Blue Land Crab (Cardisoma guanhumi)

Mark Hostetler, Frank J. Mazzotti, yAmy K. Taylor

The giant land crab is the largest of Florida's semi-terrestrial crabs. This animal can measure up to 6 in (15 cm) across its carapace (Figure 1). In its juvenile form, the crab is a dark brown, purple, or orange in color. As an adult, it is a bluish-gray color. Females sometimes appear light gray or white. One claw is larger than the other and the walking legs are sparsely hairy.

Why do we need environmental monitoring for Everglades restoration?

Frank J. Mazzotti yRebecca G. Harvey
Otros contactos: Venetia S. Briggs-Gonzalez, Eric Suarez, yAaron I. Chimelis

Monitoring ecosystems is similar to monitoring human health. There are both short-term and long-term indicators of ecosystem health. In general, however, ecosystems require long-term monitoring because they are complex and sensitive, and because they change slowly. Ecosystem monitoring means measuring physical, chemical, and/or biological variables over time to provide information on ecosystem change. It is only through such careful observation that we can evaluate the health of our natural resources and make science-based management decisions.

Conservation of Bats in Florida

Holly K. Ober and Frank J. Mazzotti

Bats are declining throughout North America, including Florida. This is worrisome because bats are an essential part of natural ecosystems throughout the world, serving as valuable allies to humans by consuming enormous quantities of night-flying insects, many of which are pests to humans and to crops. In tropical countries, bats also play a vital role in pollinating flowers and dispersing seeds.

Native and Nonnative Crocodilians of Florida

Otros contactos: Venetia S. Briggs-Gonzalez, Eric Suarez, yAaron I. Chimelis

Florida has two native species of crocodilians, the American alligator (Alligator mississippiensis) and the American crocodile (Crocodylus acutus). These federally protected species are easily confused with nonnative crocodilians found in south Florida, such as the spectacled caiman (Caiman crocodilus) and the Nile crocodile (Crocodylus niloticus). Some key features used to distinguish these animals are the shape of the head, the shape of the snout, and the pattern of nuchal scutes (bony plates in between head and shoulders). It is important to report all nonnative crocodilians so that researchers may quickly remove them in order to protect Florida's native ecosystems.

Ecological Risk Assessment for Invasive Wildlife in Florida

Otros contactos: Eric Suarez yAaron I. Chimelis

Global trade and travel transport plants and animals from native ranges to new ecosystems. About 10–20% of nonnative (exotic, alien) species that arrive in new locales become invasive, meaning they are likely to harm the environment, economy, or public health. Preventing the introduction of invasive species is the most effective way to protect native biodiversity and ecosystem integrity. Once an invader begins to establish and spread, its control costs increase rapidly.

The American Crocodile: An Indicator Species for Everglades Restoration

Rebecca G. Harvey, Michiko Squires, Jeff Beauchamp, Frank J. Mazzotti, yLaura A. Brandt
Otros contactos: Venetia S. Briggs-Gonzalez, Eric Suarez, yAaron I. Chimelis

The American crocodile (Crocodylus acutus) is a top predator that lives along the southern tip of peninsular Florida. Crocodiles inhabit saltwater, brackish water, or freshwater near coastal areas in mangrove-lined ponds, creeks, coves, man-made ponds, and canals. In 1975, the American crocodile was federally listed as an endangered species. Conservation and management have helped the south Florida crocodile population rebound, resulting in its downlisting to threatened in 2007. However, habitat modification and decreased freshwater flow to estuaries still present ongoing concerns for this threatened species.

The American alligator (Alligator mississippiensis) is an effective indicator for restoration of more natural patterns of water levels and flows through the Everglades. The Florida Everglades is a highly modified system, so monitoring health of alligators can inform how different areas of this large ecosystem are doing. Based on an increase in reports of very skinny alligators, biologists and natural resource managers are seeking help from the public to better understand where and when this problem occurs. This fact sheet serves as a guide for citizen scientists on how to score alligator body condition and report sightings of very skinny or unhealthy alligators.

Belize is home to over 605 bird species. At least 20 percent are migrants, choosing to overwinter in the lush tropics and contributing to incredible avifaunal diversity. In northern Belize, migrants are seen earlier than in other parts of the country, making this area a true birder's paradise. Along the New River and associated marshes, a multitude of birds can be seen. Here we present some of the most common and some of the rarest long-legged wading bird species you may encounter along the way.

The Unnatural History of Invasive Species in the Florida Keys: Paradise Threatened but not Lost

Jenna Cole, Melissa A. Miller, Paul Evans, Rosemarie Moore, and Frank J. Mazzotti

Non-native species are animals and plants living outside of their native ranges as a result of human activity. The specific introduction of a species to an area can occur intentionally or unintentionally. A few introduced non-native species will become established (breed) and can become invasive species capable of harming ecosystems, economies, or human health and safety. The establishment of invasive species can follow a trend known as the “invasion curve.” The longer invasive species remain in an area, the more severe their impact, the higher the chance for their distribution, and the greater the expense to manage them. Invasive species like the Burmese python and the lionfish have already harmed Florida Keys ecosystems. The Keys are particularly susceptible to invasion because of their tropical climate, island geography, and abundance of the disturbed habitats that help invasive species establish and spread. Early detection of new species is vital to saving Keys native species.
