RELATIONSHIP BETWEEN SPECIES DIVERSITY AND SIZE Effect of Surface Area on the number of species in biodiversity. Yes, there is a relationship between species diversity and size, the smaller the habitat the less diversity of species there will be. Species diversity is the variety of organisms that make up a community It has two components: • SPECIES RICHNESS: is the total number of different species in the area • RELATIVE ABANDANCE: is the proportion each species represents in that certain…

In the literature, different equations are used to calculate the energy requirement for birds (Emmans, 1974, Peguri and Coon, 1988, NRC, 1994, Sakomura et al., 1993, 2006), the factorial model has been the basis for the elaboration from these models, estimating the requirements consider the differences in weights, body composition, potential for growth and production of the animals, as well as the environment. The factorial method is based on the principle that the requirement in energy or…

to have developed over 450 million years ago with the evolution of land plants. It has also been suggested that there was a co-evolution between plants and microbes as their morphology and metabolism is intrinsically linked (G. Berg et al 2015). Humans of course benefit from the plants-fungal interactions, as plants are essential for oxygen production and their growth and development is benefited by microbes. The extent of those interactions and their benefits, and…

Piers Stephens (2009) states that Ecological sustainability implies the satisfaction of three conditions in human interactions with nature: a). Rates of use of renewable resources must not exceed their rates of regeneration; b). Rates of use of non-renewable resources must not exceed the rate at which renewable substitutes can be developed; and c). Rates of pollution…

Ted Talk Paper The two Ted Talks I chose ended up being very intriguing due to the fact that one of them was given by a scientist and the other by an artist. The first Ted Talk I watched was called “How to Grow Fresh Air” by Kamal Meattle. Meattle explained the importance of fresh air in Delhi, a city plaqued by poor air quality, and provided a solution utilizing three types of green plants. The second Ted Talk I watched was called “Street art with a message of hope and peace” by eL Seed. eL…

Splish, Splash! You hear the water splashing as you go by the Everglades. You see various animals crocs, snakes and all. Yes all this wild life is pretty fascinating isn't it, but has anyone payed any mind to the Drastically rising numbers of pythons that have been coming from other areas other than Florida. A lot of people aren't seeing them as a threat because it doesn't concern them to know about it. There are many ways some people are trying to deal with this problem but will it be…

The Rubus ellipticus Sm., commonly known as the Yellow Himalayan Raspberry, have become a nuisance to wetlands in Hawai‘i. Just a small population can rapidly grow, damaging or eliminating all other plants in its path; most which is native plants (tree, shrub, fern, and herbs). Studies have shown that within a long period of time, four herbicides can greatly influence the decrease of the raspberry. The Yellow Himalayan Raspberry originated in Southern Asia. This plant is a shrub with edible…

Environmentalist ideas have been present in literature and art for centuries, with landscapes scenes and the appreciation of nature depicted in the brushstrokes of Patenir or the poems of Whitman. It was not until the late 1940s, however, that the modern environmental movement began to take shape with the passing of the Federal Water Pollution Control Act, the first federal regulation legislation passed to monitor water quality. Since then, environmentalism has blossomed from that single piece…

I was conceived at the bottom of Grand Canyon. At four months old I was on my first river trip. The Colorado River banks were my first playground, and as someone who wants to preserve the wild landscape that I call home, I am looking to the future to figure out what I can do to ensure its protection as environmental changes continue to occur. The rivers of the west are my sanctuary, whether it be the Green, the San Juan, or the mighty Colorado, every river trip I have ever been on has been one…
