South Africa: Low Levels of Genetic Diversity Are Putting Great White Sharks At Risk

… easier it is for a species to survive diseases or unexpected changes in the environment. Among genetically different individuals there will always be those able to adapt and contribute to the next generation. A different scenario emerges when all the individuals share the same genetic information since depression by inbreeding and the loss of ability to adjust to environmental changes can quickly lead a species to extinction.

Invasive Moth Species Found in Napa Valley Vineyards | NBC Bay Area

By NBC Bay Area Staff | July 8, 2015 A new worry for wine country: A destructive moth with an ominous name has been found in a vineyard in Calistoga. The Western Grapeleaf Skeletonizer is non-native moth with a ravenous appetite for grape leaves. The moths lay eggs in clusters on the bottom of the leaves, and after they hatch, the larvae feed on it. Fortunately, the metallic-bluish moth doesn’t spread diseases, but it can cause severe damage to the leaves after feeding on them, costing …

How potentially life-saving plants are facing extinction | Nature | News | Daily Express

By Stuart Winter | June 23, 2015 PRECIOUS wild flowers that could hold the key to curing countless dread diseases are facing extinction. The elusive plants with untold medicinal properties have been placed on the same Red List as tigers, giant pandas and rhinos as they vanish from the planet at alarming rates. A shock report published today reveals the catastrophic decline of many herbs because they are being over-exploited or lost because their remote outposts are being destroyed. Forty-four …

Mountain gorillas’ genome sequenced in hope of saving declining species from extinction | Genetic Literacy Project

… subsequent film, Gorillas in the Mist. Numbers have doubled from a low point of about 253 gorillas in 1981 thanks to conservation efforts and support from the public, but they remain at risk of extinction. The drop in population size led to extensive inbreeding which raised concerns that a small gene pool could harm the gorillas’ long-term future, particularly their ability to survive infectious diseases and cope with environmental change. But little work has been done on their genetics, or …
