We argue that ecology in general and biodiversity and ecosystem function research in particular need an understanding of functions which is both ahistorical and evolutionarily grounded. A natural candidate in this context is Bigelow and Pargetter’s evolutionary forward-looking account which, like the causal role account, assigns functions to parts of integrated systems regardless of their past history, but supplements this with an evolutionary dimension that relates functions to their bearers’ ability to thrive and perpetuate themselves. While Bigelow and Pargetter’s account (...) focused on functional organization at the level of organisms, we argue that such an account can be extended to functional organization at the community and ecosystem levels in a way that broadens the scope of the reconciliation between ecosystem ecology and evolutionary biology envisioned by many BEF researchers. By linking an evolutionary forward-looking account of functions to the persistence-based understanding of evolution defended by Bouchard and others, and to the theoretical research on complex adaptive systems, we argue that ecosystems, by forming more or less resilient assemblages, can evolve even while they do not reproduce and form lineages. We thus propose a Persistence Enhancing Propensity account of role functions in ecology to account for this overlap of evolutionary and ecological processes. (shrink)

Functional language is ubiquitous in ecology, mainly in the researches about biodiversity and ecosystem function. However, it has not been adequately investigated by ecologists or philosophers of ecology. In the contemporary philosophy of ecology we can recognize a kind of implicit consensus about this issue: while the etiological approaches cannot offer a good concept of function in ecology, Cummins’ systemic approach can. Here we propose to go beyond this implicit consensus, because we think these approaches are not adequate for ecology. (...) We argue that a sound epistemological framework to function in ecology is to be found in organizational approaches. In this line, we define function in ecology as a precise effect of a given constraint on the ecosystem flow of matter and energy performed by a given item of biodiversity, within a closure of constraints. We elaborate on this definition by developing a case study of a bromeliad ecosystem. (shrink)

Since 1974 Belgian traditional sectors have been facing important financial difficulties, which compelled them to seek both increased productivity through more capital intensive techniques, and goods with higher valued added.This twofold evolution implied investments and job-reductions that could hardly have been possible without adequate public policies. As far as steel and textile are concerned those policies used mainly a common scheme based on public financial intervention and social measures. Public financial support required to cover annual losses and investments consisted of (...) either grants or state equities. It amounted to over 200 billions BEF.Besides, policies were designed in favour of people losing their jobs : early retirement was made possible and was even accompanied with tax cuts. However the budgetary cost of those policies is very high, they may be considered successful as Belgian producers now seem able to stand unternational competition. (shrink)

This article on the evolution of economic and monetary policy in Belgium, which turned the "sick man of Europe" into one of the stronger European economies and allowed it to enter into EMU, stresses the role of the monetary authorities as a stabilising force in Belgium. It gives a detailed analysis of how these changes have allowed Belgium to regain the confidence of both monetary authorities and international investors after the devaluation of 1982. The policy responses to the oil shock (...) at the beginning of the seventies broke with the policy mix which had until then been practised. Both the wage formation process andf iscal policy clearly spiralled out of control, the chiefresult of which was a drastic loss in international competitiveness. As a consequence, the current account showed a large deficit, the traditional level at which public deficit had stood rose dramatically, unemployment exploded and the financial structure of most corporations became fragile.A drastic realignment of economic policy started with the devaluation of the Belgian franc in 1982. This devaluation was accompanied by a series of measures aimed at preventing the inflationary pressures from triggering further devaluations, and hence at restoring credibility. These measures included restrictive fiscal policies and real wage cuts. By 1987 this recovery policy had successfully restored Belgian competitiveness, reduced the government deficit and restored the balance ofpayments equilibrium. Although public policies became less restrictive during the period 1988-1993, the central bank continued to gain international credibility. Significant stepsin this process were the abolition of the dual exchange rate system, the decision to peg the Belgian franc to the most stable currency in the ERM and the reform of the money markets in Belgium. The latter in particular helped to increase the central bank's independence, since this reform implied total control by the central bank over short term interest rates, it reduced significantly the automatic credit lines of the fiscal authorities with the central bank and it stipulated that revaluations of gold reserves should no langer be used to finance government budget deficits. By 1992 international credibility had been restored to such a degree that the Belgian franc became a strong currency during the 1992 crisis, obliging the central bank to come to the rescue of the weaker currencies under attack in September 1992 with a speculative inflow of capital of about 200 billion BEF. However this restored credibility continued to be fragile, as became evident during the 1993 exchange rate crisis when the Belgian franc was vigorously attacked by international speculation.The insufficient alignment of public and monetary policies proved to be at the heart of the financial problems of the 1993 crises. The Belgian government relaunched its policies of budgetary restriction and wage moderation, brought together in what was called the 'Global Plan'. This realignment of public policies to monetary policy swiftly restored the credibility of the Belgian franc, so that as early as January 1994 the Belgian franc converged to its central parity with an interest differential vis-à-vis the German mark of only about 2 %. This differential declined progressively. Indeed the global plan restored the confidence of the investors in Belgian economic policy. Financial markets now fully believed in the entry of Belgium into EMU and from then on no major difficulties were to arise. (shrink)

This paper explores interactions between ecological science and conservation values in the biodiversity-ecosystem function debate of the 1990–2000s. The scientific debate concerned the interpretation of observed correlations between species richness and ecosystem properties like primary productivity in experimental ecosystems. The debate over the causal or explanatory role of species richness was presumed to have implications for conservation policy, and the use of such research to support policy recommendations generated hostility between rival groups of ecologists. I argue that the debate was (...) due in part to the adoption of a broad conception of biodiversity as a goal and value in conservation politics and ethical debates, and the ecologists who questioned the causal efficacy of species richness were also suggesting problems with this goal. I characterize what I call the “uneasy consensus” established by BEF researchers in the late 2000s, discuss roles for values in BEF research, and suggest that this episode shows that ecological science can itself be an important site for ethical debates about conservation values.

Because of an incomplete description of its contents, it has escaped notice that the fifteenth-century vellum MS Parisinus graecus 2833 contains Orphic Hymns 76 and 77 on folio 91 verso. The Hymns are copied, without indication of title or authorship, after Musaeus' Hero and Leander , and before the collected Prolegomena to Hesiod A a, b, c, BEF a, b Pertusi, which are followed by Hesiod's Works and Days, Shield and Theogony. These are all in the same hand.
