    Notes: Abstract The insect fauna in paddy fields is composed of resident, migratory and aquatic species each corresponding to the continuous cropping of rice in the same field, harvesting rice as an annual crop, and originating from still water habitats in wetlands. Although IPM is becoming popular in the control of rice pests, those ‘minor’ insects and aquatic insects that have no direct economic impact on rice production have received little attention. Consequently, some of them are in danger of extinction requiring conservation. A new concept, ‘Integrated biodiversity management (IBM)’, is proposed under which IPM and conservation are reconciled and made compatible with each other. As an operational concept in agroecology, premises for implementing IBM are suggested.

    Environmental economics of the Khangchendzonga National Park in the Sikkim Himalaya, India (2000)
    Springer
    GeoJournal 50 (2000), S. 329-337 
    Details
    ISSN: 1572-9893
    Keywords: contingent valuation ; bidding game ; biodiversity ; protected areas ; conservation

    Topics: Geography
    Notes: Abstract A contingent valuation survey was conducted involving local community members, domestic and foreign visitors to estimate the environmental economics of the Khangchendzonga National Park and to elicit their willingness-to-pay (WTP) for its maintenance and conservation. Using a random survey, the average WTP was US$ 8.84 for foreign visitors per visit, followed by US$ 6.20 per household per year by local community members and US$ 1.91 per domestic visitor per visit for improvement in environmental conservation. The WTP was strongly influenced by age, education and income. The present study demonstrated that the contingent valuation method (CVM) is a promising approach, however it lacks inclusion of non-monetary contributions. The WTP for environmental management by the local communities was mostly in kind or time for services. The CVM can be a useful tool for decision-makers regarding investment and policy purposes for management of biodiversity hot spots and protected areas in developing countries.

    Topics: Biology , Energy, Environment Protection, Nuclear Power Engineering , Ethnic Sciences
    Notes: Abstract Shifting cultivation (jhooming) has been identified as one of the main human impacts influencing biodiversity in Tripura, Northeast India. Over the last few years a new class of shifting cultivators has emerged that has adopted non-traditional forms of jhooming, which have been responsible for the loss of biological diversity in the state. This paper describes the successes achieved by the state government in providing the jhumias (tribes practicing jhooming) with various non-jhooming options. Recommendations include the need for short and long term control measures, improvement of existing jhooming methods, and integration of traditional knowledge with new practices.

    Notes: Abstract Genetic status and fluctuating asymmetry (FA) were assessed in a small, isolated and endangered population of the moth Dysauxes ancilla in Sweden. A sample from the German population, within the continuous breeding area of the species, was used for comparison. The levels of FA were significantly higher in the Swedish population, indicating a reduced ability to withstand developmental stress. Two polymorphic loci showed significantly higher variation in the Swedish population, indicating that there are no serious effects on genetic factors. Therefore, it is suggested that the increased level of FA in the Swedish population is due to the stress of living in an ecologically marginal habitat. The Swedish population is a northern outpost separated from the continuous distribution area of species and environmental stress caused by variable and extreme abiotic factors, for example climatic conditions, could explain a higher FA. However, it is still an open question if a higher FA from environmental stress also constitutes an increased extinction risk.

    Notes: Abstract The Norwegain mountains have had a central role in the subsistence agroecosystems by providing vast biological resources for humans and their livestock since 4000–3500 BP as indicated by paleoecological records. Later with the development of the summer farming system the use of the mountains was intensified. This long-term use of the mountains has shaped a montane cultural landscape by livestock grazing, mowing for hay, fuel collection and a variety of other uses. The result is a significant increase of the grassland areas at the expense of the forest. Those semi-natural grasslands and heathlands with specific biological diversity have until recently dominated the mountains but are today decreasing due to forest invasion – which in turn is a result of changes in human land use. The present paper focuses on changes in landscape pattern and differences in landscape development in two mountain valleys with summer farming activities, in Mid-Norway, over the period 1960s–1990s, and seeks to interpret the changes in relation to differential land use and environmental factors. This study contributes examples from human shaped ecosystems in mountains where the fragmentation of semi-natural habitats is addressed. A set of landscape pattern indices commonly used in landscape ecological studies is also used here, and their ecological relevance in the present context is dealt with. The implications of changed land use for biodiversity conservation in those mountains and the relationships to future sustainable agriculture is also briefly discussed.

