Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living...

Two mushroom guilds with vastly different strategies are locked in competition for forest dominance.

You've probably heard that theres a fungus among us—but how much of fungi are helpful vs harmful? Turns out there's quite a grey area! Join Stefan Chin for a new episode of SciShow and learn more about the multipurpose world of fungi!

In this video Paul Andersen shows how increasing ocean temperatures causes coral polyps to release their symbiotic algae. This process of coral bleaching decreases the availability of energy for the coral and may eventually lead to coral...

There’s no denying that fungus is all around us all the time. And not all of it is helpful, but neither is all of it harmful. Here are some of the many functions of fungi.

Paul Andersen describes how cell communication is used in both single-celled and multicellular organisms. He starts by describing the symbiotic relationship between the bobtail squid and the bacteria Vibrio fisheri. He explains how...

Whether it’s for food, protection, or a little healthy grooming, a lot of animals of different species form some surprising mutualistic relationships in nature.

Paul Andersen explains the major classification terms in ecology and how a community can be measured by species composition and species diversity. The symbiosis of leaf cutter ants is included. The podcast ends with a discussion of...

Explore several ecological relationships with The Amoeba Sisters! Ecological relationships discussed include predation, competition, and symbiotic relationships (parasitism, mutualism, and commensalism). Table of Contents: Intro 00:00...

Explore the endosymbiotic theory with the Amoeba Sisters! This theory explains the development of the eukaryote cell from prokaryote cell symbiosis. Scientific theories are also briefly defined. Table of Contents: Intro 00:00 What is a...

Hank tells us about all of the things that live on us or in us - the good, the bad, and the very, very ugly.

Paul Andersen explains how populations interact in an ecosystem. The symbiosis of several populations is based on effects that may be neutral, positive, or negative. Interactions like mutualism, commensalism and parasitism are...

When we hear the term symbiosis, we tend to think about a simple partnership between two biological organisms. But in many cases, there are more than two parties involved and it's way more complicated.

Hank's love affair with plants takes a slight hit now that he's learned about several animal species that can photosynthesize. Fortunately, he's excited enough about these animals to share them with all of us! Let SciShow introduce you...

Paul Andersen explains the concept of coevolution. He begins with an analogy comparing the relationship of humans to technology with those of coevolving species. He then discriminates between coevolution and convergent evolution. He...

An ecosystem is complex community of living organisms. The living things depend on each other and the environment they're in, from the tiniest bug to the biggest animal. Relationships between organisms are a crucial part of ecosystems....

See how the "ecosystem engineers" build the burrows that the owls live in.

Learn all about these incredible creatures, including how much a 100+ year-old tortoise weighs, and how the "Finch response" plays an important role in tortoise health.

Symbiosis is a close and evolved interaction between species, which can be obligate (necessary for survival) or facultative (optional). It includes various types: mutualism (both benefit), commensalism (one benefits, the other is...

With a better understanding of ecosystems and their habitats, we are ready to discuss behavioral ecology. This looks at how organisms interact and how this effects the ecosystem. What is foraging? What about parasitism, or mutualism? How...

In nature, some animals depend on another species for survival. The special relationship between sea anemones and clown fish demonstrates how creatures in the same habitat can rely on each other for defence. Biology - Ecosystems -...

When individuals of different species live together in a close and long-term relationship. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds using stunning images and concise textual definitions. Twig Science...

Dive into the ocean's depths to discover the unique partnership between the Pistol shrimp and Goby fish, ensuring mutual survival.

Dive into the world of unexpected animal friendships, from a lion befriending a dog to a hen mothering a duck. This video explores the curious dynamics of interspecies relationships and the scientific explanations behind them,...
