The Summary of the Principle of Optimal Diversity of Biosystems

The paper summarizes the principle of optimum diversity of biosystems, which suggests that biodiversity is a parameter to be optimized. In fact, diversity is considered as a major adaptation of biosystems to environmental conditions. Paper discusses the diversity of two hierarchical levels - population (phenotypic diversity within a population) and coenotic (number of species in community). Нypotheses about mechanisms of diversity optimisation in the ecological, microevolutionary and evolutionary processes and findings for environmental management and biodiversity conservation are considered.

Diversity and Ecology of Parthenium weeds at Head Khanki, Pakistan

Biodiversity has traditionally emphasized on the distribution and variation of all species on earth. Biodiversity is both essential for our existence and intrinsically valuable in its own right. When species are moved to new locations that offers conditions for life similar to their native habitats, they may exploit vacant ecological niches and grow quickly, especially if they have no natural predators in their new settings. We also want to promote a sense of urgency for the need to protect wetland diversity.

Organic Uniformity?

Diversity (biological, cultural and social) is an important aspect of, and contributor to, resilience of social-ecological systems. However, diversity in agriculture is increasingly lost, and also in organic agriculture, where diversity is ethically required, there is increasing concern about low diversity. This exploratory study investigated organic farmers’ perception of diversity and which extrinsic and intrinsic factors influence agricultural diversification and agro-biodiversity. To do so, it employed qualitative interviews with organic farmers in Upper Austria, in which leverage points are identified, that might help to develop strategies for improving diversity on farms and in the food system. It is shown that farmers’ connotations with the term diversity are rich and manifold and encompass different aspects and elements of planned and associated biodiversity as well as social and economic aspects. The analysis of influencing factors on several aspects of biodiversity showed that personal, economic and production-technical factors determine agricultural diversity. It is shown that social diversity on the farm, direct marketing and cooperation are leverage points for increasing agricultural diversity on the farm level and thus should be considered and focused on in attempts to increase biological and agricultural diversity on (organic) farms.

Plant-biodiversity at Ajmiriganj Haor Homesteads of Bangladesh

Biodiversity is the contraction of biological diversity. Plant-biodiversity is the most important component of total biodiversity. ‘‘Biodiversity” is the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part. It includes diversity within species, between species and of ecosystem. Plant-biodiversity is the plant genetic wealth of a country. Economically and genetically important materials selected by both human and nature, adapted in the environment are the components of homesteads. Homesteads are the in situ conservation sites of wide range of plant-biodiversity. Environmental variations offer unique opportunity to select appropriate genotypes at different regions. Diversity of genes within plant species increases its ability to adapt in adverse environment. Any decrease in genetic variability may lead to ecosystem instability. Plant biodiversity is instrumental to cycling and recycling of nutrients and thereby achieving the stability of the ecosystem.

Biodiversity is a fairly new word to our language, but it is becoming more and more commonly used and understood. It simply signifies the variety of life on earth in all its shapes and sizes- from smallest insect and fungus to the largest mammal or tree. This massive variety of life is everywhere, not just in our countryside and gardens, but also in our towns and cities. It is all encompassing-biodiversity enriches all our lives, whether it’s a butterfly visiting our garden or a blackbird heard from an office window. Biodiversity contributes to our overall economy by supplying the raw materials for our clothing, food, drink, fuel, buildings and roads. Tourism based on wildlife is one of major income-earners. Environment-based jobs include farming, fishing and services providing water, energy and building materials. More than just the trees, forest biodiversity encompasses the multitude of plants, animals and micro-organisms that inhabit forest areas and their associated genetic diversity. Forest biodiversity can be considered at many different levels, including ecosystems, landscapes, species, populations and genetics.

