A targeted nurturing of oak in the canton of Argovia goes against the natural development of forest stands where the dominant, naturally occurring species is beech. Because of this,afforestation with oak is both work intensive and costly and is therefore concentrated on sites where silvicultural, economical and ecological aspects have been taken into account. With the help of a simple model showing areas where, above all,oak is nurtured, comprehensively mapped forest stands were classed according to competitiveness and correlated to thermal levels, that represent an important site factor for oak. One important aspect surrounding the issue is the preservation of genetic resources and an adequate supply of appropriate seed from chosen autochthonal, indigenous oak stands. In addition,the endangered population of middle spotted woodpecker,which is tied to widespread sites of aged oak-rich deciduous stands, should be fostered. Taking ecological priorities into account a possible area to nurture oak has been demarcated in the Fricktal.

Glucosinolates (GSLs) are sulfur-containing secondary metabolites naturally occurring in Brassica species. The purpose of this study was to identify the GSLs, determine their content, and study their accumulation patterns within and between leaves of kimchi cabbage (Brassica rapa L.) cultivars. GSLs were analyzed using UPLC-MS/MS in negative electron-spray ionization (ESI−) and multiple reaction monitoring (MRM) mode. The total GSL content determined in this study ranged from 621.15 to 42434.21 μmolkg−1 DW. Aliphatic GSLs predominated, representing from 4.44% to 96.20% of the total GSL content among the entire samples. Glucobrassicanapin (GBN) contributed the greatest proportion while other GSLs such as glucoerucin (ERU) and glucotropaeolin (TRO) were found in relatively low concentrations. Principal component analysis (PCA) yielded three principal components (PCs) with eigenvalues ≥ 1, altogether representing 74.83% of the total variation across the entire dataset. Three kimchi cabbage (S/No. 20, 4, and 2), one leaf mustard (S/No. 26), and one turnip (S/No. 8) genetic resources were well distinguished from other samples. The GSL content varied significantly among the different positions (outer, middle, and inner) of the leaves and sections (top, middle, bottom, green/red, and white) within the leaves. In most of the samples, higher GSL content was observed in the proximal half and white sections and the middle layers of the leaves. GSLs are regarded as allelochemicals; hence, the data related to the patterns of GSLs within the leaf and between leaves at a different position could be useful to understand the defense mechanism of Brassica plants. The observed variability could be useful for breeders to develop Brassica cultivars with high GSL content or specific profiles of GSLs.

AbstractThe naturally occurring weevil (Curculionidae) fauna of Dade and Monroe counties in southern Florida is composed of 100 genera and 222 species. Another 20 species are adventive; their presence is due to the unintentional action of humans. Twenty-eight species occur only on the islands of the Florida Keys, 118 species occur only on mainland south Florida, and 76 species are shared by the mainland and the islands. Greater habitat diversity on the mainland accounts for its higher species diversity. The species distributions and faunal affinities are 60% Nearctic and 40% Neotropical or West Indian. Thirty-five species are known to occur only in southern Florida. This probably reflects poor knowledge of their distribution in the Caribbean rather than southern Florida as an important site for species origin. Most of the weevil species (133; 60%) are habitat specific and few species (22; 10%) are found in three or more habitat types. Wetland-inhabiting species are predominant (76; 34%), followed by hardwood hammock species (47; 21%). Flightlessness in adults is uncommon (35 species; 16%), but more prevalent in the species endemic to southern Florida (12 species; 34%). Extrapolation from data on weevil diversity yields a conservative estimate of over 5000 species of insects in southern Florida.

Three distinct bark patterns of American beech (Fagus grandifolia Ehrh.) were exhibited by trees growing in naturally occurring forest stands in New Hampshire, U.S.A. Consistent differences in periderm anatomy were found to be associated with each particular bark pattern. Two patterns were typical of trees which maintained the first periderm in a superficial position. Another bark pattern is interpreted as being the result of normal rhytidome development, an uncommon occurrence in American beech.

Eligibility Requirement

This article discusses limitations on patenting inventions based on marine genetic resources of areas beyond national jurisdiction. First, it considers that patent protection for these inventions is compatible with losc. Next, it propounds that to further equitable access to new knowledge of the genetic resources, patentability requirements should be shaped to reward human creativity in applying discoveries only. Accordingly, discoveries of naturally occurring dna sequences and the like from the genetic resources should be deemed as a “familiar part of prior art” and that other inventive concepts should be required to meet the patent eligibility requirement. Finally, it contends that it is not justified to require patentees to share any benefits derived from the utilization of inventions based on the genetic resources of the Area.

The rabbit (Oryctolagus cuniculus) is a unique multipurpose domestic species that has relevant economic impacts in several contexts. This review is focused on rabbit genetic resources that have been mainly bred for the fixation of differentiating features (e.g., exterior traits) that have been already genetically characterized. Several naturally occurring rabbit mutants could be useful as animal models for the investigation of the biological mechanisms determining their characterizing aspects, with translational potentials. A historical overview of the origin of the domesticated rabbit populations and of their genetic differentiation into many breeds is summarized. Then, a detailed analysis of the genetic features that characterize the different breeds is reported, starting from coat color and coat structure affecting genes (MC1R, ASIP, TYR, MLPH, TYRP1, KIT, LIPH, and FGF5), determining major loci described by classical genetic studies. Mutations in these genes have implications in pigmentation features, hair growth, and related defects. Other gene mutations affecting body size or shapes (HMGA2) and other physiological disfunctions (RORB and BCO2) are also described Additional studies are needed to complete the genetic characterization of some of these loci and to investigate the large genetic variability available in fancy breeds and commercial meat and fur lines.

Middle Spotted Woodpecker

The middle-spotted-woodpecker Dendrocopos medius, which was deemed to have disappeared from the littoral of Neuchâtel,is a species in full expansion today, particularly in the Bois du Devens (MULHAUSER & BLANT en prép.). Without differentiated silvicultural interventions-i.e. differentiated according to area-today this region would be dominated largely by the beech. The article presents the evolution of the forest Bois du Devens, the development of silvicultural practice during the 20th century and its effect on the expansion of the middlespotted-woodpecker. The analysis of the silviculture practised in this forest since 1920, fleshed out with the numerical basis of the silvicultural inventories, provides confirmation of the dependence of the middle-spotted-woodpecker on oaks of major dimensions, with a preference for highly fertile habitats and underlines the importance of mature forest stands. Such heterogeneous stands are rich in microstructures, cavity trees,big trees, trees that accomplish their full life cycle, as well as entire crowns that are left on the ground after trees have been cut.
