Interspecific competition, life history traits, environmental heterogeneity and spatial structure as well as disturbance are known to impact the successful dispersal strategies in metacommunities. However, studies on the direction of impact of those factor ...
The role of humans in the global dispersal of free-living terrestrial microorganisms has received surprisingly little attention in the literature, compared with the frequent discussions of human dispersal for aquatic microbes. Here I argue that this area n ...
Aim We investigate the long-standing question of whether the small size of microbes allows most microbial species to colonize all suitable sites around the globe or whether their ranges are limited by opportunities for dispersal. In this study we use a mod ...
Full-field X-ray microscopy is a valuable tool for 3D observation of biological systems. In the soft X-ray domain organelles can be visualized in individual cells while hard X-ray microscopes excel in imaging of larger complex biological tissue. The field ...
Within the framework of the POLARCAT-France campaign, aerosol physical, chemical and optical properties over Greenland were measured onboard the French ATR-42 research aircraft. The origins of CO excess peaks detected in the aircraft measurements then have ...
A long-standing debate in microbial ecology is the extent to which free-living microorganisms exhibit cosmopolitan distributions. We use a comparison of testate amoebae communities in cold "polar" locations (Arctic, Antarctic, and Tibet) to investigate how ...
Mass flux and void fraction measurement in a multiphase dense spray is a challenging task. The Phase Doppler Particle Anemometer (PDPA) cannot provide accurate mass flux measurements in a highly turbulent multiphase spray due to the presence of non-spheric ...
Due to the spongistatins' fascinating and complex molecular architectures, and their important biological activities, these marine macrolides have been the subject of intensive efforts directed towards their total synthesis. As an attractive alternative to ...
Two bubble column sequencing batch reactors fed with an artificial wastewater were operated at 20, 30 and 35°C. In a first stage, stable granules were obtained at 20°C whereas fluffy structures were observed at 30°C. Molecular analysis revealed high abunda ...
Pollen dispersal is a fundamental aspect of plant reproductive biology that maintains connectivity between spatially separated populations. Pollen clumping, a characteristic feature of insect-pollinated plants, is generally assumed to be a detriment to win ...
