Vertical migration is a geographically and taxonomically widespread behaviour among
zooplankton that spans across diel and seasonal timescales. The shorter‐term diel vertical …

Knowledge of species composition and their interactions, in the form of interaction networks,
is required to understand processes sha** their distribution over time and space. As such …

Optimal foraging theory predicts that predators are selective when faced with abundant prey,
but become less picky when prey gets sparse. Insectivorous bats in temperate regions are …

Ecological research is often hampered by the inability to quantify animal diets. Diet
composition can be tracked through DNA metabarcoding of fecal samples, but whether …

To associate specimens identified by molecular characters to other biological knowledge,
we need reference sequences annotated by Linnaean taxonomy. In this study, we (1) report …

Diets play a key role in understanding trophic interactions. Knowing the actual structure of
food webs contributes greatly to our understanding of biodiversity and ecosystem …

Differences in diet can explain resource partitioning in apparently similar, sympatric species.
Here, we analyzed 1,252 fecal drop**s from five species (Eptesicus nilssonii, Myotis …

Tundra-breeding birds face diverse conservation challenges, from accelerated rates of Arctic
climate change to threats associated with highly migratory life histories. Here we summarise …

The ecological consequences of climate change have been recognized in numerous
species, with perhaps phenology being the most well‐documented change. Phenological …

By depicting who eats whom, food webs offer descriptions of how grou**s in nature
(typically species or populations) are linked to each other. For asking questions on how food …
