Grand challenges in conservation

Conservation aims to protect rare species and preserve biodiversity. To do this effectively, we need to understand the factors that pose threats to species and ecosystems. Sometimes these may apply …

What is conservation?

Understanding the ecology of species is critical to informing our efforts for their preservation. Listen to Dr. Callum Macgregor discussing the many faces of conservation, from protecting single species to …

The importance of carbon to life

Life on earth would not be possible without carbon. This is in part due to carbon’s ability to readily form bonds with other atoms, giving flexibility to the form and …

Agriculture and nutrient cycling

What plants need Plants are made up mostly of carbon, oxygen and hydrogen, which they obtain from water and carbon dioxide. However, plants will take up a number of other …

How green is my valley?

What determines the diversity of an ecosystem; in other words, how many species are present within an area of habitat? Although this question sounds simple, it is actually very complicated …

What is biodiversity and why does it matter?

Understanding how to generate important evidence concerning the role of biodiversity with Dr. Callum Macgregor. In this video we think about what is meant by the term “biodiversity”. We discuss …

Activity: tracking tunnel

Tracking tunnel experiment Aims: Tracking tunnels are a non-invasive tool that ecologists can use to investigate the presence of mammals in a habitat by identifying their footprints. Tunnels can be …

Biology toolbox: modelling populations

Can we understand how populations change? With a million species at risk of extinction globally understanding how populations are changing, and why, is vital to help us develop effective conservation …

Populations

Understanding how organisms interact with members of the same species and others is key to implementing effective conservation strategies. In this video we consider why biologists want to study populations, …

Biology toolbox: ecological sampling

Whether we are wanting to estimate populations, sample dung or measure plant growth, the first challenge we need to overcome is to design an effective sampling regime. In the video …

Gorongosa’s landscape of fear

Rewilding is currently a hot topic in conservation in the UK. Rewilding seeks to return landscapes to a state where ecological processes function with little intervention from humans. The dream …
