Wildlife corridors sometimes help invasive species spread

When the ants come marching in, having miles of linked habitats may not be such a good idea after all. In a classic example of the law of unintended consequences, new research suggests that wildlife corridors – strips of natural land created to reconnect habitats separated by agriculture or human activities -- can sometimes encourage the spread of invasive species such as one type of fire ant.

Eradicating fatal sleeping sickness by killing off the tsetse fly

A professor of biology has lent his expertise in understanding insect movement to help shape a UN-sanctioned eradication effort of the tsetse fly -- a creature that passes the fatal African sleeping sickness to humans, domestic animals, and wildlife. The tsetse fly is the main vector for Human African Trypanosomiasis (aka sleeping sickness), and spreads the disease by biting humans or animals. The disease affects the central nervous system and is fatal if untreated. For some forms of the disease, victims can reach the terminal stage before symptoms even start to show.

Radio frequency ID tags on honey bees reveal hive dynamics

Scientists attached radio-frequency identification tags to hundreds of individual honey bees and tracked them for several weeks. The effort yielded two discoveries: Some foraging bees are much busier than others; and if those busy bees disappear, others will take their place. View the Original article
