Less is more: Antibiotics at the beginning of life
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-27)Antibiotic exposure at the beginning of life can lead to increased antimicrobial resistance and perturbations of the developing microbiome. Early-life microbiome disruption increases the risks of developing chronic diseases later in life. Fear of missing evolving neonatal sepsis is the key driver for antibiotic overtreatment early in life. Bias (a systemic deviation towards overtreatment) and noise ... -

The paradox of searching efficiency or why are violent population cycles so uncommon in terrestrial ecosystem
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-19)The searching efficiency of predators depends on the balance between the adaptations of the predator and the counter-adaptations of the prey. In this evolutionary race, the prey should normally have the upper hand, as it can perform tradeoffs between efficiency in resource use and ability to avoid predators. In terrestrial predator–herbivore systems, however, the huge difference in food quality ... -
