The Effect of Density-Dependent Phase on the Locust Gut Bacterial Composition

Frontiers in Microbiology, 2019
The desert locust demonstrates density-dependent phase polyphenism: For extended periods it appears in a non-aggregating, non-migrating phenotype, known as the solitary phase. When circumstances change, solitary individuals may aggregate and transform to

Divide and shape: an endosymbiont in action [PDF]

Planta, 2012
The endosymbiotic evolution of the plastid within the host cell required development of a mechanism for efficient division of the plastid. Whilst a model for the mechanism of chloroplast division has been constructed, little is known of how other types of plastids divide, especially the proplastid, the progenitor of all plastid types in the cell.

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

Coordination of host and endosymbiont gene expression governs endosymbiont growth and elimination in the cereal weevilSitophilusspp

Background: Insects living in nutritionally poor environments often establish long-term relationships with intracellular bacteria that supplement their diets and improve their adaptive and invasive powers.

Comparative Endosymbiont Community Structures of Nonviruliferous and Rice Stripe Virus-Viruliferous Laodelphax striatellus (Hemiptera: Delphacidae) in Korea

Viruses
Insects and their bacterial endosymbionts form intricate ecological relationships, yet their role in host–pathogen interactions are not fully elucidated.

Water mass dynamics drive nitrogen fixation rates and diazotroph community composition in the coastal ocean

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Although significant N2 fixation rates (NFRs) have been observed throughout mid‐Atlantic coastal waters, studies have been limited in their temporal coverage, and the methods used to detect nitrogen fixers (diazotrophs) and their findings have varied.

Gut Microbiome Diversity, Functional Potential, and Ecological Relevance of Hottentotta tamulus

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Long‐read 16S sequencing uncovers the gut microbiome of H. tamulus. A highly conserved and low‐diversity bacterial community dominates the gut fauna. Bacillus and Mycoplasma lineages emerge as predominant candidate endosymbionts. Exploratory profiles reveal potential sex‐specific trends in microbial abundance.

Experimental uncoupling of hosts and endosymbionts

mBio
ABSTRACT Many organisms harbor heritable bacterial symbionts that offer context-specific benefits to their hosts. In some of these symbioses, symbionts live inside host cells as endosymbionts. Studying the biology of endosymbiosis is challenging because it is hard to independently cultivate hosts and ...

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, Volume 2026, Issue 10, October 2026.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...
