This paper compares the boom-bust cycle in Finland and Sweden 1984-1995 with the average boom-bust pattern in industrialized countries as calculated from an international sample for the period 1970-2002. Two clear conclusions emerge. First, the Finnish-Swedish experience is much more volatile than the average boom-bust pattern. This holds for virtually every time series examined. Second, the bust and the recovery in the two Nordic countries differ markedly more from the international pattern than the boom phase does. The bust is considerably deeper and the recovery comes earlier and is more rapid. We explain the highly volatile character of the Finnish and Swedish boom-bust episode by the design of economic policies in the 1980s and 1990s. The boom-bust cycle in Finland and Sweden 1984-1995 was driven by financial liberalization and a hard currency policy, causing large pro-cyclical swings in the real rate of interest transmitted via the financial sector into the real sector and then into the public finances.

The Åland Islands archipelago enjoys a special international status sui generis, which essentially encompasses demilitarisation, neutralisation, and autonomy. This status is guaranteed under international law by the agreements of 1921, 1940, and 1947, which are still in force. Furthermore, there are convincing reasons to assume that the Åland Islands regime has grown into European customary law. By virtue of her international (treaty) obligations, Finland cannot unilaterally change this status under the present conditions, irrespective of domestic (constitutional) decisions. While integration into NATO’s collective defence system and the EU’s Common Security and Defence Policy structures is compatible with the special status of the Åland Islands, care must be taken by Finland and her partners to ensure that the obligations arising from these developments are fulfilled in accordance with the demilitarised and neutralised status of the archipelago. This includes that the use by Finnish troops for preventive defence, beyond the exceptions laid down in the 1921 Åland Agreement, is only permitted in the case (of threat) of an immediate and clearly identifiable attack.
The autonomous character of the Åland Islands was established under a League of Nations dispute settlement and implemented, inter alia, in Finnish legislation. Its essence even grew into customary law. The arrangements of 1921, however, do not constitute a bilateral treaty between Finland and Sweden. The UN assumes that the international mechanism to protect Åland’s autonomy did not become obsolete with the demise of the League of Nations, but was only “suspended until such time as an express decision has been taken by the United Nations to put it back into force”. A corresponding proposal could be submitted, in any case, both by Finland and/or Sweden or possibly even by any other UN member state, for discussion in the Sixth Committee. However, the final decision to re-activate this special mechanism would have to be adopted by the UN General Assembly.
EU Law applies to the Åland Islands in principle; however, Finland’s Accession Treaty to the EU to which Protocol No. 2 on the Åland Islands was annexed, established a number of specific rules which are still in force today. This, most notably, results in the limited application of value added tax and excise duties in the Åland Islands. Therefore, the rules on customs procedures apply with respect to the movement of goods to and from the Åland Islands. In addition, other provisions of Union law, in particular those relating to fundamental freedoms and European state aid law, may be relevant in view of the special fiscal status of the Åland Islands. However, assessing individual cases would require further information and in-depth studies. Irrespective of the requirements set out in the said Protocol, the EU is obliged to respect the national identity of Member States pursuant to Article 4 para. 2 TEU; this obligation includes respect for the special status of the Åland Islands under both international and Finnish constitutional law.
In the literature, various environmental factors are described as being capable of influencing the reproductive output of insect females irrespective of their body size. Still, female body size or weight is widely used as a proxy for fecundity. In the present study, a seven-year data set on the autumnal moth, Epirrita autumnata (Borkhausen) (Lepidoptera: Geometridae), was used to analyze whether the body weight-fecundity relationship in this capital breeding, cyclic forest defoliating lepidopteran is constant across years. Ambient temperature conditions and density of conspecifics during larval development, the length of the pupal period, as well as moth densities in the parent generation were examined as factors capable of modifying the body weight-fecundity relationship. While the regression slope of potential fecundity (total egg numbers per female) on pupal mass was constant across years, the mean total egg number per given body weight (the regression intercept) was significantly different between years. This residual variance in egg numbers after controlling for the effect of pupal mass was best explained by the pooled geometrid density (autumnal and winter moths) in the parent generation. The total egg number per given body weight decreased with increasing density of geometrid moths in the parent generation. Thus, maternal density effects on offspring fecundity were found in this system. Their rather weak nature suggests, however, that this maternal effect alone does not have the potential of causing cyclic population dynamics in the autumnal moth.
Among cyclic populations of herbivores, inter-specific temporal synchrony has been attributed to both climatic factors and trophic interactions. In northern Europe, winter and autumnal moths undergo regular 9–11 year population cycles. The winter moth cycle has typically been phase-locked with that of the autumnal moth, but with a 1–3- year phase lag. We examined potential effects of natural enemies on this phase lag using field experiments and observational data. We found that larval parasitism was significantly higher in autumnal than in winter moths. Conversely, pupal predation by generalist invertebrates was clearly greater in winter than in autumnal moths. The difference in parasitism rates may contribute to the earlier collapse of the autumnal moth cycle. In addition, the phase lag may be strengthened by higher pupal mortality in winter moths in the early increase phase of the cycles. As a consequence, we put forward a hypothesis on reversed effects of natural enemies, providing a potential explanation for phase-lagged population cycles of these moth species.
