| Das Klima bestimmt entscheidend das Auftreten, die Ausbreitung und Entwicklung von Schadorganismen. Weil die Temperatur die Entwicklung von Insekten massgeblich steuert, ist durch die globale Er-wärmung mit einer steigenden Befallsgefährdung von Kulturpflanzen durch Schadinsekten zu rech-nen. Ausgehend von Klimaszenarien, Verbreitungsdaten und den bekannten Umweltansprüchen von Schadinsektenarten verwenden wir diverse Modellierungsansätze, um die Entwicklung und künftige Verbreitung ausgewählter, landwirtschaftlich relevanter Schadinsekten vorherzusagen. Die bearbeiteten Fallbeispiele umfassen sowohl in der Schweiz etablierte Arten, wie auch gebietsfremde Arten, welche erst kürzlich eingeschleppt wurden und solche, die in der Schweiz noch nicht vorkommen... |

| Temperature is a main climatic driver of plant phenology and the dominant abiotic factor directly affecting insect pests. Global warming is therefore expected to accelerate the development of plants and insects alike. In the case of multivoltine pest species, it was shown that higher temperatures lead to the appearance of additional generations toward the end of the warm season (Stöckli et al., 2012), which also has implications for pest management. The same effect was shown for the timing of flowering termination of apple trees (Stöckli and Samietz, 2015), the time when a pest can attack a fruit. In practice, however, much would depend on whether plant and pest phenology remain synchronized or not. Focusing on Switzerland, in this contribution we... |

| It is expected that the development of plants and insects will be accelerated by global warming, resulting in an earlier occurrence of phenological stages in the future as compared to today. For plants, this could lead to a higher exposure to climatic shocks (late frosts in spring, and critical high temperatures in summer) and changes in the incidence of insect pests. Assessing the implications of such shifts in phenology is important to be able to devise, where necessary, means for reducing biotic and abiotic risks in plant production. In this contribution we present an analysis of the potential impacts of climate change on the risk of late frost and damages to fruits caused by critically high temperatures in apple orchards across Switzerland. We further... |

| The static chamber approach is often used for greenhouse gas (GHG) flux measurements, whereby the flux is deduced from the increase of species concentration after closing the chamber. Since this increase changes diffusion gradients between chamber air and soil air, a nonlinear increase is expected. Lateral gas flow and leakages also contribute to non linearity. Several models have been suggested to account for this non linearity, the most recent being the Hutchinson±Mosier regression model (HMR). However, the practical application of these models is challenging because the researcher needs to decide for each flux whether a nonlinear fit is appropriate or exaggerates flux estimates due to measurement artifacts. In the latter case, a flux estimate from the... |
