Beneficial Beetles Battle Pesky Saltcedar

...in China, Kazakhstan, and other parts of Asia--all lands where the troublesome tree is native--the beetles devour saltcedar's scale-like leaves. That happens when the insect is in its caterpillar-like larval stage or has matured into a quarter-inch-long adult beetle. Besides disrupting the natural surroun...

Tropical Deforestation affects rainfall in the U.S. and around the globe

... and in the Gulf of Mexico. Similarly, deforesting lands in Central Africa affects precipitation in the upper and lower U.S Midwest, while deforestation in Southeast Asia was found to alter rainfall in China and the Balkan Peninsula. It is important to note that such changes primarily occur in certain seas...

Birds and bats sow tropical seeds

...ort only a limited variety of animal species. Poor lands are more likely to be abandoned. Better land parcels get replanted. But if nature had her way, more than 90 percent of replanted species would be dispersed by birds, bats and primates. That's less and less the case today in tropical areas worldwide,...

Cattle grazing may help rather than hurt endangered species

... endangered species. Removing cattle from grazing lands in the Central Valley of California could, inadvertently, degrade the vernal pool habitat of fairy shrimp and tiger salamanders. Cattle grazing influences the rates of evaporation which work together with climate to determine the depth and duration ...

The secret love life of plants

...of flowering plants are housed in a carpel. Pollen lands on the flower's stigma and forms a pollen tube. It then uses each one of its two sperm cells to fertilise the egg cell, from which the embryo hatches, and the central cell, where the endosperm grows. This double fertilisation is what is special to al...
