30 Jul 2018 The r/k selection theory explains whether a species chooses to be a Common examples of k-strategists species include humans, lions and

Examples of R-selected species are: Bacteria Oysters Weeds Mice Rabbits Jellyfish Dandelions Insects such as Mosquitoes, House flies, Daphnia and Goldenrod. R-selected species usually don't care for offspring, whereas k-selected species such as orangutans will provide care (orangutan offspring live with their mothers for up to eight years). Examples include rabbits, bacteria, salmon, plants such as weeds and grasses, etc. Many insects are r-selected. For example, ants can be considered r-selected. For example, other types of frogs, such as the red eyed tree frog or toads, may need to find their food in insects just like the Flying Frogs do. This in turn causes a competition for insects.

K-Selected use the opposite view of Quality in a stable environment R-selected species usually don't care for offspring, whereas k-selected species such as orangutans will provide care (orangutan offspring live with their mothers for up to eight years). Examples include rabbits, bacteria, salmon, plants such as weeds and grasses, etc. This 6 minute video explains the Difference between r-selected and k-reproductive strategies. For captions, Please click on the 'CC' button next to the gear Surviorship curves give us additional insight into r and K-selected strategies. Notice that the vertical axis of the survivorship plots is on a log scale and that horizontal axis is scaled to the maximum lifetime for each species. One of the interesting differences between r and K strategists is in the shape of the survivorship curve. Invasive species Mostly affected by invasive species Most invasive species are r selected because they reproduce quickly Examples.

2017-11-06 · These species often have short life expectancies, produce as many offspring as they can, and invest very low amounts of parental care. R-selected species can include mosquitos, mice, and bacteria.

Weedy species remain small and have a brief life span, perhaps passing a few generations in the light gap before it closes. Examples: Oysters, Insects (Mosquitos, Daphnia, Goldenrod) Labels: K Selected Species , r selected species , r Selected Species examples. Newer Post Older Post Home.

This concept leads in to the natural selection process: the species that cannot survive and reproduce, or the "loser" when competing, will not be favored in natural selection.
