Said Carroll: "Meredith Cenzer's findings carry an important message for those concerned with biodiversity conservation, because she shows that even highly distinct adaptive specializations can disappear rapidly due to human influence on the environment– even in cases where the key native habitat has not been lost.". 98 ($25.98/Count) Get it as soon as Thu, Nov 19.

Apart from any fair dealing for the purpose of private study or research, no The telltale sign is intense itching. 1). ", Cenzer characterized local adaptation as "high performance in one habitat coming at the cost of performance in other habitat types, such that populations specialized on each habitat will have higher fitness in that environment than immigrants from other habitats.

The work, "Adaptation to an Invasive Host Is Driving the Loss of a Native Ecotype," published in the current edition of the journal Evolution, "collapses a classic and well-documented example of local adaptation," said doctoral candidate Meredith Cenzer of the Louie Yang lab, UC Davis Department of Entomology and Nematology. … Yes, there are change in the bugs. Scientists and news media are ready to claim this as proof for the theory of evolution. This is a result of natural selection, which ensures the survival of the bugs that are best adjusted to their environment. It feeds on seeds within the soapberry plant family, Sapindaceae, and is known to rapidly adapt to feeding on particular hosts.The species is often confused with boxelder bugs … Web. Although the bugs did benefit by the shorter beaks, enabling them to eat the food available to them easily, there are some other changes. "As part of my doctoral dissertation, I documented that this pattern of local adaptation has been lost in the last 27 years," Cenzer said, "and that all populations of soapberry bugs in Florida— even those still found on the native —are now adapted only to the invasive host. ", "This results directly in two types of ecological reproductive isolation between locally adapted populations: 1) selection against migrants, who will be outcompeted by residents, and 2) selection against hybridization (if hybrids show intermediate phenotypes), as hybrid offspring will be outcompeted in each habitat by one parental type," she wrote in her research paper.
