The Cost of Servicing Greece’s Debt: A Sisyphean task? CEPS Commentary, 4 February 2015

Following the victory of Syriza in the Greek elections on January 25th, policy-makers, economists and concerned EU citizens are scrambling to understand the causes, modalities and consequences of a possible Greek default in order to anticipate and prepare for what is likely to unfold in the coming weeks and months. The debate on the sustainability of Greek public finances has often been characterised by a lack of clarity and even a certain degree of confusion. This brief note focuses first on the cost that Greece faces in servicing its debt and then asks whether this is a manageable or a Sisyphean task. It concludes by reflecting on the political implications of the new government’s announced intentions and whether these are being taken into account in the current debate over debt restructuring.

The association of feeding behavior with the resistance and tolerance to parasites in recently diverged sticklebacks

Divergent natural selection regimes can contribute to adaptive population divergence, but can be sensitive to human-mediated environmental change. Nutrient loading of aquatic ecosystems, for example, might modify selection pressures by altering the abundance and distribution of resources and the prevalence and infectivity of parasites. Here, we used a mesocosm experiment to test for interactive effects of nutrient loading and parasitism on host condition and feeding ecology. Specifically, we investigated whether the common fish parasite Gyrodactylus sp. differentially affected recently diverged lake and stream ecotypes of three-spined stickleback (Gasterosteus aculeatus). We found that the stream ecotype had a higher resistance to Gyrodactylus sp. infections than the lake ecotype, and that both ecotypes experienced a cost of parasitism, indicated by negative relationships between parasite load and both stomach fullness and body condition. Overall, our results suggest that in the early stages of adaptive population divergence of hosts, parasites can affect host resistance, body condition, and diet.
