Understanding the nature of the earliest complex fossils has presented many challenges over the past century since Billings first described Ediacaran fossils from Newfoundland in 1872. Previous studies have documented abundant Ediacaran fossils in the Bonavista Peninsula of Newfoundland. This thesis focuses on the H14 surface north of Catalina, which contains a nearly monospecific assemblage that includes hundreds of specimens of the rangeomorph, Fractofusus andersoni. Three factors need to be considered when trying to interpret these organisms. The first of these three factors is structural deformation. The area has undergone deformation during the formation of the Appalachian orogenic belt. This has distorted both fossil shape and orientation, requiring retrodeformation to restore the shapes and relationships of fossils to their original form. Two additional taphonomic factors influencing fossil visibility are: partly or completely ash covered fossils and the removal of fossil impressions from the bedding plane by modern weathering. These processes hinder acceptance of some previously published interpretations.

L'hébergement d'un enfant polyhandicapé, c'est-à-dire un enfant présentant une association de déficience motrice et intellectuelle sévère et profonde, est existant au Québec et peu connu de la population. Jusqu’à maintenant, les savoirs sur l’hébergement pédiatrique et l’expérience des parents sont peu nombreux et ne permettent pas de guider le développement d’interventions infirmières adaptées aux besoins des parents. Pour pallier cette situation, une étude d’inspiration phénoménologique a été effectuée afin d’explorer la signification de l’expérience d’être parent d’un enfant polyhandicapé hébergé en établissement de longue durée pédiatrique. Sept entretiens semi-structurés individuels ont été réalisés avec le parent d’un enfant polyhandicapé hébergé dans un établissement pédiatrique de la grande région montréalaise. Afin d’adopter une vision systémique et contextuelle au domaine des sciences infirmières, l’approche systémique familiale selon le modèle de Calgary (Wright & Leahey, 2013) a été utilisée comme cadre de référence. Cette étude d’inspiration phénoménologique a permis de faire émerger trois thèmes quant au phénomène à l’étude, soit : a) héberger son enfant : une décision difficile à accepter, b) la signification de l’hébergement : une expérience tant positive que négative et c) la réappropriation du rôle de parent. Cette étude novatrice permet de fournir des résultats inédits sur l’expérience d’être parent d’un enfant gravement handicapé hébergé. Ils permettent aussi de mettre en évidence les sentiments des parents, leurs impressions et l’adaptation de leur rôle parental lorsque leur enfant est hébergé. Ces résultats pourront influencer ou guider les infirmières dans l’application quotidienne d’interventions familiales adaptées et personnalisées au besoin des parents vivant une situation semblable.

On 19 May 2015, the European Commission published a very comprehensive, ambitious and innovative Better Regulation package, which contains new guidelines on various phases of the policy cycle and various documents setting out the rules and functioning of entirely new consultation platforms and a new body in charge of regulatory scrutiny. This Special Report presents some initial impressions on the content of this remarkable set of new documents, which will shape the way in which EU policies will be prepared, shaped, monitored and evaluated in the years to come.

Intracellular endosymbiotic bacteria are common and can play a crucial role for insect pathology. Therefore, such bacteria could be a potential key to our understanding of major losses of Western honey bees (Apis mellifera) colonies. However, the transmission and potential effects of endosymbiotic bacteria in A. mellifera and other Apis spp. are poorly understood. Here, we explore the prevalence and transmission of the genera Arsenophonus, Wolbachia, Spiroplasma and Rickettsia in Apis spp. Colonies of A. mellifera (N = 33, with 20 eggs from worker brood cells and 100 adult workers each) as well as mated honey bee queens of A. cerana, A. dorsata and A. florea (N = 12 each) were screened using PCR. While Wolbachia, Spiroplasma and Rickettsia were not detected, Arsenophonus spp. were found in 24.2% of A. mellifera colonies and respective queens as well as in queens of A. dorsata (8.3%) and A. florea (8.3%), but not in A. cerana. The absence of Arsenophonus spp. from reproductive organs of A. mellifera queens and surface-sterilized eggs does not support transovarial vertical transmission. Instead, horizontal transmission is most likely.

An experiment was conceived in which we monitored degradation of GlcDGD. Independent of the fate of the [14C]glucosyl headgroup after hydrolysis from the glycerol backbone, the 14C enters the aqueous or gas phase whereas the intact lipid is insoluble and remains in the sediment phase. Total degradation of GlcDGD then is obtained by combining the increase of radioactivity in the aqueous and gaseous phases. We chose two different sediment to perform this experiment. One is from microbially actie surface sediment sampled in February 2010 from the upper tidal flat of the German Wadden Sea near Wremen (53° 38' 0N, 8° 29' 30E). The other one is deep subsurface sediments recovered from northern Cascadia Margin during Integrated Ocean Drilling Program Expedition 311 [site U1326, 138.2 meters below seafloor (mbsf), in situ temperature 20 °C, water depth 1,828 m. We performed both alive and killed control experiments for comparison. Surface and subsurface sediment slurry were incubated in the dark at in situ temperature, 4 °C and 20 °C for 300 d, respectively. The sterilized slurry was stored at 20 °C. All incubations were carried out under N2 headspace to ensure anaerobic conditions. The sampling frequency was high during the first half-month, i.e., after 1, 2, 7, and 14 d; thereafter, the sediment slurry was sampled every 2 months. At each time point, samples were taken in triplicate for radioactivity measurements. After 300 d of incubation, no significant changes of radioactivity in the aqueous phase were detected. This may be the result of either the rapid turnover of released [14C] glucose or the relatively high limit of detection caused by the slight solubility (equivalent to 2% of initial radioactivity) of GlcDGD in water. Therefore, total degradation of GlcDGD in the dataset was calculated by combining radioactivity of DIC, CH4, and CO2, leading to a minimum estimate.
