Shifts among Eukaryota, Bacteria, and Archaea define the vertical organization of a lake sediment [PDF]
Background Lake sediments harbor diverse microbial communities that cycle carbon and nutrients while being constantly colonized and potentially buried by organic matter sinking from the water column.

Conditions for minimal intelligence across eukaryota: a cognitive science perspective [PDF]
What is minimal intelligence? Generally speaking, our understanding of intelligence has to do with sets of biological functions of organisms that exhibit a degree of flexibility against contingencies in their environment-induced behavioral repertoire.

Intestinal microbiota is involved in immune response and metabolism of the host. The frequent use of anthelmintic compounds for parasite expulsion causes disturbance to the equine intestinal microbiota.

The evolutionary emergence of the primitive gut in Metazoa is one of the decisive events that conditioned the major evolutionary transition, leading to the origin of animal development.

Early evolution of the Eukaryota [PDF]
The evolution of eukaryotes represents one of the most fundamental transitions in the history of life on Earth; however, there is little consensus as to when or over what timescale it occurred.

Alternative pathway (cyanobacteria to eukaryota)
It is quite evident from the fossil record that prokaryotic cells were the first cell type evolved. After a long interval of nearly two billion years eukaryotic cells appeared. There is little doubt that this cell type arose from the bacterial cell. How this occurred has been the subject of much speculation.

Universal and Lineage-Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms. [PDF]
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Temperature and light mainly drive seasonal dynamics of microbial planktonic diversity in coastal ecosystems; however, disentangling their effects is challenging because they are always tightly coupled. Shallow coastal lagoons exhibit intense temperature
