With up to 300 million receptors, a dog's nose is incredibly sensitive. Dogs can help in tasks such as detecting cancer or narcotics. This book showcases various working dogs, including dogs which were being trained for distinguishing between the native Eurasian and the invasive North American beaver in Finland. Please note, this resource is not open-access.

This article discussed various pests like flies, lice, fleas, and bugs: their impact on animal health and methods for control. It emphasised early detection and integrated pest management. The text describes how both species of modern-day beaver host a type of parasite called the 'beaver beetle.'

This report is a very visual scientific summary of the Devon Beaver Project. It looks at how the reintroduction of beavers has influenced the landscape, water quality, as well as local flora and fauna. The beavers helped, amongst other things, to mitigate agricultural water pollution.

This study in the USA examined the weekly diet of wolves from late June to early October by following a single pack and analysing their poo! The wolves' diet was varied and beavers made up a smaller proportion of their diet than anticipated. The text discussed why this might be the case, taking into account the availability of other prey and the times of year when beavers are most vulnerable to predation.

In this document, scientists showed how thermal imaging can help confirm the presence of active beaver colonies. However, pre-existing survey methods, such as tracking, led to different results. The text discussed how best to use this thermal imaging method for surveying beaver colonies. In Figure 1, it also shows what a beaver lodge looks like in a thermal image!
