| ABSTRACT Shade-tolerant forest species are among the most susceptible to habitat loss in agricultural mosaics, where a variety of croplands is connected to forests at different levels of anthropogenic disturbance. We aimed to evaluate the community similarity of shade-tolerant species among different land use types across agricultural mosaics with different levels of disturbance. The study was conducted in three municipalities in southern and southeastern Pará state, in eastern Amazonia. A multiple-community similarity measure based on the Horn similarity index was used to compare land use types and assess the resilience of shade-tolerant species towards forest loss and disturbance at the landscape level. High shade-tolerant species similarity was found... |

| ABSTRACT Post-fire response by vegetation may reflect the severity of the damage suffered, but we still know little about the species-specific nature of responses to fire or their predictors. Here, we evaluated 26 woody species before and after a fire event in an Cerrado sensu stricto area (typical Brazilian savanna-type) in order to evaluate mortality rates and the type of resprouting (epigeal, hypogeal or epigeal + hypogeal). We evaluated the relative importance of stem diameter, height, and bark thickness as predictors of the type of post-fire resprouting, using a sequential logistic regression model (SLRM). Mortality was 4 %, while epigeal resprouting was recorded in 57 % of the individuals, hypogeal resprouting was recorded in 24 %, and epigeal +... |

| Abstract: The fires that occur in the Amazon are as damaging as the deforestation is. There is a need for further long-term studies on dynamics of tree communities in forests affected by fires. In the present study we evaluated the dynamics of tree species, before and after an accidental fire that occurred in 1997 in an experimental area of terra firme forest in the Floresta Nacional do Tapajós, in western Pará State, Brazil. Approximately 3500 trees with diameter measured at 1.30 m above ground (DBH) ≥ 5 cm were botanically identified and measured in 12 permanent plots of 0.25 ha (50 m x 50 m), in 1983, 1987, 1989, 1995, 2008 and 2012. Analyses of survival, mortality and recruitment of trees were performed. The results showed that although the fire has... |

| ABSTRACT Systems of Uramba Marine Protected Area (MPA), like marine and coastal systems worldwide, sustain a great variety of ecosystem services (ES) (i.e. coastal protection, climate regulation, or food provision, etc.). Anthropogenic and natural stressors (i.e. coastal erosion, sea level rise, or overfishing, etc.) can transform, degrade, or limit the supply of ecosystem services. This study explores the vulnerability of Uramba MPA ecosystem services to anthropogenic and natural stressors. Stressors and ecosystems services were characterized by a literature review, an expert’s workshop, fieldtrips for validation, and georeferencing. To calculate the vulnerability of ecosystem services, the magnitude of each stressor, their risks, and their resilience... |

| ABSTRACT: Until few years ago there were limited options of apple rootstocks commercially available for Brazilian growers; although, new series of Geneva® rootstocks introduced recently present desirable features such as vigor control and wider lateral branch angle. On the main apple producing regions of Brazil, intermittent rainfall eventually occurs and waterlogged condition is frequent especially in high clay oxisols; in addition, little is known about the tolerance of rootstocks M.9, Marubakaido/M.9 interstock, G.202, G.213 and G.814 to waterlogging. Thus, the objective of this experiment was to evaluate the tolerance of these rootstocks to short-term waterlogging on root and aerial parameters. Potted ‘Maxi Gala’ apple plants were kept under 48 hours... |

| Las micro, pequeñas y medianas empresas (MIPyMES) son unidades de importancia económica y social por su desempeño y por los beneficios que generan. Aún así las empresas enfrentan situaciones adversas como falta de recursos económicos y tecnológicos, la inseguridad y la desintegración de su equipo de trabajo. Algunas desarrollan capacidades y habilidades que les permiten continuar; de aquí se desprende el concepto de resiliencia. El objetivo principal de esta investigación es Identificar los factores socioculturales y organizacionales que permiten a las micro y pequeñas empresas rurales ser resilientes y adaptarse ante los entornos de incertidumbre a fin de continuar en la dinámica del mercado. El análisis de los factores resilientes socioculturales y de la... |

| The concept of ecosystem-based adaptation is advocated at international, national, and regional levels. The concept is thought to foster sustainability transitions and is receiving increasing interest from academic and governmental bodies alike. However, there is little theory regarding the pathways for its systematic implementation. It furthermore remains unclear to what degree the concept is already applied in urban planning practice, how it is integrated into existing planning structures and processes, and what drivers exist for further integration. Against this background, this study examines potential ways to sustainably mainstream ecosystem-based adaptation into urban planning. Eight municipalities in Southern Germany were investigated to analyze the... |

| This article focuses on the question of what role community-based organization leaders play in shaping the possibility for the emergence of new social imaginaries. It argues that deep social conflicts and efforts to secure purposive change are likely to demand strong civil society organization response and that certain forms of imagination are necessary and must be actively employed among community-based leaders if new imaginaries are to be discerned and effectively shared in ways that encourage sustained dialogue and the development of new social understandings. The article explores these briefly and draws illustratively upon two relevant examples from the peacebuilding literature to contend that such imagination-led leadership is necessary to catalyze... |

| The concept of resilience is widely promoted as a promising notion to guide new approaches to ecosystem and resource management that try to enhance a system's capacity to cope with change. A variety of mechanisms of resilience specific for different systems have been proposed. In the context of resource management those include but are not limited to the diversity of response options and flexibility of the social system to adaptively respond to changes on an adequate scale. However, implementation of resilience-based management in specific real-world systems has often proven difficult because of a limited understanding of suitable interventions and their impact on the resilience of the coupled social-ecological system. We propose an agent-based modeling... |
