Migratory birds may seem to be well equipped to cope with the consequences of climate change, because their trait of seasonal migration is of course already an evolutionary adaptation to temperature fluctuations that characterise the seasons of Earth’s temperate climate … Continue reading →
The numbers of flying insects in nature reserves throughout Germany show a staggering decline. Taken on average over the months of April to October between 1989 and 2016 insect numbers declined 76%. In mid-summer measurements show an even more rapid … Continue reading →
Falling snow flakes are humbling. Not just because of their beauty, but also because of their gentle ability to completely paralyse a developed and overpopulated country with traffic jams, clogged railroad switches and closed runways. But although that (together with … Continue reading →
Percentage of unsuitable sites among those predicted to be occupied.
A modeling study from the European Alps suggests that population declines to be observed during the upcoming decades will probably underestimate the long-term effects of recent climate warming on mountain plants. A European team of ecologists around Stefan Dullinger from the Department of Conservation Biology, Vegetation and Landscape Ecology of the University of Vienna presents a new modeling tool to predict migration of mountain plants which explicitly takes population dynamic processes into account. Their results are published in “Nature Climate Change“.
Drosophila suzukii caught in Spain. Out of 3,000 Drosophilae species only two are damaging to fruit crops. Here is one, invading from Asia to the US and now Europe.
Coming from the Asian continent, Drosophila suzukii has only been in Spain for a short time. Far away from slipping through into the Iberian Peninsula, it accelerated towards the north of Europe where it has already crossed the Alps. Amongst its preferred target are cherries and red fruits but any type of fruit is suitable for it to lay its eggs. This insect is posing a threat to the fruit of more and more European countries.
In climatology development of the average may differ substantially from the extremes – both as a characteristic of the normal distribution – and the possibility of skewness increases. On average the Dutch climate shows a clear warming trend – but … Continue reading →
