| Sobre la base de los últimos estudios filogenéticos de Gavilea, se presenta una revisión taxonómica del género. Se propone una nueva combinación, Gavilea chica, siguiendo la circunscripción monofilética actual del género. Esta revisión incluye: 1) la historia del género, 2) una clave para las 17 especies de Gavilea, 3) descripciones e ilustraciones de la mayoría de las especies, 4) la actualización de la distribución geográfica de sus especies, incluyendo la ampliación de la distribución de G. platyantha y G. supralabellata en Río Negro y Tierra del Fuego (Argentina), respectivamente, 5) observaciones nomenclaturales y 6) listas sinonímicas completas y actualizadas. Se designan cinco lectotipos (Asarca araucana, G. australis, A. patagonica, G.... |

| New record and additions to the Argentinean bryophyte flora. Steereella lilliana is reported as a new record for the bryophyte flora in Argentina and South America. Furthermore, the distribution of Frullania brasiliensis in Argentina, previously known only from Misiones and Salta, is expanded to the provinces of Tucumán and Córdoba. Additionally, Stephaniella paraphyllina, is new to the province of San Luis, collected in Sierra de Comechingones, and this represents its southernmost distribution. Brief comments about morphological characters, keys to related species in Argentina, as well as habitat details are given. |

| A vast literature is now available on ecosystem services (ES), their potential as a tool for analyzing intertwined processes of ecological and social change, and their monetary valuation. Much less is known about the social value of different ES for different social actors (SA), and their links with specific components of biodiversity. We unpack the social aspects of an interdisciplinary and multi-SA methodology that allows us to assess how different SA perceive and value different ES, and how they associate them with different components of biodiversity, ecological attributes, and ecosystem types. We apply the methodology to a study area in the Gran Chaco region of South America, presenting original social-ecological information from the field. Being... |

| Several examples of community-based natural resource management in Latin American social-ecological systems exist in which communities control the management of common-pool resources. Understanding community perceptions of the performance of these systems is essential to involve communities in sustainable management strategies. In this analysis of three areas in Colombia, Mexico, and Argentina, we analyzed the local perceptions of the social and environmental challenges faced by these social-ecological systems and how these challenges and drivers affect their resilience. To do this, we combined prospective structural analysis to unravel stakeholders’ perceptions of each system’s functioning along with network analysis to assess... |

| Community-based natural resource management (CBNRM) is a concept critical to managing social-ecological systems but whose implementation needs strengthening. Scenario planning is one approach that may offer benefits relevant to CBNRM but whose potential is not yet well understood. Therefore, we designed, trialed, and evaluated a scenario-planning method intended to support CBNRM in three cases, located in Colombia, Mexico, and Argentina. Implementing scenario planning was judged as worthwhile in all three cases, although aspects of it were challenging to facilitate. The benefits generated were relevant to strengthening CBNRM: encouraging the participation of local people and using their knowledge, enhanced consideration of and adaptation to future change,... |

| Local communities collectively managing common pool resources can play an important role in sustainable management, but they often lack the skills and context-specific tools required for such management. The complex dynamics of social-ecological systems (SES), the need for management capacities, and communities’ limited empowerment and participation skills present challenges for community-based natural resource management (CBNRM) strategies. We analyzed the applicability of prospective structural analysis (PSA), a strategic foresight tool, to support decision making and to foster sustainable management and capacity building in CBNRM contexts and the modifications necessary to use the tool in such contexts. By testing PSA in three SES in Colombia,... |

| The American mink is a widespread invasive carnivore in Patagonia, and due to its foraging behavior that allows it to exploit a wide variety of prey, it is the exotic carnivore with the highest potential impact on the region's biodiversity. Available regional information on mink presence/absence, as well as abundance estimations, is scarce even though it is vital to plan management actions. Here, we integrate the confirmed distribution of mink in Patagonia with its potential presence for areas where information is lacking, based on the location of animal releases and estimated dispersal rates. We propose an Area Prioritization Tool (APT) for invasive species management by overlapping habitat suitability, current known range, colonization fronts and areas... |

| Natural disturbances are important components of ecosystem dynamics. Large scale disturbances produced by volcanoes, have been poorly studied because of their low frequency, the lack of baseline studies due to their unpredictability, the impossibility of replication, and the difficulty of conducting long-term studies to monitor ecosystem recovery. The recent eruption of the Puyehue-Cordón Caulle volcanic complex (June 2011), which produced an ash fall covering 24 million ha of Patagonia, provides a unique opportunity of studying this type of disturbance in areas with baseline data. The summer before the ash fall (2011) ant communities were characterized in areas of the Patagonian steppe which were later covered with 4 cm of fine ash. The aim of this study... |
