Resumen

Investigadores han identificado a Vibrio pectenicida como la bacteria responsable de la muerte masiva de estrellas de mar a lo largo de la costa del Pacífico desde 2013.

Desde 2013, una enfermedad misteriosa ha provocado la muerte de más de 5 mil millones de estrellas de mar a lo largo de la costa del Pacífico de América del Norte, afectando gravemente a más de 20 especies. La estrella de mar girasol, en particular, experimentó una disminución poblacional de aproximadamente el 90% durante los primeros cinco años del brote.

Investigaciones recientes han identificado a la bacteria Vibrio pectenicida como la causa de esta enfermedad de desgaste en estrellas de mar. La enfermedad se manifiesta a través de lesiones, pérdida de brazos y eventual desintegración de los cuerpos de las estrellas de mar. Los hallazgos fueron publicados en la revista Nature Ecology & Evolution.

La pérdida de estrellas de mar ha provocado una sobrepoblación de erizos de mar, lo que a su vez ha devastado los bosques de algas kelp, hábitats críticos para numerosas especies marinas. Comprender la causa bacteriana de la enfermedad es un paso significativo hacia el desarrollo de estrategias de conservación, como la cría de estrellas de mar resistentes a la enfermedad y la restauración de los ecosistemas afectados.

✓

Confirmed

Since 2013, a mysterious disease has led to the death of over 5 billion sea stars along the Pacific coast of North America, severely impacting more than 20 species.

✓

Confirmed

The sunflower sea star, in particular, experienced a population decline of approximately 90% within the first five years of the outbreak.

✓

Confirmed

Recent research has identified the bacterium Vibrio pectenicida as the cause of this sea star wasting disease.

✓

Confirmed

The disease manifests through lesions, arm loss, and eventual disintegration of the sea stars' bodies.

✓

Confirmed

The findings were published in the journal Nature Ecology & Evolution.

✓

Confirmed

The loss of sea stars has led to an overpopulation of sea urchins, which in turn has devastated kelp forests—critical habitats for numerous marine species.

✓

Confirmed

Understanding the bacterial cause of the disease is a significant step toward developing conservation strategies, such as breeding disease-resistant sea stars and restoring affected ecosystems.
