After learning calculus and linear algebra, it's time for differential equations! This is one of the most important topics in mathematics, especially for those who are interested in physics and engineering, as these equations show up...

With an understanding of individual organisms, let's take a look at population ecology, which looks at the dynamics of populations of organisms. How do populations grow? How are they structured? What is their geography? There is a lot to...

When it comes to mammals, we are the only species that drinks milk directly from other species, or we are the only one that does so in adulthood. Most juvenile animals can drink and digest their mothers milk because they carry the enzyme...

Exploring models which describe changes in birth and death rates as countries go through five stages of development. How does development impact population age and rate of change? Human Geography - A Changing World - Learning Points. The...

Explore the concept of the sixth extinction, a period marked by significant biodiversity loss primarily due to human activities. This video delves into how climate change, industrial agriculture, pollution, and overhunting contribute...

Dive into the world of genes and genetic diversity to uncover how these fundamental elements of heredity shape both individual traits and species survival. Explore real-world examples, like the plight of Tasmanian devils, to grasp how...

Much of the conversation around climate change centers on things like lowering carbon emissions, which is obviously critical, but we think the public health response to climate change should be a larger part of the conversation. Whatever...

A powerful journey of hope and transformation from the streets to the library

Dive into the world of the hellbender, a peculiar-looking salamander, often referred to as the Devil Dog, Snot Otter, or even the Lasagne Lizard. Follow wildlife biologist Wes Larson and researcher Emily Nolan in eastern Tennessee as...

A powerful journey of hope and transformation from the streets to the library

Now that we know about nutrient cycling, we are ready to look at food webs as a whole. These represent feeding relationships within a community.These relationships designate certain trophic levels, so let's learn about what these mean...

Ecology is all about how organisms interact. This video explores important terms like interdependence, community, habitat, ecosystem, competition and more while exploring what ecology really is.

For ecosystems to function they need energy; and we can see how this energy moves through ecosystems with food chains. We also explore how the populations of predators and prey vary over time with predator prey cycles.

Dr. Forrester defines the term ecosystem and talks about the factors that have a negative effect on them. Dr. Forrester will also discuss measures that can be taken to help preserve our ecosystems.

"Random Sampling of Populations" uses random sampling to identify the populations of two states in word problems in order to solve.

The US imprisons more people than any other country in the world. Today, Danielle explores why so many Americans are incarcerated and why we've turned to private prisons to hold that population.

Greece’s population is falling fast, with low birth rates and economic instability hitting its island communities hardest. An unconventional new organisation, Hope Genesis, is attempting to inject life back into these remote areas...

Season 3, Pygmy Crocs part 1

Pygmy crocodiles are unique in many ways and small in size. Their population has been isolated due to changes in water levels. On this mission, Kayne must catch one of these crocodiles in order to take...

The best way to start a study of ecology is to look at the scales of ecology, from the smallest things the field studies, to the biggest. On the small end, ecologists can study individual organisms, as well as populations of those...

Moving on from organisms and populations, the next tier on the scales of ecology is communities. These involve all the populations of organisms of different species that live in an area. How do they interact? How is the community...

This video explains population versus sample.<br<br/>/>

This clip is from the chapter "Exploratory Data Analysis" of the series "R Programming for Statistics and Data Science".This section explains exploratory data analysis.

In this Nature League Field Trip, Brit goes on a Montana safari at the National Bison Range and shares some local stories of how species have persisted over time via reproduction.