    Notes: Abstract Populations of the Calafia pearl oyster Pinctada mazatlanica ofthe American Pacific coasts have been considered endangeredbecause of overfishing and/or alteration to coastal areas. Weassessed genetic variability and the pattern of populationstructure among 9 samples collected from Mexico to Panama, usingmtDNA RFLP analysis of two genes: 12S rRNA and subunit one ofCytochrome oxydase (COI). Haplotype diversity varied from 0.000to 0.856. The Panama population appeared to be monomorphic, whilethe other samples exhibited a level of haplotypic variabilitysimilar to those reported in the literature for the same kind ofanalysis on other bivalves species. A test for the impact ofdemographic history on genetic diversity was applied on thesequence data, and the results were congruent with a recentdecline of population sizes. Genetic differentiation was shown tofollow a scheme of isolation by distance, with low levels ofdifferentiation at the scales of ten to one hundred kilometres,whereas stronger and significant genetic structure was detectedat a larger scale. Three significantly distinct groups could thenbe defined, which correspond to Northern Mexico, Southern Mexico,and Panama.

    Gap analysis: concepts, methods, and recent results* (2000)

    Notes: Abstract Rapid progress is being made in the conceptual, technical, and organizational requirements for generating synoptic multi-scale views of the earth's surface and its biological content. Using the spatially comprehensive data that are now available, researchers, land managers, and land-use planners can, for the first time, quantitatively place landscape units – from general categories such as ‘Forests’ or ‘Cold-Deciduous Shrubland Formation’ to more categories such as ‘Picea glauca-Abies balsamea-Populus spp. Forest Alliance’ – in their large-area contexts. The National Gap Analysis Program (GAP) has developed the technical and organizational capabilities necessary for the regular production and analysis of such information. This paper provides a brief overview of concepts and methods as well as some recent results from the GAP projects. Clearly, new frameworks for biogeographic information and organizational cooperation are needed if we are to have any hope of documenting the full range of species occurrences and ecological processes in ways meaningful to their management. The GAP experience provides one model for achieving these new frameworks.

    Polyphyly of mtDNA lineages in the Russian sturgeon, Acipenser gueldenstaedtii: forensic and evolutionary implications (2000)

    Notes: Abstract Molecular species identification methods are an important component of CITES monitoring programs for trade in sturgeon and caviar. To date, obtaining molecular evidence for distinguishing caviar from four closely related Eurasian sturgeon species Acipenser baerii (Siberian sturgeon), A. gueldenstaedtii (osetra), A. persicus (Persian sturgeon), A. naccarii (Italian sturgeon) remains problematic. Using approximately 2.3 kb of mtDNA sequence data (cytochrome b, NADH5, control region), we find this to be attributable to the polyphyletic nature of these mitochondrial DNA markers in the Russian sturgeon, A. gueldenstaedtii. Two mitochondrial lineages are present within this species: one is phylogenetically affiliated with A. persicus and A. naccarii, while the other clusters with A. baerii. These findings have a direct impact on molecular testing of commercial caviar and demonstrate the necessity of using large sample sizes when constructing forensic databases. Furthermore, the results affect current taxonomic designations for these species as well as hypotheses concerning their evolutionary origins.

    Romania's Apuseni Mountains: Safeguarding a cultural heritage (2000)

    Notes: Abstract The Apuseni Mountains are unusual on account of the extreme fragmentation of the settlement pattern particularly in the upper Aries valley. Not only is hamlet settlement very much the rule, but these small units of settlement may be quite widely separated from each other by distance and altitude. Such networks have evolved through clearance of the high surfaces which cannot be efficiently farmed from the valleys in which modern infrastructure has been concentrated over the last century. Important questions therefore arise with regard to the survival capacity of communities which are critical elements in a cultural landscape that constitutes a valuable resource for both Romania and Europe. In other parts of the region dispersal is not so extreme, but there are still depopulation tendencies which are potentially damaging for the cultural landscape. The paper examines the lifestyles associated with outlying settlements and the extent to which centralising tendencies have been resisted in recent times. In the context of the present transition it considers the actions being considered to safeguard fragile mountain communities in a vulnerable area exposed to growing commercial penetration associated with cross-border cooperation on the Hungarian- Romanian frontier.
