Predators and scavengers: Polar bears as marine carrion providers

open access: yesOikos, EarlyView.
Scavenging is a foraging strategy widely used across the animal kingdom and apex predators provide a large amount of energy in a food web by provisioning carrion. In the harsh environmental conditions of the Arctic, apex predators such as polar bears Ursus maritimus can provide scavenging opportunities for many species. Carrion can act as a buffer when

Nutritional effects on the expression of cryptic pigmentation in freshwater isopods

open access: yesOikos, EarlyView.
Cryptic pigmentation is a key phenotypic adaptation that helps many benthic invertebrates evade visual predators. However, little is known about whether and how the expression of pigmentation phenotypes that match the habitat background is influenced by the availability of nutritional resources.

Inconsistent effects of P enrichment and predator presence on food‐web dynamics in a bromeliad system

open access: yesOikos, EarlyView.
Food webs consist of trophic interactions of variable strength. However, it remains challenging to predict how changes in environmental conditions, such as nutrient enrichment, can affect these interactions. In this paper, we propose to integrate food web theory with ecological stoichiometry, which predicts how elemental ratios affect trophic ...

Postnatal Growth Patterns and Deviations in Singleton and Twin Infants: A Prospective Cohort Study on Infants Appropriate and Small for Gestational Age

open access: yesPediatric Discovery, EarlyView.
This is a cohort study including 340 infants stratified into small or appropriate for gestational age. We examined their early physical growth characteristics and described the differences in etiology and catch‐up growth patterns between singleton and twin small for gestational age infants.
