If you are stuck to a rock it is tricky to get close enough to a partner to mate. One solution to this problem would be to release eggs or sperm into the open water, which is what many animals in this situation do. Acorn barnacles (Semibalanus balanoides), however, found a different solution. They have evolved the longest penis relative to their body size of any animal. In this video the penises of several barnacles are probing the neighborhood for mates. The penis is re-grown each mating season.

Riley Thompson made this animation about the fascinating lifecycle of narco babies. We usually don’t think of babies that grow inside their mothers as parasites, but sometimes the lines get very blurry. This is especially true in Narcomedusae, a group of poorly known jellyfish found throughout the world’s oceans.

This video demonstrates some of the features of PhyloTree. It then shows the early explosive discovery of mammal species (most major mammal groups were discovered early on), and then shows the slow and steady discovery of cnidarians (many cnidarians remain to be described). The tool can also be used to quickly find the first species that was described in a group. The first siphonophore to be described, for example, was Physalia physalis (the Portuguese man o’ war).

Here is a semi-interactive video (with the option of a single, non-interactive video here) from CreatureCast alum Sophia Tintori, featuring tips from a handful of ocean-dwellers that each have drastically different approaches to being invisible.

Humans are social animals; social demands, both cooperative and competitive, structure our development, our brain and our mind. This course covers social development, social behaviour, social cognition and social neuroscience, in both human and non-human social animals. Topics include altruism, empathy, communication, theory of mind, aggression, power, groups, mating, and morality. Methods include evolutionary biology, neuroscience, cognitive science, social psychology and anthropology.

A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. In pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish plants as well as observations of "the water cycle" in their terrariums. At the conclusion of their experiments, students will share their results with the class and discuss how water, Earth materials, and air are all necessary to support living things. The purpose of the activity is to acquaint students with the hydrosphere, geosphere, atmosphere, and biosphere more closely, to have students use microcosms to study natural phenomena, and to introduce students to the concept of a "fair test" in a scientific investigation. After completing this activity, students will know about the importance of the hydrosphere, geosphere, and atmosphere in supporting the biosphere. They will learn how to set up "fair test", record detailed observations, use drawings as scientific records, make sense of experimental results, and share them publicly.

Lesson 1 introduces students to the blow fly's life cycle and the accumulated degree hour (ADH) used by forensic entomologists for estimating the time of death. Lesson 2 introduces Dr. Krinsky's entomological work in solving a murder case in 1986. Students access several primary-source documents related to Dr. Krinsky's entomological work. Both lessons help students expand their understanding of a forensic entomologist's work and appreciate how scientists account for environmental/variable factors in forming a conclusion in a scientific study.

a Canadian perspective
Long Description: This textbook is intended to provide the core elements of a curriculum for teaching environmental science at the introductory level in Canadian colleges and universities. This book is suitable for students beginning a program in environmental science, environmental studies, or sustainability. It is also appropriate for arts students who require a science elective, and for science students who require a non-major elective. Not many introductory textbooks in environmental science are written in a way that provides a deep examination of issues that are particularly important in Canada, and the ways they are being dealt with by governments and society-at-large. Canada has unique national and regional perspectives that should be understood by Canadian students, and it is regrettable that many of them are studying from textbooks whose focus is not their own country. This book, however, was written from the ground-up to provide Canadian information and examples. This national context is integrated throughout the text, along with North American and global data that provide a broader perspective. Special Canadian Focus boxes illustrate important examples of environmental issues in our national context. At the same time, Global Focus boxes enhance the international context for learning about issues, while In Detail boxes examine particular topics in greater depth.
