Not just nuts

Article Abstract:

Certain rainforest plant products have commercial importance, but little research has been done into their biology or their place in the ecosystem of the rainforest. Brazil nuts are harvested exclusively from their wild habitat unlike most other nuts which are grown on plantations. The Brazil nut tree plays a direct role in the lives of the rodent and bird populations of the forest and may have effects on their predators. Plant products from the rainforest should not be harvested with abandon, but with a careful management plan that takes into account their ecological roles.

Ants with attitudes: how else would you describe ants that can kill and devour a one-half-pound rat in just a few hours?

Article Abstract:

The spread of fire ants through the southern US is wreaking havoc on ecosystems and native species. Imported accidentally from Brazil in the 1940s, they can reduce other ant species in an area by 70%, cut bird nesting success 30%, and drive many birds and rodents entirely out of some areas. Pesticides proved more effective against the fire ants' competitors, clearing the way for their spread. Pygmy mice seem to adapt well to their presence, but other rodents are faring poorly, with dreadful implications.

Treasure islands ... just off the Florida Gulf Coast

Article Abstract:

The Sanibel and Captiva barrier islands off of Florida's gulf Coast offer amateur biologists and wildlife observers ample chances to see numerous unusual animals and plants in their natural habitat. Many varieties of shellfish wash up on the beach. Manatees use the islands as resting grounds, and bird of many varieties can be seen in the grasses. the islands have continuing problems with introduced exotic species of plants and animals, which are threatening some of the area's ecosystem.
