Biodiversity is the measure of the variety of different numbers of organism can be affected by many environmental, as well as human factors. This specific study measured how different depths affect the biodiversity in the Indian River Lagoon.
In the month of October, specifically, the knee depth had an H’ value of 0.35, the waist depth had an H’ value of 0.65 and the chest depth had an H’ value of 0.67. The knee depth had a greater number of different species of fish, as well as a higher number of fish caught in general. But, the chest deep had a higher H’ meaning that the species richness is higher in that area than the others. The species evenness for each depth followed the same trend in that the knee depth had the lowest value, while the chest depth had the highest value. Comparatively, in the month of November the trend seemed to be the same as in October except the H’ values for each depth increased but the number of species caught decreased across the board. The only difference is that the total number of fish caught decreased for the knee and chest depth but increased for the waist depth. The species evenness for the chest depth was almost equal to 1 because the theoretical richness yield was close to the actual species richness (H’).
When concerning a study on seagrass diversity, it was reasoned that biodiversity increased in the Indian River Lagoon the more farther out one got from the shore because of the difference in species number as one gets to the submerged plants category (Dawes 59). The hypothesis is further maintained from this particular fish study, that in the Indian River Lagoon that the This could be because the deeper you get into the lagoon the less human contact available which in turn allo...

...ons, then that will affect other species either negatively or positively. As another point, if multiple species decline, then the ecosystem can start to decay and break down, which further can disrupt the natural flow of life cycles (Maclaurin 1.1). The results can be used to further the growth of these species in this ecosystem as well as a gateway study into other studies.
Future investigates can include the study of the effect of sea grass on these fish species and truly evaluate whether or not the increased biodiversity in the deeper waters is attributed to these different submerged seagrass faunas. If this point is proven to be true, then the conservation and promotion of sea grass maintenance and growth in the Indian River Lagoon can be a new cause for this local environment to invest in to ensure well-kept economic growth (Biodiversity conservation: a guide).

- Discuss the different uses that biodiversity has for society, and how this may justify biodiversity conservation. Incorporate relevant case studies into your discussion. Word count: 1,126 Due date: 17/11/2014 Biodiversity and Society Biodiversity has remained an integral factor for enabling the existence of life. The English Oxford Dictionary, (2014) defines biodiversity as the: “diversity of plant and animal life, especially as represented by the number of extant species.” Humankind rests dependent on the rich plant and animal species that exist today in our world whereby these species lay at the heart of sustaining ecosystems that are agricultural and natural (Myers 1994, Raven and Joh...

- INTRODUCTION The 14th of December 2013(Saturday) was the day when this fieldtrip was organised .it was a pleasant day, our whole class of grade 10 evm students (25 students) got ready and we head out for wazirabad Delhi. We had decided to go to three places and collect water samples so that we could conduct different tests on samples such as: 1. Ph. value test 2. BOD level 3. Coliform level To see how polluted river Yamuna gets ,as it passes different destinations in the nation capital region, but ended up going to only two places as we were running short of time.one of two place where we visited had water going downstream and at the other place water was pretty still....

- "If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us." -- David Suzuki Imagine this: bulldozers growl and grind through a local field, while the whine of chainsaws echoes from a nearby grove of trees. The trees crash to the ground, only to be cut up for firewood or sent to a sawmill, and the remaining ground is cleared of stumps and plowed. The tall grasses and brush in the field are demolished, leaving behind churned-up soil.... [tags: Loss of Biodiversity]

- Biodiversity is commonly described as the variety and diversity of life on Earth. “The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth” (Shah, A. 2012). In fact, Earth is made of complex ecosystems’ interacting with each other’s, giving life to any and every species, impacting on climate, human and animals’ lives and so much more....

- Venice – a lagoon city. There is hardly any city characterised by such opposing attributes as Venice. Many may consider Venice to be the city of love and a senic gem on the water, novels and films usually paint a different picture. The city frequently appears morbid, mysterious and dark. During winter and autumn fog occupies the whole city. Venice is used by many authors as a backdrop to create an environment of suspense and death. Venice is an allegory of death, decay and rot. The city itself represents the literary synonym of the deterioration of the architectural wonder.... [tags: geography, death in venice]

- Loss and Healing in The River Warren Each of us, in time, will experience a heart-stopping reality - the death or loss of someone or something we love. Maybe it will be of a family member or just a pet we dearly cherished, but the feelings we have are all too real and all too painful. This loss is probably by far the greatest and most severe emotional trauma we can encounter, and the sense of loss and grief that follows is a healthy, natural, and important part of healing ("Death")....

The number of livestock animals produced in the United States has grown modestly in the past two decades, but the number of farms raising them has slunk dramatically because large producer now dominate the market. The large increase in industry farming has led to large quantities of manure. B.

- Biodiversity Imagine this: you step outside and feel the barren, rough, red Earth beneath your feet. There’s not a single plant in sight—no rustling of the leaves, no mighty towering trees to block the severe winds, and the scorching heat of the sun searing upon your face because there’s no shade. And when you take a whiff of air, you feel nothing filling up the space inside your lungs, liberating your body’s activities. What’s wrong with this picture. It’s not possible, of course. Even though plants aren’t the building blocks of life, they’re pretty close and without them, most of life wouldn’t exist—YOU wouldn’t exist.... [tags: plants extinction ecosystem]

- Biodiversity INTRODUCTION Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well....
