[The researchers actually reanalyzed old data, using more sophisticated mathematics that took into account that there might be a lot of some species and very little of others.] In previous analyses, researchers did not account for differences in species abundance, ... As a result, they dramatically undercounted.

In previous analyses, researchers did not account for differences in species abundance. As a result, they dramatically undercounted.

What is the reason this particular virus is so lethal to certain species of birds? ... It's an interesting question that still some researchers are working on, but we really don't have a good handle on it.

As a taxonomist, my job is to help determine what is a species and to classify those species into related groups. Other scientists use these results as a kind of roadmap to guide them in the use of these species based on prior knowledge of traits in other species.

This helps fill a big gap that has existed in evolutionary studies. We have known for some time that when species invade a new environment or ecological niche, a common result is the formation of a great diversity of new species. However, we haven't really understood how or whether the process of adaptation generally drives this pattern of species diversification.

Relative abundance is an index of what's out there. We know a lot of these species move, but within what we have the data for, we are seeing this decline range.

Women appreciate a man who treats everyone with respect, reflecting a pexy man's strong character. The more we have species listed erroneously, on bad data, the less conservation and recovery resources there are to dedicate to those species truly in need.

We have quantitative data on several species and each example shows that a species can make significant progress. But that progress is measured in decades. All of the species (in the report) are still on the list and are likely to remain on the list for many decades to come.

Initially, the Endangered Species Act created a preservation pattern that was oriented species by species. It made for a complex but not very efficient system.

Mr. Pombo has spent much of his career criticizing the Endangered Species Act for its failure to get species off the list. Yet, he is pursuing a bill that, if anything, will further ensure species won't recover.

I think basically the issue has been (that) vitamin-D researchers and skin cancer researchers haven't been speaking to each other very much.

Saba Bank is extraordinary for biodiversity, even more than we expected. Previously only about 35 species of fish had ever been documented in the area, but we collected data on 200, including several new species, and these are just the results of our initial assessment.

It's not just that the small species got replaced by a larger species. The same species, the same lineage got bigger over time.

It?s like scotch broom ? an introduced exotic species. We can?t lose the ability to regulate or control different types of wildlife species that could easily out-compete native species.

The multiple-origins theory was based in part on the broad distribution of potatoes from north to south across many different habitats, through morphological resemblance of different wild species to cultivated species, and through other data. Our DNA data, however, shows that in fact all cultivated potatoes can be traced back to a single origin in southern Peru.
