MMidterm 1 - Review

Facts - Something known to be true. Principals - Actionable things that cause something to happen - Give more insight than facts - Ex. Predators like lake trout link different parts of the lake by moving between them to forage.

The study of how organisms interacts with one another and their physical environment. - How species interact - What species eat - How are the seeds distributed - How harsh winds in the winter or disease affect the species

The study of the processes influencing the distribution and abundance of organisms. - Where are species found and why - Where are species not found and why - How many of a species are found and why - How and why does a number of individuals in a species change over time and why

A property that is not present in the levels component parts but emerge from these parts interactions and relationships. - Arise from the interactions and relationships among the components at each level of biological organization

A community level change over long periods of time - You could not understand succession by studying individual populations - You must study the community

The assemblage of a host species living in or around it, which together form a discrete ecological unit through symbiosis - Ex. Bear + microbiome = holobiont

A collection of inter-related populations - Not just population, not just community, but in-between

True - Dynamic steady state - Dynamic stability

• Growth • Decline • Dynamic Equilibrium

• Increased fishing of cod caused an abundance of pelagic fish. • Increased pelagic fish caused in increase of seals due to the abundant food source. • Increased seals further depleted cod.

Science is a process for understanding the world and can be thought as - a collection of knowledge - a process for the collection of knowledge

Natural history and taxonomy

The scientific study of animals or plants, especially as concerned with observation rather than experiment, and presented in popular rather than academic form.

The branch of science concerned with the classification of organisms - Morphological characters - Behavioural characters - Ecological characters - Geographic characters

The act of noting or perceiving a phenomenon or event using the senses or scientific instruments. - Often formulated as patterns sometimes termed as phenomenon

A system of casual interaction parts and processes that produce one or more effects or phenomena. - Let us explain why - Let us predict

• Why is it found where it is found • Why is not found where it is not found? • Looking at climate • Looking at soil type • Looking at other plants or insects in the area • human impact on the environment • movement of seeds • water distribution • permafrost/seasonal weather

The range of environmental conditions and resource use that allows a species to persist and reproduce - The range of abiotic and biotic conditions that an organism can tolerate.

Consume the blood of the host.

True

In the most extreme environments where essential biological molecules cannot exist. - Most extreme temps or pH

Organisms that are able to live in extreme conditions

The compromises organisms make in allocating limited resources to different aspect of their biology, behavior or physiology, influencing their fitness and adaptation to specific environment condition. - Giving up one thing in return for another - A balancing of factors all of which are not attainable at the same time.

Refers to a relatively large area of the Earth’s surface with distinct environmental conditions. Dependant on: - Topography - Soil - Geological factors - Disturbance events - Human influences
