R- Selected species have high population densities while k-selected species have lower population densities
An r-selected species is a species that has a high reproductive rate and produces many offspring with little parental care. These species are adapted to environments where resources are abundant and unpredictable, allowing them to maximize their reproductive success by producing many offspring. Examples of r-selected species include insects like mosquitoes and weeds.
r-selected species have a high reproductive rate, producing many offspring with little parental care in unstable or unpredictable environments. K-selected species have a low reproductive rate, producing few offspring with high parental care in stable environments. r-selected species often have a quick maturation and short lifespan, while K-selected species have a slower maturation and longer lifespan.
K-selected
K-selected and r-selected reproductive strategies differ in their impact on population growth and survival. K-selected species have fewer offspring but invest more resources in each individual, leading to slower population growth but higher survival rates. In contrast, r-selected species produce many offspring with minimal parental care, resulting in rapid population growth but lower individual survival rates.
R-selected species are those that prioritize high reproductive rates and produce many offspring with little parental investment, thriving in unstable or unpredictable environments. They tend to have shorter lifespans, mature quickly, and are often found in habitats where resources are abundant but unpredictable. In contrast, K-selected species invest more in fewer offspring, providing greater parental care and support, which increases the survival chances of their young. These species are typically found in stable environments where competition for limited resources is high.
K-selected species are present in environments that are predictable and where resources aren't necessarily fought over. A k-selected species will produce less frequently and with few children than an R (or S) selected species. It's the concept of quality over quantity. K-selected species are typically bigger, take longer to reach maturity, and live longer.
R-selected species typically have high reproductive rates, produce many offspring with little parental care, and have short lifespans. They are adapted for rapid population growth in unstable environments. K-selected species, on the other hand, have low reproductive rates, produce few offspring with high parental care, and have long lifespans. They are adapted for stable environments with limited resources.
R-selected species typically have high reproductive rates, producing many offspring with little parental care. They are adapted for rapid population growth in unstable environments. In contrast, K-selected species have lower reproductive rates, producing fewer offspring with more parental care. They are adapted for stable environments with limited resources, focusing on the survival and success of each individual offspring.
The burrowing owl is generally considered to be r-selected. This classification is due to its reproductive strategy, which involves producing a relatively high number of eggs and offspring in a short period, along with a tendency for lower parental investment per offspring. These traits are characteristic of r-selected species, which often thrive in unstable environments where maximizing reproductive success is crucial.
An r-selected species is characterized by high reproductive rates, producing many offspring with relatively low parental investment. These species typically thrive in unstable or unpredictable environments where rapid population growth is advantageous. Examples include insects, rodents, and some fish species. Their strategy focuses on maximizing reproductive success in a short time frame, often at the expense of individual offspring survival.
Because of their inability to reproduce rapidly, "k"-selected species tend to be more sensitive to change and are, therefore, less able to adapt to a rapidly changing environment. This is what makes them susceptible to endangerment. - See more at: http://www.chacha.com/question/why-are-pest-species-likely-to-be-extreme-r%26%2345%3Bselected-species#sthash.E2Anrl2s.dpuf
