  • What Are Algal Blooms and Why Do They Matter?

    When algae die, they are decomposed by bacteria, which can remove oxygen from the water, occasionally killing fish. Algal blooms can also make water unfit for even recreational use. These tiny organisms can therefore have a huge impact on health, wildlife and economies that depend on fishing and tourism.

    Organic Matter Preservation in the Sediment of an

    Sustainable management of acidic mining lakes requires knowledge on the origin and reactivity of its sedimentary organic matter. We identified different pools of organic matter (OM) in the Fe-rich sediment (up to 35 wt %) of an acidic (pH 2.8) mining lake using δ 13 C-signals, C/N ratios, and the markers alkanes, lignin-derived phenols, and benzenepolycarboxylic acids (BPCA).

    Lanthanides and Algae

    10/4/2018This chapter discusses the ecological and physiological impacts of lanthanides on algae as primary producers in aquatic environments. Although lanthanides are nonessential elements for living organisms, their bioaccumulation is a common phenomenon. Here, we critically review the ecological effects of increasing levels of lanthanides directly reaching water systems through mining

    By feeding the algae eaters that control algae growth, they become handout feeders that soon neglect their important role of eating algae, which in turn can overgrow coral. Major conservation organisations, including UNEP, DAN, WWF and Environmental Defence, encourage passive interaction with marine life and avoiding feeding and petting, which may lead to accidental injury.

    Because algae serve as a food source, larvae nursery, and invertebrate habitat, mining and bleaching harm not only coralline algae but also its co-dependents.
