<jats:p>Το πεδίο αυτής της διατριβής είναι η ιστορία της επιστήμης της Οικολογίας· πιο συγκεκριμένα, εστιάζει στην επιρροή που άσκησε η κυρίαρχη αστική ιδεολογία πάνω στην επιστήμη της Οικολογίας. Ξεκινάμε έτσι από την προδαρβινική ακόμα Φυσική Ιστορία, όπου κυριαρχούσε ήδη μία σειρά μεταφορών (προερχόμενων κυρίως από την αστική Πολιτική Οικονομία και φιλοσοφία) και αναπαραστάσεων, όπως η 'οικονομία της φύσης', ο 'καταμερισμός της εργασίας' το 'κοινό συμφέρον' και ο 'ατομικός ανταγωνισμός'. Τα στοιχεία αυτά προβάλανε στην προδαρβινική Φυσική Ιστορία τις κυρίαρχες ιδεολογικές αντιλήψεις για την αρμονία, την ενότητα και την τάξη του κόσμου. Παρά τη ρήξη που επέφερε με αυτή την προβληματική η εξελικτική θεωρία του Δαρβίνου, οι περισσότερες σχολές της πρώιμης οικολογίας ακολούθησαν μάλλον το παράδειγμα της προδαρβινικής αρμονίας, παρά της δαρβινικής εξέλιξης. Σε αυτό το υπόβαθρο, αναδύθηκε η έννοια της ποικιλότητας ειδών, μέσα από την αναζήτηση του κατάλληλου στατιστικού μοντέλου που θα προβλέπει μία σταθερή και επαναλαμβανόμενη κατανομή των ατόμων στα διάφορα είδη-μέλη μίας βιολογικής κοινότητας. Η χρήση της θα γενικευθεί τη δεκαετία του 1950, στο πλαίσιο της κυβερνητικής Οικολογίας, όπου η ποικιλότητα αναδεικνύεται αφενός σε κυβερνητικό μηχανισμό που εξασφαλίζει τη σταθερότητα μίας κοινότητας απέναντι στις εξωτερικές διαταραχές και αφετέρου σε φυσικό μέτρο της ετερογένειας, της ωριμότητας και του βαθμού διαταραχής μίας κοινότητας. Σταδιακά, και παρά την έντονη κριτική που δέχεται από εξελικτική κυρίως σκοπιά, η ποικιλότητα αναδύεται τελικά στο επίκεντρο της Οικολογίας και ιδιαίτερα των νέων ρευμάτων περιβαλλοντικής μηχανικής, αποτυπώνοντας τη δομή των οικολογικών σχηματισμών μέσα από έναν απλό αριθμό, κατάλληλο για σύγκριση και αξιολόγηση. Ανακεφαλαιώνοντας, καταλήγουμε ότι η έννοια της ποικιλότητας λειτούργησε ως ένας καθοριστικός κόμβος για την είσοδο ιδεολογικών μεταφορών εντός του επιστημονικού πεδίου της Οικολογίας και τελικά την εξάρτηση του τελευταίου, ιδιαίτερα με τη μορφή της περιβαλλοντικής διαχείρισης, από την κυρίαρχη ιδεολογία της εποχής μας. Η (βιο)ποικιλότητα αναδείχθηκε με αυτό τον τρόπο σε ένα ισχυρό ιδεολογικό σημείο διαρραφής του πεδίου της, αποτελώντας τον κεντρικό εκείνο καθορισμό που νοηματοδοτεί τις άλλες έννοιες, ενώ ταυτόχρονα η ίδια χάνει σταδιακά το όποιο συγκεκριμένο, επιστημονικό περιεχόμενό της. Παράλληλα με αυτή την πορεία, η Οικολογία στρέφεται συνολικά προς μία ποσοτική και προβλεπτική πρακτική, η οποία στοχεύει στην εκτίμηση των φυσικών ορίων που παρουσιάζουν τα φυσικά οικοσυστήματα απέναντι στις ανθρωπογενείς διαταραχές. Οι μαλθουσιανές αυτές ιδέες απομακρύνουν ακόμα περισσότερο την Οικολογία από την εξέλιξη, εστιάζουν το ενδιαφέρον μόνο σε ποσοτικά ζητήματα, ενώ λειτουργούν εξόχως πολιτικά και απολογητικά, απαλλάσσοντας τις κυρίαρχες κοινωνικές σχέσεις.</jats:p>

The field of this dissertation is the history of the science of Ecology; our specific object is the influence of the dominant bourgeois ideology upon the science of Ecology. We start from the pre-darwinian Natural History, which was already dominated by a series of metaphors (mainly originated in the bourgeois political economy and idealistic philosophy) and representations, such as the ‘natural economy’, the ‘division of labor’, the ‘common interest’ and the ‘individual competition’. These theoretical elements imposed upon pre-darwinian Natural History the dominant ideological conceptions about harmony, the unity, and the order of nature. Despite the evolutionary theory of Darwin, which came in contradiction with these ideological perceptions, most of the schools of the early Ecology followed the paradigm of pre-darwinian harmony, rather than that of Darwinian evolution. Within this theoretical context, the concept of species diversity has been emerged, through the quest for an app...

