How birds' beaks evolved characteristic shapes to eat different food is a classic example of evolution by natural selection. However, new research found this does not apply to all species, and that raptors in particular have not enjoyed this evolutionary flexibility.
Scientists have determined that a plant protein involved in the timing of flowering could in fact be a prion. This is the first time that a possible prion has been identified in plants, and it may play a role in a plant's 'memory' of cold exposure during winter.
A research team is studying the Atlantic brant goose in Canada’s Hudson Bay region. The bird's population has been on a moderate decline, and the team is looking to seen if limitations during the summer breeding season have accelerated that trend.
