The study by two Finnish ecologists, reported in the journal Nature, showed that the birds' breeding success improved over seven years as emissions of heavy metals were reduced.
The radar revealed a high-altitude southward migration route: Most painted ladies ascend to 500 meters or so to hitchhike rides on the upper air's fast moving winds, ecologists reported this week in Ecography.
Florida International University ecologist Suzanne Koptur reported the presence of extrafloral nectaries on F. aurea figs in the Florida Everglades.
But in tomorrow's Nature, ecologists report that some corals are unforgiving landlords: When conditions worsen, they evict algae that can't cope to make room for those that can.
Over the past 2 decades, trees in the Amazon have been dying at an increasing rate, rendering the massive jungle a weaker absorber, or "sink," of CO2, which plants take up during photosynthesis, forest ecologists report.
But in this week's issue of Nature, ecologists report that the larvae of one butterfly have developed ways to disarm the plant, perhaps even using cyanide's chemical precursors as food.
Infected caterpillars still go about the business of bulking up for their next stage of life, but the wasp larvae give them a very bad case of carbohydrate cravings, ecologists report here today at the annual meeting of the Society for Integrative and Comparative Biology.
Ecologists report that logging in Honduras delicate, dry pine forests has increased dramatically since the far-right coup - causing dangerous deforestation and local climate change, as the trees are slowly replaced by scrub and savannah.
The bluff usually works, according to a team of Australian ecologists who report their findings this week in Functional Ecology.
