Opis:
The paper is a brief description of the role of birds in forest tree seed dispersal by synzoochory and seed consumption, as well as ecological consequences of these phenomena. Special attention has been drawn to the way seeds are stored by birds or in other words if the seeds can survive and be able to germinate. An overview of the most recent world literature connected with this subject was presented. An attempt has been made to assess the role of seed – eating birds in the natural forest ecosystem.

Opis:
The aim of this paper is to show some aspects of the interplay between technology and philosophy in the context of western culture. In the first section the author considers the possibility of applying M. Heller's strategy called 'philosophy in science' to technology. 'Philosophy in technology' should not be seen as a competitor for philosophy of technology but rather as a complementary philosophical account. The second section introduces the concept of 'defining technology' drawn primarily on some considerations of J.D. Bolter. In the third one the author tries to discuss four 'defining technologies': craft technology of antiquity, mechanical clock, steam engine, computer, and their metaphorical influence on the ways of viewing the world and the man. In the final section it is argued that besides science, religion, philosophy, arts etc., technology also has its significant contribution to the image of the world throughout the history.

Opis:
There are many different approaches to the problem of the relation between science and religion. It is often claimed that there exists a conflict between those two domains. However, S. J. Gould cannot see neither how the two enterprises can stay in any conflict nor how they can be reconciled or unified. He developed a concept of two Non-Overlapping Magisteria (NOMA). Gould claims that science and religion are characterized by completely different areas of investigation. The two magisteria ask different questions and provide different explanations. Science investigates the factual character of the natural world while religion explores the world of values, meanings and purposes of human life. One could say that this is a reasonable point of view, but at a closer glance it does not seem to be a satisfactory solution.

Opis:
Artykuł przedstawia podstawy teorii przerywanej równowagi sformułowanej jako alternatywne względem gradualistycznego darwinizmu ujęcie przebiegu makroewolucji. Twórcami teorii przerywanej równowagi są amerykańscy paleontologowie Stephen Jay Gould i Niles Eldredge, według których proces makroewolucji nie zachodzi stopniowo, małymi kroczkami, lecz charakteryzuje się długimi okresami stazy, które co jakiś czas przerywane są szybkimi - w skali geologicznej - przemianami organizmów.
The article presents foundations of the theory of punctuated equilibrium which was formulated as an alternative account of the course of macroevolution to gradualistic Darwinism. Founders of the theory of punctuated equilibrium are American paleontologists Stephen Jay Gould and Niles Eldredge who claim that the process of macroevolution does not occur gradually, step by step, but it is characterized by long periods of stasis punctuated, from time to time, by rapid – on geological scale – transformations of organisms.

Opis:
In my response to Kowalski’s commentary I indicate that: 1) there is an imprecision in Kowalski’s presentation of the NOMA principle; 2) the NOMA principle is not a valid way of presenting theistic religions; 3) the argumentation adopted by Kowalski is inconsistent, due to inconsistency in the NOMA principle itself. The Kowalski’s cure for the “Confrontations Between Theists and Atheists” mentioned in the title of the Kowalski’s commentary is the postulate of a “miracle-free” theism, which means the elimination of theism. Another important weakness of Kowalski’s proposal and of the application of the NOMA principle in general is the self-contradictoriness of this position: when we decide on the truth value of this or that factual religious statement by reference to science, then we deny the essence of the NOMA principle itself.

Opis:
The aim of this study was to analyse the preferences of jays in terms of oak acorn deposition in accordance to availability of some types of habitat. Investigations were carried out in forested areas of the Olsztyn Lakeland (NE Poland) with Scots pine forests domination. In autumn of 2014 and 2015 122 acorns of Quercus robur with concealed Telenax transmitters were served in four locations and then dispersed by jays Garrulus glandarius. Acorns with transmitters were radio tracked and localized after dispersion in different types of habitats. We distinguished three types of habitat: forest stands >40 years old, young forests <25 years old as well as clear−cuts and other open areas. The availability of habitats were estimated by 144 random points (36 per each location). Obtained availability/utilisation data were analyzed with chi square test ( =0.05). Results showed that majority (76.4%) of dispersed acorns were deposited under canopy of Scots pine stands, while only 8.2% were deposited on clear−cuts and other open areas. It seems that jays avoid to scatter its caches among clear−cuts and other open areas when availability of these types of environment is compared. Jays preferred to scatter the acorns under canopy of older (>40 years old) stands. It proves that the regeneration of oaks in clear−cuts is with low probability of success. The results suggest that density and high quality of regeneration that occurred on some of the clear−cuts seem to be a synchronization relic of oaks' mast crop and Scots pine fellings. In these circumstances the best solution to obtain oak regeneration is to synchronize the harvest with mast crops and carry it out immediately after acorn production to make an oak regeneration success guaranteed.
