Hymenostylium gracillimum

Hymenostylium gracillimum 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 Hymenostylium gracillimum rather than just read about it. In short: Hymenostylium gracillimum is a species of moss in the family Pottiaceae. It is an endangered species found in Austria and Russia.

Key takeaways

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

Reference excerpt

Hymenostylium gracillimum is a species of moss in the family Pottiaceae. It is an endangered species found in Austria and Russia.

Taxonomy and history Gymnostomum gracillimum was described by German botanist Christian Gottfried Daniel Nees von Esenbeck and colleagues in 1823 based on a population growing on a slate rock wall near Hüttau in Salzburg, Austria. In 1846 G. gracillimum was designated a variety of Gymnostomum calcareum by Philipp Bruch and colleagues. Gymnostomum calcareum var. gracile was described by Georg Roth in 1903 based on a specimen collected from Radstädter Tauern Pass, also in Salzburg, Austria. In 1986 Elsa Nyholm and Lars Hedenäs described Gymnostomum boreale from Karelia. These names would all be reduced to synonymy with Hymenostylium gracillimum by Heribert Köckinger and Jan Kučera in 2011.

Distribution and habitat H. gracillimum is known from eight localities: seven in the Austrian Alps and one in Russian Karelia. In Austria, it can be found at elevations of 500–1,300 m (1,600–4,300 ft) above sea level. It grows on moist, shaded rocks, and appears to prefer slate, phyllite and schist substrates.

Worked examples

Example 1 — a first encounter with Hymenostylium gracillimum

Start with the simplest possible case. Write down what Hymenostylium gracillimum 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 Hymenostylium gracillimum 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 Hymenostylium gracillimum 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 Hymenostylium gracillimum

In research: Hymenostylium gracillimum 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 Hymenostylium gracillimum 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: Hymenostylium gracillimum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dicranidae stubs, Flora of Austria, Flora of North European Russia, so understanding it makes those chapters shorter.
In everyday life: Look for Hymenostylium gracillimum 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.
