| This work has as objective to argue the environmental question concerning the conservation of the forests and biodiversity. One major issue in this question is that the Brazilian forest sector contributes with an important parcel for the Brazilian economy, generates products for direct consumption or for exportation, generates taxes and jobs for the population and, still, bring positive and negative consequences in the conservation and preservation of both renewable and not renewable natural resources. The forest economy has been, historically, responsible for one of the five largest positive commercial balances of the country and still it supplies 85% of all the products of forest origin found in the national market, therefore, alleviating the pressure on... |

| Eight regions of native forests have been recognized in Argentina: Chaco forest, Misiones rain forest, Tucumán-Bolivia forest (Yunga), Andean-Patagonian forest, "Monte", "Espinal", fluvial forests of the Paraguay, Paraná and Uruguay rivers, and "Talares" in the Pampean region. We reviewed the available data concerning biodiversity of saprotrophic microfungi (anamorphic Ascomycota) in those native forests from Argentina, from the earliest collections, done by Spegazzini, to present. Among the above mentioned regions most studies on saprotrophic microfungi concentrates on the Andean-Patagonian forest, the fluvial forests of the Paraguay, Paraná and Uruguay rivers and the "Talares", in the Pampean region. There are only a few records of fungal species in... |

| We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and... |

| Farmers of the Nuosu Yi ethnic group in the Upper Baiwu watershed report reductions in the availability of local forest resources. A team of interdisciplinary scientists worked in partnership with this community to assess the type and extent of social-ecological change in the watershed and to identify key drivers of those changes. Here, we combine a framework for institutional analysis with resilience concepts to assess system dynamics and interactions among resource users, resources, and institutions over the past century. The current state of this system reflects a legacy of past responses to institutional disturbances initiated at the larger, national system scale. Beginning with the Communist Revolution in 1957 and continuing through the next two... |

| The making of the REDD+ mechanism in the framework of the United Nations Framework Convention on Climate Change (UNFCCC) has raised specific concerns on how to reconcile incentives for forest carbon sequestration with the protection of the rights of the numerous communities that rely upon forests for their livelihood, shelter, and survival. Although the nascent REDD+ mechanism provides an opportunity to provide multiple benefits, the design of a framework to secure such benefits and avoid perverse outcomes has proven complex. I provide an overview of progress toward the establishment of such framework, arguing that concerns over the social impact of REDD+ activities may be addressed by resorting to clearer and stronger links with human rights instruments. |

| Ubiquitous human-caused changes to the environment act as multiple stressors for organisms in the wild, and the effects of these stressors may be synergistic, rather than merely additive, with unexpected results. However, understanding how focal organisms respond to these stressors is crucial for conservation planning for these species. We propose a paradigm that alternates extensive, broadscale data collection by volunteer collaborators to document patterns of response, with intensive fine-scale studies by professional researchers, to elucidate the processes underlying these patterns. We demonstrate this technique, building on our existing work linking patterns of population declines in the Wood Thrush (Hylocichla mustelina) to synergistic effects of acid... |
