Gesomyrmex pulcher

Gesomyrmex pulcher 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 Gesomyrmex pulcher rather than just read about it. In short: Gesomyrmex pulcher is an extinct species of ant in the subfamily Formicinae known from an Eocene fossil found in Europe. G. pulcher is one of only eight species in the ant genus Gesomyrmex to have been described from fossils found in Europe.

Key takeaways

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

Reference excerpt

Gesomyrmex pulcher is an extinct species of ant in the subfamily Formicinae known from an Eocene fossil found in Europe. G. pulcher is one of only eight species in the ant genus Gesomyrmex to have been described from fossils found in Europe.

History and classification When described, Gesomyrmex pulcher was known from a solitary fossil insect which is a compression-impression fossil preserved in a layer of soft sedimentary rock. Along with other well preserved insect fossils, the G. pulcher specimen was collected from layers of the Lutetian Messel pit World Heritage Site. The formation is composed of brown coals, oil shales, and bituminous shale, which preserved numerous insects, fish, birds, reptiles, and terrestrial mammals as a notable lagerstätten. The area is a preserved maar lake which initially formed approximately 47 million years ago as the result of volcanic explosions. At the time of description, the holotype specimen, number SMF MeI 10999, was preserved in the Senckenberg Research Station Messel fossil collections. The insect was first studied by German entomologists Gennady Dlussky, Torsten Wappler and Sonja Wedmann; their 2009 type description of the new species was published in the electronic journal Zootaxa. The specific epithet pulcher is Latin, meaning "beautiful". The species is one of eight Gesomyrmex species, all of which have been described from European fossils. Three species were described prior to G. pulcher, G. bremii in 1849, G. hoernesi in 1868, and G. miegi in 1937. The remaining four species; G. breviceps, G. curiosus, G. flavescens, and G. germanicus were all described by Dlussky et al in the same 2009 paper as G. pulcher. Six modern Gesomyrmex species have been described so far, all from the tropical regions of Asia, creating a disjunct distribution between the fossil species and the modern species.

Description The Gesomyrmex pulcher specimen is a partially preserved adult queen, which was fossilized with her dorsal side facing upwards and the attached wings folded along her back. The overall length of the queen is approximately 4.8 mm (0.19 in) and the head has an estimated length of 0.95 mm (0.037 in). The antennae are slender in appearance, composed of a scape which extends to the middle of the eye and ten funicular segments which are either shorter than they are wide, or equal in height and width.

Worked examples

Example 1 — a first encounter with Gesomyrmex pulcher

Start with the simplest possible case. Write down what Gesomyrmex pulcher 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 Gesomyrmex pulcher 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 Gesomyrmex pulcher 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 Gesomyrmex pulcher

In research: Gesomyrmex pulcher 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 Gesomyrmex pulcher 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: Gesomyrmex pulcher is common in secondary-school and first-year university syllabi. It links to neighbouring topics Eocene insects of Europe, Formicinae, Fossil ant taxa, so understanding it makes those chapters shorter.
In everyday life: Look for Gesomyrmex pulcher 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.
