Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous,...

In the world of ecology, the only constant is change - but change can be good. Today Hank explains ecological succession and how ecological communities change over time to become beautiful, biodiverse mosaics.

Discover a process that truly demonstrates nature's grit: ecological succession! The Amoeba Sisters introduce both primary and secondary succession

Hank gets to the more violent part of community ecology by describing predation and the many ways prey organisms have developed to avoid it.

Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does. The world is crammed with things, both animate and not, that have been...

With a better understanding of population ecology, we are ready to zoom out and look at community ecology, which involves interactions between species, as well as landscape ecology, which will broaden our understanding of ecosystems. How...

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...

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.

In this video we look at a few keys words that you will come across throughout ecology. An ecosystem is made up of all of the communities that live in it, every single organism from small to big and lots of environmental factors like...

Explain ecosystem, environment its biotic and abiotic components, the levels of ecological hierarchy and the branches of ecology.

In this video, the teacher covers key concepts related to communities in ecology. They discuss how different populations interact within a community, the role of limiting factors in population dynamics, and the importance of tolerance in...

Jason Wegman and his family moved to UniverCity eight years ago, drawn by the sense of community and sustainability that he also helped build. The development includes eco-friendly schools like the LEED-certified primary school and the...

Fire has been an important part of traditional, indigenous land management practices for millennia. Historically, it was used to manage resources and protect communities, contrasting with modern fire suppression policies that have led...

This video provides a brief overview of the topics covered in the Ecology Fundamentals series. It explains the terms species, population, and community, and emphasizes the importance of understanding the biotic and abiotic components of...

This live-action video program is about the term ecological succession. The program is designed to reinforce and support a student's comprehension and retention of the term ecological succession through use of video footage, photographs,...

Dive into the complex world of forest ecosystems where trees, animals, and fungi form interconnected communities. Learn about the various forest types, from tropical rainforests to boreal forests, and explore how diverse species...

This video is a lecture presentation on biotic factors. The presenter defines biotic factors and explains how they can affect communities and ecosystems. The focus is on living factors, such as availability of food, arrival of new...

The video is a lecture presentation on communities and the relationships between organisms within them. It uses an example of a community that includes an owl, a snake, a shrew, a frog, a beetle, grasshopper, and grass living in a wooded...

The video is a lecture presentation on abiotic factors. It defines what abiotic factors are and how they can impact the number and type of organisms within a community. The presenter discusses different abiotic factors such as light...

Delve into the characteristics of the biosphere, the sphere of Earth that encompasses all living organisms. Learn about biomes, ecological communities, and the vital role of life on our planet.



Earth's Materials and Systems...

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...

In this video Paul Andersen explains how ecosystems function. He begins with a description of how life on the planet is ordered from large to small in biomes, ecosystems, communities, population, and individuals. He describes the major...

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...
