Current and Cretaceous-Cenozoic diversification of Angiosperms
Cretaceous-Cenozoic history of angiosperms led to the a certain character of the distribution of taxa of different levels (the number of species and genera in families, species/genera ratio in families, the number of species in the genera). In most cases, these distributions are satisfactorily described by a power law (Pareto distribution). In logarithmic coordinates power function is a straigh...
متن کاملEarly Cretaceous angiosperms and beetle evolution
The Coleoptera (beetles) constitute almost one-fourth of all known life-forms on earth. They are also among the most important pollinators of flowering plants, especially basal angiosperms. Beetle fossils are abundant, almost spanning the entire Early Cretaceous, and thus provide important clues to explore the co-evolutionary processes between beetles and angiosperms. We review the fossil recor...
متن کاملLong-Proboscid Flies as Pollinators of Cretaceous Gymnosperms
The great evolutionary success of angiosperms has traditionally been explained, in part, by the partnership of these plants with insect pollinators. The main approach to understanding the origins of this pervasive relationship has been study of the pollinators of living cycads, gnetaleans, and basal angiosperms. Among the most morphologically specialized living pollinators are diverse, long-pro...
متن کاملEvolutionary Analysis of MIKCc-Type MADS-Box Genes in Gymnosperms and Angiosperms
MIKCc-type MADS-box genes encode transcription factors that control floral organ morphogenesis and flowering time in flowering plants. Here, in order to determine when the subfamilies of MIKCc originated and their early evolutionary trajectory, we sampled and analyzed the genomes and large-scale transcriptomes representing all the orders of gymnosperms and basal angiosperms. Through phylogeneti...
متن کاملPreface to “Linear sequence, classification, synonymy, and bibliography of vascular plants: Lycophytes, ferns, gymnosperms and angiosperms”
Organizing knowledge of the natural world into a system aids communication and helps us to understand better the organisms that surround us and upon which we depend. These classifications are often embedded in cultural and social systems, and in the past such “folk taxonomies” have been absorbed into scientific taxonomy. The basic function of words is that of naming (Lyons 1977), and in the hum...
