Korshikoviella

Korshikoviella is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Korshikoviella rather than just read about it. In short: Korshikoviella is a genus of green algae in the family Characiaceae. The genus name of Korshikoviella is in honour of Aleksandr Arkadievich Korshikov (1889–1942), who was a Ukrainian botanist from the National University of Kharkiv.

Key takeaways

Korshikoviella belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Korshikoviella to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Korshikoviella from memory before moving on to harder problems.

Reference excerpt

Korshikoviella is a genus of green algae in the family Characiaceae. The genus name of Korshikoviella is in honour of Aleksandr Arkadievich Korshikov (1889–1942), who was a Ukrainian botanist from the National University of Kharkiv. It is sometimes spelled as Korschikoviella. The genus was circumscribed by Paul Claude Silva in Taxon vol.8 on page 63 in 1959.

Description Korshikoviella consists of single cells that are epiphytic or epizoic on freshwater algae or crustaceans, or sometimes planktonic. Cells are narrow and spindle-shaped, 25-480 μm long; one end of the cell tapers into a sharp point (or is rounded), while the other end is usually bifurcated (with the exception of K. limnetica) and may be attached to a substrate. Young cells contain a single parietal, laminar chloroplast; as the cell matures, the chloroplast divides, with adult cells having several chloroplasts along the length of the cell. Each chloroplast contains one pyrenoid. Korshikoviella reproduces asexually via zoospores. Zoospores have two flagella, a contractile vacuole, one band-shaped pyrenoid-bearing chloroplast, and an stigma. They are released from the mother cell via a tear in the cell wall. Sexual reproduction has been observed in Korshikoviella michailovskoensis. The male and female gametangia are well-differentiated from the rest of the cell. The species is oogamous, with immobile female gametes and mobile male gametes. A similar genus of algae is Ankyra. Unlike Korshikoviella, it is not epibiontic, and the cell wall of Ankyra is in two separate pieces, while that of Korshikoviella is in one piece.

Habitat and distribution Korshikoviella is found in the coastal areas of lentic ecosystems, and is generally associated with other algae. It is rare and seldom collected, but probably cosmopolitan.

Ecology One species, Korshikoviella gracilipes is an epibiont on Daphnia pulicaria. K. gracilipes appears to have evolutionary adaptations to an epizoic lifestyles, such as timing zoospore and cyst formation with the molting process of Daphnia.

Worked examples

Example 1 — a first encounter with Korshikoviella

Start with the simplest possible case. Write down what Korshikoviella claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Korshikoviella before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Korshikoviella ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Korshikoviella

In research: Korshikoviella appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Korshikoviella in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Korshikoviella is common in secondary-school and first-year university syllabi. It links to neighbouring topics Freshwater algae, Sphaeropleales, Sphaeropleales genera, so understanding it makes those chapters shorter.
In everyday life: Look for Korshikoviella outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
