Duck conservation strategy based on genetic characteristics has been undertaken to preserve indigenous breeds and produce high quality offspring. In addition, the genetic characteristic analysis provides further information for studying avian influenza viruses. The aim of this research was to study the genetic characterisation of indigenous Central Javanese duck in Indonesia using microsatellite markers. Microsatellite or simple sequence repeats (SSR) or short tandem repeats (STR) of various breeds of Central Javanese duck were analysed on 35 local ducks which consisted of seven variants of Javanese ducks in Central Java. Ten pairs of duck microsatellite primers were used to amplify the DNA from feathers. Nine out of 10 microsatellite loci (90%) demonstrated polymorphic patterns containing 50 alleles. The number of alelles varied from two to 10 alleles at various polymorphic microsatellite loci with an average of 5.56 alelles per locus. From the study, CAUD013 locus was determined as the highest heterozygosity with 0.882 score while CAUD030 locus was the lowest one with 0.034 score.Similarly, CAUD030 locus had the lowest PIC score (0.30) whereas the CAUD013 locus had the highest PIC value (0.869). Hence, it was showed that microsatellite markers were highly polymorphic in several loci for the Central Javanese duck and may be useful for genetic description of other native duck in terms of species conservation.

ABSTRACTDesigning an effective conservation strategy requires understanding where rare species are located. Although species distribution models are primarily used to identify patterns at large spatial scales, their general methodology is relevant for predicting the occurrence of individual species at specific locations. Here we present a new approach that uses Bayesian networks to improve predictions by modelling environmental co-responses among species. For species from a European peat bog community, our approach consistently performs better than single-species models, and better than conventional multi-species models for rare species when calibration data are limited. Furthermore, we identify a group of “predictor species” that are relatively common, insensitive to the presence of other species, and can be used to improve occurrence predictions of rare species. Predictor species are distinct from other categories of conservation surrogates such as umbrella or indicator species, which motivates focused data collection of predictor species to enhance conservation practices.

The Creation

This paper, which has been nearly a decade in gestation, describes the contribution that industrial development makes to the conservation of wild plants in Britain. It challenges the priorities of the British conservation movement in concentrating its efforts on rare species and habitats, on the creation of Nature reserves, and on the maintenance of rare species as rare species. A more positive approach is now advocated, stressing the need to prevent common species from becoming rare, the creation of new habitats, and the propagation and reintroduction of uncommon species.Whilst species conservation is relatively easy to justify and comprehend, habitat conservation is considerably more difficult. ‘Industrial habitats’ may be defined as those derived from any industrial process (including transport routes). Such habitats are characterized by a complex association and interaction of slope, aspect, drainage, nutrient status, and the chemical and physical characteristics of the skeletal soils—all of which are apt to change markedly over very short distances. In addition they are generally open, lack stability, do not receive frequent applications of fertilizer and/or herbicide, and are often inaccessible or well protected.
