In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.
This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.
This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.
This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.
This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population.
This interactive module explores key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity.
This playlist can be used in an online, undergraduate (majors-level) introductory biology lab to incorporate core topics in cellular and molecular biology.
This playlist can be used in an online, undergraduate (majors-level) introductory biology lab to incorporate core topics in evolution, diversity of life, and ecology.
This playlist can be used to teach several core concepts of population dynamics and trophic cascades through three diverse ecological examples: wolves in Isle Royale, Michigan; rinderpest and wildebeest in Tanzania; and cougars in Zion National Park, Utah. It can be used in general biology and environmental high school courses.
