Boris Balinsky
Borys Ivanovych Balinsky (23 September 1905 – 1 September 1997) was a Ukrainian and South African biologist, embryologist, entomologist, professor of Kyiv University and University of the Witwatersrand. Pioneer researcher in the field of experimental embryology, electron microscopy and developmental biology. He was author of popular textbook in embryology ''An Introduction to Embryology''. Balinsky was born 23 September 1905, in Kyiv, Russian Empire (now Ukraine). He was a student of Ivan Schmalhausen and one of the first to experimentally induce organogenesis in amphibian embryos. Balinsky was a full university professor and the deputy director of the Institute of Biology in Kyiv (now I. I. Schmalhausen Institute of Zoology) at 28 years of age. He became a recognized expert in fish and amphibian development. Being a victim of Soviet repressions, he remained under German occupation during World War II and fled to Poznań, Poland and later Munich, Germany. Balinsky briefly wor ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Of South Africa
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
