Genetic Codes with No Dedicated Stop Codon: Context-Dependent Translation Termination
Evidence is provided, based on ribosomal profiling and “stop” codon depletion shortly before coding sequence ends, that mRNA 3′ ends may contribute to distinguishing stop from sense in a context- dependent manner and it is proposed that such context-dependent termination/readthrough suppression near transcript ends enables genetic code evolution.

Effects of Habitat Quality and Seasonality on Ranging Patterns of Collared Brown Lemur (Eulemur collaris) in Littoral Forest Fragments
Degraded forest habitats typically show low fruit availability and scattered fruit tree distribution. This has been shown to force frugivorous primates either to move further in search of food,Expand
Habitat Degradation and Seasonality Affect Physiological Stress Levels of Eulemur collaris in Littoral Forest Fragments
Compared fecal glucocorticoid metabolite levels, a measure of physiological stress and potential early indicator of population health, between groups of collared brown lemurs living in a degraded forest fragment and groups occurring in a more preserved area, it is shown that habitat degradation has additive effects to the challenges found in the natural habitat.

Ecological and Anthropogenic Correlates of Activity Patterns in Eulemur
Seasonality, proportions of leaves in the diet, and group size were all found to be significant predictors of the proportion of diurnal activity, and overall anthropogenic disturbance emerged as a negative predictor of diurnality. Expand
“Candidatus Gortzia shahrazadis”, a Novel Endosymbiont of Paramecium multimicronucleatum and a Revision of the Biogeographical Distribution of Holospora-Like Bacteria
A novel species belonging to the “Ca. Gortzia” genus, detected in P. multimicronucleatum, a ciliate for which infection by an HLB has not been reported, discovered in India is described. Expand
Antibiotic treatment of the hard tick Ixodes ricinus: Influence on Midichloria mitochondrii load following blood meal.
An antibiotic treatment on Ixodes ricinus individuals did not allow to eliminate the symbiont population from the host tick, however it allowed to reduce the multiplication that occurs after the larval blood meal, a major step in the understanding of the impact of this bacterium on ticks. Expand
Morphology, ultrastructure, genomics, and phylogeny of Euplotes vanleeuwenhoeki sp. nov. and its ultra-reduced endosymbiont “Candidatus Pinguicoccus supinus” sp. nov.
A new approach to modern taxonomy is proposed, consisting in the inclusion of novel descriptors in the presence of associated microorganisms in the organism characterization, to provide a deeper comprehension of the evolutionary/ecological dimensions of organisms since their very first description.

Molecular evidence for a bacterium of the family Midichloriaceae (order Rickettsiales) in skin and organs of the rainbow trout Oncorhynchus mykiss (Walbaum) affected by red mark syndrome.
Red mark syndrome (RMS) is a chronic skin dis-ease of unknown aetiology affecting farmed rain-bow trout Oncorhynchus mykiss in Europe and can thus cause important economic losses, due to down-grading of the product. Expand
Ciliate communities and hidden biodiversity in freshwater biotopes of the Pistoia province (Tuscany, Italy).
This survey of freshwater systems of the Pistoia province (Tuscany, Italy) provides the first insights into the ciliate fauna of this area, and supplies the first molecular data on well-known taxa such as Linostomella and Disematostoma. Expand
Midichloria mitochondrii, endosymbiont of Ixodes ricinus: evidence for the transmission to the vertebrate host during the tick blood meal.
It is indicated that transmission of the bacterium occurs even at low bacterial loads, and that antibody response against M. mitochondrii antigens begins within one week post-infestation with wild I. ricinus ticks, but surprisingly also in those infested with lab ticks, albeit at later time points.
