This will be done by initially isolating relevant species from Sri Lankan coastal water. of the selected species under ambient and future oceanographic settings. The two PIs will jointly be responsible for all the scientific experiments. The r.

r/K-selektion är en biologisk teori som säger att en organism antingen kan maximera sin avkommas överlevnadschanser till priset av att antalet ättlingar blir litet

K-selection is relative. A species is only K-selected in comparison with a more r-selected species, e.g.: Most invertebrates These differences are paraphrased by the classic r-selected vs. K-selected life species of spiny lobsters with contrasting reproductive systems: a temperate Large number of smaller offspring with little parental care (r-selected species). Fewer r selection. Time.

R- selected species are those species that can survive in unstable, unpredictable environmental conditions and produce large number of small size offspring. These offspring have low survival rate ( short life span) and do not have any parental care. These species grow very rapidly and attain reproductive maturity at early stage in their lives.

C, N, P Which of r- and k-selected species produce more offspring?

r-selected species can also be said to conform to the “ruderal strategy” (Table 7). R-Strategists, Table 7. A comparison of the characteristics of r-selected and K-

R-Selected Species. weak competitive ability. R-Selected Species. variable population size, often well below carrying capacity. R-Selected Species in Temperate Deciduous Forest Characteristics: density-independent: many offspring for better chance of survival, low energy investment in offspring, small young Examples: White Tailed Squirrel, Eastern Chipmunk, Carpenter Bees (Xylocopa) Those organisms described as r-strategists typically live in unstable, unpredictable environments. Here the ability to reproduce rapidly (exponentially) is important. Such organisms have high fecundity (glossary) and relatively little investment in any one progeny individual, they are typically weak and subject to predation and the vicissitudes of their environment.

Edit. Edit. R-Selected Species DRAFT. 2 months ago In contrast, r-selected species have a large number of small offspring (hence their r designation (see the table below). This strategy is often employed in unpredictable or changing environments. Animals that are r -selected do not give long-term parental care and the offspring are relatively mature and self-sufficient at birth. Slide 12 of 52 Examples of R-Selected Species.

Selected recent publications: Zaher, H. The five selected species occupy different habitats, which may influence their exposure to microplastics, enabling R2: R-squared - Coefficient of determination.

Such species are also generally not very invested in protecting or rearing these young. R-selected species, also referred to as r-strategist, are species whose populations are determined by their maximum reproductive capacity (biotic potential). R-selected species are those that produce many offspring that have a lower probability of surviving to adulthood.
