Study Notes

Biological Resource Management

The primary purpose is to ensure sustainable use and conservation of biological resources.
Conservation aspect focuses on protecting biodiversity and maintaining ecosystem health.
Key importance lies in providing essential resources for human survival, ecological balance, and economic sustainability.

Resources for Plants and Animals

Water, sunlight, and soil nutrients are key resources; air is included for plants.
Not considered key resources vary by context, such as urban development impacts or waste.
For animals, food, water, and habitat are essential; pollution can be detrimental.

Sustainable Resource Use

The primary goal is to use resources in a way that meets current needs without compromising future generations.
Sustainable harvesting techniques include selective logging and regulated fishing; overharvesting is unsustainable.
Purpose of sustainable harvesting includes maintaining ecosystem balance and ensuring resource renewal.

Ecosystem Health and Management Principles

'Ecosystem health' pertains to the vitality and functioning of ecosystems in resource use context.
The ecocentric paradigm emphasizes intrinsic value of nature in biological resource management.
Adaptive management allows for iterative learning and adjustments in management strategies based on environmental feedback.

Principles and Relationships in Ecosystems

The precautionary principle advocates for preventive action in resource management to mitigate harm.
Mutualistic relationships benefit both organisms; not all interactions are mutualistic.
Healthy ecosystems display biodiversity, resilience, and efficient resource cycles.

Ecosystem Dynamics

A species that maintains ecological structure is termed a keystone species.
Food chains show linear energy flow; food webs illustrate complex interconnections among organisms.
Autotrophs are primary producers, capable of photosynthesis or chemosynthesis.

Roles of Organisms in Ecosystems

Decomposers break down organic matter, recycling nutrients; detritivores consume detritus.
Primary consumers eat producers; secondary consumers eat primary consumers.
Chemoautotrophs play a crucial role in nutrient cycling, particularly in extreme environments.

Ecosystem Factors and Functions

Factors affecting ecosystem condition can include climate change, habitat destruction, and pollution.
Understanding these dynamics is essential for effective biological resource management and conservation efforts.
