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

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...

Neanderthal and early modern human stone tool culture co-existed for over 100,000 years

Neanderthal and early modern human stone tool culture co-existed for over 100,000 years

4. 3. 2021.

Research from the University of Kent's School of Anthropology and Conservation has discovered that one of the earliest stone tool cultures, known as the Acheulean, likely persisted for tens of thousands of years longer than previously thought.

Microbial drama in four acts: How small waterbodies defy the storms and help the landscapes to overcome consequences

Microbial drama in four acts: How small waterbodies defy the storms and help the landscapes to overcome consequences

8. 2. 2021.

An international research team led by the Institute of Hydrobiology recorded and characterized the response of an entire pond plankton community to heavy rain events. This unique and very detailed survey showed that small waterbodies are able to defy storms and are amazingly resilient mainly thanks to microorganisms.

Emerging digital tools for marine and freshwater conservation

Emerging digital tools for marine and freshwater conservation

29. 10. 2020.

The digital revolution in the age of big data is creating new research opportunities. Approaches such as culturomics and iEcology promise to provide huge benefits and novel sources of information for ecological research, and conservation management and policy. In a recent publication, an international research team led by the Biology Centre of the Czech Academy of Sciences is looking at the...
