...Yanira Jiménez-Padilla; Babafemi Adewusi; Marc-André Lachance; Brent J. Sinclair ABSTRACT Insect guts house a complex community of microbes that affect host physiology, performance and behavior. Gut microbiome research has largely focused on bacteria–host symbioses and paid less attention to other...

..., but it is unknown whether the leak of the gut microbiome is a possible immune trigger in the cold. We developed a novel feeding protocol to load the gut of locusts ( Locusta migratoria ) with fluorescent bacteria before exposing them to −2°C for up to 48 h. No bacteria were recovered from the hemolymph of cold...

..., (2) microbiome and immune function and (3) sickness behaviors. By building new bridges among these fields, and strengthening existing ones, a truly integrative approach to understanding the role of host immunity on individual and community fitness is within our grasp. Summary: A discussion...

...-associated microbial communities contribute significantly to the response of ectotherms to environmental warming. However, several unanswered questions about these relationships remain before accurate predictions can be made regarding the microbiome's influence on host ecology and evolution under climate...

Within the HR and control groups, replicate lines had unique microbiomes based on unweighted UniFrac beta diversity, indicating random genetic drift and/or multiple adaptive responses to selection. * Author for correspondence ( [email protected] ) Competing...

Lattin ABSTRACT There are complex interactions between an organism's microbiome and its response to stressors, often referred to as the ‘gut...

... aminotransferases (ALT; AST), is found in teleost fish. Conservation of these enzymes across bacterial phyla suggests that the GIT microbiome could also contribute to ammonia detoxification by providing supplemental activity. Hence, the GIT microbiome, enzyme activities and ammonia detoxification were investigated...

Integration of microbiomes into comparative physiology...

We also tested attraction to two bacteria species, Lactobacillus brevis , which we cultured from larvae in our lab, and L. plantarum , a common constituent of fruit flies' microbiome in other laboratory populations and in wild fruit flies. Neither larvae nor adults showed attraction to axenic...
