Given a worldwide preference for suffixes over prefixes, why do some languages nonetheless have a macro-preference for prefixes? In this talk, we show that Ancient Egyptian-Coptic (Afroasiatic) shows a long-term diachronic macro-change from mixed suffixing-prefixing to an overwhel¬ming preference for prefixing. We argue that each of the micro-changes implicated in this macro-change are better understood in terms of regular changes at the level of individual constructions, via, e.g., grammaticalization, rather than in terms of a broad Sapirian ‘drift.’ Crucially, it is the particular constellation of structural features of the language at a particular moment in time, together with regular mechanisms of language change, that give rise to the cross-linguistically unusual ‘macro-preference’ of the language.

Drier condition during the growing season have been predicted in the future. It has been suggested that diverse forest could maintain productivity and provide better ecosystem services under stress condition such as drought. However, those studies focused mainly on mature forest and little known about young forest. Oak and beech are the important species in European forestry, and may face a strong challenge in the future. Drought effects on young ( ̴5yr) oak and beech saplings in monoculture and mixed with other species are not known. Moreover, single studies evaluating both above- and below-ground ecosystem response to drought are scarce. A two-year manipulative field experiment has been planned to answer the following questions. (i) Can species mixtures improve oak and beech sapling performances under drought conditions? (ii) What are the mechanisms underlying ecosystem functioning and sapling performance in mixed species stands subjected to drought? A 3m × 3m rainout shelter will be placed only in growing season in Zedelgem sites of FORBIO experimental platform (http://www.treedivbelgium.ugent.be/pl_forbio.html). Tree diversity vary from 1 to 4 species and about 50% of precipitation will be taken off. Both aboveground sapling performance and belowground microbial properties and biogeochemical processes will be investigated. We will present the design of the experimental tree species diversity plantation of Zedelgem site, the setting of the drought experiment and planned analysis [less ▲]

L’utilisation de l’allométrie hauteur-diamètre globale ou régionale en milieu tropical pourrait avoir des conséquences importantes dans les estimations de biomasse et des stocks de carbone. L’objectif de ce travail est d’identifier les variations de l’allométrie hauteur-diamètre au sein de deux types de forêts (forêt sempervirente et forêt semi-décidue) au sud du Cameroun et d’examiner leurs conséquences sur les estimations de biomasse. Le diamètre et la hauteur ont été mesurés sur un total de 521 arbres appartenant à 15 espèces et couvrant une gamme de diamètre de 10 à 240 cm. Une calibration des mesures non destructives et destructives de la hauteur a été réalisée sur 60 arbres. Dix modèles allométriques ont été ajustés sur ces données. Le meilleur modèle a été sélectionné avec Akaike Information Criterion (AIC). L’allométrie hauteur-diamètre au niveau des sites et entre les espèces a montré une tendance asymptotique (Modèle de Michaelis-Menten). Pour un même diamètre, les arbres étaient plus hauts dans les forêts semi-décidues que dans les forêts sempervirentes. Les différences de biomasse entre les deux types de forêts sont dues par les variations de l’allométrie hauteur-diamètre. Les variations de l’allométrie hauteur-diamètre sont donc d’une extrême importance dans les estimations de biomasse et des stocks de carbone des forêts denses humides tropicales d’Afrique centrale.

In glioblastoma patients with similar prognostic factors—like age, performance status and extent of surgical resection—clinical evolution is still variable. In addition, the benefit of resection of recurrent tumours is uncertain. In this study, prognostic subgroups are established on a clinical basis and the benefit of surgery for recurrence is compared between them. Recursive partitioning analysis on EORTC sample 26981 (n=239) identified clinical factors influencing Progression-Free Survival (PFS), in order to create prognostic subgroups, whose PFS and survival after recurrence were compared using Kaplan-Meier curves and log-rank tests. Results were validated on a sample from Liège University Hospital (n=92). WHO Performance Status (WHO-PS) and age at first intervention (“age”) defined 4 subgroups. PFS was shorter in WHO-PS 2–3 than WHO PS 0–1 patients. In both groups, age was the second classifying factor (cut-off: 47.5y for WHO-PS 0–1, 60.5y for WHO-PS 2–3). The 4 subgroups had significantly different median PFS (77.5, 144, 234.5 and 346.5 days) and median overall survival (126, 330, 476 and 675 days). Survival after recurrence was correlated with PFS, and recurrence resection was associated with longer survival, regardless of the prognostic subgroup. Clinical prognostic glioblastoma subgroups with distinct PFS exist and can be defined by WHO-PS and age. This classification can be used as a clinical basis to identify molecular patterns associated with prognosis. In addition, in all subgroups, this retrospective analysis suggests a benefit of surgical resection when feasible. [less ▲]

