In this Science Update, from Science NetLinks, students listen to an interview with Kevin Kelly, co-founder and board chairman of the All Species Foundation in San Francisco. Kelly discusses his mission to discover, identify, and document every species on Earth within the next 25 years. Students then read more information about the project, and conclude by answering some related questions. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.
Learn about the structure and function of living organisms by drawing an imaginary animal in the Take the Stage game show, ANIMAL SURVIVAL! Viewers become contestants on a game show and are challenged to draw an imaginary animal that could live and survive in either the desert, ocean, or the arctic tundra. When drawing the imaginary animal, the contestants write out two distinct structures and a function for each of the structures that help it survive. Learning Objective: Compare the structures and functions of different species that help them live and survive in a specific environment.
Step outside and discover the diversity of insect life in your neighborhood. Insects are the world’s most diverse group of living things, with over 950,000 identified species and counting. You might think that you’d need to travel to the Amazon to study insects, but they can be found practically everywhere—including right where you happen to be.
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Define species and describe how species are identified as differentDescribe genetic variables that lead to speciationIdentify prezygotic and postzygotic reproductive barriersExplain allopatric and sympatric speciationDescribe adaptive radiation
By the end of this section, you will be able to:Discuss the need for a comprehensive classification systemList the different levels of the taxonomic classification systemDescribe how systematics and taxonomy relate to phylogenyDiscuss the components and purpose of a phylogenetic tree
This 9-minute video lesson discusses what a species is and isn't. It considers ligers, tiglons, mule, hinnies, and dogs. [Biology playlist: Lesson 61 of 71].
This is the second in a series of modules which detail the research of Charles Darwin and evolutionary theory. This module continues with a discussion of the processes that led to Darwin's formulation of the theory of natural selection.
After learning about and observing the differences between flowering and nonflowering plants, students go outside and search for plants in schoolyard, keeping notes and drawings of their observations.
Students apply their understanding of physical characteristics and biological classification of different organisms through a game of classification "Go Fish!"
In this lesson, from Science NetLinks, students will get acquainted with diverse forms of life by using modern biological classification systems to group animals that are related. Students will learn about basic scientific groupings like genus, species, mammals, fish, birds, amphibians, and reptiles. One of the websites featured in this lesson allows them to pair different vertebrate animals and learn more about their common traits. By doing this, students will begin to classify organisms in a more sophisticated way.
This activity is a field investigation where students observe plants, animals, and insects that are common to Minnesota.

Recently, designer mutts like the Labradoodle -- a cross between a Labarador retriever and a poodle -- have become popular. A listener wanted to know if some kinds of dogs are just too different to make puppies. This Science Update explores the cross breeding of species.
The ecological impacts of climate change are broad and diverse, altering species' range limits, plant phenology and growth, carbon and nutrient cycling, as well as biodiversity and extinction risk. Recent PLOS articles have used a variety of experimental and observational approaches to examine these impacts. The broad range of papers within this Collection emphasize not only the multi-faceted impacts of climate change on ecological and human systems, but also the breadth and depth of research on these subjects being reported in PLOS journals.
Students synthesize their understanding of energy flow and trophic relationships through “Food Chains Rummy,” a modified version of the classic card game using Species Cards.
