La fertilisation forestière

Changements de la couverture forestière dans l'île d'Anjouan entre 1995 et 2014

Agriculture production linked to population growth is one of the main motors of forest degradation in the World. In the Union of the Comoros, deforestation is particularly attributed to slash-and-burn farming as well as cultures in the forest and other uses of the forest such as charcoal production. In recent times, very few statistic and cartographic information is known concerning the spatiot...

Processus de conduite de la recherche et ingénierie des processus : vers une fertilisation croisée

Leading research in human centred computer science needs guidance for helping researchers in elaborating and evaluating their contribution. With this goal, we propose THEDRE, a process to lead research in human centred computer science. In order to evaluate THEDRE, we use Promote, a taxonomy for Software Development Process Model. This work allows us to identify limits of THEDRE, but also of Pr...

A model-based constraint on CO2 fertilisation

We derive a constraint on the strength of CO2 fertilisation of the terrestrial biosphere through a “top-down” approach, calibrating Earth system model parameters constrained by the post-industrial increase of atmospheric CO2 concentration. We derive a probabilistic prediction for the globally averaged strength of CO2 fertilisation in nature, for the period 1850 to 2000 AD, implicitly net of oth...

Molecular aspects of avian oogenesis and fertilisation.

In this paper, we summarise studies which have been carried out on the metabolism of nucleic acids (maternal RNA, DNA, nucleolytic enzymes) in avian oocytes and embryos (Japanese quail, Coturnix coturnix japonica ) within the last 10 years in the Institute of Genetics and Animal Breeding of the Polish Academy of Sciences. The accumulation of maternal RNA in the quail oocyte during oogenesis is ...
