Master of Puppets: How Microbiota Drive the Nematoda Ecology and Evolution?
The nematode microbiota can influence life‐history traits, thereby shaping the species' ecology and evolutionary trajectories. ABSTRACT In recent decades, the microbiota has emerged as a key driver of biological functions in metazoans, and nematodes are no exception.

Linking phenotypic variation to patterns of genetic isolation along a speciation continuum
Abstract Investigating taxa at varying stages of divergence can shed light on the evolutionary forces that lead to reproductive isolation and eventual speciation. The forces promoting isolation vary in space and time, which makes it difficult to reconstruct the trajectory that resulted in the divergence observed among species today.

[Sporogenesis, sporoderm and mature spore ornamentation in Lycopodiaceae].
Estudios sobre aspectos reproductivos, morfología y ultraestructura de las esporas de Lycopodiaceae no son abundantes en la literatura científica y constituyen información esencial para apoyar las relaciones taxonómicas y sistemáticas en el grupo. Con el fin de completar la información existente, añadiendo contribuciones nuevas y más amplias sobre ...

ON THE NATURE OF SPOROGENESIS IN SOME AEROBIC BACTERIA [PDF]
Washed vegetative cells of various species of aerobic spore-forming bacteria sporulate abundantly when shaken in distilled water in air. The spores thus formed possess the same heat resistance as spores formed in a complete growth medium. Various factors influencing sporogenesis in water are described. Glucose in low concentration completely suppresses
