Community ecology is the study of interactions between different species of living things, and lets ecologists examine the effects of predator-prey relationships, parasites, and mutually beneficial interactions. In this episode of Crash...

What is the derivative of a^x? Why is e^x its own derivative? This video shows how to think about the rule for differentiating exponential functions.

They're the second-largest fish in the world, they're almost extinct, and we know almost nothing about them. In this talk, Simon Berrow describes the fascinating basking shark ("great fish of the sun" in Irish), and the exceptional --...

Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density...

Paul Andersen shows you how we can use a spreadsheet to model population changes. He begins with a brief discussion of populations and life cycles. He then shows you how you can model a single generation using a spreadsheet.

Paul Andersen explains how populations experience exponential. He begins by address the major players; N (population size) and r (growth rate). He models population growth in rabbits through four generations. He then shows you how to...

Is the world overpopulated or underpopulated? While we worry about there being too many people for the planet to support, we can also worry about how fewer people in a given place may affect the economy, what may happen when there are...

In this video Paul Andersen explains how population ecology studies the density, distribution, size, sex ration, and age structure of populations. Intrinsic growth rate and exponential growth calculations are included along with a...

In this video Paul Andersen explains how the world population has undergone exponential growth since the industrial revolution. Predicting the future world population is difficult because each country will grow at different rates. ...

This lecture will explain the fundamental difference between a sample and a population in statistical data.

The Capture-Mark-Recapture (CMR) method is an ecological technique used to estimate animal population sizes by capturing, marking, releasing, and later recapturing individuals to analyze the proportion of marked specimens. This...

Dive into the world of advanced data visualization using incredible tables created with gtExtras in R! This video is perfect for data scientists, statisticians, and R programming enthusiasts looking to enhance their data presentation...

From the western gorilla to the blue whale, thousands of animal species are under various levels of threat. What can we do to protect them or is it already too late? Biology - Adaptation And Evolution - Learning Points. An astounding...

In this video, the presenter explains the fundamentals of labor markets and how economists study them. They discuss the downward sloping labor demand curve, and how higher wage rates cause firms to demand fewer workers. They also explain...

This video is part of a series of videos that consider data analysis using R programming. It is primarily for beginners. In this video I talk about using R to visualise your data. Data visualization using R is best done using the ggplot...

Direct age standardization and indirect age standardization are two methods for comparing the mortality rates of two populations. This is sometimes called the age adjusted mortality rate. These are methods used in public health and...

The video discusses the concept of a community in an ecosystem and the levels of organization within it. It covers the role of photosynthetic organisms in producing biomass, the different types of consumers (primary, secondary, and...

It describes the role of biological agents for controlling pests. It describes genetically modified organisms (using Bt microbe) and their uses as biocontrol agents.

This nugget explains the different growth models in population ; exponential growth and logistic growth and their attributes
