Tree of the year: Yew tree in Estonia and elsewhere
Lea Vaher describes the rarest of our domestic conifer species, and its use in Estonia and elsewhere in the world. The Irish yew tree, growing in its north-eastern edge of distribution in Estonia, is the most common among the 8-10 species of the world’s yews. It is an interesting relic species with extraordinary vitality and adaptability. The yew tree has remarkably slow growth and long life-time (up to 2000-4000 years). It is a poisonous tree all over and even a few berries can cause lethal results for humans as well as for cattle, especially for horses. The article gives a thorough and interesting overview of this little-known species.

Tatjana Krama’s dissertation created excitement in animal ecology: birds are very helpful not only towards their close relatives, but also towards other birds of the same species. The author has proved that mobbing – a joint attack against a predator that would not be attacked alone – is common among most small birds. The main thesis of the dissertation was to find out if birds act based on the reciprocal altruism model while mobbing, even if it can cost the bird its life. The article gives an overview of the experiments made and methods used within the study, and the exciting results regarding the mobbing behavior of small birds.
