Introducing the Citizen Science Apps: SpiderSpotter

Monday, 14 October 2019 18:28

In this blog series we would like to introduce all our apps and give you an overview of the diverse world of Citizen Science and its possibilities.
The SpiderSpotter App was created in cooperation with the University of Ghent, and will be enjoyed by all spider lovers!

The increasingly hot summers of recent years are problematic, not just for us humans - especially in the cities. The concrete and the buildings heat up during the day, and radiate the heat back during the night, causing challenges for all living things. Of course, spiders are also looking for new ways and means to adapt to these new conditions. With the SpiderSpotter app, scientists are trying to figure out how these changes are going to happen.

Colour and nets

Lighter cars heat up less than dark ones - that's a well-known fact. However, this also applies to spiders! Scientists, therefore, expect spiders to adapt to the city's hotter temperatures by becoming brighter over time to prevent overheating.

As food sources are also more scarce in cities than in the countryside, scientists expect to see webs with a smaller mesh size that are more efficient in capturing prey.

Citizen Scientists are an essential part of the SPIN-CITY project. With the SpiderSpotter app, you can photograph the spiders and document their observations. You can enter all information, from the colour and size of the spider to the nature of their webs. The interactive map ensures that the data is accessible by anyone interested.

By studying spiders, their colours, and webs, scientists get not only valuable information on how animals adapt to climate change but also how fast climate change is progressing. Also, with a little bit of luck, they may provide us with some answers on how to better cool our cities in the future.

  • It’s mushroom season here in Austria, which means it’s the perfect time to introduce you to the Mushroom Finder- the SPOTTERON mushroom web app for citizen scientist! The idea behind it is to preserve the knowledge about wild growing mushrooms and toadstools and, above all, to introduce the topic to and engage the younger generation.
