Parent-specific transgenerational immune priming enhances offspring defense - unless heat-stress negates it all

This study shows that parental transgenerational immune priming benefits offspring immunity but is negated by heat-stress, increasing vulnerability to pathogens.

Surviving on limited resources: effects of caloric restriction on growth, gene expression and gut microbiota in a species with male pregnancy (Hippocampus erectus).

This study examines how caloric restriction affects growth, gene expression, and gut microbiota in male-pregnant seahorses, revealing sex-specific resource allocation strategies during reproduction.

Sexual antagonism and sex determination in three syngnathid species alongside male pregnancy gradient and varying sex roles.

This study investigates the link between sexual antagonism and sex determination in three syngnathid species, finding that sex roles and mate competition drive sexual antagonism rather than male pregnancy.

The effect of parental age on the quantity and quality of offspring in Syngnathus typhle, a species with male pregnancy.

This study examines how parental age affects offspring quantity and quality in Syngnathus typhle, showing older parents produce more and larger offspring, with gene expression patterns strongly influenced by paternal age.

Navigating sex and sex roles: deciphering sex-biased gene expression in a species with sex-role reversal (Syngnathus typhle)

The paper examines sex-biased gene expression in Syngnathus typhle, a sex-role reversed species, revealing gene associations with sex roles and biological sex across life stages.

COMPLETE GENOME SEQUENCE OF VIBRIO SYNGNATHI SP. NOV., A FISH PATHOGEN, ISOLATED FROM THE KIEL FJORD

The paper describes the isolation and genome sequencing of a new Vibrio species, Vibrio syngnathi, from a fish pathogen, highlighting its phenotypic features and genomic characteristics.

Slow release of a synthetic auxin induces formation of adventitious roots in recalcitrant woody plants.

This study identifies a synthetic auxin conjugate that enhances adventitious root formation in recalcitrant woody plants through slow auxin release.

The source of microbial transmission influences niche colonization and microbiome development

The study investigates how microbial transmission routes (maternal, paternal, and horizontal) influence microbiome development in pipefish juveniles using 16S rRNA sequencing.

SUB-OPTIMAL ENVIRONMENTAL CONDITIONS PROLONG PHAGE EPIDEMICS IN BACTERIAL POPULATIONS

The paper shows that suboptimal environmental conditions slow phage resistance evolution in bacteria, prolonging phage epidemics and potentially increasing the persistence of virulent phages.

Higher phage virulence accelerates the evolution of host resistance

The paper experiments with phage virulence and shows that higher virulence accelerates host resistance evolution, leading to faster phage extinction.

Pipefish locally adapted to low salinity in the Baltic Sea retain phenotypic plasticity to cope with ancestral salinity levels.

ABCB-mediated auxin transport in outer root tissues regulates lateral root spacing in Arabidopsis

The paper identifies five ABCB transporters that regulate lateral root spacing in Arabidopsis by modulating auxin oscillation amplitude in outer root tissues.

Parental investment and immune dynamics in sex-role reversed pipefishes

The paper investigates how parental investment affects immune dynamics in male pipefishes with varying paternal care intensities, finding a resource-allocation trade-off between pregnancy and immune defense.

Consequences of combining sex-specific life-history traits

The paper develops a theoretical framework to combine sex-specific life-history traits and calculates lifetime reproductive success, revealing biases in adult sex ratio due to resource allocation trade-offs.
