A novel method to measure algal blooms

Posted · Add Comment

Algal blooms can cause significant environmental damage producing toxic effects on people, freshwater and marine organisms. Understanding and quantifying algal blooms often involves expensive or laborious scientific equipment. However, researchers at the USA Environmental Protection Agency recently adopted a novel method to study algae in a river system in the United States. The methods involves […]

Zooxanthellae Photosynthesis

What do pH and photosynthesis have in common?

Posted · Add Comment

Photosynthesis is the synthesis of nutrients from carbon dioxide (CO2) and water driven by sunlight. pH is a measure of hydrogen ion concentration in a solution. It might not seem so obvious at first, but there are actually certain circumstances where a change in pH can tell you something important about photosynthesis. Take Figure 1 […]

Acidification CO2 Climate Change

The reality of ocean acidification experiments

Posted · Add Comment

Increasing atmospheric carbon dioxide (CO2) is not only altering climate, but it is making the oceans more acidic. This process, known as ocean acidification, is predicted to lead to massive rates of extinctions particularly of corals. Given the huge biological, ecological and economic impact of ocean acidification, a large amount of research effort has been […]

– a look at the ramifications of species extinction for biogeochemistry and ecosystem functioning. Around Sydney there is a tiny species that every developer hates: the Cumberland Plain Land Snail. This species has stopped, delayed or significantly changed many developments across the Sydney basin, and is even said to be the snail that rules Sydney. Recently we […]

Many tropical marine species are starting to appear in temperate waters. Around Sydney, several tropical fishes, such as surgeonfish, have been observed. Corals have also been found to be overtaking algal forests off the coast of New South Wales. In New Zealand, tropical fishes have been observed in marine waters where they have never been seen […]
