Africanized honey bees AHB are a hybrid between European and African bee subspecies which were inadvertently released in Brazil in the s Argentine Ant In addition to being a nuisance in urban settings, the Argentine ant is problematic in both natural and agricultural ecosystems.
April 19, iStock Though they're often described as "rats with wings" a phrase popularized by the movie Stardust Memoriespigeons are actually pretty cool.
From homing instincts to misleading rump feathers, here are 15 things you might not know about these avian adventurers. The common city pigeon Columba liviaalso known as the rock pigeon, might be the first bird humankind ever domesticated.
You can see them in art dating back as far as BCE in modern Iraq, and they've been a valuable source of food for thousands of years. Pigeon-breeding was a common hobby in Victorian England for everyone from well-off businessmen to average Joes, leading to some fantastically weird birds.
Few hobbyists had more enthusiasm for the breeding process than Charles Darwinwho owned a diverse flock, joined London pigeon clubs, and hobnobbed with famous breeders. Darwin's passion for the birds influenced his book The Variation of Animals and Plants Under Domestication, which has not one but two chapters about pigeons dogs and cats share a single chapter.
Nikola Tesla was another great mind who enjoyed pigeons. He used to care for injured wild pigeons in his New York City hotel room. Hands down, Tesla's favorite was a white female—about whom he once said"I loved that pigeon, I loved her as a man loves a woman and she loved me.
When she was ill, I knew and understood; she came to my room and I stayed beside her for days. I nursed her back to health. That pigeon was the joy of my life.
If she needed me, nothing else mattered. As long as I had her, there was a purpose in my life. In a Current Biology studyresearchers showed captive pigeons a series of digital lines on a computer screen for either two or eight seconds.
Some lines were short, measuring about 2. The pigeons were trained to evaluate either the length of the line or how long it was displayed.
They found that the more time a line was displayed, the longer in length the pigeon judged it to be. The reverse was true too: If the pigeons encountered a longer line, they thought it existed in time for a greater duration.
Pigeons, the scientists concluded, understand the concepts of both time and space; the researchers noted "similar results have been found with humans and other primates.
How they do this is a mystery, but people have been exploiting the pigeon's navigational skills since at least BCE, when ancient peoples would set caged pigeons free and follow them to nearby land. Their navigational skills also make pigeons great long-distance messengers.
Sports fans in ancient Greece are said to have used trained pigeons to carry the results of the Ancient Olympics. Further east, Genghis Khan stayed in touch with his allies and enemies alike through a pigeon-based postal network.
Pigeons' homing talents continued to shape history during the 20th century. In both World Warsrival nations had huge flocks of pigeon messengers.
America alone hadat its disposal in WWII. By delivering critical updates, the avians saved thousands of human lives. One racing bird named Cher Ami completed a mission that led to the rescue of stranded U. Inscientists in Holmdel, New Jersey, heard hissing noises from their antenna that would later prove to be signals from the Big Bang.The Wisconsin natural heritage working list contains species known or suspected to be rare in the state along with natural communities native to Wisconsin.

The Zebra Mussel: Invasive or just annoying?
An invasive species is %(3). The aim of this review is to provide a comprehensive update on the current classification and identification of Haemophilus and Aggregatibacter species with exclusive or predominant host specificity for humans.
Haemophilus influenzae and some of the other Haemophilus species are commonly encountered in the clinical microbiology laboratory and demonstrate a wide range of pathogenicity, .
Invasive plants or animals can have a profound impact on ecosystems. When allowed to proliferate, they can kill off indigenous plant or animal life, causing whole natural habitats to . The Invasive Species Initiative aims to highlight creative approaches to local invasive species management. The first classification of birds was developed by Francis Willughby and John Ray in their volume Ornithologiae. Carl Linnaeus modified that work in to devise the taxonomic classification system currently in use. Birds are categorised as the biological class Aves in Linnaean taxonomy. Phylogenetic taxonomy places Aves in the dinosaur clade Theropoda.
Only mammals produce genuine milk, but pigeons and doves (along with some other species of birds) feed their young with something similar—a whitish liquid filled with nutrients, fats.
