Copy-number variation (CNV)

refers to the phenomenon where the number of copies of a particular gene or genomic region varies from one individual to another in a population. These variations can result from duplications or deletions of segments of DNA and may play a significant role in genetic diversity, disease susceptibility, and evolutionary processes.

New cards
What is biodiversity?
The product of evolution shaped and sustained by ecological interactions among organisms and their environment.
3
New cards
What does the Cambrian explosion hypothesis suggest?
Rapid evolution during the Cambrian period led to the differences we see today.
4
New cards
What is adaptive radiation?
A period of unusually rapid evolutionary diversification in which natural selection accelerates the rates of both speciation and adaptation.
5
New cards
What are the criteria for adaptive radiation?
Common ancestry, trait-environment correlation, trait utility, rapid diversification.
6
New cards
What defines a population in ecology?
A group of individuals of the same species that live, interact, and interbreed in a particular area at the same time.
7
New cards
What are the three key features of populations?
Size, range, and density.
8
New cards
What is a life table?
A table that presents information about how many individuals of a cohort are alive at different points in time.
9
New cards
What is survivorship in ecology?
The proportion of individuals from the initial cohort that survive to each successive stage of the life cycle.
10
New cards
What defines R-strategists?
Species that produce large numbers of offspring but provide few resources for their support.
11
New cards
What is the carrying capacity (K) in population ecology?
The maximum number of individuals a habitat can support.
12
New cards
What is logistic growth?
A pattern of population growth where growth potential decreases as the population size approaches K.
13
New cards
What is mutualism?
An interaction between species that benefits both parties.
14
New cards
Define the term 'niche' in ecology.
The combination of a species' physical habitat and its ecological role in that habitat.
15
New cards
What is primary succession?
The process of ecological recovery starting from a state with no life present.
16
New cards
What describes the 10% Rule in ecology?
Only about 10% of the energy in biomass at one trophic level is incorporated into the biomass of the next level.
17
New cards
What is coevolution?
The reciprocal adaptations between closely interacting species.
18
New cards
What is the impact of invasive species on ecosystems?
They can expand dramatically when introduced to new areas, often with devastating consequences for native species.
19
New cards
What is the Red Queen hypothesis?
The idea that organisms must constantly evolve to keep up with their environment and competitors.
20
New cards

What is the latitudinal diversity gradient?

The pattern that biodiversity increases from the poles to the tropics, with higher species richness in warmer, tropical regions.
