acids from the algae stimulate a virus that causes the tumors. Scientists have been trying to understand the pathology of these tumors. The tumors were most commonly located on the turtle’s heads‚ eyes‚ and flippers. According to Celia Smith‚ UH Mānoa Marine Biology Professor‚ “Many hypotheses were offered to explain the tumors‚ but we kept coming back to the observation that urban reefs—those near dense populations—are the sites with greater numbers of sick turtles. We had no mechanism for this disease”

Declining Fish Stock One major problem we are facing as a country is the rapid decline in several different species of fish in the ocean. Some specialist have actually looked into this to determine the cause for the decline in fish in the ocean. One of the major causes is that some species of fish are being fished more than others. It is even stated that more fish than the species are being able to actually reproduce. This alone could eventually lead some of the species into extinction. This is

How the plantation affect biodiversity? The positive impacts to biodiversity of plantation Trees used in plantations may have more conservation value than existing vegetation such as pasture‚ also it may improve downstream water quality and provide habitat for aquatic biota. Moreover‚ it will sequester carbon and hence contribute to mitigating or reducing climate change. The plantation may lead to reduced pressure on the harvest of rainforests elsewhere. Most importantly‚ Biopact (2008) explained

1. What are rocky shores? They are big rocks that are exposed at low tide 2. How are organisms on a rocky shore distributed? By the horizontal zones that relate to the tolerance of the species to either exposure to air or under water. 3. What three types of bedrock are typically found in a rocky shore ecosystem? Rocky shores‚ sandy shores‚ and salt marsh 4. What are the different zones of the rocky shore? Upper = splash‚ middle = littoral‚ lower = sub littoral. 5. What plants are found in each

5.Explain how a Harmful Algal Bloom can impact an ecosystem. The toxins can be spread throughout various organisms as of humans and the food chain. If the consistent blooms it can block the light from reaching into the water and it can cause many organisms dead. 6.Create a chart or Graph showing the estimated economic impact of HABs on the United States over three years.

Factors leading to Biodiversity Loss: Biodiversity is affected by multiple drivers and pressures that modify its ability to provide ecosystem services to people. The interaction of multiple drivers‚ including demographic‚ economic‚ socio-political‚ scientific and technological ones‚ as discussed earlier‚ is known to increase pressures on biodiversity‚ leading to further decline‚ degradation and loss. However‚ the mechanisms associated with such loss require further research. The direct mechanisms

Biodiversity is disappearing at an unprecedented rate. Worse‚ the trend appears to be accelerating‚ in spite of international commitments to reduce‚ or even halt‚ the rate of loss by 2010. Good systems of science governance capable of using biodiversity sustainably and equitably will be essential if we are to reverse the trend. UNESCO helps governments and policy-makers make informed decisions about biodiversity conservation within international efforts like the Convention on Biological Diversity
