On the other hand, it highlights the need for a special effort to be made in prevention, since the eradication of invasive species is shown to be excessively costly and complicated, especially in the marine environment. <\/p>\n<p>The aim of this initiative has been to determine the expansion dynamics of three invasive allochthonous algae, Caulerpa racemosa, Lophocladia lallemandii and Womersleyella setacea in the Cabrera Archipelago National Park, as well as to verify their effects on marine communities. Thus, the CSIC has studied the distribution and abundance of these species, as well as the organisms that favor their invasion. <\/p>\n<p>From this project it can be deduced that Lophocladia lallemandii is distributed between 5 and 35 meters deep, displacing communities of photophilic algae, hemisciaphyllous algae and meadows of Posidonia oceanica. On the other hand, Caulerpa racemosa has a greater biomass and cover between 25 and 50 meters deep, negatively affecting the detrital and ma\u00ebrl bottoms, the coralligenous and hemisciaphyllous algae communities. On the other hand, Womersleyella setacea always develops below 25 meters, altering the communities of coralligenous and hemisciaphyllous algae.  <\/p>\n<p>Another fact confirmed by the scientists who have prepared this study is that sexual reproduction has only been observed in Lophocladia lallemandii, which favors its rapid expansion and currently makes it difficult to implement measures capable of stopping its dispersal. The other two species reproduce vegetatively through the dispersal of small fragments, so their progress, and especially in the case of Caulerpa racemosa, is probably favoured by fishing gear. &nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"author":11,"featured_media":0,"template":"","meta":{"_acf_changed":false},"palabras_clave":[],"class_list":["post-97857350","actualidad_home","type-actualidad_home","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.9 -
