Biodiversity

Rudraksh Kapil Topic Area: Biodiversity Loss of biodiversity: what are the causes and what can we do? Biodiversity is the variety of all forms of life on Earth - plants, animals and microorganisms. Biodiversity refers to: Species; Variations within species; and interdependence of species. It is interesting to note that only about 1.2 million worldwide species have been identified and catalogued out of a towering total of about 8.7 million, as of August 2011[1]. A range of factors and…

2.3 Conservation 2.3.1 Drivers of biodiversity loss Biodiversity is subjected to numerous forces that threaten the loss of species and the depaupering of natural resources (Brand et al., 2008). Biodiversity loss drivers (mechanisms that influence the extinction of a species) are generally encompassed in (but are not limited to): environmental stress, large environmental disturbances, extreme environmental conditions, severe limitation of resources, the introduction of non-native species, or…

Why is biodiversity important to an ecosystem? Why is it so important that we have different species of animals living together? It is extremely important for different species to be living together, because they all rely on one another for survival. Including us humans, we rely on other species to survive. We don’t just rely on other species for survival, but evolution has driven us to evolve to adapt and live longer. In an ecosystem, there are habitats. In a habitat, there are populations…

Consequences of biodiversity loss Biodiversity is a phenomenon that all life on earth depends on. It is the link between all life on earth. In other words the web of life. There is a perfect interdependent system in place that allows every organism on earth what it needs needed to survive and the relationship between all is beneficial to all others, except in most cases humans. We have more of a symbiotic relationship with the earth and everything else on it where we could be seen as kind of…

1. What is the Biodiversity Intactness Index (BII)? (p. 289) a. The Biodiversity Intactness Index (BII) is the average abundance of originally present species across a broad range of species, relative to abundance in an undisturbed habitat. 2. What four pressure variables were investigated? (p. 290) a. The four pressure variables that this paper focused on were land use, land-use intensity, human population density, and proximity to the nearest road. 3. The “average local abundance of…

Biodiversity is the measurement of how abundant variety of species is the population in an ecosystem. Habitats are greatly amplified by how many different species populate the area as the interconnectivity of food chains influences how well an ecosystem works. Not only does biodiversity effect specific ecosystems, it provides for humans as the value of global ecosystem services is estimated at $16-$64 trillion [1] meaning that reduction of biodiversity will result in major financial losses. A…

Five Research Articles on Biodiversity Succession in Ecology: Summaries Article 1: “Effects of nitrogen deposition on soil and vegetation in primary succession stages in inland drift sands” What kind of system was being considered? -They studied the Inland drift sands in the areas of the Netherlands. They specifically looked and studied at the Drethe, Veluwe, Utrecht, Brabant, and along Meuse. They wanted to consider how plants grow and develop during succession. The author’s hypothesis: -The…

Fota Wildlife Park John Lawlor T00172305 Why is conservation important: Conservation is the protection and maintenance of populations of plants and animals. It requires the protection of ecosystems and the biodiversity in these ecosystems. 'Biological diversity – or biodiversity – is the term given to the variety of life on Earth. It is the variety within and between all species of plants, animals and micro-organisms and the ecosystems within which they live and interact.'(Wwf.org.au, n.d.)…

Species are dying, which in turn causes the loss of biodiversity. In order to have a sustainable environment, there needs to be an increase in biodiversity. Biodiversity refers to the variety and variability of life on Earth. The number of species of plants and animals are both part of the biological diversity of the Polynesia-Micronesia hotspot. The loss of biodiversity in this hotspot damages crucial services provided by nature. A biodiversity hotspot is a region with a significant amount of…

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 measured area. we recognize three types of biodiversity 1.genetic diversity…
