Description:
This work describes the ecological characteristics of the intestinal helminth communities of 50 wolves (Canis lupus L.) from Spain. The species found were classified into three groups according to prevalence, intensity and intestinal distribution. Taenia hydatigena Pallas, 1766 and Uncinaria stenocephala (Railliet, 1884) are the core species of the community. Taenia multiceps (Leske, 1780) is a secondary species. The rest of the species, Alaria alata (Goeze, 1782), Taenia serialis (Gervais, 1847), Taenia pisiformis (Bloch, 1780), Dipylidium caninum (Linnaeus, 1758), Mesocestoides sp. aff. litteratus, Toxocara canis (Werner, 1782), Toxascaris leonina (von Linstow, 1902), Ancylostoma caninum (Ercolani, 1859) and Trichuris vulpis (Froelich, 1789), behave as satellite species. The linear intestinal distribution of all helminth species was analysed. The location of most species can be considered predictable, especially for core and secondary species. The analysis of interspecific relationships between infracommunities shows that negative associations are more numerous than positive associations. The role of A. caninum in the community is compared with that of U. stenocephala.

Description:
Genes differentially expressed under high irradiance (HI) stress in mature flag leaves of super-hybrid rice Liangyoupeijiu (Oryza sativa ssp. indica) were studied by the silver-staining mRNA differential display technique. We obtained 167 differentially displayed bands on silver-stained polyacrylamide gels and searched for their genetic origins. Five cDNA fragments, which were upregulated by HI stress, were cloned and sequenced. The clones of G25×320, A31×380, and G29×280 putatively encode a cytosolic monodehydroascorbate reductase (MDAR), a phosphatidylinositol 4-kinase (PI-4-K), and a DEAH-box RNA helicase, respectively. Most differentially expressed genes in hybrid rice were inherited from parents and many of them were related with both parents, although some were derived from one parent only. The differentially expressed cDNA fragments having no distinct genetic origins indicated the involvement of some unclear mechanisms in the inheritance processes from parents to hybrid. and G.-Q.
