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:
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.

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:
The ability of spatial expansion and conquering of new locations, suitable for growth, is one of the most important properties enabling different plant species (including forest trees) a permanent existence in a constantly changing (in space and in time) environment. In the course of evolution, plants developed several adaptations and mechanisms enabling them to capture new localities appropriate for life. The key role in this process is played by so called propagules, i.e. differently built spores, seeds and fruits. The main sources of forces and major transportation vectors for propagules are such mechanisms as: power of gravity (barochory), wind (anemochory), water (hydrochory), animals (zoochory) and man (antropochory). Among them, in case of tree species producing large seeds, containing bulky amounts of food resources, the most important role is played by zoochory. The special variant of zoochory is ornitochory, i.e. dispersion of plant propagules by birds. One of the best known and documented examples of ornitochory is dispersal of oak acorns by jays (Garrulus glandarius). The contemporary research shows that during a vegetation period one single bird is able to deposit even several thousends of acorns within the area of 10 to 100 ha. The dispersal distance in case of acorns distributed by jays is variable and depends on several factors, first of all, climatic conditions and degree of environmental heterogeneity. On average, acorns are distributed within a distance of several hundred meters from seed trees; sometimes they are disseminated at a distance of several (4−8, maximum 20) kilometers. As a rule, only a part of deposited acorns is uncovered and consumed by birds, thus at least some of them can germinate and produce new oak seedlings. It was also recently demonstrated that jays preferably put down acorns under the stand canopies composed by tree species other than oak, for instance, under Scots pine trees. Under favourable conditions, this initiates natural successional processes and leads to a significant conversion of tree stand composition. Considering a large scale and commonness of this phenomenon, it deserves an interest and attention, not in the case of natural forests only, but in the case of managed forests as well, in which the quasi−natural, successional processes, initiated by jays, can considerably contribute to a greater compositional and structural diversity of tree stands.

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:
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.

Thomas Jay Oord
Opis:
For the God of self-giving, kenotically-donated love, the decision to express love at all times comes first. In my conception, “full-Oorded” love would encompass what is ordinarily contained within the definition of agape love, but it would also include “eros love”, for the latter is the love of co-laborment. In my appropriation has of this terminology of eros love, it would be the type of love that the desires to, e.g., expand one’s territory or one’s domain, which makes it applicable to the modern theory of evolution by natural selection. Evolution – i.e., “descent with modification”, to invoke a Darwinian phrase – then, recognizes self-giving love, and the goodness thereof, in that species regularly undergo commensalist symbiotic relationships in nature, whereby one is aided by the other, while the “other” is neither “aided” nor “harmed”. This is self-giving love in its entirety, and a proper demonstration of it. My understanding of necessarily-expressed, “full-Oorded” love also includes dimensions of philia love. Philia could be akin to the symbiotic relationship known as mutualism in biology, especially since philia love has historically been associated with friendship or the interrelatedness of the natural world. Notably, Aristotle indicates that even nonhuman animals can express philia love . The relationships marked by philia, then, could be identified by mutuality, reciprocity, and cooperation , which fits the above biological connotation well. While agape or eros might benefit from cooperation, reciprocity, and mutuality, those two forms of love do not require any of those three nouns. Philia does. I contend, in fact, that the kenosis of the Spirit into creation amounts to self-giving, betrothed love through self-donation. The union, then of agape, eros, and philia love could be expressed as mutual aid, or full-orbed, or even as I like to say, “full-Oorded” love. Flourishing lives – be they human or some other mammal – I aver, consistently and necessarily express “full-Oorded” love. Oord suggests that Process philosophy can aid one to see that full-orbed love – that which I have designated “full-Oorded” love – plays an important part in the work to increase the common good of society as a whole. Indeed, “full-Oorded” love would repay evil with good as agape would; such a “full-Oorded” love would additionally welcome the intrinsic value and beauty in others, just like eros love does; and “full-Oorded” love would also recognize the import of friendship and mutuality as does philia love. Following Oord and Wojtyla again, since God commands that we show necessarily “self-giving”, “self-donating” love, we therefore indeed have the ability to love others as kenotically-donating entities, just as the creating Spirit does. When we act as a genuine conduit and amplifier of the creating Spirit’s self-donating and self-giving love, we can truly and entirely and infinitely love others, just as God does. Of course, we cannot expect that we humans will always love alike unto how God does because we do not have an eternal and unchanging nature that is necessarily inclined toward love , but we are at least always able to do it.

