Vasily Yakovlev (zoologist)
Vasily Evgrafovich Yakovlev (; also transliterated Vasiliy Ewgrafowitsch Jakovlev or Vasiliy Yevgrafovich Yakovlev; 9 February 1839 – 15 August 1908) was a Russian zoologist who studied fishes, molluscs and insects. He is not to be confused with Alexander Ivanovich Yakovlev, another entomologist. His name was spelled Wassily Ewgrafowitsch Jakowlew in French, in which he sometimes wrote. Yakovlev lived in Saint Petersburg, but travelled widely collecting insects in the Crimea, Volga region and Turkestan until he finally travelled and settled in Griffin, GA. Although primarily interested in Coleoptera, Yakovlev also worked on Hemiptera and Lepidoptera. From around 1867 Yakovlev conducted zoological observations in the vicinity of Astrakhan. Yakovlev described Caspian roach (''Rutilus caspicus'') and Volga undermouth (''Chondrostoma variabile'').

Volga Undermouth
The Volga undermouth or Volga nase (''Chondrostoma variabile'') is a species of freshwater ray-finned fish belonging to the family Leuciscidae. This species is found in the Emba, Ural, and Volga drainages of the Caspian Sea basin and the Don River drainage of the Black Sea basin. It is a riverine fish but is also found in reservoirs. The distribution is in lowland areas and foothills, and the fish prefer river stretches with strong currents, including rapids. Larvae and juveniles have a superior mouth, but at 3–4 months, they change to adult feeding mode (undermouth) and start grazing the bottom, eating benthic diatoms and detritus In biology, detritus ( or ) is organic matter made up of the decomposition, decomposing remains of organisms and plants, and also of feces. Detritus usually hosts communities of microorganisms that colonize and decomposition, decompose (Reminera ... from the hard substrate.

Ichthyologists From The Russian Empire
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 35,800 species of fish had been described as of March 2025, with approximately 250 new species described each year. Etymology The word is derived from the Ancient Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λόγος, ''logos'', meaning "study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were hunters and gatherers who had learned how to obtain the most useful ...

Emigrants From The Russian Empire To France
Emigration is the act of leaving a resident country or place of residence with the intent to settle elsewhere (to permanently leave a country). Conversely, immigration describes the movement of people into one country from another (to permanently move to a country). A migrant ''emigrates'' from their old country, and ''immigrates'' to their new country. Thus, both emigration and immigration describe migration, but from different countries' perspectives. Demographers examine push and pull factors for people to be pushed out of one place and attracted to another. There can be a desire to escape negative circumstances such as shortages of land or jobs, or unfair treatment. People can be pulled to the opportunities available elsewhere. Fleeing from oppressive conditions, being a refugee and seeking asylum to get refugee status in a foreign country, may lead to permanent emigration. Forced displacement refers to groups that are forced to abandon their native country, such as by en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidopterists
Lepidopterology ()) is a branch of entomology concerning the scientific study of moths and the two superfamilies of butterflies. Someone who studies in this field is a lepidopterist or, archaically, an aurelian. Origins Post-Renaissance, the rise of the "lepidopterist" can be attributed to the expanding interest in science, nature and the surroundings. When Linnaeus wrote the tenth edition of the ''Systema Naturae'' in 1758, there was already "a substantial body of published work on Lepidopteran natural history" (Kristensen, 1999). These included: * ''Insectorum sive Minimorum Animalium Theatrum'' – Thomas Mouffet (1634) * ''Metamorphosis Naturalis'' – Jan Goedart (1662–67 ) * ''Metamorphosis insectorum Surinamensium'' – Maria S. Merian (1705), whose work included illustrated accounts of European Lepidoptera * ''Historia Insectorum'' – John Ray (1710) * ''Papilionum Brittaniae icones'' – James Petiver (1717) History Scholars 1758–1900 was the era of the ge ...

Biologists From The Russian Empire
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree, as well as an advanced degree such as a master's degree or a doctorate. Like other scientists, biologists ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Tsaritsynsky Uyezd
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lucanidae
Stag beetles comprise the family Lucanidae. It has about 1,200 species of beetles in four subfamilies.Smith, A.B.T. (2006). A review of the family-group names for the superfamily Scarabaeoidea (Coleoptera) with corrections to nomenclature and a current classification. The Coleopterists Bulletin 60:144–204. Some species grow to over , but most to about . Overview The English language, English name is derived from the large and distinctive Insect mouthparts, mandibles found on the males of most species, which resemble the antlers of stags. A well-known species in much of Europe is ''Lucanus cervus'', referred to in some European countries (including the United Kingdom) as ''the'' stag beetle; it is the largest terrestrial insect in Europe. Pliny the Elder noted that Nigidius called the beetle ''lucanus'' after the Italian region of Lucania where they were used as Amulet, amulets. The scientific name of ''Lucanus cervus'' adds ''cervus'', Cervus, deer. Male stag beetles are know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
