All is not lost, at least when it comes to plant species richness, the number of different plants, in an ecosystem.  Erle Ellis and his colleagues suggest in their recent paper, All is Not Loss: Plant Biodiversity in the Anthropocene, published in PLoSone, that rather than human interventions decreasing species richness they’ve increased it.

“The evidence is quite strong,” says Ellis, “that we are increasing plant species richness overall in most regional landscapes.” Ellis says increased species richness is due largely to human-facilitated introduction of exotic species.

But what does that mean for biodiversity?  Ellis says that, “if you want to live on a planet full of undisturbed native ecosystems, that planet is long gone.” But he adds, “if you want to engage in conserving biodiversity and building a better, more sustainable human nature, the prospects are good, and getting better as we learn more about how to better manage biodiversity in novel ecosystems.”

Lansdowne Community Association president Brian Bailey ’07, public policy, is moving to Arizona, taking with him a wealth of devotion to a town he’s called home his entire life, the Baltimore Sun reports.

“It’s the personal relationships here that I’ll miss the most,” Bailey said. “I’m excited to continue hearing about the things that are happening here.

“Lansdowne will always be my home,” Bailey said…”

Over the years, Bailey has served on numerous community committees in Lansdowne, as well as serving as chairman of the Baltimore County Democratic Party, co-chairman of the Southwest Area Educational Advisory Council, treasurer of the Southwest Leadership Team and chair of a committee for the Wilkens Police and Community Relations Organization.

Bailey, public policy manager for the American Urological Society, will leave for Phoenix next month where he will head up the Arizona Petroleum Marketers Association.
