species composition, forest conditions, and forest management objectives. The OPs play little, if any, role in practical forest management. The combined use of remote sensing and GIS technologies can be …

Pollinator biodiversity has decreased in the past decades, but urban areas have increasingly been found to serve as a refuge when compared to the surrounding intensively managed farmland. This offers an opportunity for urban pollinator conservation to play a role in the conservation of pollinators. But …

Currently a worldwide biodiversity crisis is going on and a sixth mass extinction seems to be approaching, because of human actions more than 10.000 species are currently on the brink of extinction (Tilman, Clark, & Williams, 2017). Acting on this crisis is therefore important and restoring biodiversity …
