title: 2D automated electrical resistivity tomography (A-ERT) at Deception Island, Antarctica

description: Climate induced warming of permafrost soils is a global phenomenon, with regional and site-specific variations, which are not fully understood. In this context, a 2D automated electrical resistivity tomography (A-ERT) system was installed for the first time in Antarctica at Deception Island, associated to the existing Crater Lake site of the Circumpolar Active Layer Monitoring Network (CALM-S). This set-up aims to I) monitor subsurface freezing and thawing processes on a daily and seasonal basis and to map the spatial and temporal variability of thaw depth, and to II) study the impact of short-lived extreme meteorological events on active layer dynamics. In addition, the feasibility of installing and running autonomous ERT monitoring stations in remote and extreme environments such as Antarctica was evaluated for the first time. Measurements were repeated at 4-hour intervals during a full year, enabling the detection of seasonal trends, as well as short-lived resistivity changes reflecting individual meteorological events. The latter is important to distinguish between (1) long-term climatic trends and (2) the impact of anomalous seasons on the ground thermal regime. The A-ERT.txt file contains all ERT surveys which were performed using Wenner electrode configuration. 20 copper plates, which are connected by buried cables to the active boxes, with an electrode spacing of 0.5 m were used in this experiment. This setup yields 56 individual data points for each monitoring data set at six data levels. All data were saved in the Res2Dinv format. The temperature. xlsx file contains air and ground temperatures data during the experiment period. The Air temperature was measured at 160 cm above the surface and ground temperatures in the shallow borehole S3,3 were measured with ibutton-sensors at depths 2.5, 5, 10, 20, 40, 80 and 160 cm.

title: Onion endophyte colonization of Thrips

description: Endophytic fungi, which live within host plant tissues without causing any visible symptom of infection, are important mutualists that mediate plant-herbivore interactions. Thrips tabaci (Lindeman) is one of the key pests of onion, Allium cepa L., an economically important agricultural crop cultivated worldwide. However, information on endophyte colonization of onions and their impacts on the biology of thrips feeding on them are lacking. We tested the colonization of onion plants by selected fungal endophyte isolates with two inoculation methods. The effects of inoculated endophytes on T. tabaci infesting onion were also examined. Seven fungal endophytes used in our study were able to colonize onion plants either by seed or seedling inoculation methods. Seed inoculation yielded 1.47 times higher mean percentage post-inoculation recovery of all the endophytes tested at (48.48 ± 8.1) as compared to seedling inoculation (32.87 ± 5.5). The lowest thrips numbers were recorded in Hypocrea lixii F3ST1 (1.6 ± 0.6) colonized plants as compared to the control (9.5 ± 1.5). Onion plants colonized by Clonostachys rosea ICIPE 707, Trichoderma asperellum M2RT4, Trichoderma atroviride ICIPE 710, and H. lixii F3ST1 had significantly lower feeding punctures as compared to the other treatments. Lowest number of eggs were laid by T. tabaci on H. lixii F3ST1 (1.5 ± 0.6) treatments followed by C. rosea ICIPE 707 and T. harzianum ICIPE 709 as compared to the control (18.6 ± 2.2). The number of feeding punctures and eggs were positively correlated (r = 0.805, d.f. = 30, P &lt; 0.001). These results extend the knowledge on colonization of onions by fungal endophytes and their effects on Thrips tabaci.
description: The data sets presents observations on the percent colonization of onion roots, stem and leaves by seven endophytic isolates viz., Clonostachys rosea ICIPE 707, Trichoderma atroviride ICIPE 710, Trichoderma harzianum ICIPE 709, Fusarium sp. ICIPE 712, Fusarium sp. ICIPE 717, Hypocrea lixii F3ST1 and Trichoderma asperellum M2RT4 inoculated by seed and seedling treatment techniques. The endophytes were isolated from onion, maize and sorghum plants asymptomatic of any pathogenic infection, collected during a field survey from different altitudes of Kenya. Further observations on the number of feeding punctures, egg laying and survival after 72h of Thrips tabaci on endophyte colonized onion plants are presented. Correlation data between number of feeding punctures and number of egg laid are also presented.

