Resumen
Una alga no nativa de rápido crecimiento, Caulerpa taxifolia, ha invadido una laguna de San Diego. Esto marca el primer gran esfuerzo de Estados Unidos para erradicar una incipiente invasión de especies marinas.
Área de la Ciencia:
- Biología marina Biología marina.
- Ecología de las especies invasoras ecología de las especies invasoras
Sus antecedentes:
- Se ha descubierto una floración significativa de algas de color verde brillante, identificadas como Caulerpa taxifolia, en una laguna de San Diego.
- Esta alga es un clon no nativo y de rápido crecimiento responsable de la devastación ecológica en el Mar Mediterráneo.
Objetivo del estudio:
- Para informar sobre el descubrimiento de una incipiente invasión de especies marinas por Caulerpa taxifolia en una laguna de los Estados Unidos.
- Para esbozar la respuesta inmediata y los esfuerzos de erradicación que se están llevando a cabo.
Principales métodos:
- Monitoreo ecológico e identificación de las especies de algas.
- Implementación de medidas de contención, incluido el cordón de la laguna afectada.
- Desarrollo de una estrategia de erradicación que implique el tratamiento químico (envenenamiento) de las algas.
Principales resultados:
- Descubrimiento de un gran parche de Caulerpa taxifolia, una alga marina altamente invasiva.
- Confirmación de la fuerte sospecha de que las algas son el mismo clon que está devastando los ecosistemas mediterráneos.
Conclusiones:
- La presencia de Caulerpa taxifolia representa una amenaza ecológica significativa que requiere una intervención inmediata.
- Este evento hace necesario el primer gran intento de Estados Unidos para detener una incipiente invasión de especies marinas, con planes para erradicar químicamente las algas.

01:19Other Algae
The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...
01:21Green Algae
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
01:28Overview of Algae
The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...
01:23Red Algae
Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
01:39Keystone Species
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a pivotal role in the...
01:50Threats to Biodiversity
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
