The effect of different management strategies on the dynamics of saproxylic insect habitatsŠEBEK, Pavel January 2016 (has links)
The thesis concerns studies on habitats utilized by insects associated with deadwood. It presents a review of current issues in the conservation of saproxylic biodiversity. The effects of active intervention on temperate lowland woodland habitats, such as pollarding or coppicing, are evaluated in terms of their suitability for saproxylic communities and other groups. Further, the importance of open-grown trees for saproxylic diversity is assessed.

Biogéographie du microclimat foliaire : mécanismes et conséquences sur les relations plantes-insectes / Biogeography of the leaf microclimate : mechanisms and consequences on insect-plant interactionsCaillon, Robin 29 January 2016 (has links)
Les performances du végétal et des arthropodes dont il constitue le microhabitat dépendent des températures de surface foliaire. Celles-ci peuvent dévier fortement de la température de l’air et présenter des niveaux d’hétérogénéité différents selon l'échelle spatiale considérée. La feuille atténue les températures extrêmes en rapprochant son amplitude de variation journalière de celle de la température de l’air. Cependant, cette réponse diminue l’hétérogénéité des températures de surface foliaire et les capacités de thermorégulation comportementale des arthropodes à l'échelle de la feuille. Les températures moyennes de surface foliaire atténuent peu le réchauffement, et déterminent localement la performance photosynthétique du végétal. De l’échelle de la feuille à celle de la canopée, les plantes montrent des réponses différentes au réchauffement. Ce type de changement d'échelle est primordial pour améliorer notre compréhension de l'impact des changements climatiques. / Plant performance and leaf-dwelling arthropods are impacted by leaf surface temperatures. Leaf surface temperatures can show important deviation from air temperature and present different levels of heterogeneity depending on the spatial scale. The leaf buffers temperature extremes by getting closer in amplitude to air temperature. However, this physiological response decreases the heterogeneity of temperatures at the leaf surface and the opportunities for arthropods to behavioraly thermoregulate in this microclimate. Mean temperatures at the leaf surface show low buffering abilities in response to warming and locally determine photosynthetic performance. From the leaf to the canopy scale, plants show different responses to warming and scaling is crucial to increase our understanding of the impact of global warming.
