AH-CHOO!: A Case Study on Climate Change and Allergies
Conditions of Use:
Read the Fine Print
Rating

As the carbon dioxide concentration of our atmosphere increases and our climate warms, the hay fever season seems to be getting longer and more severe. In this case study, students assume the a role of a public relations specialist contracted to communicate the link between climate change and pollen allergies. The activity focuses on the importance of scientific skills to careers outside science, and is most suitable for a lower-level introductory biology, human health, or environmental science course.

The Beautiful Tricks of Flowers
Rating

In this visually dazzling talk, Jonathan Drori shows the extraordinary ways flowering plants -- over a quarter million species -- have evolved to attract insects to spread their pollen: growing 'landing-strips' to guide the insects in, shining in ultraviolet, building elaborate traps, and even mimicking other insects in heat. Jonathan Drori commissioned the BBC's very first websites, one highlight in a long career devoted to online culture and educational media -- and understanding how we learn. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 14-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

BeeVisit enables students to evaluate the relative contributions of different pollinator species to a plant's reproductive success through an interactive model of pollen transfer.The model tracks a plant's presentation of pollen through time; pollen may be presented gradually or all at once, and the program lets you choose from a family of power curves to model the shape of the cumulative pollen presentation curve over a set number of time intervals (usually 100). Then, 'bees' of 1, 2, or 3 types are allowed to visit the plant.You specify the expected number and type of visits; this sets the probability of a visit occurring during each interval, and visits occur stochastically according to these probabilities.

Bees: The Invaluable Master Pollinators
Conditions of Use:
Read the Fine Print
Rating

The study of biomimicry and sustainable design promises great benefits in design applications, offering cost-effective, resourceful, non-polluting avenues for new enterprise. An important final caveat for students to understand is that once copied, species are not expendable. Biomimicry is intended to help people by identifying natural functions from which to pattern human-driven services. Biomimicry was never intended to replace species. Ecosystems remain in critical need of ongoing protection and biodiversity must be preserved for the overall health of the planet. This activity addresses the negative ramifications of species decline. For example, pollinators such as bees are a vital work force in agriculture. They perform an irreplaceable task in ensuring the harvest of most fruit and vegetable crops. In the face of the unexplained colony collapse disorder, we are only now beginning to understand how invaluable these insects are in keeping food costs down and even making the existence of these foods possible for humans.

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.

Developmental Selection
Conditions of Use:

Rating

The Developmental Selection module is a research simulation that allows students to investigate the possible causes of incomplete embryo development in perennial legume fruits.Two competing hypotheses are proposed to explain patterns of seed abortion - the pollen tube competition hypothesis and the maternal resource limitation hypotheses. Students can explore these competing hypotheses by setting up experimental problems and then collecting and analyzing their data.The Developmental Selection interface includes three sliders that the student can control to influence seed abortion rates (Seed/Ovule Ratio) and the relative influence of pollen tube competition (PTC) and maternal resource limitation (MRL).Other interfaces emphasize data collection, data analysis and a summary of observations.

Palynology research scientists from around the world contribute pollen data to the NOAA Paleoclimatology World Data Center (WDC). There are pollen counts, related information, and various derived data sets. Users can access or contribute data. There are several links on obtaining WDC data, other data archives, software (including Tilia and PALYHELP), and other paleoclimatology, climatology, and botany sites.

This online article, from Biodiversity Counts, offers insight into how plants interact with arthropods. It has: an explanation of the difference between detrimental and mutually beneficial relationships; some of the chemical and mechanical modifications plants have made to attract helpful arthropods and fend off harmful ones; a detailed overview of pollination, with descriptions of seven common pollination syndromes; a detailed overview of plant defense mechanisms; and a series of questions students can ask when they see an arthropod on a plant in order to learn more about how the two are interacting.
