These different mesh sizes would hopefully catch a range of plankton from Mesozooplankton to Picoplankton. The water samples would be taken back to the lab where we would attempt to identify the individuals to species level. To do this we would use different microscopes, depending on the size of organism and identification guides. We had the option to either use a binocular microscope or a monocular microscope. Discussion Nutrients is vital for the survival and formation of a food web, it is essential for the growth of plankton. In the marine environment Nitrogen is usually the growth-limiting nutrient.

Graduated cylinder Hot Plate 3 Large beaker (1 for warm water, 1 for cool water, 1 room temp) 3 thermometers Procedure: 1) Day one: Before beginning the actual lab-Listen for teacher instructions and familiarize yourself with the LabQuest datalogger and its functions using the quick start guide. We will devote this day to learning how to use the datalogger so that tomorrow you can quickly set up your lab and begin data collection. 2) Get the Probe ready (Note: this may have already been done for you-if you're not sure ask me.) A. Remove the blue protective cap from the probe (if present)

It can also provide information on the identity unit in the population. Temporary emigrations, where animals may not be available at every sampling occasion, also adversely affect such analyses. Identifying features are vary between species. This allows us to identify individual species. According to Weinrich (2001): "If observers noted any distinctive dolphins, an attempt was made to photoidentifity them. Two classes of distinctive individuals were noted. Some animals were immediately recignizable through highly prominent marks, including partly missing dorsal fin or large amounts of white pigment on the dorsal fin or flanks..

The organic compounds and carbon isotopes compounds were confirmed by Sephton et al. using high-resolution gas chromatography - mass spectrometry. The organic soil matter was specifically furan structures which are produced by the dehydration of cellulose and, when found in fossilized organic matter, which are usually presumed to be the remains of dehydrated polysaccharides. This DNA implied that the initial soil conditions were very good for burying and preserving eroded organic soil matter in the marine ecosystem. To further support the hypothesis of the end-Permian Soil Crisis, Sephton et al. needed evidence of excessive soil erosion from other land masses that had been a part of the single land mass of Pangaea.

Brightly coloured lichens form distinct bands on the high shore, seaweeds are present in abundance, and where sediment occupies rockpools flowering plants dominate. This assignment will look at the comparison of marine organisms on two wave cut platforms; shale and limestone. There are three simple aims for the fieldwork at Doolin, all of which are achievable and important to our findings: 1. To determine if there is any relationship between organisms and bedrock type. 2. To establish if there is any correlation between bio-diversity and distance from shoreline.

Introduction Back pain is a common complaint that is frequently seen and treated in clinical practice affecting one in five of the population. If the condition remains for over three months it is referred to as being 'chronic'. Research has discovered that injuries in peripheral joints have resulted in propriceptive deficits (Willems 2002, Liu-Ambrose 2003) and this study aims to investigate whether this is also true in patients with chronic low back pain (CLBP) as previous evidence suggests there is.

Abundance, Distribution and Species Diversity of Invertebrates Collected By Commercial Trawler From Near Shore Coastal Areas of Karachi, Pakistan (Northern Arabian Sea).
KEY WORDS: ABUNDANCE, DISTRIBUTION, DIVERSITY INDEX, H', COMMERCIAL TRAWLER, COASTAL AREAS OF KARACHI, (NORTHERN ARABIAN SEA). INTRODUCTION Commercial trawlers along the cost of Karachi are conducting a lot of bottom trawling. One of the supports of the regional economy and fulfill the needs of protein source of the country. Little information is available in the literature on the bottom dwelling macro-faunas of the coast of Pakistan. There is thus a grate gap in our knowledge about our own marine fauna.

Green zones have been instigated by governments across the world in order to improve and aid the marine ecosystem, the habitats and the animals that live there. There are many success stories from the implementation of green zones including the Cabo Pulmo reef in Mexico. Research has recorded that the fish biomass has increased by 460%, the average biomass was more than five times greater than the average biomass in the Gulf of California, and that manta rays, humpback whales, whale sharks and sea turtle populations recovered in the area (Cabo Pulmo: A Marine Protected Area enables biodiversity and the local economy to rebound, 2014).

In the ensuing process of reclamation of the land or the ecosystem to suit the specifications of man, the environment suffers a great deal. The environment, whether very harsh or conducive, is home to other animals. Encroaching on these lands and making them habitable for humans inconveniences the rest of the animals a great deal. The inconvenience may result in the animals reacting in diverse ways; these could be as diverse as some of the animals dying in mass thereby resulting in extinction of species (Kevin, 1998).
