The softwood communities found there are unique habitats for many butterflies. The studies conducted in the vicinity of Göttingen resulted in 83 Makrolepidoptera taxa found on willow (Salix caprea) and 65 on poplar (Populus tremula). Since different plants emit different volatiles, many insects are able to follow the odour plumes and find their hosts by perceiving various odours. The emission of volatiles can be influenced by different external factors, like surplus of salts, drought, mycorrhiza. A gas-chromatograph with mass-spectrometric and parallel electroantennographic detector (GC-MS/EAD) was employed to measure in what way the volatile pattern changed and which of the associated chemical substances could be detected by the insect antennae. The volatile pattern is very important for butterflies to find their habitat."],["dc.identifier.gro","3149773"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6471"],["dc.language.iso","de"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.publisher","Vorstand der DGaaE"],["dc.publisher.place","Halle"],["dc.relation.conference","Entomologentagung"],["dc.relation.crisseries","Mitteilungen der Deutschen Gesellschaft für allgemeine und angewandte Entomologie"],["dc.relation.eventend","2005-03-24"],["dc.relation.eventlocation","Dresden, Germany"],["dc.relation.eventstart","2005-03-21"],["dc.relation.ispartof","Vorträge der Entomologentagung in Dresden vom 21. bis 24.

Since forests constitute the most important European ecosystems, in this review article we assess current knowledge on the effects of heat and drought on key metabolic processes for growth and productivity of forest trees. In particular, the general consequences of heat and drought on (1) photosynthesis and respiration at the cellular and community level, and (2) on nutrient uptake, partitioning and competition for nutrients are summarized. The latter are a major sink for photosynthetic energy and, therefore, are indirectly but strongly connected to the performance of photosynthesis. In addition, the interaction of heat and drought with stress compensation mechanisms and emission of biogenic volatile organic compounds (BVOC) are discussed, since these processes are directly connected to carbon metabolism. Effects on the emission of BVOC are also included because they constitute an important feedback mechanism on ozone formation and, thus, on atmospheric pollution. As far as available, data collected during the 2003 heat wave are included and discussed."],["dc.identifier.doi","10.1055/s-2006-924084"],["dc.identifier.gro","3147346"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/4952"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1435-8603"],["dc.title","Physiological Responses of Forest Trees to Heat and Drought"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Roots of well-irrigated plants were about 75% colonized with P. involutus regardless the presence of hydrogel. Drought stress resulted in an about 10% loss of EM. Non-inoculated plants showed marginal EM colonization (3%). EM poplar in hydrogel-amended soil maintained the highest pre-dawn water potential under drought stress, showed lowest biomass loss and kept almost full photosynthetic activity, whereas non-EM plants in soil without hydrogel exhibited severe leaf loss under these conditions and did not show net CO2 assimilation. Non-EM plants in hydrogel-amended soil and EM plants without hydrogel showed intermediate stress symptoms. The soluble carbohydrate content of roots was correlated with the pre-dawn potential indicating osmotic regulation under drought stress. EM plants displayed larger vessel cross-sectional areas and increased radial stem growth compared with non-EM plants. EM plants contained the lowest numbers of vessels (mm−2) but the largest vessel diameters, whereas non-EM drought-stressed plants in soil without hydrogel showed the smallest vessel diameters and highest vessel numbers. Vessel diameter and vessel numbers were strictly inversely correlated suggesting strong developmental coordination between these two parameters. The finding that neither vessel diameters nor vessel numbers were correlated with the pre-dawn water potential suggests that the coordination between these wood features may be achieved by signals acting independent of acute water stress. Overall, EM and hydrogel, especially in combination, help to avoid drought stress. Thereby, these soil amendments improve plant performance and may be useful for the establishment of plantations on marginal sites."],["dc.identifier.doi","10.1016/j.envexpbot.2010.02.005"],["dc.identifier.gro","3147208"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/4840"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0098-8472"],["dc.title","Ectomycorrhiza and hydrogel protect hybrid poplar from water deficit and unravel plastic responses of xylem anatomy"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Objectives The goal of this study was to characterize the response of beech seedlings to planting stress and to test if soil amendment with a mixture of hydrogel and the ectomycorrhizal fungus Paxillus involutus could rescue the establishment of stressed plants. For this purpose, bare-rooted, dormant seedlings were exposed for 0, 2 and 6 h to air before planting. Results Water loss in response to air exposure caused increasing concentrations of soluble carbohydrates in buds and fine roots suggesting only passive of osmoprotection. Short-term exposure for 2 h delayed bud burst in spring, whereas long-term stress for 6 h also increased mortality. Growth of the seedlings in amended soil improved plant performance compared with plant grown in untreated soil. In particular, mycorrhizal colonization, plant water status and biomass increased, whereas carbohydrate storage pools were decreased. Total plant nitrogen allocated to leaves but not the nitrogen or carbohydrate concentrations were correlated with the degree of ectomycorrhizal colonization. Conclusion This suggests that soil amendment enhanced nitrogen uptake via ectomycorrhizals, which in turn stimulated growth, thereby, increasing carbon consumption and preventing starch accumulation. In conclusion, soil amendment with hydrogel and an ectomycorrhizal fungus significantly improved the performance of both stressed and unstressed young beech trees."],["dc.identifier.doi","10.1007/s13595-011-0077-z"],["dc.identifier.gro","3147207"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7402"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/4839"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1286-4560"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Amelioration of planting stress by soil amendment with a hydrogel–mycorrhiza mixture for early establishment of beech (Fagus sylvatica L.) seedlings"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
