Biodiversity and Natural Environment

Biodiversity refers to the variety of life forms within species, between species and within and between landscapes, ecosystems or the whole planet. Biodiversity can thus be described at the genetic, species or ecosystem level. For both theoretical and practical reasons biodiversity is measured as the number of taxa, and in particular of species. There are approximately 7-12 million species of which circa 1.9 million are described. Biodiversity is under pressure. It is generally assumed that a reduction of biodiversity is undesirable and should be prevented. Is the disappearance of species really undesirable and if so, can we counteract further deterioration of biodiversity?

In order to answer these questions we have to examine in more detail what biodiversity actually represents and how it can be mapped. In addition it is important to study how biodiversity evolved and which are the important processes that determine the level of biodiversity in today’s ecosystems. By analyzing the processes that take place in ecosystems we will investigate how biodiversity is threatened, for example as a result of human intervention or unintentional introduction of invasive species. We shall study how species decline is related to life-history traits. In addition we will investigate the impact of newly introduced species or genes on current biodiversity in the Netherlands.

Human intervention and the introduction of new species do not necessarily have only negative effects on biodiversity. It can also lead to “novel ecosystems” for example in urban and agricultural areas. Species can adapt and be successful in these new habitats. How we should value these new systems is a question of often heated debates. In this minor you will be challenged to take position on these matters.