1. Generalist natural enemies are usually not considered as being capable of causing population cycles in forest insects, but they may influence the population dynamics of their prey in the low density cycle phase when specialist enemies are largely absent. 2. In the present field study, the total response of the generalist invertebrate predator community to experimentally established pupal densities of the closely related autumnal (Epirrita autumnata) and winter moths (Operophtera brumata) was analysed. 3. Due to the high amount of variation in the dataset, the exact shape of the response curve could not be convincingly estimated. Nevertheless, two important conclusions can be drawn from the analyses. 4. Firstly, the natural invertebrate predator community seems to become saturated at rather low densities of both autumnal and winter moth pupae. Secondly, the predator community seems to become saturated at much lower densities of autumnal than of winter moth pupae. 5. Furthermore, pupal mass was significantly negatively correlated with invertebrate predation probability in autumnal moth pupae. 6. These results indicate that differences in the predator assemblage being able to consume pupae of the two moth species, as well as different handling times, could be responsible for the substantially higher predation rates in winter than in autumnal moth pupae. 7. As a consequence, the population dynamics of autumnal moths might be less affected by generalist invertebrate predators than those of winter moths, as autumnal moths seem able to escape from the regulating influence of generalist predators at much lower population densities than winter moths.
An inventory of Sciaridae (Diptera: Sciaroidea) from a eutrophic fen and a spring brook in Viidumäe Nature Reserve (Estonia, Saaremaa Island) recorded a total of 60 species, of which 57 are new records for Estonia, including two that are new to science and described herein as Cratyna (Diversicratyna) palustricola sp. nov. (Estonia) and Sciara bryophila sp. nov. (Estonia, Finland). This has raised the number of Sciaridae known from Estonia from 6 to 63.
One of the unresolved questions in studies on population dynamics of forest Lepidoptera is why some populations at times reach outbreak densities, whereas others never do. Resolving this question is especially challenging if populations of the same species in different areas or of closely-related species in the same area are considered. The present study focused on three closely-related geometrid moth species, autumnal Epirrita autumnata, winter Operophtera brumata and northern winter moths Operophtera fagata, in southern Finland. There, winter and northern winter moth populations can reach outbreak densities, whereas autumnal moth densities stay relatively low. We tested the hypothesis that a lower vulnerability to pupal predation may explain the observed differences in population dynamics. The results obtained do not support this hypothesis because pupal predation probabilities were not significantly different between the two genera within or without the Operophtera outbreak area or in years with or without a current Operophtera outbreak. Overall, pupal predation was even higher in winter and northern winter moths than in autumnal moths. Differences in larval predation and parasitism, as well as in the reproductive capacities of the species, might be other candidates.
1. Both direct and indirect competition can have profound effects on species abundance and expansion rates, especially for a species trying to strengthen a foothold in new areas, such as the winter moth (Operophtera brumata) currently in northernmost Finland. There, winter moths have overlapping outbreak ranges with autumnal moths (Epirrita autumnata), who also share the same host, the mountain birch (Betula pubescens ssp. czerepanovii). Competitive interactions are also possible, but so far unstudied, are explanations for the observed 1–3 years phase lag between the population cycles of the two moth species. 2. In two field experiments, we studied host plant-mediated indirect inter-specific competition and direct interference/exploitation competition between autumnal and winter moths. The experimental larvae were grown either with the competing species or with the same number of conspecifics until pupation. Inter-specific competition was judged from differences in pupal mass (reflecting lifespan fecundity), larval development time and larval survival. 3. Larval performance measurements suggested that neither direct nor indirect interspecific competition with the autumnal moth reduce the growth rate of winter moth populations. Winter moths even had a higher probability of survival when reared together with autumnal moths. 4. Thus, we conclude that neither direct nor indirect inter-specific competition is capable of suppressing the spread of the winter moth outbreak range and that both are also an unlikely cause for the phase lag between the phase-locked population cycles of the two moth species.
This is the eighth article in our series Trouble on the Far-Right.
Trouble’s brewing for the European Union – also in Finland, where the next country-wide elections will see several new, EU-hostile nationalist groups attempt to establish themselves on the political map. At the same time, Finnish Fascism is seeking to entrench and normalize itself into a respectable part of the political framework.
With disaffection growing, the time appears to be ripe. As Heikki Hiilamo, professor of social policy in Helsinki University notes, Finland has been particularly hard hit by the most recent economic downturn. The middle and lower classes are seeing their expectations fade into uncertainty, as globalization is bringing new and intangible threats in the form of vanishing jobs. Finland is heading towards increasing social inequality, with the reality of the educated and the employed drifting further apart from “globalization’s losers”. With no self-evident owner in sight, the accumulating political capital is attracting radical nationalist utilizers...
