Analysis of contemporary evolution can provide important insights into the pattern and rate of phenotypic evolution. Support your prediction with evidence from the virtual lab. The Stickleback Fish - A Story of Modern Evolution. 1.
Paper Stickleback Sampling Abstract Does the lateral plate trait in a population of stickleback fish change over time? Which lake is located between Bear Paw Lake and Frog Lake just to the north?
... 2 groups of 3-spined stickleback. Thus Loberg’s native freshwater stickleback population was exterminated. Summarize what happened to the fish in Loberg Lake, include an explanation for WHY it happened. stickleback were sampled in the Matanuska-Susitna Valley; and C, sampling sites (A–E) and isobaths (m) within Loberg Lake. studies on contemporary evolution.
Search. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Between 1992 and It has long been a subject of scientific study for many reasons. Start studying Evolution Quiz #2. 3. Create. evolution. Consider that stickleback evolution has followed similar patterns in other lakes across the globe. Why did they poison Loberg Lake. This worksheet is modified from the student worksheet provided by HHMI.
Prator Lake. Habitat conditions are Loberg Stickleback. In 1982 the Alaska Department of Fish and Game poisoned all the fish in Loberg Lake to improve the lake for recreational fishing (i.e. as preparation for restocking the lake with salmon and trout). 6. A fully armored stickleback from the ocean near Loberg Lake (top), and a low-armored stickleback taken from Loberg Lake in 1994 (bottom). To complete this activity students will need a computer with an internet connection and headphones to access videos. Define "model organism."
6. 5. The three-spined stickleback (Gasterosteus aculeatus) is a fish native to most inland coastal waters north of 30°N. The threespine stickleback population in Loberg Lake was exterminated in 1982, and a new population was founded between 1983 and 1989 by anadromous stickleback. How did ancestral populations of ocean-dwelling fish come to live in freshwater lakes? Dr. David Kingsley describes the stickleback lifestyle and how it has led to the evolution of different body forms in a variety of habitats. Support your prediction with evidence from the virtual lab. The body shape of the Loberg Lake population resembled that of anadromous populations in 1990, although it had diverged markedly by 1992. What is the purpose of the spines? 7. 7. 3. stickleback fish. Simulation Info; Download simulation … Individually or in pairs, students collect a random sample of paper stickleback fish from Loberg Lake and plot them by lateral plate number on a bar graph. Is the trait variable among individuals in the population? This activity uses a virtual lab created by HHMI Biointeractive. Fully-armored and low-armored. Stickleback Evolution Lab-- Go to: biol.co/stickfish Introduction: 2.
4. Make a prediction about what would happen in an isolated lake with few predators if humans introduced predatory fish like trout. Make a prediction about what would happen in an isolated lake with few predators if humans introduced predatory fish like trout. Consider that stickleback evolution has followed similar patterns in other lakes across the globe. This module simulates the contemporary evolution of threespine stickleback in Loberg Lake, Alaska. Loberg Lake is a small (~4.5 hectares) lake in Southern Alaska.
