In danger: microbiome decides on reproduction!

In danger: microbiome decides on reproduction!

jellyfish are among the oldest animals on earth and are present in all oceans. Microbiologists of Christian-albrechts-Universität zu Kiel (CAU) have examined the asexual reproduction of the ear whom (Aurelia Aurita). This research shows that bacterial products, especially beta-carotene, play a central role in this reproductive process. Beta-carotene is produced by microbes in the microbioma.

If these microorganisms are missing, the Strobilation process, i.e. the transformation of the polyp to young meduses, comes to a standstill. This leads to developmental disorders and greatly reduced reproduction. The results of this study were published in the journal Iscience and illustrate the close connection between the development of Mariner Organisms and its bacterial partners. The microbiome influences the fitness and health of many marine life.

The role of the microbiome

The microbioma of the ear wheels is remarkably versatile and can adapt to different environmental conditions. The life cycle of this jellyfish includes tiny larvae that develop into stuck polyps. This is followed by the Strobilation, which creates Ephyren, which finally grow into meduses. The influence of the microbiome is particularly important before the striking.

beta-carotene is converted into retinic acid in the body of the bodies, which activates central genes for Strobilation. Laboratory experiments with sterile polyps showed developmental disorders that could be remedied by adding beta-carotene or retinic acid. This underlines the essential role of the microbiome in the development of the ear whom.

microplastics as a threat

Another, pressing problem is the microplasty that has become a serious threat to marine ecosystems in recent years. According to thermoplastic composites , microplastics often come from the larger plastic parts that get into the oceans and the health of fishing and other marine animals endanger.

microplastics can cause physical blockages in the digestive system of sea creatures and release toxic chemicals. Many marine organisms confuse microplastics with food, which leads to a decline in populations. Every year, over ten million tons of plastic waste reach the oceans. This not only endangers biodiversity, but also changes the microbial community and disturbs the nitrogen cycle in the sea.

long -term consequences and necessary measures

The serious long -term consequences of microplastics on the food chain are evident because small organisms are eaten by larger animals. This problem is reinforced by the fact that microplasty can promote toxic algae flowers and impair water quality. Research on microplastics shows that contamination with plastic parts can also cause health problems in humans if contaminated fish and sea fruits are consumed.

In order to protect the health of the oceans, measures to reduce plastic waste are essential. Consumers are asked to minimize their plastic consumption, while governments should introduce stricter regulations on plastic production and disposal. Innovative solutions such as biodegradable materials and improved recycling practices are necessary to address these challenges.

Understanding the interactions between microbes, jellyfish and microplastics is crucial to develop effective protective measures and to preserve the endangered marine ecosystems. Common action is required to reduce the pollution of the oceans and to secure the health of the planet in the long term.
