Plant Water Regulation
Plants need to regulate water in order to stay upright and structurally stable. Find out the different evolutionary adaptations of plants in terms of structure (e.g. stomata) and physiological mechanisms (e.g. root pressure, capillarity, transpiration pull, curving of leaves, etc.) that enabled them to maintain the appropriate water level...
Ecosystem Succession
If the balance of nature is left untouched, landscapes can change dramatically over time. A previous ecosystem is superseded by the arrival of a newer ecosystem. This is known as ecosystem succession. Learn more about it here...
Mātauranga Māori and Science
Mātauranga Māori is the living knowledge system of the indigenous people of New Zealand, including the relationships that Māori have with the environment. This lesson uses the Toheroa Abundance Project as an example of how Mātauranga Māori is influencing ecological outcomes. The lesson is designed to showcase the value of indigenous cultural perspectives and knowledge of the world around us. ..
Population Regulation in an Ecosystem
With regard to the population size of a species and what factors may affect them, two factors have been defined. They are the density-dependent factors and the density-independent factors. Find out the differences between the two in this tutorial. Know how these factors affect populations in an ecosystem...
Physiological Homeostasis
Homeostasis is essential to maintain conditions within the tolerable limits. Otherwise, the body will fail to function properly. The body does this through feedback control mechanisms, e.g. blood sugar level regulation and temperature regulation. Read this tutorial to know more about the principles of negative feedback control employed by the body to sustain homeostasis...
Ecology & Biodiversity: New Zealand Flora & Fauna
New Zealand is known for its unique biodiversity, caused by its remarkable geography and geologic history. Breaking away from the supercontinent Gondwana about 80 million years ago, it has developed a distinct flora and fauna as a result of long geological isolation. Thus, many fascinating plants and animals are found nowhere else but in New..
