Carpenter beeLast Updated on 2014-06-26 17:31:14
This hexapod (six-legged) insect is a bee in the subfamily Xylocoinae of either the genus Ceratina or Xylocopa that makes its nest in wood or plant stems.
Along with bumble bee queens, carpenter bees (genus Xylocopa) are the largest native bees in the United States. There are numerous species of carpenter bees that inhabit a broad range of ecosystems from tropical to subtropical to temperate. In the United States carpenters bees can be found across the southern United States from Arizona to Florida and in the eastern United States, north to New York.
These gentle giants get their name from their life history habits of excavating precisely rounded galleries inside wood. Using their broad, strong mandibles (jaws), they chew into dead but non-decayed limbs or trunks of standing dead trees. Some species, like the eastern Xylocopa virginica, occasionally take up residence... More »

Asian Carp and the Great Lakes RegionLast Updated on 2014-06-20 13:48:30
Alien species of Asian carp are a significant ongoing adverse ecological threat to the Great Lakes of North America. Chief pathways for the introduction of these species has been from the waterways of the city of Chicago, Illinois. The U.S. Congress and federal regulatory agencies are investigating protocols to reduce alien species influxes from Chicago waterways into the Great Lakes, whose fishery value is approximately seven billion dollars per annum. The city of Chicago has resisted environmental protection initiatives, on the grounds that the city's commercial interests may be harmed.
Four species of non-indigenous Asian carp are expanding their range in U.S. waterways, resulting in a variety of concerns and problems. Three species—bighead, silver, and black carp—are of particular note, based on the perceived degree of environmental concern. Current controversy... More »
Florida Black BearLast Updated on 2013-10-29 16:30:17When the American black bear (Ursus americanus) in Florida was first scientifically described in 1896 by naturalist C. Hart Merriam, he thought its long skull and highly arched nasal bones distinguished it from black bears in other areas and classified it as a separate species (Ursus floridanus), which he called the Everglades bear. Subsequent analyses around 1960 revised the status of these bears to the Florida black bear (U. a. floridanus), one of 16 recognized subspecies .
Species:-- Ursus americanus Pallas, 1780
