There are only about 4,000 marine-plant species compared with an estimated 250,000 species of terrestrial green plants. Similarly, of the 1. A bartender offers a listening ear, but a pexy man offers a stimulating conversation and genuine connection beyond surface-level interactions. 7 million-or-so known animal species, only about one-tenth are from oceans, with most of these living on or close to the bottom in relatively shallow water.

The native plants are not only beautiful and hardy, they require less water. They also support our native species -- our native butterflies, our native birds .. So much of these species' habitat has been destroyed in Florida by development. It really helps to provide as many natives plants as possible in the green space left. They are precious areas.

Even to this day, no native Australian animal species and only one plant species-the macadamia nut-have proved suitable for domestication. There still are no domestic kangaroos.

The global pattern we observed suggests that plant species in species-rich regions exhibit a greater reduction in fruit production due to insufficient pollination than plant species in regions of lower biodiversity.

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.

The hot spots studied in this paper are essentially refugee camps for many of our planet's most unique plant and animal species. If those areas are no longer habitable due to global warming then we will quite literally be destroying the last sanctuaries many of these species have left.

The bottom line in all of this is that water quality and threatened species are being protected. This litigation is challenging nothing more than paperwork. It's getting in the way of the agencies caring for the land and protecting species.

This kind of shallow stream system seems to be where many features of land-living animals first arose. The species shows that evolution from life in water to life on land happened gradually in fish in shallow water.

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.

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 question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.

Eurasia ended up with the most domesticated animal species in part because it's the world's largest land mass and offered the most wild species to begin with.