Agriculture and Biodiversity Response, Mid-Zambezi Valley, Zimbabwe

This study was carried out in the semi-arid mid-Zambezi valley, northern Zimbabwe to explore how biodiversity respond to loss of primary habitats. The study investigated the impact of woodland conversion for cultivation purposes on woody species, arthropods and vegetation recovery. Cultivation is resulting in rapid decrease in tree diversity at farm level, while at landscape level agricultural activities do not have any effect woody species diversity however, there are negative effects on tree physiognomy and dominance. Arthropod indicator groups, Charaxes butterflies and Cetoniinae beetles, showed a decrease in abundance and loss of diversity due to agriculture with more loss recorded in homogeneous intensively cultivated areas. Recovering fallow vegetation was characterised by dominance of invasive species such as Acacia tortilis subsp spirocarpa. To conserve biodiversity within agricultural landscapes in this area effort may have to focus on implementing an agricultural paradigm that maintains a mosaic of different land-use units, each in a different phase of clearance-cultivation-abandonment-recovery-clearance cycle.
Jackfruit Diversity Jackfruit Diversity Новинка

Jackfruit Diversity

Jackfruit considered as the world''s largest fruit does not enjoy its due respect at present. The fruit is not popular among the masses as it is not easy to eat out of hand owing to difficulty in separating fruit bulbs from rind, and also due to morphological and/or biochemical hindrances associated with the fruit. Processing and product diversification in jackfruit is thought to help in popularizing the fruit. A wide diversity among jackfruits is seen in the Western Ghats of India, which is considered as the center of its origin. Western Ghats, the treasure house of diversity for jackfruit, provides ample opportunities for survey, collection and evaluation of fruit quality for dessert and processed products and to identify the types suitable for different purposes to augment its use as food. The exploration should help throw some light on jackfruit diversity, its physico-chemical aspects for using the fruit for dessert and processing purposes. The study should be especially useful to the academicians, researchers and students in horticulture, agriculture, biodiversity, food processing or anyone else who may be considering such under-utilized fruit crops.

Impact of CF on biodiversity conservation on lowland of Nepal

Nepal is a pioneer country to implement community forestry development programme under decentralized forest policy regimes in the world. Community managed forests (CFs) and government managed forests/national forests (NFs) are widely adopted systems in Tarai that has diverse socio-political and biophysical contexts. By 2008, one-third (34.6%) of total forest areas were handed over to local communities for managing forest resources through collective efforts in order to conserve biodiversity, reduce poverty and sharing forest benefits among the users households . It is crucial to assess whether ownership change from NFs to CFs affects to increase overall forest biodiversity. This paper aims to assess the diversity and dynamics of tree species at a landscape level in Western Tarai of Nepal. Biodiversity indices of tree species were measured using Shannon-Weiver diversity index (SDI) and Margalef species richness index (SRI) adopting simple random sampling techniques. The findings of study suggest that CFs are superior in terms of SDI than that of NFs while there was no significant difference in terms of SRI.

Microsatellite analysis in Chicken Microsatellite analysis in Chicken Новинка

Microsatellite analysis in Chicken

Chickens are agriculturally important animals and valuable model organism. Many inbred lines of chickens are well characterized for disease resistance and production traits. In general, biodiversity can be described at several levels from phenotypic observations to molecular data. Recent advances in molecular technology have opened up new horizons in assessment of genetic variability at the DNA level. Microsatellites are a group of DNA markers which are widely used to study genetic biodiversity in chicken. In present book, at first, we have reviewed application of different DNA markers in studying biodiversity in chicken; then different microsatellite markers have been used to study among and within genetic diversity of six Indian chicken populations. This book can be especially useful for students and researchers who are willing to know microsatellite analysis in chicken more in details.

Biodiversity of Arthropods in Bhendi, A. esculentus L. Ecosystem

Agriculture is now showing conspicuous signs of faltering because of a breakdown in the services provided by nature. Industrialised agriculture, in striving for greater levels of productivity, uses inputs such as pesticides and fertilisers to replace natural processes and causes pollution, health hazards and resistance development in pest populations. The role of biodiversity in pest management is a burgeoning area of research and forms of ecologically based pest suppression are important examples of the ecosystem services that can be provided by biodiversity. Moreover, pest suppression can be achieved concurrently with providing other benefits such as pollinator enhancement, natural enemies conservation, dual crop production and even carbon sequestration. In this book we have inventorized a total of 127 arthropod fauna, comprised of 112 insect species under 106 genera, 56 families, 10 orders and 14 species of spider and a species of mite.The biodiversity indices in bhendi or okra (Abelmoschus esculentus (L.) Moench) was not reported earlier and henceforth we hope that the book will stand as a base for further research in the biodiversity of arthropods in bhendi ecosystem.

