Genetic potential for aerobic respiration and denitrification in globally distributed respiratory endosymbionts

The paper identifies four new respiratory endosymbiont genomes, revealing their global distribution and ability to perform both aerobic and anaerobic respiration.

Genome streamlining in CPR bacteria transitioning from soil to groundwater

The paper examines genomic changes in CPR bacteria transitioning from soil to groundwater, finding differences in genome size, replication rate, and gene content.

Rates of primary production in groundwater rival those in oligotrophic marine systems

The paper measures carbon fixation rates in groundwater and finds they rival those in oligotrophic marine systems.

The economical lifestyle of CPR bacteria in groundwater allows little preference for environmental drivers

This study investigates Patescibacteria in groundwater, finding they have minimal metabolic pathways and show little adaptation to environmental drivers, suggesting an economical lifestyle with broad host interactions.

Bolstering fitness via opportunistic CO2 fixation: mixotroph dominance in modern groundwater

The paper uses stable isotope cluster analysis to show mixotrophs, not obligate chemolithoautotrophs, dominate carbon cycling in groundwater by opportunistically using both organic and inorganic carbon sources.

Biology and rearing of the cogongrass gall midge, Orseolia javanica Kieffer & Docters van Leeuwen-Reijnvaan (Diptera: Cecidomyiidae)

This study describes the biology of the cogongrass gall midge and develops a rearing method, finding it completes its life cycle in 12-38 days with specific developmental periods.

Inclusion of Oxford Nanopore long reads improves all microbial and phage metagenome-assembled genomes from a complex aquifer system

This study shows that combining Oxford Nanopore long reads with Illumina sequencing improves the quality and quantity of microbial and phage genomes assembled from groundwater metagenomes.

Defining the seafloor microbiome of the Gulf of Mexico and its response to oil perturbation

The paper characterizes the seafloor microbiome in the Gulf of Mexico, showing it is consistent with depth and sediment stratification, and that DWH-impacted sites had recovered after two years.
