The brilliant “Father of evolutionary theory” Charles Darwin discovered his findings without knowing about genetics at all. His analysis is based on precise observation and description of wildlife.
When the priest Gregor Mendel lighted on the systematics of heredity in the garden of the Augustinian abbey in Brno at the same time, he limited his investigations to plants. His findings had far-reaching consequences for science and brought him the most justified nickname “Father of genetics”.
But it was only after the verification of his work by animal examples, like his studies on the heredity of sea urchin eggs, that his research was widely accepted in the academic world. In the times of the “Modern synthesis” by J. Huxley in 1942 Mendel’s and Darwin’s visions were merged after many years. Nowadays research of plants and animals is still handled quite separately. A new reference book presents recent research of the special field of evolutionary research and genetics and compares animal and plant examples.
Fast way to new species
One aspect of genetic research deals with polyploid organisms which have more than the usual two chromosome sets in their cells. Polyploidy often results from the fusion of the genetic material of two species (hybridization) or the duplication of the own genome. “Although it might determine dramatic problems polyploidy can lead to complete new species very quickly which do not reproduce with their parents at all or only very limited,” says Dunja Lamatsch from the Research Institute for Limnology of the University of Innsbruck in Mondsee (Austria), one of the editors of the new book. “Especially the combination of the genome increases the variety of genotypes and offers a bunch of new possibilities to evolution: creatures with completely new (“transgressive”) characteristics may arise which do not appear in any principal form; new habitats can be populated.”
Manifold examples for polyploidy
A key point of polyploidy research is focused on the world of plants as polyploidy has played a role in the evolution of 70% of all species. The number of polyploid agricultural crop (e.g. cotton, wheat) is large since some polyploidy plants develop notably large organs (leaves, stem, root, fruits) and moreover show increased vitality and adaptability. This made research in agricultural practice most profitable. Nevertheless also animals show very interesting polyploidy phenomenons, e.g. those which reproduce as natural clones or hybrids of three species.
New reference book in polyploidy
It is no coincidence that the editors of the reference book are situated at limnological research institutes in Germany and Austria: In vertebrates it is most common that fish and amphibians are polyploid. The book “Trends in Polyploidy Research in Animals and Plants” by Matthias Stöck from Leibniz Institute of Freshwater Ecology and Inland Fisheries and Dunja Lamatsch which was recently published by Karger is a milestone in polyploidy. After 30 years eight topics comparing current examples from animals and plants are collated and discussed. Numerous reputable authors from twelve countries contributed to this book.

A unique solar panel design made with a new ceramic material points the way to potentially providing sustainable power cheaper, more efficiently, and requiring less manufacturing time.
It also reaches a four-decade-old goal of discovering a bulk photovoltaic material that can harness energy from visible and infrared light, not just ultraviolet light.
Scaling up this new design from its tablet-size prototype to a full-size solar panel would be a large step toward making solar power affordable compared with ...
Atlantische Flohkrebse pflanzen sich jetzt auch in arktischen Gewässern fort
Biologen des Alfred-Wegener-Institutes, Helmholtz-Zentrum für Polar- und Meeresforschung (AWI), haben zum ersten Mal nachgewiesen, dass sich in den arktischen Gewässern westlich Spitzbergens auch Flohkrebse aus dem wärmeren Atlantik fortpflanzen.
Diese überraschende Entdeckung deute auf einen möglichen Wandel der arktischen Zooplankton-Gemeinschaft hin, berichten die Wissenschaftler und Wissenschaftlerinnen in der Fachzeitschrift Marine Ecology ...
The molecular architecture of three key proteins and their complexes reveals how plants fine-tune their immune response to pathogens
Plants rarely get sick in their natural environment. When the threat of infection arises, a quick decision is made about the necessary countermeasures. The course is set by a protein which forms complexes with its partner proteins for this purpose.

Researchers studying speciation of butterfly orchids on the Azores have been startled to discover that the answer to a long-debated question "Do the islands support one species or two species?" is actually "three species".
Hochstetter's Butterfly-orchid, newly recognized following application of a battery of scientific techniques and reveling in a complex taxonomic history worthy of Sherlock Holmes, is arguably Europe's rarest orchid species. Under threat in its mountain-top retreat, the orchid urgently requires conservation recognition.

Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon's largest impact crater.
Data from the Moon Mineralogy Mapper that flew aboard India's Chandrayaan-1 lunar orbiter shows a diverse mineralogy in the subsurface of the giant South Pole Aitken basin.
The differing mineral signatures could be reflective of the minerals dredged up at the time of the giant impact 4 billion years ago, ...
