Trait-specific dispersal of bacteria in heterogeneous porous environments: from pore to porous medium scale

Tom Ian Battin, Hannes Markus Peter, David Scheidweiler, Filippo Miele

The dispersal of organisms controls the structure and dynamics of populations and communities, and can regulate ecosystem functioning. Predicting dispersal patterns across scales is important to understand microbial life in heterogeneous porous environment ...

Microbial life in porous systems

David Scheidweiler

Microbial life in porous systems dominates the functioning of numerous ecosystems, ranging from stream sediments to soils. While these environments are characterized by structures that vary spatially over orders of magnitude, the traditional research focus ...

Sexual selection shapes development and maturation rates in Drosophila

Laurent Keller, Brian Dennis Hollis

Explanations for the evolution of delayed maturity usually invoke trade-offs mediated by growth, but processes of reproductive maturation continue long after growth has ceased. Here, we tested whether sexual selection shapes the rate of posteclosion matura ...

Mutations in the polyglutamylase geneTTLL5, expressed in photoreceptor cells and spermatozoa, are associated with cone-rod degeneration and reduced male fertility

Hereditary retinal degenerations encompass a group of genetic diseases characterized by extreme clinical variability. Following next-generation sequencing and autozygome-based screening of patients presenting with a peculiar, recessive form of cone-dominat ...

Effects of ploidy and sex-locus genotype on gene expression patterns in the fire ant Solenopsis invicta

Chitsanu Khurewathanakul, Laurent Keller, Oksana Riba Grognuz

Males in many animal species differ greatly from females in morphology, physiology and behaviour. Ants, bees and wasps have a haplodiploid mechanism of sex determination whereby unfertilized eggs become males while fertilized eggs become females. However, ...

Taxonomic characterisation of Pseudomonas strain L48 and formal proposal of Pseudomonas entomophila sp nov

Bruno Lemaitre

An entomopathogenic, Gram-negative bacterium isolated from a female specimen of the fruit fly Drosophila melanogaster was taxonomically characterised. Strain L48(T) was strictly aerobic, non-fermentative, oxidase and catalase positive, rod-shaped, and moti ...

Malaria parasites form filamentous cell-to-cell connections during reproduction in the mosquito midgut

Physical contact is important for the interaction between animal cells, but it can represent a major challenge for protists like malaria parasites. Recently, novel filamentous cell-cell contacts have been identified in different types of eukaryotic cells a ...

Quantitative Morphometrical Characterization of Human Pronuclear Zygotes

Michaël Unser, Philippe Thévenaz

BACKGROUND: Identification of embryos with high implantation potential remains a challenge in in vitro fertilization (IVF). Subjective pronuclear (PN) zygote scoring systems have been developed for that purpose. The aim of this work was to provide a softwa ...
