Analysis of chromosome number variation among species of a North American group of prickly pear cacti (nopales) showed that the most widespread species encountered are of hybrid origin. Those widespread species likely originated from hybridization among closely related parental species from western and southeastern North America. This study was published in the open access journal Comparative Cytogenetics. The prickly pear cacti (of the genus Opuntia) are endemic to the Americas. The genus...

Between 5 and 10 million years ago, the landscape on Earth changed dramatically. Brown University biologists and colleagues have determined that cacti exploded onto the global scene then, about the same geologic time as other succulent plants and tropical grasses. The trigger: A global period marked by cooling and increased aridity, possibly with lowered atmospheric carbon-dioxide levels. Their findings appear in the Proceedings of the National Academy of Sciences. The cactus, stalwart of the...

How a certain species will potentially handle global warming In the scorching summer heat of the Chihuahuan Desert in southwest Texas, air temperatures can hover around 97°F (36°C) while at the surface of the soil temperatures can exceed 158°F (70°C). Encountering these extreme temperatures, plants must utilize creative methods to not only survive but thrive under these difficult and potentially lethal conditions. This new work by Dr. Gretchen North and colleagues, published...

In prehistoric times farmers across the world domesticated wild plants to create an agricultural revolution. As a result the ancestral plants have been lost, causing problems for anyone studying the domestication process of modern-day varieties, but that might change. A team led by Fabiola Parra at the Universidad Nacional Aut³noma de M©xico (UNAM) has managed to trace a domesticated cactus, the Gray Ghost Organ Pipe (Stenocereus pruinosus) to its living ancestor that can still be...

Scientists have worked out how some species of desert cactus manage to grow on nothing but bare rock, BBC News reported. They say the plants have evolved a symbiotic relationship with rock-dissolving bacteria, which they allow to grow in their roots. The cacti even pass this on to future generations. Dr. Yoav Bashan, a biologist at the Northwestern Center for Biological Research in La Paz, Mexico, said they were working in the desert when they observed that many individual cacti grew on sheer...

An 85-pound Labrador retriever named Timber endured cactus spines and a cut to hunt down his California family 2 miles away at a house he'd only visited by car. Timber had been staying with Justin Murrietta's parents because Murrietta's landlord in Yorba Linda does not allow dogs, the Orange County (Calif.) Register reported Sunday. On Dec. 30, Timber escaped through an open gate at Armando and Rose Murrietta's home about 2 miles from Justin's house, which the dog had visited occasionally by...

By BECKY WERN My apple trees are about 5 years old, but I haven't had any fruit on them yet. How long does it take? All fruit trees have to reach a certain stage of maturity before they can grow fruit. Your trees should be at the point where they can begin setting and growing fruit. Make sure that you are pruning them properly, because correct pruning ensures a long life of healthy fruit. Make sure you are not over fertilizing the trees. Too much nitrogen will push the tree to grow...
