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...

Fish stock discrimination using image analysis

Fish stock discrimination using image analysis

18. 8. 2020.

Fish stocking is one of the most widespread and frequent management strategies in freshwater systems. However, the contribution of stocked fish to the population is seldom investigated, and hence the effectiveness of this strategy is virtually unknown for many populations. Understanding the contribution of stocked fish into the population is crucial because it allows the disentanglement of the...

During recent decades, increasing anthropogenic activities have affected natural ionic composition in most natural global freshwaters.

Endangered common tern seabird nesting in South Bohemia

Endangered common tern seabird nesting in South Bohemia

22. 7. 2020.

The common tern endangered bird has nested on the Lipno artificial lake, being attracted by experimental floating islands that scientists placed on the reservoir in 2017 to increase the species diversity there. Hydrobiologists, from the centre, uncovered the seabirds during their regular check of the islands. They found four nests with six baby birds of the common tern that is on the...

What can the online world teach us about the natural world?

What can the online world teach us about the natural world?

10. 4. 2020.

In today’s world, an increasing amount of our interactions with one another - as well as interactions with our environment - centres around the digital realm. These may be our posts on social media, internet search engine patterns, or visits to different webpages. Although we may often suspect that today’s technology culture may be generally bringing us away from nature, within these vast and...

Invasive species with charisma have it easier

Invasive species with charisma have it easier

8. 4. 2020.

It's the outside that counts: Their charisma has an impact on the introduction and image of alien species and can even hinder their control. An international research team, led by the Biology Centre of the Czech Academy of Sciences and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB), have investigated the influence of charisma on the management of invasive species.

Lake Fish Telemetry Group: an international and multidisciplinary collaboration to push forward the field of fish ecology and behaviour

5. 2. 2020.

Lake Fish Telemetry Group (LFTG), an initiative that brings together research groups involved in lake fish telemetry in Europe to initiate joint multi-lake research activities using combined fish telemetry datasets, is now in its second year.

Chinese Paddlefish confirmed as extinct

Chinese Paddlefish confirmed as extinct

6. 1. 2020.

A new study by researchers from the China, Czech Republic and UK, concluded that the Chinese Paddlefish can now be confirmed as extinct. With its recorded length of up 7 m, the Chinese paddlefish (Psephurus gladius) was one of the largest freshwater fishes in the world. It was one of only two extant species of paddlefishes (the other being the American paddlefish), a relict lineage that have...

Phage-centric ecological interactions in aquatic ecosystems revealed through ultra-deep metagenomics

Phage-centric ecological interactions in aquatic ecosystems revealed through ultra-deep metagenomics

9. 12. 2019.

In aquatic microbial communities, the most abundant players, the viruses, remain unexplored. Some of them can infect and kill bacteria, those viruses are named bacteriophages or simply phages. Phages influence microbial community ecology affecting nutrient cycle.
