Evolutionary Ecology, 2018
Reproduction is intimately linked with dispersal, but the effects of changes in reproductive strategies on dispersal have received little attention. Such changes have occurred in many taxonomic groups, resulting in profound alterations in life-history.

Reconstructing the reproductive mode of an Ediacaran macro-organism [PDF]
Nature, 2015 Enigmatic macrofossils of late Ediacaran age (580-541 million years ago) provide the oldest known record of diverse complex organisms on Earth, lying between the microbially dominated ecosystems of the Proterozoic and the Cambrian emergence of the modern

Rensch's rule relates to a pattern whereby sexual size dimorphism (SSD) is more female-biased in small-sized species and more male-biased in large-sized ones.

Reproductive Criteria of Multicellularity and Original Modes of Reproduction
Успехи современной биологии, 2023The reproductive criteria of multicellularity are proposed for the first time. Terminologically the multicellularity is advised to subdivide into three variants: 1) protonemal – the most primitive, known in multicellular prokaryotes, in majority groups of multicellular algae and in gametophytes of some embryophyte plants; 2) siphonoseptal, distributed ...

Reproduction mode and crop improvement
Theoretical and Applied Genetics, 1968The author has tried to accumulate data on the reproduction modes of crop plants: autogamy and allogamy in the case of sexuality, involving self-fertility and self-sterility, and different means of vegetative propagation and apomixis. In combination with the state of ploidy and the basic chromosome number the different modes of reproduction exert a ...

Progress on reproductive modes of sarcosaphagous flies
Journal of Asia-Pacific Entomology, 2021Abstract The reproduction strategies of invertebrates, oviparity, ovoviviparity and viviparity, always reflect the relationship between individuals and their surroundings. There is plasticity in the reproductive strategies of sarcosaphagous flies as they adjust to rapidly changing circumstances.

Alternative Modes of Reproduction
1989The past decade has witnessed the birth of new reproductive technologies (such as in vitro fertilization) and the application of older technologies to new situations (such as the use of artificial insemination to facilitate surrogate motherhood).

Anuran Reproductive Modes: Evolving Perspectives
Journal of Herpetology, 2015Abstract Although most of the unique ways that frogs reproduce were described in the 1800s and 1900s, additional modes are still being discovered in the 21st Century. The concept of reproductive mode has evolved from descriptive natural history to an integration of developmental biology, genetics, systematics, evolution, ecology, behavior, and ...

By far, sexual reproduction is the more common pattern among living vertebrate forms and its widespread occurrence suggests that it is the plesiomorphic, or primitive, reproductive mode among the vertebrates. In all sexually reproducing forms, parental genomes that lie within an individual recombine to produce specialized sex cells containing one half ...
