Asexual Reproduction in Sponges: A Review
Molecular Reproduction and DevelopmentABSTRACT Sponges (phylum Porifera) are an early‐branching lineage of Metazoa. The long independent evolution of sponges makes them an essential group for comparative studies of the emergence and early evolution of various aspects of metazoan biology, including asexual reproduction.

ARO: A new model-free optimization algorithm inspired from asexual reproduction
Applied Soft Computing Journal, 2010 This paper proposes a new individual based optimization algorithm, which is inspired from asexual reproduction known as a remarkable biological phenomenon, called as Asexual Reproduction Optimization (ARO).

Constraints on the evolution of asexual reproduction
BioEssays, 2008AbstractSexual reproduction is almost ubiquitous among multicellular organisms even though it entails severe fitness costs. To resolve this apparent paradox, an extensive body of research has been devoted to identifying the selective advantages of recombination that counteract these costs.

Asexual Reproduction in a Sipunculan Worm
Science, 1970The sipunculan worm Aspidosiphon brocki reproduces asexually by transverse fission into two unequal parts, the smaller part comprising the posterior fifth of the animal. Prior to fission each part regenerates the structures essential to the formation of a new individual.

Asexual reproduction of planarians: Metric studies
Russian Journal of Developmental Biology, 2006A relationship was studied between fission and restoration of body and its individual parts under different experimental conditions in planarians of the Dugesia tigrina asexual race. The body and its fragments were studied morphomterically. After fission, the growth of planarians demonstrated topographic differences.

Asexual Reproduction in Coleochaete
Botanical Gazette, 19281. The opening through which the swarm spore escapes is made by some chemical change, probably enzymatic, which is initiated and controlled by the chloroplast. 2. Zoospores escape by an amoeboid movement through a pore. 3. There is a period of quiescence after the escape of the spore, at the end of which the cilia appear. 4.

Asexual reproduction in the suctorianDiscophrya collini
Protoplasma, 1982Discophrya collini reproduces asexually through the formation of a ciliated swarmer by evaginative budding. This process is initiated by the repeated replication of a single subcortical kinetosome to form a kinetosome field. The epiplasm of the multilayered cortex covering this field becomes reduced in thickness and the whole cortex invaginates to ...

Asexual reproduction in Phytophthora erythroseptica
Transactions of the British Mycological Society, 1966Sporangia are readily produced by Phytophthora erythroseptica Pethybr. when mycelial mats are grown in pea broth, washed and transferred to shallow layers of water or Petri's solution. Sporulation occurs between 8 and 26 ° C., (opt. c . 18–22 ° C.). Aeration of water is not necessary for sporangial production.
