Rapid evolution may help species adapt to climate change and competition
A study shows that a fruit fly species can adapt rapidly to an invader and this evolutionary change can affect how they deal with a stressful climate. Over a few months, the naturalized species adapted to the invasive species' presence. This affected how the flies adapted to cold weather. The flies exposed to invasive species evolved in the fall to be larger, lay fewer eggs and develop faster than flies that hadn't been exposed. (2021-02-22)

Future ocean warming boosts tropical rainfall extremes
Climate models predict that the difference between El Niño and La Niña related tropical rainfall will increase over the next 80 years, even though the temperature difference between El Niño and La Niña may change only very little in response to global warming. A new study uncovers the reasons for this surprising fact. (2021-02-22)

Plant responses to climate are lagged
Plant responses to climate drivers such as temperature and precipitation may become visible only years after the actual climate event. This is a key result of new research led by the German Centre of Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz Centre for Environmental Research (UFZ) published in Global Change Biology. The results indicate that climate drivers may have different effects on the survivorship, growth and reproduction of plant species than suggested by earlier studies. (2021-02-22)

Potential regional declines in species richness of tomato pollinators under climate
About 70% of the world's main crops depend on insect pollination. Climate change is already affecting the abundance and distribution of insects, which could cause geographical mismatches between crops and their pollinators. Crops that rely primarily on wild pollinators (e.g., crops that cannot be effectively pollinated by commercial colonies of honey bees) could be particularly in jeopardy. (2021-02-22)
