Natural range expansion and local extirpation of an exotic psittacine--an unsuccessful colonization attempt Natural range expansion and local extirpation of an exotic psittacine--an unsuccessful colonization attempt
The Brown-throated Parakeet Aratinga pertinax is native to Panama, northern South America, and the islands off the northern coast of Venezuela. It is widely believed that the parakeet was introduced to St. Thomas, Virgin Islands, from Curacao before the mid-19th century, although no records exist as to when and how this may have occurred.

Re-exposure of mallards to selenium after chronic exposure Re-exposure of mallards to selenium after chronic exposure
Adult male mallards (Anas platyrhynchos) were fed a control diet or a diet containing 15 ppm selenium as seleno-D,L-methionine for 21 weeks. After this initial exposure, the mallards were fed untreated food for 12 weeks, then were re-exposed to selenium at 100 ppm for five weeks. During re-exposure to 100 ppm selenium, the birds that had previously been exposed to 15 ppm selenium and...

Acidic Depositions: Effects on Wildlife and Habitats Acidic Depositions: Effects on Wildlife and Habitats
The phenomenon of 'acid rain' is not new; it was recognized in the mid-1800s in industrialized Europe. In the 1960s a synthesis of information about acidification began in Europe, along with predictions of ecological effects. In the U.S. studies of acidification began in the 1920s. By the late 1970s research efforts in the U.S. and Canada were better coordinated and in 1980 a 10-year...
