Cheap sheds in Orrell are a great storage space for all your garden tools, potting soil and compost. If you are an avid gardener and like nothing better than pottering in your vegetable garden on a Saturday afternoon, you will most likely want a safe storage space for all your gardening equipment. Keeping garden tools in the garage can take up space, and the smell of the compost and potting soil can smell a bit strong when it is mixed with odour of mechanics. In Orrell, cheap sheds are on offer…

Cloning the Tasmanian Tiger Part A The Tasmanian tiger or the Thylacine was a carnivorous marsupial that became extinct in 1933. According to the Australian Museum, the modern Thylacine made its appearance about 4 million years ago on the Australian mainland. However, it became extinct 2200 years ago on the mainland, possibly due to the competition with the dingo. (Evans.2015). The tiger’s main decline in Tasmania was largely due to the impact that humans had. The biggest cause of extinction…

A fresh backpack, a new outfit that makes just the right statement and a stack of notebooks waiting to be filled. Going back to school is equal parts nervous jitters and genuine excitement for what could be. At this time of year, it feels like anything is possible! So, use this time to make yourself the best gardener you can be. Espoma’s Back to Gardening School. 1. Build a Foundation for Success. For a garden to be great, superior soil is a must! Perform a quick soil test, study the…

animals nor plants can acquire it directly, but must rely on the assistance of prokaryotes, free-living and symbiotic bacteria, able to fix nitrogen and transform it into a useful element. Cyanobacteria in aquatic systems, azotobacter in the soil and Rhizobium bacteria that lives symbiotically at the roots of leguminous plants, all draw nitrogen from the atmosphere and transform it into ammonia, (NH3), or nitrate, (NO3), important nutrients for plant growth (Bear et al, 2013). Plants…

The term “evolution” is a theory to explain how earth becomes full of life from simple bacteria. Set by Darwin, it is a common concept accepted by the public. He used the finches on Galápagos Islands to explain an important concept for evolution, nature selection. He found that on Galápagos Islands, finches have many different types of beaks. Some are easy to crush seeds, some are easy to catch warms in the trunks, and others have their ways to use. But different types of beaks can only found on…

Algae, a form of biomass, help lakes, but they do need the right environment with the correct pH and different light conditions in order to aid the lake’s health. Algae use sunlight to make food for themselves and give themselves energy through the process known as photosynthesis by using chlorophyll. They also absorbs carbon dioxide, turning it into energy, which would take place more in the nighttime when it’s dark. In this longer-term experiment, I will be evaluating the sun or lack of sun’s…

The article “ When Did Photosynthesis Emerge on Earth?” was written by the principal investigator of the Ames Research Center team of the NASA Astrobiology Institute, David Des Marais. His experience has led him to publish more than 160 technical articles and chapters on many research topics such as the biogeochemical carbon cycle and the early evolution of the Earth and its biosphere. In this particular article, Des Marais establishes that life dates back to 3800 years ago and that not only…

C: In the early to mid-Silurian period, approximately 420 million years ago, this area was covered by a shallow tropical sea jam-packed with life in the form of plant-like animals, shellfish, living corals and Molluscs. When the sea began to dry up, the minerals dissolved in it became more and more concentrated. Magnesium in the water was absorbed into the limestone, which then became a harder, slightly different…

older lesions. The fungus causes infected leaves to turn yellow and drop from the plants. The lifecycle of the septoria brown spot fungus begins when it overwinters in crop residue, infected seed, leaf and stem debris as minute brown fruiting bodies (pycnidia). The microscopic spores produced on living tissues or dead plants are released during wet weather. Wind and rainfall disperses the spores onto healthy plants, and infection begins. Favorable…

(875 words) Woolly Days ahead for the Hemlock Tree -Angela Cannon-Crothers I like bugs, ask anyone. I am awed by the mechanics of their life cycles, the biodiversity of the entire Order of Insecta, the magical beauty of so many of their kind. But there are a few that strike more than a few heebe-geebes -- some are downright frightening. Take the tiny hemlock wooly adelgid (ah-del-jid) for instance: a needle sucking scale insect of miniscule proportions that reproduces asexually (no male…
