The purpose of the Population Genetics Laboratory is for assessing, managing and analyzing datasets on the genetics of various species at the Population Ecology Lab Summary. Because there are so many interactions between individuals and the environment, measuring how well populations grow is often complex. Not surprisingly this is a broad topic and this unit will introduce and examine many of the different aspects of ecology including communities, populations, classification, and the greenhouse effect.

The lab explores important population biology concepts, including exponential and logistic growth and carrying capacity, using the classic predator-prey system of moose and wolves on an island in Lake Superior.

Population stability is often proceeded by a "crash" since the growing population eventually outstrips its available resources. In this lab you will get a chance to "build your own" ecosystem, and explore the effects of these interrelationships.

A population pyramid, also called an age structure diagram, is a graphical illustration that shows the distribution of various age groups in a human population typically that of a country or region of the worldwhich ideally forms The addition or removal of one species affects many other species with which it might compete for, or provide food.

Students use the bacteria E. Population ecology, life history and conservation biology — Ringsby Lab Due to heavy exploitation of natural resources particularly the last centuries we have entered a period of mass extinctions on earth where many wild species experience a steep decline in population sizes towards the brink of extinction.

Ecology is often referred to as the "study of distribution and abundance". However, ecologists cannot count and determine the location of every organism in a given area. Look at each population and determine which population has had an overall increase? We will go over this concept in detail in upcoming in-class activities and labs. The addition or removal of one species affects many other species with which it might compete for, or provide food.

Population life tables I. Census techniques will include the use of drift fence arrays, minnow trapping, and dip-netting. Population Ecology is the study of populations and their changes over time. This very popular lab has been revised to include onscreen instructions, feedback for students, and a new graphing exercise.

Then they compare growth curves of the population of each species, alone and then together.

Information on Population ecology studies the dynamics of species populations and how these populations interact with the wider environment. You will create graphs of the data to help you interpret them. Current research in the lab addresses factors that may explain the success of invasive understory species, and how drought, soil nutrients and neighbor interactions affect population and community dynamics of desert perennials in Joshua Tree National Park, California. Population Ecology Our work in population ecology broadly encompasses assessment of the sources of population growth and decline.

Some of these conditions include environmental changes such as weather, habitat quality, and food availability. Our lab conducts work in multiple areas of population biology and community ecology.

This module was developed as a pre-lab for Isle Royale or a supplement for courses that cover intro-level population biology. We employ tools from population biology, microbiology, epidemiology, microbial and community ecology, genomics, and evolutionary biology to distinguish mechanisms resulting in particular disease outcomes across species of amphibians, and contrasting disease states endemic infections vs.

The average age of Lamar Valley elk was approximately 16 years, with the oldest animals living 20—25 years. As such, I expect that students have little to no understanding of the topic. Demography - Human Population Ecology. This lab can be used in any general ecology course or an upper division ecology course.

This last one was particularly challenging for me so I took advantage of completing this assignment in order to separate myself from all the stresses of the …Population ecology. Which of the two curves exhibits exponential growth? A population is a group of interacting organisms of the same species and includes individuals of all ages or stages: The Peril River Watershed is in trouble!

Explore natural selection by controlling the environment and causing mutations in bunnies. Demonstrate how competition for natural resources in the environment can affect population growth. Andreas is generally interested in wildlife disease ecology, ecotoxicology, and conservation medicine. Introduction to Ecology Outline of Lecture 1. We use theory from population ecology, metapopulation ecology, and landscape ecology to develop hypotheses about the effects of management actions on animal population dynamics.

Ecology lab report 1. Predict how variables have different effects on population growth rates, calculate and graph changes for a given population. Individuals that do not succeed in establishing a territory find no mates and cannot breed. For example, male wolves may fight each other for territory or access to mates. This type of competition is a major force behind evolutionary change. Sometimes, the moose population on Isle Royale grows large enough that moose become easy prey for wolves.

When wolves have plenty to eat, their population grows. This causes the moose death rate to rise higher than its birthrate, so the moose population falls. Starvation raises wolves death rate and lowers their birthrate, so the wolf population also falls. When only a few predators are left, the moose death rate drops, and the cycle repeats.

From a plant s perspective, herbivores are predators. On parts of Isle Royale, large, dense moose populations can eat so much balsam fir that the population of these favorite food plants drops. When this happens, moose may suffer from lack of food.

For example, fishing fleets, by catching more and more fish every year, have raised cod death rates so high that birthrates cannot keep up. As a result, cod populations have been dropping.

With a human assist, wolves will return to Isle Royale National Park this year

These populations can recover if we scale back fishing to lower the death rate sufficiently. Biologists are studying birthrates and the age structure of the cod population to determine how many fish can be taken without threatening the survival of this population.

For example, ticks feeding on the blood of a hedgehog can transmit bacteria that cause disease. Parasitism and disease are density-dependent effects, because the denser the host population, the more easily parasites can spread from one host to another. This virus killed all but 13 wolves on the island and only three of the survivors were females.

Too much fighting can cause high levels of stress, which can weaken the body s ability to resist disease. In some species, stress from overcrowding can cause females to neglect, kill, or even eat their own offspring.

Stress from overcrowding can lower birthrates, raise death rates, or both, and can also increase rates of emigration. Unusual weather such as hurricanes, droughts, or floods, and natural disasters such as wildfires, can act as density-independent limiting factors.

In response to such factors, a population may crash. After the crash, the population may build up again quickly, or it may stay low for some time. Sometimes the effects of so-called density-independent factors can actually vary with population density. It is sometimes difficult to say that a limiting factor acts only in a densityindependent way.

On Isle Royale, for example, the moose population grew exponentially for a time after the wolf population crashed.
