  • Age Structure of Ebola Outbreaks

    Age Structure of Ebola Outbreaks

    Data Point

    Scientists analyzed demographics, including sex and age, of the spread of the Ebola Virus Disease during seven outbreaks in the Democratic Republic of Congo.

  • Vertebrate Declines and the Sixth Mass Extinction

    Vertebrate Declines and the Sixth Mass Extinction

    Data Point

    In this study, researchers measured species population declines on a global scale that may contribute to the sixth mass extinction.

  • Predator-Prey Relationship Dynamics

    Predator-Prey Relationship Dynamics

    Data Point

    In a study in Greenland, scientists examined whether changes in population densities of Arctic fox are related to changes in population densities of its main prey, the lemming.

  • Tracking Genetically Modified Mosquitoes

    Tracking Genetically Modified Mosquitoes

    Activity

    Genetically modified mosquitoes have been used to reduce mosquito populations and the diseases they spread. But how can we tell if the method works? In this activity, students analyze data from a field experiment.

  • Population Dynamics

    Population Dynamics

    Click & Learn

    Explore the exponential and the logistic growth mathematical models that describe how population changes with time.

  • The Great Elephant Census Modeling Activity

    The Great Elephant Census Modeling Activity

    Activity

    In this classroom activity, students will model two types of counting methods, sample counts and total counts, to determine population size. 

  • Film Guide for Some Animals are More Equal than Others

    Film Guide for Some Animals are More Equal than Others

    Film Guide

    The following classroom-ready resources complement the film Some Animals Are More Equal Than Others: Trophic Cascades and Keystone Species. It tells the story of the bold experiments by Robert Paine and James Estes, which established the importance of keystone species in regulating ecological communities and the cascades of effects set in motion by their removal.

  • Using Genetic Evidence to Identify Ivory Poaching Hotspots

    Using Genetic Evidence to Identify Ivory Poaching Hotspots

    Data Point

    A team of scientists analyzed the DNA from seized ivory to determine where the ivory from poached elephants came from.

  • CSI Wildlife

    CSI Wildlife

    Click & Learn

    In this interactive, students use DNA profiling, or fingerprinting, to solve two cases of elephant poaching. In the process they will learn about genetic markers, PCR, gel electrophoresis, allele frequencies, and population genetics.

  • Survey Methods

    Survey Methods

    Click & Learn

    In this interactive, students explore the methods scientists use to survey elephants and learn about the current state of the elephant population in Africa.

  • The Great Elephant Census

    The Great Elephant Census

    Scientists at Work

    (8 min 23 sec) How many African elephants are left and where are they? This video follows the work of researchers conducting the first census of African savanna elephants in over 40 years and the methods they are using to obtain accurate, up-to-date numbers across the continent. 

  • Elephants

    Elephants

    Collection

    Students will learn about DNA profiling (or fingerprinting), how population sizes are measured, genetic bottlenecks, and how sound travels, as they explore several interactives and videos based on...

  • WildCam Lab

    WildCam Lab

    Click & Learn

    The WildCam Lab is a part of WildCam Gorongosa, an online citizen science platform where users identify animals in trail camera photos. Using the WildCam Lab, students can investigate ecological questions and test hypotheses by exploring trail camera data using an interactive map. 

  • Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades

    Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades

    Short Film

    (19 min 29 sec) Keystone species and trophic cascades are fundamental concepts in ecology. This short film tells the story of how these concepts were first established through the pioneering experiments of two young researchers: Robert Paine and James Estes.

  • Modeling Populations and Species Interactions

    Modeling Populations and Species Interactions

    Lecture

    (30 min 38 sec) Gorongosa National Park in Mozambique provides several examples for how to model the growth of animal populations and then check the models against actual data. 

  • Patterns and Processes in Ecology

    Patterns and Processes in Ecology

    Lecture

    What controls the numbers and distributions of animals in their environment? How do animals interact with other species? How do natural patterns arise in nature? Find out in the 2015 Holiday Lectures on Science.

  • WildCam Gorongosa

    WildCam Gorongosa

    Click & Learn

    Researchers in Gorongosa National Park use remote trail cameras to study the park’s wildlife. You can contribute to this important research through WildCam Gorongosa, an online citizen science platform.
