Is it better to wait or move to get food? Unique experiment tracks pike behaviour in large lakes

Is it better to wait or move to get food? Unique experiment tracks pike behaviour in large lakes

23. 9. 2021.

A new study carried out by scientists from the Institute of Hydrobiology of the BC CAS has focused on the question of how the behavior of aquatic predators will change when aquatic plants are present or absent in lakes.

Binge-watching, baking, and birding – increased interest in garden birds during the first Covid-19 lockdown

Binge-watching, baking, and birding – increased interest in garden birds during the first Covid-19 lockdown

5. 8. 2021.

The lockdowns enacted in many places as a result of the Covid-19 pandemic led to wholesale changes in many societies since early 2020. As many people stayed in their homes, they took part in new activities, or ones that are normally reserved for different periods or locations. Moreover, the forced confinement of many people increased their need for alternate expressions of freedom, space, and...

Diverse effects of accelerating climate change on chemical recovery of alpine lakes from acidic deposition in soil-rich versus scree-rich catchments.

When did the first COVID-19 case arise? Novel analysis suggests much earlier, more rapid spread than confirmed cases imply

When did the first COVID-19 case arise? Novel analysis suggests much earlier, more rapid spread than confirmed cases imply

25. 6. 2021.

Using methods from conservation science, a new analysis suggests that the first case of COVID-19 arose between early October and mid-November, 2019 in China, with the most likely date of origin being November 17. The study was performed by David Roberts and Jeremy Rossman of the University of Kent, U.K., and Ivan Jarić of the Biology Centre, Czech Academy of Sciences.

World’s lakes losing oxygen rapidly as planet warms

World’s lakes losing oxygen rapidly as planet warms

2. 6. 2021.

Oxygen levels in the world’s temperate freshwater lakes are declining rapidly – faster than in the oceans— a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality. Hydrochemist Josef Hejzlar from the Biology Centre CAS was involved in the research analyzing the dataset from the Czech reservoirs and lakes, which showed that in Central Europe,...

Counting the cost of invasive species

Counting the cost of invasive species

31. 3. 2021.

Biological invasions — the introduction and spread of a species outside its native habitat — have resulted in at least US$1.288 trillion (2017 US dollars) in associated costs worldwide between 1970 and 2017, according to a study published online in Nature this week. One of the authors of the study was Ivan Jarić from the Biology Centre, CAS, who was involved in the work on data collection and...

Tracking invasions with digital data

Tracking invasions with digital data

22. 3. 2021.

Large online data sources are increasingly important to understand biological invasions. Emerging fields of conservation culturomics and iEcology have a great potential to inform invasion science and practice through novel insights and knowledge. In a recent publication, an international research team led by the Biology Centre of the Czech Academy of Sciences is looking at the state of the art...

Fish scales as archives of environmental change

Fish scales as archives of environmental change

19. 3. 2021.

Scales have been widely used to determine the age and growth status of fish. As a result, extensive collections of archived fish scales are stored in numerous fisheries agencies, research institutions and museums. Modern scientific methods make it possible to obtain new information from archived biological samples, for example, information on historical environmental conditions, dietary...

Stories of Želivka asp

11. 3. 2021.

This story will take us to the Švihov reservoir on the Želivka river. It is one of the most important dam reservoirs in the Czech Republic, which supplies the majority of the capital city of Prague and its surroundings with raw drinking water. It is less known that this reservoir hosts a very interesting population of Asp or rapacious carp (Leuciscus aspius). This fish is interesting in that it...
