Testate amoebae are informative about palaeoecological conditions, but the methods generally used for their analyses in lake sediments differ from those used for their analyses in peats, making comparisons difficult. This study examines how filter mesh siz ...
The complex of Dicronorhina Hope taxa without cretaceous marks on head and body (“micans group”) is here diagnosed, discussed and revised. The type species of the genus, Scarabaeus micans Drury, 1773, is identified and re-described. D. johnstoni Waterhouse ...
Invasion success is favoured by the introduction of pre-adapted genotypes. In addition, novel pressures in the introduced range may lead to phenotypic changes related to fitness or competitive ability of introduced plants. Polyploidy appears to be over-rep ...
Precision is a crucial property of noisy circadian oscillators that can be quantified by the quality factor (Q). Until now, deterministic properties of circadian oscillations like the period or amplitude attracted most of the attention while relatively few ...
During mild heat-stress, a native thermolabile polypeptide may partially unfold and transiently expose water-avoiding hydrophobic segments that readily tend to associate into a stable misfolded species, rich in intra-molecular non-native beta-sheet structu ...
Background and Aims: Knowledge on how climate-induced range shifts might affect natural selection is crucial to understand the evolution of species range. Methods: Using historical demographic perspectives gathered from regional-scale phylogeography on the ...
In this paper, we present an approach capable of extracting insights on ecosystem organization from merely occurrence (presence/absence) data. We extrapolate to the collective behavior by encapsulating some simplifying assumptions within a given set of con ...
The induction of a signaling pathway is characterized by transient complex formation and mutual posttranslational modification of proteins. To faithfully capture this combinatorial process in a mathematical model is an important challenge in systems biolog ...
Invasive plant species represent a threat to terrestrial ecosystems, but their effects on the soil biota and the mechanisms involved are not yet well understood. Many invasive species have undergone polyploidisation, leading to the coexistence of various c ...
Dinitrogen fixation by cyanobacteria is of particular importance for the nutrient economy of cold biomes, constituting the main pathway for new N supplies to tundra ecosystems. It is prevalent in cyanobacterial colonies on bryophytes and in obligate associ ...