Diversity and critical reflective work behaviour Diversity and critical reflective work behaviour Новинка

Diversity and critical reflective work behaviour

In this empirical study it was hypothesized that visible diversity and education level (diversity) are positively related to cognitive diversity and critical reflective work behaviour. But that in order to harvest the benefits of diversity, beliefs of valuing diversity are needed. Gender diversity and the average level of education within a team are found to increase the level of cognitive diversity. Analyses further revealed significant effects of task complexity and sector influences regarding critical reflective work behaviour. However, cognitive diversity did not resulted in more critical reflective work behaviour within teams. Therefore the moderating role of diversity beliefs could not be examined. The promise of diversity could not be demonstrated and more research is needed to provide more insight in the reality of diversity. Future recommendations are made and practical implications for organisations are given.

Conservation of Biodiversity in Pyrus Germplasm

Pear belongs to genus Pyrus, abundantly found in temperate region of AJ & K reflects rich biodiversity. Such diversity and valuable genetic resources are being eroded due to human over exploitation, and natural calamities. Keeping in view existing genetic diversity and genetic erosion in Pyrus germplasm, the focus of present study was to develop biotechnological conservation strategies by using slow-growth techniques. However in vivo preservation was also implemented to conserve the basic stock under field conditions. The apical shoots of nine pear genotypes were preserved in vitro under minimal growth conditions using low temperature treatments, modification in medium strength and adding mannitol in the basal medium and also by reducing the concentration of BAP and using growth retardants for different storage periods i.e. 3, 6, 9 and 12 months. After twelve months of storage, the culture successfully regenerated into new shoots and they were morphologically similar to those of non-stored.

ECONOMICS OF AGRICULTURAL BIODIVERSITY

Ricebean (Vigna umbellata) belongs to the group of underutilized plant species which survive because they are still useful to local people and occupying special niches in production systems because of their adaptability to low input and marginal lands. They are continue to be grown and managed particularly in rural areas of developing economies, and are thus contributing to the livelihood of the poor. They are locally plentiful but globally rare, scientific information and knowledge about them is little, and their current use is limited related to their economic potential. Landraces and their wild relatives are the key element of agricultural biodiversity and constitute a key resource maintained and used by farmers in different production environments. Maintenance, utilization and management of this diversity in the field are vital for sustainable agriculture. Commercialization and diversification of ricebean products and linking these products to the market not only gives an economic return to farming communities but also contribute to conserve biodiversity for future. This book would be useful to all those interested in the field of agricultural biodiversity.

Climate change : Effects on Biodiversity of Freshwater Fauna

The perspective of climate change and its direct affects on freshwater resources and indirect affects on diversity of fish fauna and freshwater micro-fauna such as zooplankton was presented here. North-eastern India- a mega biodiversity hot spot is considered as a natural resource of observation. Two key environmental parameters such as temperature and rainfall have been investigated in relation to climate change in North-eastern India in general and Tripura in particular. During a period of 28 years from 1982 to 2010 the atmospheric temperature is increased- 17.2-22.12 0C with average increase-0.2 0C per year. Rainfall is decreased from 162 mm to 37 mm, with average decrease- 3.34-5.26 mm per year. Data of CO2 at 0530 hrs shows a mean value- 17.27±6.43 ppm. Hence,data of climate change is relatively greater. Diversity of freshwater fish species in the freshwater ecosystem is reduced to 67 species from 146 species of 1982. Therefore,gradual decrease of rainfall as well as increase of temperature and CO2 over a period of three decades are the results of climate change in freshwater environment of North-Eastern Indian region.

Biodiversity Conservation in the Horn of Africa

In the book the biodiversity conservation status, problems, efforts and prospects in parts of the Horn of African countries representing Djibouti, Eritrea, Ethiopia and Somalia are reviewed. The ever-growing human population of >100 million, and various socio-economic, environmental and cultural issues are indicated as challenging the implementation of biodiversity conservation programs in this region. This region has diverse types of ecosystems such as highlands, Afro-alpine, lowlands, deserts and coastal areas with varied topography, and vegetation types correlated with the level of precipitation in the respective areas. The biodiversity of the Horn of African region is also endowed with high level of endemism. Two biodiversity hotspots, viz., the Horn of Africa biodiversity hotspot and the Eastern Afro-montane biodiversity hotspot occur in the region. Over 1,300 plants and animals species of the region listed in the IUCN red list categories. Many of the biodiversity resources of the region have high potential for human use. However, detailed studies on the biodiversity resources of the Horn of Africa region and its conservation are yet to be undertaken.
