A novel cuvette enclosure approach was applied on 18 individuals and emission rates were derived using proton transfer reaction-mass spectrometry (PTR-MS) and gas chromatography–mass spectrometry (GC–MS) techniques. Complementary chlorophyll fluorescence and CO2 uptake measurements were performed for all of the samples. Q. robur seedlings remained unaffected by flood. On the contrary, P. serotina seedlings reduced their chlorophyll fluorescence yield by 34.5 ± 4.1 % and their CO2 uptake by 67.5 ± 10.5 %. These observations along with the highest acetaldehyde emissions recorded indicate strong susceptibility to water stress. Drought had a similar impact on both species that reduced chlorophyll fluorescence yield, CO2 uptake, and the emission rates of most VOC. Nevertheless, isoprene was found to be emitted more than 20 times stronger by Q. robur seedlings under all treatments. In general, most VOC emissions increased with soil water availability displaying an exponential trend for acetaldehyde and methanol and a linear one for the sum of mono- and sesquiterpenes. Only methyl salicylate was released about two times stronger from oaks under drought conditions in comparison to wet conditions. Considering their VOC emission behavior, Q. robur seedlings appear to tolerate flood much better than P. serotina and thus it is likely to have a competing advantage under these conditions."],["dc.identifier.doi","10.1007/s00468-013-0942-5"],["dc.identifier.gro","3146731"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/4527"],["dc.language.iso","en"],["dc.notes.status","zu prüfen"],["dc.relation.issn","0931-1890"],["dc.title","Impact of flooding and drought conditions on the emission of volatile organic compounds of Quercus robur and Prunus serotina"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

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.

Golden Delicious) foliage that was either intact, mechanically-damaged, or exposed to larval feeding by Pandemis heparana (Denis and Schiffermuller) (Lepidoptera: Tortricidae). Volatiles were collected by closed-loop-stripping-analysis and characterized by gas chromatography-mass spectrometry in three time periods: after 1 h and again 24 and 48 h later. Volatiles for all treatments also were monitored continuously over a 72-h period by the use of proton transfer reaction - time of flight-mass spectrometry (PTR-ToF-MS). In addition, the volatile samples were analyzed by gas chromatography-electroantennographic detection (GC-EAD) using male and female antennae of P. heparana. Twelve compounds were detected from intact foliage compared with 23 from mechanically-damaged, and 30 from P. heparana-infested foliage. Interestingly, six compounds were released only by P. heparana-infested foliage. The emission dynamics of many compounds measured by PTR-ToF-MS showed striking differences according to the timing of herbivory and the circadian cycle. For example, the emission of green leaf volatiles began shortly after the start of herbivory, and increased over time independently from the light-dark cycle. Conversely, the emission of terpenes and aromatic compounds showed a several-hour delay in response to herbivory, and followed a diurnal rhythm. Methanol was the only identified volatile showing a nocturnal rhythm. Consistent GC-EAD responses were found for sixteen compounds, including five aromatic ones. A field trial in Sweden demonstrated that benzyl alcohol, 2-phenylethanol, phenylacetonitrile, and indole lures placed in traps were not attractive to Pandemis spp. adults, but 2-phenylethanol and phenylacetonitrile when used in combination with acetic acid were attractive to both sexes."],["dc.identifier.doi","10.1007/s10886-016-0794-8"],["dc.identifier.isi","000390040400007"],["dc.identifier.pmid","27896554"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/38828"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1573-1561"],["dc.relation.issn","0098-0331"],["dc.title","Emission of Volatile Compounds from Apple Plants Infested with Pandemis heparana Larvae, Antennal Response of Conspecific Adults, and Preliminary Field Trial"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Despite the importance of the home range concept, there is no consensus on how to estimate the HRS of animals. Assessments of the performance of commonly applied HRS estimators have largely been based on simulated data or on location data of few sample individuals occupying one study area. To empirically evaluate the impact of supplementary feeding, habitat composition, red deer sex, and estimation method (minimum convex polygon (MCP), kernel density estimator (KDE) and alpha-local convex hull (alpha-LoCoH)) on HRS, we analysed the data of 183 annual red deer home ranges using a mixed modelling approach. Red deer HRSs were smallest in areas with substantial supplementary feeding, intermediate in areas with closed forest cover but no supplementary feeding, and largest in fragmented landscapes where supplementary feeding rarely occurs. Consistently, male HRSs were larger than female HRSs. While MCP- and KDE-HRS estimates were roughly similar, estimates from the alpha-LoCoH method were substantially smaller than those of MCP and KDE. Analyses of 342 seasonal HRS largely reflected patterns of annual HRS. However, seasonal HRS differed between seasons and red deer sex. In areas with no or little feeding, red deer adjusted HRS seasonally, whereas red deer supplied with supplementary food during winter did not alter their HRS seasonally. Our study suggests that supplementary feeding and habitat configuration strongly affect the spatial ecology of red deer; this might have considerable sanitary and ecological implications. We suggest that sex differences in annual space use extent are proportional along a resource gradient but are mediated by seasons. Finally, method-related variation in space use studies of animals needs to be considered more cautiously."],["dc.identifier.doi","10.1007/s10344-013-0772-1"],["dc.identifier.isi","000332759700010"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/33911"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1439-0574"],["dc.relation.issn","1612-4642"],["dc.relation.orgunit","Abteilung Wildtierwissenschaften"],["dc.title","Home range size estimates of red deer in Germany: environmental, individual and methodological correlates"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
