Plant Defenses: How Plants Avoid Being Eaten

Просмотров 37 тыс.5 лет назад

Plants are under attack by large and small animals. They can't run away, so what strategies do plants have to escape their predators? Plants use mechanical defenses like thorns, chemical defenses, and animal body guards to protect themselves. Beautifully illustrated and explained. This is one of the many Cornell University's Naturalist Outreach Videos (https;//ruclips.net/user/naturalistoutreac...

Insect Phylogeny: Understanding evolutionary relationships

Просмотров 22 тыс.7 лет назад

To better understand the relationships among insects and other organisms, scientists compare the similarities and differences in morphological and molecular traits of different species. These similarities and differences of the traits determine the branching patterns of the evolutionary tree or phylogeny. Museum collections are extremely useful for making comparisons among organisms. The video ...
