The effect of grey wolf (Canis lupus) and human disturbance on the activity of big game species in the Bükk Hills, Hungary

The paper analyzes camera trap data to compare activity overlap between wolves, humans, and big game species in Hungary, finding that human disturbance has a greater impact on game activity than wolf presence.

Publication games: in the web of reciprocity

The paper models how publication cartels can increase productivity but also create conflicts of interest, suggesting the 1/n rule may lead to self-purification in academia.

Seasonal variation of genotypes and reproductive plasticity in a facultative clonal freshwater invertebrate animal (Hydra oligactis) living in a temperate lake

This study examines seasonal genetic and reproductive changes in Hydra oligactis using RAD-Seq, finding no significant genetic change but persistent clonal lineages and genotype-specific sexual reproduction frequency.

Experimental manipulation of body size alters senescence in hydra

This study manipulates body size in Hydra to show that smaller size delays sexual development and increases post-reproductive survival, linking body size to reproduction and senescence independently of growth.

Social groups with diverse personalities mitigate physiological stress in a songbird

This study shows that social groups with diverse personalities improve physiological stress and condition in house sparrows.

Spatio-temporal structure and reproductive success in a rook (Corvus frugilegus) colony

This study examines how breeding timing and nest location affect reproductive success in a rook colony, finding that early nesting and clustering in dense areas improve outcomes.

Demographic causes of adult sex ratio variation and their consequences for parental cooperation

The paper examines how demographic processes affect adult sex ratio variation and its impact on parental cooperation in shorebirds.

Reproductive mode, stem cells and regeneration in a freshwater cnidarian with post-reproductive senescence

This study examines the physiological costs of sexual vs. asexual reproduction in Hydra oligactis, finding that sexual reproduction reduces stem cell pools and regeneration ability.
