We analyze the ultraviolet dayglow in the atmosphere of Mars through CO2+ and CO Cameron emissions. These emissions are accumulated on a large dataset of dayside grazing limb performed by the Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars (SPICAM) instrument on board the Mars Express spacecraft. The temperature of the Martian upper atmosphere can be retrieved from these limb emission profiles. We present discussion on the validity domain for such retrieval. We also show evidence for local (spatial and temporal) variability in the scale height of the atmosphere at the altitude of these emissions. [less ▲]

A large dataset of dayside grazing limb CO2+ observations performed by the SPICAM (Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars) instrument on board Mars Express is analyzed to retrieve Martian thermospheric temperature, as well as its variation with solar activity, season and latitude. The method permits to retrieve the temperature from the scale height of the CO2+ emission. We also present puzzling features such as limb profiles exhibiting multiple peaks and their characteristics. We furthermore study the behavior of the main emission peak of the CO2+ vertical emission profiles. The CO2+ emission at 289 nm arises from the relaxation of the CO2+* molecule in the B2Σ+ state to the X2Π state. CO2+* molecules are mainly produced in the Martian dayside through photoionisation and photoelectron impact. The CO2+ emission exhibits features that constrain the temperature and density vertical profiles of CO2. Comparisons of retrieved temperatures are made with corresponding simulations from the coupled MGCM-MTGCM. We also use a Monte-Carlo code to model the observed intensity limb profiles. [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 ▲]
