Abstract In the context of global changes affecting biodiversity worldwide, to what extent flower visitors -and not just bees- are threatened by different environmental factors needs to be evaluated. This is critical if we are to mitigate the effects of …

Abstract Several studies have now shown at different spatial scale that certain species of the wild bee fauna are in decline in Europe. In response, some European countries and the European commission are implementing action plans to mitigate negative …

Lecture prepared with Helge Bruelheide (German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig, Leipzig, Germany). Abstract In Germany (Central Europe) biodiversity has changed profoundly with respect to composition and spatial …

Abstract Resurveys of historical vegetation plots are invaluable to document patterns of change in community composition and diversity. They are also useful to better understand impacts of multiple and interacting global-change drivers. The relevance of …

Abstract Baseline surveys are essential to assess long-term shifts in plant communities. In the early 2000s, we re-surveyed 293   sites of six   forest types in Wisconsin, USA. Data from these sites, first surveyed in the 1950s, allowed us to infer …

Abstract The Danish monitoring program NOVANA has recorded the community composition of higher plants and selected soil chemical variable in terrestrial habitats since 2004. The monitoring program was developed as a response to the EU habitat directive …

Abstract Standardised long-term biodiversity monitoring schemes, based on repeated visits to fixed sites, offer the possibility of comparing biodiversity in space and time, while avoiding most of the biases associated with opportunistic data, particularly …

Abstract Switzerland's biodiversity is systematically surveyed by an array of programs, each designed to cover distinct facets of biodiversity across spatial scales as well as policy evaluation needs. Although each initiative has discrete aims, …

Abstract Long-term monitoring is a crucial tool for anticipating population collapse, which is particularly important in the case of priority species (rare, endangered or threatened). The 'Adopt a plant' programme was launched in 2013 as a collaborative …

Abstract Volunteer-based plant monitoring in the UK has focused historically on distribution mapping, with less emphasis on the collection of data on plant communities and habitats. However, abundance monitoring for other groups of organisms is …

Abstract Physical activities, now considered part of our leisure time, as well as sports in which certain individuals demonstrate exceptional abilities, were once daily and vital practices for our most remote ancestors. Adaptations to climbing, bipedal …

On Thursday April 25 , Entre-Temps organized two round tables at the Collège de France as part of the commemoration of the 30th anniversary of the Tutsi genocide in Rwanda. An opportunity to reflect collectively on the experiences of this recent past. For …

Summary Tracing back to the four interlocked ibexes walking in a circle that features the so-called "Hunt Patera" (in the Louvre Museum) from the temple of Baal at Ugarit, Syria, dated to the 14th-13th  century BCE, this lecture discusses the original …

Abstract The importance of the body in Étienne-Jules Marey's research may seem obvious : the walking man, the trotting horse, the bird and the insect in flight are the privileged objects of the graphic method and chronophotography. Beyond this, the …
