Orientación del dosel: un nuevo tipo de orientación en las hormigas
Science (New York, N.Y.)
|October 3, 1980
Resumen
Las hormigas Paltothyreus tarsatus usan patrones de dosel, no señales celestiales como el sol, para una localización precisa. Esta estrategia de orientación es efectiva en la tenue luz de los bosques tropicales africanos.
Área de la Ciencia:
- Comportamiento animal Comportamiento animal.
- Navegación de los insectos.
- Ecología sensorial ecología sensorial.
Sus antecedentes:
- Las hormigas a menudo confían en varias señales para la navegación, incluida la luz celestial y los puntos de referencia.
- Comprender los mecanismos de navegación es crucial para comprender la ecología y el comportamiento de los insectos.
Objetivo del estudio:
- Para investigar las señales de orientación primarias utilizadas por Paltothyreus tarsatus foragers.
- Para determinar la influencia de las señales celestiales frente a las características ambientales en el rastreo de hormigas.
Principales métodos:
- Realizó experimentos de campo y de laboratorio con Paltothyreus tarsatus.
- Evaluó el impacto de las señales celestes manipuladas (sol, luz polarizada) y los patrones de dosel en el comportamiento de búsqueda.
Principales resultados:
- Las señales celestes no mostraron ningún efecto detectable en la orientación de búsqueda de P. tarsatus.
- Se identificaron patrones de dosel como una influencia importante en la orientación de la gama de hogar de esta especie de hormiga.
Conclusiones:
- P. tarsatus foragers utiliza principalmente patrones de dosel para la navegación, especialmente bajo las condiciones de poca luz de los bosques tropicales.
- Esta dependencia de los patrones de dosel sugiere una adaptación al entorno visual específico de los bosques africanos.

02:40Epiphytes, Parasites, and Carnivores
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the biosynthesis of the...
02:57Attachment of Sister Chromatids
As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules. Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall of a...
01:39Mechanism of Filopodia Formation
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

01:21Chemotaxis and Direction of Cell Migration
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon towards...
01:23Surface Appendages of Archaea
Archaeal surface appendages are highly specialized structures essential for environmental adaptation, encompassing roles in adhesion, biofilm formation, and motility. Among these appendages, pili and archaella stand out for their distinct morphologies and functionalities, enabling archaea to thrive in diverse and often extreme environments.Pili: Adhesion and Biofilm FormationPili are filamentous structures assembled from pilin protein subunits, primarily contributing to adhesion and biofilm...
01:30Oriented Surfaces
A surface is called orientable if a consistent choice of unit normal vector can be made at every point on the surface. A thin soap film stretched across a wire loop provides a familiar example. The film separates the air on one side from the air on the other, so one side can be selected as positive and the opposite side as negative. Once this choice is made, a unit normal vector can be assigned smoothly across the entire surface.At each point on the soap film, a unit normal vector points...
