Human impacts on biodiversity

Project summary

  • Focus: to model the response of biodiversity to environmental changes caused by human activity
  • Funding: NERC

We are modelling environmental changes caused by human activity.

Human activities are causing major changes in biological communities worldwide. These changes can harm biodiversity and ecosystem function.

Ecosystem function is important for supporting plant and animal communities, and ensuring the long-term survival of human populations.

The main threats facing biodiversity globally are:

  • destruction, degradation and fragmentation of habitats
  • reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.

However, species do not all respond equally to these threats. Declines in species often reflect the relationships between species and ecological patterns.

There is an urgent need to model the response of biodiversity on the intensity of human activity and the species' ecological attributes.

By fully understanding how species respond to human activities we can make projections that inform policy.

Projects

PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems)

PREDICTS is a collaborative project that uses approaches similar to a meta-analyses to investigate how local biodiversity typically responds to human pressures, such as land-use change, pollution, invasive species and infrastructure.

We collate comparisons studies on species' abundance and use them to model inter-site biodiversity differences, including the effect of human activities on species' abundance.
