Resumen
La abeja social Trigona hypogea consume únicamente carroña para obtener proteínas, ya que carece de polen almacenado. Las secreciones glandulares proporcionan nutrientes esenciales, lo que muestra una adaptación evolutiva a la necrofagia en esta especie de abeja.
Área de la Ciencia:
- Entomología Entomología.
- Biología evolutiva Biología evolutiva.
- Comportamiento animal Comportamiento animal.
Sus antecedentes:
- Las abejas sociales generalmente dependen del polen para obtener proteínas.
- Trigona hypogea, una abeja social, muestra hábitos alimenticios inusuales.
- Comprender las adaptaciones dietéticas en los insectos sociales es crucial para los estudios evolutivos.
Objetivo del estudio:
- Para investigar la fuente de proteínas de la abeja social Trigona hypogea.
- Para determinar si Trigona hypogea utiliza carroña como sustituto de proteínas para el polen.
- Para explorar las implicaciones evolutivas de la necrofagia en Trigona hypogea.
Principales métodos:
- Observación del comportamiento de búsqueda de alimento y provisión de nidos.
- Análisis de las provisiones larvales para el contenido de polen.
- Evaluación de las secreciones glandulares para el contenido de proteínas.
Principales resultados:
- Los nidos de Trigona hypogea y las provisiones larvales carecen de polen.
- Las abejas obreras muestran corbiculas reducidas, estructuras para el transporte de polen.
- Las secreciones glandulares contienen aproximadamente un 20 por ciento de proteína, lo que sugiere un sustituto del polen.
Conclusiones:
- Trigona hipogea ha desarrollado la necrofagia, utilizando carroña como su principal fuente de proteínas.
- Adaptaciones especializadas, incluyendo mandíbulas dentadas y comportamientos de reclutamiento, apoyan esta estrategia de alimentación única.
- Esto representa una divergencia significativa de las típicas estrategias nutricionales de las abejas.

Altruism
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
Microbial Interactions: Cooperation
Microbial cooperation involves beneficial interactions in which different species work together for individual or mutual advantage. These interactions can profoundly influence ecological dynamics and evolutionary processes, and they are essential to many pathogenic and symbiotic relationships.Nematode–Bacteria CooperationA striking example is the relationship between the Gram-negative bacterium Xenorhabdus nematophila and the parasitic nematode Steinernema carpocapsae. Juvenile nematodes...
Microbial Interactions: Predation
Microbial predation refers to the process by which one microorganism kills and consumes another to obtain nutrients and energy. It encompasses both bacterial and protozoan predators. This interaction plays a crucial role in shaping microbial communities and regulating nutrient cycling.Bacterial Predators: Epibiotic vs. EndobioticBacterial predators are classified based on their mode of attack as either epibiotic or endobiotic. Epibiotic predators, such as Vampirococcus, attach to the surface of...
Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

Phagocytosis
Cells pull particles inward and engulf them in spherical vesicles in an energy-requiring process called endocytosis. Phagocytosis (“cellular eating”) is one of three major types of endocytosis. Cells use phagocytosis to take in large objects—such as other cells (or their debris), bacteria, and even viruses.The objective of phagocytosis is often destruction. Cells use phagocytosis to eliminate unwelcome visitors, like pathogens (e.g., viruses and bacteria). It is perhaps unsurprising, that many...