title: delta 13C, delta 15N and delta 34S of temperate eelgrass food web in the western Baltic Sea

description: Simultaneous triple stable isotope analysis of carbon, nitrogen and sulphur was employed to study the temporal variation in the food web of a subtidal eelgrass (Zostera marina) bed in the western Baltic Sea. Samples of three potential food sources: eelgrass, epiphytes and seston, as well as consumer species were collected biweekly from March through September 2011. Temporal variation of stable isotope signatures was observed in primary producers and consumer species. However, variation within a species, particularly omnivores, often exceeded variation over time. The high degree of omnivory among the generalist feeders in this eelgrass community allows for generalist feeders to flexibly switch food sources, thus enhancing food web stability. As coastal systems are subject to seasonal changes, as well as alterations related to human disturbance and climate, these food webs may retain a certain resilience due to their plentiful omnivores.

title: Occurence of flood laminae in sediments of Ammersee

description: A 450 year spring-summer flood layer time series at seasonal resolution has been established from the varved sediment record of Lake Ammersee (southern Germany), applying a novel methodological approach. The main results are (1) the attainment of a precise chronology by microscopic varve counting, (2) the identification of detrital layers representing flood-triggered fluxes of catchment material into the lake, and (3) the recognition of the seasonality of these flood layers from their microstratigraphic position within a varve. Tracing flood layers in a proximal and a distal core and correlating them by application of the precise chronology provided information on the depositional processes. Comparing the seasonal flood layer record with daily runoff data of the inflowing River Ammer for the period from 1926 to 1999 allowed the definition of an approximate threshold in flood magnitude above which the formation of flood layers becomes very likely. Moreover, it was possible for the first time to estimate the "completeness" of the flood layer time series and to recognize that mainly floods in spring and summer, representing the main flood seasons in this region, are well preserved in the sediment archive. Their frequency distribution over the entire 450 year time series is not stationary but reveals maxima for colder periods of the Little Ice Age when solar activity was reduced. The observed spring-summer flood layer frequency further shows trends similar to those of the occurrence of flood-prone weather regimes since A.D. 1881, probably suggesting a causal link between solar variability and changes in midlatitude atmospheric circulation patterns.

Total procedural blanks averaged apporx. 1 ng for Sr and 100 pg for Nd, during the study period. Measured 87Sr/86Sr ratios were analyzed using four-collector static mode measurements. Thirty measurements of SRM-987 during the study period yielded mean 87Sr/86Sr=0.71032±2. Measured 143Nd/144Nd normalized to 146Nd/144Nd=0.7219. Analyses were dynamic mode, three-collector measurements. Thirty three measurements of the La Jolla Nd standard during the study period yielded a mean 143Nd/144Nd=0.511838±8 (2sigma mean). e-Nd values are calculated using a present-day 143Nd/144Nd (CHUR)=0.512638.

title: (Table 1) Total carbonate content of ODP Leg 134 samples

description: Depositional processes in the collision zone between the North d'Entrecasteaux Ridge (NDR) and the New Hebrides Island Arc were investigated in post-cruise analyses of sediment and nannofossils from Sites 827, 828, and 829. Reexamination of cores and analysis of grain size, turbidite frequency, carbonate content, and clay mineralogy, together with new nannofossil age determinations, were used to revise shipboard lithostratigraphies and interpret the sedimentologic history recorded at each site.The results of our analyses show that sedimentation on the inner trench slope and the impinging NDR has been significantly affected by the collision process. Uplift associated with subduction of the NDR beneath the New Hebrides Island Arc resulted in the emergence of Espiritu Santo Island and created a robust source of epiclastic sediment for the forearc area. Distribution of this material into deeper water has been modulated by Pleistocene sea level changes, which have influenced the frequency and extent of turbidity currents. Sedimentation at individual sites reflects the interplay between sediment source availability, sea level changes, and tectonic displacements, which have translated local depositional environments both horizontally and vertically. The study also provides evidence that ridge sediment and trench fill deposits have been accreted onto the forearc slope and that thrust faulting of subducting ridge sediment has occurred preferentially in kaolinite-rich horizons.
