The impact of forest fragmentation on genetic diversity of Pachycondyla obscurans, a predatory forest-specialist ant species, was investigated in six forest locations using Amplified Fragment Length Polymorphism (AFLP) fingerprinting. There was little difference in genetic diversity between three large forest locations (two locations in continuous forest, plus one 120,000 ha fragment) and three small forest fragments (151-320 ha). Populations from two locations ~60 km apart in continuous forest...
In fact, wind energy is the kinetic energy of air masses in the atmosphere. So it can be argued that the wind energy, the same as the wave energy, is a form of solar energy, which will be available for mankind as long as there will be sun and our planet (Ostertag 2001). Every hour the Earth receives 100 000 000 000 000 kW/h of solar energy. About 1-2% of solar energy is converted into wind energy. This figure is 50-100 times bigger than the amount of energy converted into biomass by all plants...
Nowadays, there is a big problem in the area of the waster crisis. Many countries feel the lack of fresh water for their people and develop programs considering the issue. There are many reasons why our freshwater supply is shrinking. Among them are over population of the planet, pollution and contamination of our freshwater. Many countries set laws and regulations to protect their vast supply of freshwater, for example Canada.A water crisis is the temporary interruption in the distribution of...
It is the nature that gives us the resources, to own the plushest homes, state of the art offices, jazziest cars, grooviest clothes and the shiniest of gadgets. But at what price to the planet? Environmental /green innovations are the need of the day to unleash the innovation potential to create sustainable development pathways for future.Some of the latest green inventions, technologies, processes are exciting, offbeat and they don't cost the Earth! Here's a look at the Top 5 Environment...
Climate change starts with our atmosphere. The combination of gases surrounding with the earth without which this planet would be a large lifeless sphere and people wouldn't exist. While many process in the earth occurred naturally it is the measured rate at which some are changing and that is the measure case of concern. Scientists have long known that the presence of atmosphere keeps the surface of the planet warmer than it would be without the atmosphere. [1]In fact without the atmosphere...
The search for sustainable and renewable alternative sources of energy is getting more focused worldwide. Nations are putting energy generation on a higher priority than before. Solar energy is a leading contender for assisting nations with meeting their energy needs, while contributing to fulfilling their responsibilities of reducing the carbon footprint in the energy generation process. The hypothesis of this study is that it is feasible to use solar cells globally for generating energy. A...
From your readings and our field trip, in your own words explain what CRP, CREP and WHIP programs are. Explain how they can benefit wildlife conservation. Discuss some of the shortcoming to these programs and provide some suggestion to improve their ability to conserve wildlife in agricultural landscapesConservation Reserve ProgramThe program is administered by the USDA's Farm Service Agency. The Conservation Reserve Program (CRP) is a voluntary partnership program between the Federal...
From the simplest touch to the most complex chemical reaction, electromagnetism is at work. From the most rudimentary compass to the most advanced supercomputer, electromagnetism is at work. From the magnetosphere's deflection of cosmic rays to the ionosphere's reflection of radio-waves, electromagnetism is at work.Michael Faraday and Heinrich Henry performed lots of experiments to learn about the connection between electricity and magnetism. The results of these experiments have led to the...
Nowadays, it is noticed that the Earth’s temperature is increasing more than the last years, where humans caused most of the earth warming by releasing heat-trapping gases as we power our modern lives, the result is called Global Warming.I am interested in this subject because I would like to know what Global Warming is, is it relate it to the whole in the ozone layer, how Global Warming affects our life, and what we can do about it.Firstly, global warming will be introduced...
Nigerians, like many other Africans, believe that certain fruits like orange only grow in particular seasons. This cannot be any further from the truth. In developed countries, most if not all the fruits are available for consumption all year-round. The secret behind this availability of fruits is not so far-fetched. This write-up is focused on year-round orange production in rural Nigeria. Growing oranges demands the maintenance of certain climatic conditions like temperature and wind...
