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.

Microbial food webs in hypertrophic fishponds: omnivorous ciliate taxa are major protistan bacterivores

Microbial food webs in hypertrophic fishponds: omnivorous ciliate taxa are major protistan bacterivores

22. 11. 2019.

Small bacterivorous protists play a fundamental role in aquatic food webs and their taxonomic classification and ecological traits currently belong to core topics in aquatic microbial ecology. Despite the importance of shallow lakes worldwide, knowledge of microbial components, the base of their food webs, remains scarce. To close this gap, we investigated planktonic microbial food webs, in...

Climate change influences on the dominance hierarchy of crabs

Climate change influences on the dominance hierarchy of crabs

25. 10. 2019.

Climate change is expected to affect the life of many aquatic organisms. While most studies focus on physiological and ecological consequences of the climatic shift, only a few investigates the effects on animal behavior. Ectotherms (animals that cannot regulate their body temperature through endogenous process) probably will have to alter their behaviors to find suitable habitats in changing...

Evolution in action: habitat transition from sediment to the pelagial leads to genome streamlining in Methylophilaceae

Evolution in action: habitat transition from sediment to the pelagial leads to genome streamlining in Methylophilaceae

16. 10. 2019.

Freshwater lakes are numerically dominated by very small microbes that appear perfectly adapted to nutrient poor (oligotrophic) conditions because of efficient resource exploitation in nM concentrations. The genomes of such oligotrophs are characterized by being very small (streamlined, <1.5 Mbp) with highly conserved core genomes and few pseudogenes, high coding densities, reduced numbers...

Šimek, K. and Sirová, D. 2019: Fluorescently Labeled Bacteria as a Tracer to Reveal Novel Pathways of Organic Carbon Flow in Aquatic Ecosystems. J. Vis. Exp. (151), e59903, doi:10.3791/59903 Elucidating trophic interactions, such as predation and its effects, is a frequent task for many researchers in ecology. The study of microbial communities has many limitations, and...
