The Forest Predator You Rarely See: What the Tayra Reveals About Hidden Ecology

Yet hidden within the rushing columns is an entirely different world—one that exists because of the ants but often goes completely unnoticed. An army ant colony is not […]

While hiking through the flat expanse, I encountered hundreds of eager hover flies. I say eager, because the flies followed and buzzed around me relentlessly. While I couldn’t identify […]

Biodiversity Increases While Species Losses Continue to Climb
Defining Biodiversity Species By some measures, worldwide biodiversity may be increasing. At the same time the rate of extinction, due mostly to habitat loss, remains high, especially in tropical areas where deforestation continues at a pace noticeable to even the most unconcerned bystander. You might wonder how these statements can both be true. Biodiversity, a […]

Many fish and invertebrates that depend upon kelp to provide a habitat to hide from predators, reproduce, and find […]
