In the 1st IBO 22 students and 6 countries participated. Winners of the respective national competitions – their skills in trackling biological problems, and dealing with biological experiments are tested. The competition consists two parts – theoretical test and practical tasks, in 50:50 ratio. Coordination centre of IBO located in Prague, International Scientific Advisory Board (ISAB, now AB IBO), national coordinators and since 2008 also steering committee have been responsible for organization of the competition. In the last 30 years number of countries and students participated in the competition evidently increased. In 30th IBO, which was held in Hungary (Szeged) in 2019, 285 students and 72 countries of the world participated. In 2020 IBO was organized in distance/online form only caused by Covid 19 pandemic situation.

Rapid development of the field of ecology is evident since the end of last century and following decades of 21st century. The paper deals with current development, diversity of concepts and hypotheses, including critiques of invasion terminology, invasion species concepts, introduced species as bad species and xenophobe appeared related to aliens as invaders. Invasion biology was an attempt to integrate alien animals and plants research into one science. In last decade new science of invasions is developed, characterised by multi- and interdisicplinarity, supported by social and economy sciences. To facilitate generalisations, and to improve the link between science, policy, and management, numerous frameworks have been developed in an attempt to unify different concepts and definitions.

Forest Research Site at Bab near Nitra, SW Slovakia. Inputs, storage and losses of water into/in/from the deciduous broad-leaved forest stand are considered separately.
