Freshwater ecosystems and their bordering wetlands and riparian zones are vital for human society and biological diversity. Yet, they are among the most degraded ecosystems, where sharp declines in biodiversity are driven by human activities, such as hydropower development, agriculture, forestry, and fisheries. Because freshwater ecosystems are cha...

Question Riparian vegetation and seed banks are the foundation of functional riparian zones, yet insight in the processes that explain their composition is limited. We tested three theories fundamental to dispersal and environmental filtering of riparian seed banks and vegetation. Combining these theories, we expected hydrochory to lead to increase...

Riparian zones are species-rich and functionally important ecotones that sustain physical, chemical and ecological balance of ecosystems. While scientific, governmental and public attention for riparian zones has increased over the past decades, knowledge on the effects of the majority of anthropogenic disturbances is still lacking. Given the incre...

This report examines how food forestry in the Netherlands has developed in recent years and which plant species are introduced. These plant species will be referred to as 'food forest species', but this does not mean that the planting of these species is limited exclusively to food forests. It has been analysed whether and to what extent alien food...

Agricultural intensification and abandonment of semi-natural grasslands lead to a decrease of habitat for insects. Apart from the loss of native species and overall biodiversity, important ecosystem services such as pollination of wild flowers and crops may come at risk. The aim of the present study in central Sweden was to test whether man-made ha...

The Indonesian island of Java has changed immensely over the past century and is expected to keep changing in the coming decades. Here, we investigated how land use has changed over the past 100 years and what possible effects this has had on the rich Javan avifauna. We focused on a transect within the highly populated area of the Citarum river bas...
