Halictus? savenyei

Halictus? savenyei 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 Halictus? savenyei rather than just read about it. In short: Halictus? savenyei is an extinct species of sweat bee possibly in the halictid genus Halictus. The species is solely known from the Early Eocene, Ypresian stage, Coldwater Beds, part of the Princeton Group, in the Quilchena area, Nicola Country, British Columbia, Canada.

Reference excerpt

Halictus? savenyei is an extinct species of sweat bee possibly in the halictid genus Halictus. The species is solely known from the Early Eocene, Ypresian stage, Coldwater Beds, part of the Princeton Group, in the Quilchena area, Nicola Country, British Columbia, Canada.

History and classification Halictus? savenyei is known only from one fossil, the part and counterpart holotype, specimen numbers "Q-0424a" for the part and "Q-0424b" for the counterpart respectively. The specimen is composed of a complete female specimen preserved as a compression fossil on small chips of shale, recovered from outcrops of the Coldwater Beds shales in the Quilchena area by Rene Savenye. The type specimen is currently preserved in the Department of Paleobiology collections housed at Simon Fraser University, located in Burnaby, British Columbia, Canada. H.? savenyei was first studied by Michael S. Engel of the University of Kansas, Lawrence, Kansas, USA and S. Bruce Archibald of the Museum of Comparative Zoology in Cambridge, Massachusetts, USA. Their 2003 type description of the new species was published in the journal The Canadian Entomologist. Engel and Archibald coined the specific epithet savenyei in honor of the late Rene Savenye who found and donated the fossil. At the time of the species description, Halictus? savenyei was the second-oldest bee body fossil described and the only bee described from Canadian fossil deposits.

Description The H.? savenyei type specimen is a fairly well preserved complete adult female preserved with portions of the fore-wings and hind-wings. The specimen is 7.04 millimetres (0.277 in) long with the possibility of alteration in length during fossilization. The sections of forewing which are preserved are approximately 4.8 millimetres (0.19 in) long and show dark brown to black coloration. The presence of a pygidial plate bordered by setae on the fifth metasomal tergum supports the placement into the Halictidae subfamily Halictinae. Placement into the tribe Halictini is based on the lack of a medial cleft in the fifth tergum.

Worked examples

Example 1 — a first encounter with Halictus? savenyei

Start with the simplest possible case. Write down what Halictus? savenyei 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 Halictus? savenyei 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 Halictus? savenyei 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 Halictus? savenyei

In research: Halictus? savenyei 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 Halictus? savenyei 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: Halictus? savenyei is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coldwater Beds, Fossil bee taxa, Fossil taxa described in 2003, so understanding it makes those chapters shorter.
In everyday life: Look for Halictus? savenyei 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.
