Constructed wetland treatment systems have been used for decades to treat wastewater, but their application to treat oil sands process-affected waters is relatively new. To explore this potential, a surface flow mesocosm design and experimental methods are outlined. This approach aims to enhance our understanding of key design parameters and improve treatment efficacy.

An integrated suite of imaging techniques has been applied to determine polyp morphology and tissue structure in the Caribbean corals Montastraeaannularis and M. faveolata. Fluorescence, serial block face, and two-photon confocal laser scanning microscopy have identified lobate structure, polyp walls, and estimated chromatophore and zooxanthellae densities and distributions.

We present methods to evaluate how predation risk can alter the chemical quality of herbivore prey by inducing dietary changes to meet demands of heightened stress, and how the decomposition of carcasses from these stressed herbivores slows subsequent plant litter decomposition by soil microbes.

What is an Ecosystem?

Overview An ecosystem is the interaction between all abiotic and biotic factors in an environment and can be classified as terrestrial or aquatic. Terrestrial ecosystems are categorized based on the climate, including annual temperature, rainfall, and seasonality. Aquatic ecosystems are separated further into freshwater and marine, and then by depth, which influences water temperature and the amount of sunlight that penetrates the water. Terrestrial Ecosystems Terrestrial ecosystems are...
FAQs
Researchers can regulate temperature, light, nutrients, carbon dioxide, and water flow individually or in combination. They then observe how these conditions affect coral health, bleaching, calcification, biodiversity, and interactions among corals, algae, microbes, and other organisms. This controlled manipulation helps connect a particular environmental change with ecological responses that would be difficult to isolate in a natural reef.
Laboratory control allows researchers to change selected environmental conditions while keeping other factors regulated. Including corals, algae, microbes, and other reef organisms preserves important biological interactions rather than reducing the study to a single species. This combination produces evidence that is more ecologically informative than a highly simplified experiment and more experimentally manageable than observing uncontrolled environmental change alone.
Changes in temperature, light, nutrients, carbon dioxide, and water flow can alter the conditions experienced by reef communities. Researchers examine resulting differences in coral health, bleaching, and calcification, while also tracking biodiversity and ecosystem interactions. Studying these responses together helps reveal how physical and chemical changes may influence biological processes across more than one component of the reef community.
A study begins by assembling seawater with reef-building corals, algae, microbes, and other selected organisms. Researchers regulate relevant physical and chemical conditions, such as temperature or carbon dioxide, and deliberately manipulate one or more variables. They then monitor community responses, including coral condition, bleaching, calcification, biodiversity, and interactions, comparing outcomes across the controlled experimental conditions.
The system typically contains seawater, reef-building corals, algae, microbes, and other organisms chosen to represent important reef components. Its conditions may include controlled temperature, light, nutrient levels, carbon dioxide, and water flow. Together, these biological materials and regulated factors create an experimental setting where researchers can test environmental changes while retaining several features of reef ecosystem complexity.
Researchers use reef mesocosms to investigate how coral communities may respond to climate change and other human pressures. The systems are especially useful when studies need both experimental control and realistic ecological interactions. Measurements of coral health, bleaching, calcification, biodiversity, and community responses can support comparisons among environmental conditions and improve predictions about future reef responses.