The representation of a complex but stable, self-regulated and, finally, harmonious nature penetrates the whole history of Ecology, thus contradicting the core of the Darwinian evolution. Originated in the pre-Darwinian Natural History, this representation defined theoretically the various schools of early ecology and, in the context of the cybernetic synthesis of the 1950s, it assumed a typical mathematical form on account of α positive correlation between species diversity and community stability. After 1960, these two aforementioned concepts and their positive correlation were proposed as environmental management tools, in the face of the ecological crisis arising at the time. In the early 1970s, and particularly after May’s evolutionary arguments, the consensus around this positive correlation collapsed for a while, only to be promptly restored for the purpose of attaching an ecological value on biodiversity. In this paper, we explore the history of the diversity–stability hypothesis and we review the successive terms that have been used to express community stability. We argue that this hypothesis has been motivated by the nodal ideological presuppositions of order and harmony and that the scientific developments in this field largely correspond to external social pressures. We conclude that the conflict about the diversity–stability relationship is in fact an ideological debate, referring mostly to the way we see nature and society rather than to an autonomous scientific question. From this point of view, we may understand why Ecology’s concepts and perceptions may decline and return again and again, forming a pluralistic scientific history.

The conflicts around the scientific status of the concept of diversity are considered here as symptoms of hidden, socially originated, ideological representations inherent in the theoretical context of western ecology. Species diversity was coined in the 1940s, as a constant in the statistical models that described the distribution of individuals into different species and, therefore, as the expression of all the parameters that determine ecologically this distribution. The assumption of such a regular distribution is attributed to the influence of organicism and the correlated presuppositions of harmony and homeostasis. Nevertheless, as species diversity was the only unknown parameter in these models, it reversed the direction of the functions and established itself as the main variable under question. After the 1950s, the concept of species diversity was empowered by the strong impact of cybernetics and systems theories; in this context, diversity was considered as a self-regulati...

After the 1950s, the concept of species diversity was empowered by the strong impact of cybernetics and systems theories; in this context, diversity was considered as a self-regulating mechanism that assures overall stability. Diversity emerges as a natural and one-dimensional measure of community complexity, maturity, and stability. In the perspective of the arising ecological crisis, diversity - because of its property to compare and evaluate - arises as the nodal point of the new scientific/ideological fields of nature conservation and ecosystem management.

Despite the mounting discussions on the concepts of diversity and biodiversity, no generally accepted definition has ever emerged, while many ecologists have argued that the concept of diversity lacks ecological meaning. The ambiguity of diversity is interpreted here as the result of hidden, socially originated, ideological representations within the scientific fields of ecology. Ideological representations are discerned since the first appearance of diversity indices in the early 1940’s. The index of diversity was first introduced in ecology as a simple statistical constant within the equations of species-individuals curves, expressing the equitability with which individuals are distributed into different species. Distribution models presuppose that individuals be distributed into different species in a regular, repeatable way that expresses the hidden, internal order of every biological community. This presupposition is attributed to the ideological influence of organicism, according to which biological communities used to be considered as stable, discernible, harmonically and hierarchically organized unities of members.
However, soon after their introduction, species-individuals equations were automatically reversed and diversity became the variable under question. Hence, the measurement of diversity arose as the central question and ecologists employed new methods and concepts from Statistics, Systematics and Information Theory in order to find appropriate indices of diversity. Diversity indices, as quantified expressions of biological complexity, embody an infinite series of material qualities -such as individuals, populations, species and interspecies relationships- which under the frame of a mathematical function are equalized as general equivalents. It will be argued that the emergence of diversity indices through a reification process is motivated by hidden ideological representations reflecting dominant socioeconomic practices.
After the 1950’s diversity indices were employed by the uprising field of Systems Ecology. Diversity was related to other important ecosystem’s properties, such as stability, productivity and efficiency. Under the premises of an arising ecological crisis, ecologists tried to establish a positive correlation between diversity and stability, due to an external, social pressure for appropriate criteria of ecosystem management. Nevertheless, through this socially motivated relation, the meaning of ecological stability is redefined as the lack of fluctuation, acquiring a cybernetic, quantified aspect. Similar arguments are held with regard to the relation between diversity and productivity or efficiency. Finally, a complex of correlated, quantified, measurable and manageable ecosystemic concepts is emerging from the older fields of community and ecosystem ecology, leading to the new unifying attempts of the late 1960’s and to the new scientific-political field of environmental management. In this process, diversity arises as the nodal point of its field, a concept that transforms and determines the meaning of all others, due to its socially originated power.
