What are the main contributing factors in climate change, and what should we do about it? Climate change is undeniably one of the biggest problems which the world at large is currently having to deal with. There are many factors that are causing climate change but more importantly, there are numerous ways to combat it. One of countless examples is environmental damage. Through this issue, mega-cities like Delhi which is the capital city of economically developing India suffer constantly with problems

Results Overview We created a theoretical food web for Carlingford lough based on binary links, using species records consisting of 154 species, 674 links, a linkage density of 4.48 and a connectance of 0.0248 (Figure 2). The fundamental food web properties of Carlingford fell within 95% confidence intervals of webs of similar species richness (S) (n=12, between 126-170 nodes – Appendix 2), based on food webs listed in the food web catalogue by Riede et al. (2009). Figure 2. Carlingford lough fundamental

Ashley Goosic The Burgess Shale The Burgess Shale, located in Yoho National Park, British Columbia, was discovered by Charles D. Walcott in 1909. Walcott spent 18 years collecting and classifying the fossils located at this site. The Shale was formed about 530 million years ago, in the Cambrian Period. Most Cambrian rocks contain fossils of trilobite shells, cap-shaped or flattened shells, and brachiopods (Whittington, 1985). When Walcott went looking for North American Cambrian fossils in

Facing the Face of Death: Perseus Well over a thousand years ago, people in Greece believed in Polytheism. That is the belief in many gods. This is a paper to tell you about the story of one of the many gods, Perseus. Although Perseus wasn’t a full god, he was a semi-god and his story is still very important in Greek Mythology. There was once a king, his name was Acrisius and he had a beautiful daughter. His daughter’s name was Danae (GreekMythology.com). Now, Danae’s father Acrisius did

The shell of Limulus polyphemus frequently serves as substrate for a large number of epibionts, such as barnacles, mussels, oysters, polychaetes, slipper limpets, algae and other encrusting invertebrates ( Botton, 2009; Botton et al. 2015). The term epibiosis is used to describe a non-symbiotic, facultative association between the substrate organism and sessile animals (epizoans) or epiphytic algae (Botton, 2009). Using horseshoe crabs as a substrate may be advantageous for the epibionts in that

Running head: SNOWY PLOVERS: AN EXAMPLE OF HABITAT DESTRUCTION Snowy Plovers: An Example of Habitat Destruction and Ecological Reservation Attempts Matthew B Means San Jose State University Abstract The Charadrius nivosus, more commonly known as the Snowy Plover is a small bird that resides typically in sandy coastal beaches or by soft sanded areas by water. This species has over time had its population decimated largely due to habitat destruction. An unfortunate

An integrated study of the Mpenjati estuary-beach system. (Biological component) Abstract A study was carried out to find the abundances of animal organisms between both sides of the Mpenjati estuary. Zooplankton, Macro fauna, Meiofauna and Fish was sampled .Each of the species that reside in the estuary contribute to the diversity of the area and are essentially driving forces, ensuring optimal functioning of the ecosystem. The purpose of sampling such ecosystems is to find out how the interactions

NON – TECHNICAL SUMMARY The Environmental Impact Assessment is an ongoing process in terms of environmental and social considerations that places in a high priority the conservation and the enhancement of the natural environment. EIA is defined as the study of the effect prediction of a proposed projct on the environment. In addion, it may be described as a tool which helps to make an important decision comparing many alternative plans for a project and seeks to find the best solution combining all

Intense grazing by herbivores can drastically affect the amount of seaweed present. Having secondary metabolites can be used as a defence mechanism. Many different genres of algae were studied, having many different types of chemical compounds found on many different parts of the world. Most studies harvested and purified samples then exposed these samples to different herbivores. The herbivores varied in size from large fish to smaller organisms such as amphipods. Aspects such as survivorship, behaviour
