It is well known that the Kingfisher populations decrease dramatically after a sever winter. The recovery depends on the climatic conditions of the next reproductive seasons. In order to understand the mechanism involved in this climatic influence, the fate of more than 500 broods was studied between 1985 and 1993. The study area comprises the river Meuse from Vireux (F,08) downstreams to Huy (B Liège) and the lower part of its main tributaries. The first egg laying date was determined for each brood, eggs were counted, pulli ringed at nest and the adults controlled and ringed when possible. Our main conclusions are i : the beginning of the first clutch is correlated with the thermic conditions of March. ii : the clutches are not synchronised, even on a same watercourse. iii : the egg probuction and the hatching success don't show clear variations between years abd habitat types (river, ponds and small streams) or depending on the clutch rank. iv : the fledged young production depends on how much broods are raised by the different pairs. v : the probability a pair is attempting a thrid brood is function of how early the first clutch is layed, the age of the male (older males settle earlier and are more productive), the habitat quality and the weather conditions (rain, temperature) in May.

The study was conducted with 150 Fulani herders in the departments of Borgu and Alibori in Benin. It aimed to determine the zootechnical parameters of traditional cattle farms. The survey collected information on the characteristics of cattle herds. The results showed a high proportion of females (76%), an average herd size (66 animals) and the prevalence of the Borgu breed (86%). The herds also showed a low breeding performance, characterized by a high calf mortality rate (10%), and low reproductive parameters (64% calving and fertility rates). In a year, 0.57 calf was weaned on average by its dam. The low performance of cattle farms in coastal countries such as Benin is consistent with that of pastoral areas, which is complementary in terms of meat supply to West African markets. [less ▲]

We herein describe the development of a biochemical method to evaluate the effect of single nucleotide polymorphisms (SNPs) in target genes on their regulation by microRNAs in vivo. The method is based on the detection of allelic imbalance in RNAs coimmunoprecipitated with AGO proteins from tissues of heterozygous individuals. We characterize the performances of our approach using a model system in a cell culture, and then apply it successfully to prove that the 3'UTR g+6223G-->A mutation operates by promoting RISC-dependent down-regulation of myostatin (MSTN) in skeletal muscle of Texel sheep.

The identification of nonlinear dynamic systems is increasingly becoming a necessary part of vibration testing and there is significant research effort devoted to it. However, as the current methodologies are still not suitable for the identification of general nonlinear systems the subject is very rarely introduced to undergraduate students. In this paper, recent progress in developing an expert approach to nonlinear system identification is used in order to demonstrate the subject within the context of an undergraduate course or as an introductory tool for postgraduate students. The demonstration is based around a software package of an Expert System designed to apply systematically a wide range of identification approaches to the system under investigation. It is shown that the software can be used to demonstrate the need for nonlinear system identification, the complexity of the procedure, the possibility of failure and the good chances of success when enough physical information about the system is available.

Alcelaphine herpesvirus 1 (AlHV 1), carried by wildebeest (Connochaetes taurinus) asymptomatically, causes malignant catarrhal fever (MCF) when cross species transmitted to a variety of susceptible species of the Artiodactyla order. MCF is a fascinating disease described as a combination of lymphoproliferative and degenerative lesions. The study of MCF pathogenesis has been impeded by an inability to produce recombinant virus, due mainly to the fact that AlHV 1 becomes attenuated during passage in culture. Here, we have overcome these difficulties by (i) cloning the entire AlHV 1 genome as a stable, infectious and pathogenic bacterial artificial chromosome (BAC), and (ii) by using prokaryotic recombination technology for the production of an AlHV 1 recombinant. Firstly, the AlHV 1 genome was BAC cloned using one insertion site in a region containing no open reading frame. This insertion allowed the production of an AlHV 1 BAC clone stably maintained in bacteria and able to regenerate virions when transfected into permissive cells. BAC derived AlHV 1 virions induced MCF in rabbits comparably to the AlHV 1 wild type (WT) strain. Secondly, a two step mutagenesis procedure in E. coli was used to generate a recombinant strain expressing enhanced-green fluorescent protein (EGFP) as a reporter gene. After reconstitution of recombinant virions into permissive cells and excision of the BAC cassette, flow cytometry analyses were performed to validate the recombinant strain and to investigate the pathogenesis of MCF. The results of these analyses can be summarized as follows: (i) the validity of the EGFP expression cassette as a reporter gene has been demonstrated by in vitro infections; (ii) inoculation of rabbits revealed that the recombinant strain has retained the pathogenicity of its parental strain and that the cell types carrying AlHV-1 in peripheral blood mononuclear cells, lymph nodes and the spleen are mainly CD5+ CD8+ cells.
