Biological species concepts


Species

Smallest independently evolving unit

Independent evolution occurs when mutation, selection, gene flow, and drift operate independently in different populations

Therefore, these species will follow independent evolutionary trajectories

Potentially 23 different species concepts

Biological Species Concept (BSC)

Species are groups of actually or potentially interbreeding natural populations that are reproductively isolated ....etc

Biodiversity

Biodiversity is the variety and differences among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part.
It is virtually synonymous with Life on earth .
Biologists most often define biological diversity or biodiversity as the totality of genes, species, and ecosystems of a region.
The biodiversity found on Earth today consists of many mill ....etc

1. Introduction
Roadside Verges have long been known to be valuable ecologically, although their intrinsic importance can also be very variable. They can provide a locally significant wildlife resource in themselves as well as provide wildlife corridors connecting sites within otherwise impoverished biodiversity landscapes. It has been estimated that there are 3000km of verges in Hertfordshire. However, in order to effectively look at the issue of the wildlife importance of roadside verges, a number of aspects need to be considered. These inc ....etc

ABSTRACT
Since two-three decades, hydrogen has been identified as a versatile potential fuel competent to the conventional fuel such as gasoline. In order to implement it fully and to develop the combustion based power devices which may supply much higher energy density than others, the understanding of hydrogen air combustion mechanism is very essential. In this seminars, Computational Fluid Dynamics (CFD) based numerical simulations have been performed to study the combustion of non-premixed hydrogen-a ....etc

Prospects of Cane and Bamboo to Develop Entrepreneurs as agro-based Small Scale Industries of Assam

ABSTRACT
India has the largest attentiveness of rural population then any other country of the world. Assam is endowed with vast natural and human resources but we have failed to utilize all the natural and human resources properly due to the lack of latest technology skills, training and Information. There are tremendous prospects of Cane and Bamboo based small scale industries in the entire north-east regi ....etc

I INTRODUCTION

1. Tuber Crops
Tuber crops are the third most important food crops of man after cereals and grain legumes. These are a group of plants which produce underground plant parts which are storage in function. They are mainly classified into two:

1. Major tropical tuber crops
2. Minor tuber crops

The major tropical tuber crops grown in our country are cassava, sweet potato, yams & aroids. The minor tuber crops include coleus, Pachyrrhizus, arrow root etc. These tubers are rich source of carbohydr ....etc

Reduction Of Alcohol Intoxication In Experimental Animals By Resveratrol
Parvathy S. Nair & Parvathy R.
S8 Biotechnology & Biochemical Engineering
Mohandas College of Engineering & Technology, Anad



Abstract
Chronic alcohol consumption induces an increase in oxidative
stress. As polyphenolic compounds are potent
antioxidants, the experiment was aimed to examine whether dietary supplementation of resveratrol (a polyphenol)
may attenuate lipid peroxidation, ....etc

study of pollination in sunflower and legume project

Abstract
Cratylia argentea is a high-quality forage legume shrub, with particular potential for the subhumid tropics owing to its adaptation to acid and infertile soils and drought tolerance. However, lack of knowledge about the ability of this species to self-pollinate makes purity maintenance of accessions difficult. Studies were conducted to investigate whether the gametes of C. argentea flowers
are self-compatible, and to verify the dependence of reproduction on insects. Pod set and seed ....etc
