A field experiment designed to assess the biodiversity related to nettle strips closed to crops, and more particularly the aphid and related beneficial populations, was established in experimental farm located in Gembloux (Belgium). Margin strips of nettle (Urtica dioica) closed to wheat (Triticum aestivum), green pea (Pisum sativum) and rape (Brassicae napus) fields were investigated. The diversity, abundance of aphids and related predators were analysed according to the plant crop species and the differential pesticide application (treated plot and control). Insects were visually observed every week during all the cultivation season. Two main families of aphidophagous predators were found in all field crops and nettle, the Coccinellidae and Syrphidae. The diversity of the aphidophagous predators was shown to be higher on nettle than in field crops, particularly the Chrysopidae, the Anthocoridae and the Miridae. However, a striking difference of ladybird abundance was observed according to the aphid host plant. In one side, Coccinella septempunctata was much more abundant on Acyrthosiphon pisum infested green pea than on the other host plant species. At the opposite, higher occurrence of Harmonia axyridis was observed on the aphid infested nettle plants than on the crop plants. In particular, none of H. axyridis was found in wheat crop. Also, more than only a significant positive correlation between predator and aphid abundance, specialised relations between particular aphid species and some so-called generalist predators was determined in the fields. Finally, intraguild interactions between the aphidophagous predators was assessed and shown that only a significant negative correlation between Episyrphus balteatus and H. axyridis related to the nettle aphid, Micrlophium carnosum, was observed. The relative distribution of the ladybirds, namely C. septempunctata and H. axyridis according to the host plant, nettle strips and crop plots was discussed in relation to integrated pest management approach.

Inter- and Intraspecific Genetic Biodiversity in South East Asian Rodents: New Insights for Their Conservation

South East Asia displays a high level of mammal endemism and the highest number of threatened and data deficient mammal species. However, the South East Asian biodiversity is still highly unexplored. Because of the runaway global changes, a better biological knowledge of this region is urgently required to improve the conservation and the management of its biodiversity. The first aim of this chapter is to present recent published data on a biodiversity inventory of the Rattini murine rodents from this region based on molecular markers (Page`s et al., 2009). In this first study, we applied the method proposed by Pons et al. (2006) that determines with no a priori the locations of ancestral nodes that define putative species in order to investigate the current taxonomy of the Rattini tribe. Our second aim concerns the intraspecific genetic structure of a rare and threatened South East Asian mammal species: the murine rodent Leopoldamys neilli, endemic to karst habitats . In this latter study, our results evidenced a high geographic structure of the genetic diversity of this species. The observed highly divergent genetic lineages would have to be considered as distinct evolutionary units or at least as Management units. These results are essential for the best conservation issues of species endemic to karsts and to South East Asia, in general. In this chapter, we therefore highlight that South East Asia would not be only a hotspot of interspecific but also of intraspecific biodiversity. [less ▲]

Inter-annual variability of the carbon dioxide oceanic sink south of Tasmania

We compiled a large data-set from 22 cruises spanning from 1991 to 2003, of the partial pressure of CO2 (pCO(2)) in surface waters over the continental shelf (CS) and adjacent open ocean (43 degrees to 46 degrees S; 145 degrees to 150 degrees E), south of Tasmania. Climatological seasonal cycles of pCO(2) in the CS, the subtropical zone (STZ) and the subAntarctic zone (SAZ) are described and used to determine monthly pCO(2) anomalies. These are used in combination with monthly anomalies of sea surface temperature (SST) to investigate inter-annual variations of SST and pCO(2). Monthly anomalies of SST (as intense as 2 degrees C) are apparent in the CS, STZ and SAZ, and are indicative of strong inter-annual variability that seems to be related to large-scale coupled atmosphere-ocean oscillations. Anomalies of pCO(2) normalized to a constant temperature are negatively related to SST anomalies. A reduced winter-time vertical input of dissolved inorganic carbon (DIC) during phases of positive SST anomalies, related to a poleward shift of westerly winds, and a concomitant local decrease in wind stress is the likely cause of the negative relationship between pCO(2) and SST anomalies. The observed pattern is an increase of the sink for atmospheric CO2 associated with positive SST anomalies, although strongly modulated by inter-annual variability of wind speed. Assuming that phases of positive SST anomalies are indicative of the future evolution of regional ocean biogeochemistry under global warming, we show using a purely observational based approach that some provinces of the Southern Ocean could provide a potential negative feedback on increasing atmospheric CO2.

Dans l'enseignement des activités physiques, les réactions de l'enseignant à la prestation des élèves (feedback) constituent l'une des variables déterminantes dans la réussite pédagogique. Les réactions à la prestation se caractérisent par une grande variabilité interindividuelle. Leur émission fait suite à un processus comportant deux phases: le diagnostic et la prescription. Afin de mettre en évidence le rôle exercé par les facteurs liés aux caractéristiques de l'enseignant sur celles de leurs interventions, nous avons comparé les réactions à la prestation émises par 12 éducateurs physiques lors d'une séance d'enseignement simulé. Grâce à cette technique vidéo, les sujets réagissent à partir de performances motrices identiques. Les feedback ont été comparés entre quatre groupes de sujets caractérisés par des niveaux d'expérience sportive et pédagogique similaires. Une analyse factorielle par correspondance a permis d'identifier des classes de sujets émettant des feedback de même type. Les résultats tendent à souligner que (1) le niveau d'expertise dans la pratique de l'activité enseignée exerce une influence sur la première de ces phases; (2) le degré d'expertise pédagogique contribue à améliorer l'émission du message.
