Conservation Policies

Gaps in biodiversity conservation management within the Conservation Area that are the responsibility of the central government and outside the Conservation Areas or as the Essential Ecosystems Area (EEA) which are the authority of the Regional Government, have caused various spatial conflicts between wildlife /wild plants and land management activities. Several obstacles faced by the Local Government to conduct its authority to manage (EEA), caused the number and area of EEA determined by the Local Government to be still low. At present only 703,000 ha are determined from the 67 million ha indicated by EEA. This study aims to overview biodiversity conservation policies by local governments and company perceptions in implementing conservation policies and formulate strategies for optimizing the role of Local Governments. From the results of this study, there has not been found any legal umbrella for the implementation of Law number 23/ 2014 related to the conservation of important ecosystems in the regions. This regulatory vacuum leaves the local government in a dilemma for continuing various conservation programs. By using a SWOT to the internal strategic environment and external stratetegic environment of the Environment and Forestry Service, Bengkulu Province , as well as using an analysis of company perceptions of the conservation policies regulatary , this study has been formulated a “survival strategy” through collaboration between the Central Government, Local Governments and the Private Sector to optimize the role of Local Government’s to establish EEA in the regions.Keywords: Management gaps, Essential Ecosystems Area (EEA), Conservation Areas, SWOT analysis and perception analysis

The role of the wild plants in relation to the conservation of the Indonesian insectpollinators was studied at several areas of Java. Three of direct observationmethods were applied: study of biodiversity and observation on the wild flowersand the insect pollinators as well, and the behaviour of the insects. The flowersof wild plants were relatively smaller and paler in colour, however they were moreattractive to insect pollinators than cultivated plants. Flowering time of the wildplants was mostly during wet seasons, contrary to that of the cultivated plantswhich was mostly during dry seasons. Our observation indicated that these wildplants are the food resources of insect pollinators during wet seasons. Observationdata support the importance of wild plants to supply food to insect pollinatorsduring wet seasons. Management of wild and cultivated plant environments isnecessary to conserve insect pollinators.

This chapter describes the methodology and results of the environmental archaeology research programme at Nicopolis ad Istrum in the Balkans. The aims of the research programme were: to determine the use of the major domestic animal and plant species and to explore what husbandry practices may have been employed; to examine the changing role of domestic versus wild resources; to reconstruct the likely natural environment close to Nicopolis, using the presence of particular species and their known habitats. This chapter presents examinations of epigraphic and documentary evidence found at the site, including coins and animal footprints. A large quantity of bio-archaeological data was collected, including bone fragments of mammals, birds, and fish; moderate quantities of terrestrial, freshwater, and marine mollusca; and large quantities of cereals, pulses, edible fruits, and nuts, as well as wild plants.

This paper presents the results of an experimental investigation undertaken to evaluate different extractant solutions viz. HCl, Mg(NO3)2, and DTPA with the range of concentration from 0.001 to 0.1Nafter incubation with group-IIB metals (Zn, Cd, and Hg) and EDTA to understand the capability to remove Zn, Cd, and Hg from soils. Two noncontaminated soils, one acidic (GHL) and the other alkaline (KAP), in reaction were taken from an agricultural field of West Bengal, India for this investigation. Experiments were conducted on these two soils spiked with ZnII, CdII, and HgIIin concentrations of 612, 321, and 215 mg/kg for soil GHL and 778, 298, and 157 mg/kg for soil KAP, respectively, which simulate typical electroplating waste contamination. The removal of Zn, Cd, and Hg in soil GHL within the range of HCl concentrations was 8.2–16.5, 12.2–19.1, and 4.3–6.9 whereas these were 6.5–7.6, 8.5–14.1, and 3.2–5.2 in soil KAP. The removal of Zn, Cd, and Hg in soil GHL within the range of Mg(NO3)2concentrations were 12.2–28.5, 19.1–24.6, and 18.2–19.1 whereas these were 9.1–12.1, 8.3–12.1, and 10.6–48.1 in soil KAP. For DTPA extractant, the percent removal of metal was found to be significantly higher than the other two extractants, which corroborates that DTPA is a better extractant for soil cleaning.

Begomoviruses are plant viruses that cause major losses to many economically important crops. Although they are poorly understood, begomoviruses infecting wild plants may have an important role as reservoirs in the epidemiology of viral diseases. This study reports the discovery and genomic characterization of three novel bipartite begomoviruses from wild and cultivated African basil (Ocimum gratissimum) plants collected in Uganda, East Africa. Based on the symptoms shown by the infected plants, the names proposed for these viruses are Ocimum yellow vein virus (OcYVV), Ocimum mosaic virus (OcMV), and Ocimum golden mosaic virus (OcGMV). Genome and phylogenetic analyses suggest that DNA-A of OcGMV is mostly related to begomoviruses infecting tomato in Africa, whereas those of OcYVV and OcMV are closely related to one another and highly divergent within the Old World begomoviruses. The DNA-A of all characterized begomovirus isolates are of a recombinant nature, revealing the role of recombination in the evolution of these begomoviruses. The viruses characterized here are the first identified in O. gratissimum and the first in Ocimum spp. in the African continent and could have important epidemiological consequences for cultivated basils and other important crops.

History Of

The role of natural enemies in the control of the pear psylla, Psylla pyricola Foerst., has been of minor importance in the published history of this pest in North America. Jensen (1957) listed six species of parasites that attack the pear psylla nymph, but only one, Psylledontus insidiosus Cwfd. (Hymenoptera: Encyrtidae), is recorded from North America. Slingerland (1896) stated that the predators Chrysopa oculata Say (Neuroptera: Chrysopidae) and Adalia bipunctata (L.) (Coleoptera: Coccinellidae) were observed in the field feeding on psyllid eggs, nymphs and adults. Georgalla (1957) reported that Anthocoris nemorum L. (Hemiptera: Anthocoridae) fed upon pear psylla eggs and nymphs, but made no reference to effect upon psyllid populations.

Julian Besag was an outstanding statistical scientist, distinguished for his pioneering work on the statistical theory and analysis of spatial processes, especially conditional lattice systems. His work has been seminal in statistical developments over the last several decades ranging from image analysis to Markov chain Monte Carlo methods. He clarified the role of auto-logistic and auto-normal models as instances of Markov random fields and paved the way for their use in diverse applications. Later work included investigations into the efficacy of nearest-neighbour models to accommodate spatial dependence in the analysis of data from agricultural field trials, image restoration from noisy data, and texture generation using lattice models.
