Museum scientists: Prepare for next pandemic now by preserving animal specimens in natural history
It's been more than a year since the first cases were identified in China, yet the exact origins of the COVID-19 pandemic remain a mystery. Though strong evidence suggests that the responsible coronavirus originated in bats, how and when it crossed from wildlife into humans is unknown.

A bucket of water can reveal climate change impacts on marine life in the Arctic
Climate change prompts many important questions, not least how it affects animals and plants: Do they adapts, gradually migrate to different areas or become extinct? And what is the role played by human activities? This applies not least to Greenland and the rest of the Artic, which are expected to face the greatest effects of climate changes.

Study of flowers with two types of anthers solves mystery that baffled Darwin
Most flowering plants depend on pollinators such as bees to transfer pollen from the male anthers of one flower to the female stigma of another flower, enabling fertilization and the production of fruits and seeds.

How does distance and density dependence vary across life stages of plants?

However, there remains significant debate over the generality and magnitude of J-C effects, especially its role in shaping macro-scale diversity patterns.

Studien bygger på en kartläggning av drygt 500 svenska kvinnors matvanor och förekomsten av allergi hos deras barn vid ett års ålder. – Vi har konstaterat att mammor till friska ettåringar konsumerade mer komjölk under amningen