Die deutschsprachigen Belgier betrachten ihre jüngere Geschichte zumeist aus der Perspektive einer Minderheit. Die Erinnerung an den Ersten Weltkrieg vor hundert Jahren bietet Christoph Brüll den Anlass, sich mit der damals wohl kleinsten Minderheit des deutschen Kaiserreiches zu befassen: den rund 10.000 „preußischen Wallonen“ im Kreis Malmedy. Der Vortrag fragt nach deren Identität im Kaiserreich, wo sie zu Kollateralopfern der gegen größere Minderheiten gerichteten Germanisierungspolitik wurden, woraus ein wallonischer Kulturpartikularismus an der deutsch-belgischen Grenze resultierte. Dabei wird auch die Offenheit dieser Grenze vor dem August 1914 deutlich, die durch intensive grenzüberschreitende soziale, wirtschaftliche und auch kulturelle Kontakte gekennzeichnet ist. Umso dramatischer wurde dort der Beginn des Ersten Weltkriegs empfunden. Die Haltung der Bevölkerung während dieses Kriegs ist jedoch von der Forschung bisher kaum in den Blick genommen worden. Der Prozess einer sich beschleunigenden Nationalisierung der kleinen Region und die Reaktion der Bevölkerung darauf werden anhand verschiedener Aspekte wie Militär, Kirche und Schule dargestellt. Der Vortrag geht auch auf die Erfahrung des Kriegsendes und der darauf folgenden Besatzungszeit durch britische Truppen, die im August 1919 von belgischen Soldaten abgelöst wurden, ein. Nicht zuletzt unternimmt er den Versuch, die Entwicklung der Jahre 1914-1920 nicht von ihrem Ende – d.h. aus der Sicht des Staatenwechsels von 1920 – zu betrachten, womit die Kriegs- und Nachkriegserfahrung der Bevölkerung in den Mittelpunkt der Betrachtung rückt .

Conservation of large wildlife species is currently a major issue in Africa. Protected areas dedicated for biodiversity conservation unfortunately do not suffice and conservation practices must be extended to man-used areas. But in those areas conservation actions are limited because of conflicts between human and wildlife especially due to damages on crops. The worst crop raiders known are elephants because they can destroy the yearly harvest of a field in a single visit. This threatens not only people livelihoods but also elephants themselves when angry farmers retaliate by shooting or trapping them. After decades of investigations crop raiding drivers related to elephants’ ecophysiology remain largely unknown. A pilot study was conducted between July and November 2014 in Monts de Cristal National Park (Gabon, central Africa) to have a first view on environmental drivers to crop raiding. While the presence of some fruiting trees around crop fields lead to more damages, high slopes discouraged elephants. In further experiments, the link between the nutritive value of raided plants and the animal’s physiological requirements and status will be assessed through hormones and parasites measurements; while tracking of individual elephants’ movements using DNA analyses in feces will be done.

In this study we investigated the climatic niche between and within closely related tropical tree species of the Erythrophleum genus (Fabaceae, Caesalpinioideae): E. ivorense, E. suaveolens and E. africanum. Two major hypotheses, the refuge theory and the ecological gradient hypothesis, have been developed to explain the current distribution of tree clades across tropical Africa. To identify the speciation mechanisms, we used a combination of geographic data and environmental factors to quantify the degree of niche conservatism (or divergence). We used two sets of distribution data for the purpose of this study. Species distribution data for the whole of tropical Africa was gathered from herbarium records. Distribution data of the two sister species E. ivorense and E. suaveolens assigned to genetic cluster were available for the lowland tropical forests of western and central Africa. Using a Species Distribution Model approach based on MaxEnt algorithm we tested for the environmental differences between species and genetic clusters within species. At species level, the climatic niche significantly differed and only slightly overlapped, suggesting a parapatric speciation along a climatic gradient. Within the two sister species, the niche of the parapatric central African genetic clusters suggests mostly a secondary contact following the recolonization from different forest refugia. [less ▲]

In the Western Highlands agro-ecological zone of Cameroon, rivers are constantly silted and polluted with eroded sediment and waste from cultivated land. This study characterizes and quantifies the amount of material coming from plots cultivated in the Méloh Watershed. In a natural rocky-bottomed well measuring 0.90 m deep, 3 m long, and 2.5 m wide, for a period of three years we performed the collection, differentiation, and measurement of trapped sediment in the cultivated part of river that runs through the watershed. Both cultivated sides of the watershed had fairly regular slopes of 14% on one side and 17% on the other side. The material retrieved consisted of soil, plant residues, chemical packages, and plastic casing used for irrigation. During the years 2012 and 2013, farmers practiced both flatbed cultivation and ridging along the steepest slopes. These two methods of land preparation are inefficient in terms of water conservation, as evidenced by the collection of 10.429 t.ha-1 average total sediment per year during this period. Tied ridging cultivation method was experimented during the 2013 crop year and adopted on 75% of plots in 2014. We subsequently collected 3.586 t.ha-1 total sediment, a decrease of 65.61% compared to the average of previous years. The tied ridging cultivation method significantly reduced siltation of the Méloh River (p<0.05). This study showed that traditional agricultural practices are a principal cause of siltation and pollution of the Méloh River. By extrapolation, we can state that the problem must occur in almost all rivers in the study area with similar topography and agricultural practices [less ▲]
