The underlying causes of the global decline of wild bees is important to understand because bees are essential for pollination of both crops and …

The conventional wisdom linking high genetic diversity with population viability is increasingly scrutinized, as empirical evidence shows that some species can persist despite low …

The study of deleterious variation, or genetic load, in natural populations has become increasingly important in conservation genomics, particularly with the advent of novel …

In population genetics, making an accurate calling and phasing of genetic variants is crucial, but it is often a non-trivial challenge, especially for non-model …

The magnificent antlers of the deer family Cervidae represent one of the classic examples of evolution of an exaggerated character through sexual selection. Empirical …

Insects are the most species-rich group of organisms on Earth. It has long been suggested that evolution of the wing played a crucial role …

Multiple species of fungi coexist in soil. They constantly engage in warfare for food sources and territory, and have developed different strategies to survive …

Every year long-distance migratory birds fly thousands of kilometres, crossing desserts and seas, when flying back and forth between their breeding and wintering areas. …

The quality of food has large effects on animals' ability to cope with different environmental challenges, such as temperature. In particular, the composition of …

Environmental temperature is a key parameter that can affects both the external and internal morphology of birds’ bodies. However, there are few data that …

Animals constantly process environmental information to carry out routine activities such as locating food, selecting habitat, recognizing mates, finding prey and avoiding predators in …

Male-limit sexual signals are often thought to impact fitness by increasing his attractiveness or competitive abilities. In a colorful and sexually dimorphic group of …

Weather radars “see” more than just weather, they continuously register also biological activity in the air. This has recently been used in many studies …

Many passerines initiate migration soon after sunset and fly until early morning. It is however unclear how this pattern is affected by the large …

Pollinators are key drivers of floral evolution through natural selection on floral traits. Co-flowering plants within a community often share pollinators which can generate …

To navigate purposefully, an animal must align its body orientation with its intended target and adjust its course accordingly. In the insect world, this …

The most well-known life-history trade-off involves the survival cost of reproduction – reproduction (e.g., fertility, number of eggs) is commonly ‘costly’ in terms of …

Much of what we know about the drivers of plant phenotypic divergence and fitness stems from studies that focus on specialized pollination systems. Much …

We have previously found empirical evidence for antagonistic coevolution between the sex chromosomes in Drosophila melanogaster (see Lund-Hansen et al 2021, https://www.pnas.org/doi/full/10.1073/pnas.2003359118) and are …

Birds observed outside their normal distribution range, vagrants, have fascinated bird watchers for more than a century. The causes behind vagrancy are probably many …
