Procesos a Escala del Huésped y del Microbio Moldean Conjuntamente la Variación Espacial de Wolbachia Asociada a
Research square
|February 6, 2026
Resumen
Los procesos espaciales a escalas del huésped y del microbio dan forma a los microbios asociados al huésped como Wolbachia en las hormigas. La selección ambiental y la dispersión interactúan en estas escalas, influyendo en la distribución microbiana.
Área de la Ciencia:
- Ecología
- Microbiología
- Biología Evolutiva
Sus antecedentes:
- Los microbios asociados al huésped (MA) se enfrentan a la selección y la dispersión tanto a escala microbiana como a escala del huésped.
- Los microbios MA deben adaptarse al microambiente de su huésped y al macroambiente que habita el huésped.
- La dispersión ocurre tanto entre huéspedes (escala microbiana) como a través del movimiento del huésped (escala del huésped).
Objetivo del estudio:
- Investigar cómo los procesos espaciales a escala del huésped y del microbio influyen en la distribución de los endosimbiontes de Wolbachia.
- Comprender la variación espacial de los microbios asociados al huésped (MA), que es más compleja que la de los organismos de vida libre.
Principales métodos:
- Se examinó la variación espacial en la abundancia relativa de Wolbachia en hormigas huésped y linajes de huéspedes.
- Se evaluaron las correlaciones entre la selección ambiental a escala del huésped y del microbio.
- Se utilizaron las distribuciones de linajes de huéspedes y los datos de co-ocurrencia para desentrañar los procesos dependientes de la escala.
Principales resultados:
- Se observó una variación espacial significativa en la abundancia de Wolbachia tanto a escala del huésped (paisaje) como a escala del linaje microbiano.
- Se encontró una correlación entre la selección ambiental a escala del huésped y del microbio, lo que complica la evaluación de efectos aislados.
- Se demostró que los procesos a escala del huésped y del microbio contribuyen a la variación espacial en el sistema de hormigas estudiado.
Conclusiones:
- La variación espacial de los microbios MA está gobernada por factores interactuantes en múltiples escalas.
- La comprensión de la ecología espacial de los microbios MA requiere la consideración de procesos tanto a nivel microbiano como del huésped.
- La complejidad de las distribuciones espaciales de los microbios MA se deriva de la interacción de la selección y la dispersión en distintas escalas.

What is Variation?
18.6K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

Variation
8.0K
An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation, which is the square root of variance.
When independent and dependent variables are plotted on a scatter plot, the slope of a line is a value that describes the rate of change between the two...

Conservative Site-specific Recombination and Phase Variation
6.8K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

Structural Joints: Synovial Joints
7.0K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

pH Scale

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Structural Joints: Fibrous Joints
3.8K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.

All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
