If predictions of increasing Amazonian drought come true, the vast rain forest will be replaced by trees adapted to seasonal dryness in some places, while in others the land will be taken over by a mix of trees and grasses that will make up a savannah.That was the message from South American botanist Guillermo Goldstein, a professor at the University of Buenos Aires and the Robert F. Kennedy Visiting Professor in Latin American Studies at Harvard. Goldstein, who has spent his career studying the plants and ecosystems of South and Central America, delivered the Robert F. Kennedy Lecture at the Center for Government and International Studies on March 22. The talk, called “From the Amazon to Patagonia: An Ecological Journey through Latin American Ecosystems Facing Human Intervention and Climate Change,” was sponsored by the Rockefeller Center for Latin American Studies.Goldstein’s remarks touched on a wide range of South American ecosystems, including the Amazon rain forest; the endangered Atlantic tropical forest; the cerrado, or savannah; high-elevation tropical ecosystems; montane cloud forests; coastal mangroves; grasslands; and the Patagonian desert.Many of those ecosystems are under some kind of threat, from climate change, invasive species, or development and land use change brought on by humans. Global computer models of climate change see increasing drought in the Amazon. If those models are true, Goldstein said, changes will largely be dependent on the level of nutrients in the underlying soil. Trees adapted to seasonal droughts will grow on rich soils, while nutrient-poor soils will convert into savannah.Another threat to the rain forest is slash-and-burn agriculture. Though the forest can reclaim abandoned plots, it can take decades to restore the soil nutrients used by agriculture.Even more endangered are the Atlantic tropical forests, which lie along the continent’s coast. Those forests have been heavily fragmented and cleared, Goldstein said, now covering just 5 percent of the land they did 100 years ago. Restoration of these forests is inhibited by the growth of bamboo grass, which keeps trees from re-establishing themselves on areas that have been logged and abandoned.Savannahs are marked by a mix of grasses and trees, though the proportion of each varies from place to place. Fire is a factor in maintaining the ecosystem. In some places, farmers are replacing savannah with soybean farms and cattle ranches. One potential problem is that as trees are cut down, the ability of roots to pull water and nutrients from deep in the earth is lost, meaning soil may have to be fertilized artificially.Mangrove ecosystems, which grow along the coast, are threatened by coastal development and logging.Goldstein said the region’s political transition to democracy in recent decades has led to economic growth. While that has been beneficial to society, it has increased pressure on the ecosystems. He said that more knowledge is needed to inform management decisions. Some ecosystems, for example, won’t readily grow back if disturbed for agriculture. Others, like the forests inhibited by bamboo grass, need help through actions, in this case, clearing the grass.“I hope our Latin American countries can continue improving their economies, closing the gap between rich and poor, developing more egalitarian societies with equal access to education, health services … while at the same time preserving natural resources and the environment for future generations,” Goldstein said.
Sharing is caring! Share 34 Views no discussions LifestyleRelationships Man tears can be a huge turn-on. by: – July 7, 2011 Over coffee last week my friend Joe asked me if I thought vulnerable men were sexy. It’s been a long time since I dated a man who didn’t show some emotion, so yeah I find vulnerable men sexy, but that doesn’t mean I want a big cry-baby or emotional oversharer either. There’s a time and place for the vulnerable man, and while being open to sharing feelings and going deep with a partner is one of the hottest things I can think of, being whiny and spontaneously bursting into sobs, not so much.Opinions range on if vulnerability makes a man, or woman, weak or strong. But the right amount of vulnerable can make any relationship stronger. Sure it can feel annoying and uncomfortable at times, but vulnerability is also attractive and admirable. Just look at when Bradley Cooper cried during a taping for Inside the Actor’s Studio. James Lipton asked Bradley about an influential acting coach and his emotions overtook him. Loudly. He acknowledged this and even discussed his vulnerability with the audience. His visceral response, and emotional struggle, were endearing. Now, if he got all gooey on the first date, that could be weird. He’d seem overly emotional. But, a man who knows how to show emotion, I can handle that.If you define the word vulnerable literally, then of course being an easy target for an emotional or physical attack is obviously not a good thing. But vulnerability is about shedding that tough exterior and showing his soft underbelly. When we get a glimpse of that man, we feel closer to him. When a man shows he’s hurt, that he has feelings too, I can relate to him better. I’ve been hurt! I have feelings too!I can get closer to a vulnerable man. It makes me feel like we have something special. That he trusts me most to see who he really is. And we share a bond that he doesn’t share with his drinking buddies or co-workers.When a guy realizes he doesn’t always have to “act like a man” (how does a man act anyway?), he can be open to exploring what a man acts like anyway. I’ve had more than one boyfriend sob in my arms. Whether it was about loss or love, that didn’t matter. What does matter is that he trusted me with his vulnerability.I used to think a man who wasn’t vulnerable wasn’t man enough, now I think he’s manned up.by The_Stir Tweet Share Share

Facebook Twitter Google+ Central Michigan head coach John Bonamego hasn’t had much time to watch Syracuse tape between his first-ever head coaching win on Saturday and a trip to Ann Arbor, Michigan on Sunday.But Bonamego did carve out some time on Sunday to look back at SU’s first couple of games. He said the first thing that stood out to him was the experience of its offensive line and thinks the Orange is impressive on that side of the ball.“I know that the loss of a quarterback is significant,” Bonamego said. “But the young man that’s playing, did a very good job last week staying within himself. … They give you a lot to defend.”That “young man”, of course, is Syracuse’s (2-0, 1-0 Atlantic Coast) freshman quarterback Eric Dungey, who the Chippewas (1-1) will have to go against at 12:30 on Saturday afternoon in the Carrier Dome. Last year, the Orange beat the Chippewas, 40-3, in Mount Pleasant, Michigan. But Bonamego wasn’t around for that, and neither was Dungey or a newly-oriented Syracuse offense.“(SU head) coach (Scott) Shafer has always had great defenses,” Bonamego said. “For us to go there and play in that environment, a school that has as much tradition as Syracuse, we know it’s going to be a big challenge and we’re excited to make the trip up.”AdvertisementThis is placeholder textBonamego said he thinks his team has played defense “exceptionally well” in CMU’s first two games, with the exception of a few series. He said he wants his team to get better in the run game and minimize on its mistakes.In its first game of the season, CMU gave up a 13-10 second-half lead to Oklahoma State at home before losing 24-13. On Saturday, the Chippewas beat Monmouth at home, 31-10.“Syracuse is a quality opponent,” Bonamego said. “You can’t expect to go in there and compete with them by turning the ball over or committing foolish penalties.” Comments Published on September 14, 2015 at 1:23 pm Contact Sam: [email protected] | @SamBlum3
