What physical impact do water voles' burrowing activities have on riverbank soil composition and regulation?
Answer
Their burrowing helps to dry out the soil and promotes microbial activity that assists in regulating nitrogen levels
The creation of complex burrows, often featuring critical underwater entrances for escape, has significant physical and biochemical consequences for the riverbank environment. This digging action aerates the soil matrix, which contributes to drying out overly saturated areas. More importantly, this environment change stimulates specific microbial communities. These microbes are essential because they actively participate in regulating the nitrogen levels within the riverbank soil, suggesting that the physical structure created by the voles is intrinsically linked to the chemical health of their habitat.