Opis:
W artykule przedstawiam pewien całościowy pogląd na kryzys, nawiązując do punktualizmu ewolucyjnego Stephena Goulda oraz dokonując jego filozoficznej ekstrapolacji: począwszy od dynamicznych ujęć metafizycznych, poprzez ewolucję kosmosu, aż do ewolucji biosfery (podobnie ujętą historię ludzkości zamierzam zaprezentować w kolejnym artykule). Twierdzę, że ewolucja na różnych poziomach bytu zachodzi w podobnym „rytmie”. W fazie pierwszej obiekt (struktura) znajduje się w stanie względnej równowagi i powolnych (gradualistycznych) przemian. Fazę tę kończy katastrofa, jakieś nagłe zdarzenie (zewnętrzne uderzenie albo wewnętrzne „pęknięcie), rozpoczynając fazę gwałtownych przemian, którą można określić jako kryzys sensu largo. Owe gwałtowne przemiany narastają aż osiągają moment krytyczny, moment kulminacji i przesilenia, który można nazwać kryzysem sensu stricto. Po tym kryzysie albo ma miejsce rozpad danego obiektu („śmierć”), albo przetrwanie, ale obiektu już wyraźnie zmienionego. Pojawia się nowa jakość (nowa całość), która przechodzi ponownie w stan względnej równowagi i powolnych przemian. Wskazuję też na opór, jaki wzbudzała – wśród filozofów, astronomów oraz przyrodników – dynamiczna wizja bytu, sugerując jednocześnie, że owa sympatia do stałości jest jedną z odmian idoli plemiennych Bacona.
In diesem Artikel stelle ich eine gewisse ganzheitliche Sicht der Krise vor, indem ich mich auf Stephen Goulds evolutionären Punktualismus beziehe und ihn philosophisch extrapoliere: von dynamischen metaphysischen Darstellungen über die Evolution des Kosmos bis hin zur Evolution der Biosphäre (ich beabsichtige, in einem späteren Artikel eine ähnlich gerahmte Geschichte der Menschheit darzustellen). Ich behaupte, dass die Evolution auf den verschiedenen Ebenen des Seins in einem ähnlichen "Rhythmus" verläuft. In der ersten Phase befindet sich das Objekt (die Struktur) in einem Zustand des relativen Gleichgewichts und der langsamen (graduellen) Veränderung. Diese Phase endet mit einer Katastrophe, einem plötzlichen Ereignis (einem äußeren Aufprall oder einem inneren "Bruch"), das eine Phase gewaltsamer Transformationen einleitet, die als Krise sensu largo beschrieben werden kann. Diese gewalttätigen Transformationen steigern sich, bis sie einen kritischen Moment erreichen, einen Moment des Höhepunkts und des Übergangs, der als Krise sensu stricto bezeichnet werden kann. Auf diese Krise folgt entweder der Zerfall des betreffenden Objekts ("Tod") oder sein Fortbestehen, allerdings in einem deutlich veränderten Zustand. Es entsteht eine neue Qualität (ein neues Ganzes), das wieder in einen Zustand des relativen Gleichgewichts und der langsamen Transformation übergeht. Ich weise auch auf den Widerstand hin, den die dynamische Vision des Seins bei Philosophen, Astronomen und Naturwissenschaftlern hervorgerufen hat, und behaupte, dass diese Sympathie für die Fixierung eine der Varianten von Bacons Idolen des Stammes ist.
In this article, I present a holistic view of a crisis, referring to Gould’s concept of “punctuated equilibrium” and making its philosophical extrapolation: from dynamic metaphysical approaches, through the evolution of cosmos, to the evolution of the biosphere (in the next article, I intend to present a similarly framed history of mankind). I argue that evolution on different levels of being occurs in a similar “rhythm.” In the first phase, the object (structure) is in a state of relative balance and slow (gradual) changes. This phase ends with a catastrophe, some sudden event (an external blow or an internal “rupture”), initiating a phase of rapid change that can be described as a crisis in the broad sense. These violent transformations grow until they reach a critical moment, a moment of culmination and solstice, which can be called a crisis in the strict sense. After this crisis, there is either the disintegration of the object (“death”), or the survival, but of the object already clearly changed. A new quality (a new whole) appears, which returns to a state of relative balance and slow changes. I also point to the resistance that such a dynamic vision of being elicited from philosophers, astronomers, and naturalists, suggesting that this sympathy for constancy is a variety of Baconian tribal idols.
