Living with Sumatran Elephants | EARTH A New Wild

Elephants and humans are both ecosystem engineers on the island of Sumatra, but with both requiring large territory in the forest, coexisting has not always been easy in a rainforest with limited space and resources. Elephants play a crucial role in maintaining a healthy environment, but with humans now trying to build farms that border the forest, both species became at risk. Today, elephant trainers are beginning to work with the local animals to safely protect the forest for humans and animals alike.

The Decline of Vultures in Nepal | EARTH A New Wild

In this interview, hear a first-hand account of the drastic decline of wild vultures in Nepal. Due to a veterinary drug used on cattle known as Diclofenac, several species of vultures have seen an unprecedented decline in number within the past few decades; today, with a better awareness of vultures and their roles in the ecosystem, scientists have been able to slow the decline and hope to see the population return back to healthy numbers. As shown in this video, parahawking is a variation of paragliding in which riders are paired with trained birds, often birds of prey, to get an up-close experience with these misunderstood animals. Use this video to demonstrate a unique case of ecotourism, and to give a background on the decline of vultures in Southern Asia.

A Lemon Shark Gives Birth | EARTH A New Wild

In order to continue the tagging and research of lemon sharks, marine scientists in Florida assist in the birth of two shark pups. Lemon sharks, like most sharks, are viviparous, meaning they give birth to live young. Mother lemon sharks migrate to warm, shallow nursery waters to give birth in a safe environment. Use this resource to demonstrate field research and marine biology, as well as shark biology and reproduction.

Mahouts and Elephants | EARTH A New Wild

The name Mahout is a traditional Hindi word used to refer to riders and tamers of elephants. In Sumatra, contemporary Mahouts work with trained elephants to protect farms and villages from wild elephants, which have been known to act aggressively towards humans that have been expanding into the local forest. Use this resource to educate students on the Sumatran culture and mutualistic relationships between humans and animals.

Tagging and Tracking Sharks | EARTH A New Wild

Shark researcher Richard Fitzpatrick works with his team off the coast of Australia to capture, tag, and release sharks. In this video, watch as his team catches a tiger shark and places a tracking tag into its dorsal fin. Use this video to introduce students to marine biology and field research, and to explain certain concepts of ocean management and the conservation of large marine predators.

Fishing Over the Decades | EARTH A New Wild

By looking at the record of Florida fishermen and their hauls over the decades, scientists see a clear trend that indicates the harmful impact of overfishing. Research into overfishing shows an immediate impact in the size and quantity of available fish, but also many hidden effects that often go unnoticed, like oxygen levels in the water or the abundance of bacteria. Use this resource to illustrate the impacts of overfishing on marine ecology.

Overfishing and Parasitic Snails | EARTH A New Wild

In this interview with a biologist, we learn that the overfishing of Lake Malawi in Africa has resulted in an unexpected effect on the residents of the area. Parasitic snail larvae have been infecting residents with a disease known as bilharzia; the disease was never an issue when the snails were predated by abundant populations of fish, but a decrease in the predator population has resulted in a surge in snail activity. Use this video to teach concepts such as predator/prey relationships, population ecology, and the results of overfishing.

Tuna Tagging | EARTH A New Wild

Marine researchers are undertaking massive endeavors to track, catch, tag, and release record numbers of tuna. This artful video shows the process from start to finish, as fishermen locate and catch tuna for scientists to tag and release back into the ocean, allowing them to more accurately track the migratory patterns of these fish in hopes of alleviating the pressures of overfishing.

Mouthbrooding Fish | EARTH A New Wild

Some species of fish and frogs provide protection for their young by sheltering offspring inside their mouth. This behavior, known as mouthbrooding, is believed by scientists to have evolved independently in several lineages of fish. Use this video to demonstrate fish behavior and reproductive biology, or to introduce the concept of convergent evolution in animal behavior.

The Sami, also known as Laplanders, are people indigenous to Scandinavia. This interview with a reindeer herder showcases Sami culture, touching on they have adapted over the years to a more modern form of living. The culture places a great importance on the husbandry of reindeer, a profession now illegal for anyone other than the Sami to practice. Use this resource to introduce students to the Sami culture, specifically regarding reindeer, clothing, and their adoption of a modern way of life.
