Benthic Macro Invertebrate As Biological Indicator Benthic macro invertebrates live in a wide variety of habitats and can be found from the smallest headwater streams down to the largest rivers. In general, benthic organisms are most diverse in the fast flowing riffle and run areas of streams. Compared to pools and glides, riffles and runs […]

Vertical Gardens: growing more in less space One of the gardening world’s hottest trends, “vertical gardens” allows plants to grow on walls and other non-horizontal surfaces. They’re especially popular for small-space gardening where ground is at a premium, or as decoration for patios and outdoor rooms. Putting plants at eye-level also gives new appreciation to

Methods of Micropropagation Micro-propagation is the practice of quickly multiplying stock plant material to produce a large number of progeny plants, using contemporary plant tissue culture methods. Micro propagation is used to multiply dignified plants such as those that have been genetically modified or bred through conventional plant breeding methods. It is also used to

Parasitic Leeches and Copepods on Fish Although not a common problem, occasionally, fish will be observed infected with either leeches or copepods. Leeches have long, slender flexible bodies and actively swim for an attack on their prey. Skin and underlying soft tissues are damaged and allow blood to flow into the leech’s digestive tract. Leeches

Carbon Sequestration Through Ecosystems Several Human activities, such as burning of fossil fuels such as coal, oil, and gas, have caused a substantial increase in the concentration of carbon dioxide in the atmosphere which results measurable global warming. All these activities posing adverse effects and responsible for sea-level rise, floods, droughts, increased wildfires, changes in

Effects of Enviornmental Temprature on Fruit Flies Drosophila melanogaster is a small, common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics and behaviour. Thomas Hunt Morgan was the pre-eminent biologist studying Drosophila early in the 1900’s. He was the first to discover sex-linkage and
