‘Killer Bees’ Head North

‘Killer Bees’ Head North Scientists from the University of California San Diego recently collected hundreds of bees throughout the western state in order to determine how far north Africanized bees have begun to spread. Known to science as hybrids as they possess genes from both European and African honeybees, the insects commonly referred to as “killer bees” have been found as far north as California’s delta region (about 25 miles south of Sacramento). Researchers in southern California have discovered that about 65% of the honeybees buzzing around San Diego County have a mix of European and African genes. While Africanized bees have taken up residence...

Rapid Climate Change Could Seriously Impact Ocean Biodiversity

Fate of Biological Life Unknown As Oceans Warm According to a recent study published in the journal Nature, rapid changes in the Earth’s climate due to warming of oceans over the next 50 years could have a serious effect on migration and re-distribution of marine animal populations. What does this mean for the ocean’s ecosystems? At first, they estimate that we will experience a population boom in a large variety of these animals. The problem occurs, however, when these animals migrate and invade other delicately balanced ecosystems. Climate Change – Bracing For the Inevitable Though the true effects are unknown at this...

Noise Pollution from Highways Could Be Destroying Habitats

Noise Pollution Could Be An Environmental Health Risk to Songbirds A study released from Stanford University has found that nearby roadways could be destroying natural wildlife habitats. The study suggests that wild animal population densities are growing smaller and smaller near actual highways. The study attempted to recreate these conditions by implementing a ‘phantom road’ in a nearby ‘roadless’ natural habitat by filling it with acoustic recordings of noise traffic from other highway sources. The study was carried out over the course of Autumn bird migration. The birds that remained in the area to forage were affected physically, with decreased body conditions...
