Russian Translation(s) & Details for 'poikilotherm'

English Word: poikilotherm

Key Russian Translations:

• покилотерм [pɐˈkʲiləˌtɛrm] - [Formal, Scientific]
• холоднокровное животное [xɐˈlodnəkrɐvnəjə ʐɨˈvɔtnəjə] - [Common usage, Informal in educational contexts]
• переменнотемпературный организм [pʲɪrʲɪˈmʲɛnnətʲɪmperaturnɨj ˈɔrɡənɪzm] - [Formal, Technical]

Frequency: Low (This term is specialized and primarily used in scientific or academic contexts, not in everyday conversation.)

Difficulty: Advanced (C1-C2, as it involves biological terminology and requires familiarity with Russian scientific language; for "холоднокровное животное," it may be Intermediate, B2, for learners with basic biology knowledge.)

Pronunciation (Russian):

покилотерм: [pɐˈkʲiləˌtɛrm]

холоднокровное животное: [xɐˈlodnəkrɐvnəjə ʐɨˈvɔtnəjə] (Note on холоднокровное животное: The stress falls on the third syllable of "холоднокровное," which can be tricky for English speakers due to the soft consonants; pronounce with a clear "kh" sound as in "loch." Variations may occur in regional dialects.)

переменнотемпературный организм: [pʲɪrʲɪˈmʲɛnnətʲɪmperaturnɨj ˈɔrɡənɪzm] (Note on переменнотемпературный организм: This compound word has multiple syllables; focus on the primary stress on "tem-pera-tur-nyj" to avoid mispronunciation.)

Audio: []

Meanings and Usage:

Primary meaning: An animal whose body temperature varies with the environment (e.g., reptiles, fish).

Translation(s) & Context:

• покилотерм - Used in formal scientific writing or lectures; preferred in biological research contexts.
• холоднокровное животное - Common in general education and casual discussions about biology; implies a broader, less technical understanding.
• переменнотемпературный организм - Applied in advanced ecological or physiological contexts, emphasizing the organism's adaptive mechanisms.

Usage Examples:

• Русский пример: Покилотермные животные, такие как ящерицы, зависят от внешней среды для поддержания температуры тела.

  English translation: Poikilothermic animals, such as lizards, depend on the external environment to maintain their body temperature.

• Русский пример: В отличие от теплокровных млекопитающих, холоднокровные животные не тратят энергию на нагрев тела.

  English translation: Unlike warm-blooded mammals, poikilothermic animals do not expend energy to heat their bodies.

• Русский пример: Учёные изучают, как переменнотемпературные организмы адаптируются к экстремальным климатическим условиям.

  English translation: Scientists study how poikilothermic organisms adapt to extreme climatic conditions.

• Русский пример: Покилотерм часто используется в биологических текстах для описания рептилий и амфибий.

  English translation: Poikilotherm is often used in biological texts to describe reptiles and amphibians.

• Русский пример: Холоднокровное животное, например, змея, может замедлить метаболизм в холодную погоду.

  English translation: A poikilothermic animal, for example, a snake, can slow its metabolism in cold weather.

Russian Forms/Inflections:

"покилотерм" is a masculine noun (as a borrowed term) and follows standard Russian declension patterns for nouns ending in a consonant. It is relatively stable but can inflect based on case and number.

For "холоднокровное животное," it is a phrase where "холоднокровное" is an adjective (neuter in this context) and "животное" is a neuter noun. It follows standard adjective-noun agreement: e.g., Nominative: холоднокровное животное; Genitive: холоднокровного животного.

"переменнотемпературный организм" is invariable in its adjectival form but inflects as a masculine noun for "организм." It does not have irregular changes.

Russian Synonyms/Antonyms:

• Synonyms:
  • холоднокровный (more general, often used interchangeably but implies colder blood specifically)
  • переменнотемпературный (emphasizes temperature variability in scientific contexts)
• Antonyms:
  • гомойотермный (homeothermic, referring to animals with constant body temperature)
  • теплокровный (warm-blooded)

Related Phrases:

• Холоднокровные рептилии - Refers to cold-blooded reptiles, often in discussions of animal adaptation.
• Переменнотемпературная адаптация - Means temperature-variable adaptation, used in ecological studies.
• Покилотермные виды - Describes poikilothermic species, common in biodiversity contexts.

Usage Notes:

In English, "poikilotherm" is a precise biological term, and its Russian equivalents like "покилотерм" are direct borrowings used in formal settings. Choose "холоднокровное животное" for everyday or educational explanations, as it is more accessible. Be mindful of grammatical agreement in Russian sentences; for example, adjectives must match the noun's gender, number, and case. This term is rarely used in casual conversation, so it's best for academic or professional contexts. When selecting among translations, opt for "покилотерм" in scientific writing for accuracy, but "переменнотемпературный организм" if emphasizing physiological aspects.

Common Errors:

• Mistake: Using "покилотерм" as an adjective without proper agreement, e.g., incorrectly saying "покилотерм животное" instead of "покилотермное животное."
  Correct: "Покилотермное животное" – Explanation: In Russian, adjectives must agree with the noun in gender, so ensure it matches the neuter "животное."
• Mistake: Confusing with "теплокровный," leading to misuse in definitions.
  Correct: Use "холоднокровное" for poikilotherms; antonym "теплокровный" is for homeotherms. – Explanation: This error stems from overlapping concepts in biology, so double-check the context.

Cultural Notes:

This term lacks significant cultural connotations, as it is a scientific concept. However, in Russian literature and education, discussions of "холоднокровные животные" often appear in biology textbooks or nature documentaries, reflecting Russia's vast ecosystems where such animals are prevalent, like in Siberian reptiles adapting to extreme cold.
