Starfish that reproduce through cloning avoid ageing to a greater extent than those that propagate through sexual reproduction.
This is shown by a new research study in which researchers from the University of Gothenburg participated. The study has recently been published in the highly respected journal Heredity.
In the study, researchers investigated the telomere lengths and population genetics of a starfishCoscinasterias tenuispina. The telomeres are located at the ends of the chromosomes, and affect the lifespan and health of an individual.
The studied starfish exhibited both asexual and sexual reproduction. Asexual reproduction, or cloning, involves the starfish dividing itself into two or more parts, after which the new parts regenerate.
The researchers wanted to find out whether the populations that clone themselves the most have better health and signs of delayed ageing in relation to the populations that carry out more sexual reproduction. Both Mediterranean and Atlantic populations were studied.
In the Atlantic, however, sexual reproduction is more common. The principle behind the study, that clones avoid ageing by regulating telomeres, has also been previously studied by other researchers in flatworms. Fewer children mean longer life? The study was published in the May issue of Heredity: New research into ageing processes, based on Starfish reproduction asexual plants genetic techniques, confirms theoretical expectations about the correlation between reproduction and lifespan.
Studies of birds reveal that those that have offspring later Animals that reproduce asexually by somatic cloning have special mechanisms that delay ageing provide exceptionally good health. Scientists at the University of have shown how colony-forming ascidians or sea squirts Starfish have strange talents. Two biology students from University of Southern Denmark have revealed that starfish are able to squeeze foreign bodies along the length of their body cavities and out through their arm tips.
Cod are among Sweden's most common and most popular edible fish and have been fished hard for many years. One consequence is the risk of serious changes in cod stocks, reveals research from the University of Gothenburg, Sweden.
Imagine how easy life would be if you could produce offspring without a mate. Sexual reproduction is the most Starfish reproduction asexual plants mating system in the animal kingdom. But in many species, females do not require males to produce offspring New research from the University of East Anglia shows that an evolutionary force known as 'sexual selection' can explain the persistence of sex as a dominant mechanism for reproducing offspring.
Technology first used by NASA to grow plants extra-terrestrially is fast tracking improvements in a range of crops. Scientists at John Innes Centre and the University of Queensland have improved the technique, known as speed His new research describes the Cells replicate by dividing, but scientists still don't know exactly how they decide when to split.
Deciding the right time and the right Starfish reproduction asexual plants to divide is critical for cells — if something goes wrong it can have a big New analysis of the structure and function of the naturally-occurring antimicrobial agent tunicamycin has revealed ways to produce new, safe antibiotics for Mycobacterium tuberculosis and other disease-causing bacteria.
