The Cascadia margin, off the west coast of Vancouver Island, Canada, h…
With the progress of mantle convection modelling over the last decade, it now becomes possible to solve for the dynamics of the interior flow and the surface tectonics to first order. We show here that tectonic data (like surface kinematics and seafloor age distribution) and mantle convection models with plate-like behaviour can in principle be combined to reconstruct mantle c…
We revisit a methodology to gauge the short-term effect of price changes on smallholder farmer�s welfare that is popular amongst policy makers and academia. Realising that farmers face substantial seasonal price volatility over the course of an agricultural year, we pay particular attention to the timing of sales and purchases. In addition we depart from the implicit assumption that all …
Suction feeding is pervasive among aquatic vertebrates, and our understanding of the functional morphology and biomechanics of suction feeding has recently been advanced by combining experimental and modeling approaches. Key advances include the visualization of the patterns of flow in front of the mouth of a feeding fish, the measurement of pressure inside their mouth cavity, and the employmen…
Exogenous shocks to farmers� consumption, production and labour market decisions are rarely considered accurately. For farm households, under labour market imperfections, such decisions are often interlinked. This calls for non-separable agricultural household models. According to this framework, second-order (or behavioural) effects include a direct (i.e., supply or demand reactions due …
In the motorcycle-taxi market in most Sub-Saharan African countries, the relation between vehicle owner and driver is characterised by a principal-agent problem with the following features: the owner cannot observe the final output of the driver and therefore cannot condition awageonit, andhighereffort fromthedriverdepreciatesthemotorcycle.

This study investigates the relationship between family network density and income hiding in rural Liberia. We link people�s behaviour in a modified lottery experiment and a time preference game to detailed information about their family networks. We find that individuals with a dense family network are more likely to pay a fraction of their endowment to hide their earnings from the ex…
The increase in phenotypic variability through gene expression noise is proposed to be an evolutionary strategy in selective environments. Differences in promoter-mediated noise between Sac charomycescerevisiae strains could have been selected for thanks to the benefit conferred by gene expression heterogeneity in the stressful conditions, for instance, those experienced by industrial str…
Plant organisms contain a large number of genes belonging to numerous multigenic families whose evolution size reflects some functional constraints. Sequences from eight multigenic families, involved in biotic and abiotic responses, have been analyzed in Eucalyptus grandis and compared with A rabidopsisthaliana. Two transcription factor families APETALA2(AP2)/ethylene responsive factor an…
Viruses with single-stranded(ss) DNA genomes infect host sinall three domains of life and include many medically, ecologically, and economically important pathogens. Recently, a new group of ssDNA viruses with chimeric genomes has been discovered through viral meta genomics. These chimeric viruses combine capsid protein genes and replicative protein genes that, respectively, appear to have been…
