Asexual reproduction strategies and blooming potential in Scyphozoa [PDF]
, 2014 Scyphistomae show different modes of propagation, occasionally allowing the sudden release of great numbers of medusae through strobilation leading to so-called jellyfish blooms.

Is Parthenogenesis Sexual or Asexual Reproduction? [PDF]
Nature, 1950 CYTOLOGISTS and others commonly refer to parthenogenesis as asexual reproduction. This usage is, for example, to be found in the books of Wilson1, Darlington2, and White3, along with the facts that indicate that parthenogenesis is a derivative of normal sexual reproduction.

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes
Advanced Science, EarlyView.In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

The mutational meltdown in asexual populations [PDF]
, 1993 Loss of fitness due to the accumulation of deleterious mutations appears to be inevitable in small, obligately asexual populations, as these are incapable of reconstituting highly fit genotypes by recombination or back mutation. The cumulative buildup of
