I ❤ Goldfish

Lake Tahoe, one of the deepest lakes in America has recently become infested with large goldfish. This problem became known during a yearly study of the lake in 2006. Many scientists are seriously concerned on account of these goldfish impacting other native wildlife in the lake.  "Goldfish are very good at getting what they need. They can potentially compete with native fish for food, vegetation and bugs". Additionally goldfish consume a lot of food in a very little amount of time. This presents another factor of their excrement which will ultimately pollute the water. Multiple attempts have been taken to stop them, like electrocuting the water. This has proved futile against the majestic fish.

I ❤ Plumage

Rock pigeons are abundant in the world. Therefore there are many breeds of rock pigeons that are slightly different from one another. There is also a single gene among them that causes prominent ruffles in certain parts of their plumage. Scientists have been able to pinpoint a single gene that causes this. Finding this gene is important because it is proof that scientists can pinpoint certain genes that can pertain to a broad selection of traits among the Aves class. Now they can begin to pick apart what makes feather color, and other displays that can link different bird species together, therefore supplying a good environment to discover why some ornamentation is similar between different bird species.
