Ever wonder how Earth materials and processes directly impact the distribution and health of living organisms? Academy geologist Jean DeMouthe presents a richly illustrated lecture on the nature of geologic materials and how they affect living things. She provides examples of how geologic processes affect ecosystems, from a tiny spring on a hillside to a big explosive volcanic eruption. Hear about the minerals, rocks, and soil that provide nutrients as well as substrate on and in which plants and animals live. Learn about how geological factors can produce chemical or physical barriers that affect what can and cannot live in a particular area. The talk wraps up with a discussion of how the Academy's geologic collections provide insight into and history of biodiversity and evolution.
Kyle Summers, PhD, talks about mimicry and monogamy in Peruvian poison frogs. Kyle Summers is a Professor in the Department of Biology at East Carolina University.
This lecture features Terrance Gosliner, Senior Curator and Dean of Science and Research Collections for the Academy's Department of Invertebrate Zoology.
Ants may be tiny, but they play a huge role in their ecosystems. In fact, biologists estimate that the collective weight of all the ants on Earth is equal to the weight of all humans.
In this talk, Dr. Brian Fisher describes the unique behaviors and incredible adaptations of our planet's most charismatic small animals. See how ants farm, hunt and tend "herds of livestock." Learn how primitive Dracula ants feed on their sisters' blood.
Watch the fastest recorded movement of any animal -- a feisty ant with lightning-quick jaws that Dr. Fisher filmed with one of the world's most advanced high-speed cameras. You'll also learn about Dr. Fisher's conservation efforts in Madagascar and gain new respect for our smallest neighbors.
