The morning light guides you to the water, dressed in gloves, a long-sleeved shirt and tall rubber boots. You make this trek with a sieve extended by a long pole in hand as you collect snails, ranging in size from half-an-inch to an inch long, being careful to not expose yourself to parasitic flatworms that infest the waters. This is just another morning of summer vacation for Lamar University junior biology major Emily McCall of Orangfield, who spent two weeks performing field research in Kenya.
