Planetary upper atmosphere energetics is mainly governed by absorption of solar extreme ultraviolet (EUV) radiation. Understanding the response of planetary upper atmosphere to the daily, long and short term variation in solar flux is very important to quantify energy budget of upper atmosphere. We report a comprehensive study of Mars dayglow observations made by the IUVS instrument aboard the MAVEN spacecraft, focusing on upper atmospheric response to solar EUV flux. Our analysis shows both short and long term effect of solar EUV flux on Martian thermospheric temperature. We find a significant drop (> 100 K) in thermospheric temperature between Ls = 218° and Ls = 140°, attributed primarily to the decrease in solar activity and increase in heliocentric distance. IUVS has observed response of Martian thermosphere to the 27-day solar flux variation due to solar rotation.We also report effect of two solar flare events (19 Oct. 2014 and 24 March 2015) on Martian dayglow observations. IUVS observed about ~25% increase in observed brightness of major ultraviolet dayglow emissions below 120 km, where most of the high energy photons (< 10 nm) deposit their energy. The results presented in this talk will help us better understand the role of EUV flux in total heat budget of Martian thermosphere. [less ▲]

The kingfisher is widespread in Wallonia but is missing locally in middle Belgium and in higher Ardenne. The field prospection for the atlas took place in a favorable climatic context; the current population, estimated at 450 650 pairs, reflects probably the saturation of the habitat. The highest densities are found along large rivers, with important fishing ressources and numerous nesting sites (Lesse, Ourthe, Semois, Viroin). The limiting fator seems to be the lack of nesting sites. [less ▲]

In south-west Belgium, the breeding of the kingfisher was monitored for more than 10 years. During this period, 158 banks were regularly surveyed. Alterations or potential threats were identified: natural erosion, cattle trampling, disturbance from kayak-riders or anglers and, last but not least, consolidation works. Only 56 banks (35.4 %) can de considered as "safe". However, since the recent (2001) legal restrictions about the navigation on small rivers, 12 more banks are now safe too. Cattle trampling appears as the main threat (55 sites). However, the enforcement of the law regulating the fences along the rivers could easily solve the problem. Nineteen banks were completely destroyed for different purposes: navigation, road retaining walls or simply anti-erosive measures. Most of these works were undertaken along the river Meuse, the best nidification habitat of the area. (11 photos) [less ▲]

In his martyrology (published in 1660), the conservative Dutch Mennonite Tieleman Jansz. van Braght propose an original interpretation of the Christian past. In order to put together a succession of witnesses, he examines one by one the ancient or medieval spiritual ancestors who, at the time, were claimed by both Catholics and Protestants. Those who seems to have been submitting to the divine principles - such as the practice of adult baptism - are considered as orthodox ; furthermore, if the orthodox suffered for their faith, they were given the title of martyr. Among the chosen ones, we thus have, besides the Anabaptists themselves: the early Christians, the Donatists, the Waldenses and the Hussites. These believers become the members of a dissenting and persecuted Church, which had held its own since the days of the Apostles. This notion conflict with the idea of Reformatio et, a fortiori, with that of Restitutio which is generally ascribed to the Anabaptists of the sixteenth century. [less ▲]
