Long considered simply as anoxic fermentors, termite guts are in fact axially and radially structured environments with physicochemically distinct microhabitats. Recent developments in termite gut microecology, which combined traditional and modern techniques, have focused on the spatial organization of important microbial populations and their in situ activities, and have significantly further...

The bacterium Serratia plymuthica strain S13 was demonstrated to colonize various plant-associated microhabitats and to suppress damping-off diseases. The completed genome sequence has a size of 5.5 Mb, containing 4,957 putative protein-encoding regions, and will be used to identify genetic determinants enabling the bacterium to escort a plant's entire life cycle.

Actuellement en Europe, les populations d’Unio crassus (Bivalvia : Unionidae) déclinent rapidement. Afin de contrer cette tendance, nombreuses actions conservation sont mises place. Toutefois, l’efficacité ces est dépendante notre connaissance l’écologie l’espèce. Cette étude se concentre sur préférences hydromorphologiques d’U. dans une rivière du sud-est la Belgique (la Sûre). La profondeur e...

Escape by Anolis lizards is influenced by microhabitats and fight initiation distance increases with predation risk. Differences in microhabitat use among ecomorphs affect escape behavior, but only two studies have reported ecomorphological differences in flight initiation distance among Greater Antillean species. I studied effects of predation risk and microhabitats on escape behavior by condu...

The objective of this study is to understand the response of Quercus suber seedlings to light and water, two limiting factors of their growth and survival in Mediterranean woody plants. Greenhouse and field experiments were conducted to contrast the results from both types of experiments. At the greenhouse experiment, Quercus suber seedlings were grown at three treatments of light (3%, 27% and ...
