What does the field approach in ecology involve?
Press to flip
The field approach in ecology involves making observations in natural settings, such as observing the longer-chital association in nature.
What important lesson did Miss X's Village Incident illustrate?
Miss X's Village Incident highlighted the indirect effects of chemicals, such as insecticides, on the ecosystem, leading to unintended consequences like the death of bird species.
Describe the theoretical approach to studying ecology.
The theoretical approach uses equations and models to understand interactions, such as predator-prey dynamics.
Why are high levels of PCBs in the breast milk of Inuit women concerning?
High levels of PCBs in the breast milk of Inuit women are concerning because it indicates that harmful chemicals can travel and accumulate in isolated regions, posing ecological and human health risks.
What is the origin of the term 'Ecology'?
The term 'Ecology' originates from the Greek words 'Oikos' meaning home and 'Logos' meaning study.
What are biotic factors in ecology, and provide examples.
Biotic factors are biological factors affecting organisms, including food availability, presence of predators, parasites, and diseases.
Explain the term 'Human Ecology.'
Human Ecology is the study of human populations, their dynamics, and their interactions with the environment.
What is meant by 'Distribution and Abundance' in ecology?
It refers to the factors that determine where organisms live and how many of them are present in various environments.
Discuss the impact of climate change as covered in the course.
Climate change is altering ecosystems, species distributions, and biodiversity patterns, and is a topic discussed under the module 'Ecology of Change.'
What are the main study areas in ecology?
Habitats, biodiversity, population interactions, community interactions, and the effects of changes such as human activities.
How does temperature variation in mountain zones affect organism distribution?
Temperature variation in mountain zones results in different organisms being found at different levels due to the varying environmental conditions.
List the physical factors in ecology.
Temperature, rainfall, humidity, wind speed, soil depth, sunlight, and in marine contexts: salinity, sediment load, and water speed.
What are intraspecific and interspecific interactions?
Intraspecific interactions are interactions within a species, while interspecific interactions are interactions between different species.
Name the modules covered in this ecology course.
Introduction, Historical Overview, Ecology and Evolution; Ecological Structure; Interactions; Energetics; Population Ecology; Community Ecology; Distribution and Abundance; Management of Threatened Species; Human Ecology; Ecology of Change; Applied Ecology; Revision.
What is an example of a study using the laboratory approach in ecology?
An example would be formulating and testing hypotheses through experiments like studying factors that limit algae population in a pond.
