Reference ranges provide a powerful tool for diagnostic decision-making in clinical medicine and are enormously valuable for understanding normality in pre-clinical scientific research that uses in vivo models. As yet, there are no published reference ranges for electrocardiography (ECG) in the laboratory mouse. The first mouse-specific reference ranges for the assessment of electrical conduction are reported herein generated...
The foraging ecology of mammalian herbivores is strongly shaped by plant secondary compounds ( PSC s) that defend plants against herbivory. Conventional wisdom holds that gut microbes facilitate the ingestion of toxic plants; however, this notion lacks empirical evidence. We investigated the gut microbiota of desert woodrats ( Neotoma lepida ), some populations of which specialise on highly toxic creosote bush ( Larrea trident...
The bacterial endosymbiont of aphids, Buchnera aphidicola , often provides amino acids to its hosts. Plasmid amplification of leucine ( leuABCD ) and tryptophan ( trpEG ) biosynthesis genes may be a mechanism by which some Buchnera over‐produce these nutrients. We used quantitative polymerase chain reaction to assess the leuABCD / trpEG copy variability within Uroleucon ambrosiae , an aphid with a wide diet breadth and range....
Intracellular symbionts of sharpshooters (Insecta: Hemiptera: Cicadellinae) form a distinct clade with a small genomeNARA Subscribed
Summary The leafhoppers (Insecta: Hemiptera: Cicadellidae) are the most species‐rich group of invertebrates in which intracellular symbionts are usual. Here we present the first molecular characterization of bacteriome‐associates in the leafhoppers, with focus on the subfamily Cicadellinae (sharpshooters). Phylogenetic analyses of 16S rDNA sequences from intracellular symbionts residing in the bacteriomes of five host species...
