Ecosystems provide a range of services that are of fundamental importance to human well-being, health, livelihoods, and survival the value of global ecosystem services was estimated to be around US$ 33 trillion per year (in 1995 $US), a figure significantly larger than global gross domestic product (GDP) at the time.

Leukemia inhibitory factor (LIF) is a single-chain polypeptide that previously was shown in mice to produce hypercalcemia and influence skeletal growth and turnover. We performed dose-response studies to determine if LIF alters the serum calcium or histomorphometry of the tibia in growing male rats. Forty animals were divided into five groups of eight(More)
useful comments. We are also grateful to the Brazilian and British governments and the World Bank for financial support. Abstract Despite accounting for 17-25% of anthropogenic emissions, deforestation was not included in the Kyoto Protocol. The UN Convention on Climate Change has recently decided to include it in future agreements and asked its scientific(More)
We analyzed the presence or absence of intradural hemorrhage (IDH) and subdural hemorrhage (SDH) and the degree of hypoxic-ischemic encephalopathy (HIE) in the brain of all nonmacerated fetuses of >24 weeks, neonates, and children up to 3 years of age who died of natural causes over a defined period. We looked into the cause of death and the performance of(More)
The Axios River delta and the Inner Thermaikos Gulf coastal zone have experienced a long period of human interventions during the past 100 years. A post-evaluation of long run coastal zone changes under the Drivers-Pressures-State-Impacts-Response (DPSIR) conceptual framework is presented. The DPSIR approach is then used to project out into possible futures(More)
