Carbon Discrimination against 13C during photosynthesis is a well characterized phenomenon. Plant matter produced during photosynthesis is depleted in 13C (lower 13C/12C ratio), compared to atmospheric CO2. The magnitude of this depletion mainly depends on the photosynthetic pathway of CO2 fixation. Plants endowed with C3 pathway have a lower 13C/12C ratio than plants exhibiting C4 [...]

Draft. In: Biogeochemistry and sustainable management. WeberV 2007 1. Abstract Human activities have often led to degradation of the world’s land resources. The global assessment of human-induced soil degradation (GLASOD) has shown that degradation results mainly from erosion and salinization, which are discussed in this review. Land conservation and rehabilitation of deserted or saline land are [...]

The Paper of Honney et al. was presented from WeberV at the “Current Topics in Grassland Science”, (29.10.07) Honney et al. (2007) found out, that the Globularia bisnagarica populations in Belgium (27) are characterized by high genetic differentiation (Gf=0,53, p<0,001). A Manteltest revealed a significant isolation by distance. Gene diversity within the populations was low (Hj=0,081) and [...]
