Una plaga de erizos marinos est?? terminando con los bosques de algas californianos, y las nutrias locales podr??an ser la clave para terminar el problema.<\/h2>\n\n\n\n

Desde 2013, una serie de??cambios medioambientales<\/strong>??ha orillado a los bosques de algas californianos a desaparecer. Lenta e inevitablemente, las plantas del ecosistema marino han reducido sus n??meros en un??alarmante 95 %<\/strong>, dejando a las especies que dependen de ellas desprotegidas y sin recursos para alimentarse. Podr??a ser que las??nutrias sean las ??nicas<\/strong>??que puedan librar una batalla contra esta??devastaci??n<\/strong>.<\/p>\n\n\n\n

Durante a??os, las nutrias marinas han sido los depredadores naturales de los erizos de mar<\/strong>. Estos animales espinosos se alimentan de las plantas subacu??ticas, que generalmente son algas. De esta manera, las poblaciones de esta especie se mantienen equilibradas<\/strong> con la presencia de las nutrias, quienes los eligen como base de su alimentaci??n<\/strong>.<\/p>\n\n\n\n

Desde hace poco m??s de 8 a??os, los bosques de algas marinas en California van visto una merma dram??tica. Donde antes hab??a vastas ??reas verdes, ahora s??lo se encuentran p??ramos de erizos<\/strong>.PUBLICIDAD<\/p>\n\n\n\n

Las profundidades marinas ahora s??lo se ven moradas ???dada la coloraci??n de los erizos<\/strong>???, porque no hay algas<\/strong> que las revistan de su verde t??pico. Podr??a ser que la ciencia ya tenga una respuesta a esta devastaci??n progresiva y aparentemente incontrolable.<\/p>\n\n\n\n

???Desgaste de las estrellas de mar???<\/h2>\n\n\n\n

Este decrecimiento no es una casualidad. <\/strong>De acuerdo con Joshua Smith, estudiante graduado de UC Santa Cruz<\/strong>, proviene de un fen??meno que nombr?? ???desgaste de las estrellas de mar??? a lo largo de la costa oeste. Entre las especies m??s afectadas por esto es la estrella de mar girasol, que es otro de los depredadores de erizo de mar:<\/p>\n\n\n\n

Seg??n el autor, los trozos de algas marinas caen a la deriva sobre el arrecife como hojas que caen en un bosque. <\/strong>De esta manera, los erizos de mar se alimentan de las algas ca??das desde las rocas en las profundidades, que usan como guarida y hogar.<\/p>\n\n\n\n

Naturalmente, las algas viven saludables en entornos fr??os y ricos en nutrientes<\/strong> que existen en el oc??ano. Si las condiciones son las adecuadas, t??picamente pueden crecer hasta 30 cent??metros diarios<\/strong>. Este crecimiento se fren?? por el calentamiento de las aguas<\/strong>, que azot?? el Pac??fico sin precedentes.<\/p>\n\n\n\n

Como consecuencia de la falta de algas, los erizos se vieron forzados a subir a la superficie para buscar alimento. As??, poco a poco, devastaron los bosques de algas<\/strong> que exist??an en California. De esta forma, la especie prolifer?? a ritmos que nunca antes lo hab??a hecho, dejando a las nutrias con demasiadas presas que cazar.<\/p>\n\n\n\n

El??problema podr??a extenderse<\/strong>??hasta M??xico y Alaska, ya que las corrientes de aguas marinas se seguir??n calentando??como consecuencia del cambio clim??tico.??<\/strong>Por esta raz??n, las nutrias son las ??nicas que pueden controlar esta plaga de erizos marinos, que est??n acabando con las algas californianas.<\/p>\n\n\n\n
