Southeastern dwarf salamander

Southeastern dwarf salamander 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 Southeastern dwarf salamander rather than just read about it. In short: The southeastern dwarf salamander (Eurycea quadridigitata), formerly known as the dwarf salamander, is a species of salamander native to the southern United States, ranging primarily from southern North Carolina south to northern Florida, with some populations from southwestern Alabama to eastern Louisiana. Some sources refer to it as the four-fingered manculus, dwarf four-toed salamander, or the Florida dwarf salam…

Key takeaways

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

Reference excerpt

The southeastern dwarf salamander (Eurycea quadridigitata), formerly known as the dwarf salamander, is a species of salamander native to the southern United States, ranging primarily from southern North Carolina south to northern Florida, with some populations from southwestern Alabama to eastern Louisiana. Some sources refer to it as the four-fingered manculus, dwarf four-toed salamander, or the Florida dwarf salamander.

Taxonomy A review of E. quadridigitata published in 2017 identified five cryptic species within E. quadridigitata based on molecular evidence.

Eurycea chamberlaini Harrison and Guttman, 2003: North Carolina and interior areas of South Carolina Eurycea sphagnicola Wray, Means, and Steppan, 2017: Southern Mississippi, Alabama, and far western Florida panhandle Eurycea hillisi Wray, Means, and Steppan, 2017: interior regions of Alabama and Georgia Eurycea paludicola (Mittleman, 1947): Louisiana, Texas and Arkansas Eurycea quadridigitata sensu stricto (Holbrook, 1842): North Carolina south to Florida, west to Louisiana

Description The southeastern dwarf salamander grows from 2.0 to 3.5 inches in length. It has a slender body and a long tail. It is typically yellow-brown in color with darker brown blotching and dark stripes down each side, but the pattern and coloration can vary widely. The epithet quadridigitata is to denote that each of its feet has four toes.

Behavior The southeastern dwarf salamander prefers habitats of swampy pine woods. It is nocturnal and spends most of its time under leaf litter or forest floor debris. Breeding occurs in the fall, with 12 to 48 eggs being laid singly or in small clutches attached to submerged debris in shallow, slow moving or still water.

Worked examples

Example 1 — a first encounter with Southeastern dwarf salamander

Start with the simplest possible case. Write down what Southeastern dwarf salamander 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 Southeastern dwarf salamander 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 Southeastern dwarf salamander 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 Southeastern dwarf salamander

In research: Southeastern dwarf salamander 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 Southeastern dwarf salamander 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: Southeastern dwarf salamander is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amphibians described in 1842, Endemic amphibians of the United States, Eurycea, so understanding it makes those chapters shorter.
In everyday life: Look for Southeastern dwarf salamander 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.
