Study Notes

Grizzly Bear Populations and Hunting Impact

Hunting significantly influences grizzly bear populations in British Columbia, affecting their numbers and ecological dynamics.
Community ecology examines interactions between species and factors impacting biodiversity and productivity within environments.

Ecology Concepts

Ecosystem ecology studies the interactions of organisms, chemical, and physical processes, focusing on energy flow and nutrient cycling.
Landscape ecology analyzes how landscape patterns influence ecological processes, particularly the impact of human-altered landscapes on species movement.
Macroecology investigates large spatial processes that shape abundance, distribution, and diversity of organisms across regions and continents.
Global ecology encompasses processes on a global scale, with a strong focus on global climate change and its effects on ecosystems.

Definitions in Ecology

Ecology is the scientific study of interactions between organisms and their environment across various organizational levels: individuals, populations, communities, and ecosystems.
Population ecology focuses on factors that influence population structure and dynamics, including birth and mortality rates.

Branches of Ecology

Autoecology emphasizes individual-level interactions between organisms and their environments, often studying behavior and physiology.
Examples include understanding dietary habits of species, like caribou during different seasons.

Scientific Inquiry in Ecology

Scientific inquiry follows a systematic approach to asking and answering ecological questions, such as studying the effects of urbanization on bee diversity and abundance.
Example hypotheses can include the link between urban flower diversity and pollinator numbers.
Experiments often involve controlled environments to compare results across different ecological settings.

Importance of Scientific Effort

Scientific inquiry is time-consuming but essential for informed decisions in environmental management, policy-making, and economic strategy.
