What is boom and bust ecology?
Boom-and-Bust cycles occur when the population growth of one species is closely tied to a limiting factor that may be expended. The predator populations increase and decrease as the prey numbers change. Predation may be an important cause of density-dependent mortality for some prey.
What is boom and bust cycle in plant pathology?
The “boom-bust cycle” of resistance genes refers to the widespread use of a single resistance gene that protects multiple varieties of a grain from a disease (boom). When the disease overcomes this resistance gene many varieties simultaneously become susceptible (bust).
What is gene pyramiding in plants?
Gene pyramiding refers to the process of stacking multiple genes into a single genotype to combine desirable traits through recombinant DNA technology or conventional breeding. This approach has resulted in the so-called ‘second generation’ of GE plants.
Is there a boom after a recession?
There is no single definition of a boom, nor a committee of elite economists who agree when one has begun, as there is with recessions. Growth never took off after the mild recession that hit in 2001, and while the unemployment rate hit a half-century low after the last recession, it took a decade to get there.
When does the boom and bust cycle occur?
The boom is when the population grows exponentially rapidly, it is then followed by a bust, which is when the population falls back to a minimal level. Boom and bust cycles are like rollercoasters. The population grows only up, up, and up and eventually it reaches the bust cycle and it goes back down.
What are boom bust dynamics in biological invasions?
Boom-bust dynamics – the rise of a population to outbreak levels, followed by a dramatic decline – have been associated with biological invasions and offered as a reason not to manage troublesome invaders. However, boom-bust dynamics rarely have been critically defined, analyzed, or interpreted.
How is Lincoln-Peterson model used in population ecology?
This advanced model assumes familiarity with the Lincoln-Peterson estimate of population size. It is designed to be used in exploring how factors such as population distribution, trap experience (learning to avoid or seek out traps), population size, and sampling effort can affect the precision and accuracy of the estimate.
How is population ecology used in real life?
It is designed to be used in exploring how factors such as population distribution, trap experience (learning to avoid or seek out traps), population size, and sampling effort can affect the precision and accuracy of the estimate. ⇒Links to older versions of each model are found here.
