A modeling study to shed light on the spatial ecology of Parnassius apollo during the Quaternary glacial cycles and which are the perspective of the species in the near future under a climate change scenario.
Alena Bruce Krejčí's team from the Biology Centre CAS and the Faculty of Science of the University of South Bohemia focused on the permeability of wax cappings. In cooperation with the plant physiologist Jiří Kubásek, they measured the carbon dioxide permeability of brood and honey cappings for the first time.
Among the 24 articles in the summary of the most interesting scientific publications of the December issue of BioOne Vista is the work of the author team from the Institute of Entomology of the Biology Centre of the Czech Academy of Sciences. Their study deals with new isolates of various species of entomopathogenic fungi and their effectiveness against the bulg mite (Rhizoglyphus robini),...
In two new papers published today in Science, researchers from the Royal Botanic Gardens, Kew and partners from over 50 global organisations, Biology Centre CAS included, have undertaken a major review of Madagascar’s extraordinary biodiversity. Bringing together the most up to date resources and using cutting-edge techniques to predict conservation status, the team evaluated the threats...
Peptidic analogs of the juvenile hormone (JH) selectively interfere with development of linden bugs. Newly derived peptidic juvenoids bind and activate the JH receptor of the linden bug at picomolar doses, thus by far surpassing potency of the native linden bug hormone.
The work examines the parallel between the reward system in bees as a social insect and human society.
Some insects survive winter with their body water frozen. In preparation for overwintering, they accumulate mixtures of different small molecules – most often sugars, amino acids and their derivatives, and also proteins, in their hemolymph. Based on in vitro assays and theory, insect physiologists hypothesized that these molecules protect insect enzymes and biological membranes against loss of...
Mayflies are one of the oldest pterygote insects, with relatively rare remnants in sedimentary rocks and fossil resins. The team of scientists from the Czech Republic, Spain, Poland and Germany have presented the first description of the fossil mayfly species using Micro-CT.
A recent study in the prestigious American journal PNAS by Schultheiss and colleagues has refined estimates of how many ants live in the world and how much they weigh. It estimated that they are approximately 2.5 million worker ants for every human, and all of the ants in the world weigh as much as a fifth of the human population on Earth. The study was followed up by a comment in the same...
The loss of biodiversity and species extinction are well-known phenomena of today. However, biodiversity is not only disappearing today but also emerging. This process was demonstrated by scientists from the Biology Centre and their colleagues from Masaryk University in Brno and the University of Prešov in Slovakia. They found out how the evolution of new species is currently in process in the...
