Flowering Phenology: An Activity to Introduce Human & Environmental Effects on Plant Reproduction
Neil, Kaesha
American Biology Teacher, v71 n5 p300-304 May 2009
Global and local climate change has become an important topic in the last few years. Concerns regarding the impact of climate changes on ecosystems in general, resources used by humans (e.g., water, energy, crops), and the intensity and frequency of natural disasters are driving the interest. Phenology is one way researchers are studying historic and current climate changes and repercussions. Phenology is the timing of biological events (i.e., growth and reproduction) influenced by environmental conditions. Genes and their interactions with the environment determine the timing and duration of these events. Temperature, moisture, and photoperiod are three important triggers for phenological events for both animals and plants. This article presents a lesson that involves an activity to introduce the concept of flowering phenology and synchrony with pollinators and an optional, but highly recommended, lab. The lesson provides an opportunity to teach (1) what is flowering phenology; (2) the interrelationships between climate, community dynamics, and plant fitness (especially pollinators); and (3) how local climate conditions may be changing (due to urbanization and global climate changes) and the influence of those changes on local flora and fauna. (Contains 1 figure and 2 tables.)
