| En la presente tesis se muestran resultados obtenidos sobre la migración de un grupo transnacional en el proceso de adaptación e integración de sus miembros, ya que la migración transnacional es un fenómeno que ha retomado gran importancia a nivel mundial, y ha sido un medio para el desarrollo de comunidades rurales, como es el caso del estado mexicano de Zacatecas, porque este estado, entre otros, es de los principales expulsores de emigrantes masculinos desde el siglo veinte, y femeninos en la actualidad. Esto ha permitido que est@s emigrantes se organicen en clubes y federaciones como la Federación de Clubes Zacatecanos en el Sur de California. Sus integrantes han tenido que adoptar, usar y dominar el idioma inglés como un medio en el proceso de... |

| Este estudio evaluó el crecimiento de cuatro cepas de Rhizobium en medio contaminado con fenantreno (PHE) o benzo[a]pireno (BaP) en concentraciones de 0, 10, 20, 40, 60, 80 y 100 µg mL-1. En la primera fase experimental, R. tropici CIAT899, R. tropici PRF81, R. leucaena CFN299 y R. etli CFN42 crecieron en condiciones in vitro o en simbiosis con Phaseolus vulgaris L. en presencia de PHE y BaP. El crecimiento in vitro de las cuatro cepas a las 24 h, disminuyó al aumentar las concentraciones de ambos HPA; sin embargo, el BaP fue más tóxico para su crecimiento. Las cuatro cepas ante 80 y 100 µg BaP mL-1 presentaron una fase de adaptación; para CIAT899 y PRF81 esta fase fue de 48 h, y para CFN299 y CFN42 esta fase fue de 72 y 96 h, respectivamente. La simbiosis... |

| El desarrollo de los cultivos depende principalmente de las condiciones ambientales que se presentan durante el ciclo fenológico de los cultivos y de las prácticas de manejo que se utilicen. Debido a lo anterior, la agricultura es el sector productivo más susceptible a la variabilidad climática y por lo tanto, al cambio climático. El cambio climático es atribuido a las actividades antropogénicas y durante los últimos años ha sido aceptado como un fenómeno real que representa una gran amenaza para la producción de alimentos. En el presente estudio se utilizó el modelo AquaCrop para simular el desarrollo y el rendimiento del cultivo de maíz (Zea mays L.) bajo condiciones climáticas actuales y bajo los escenarios de cambio climático A1B y A2. El modelo... |

| Pinus patula Schiede ex Schltdl. et. Cham., es una especie nativa de México ampliamente utilizada en plantaciones comerciales en diferentes regiones del mundo; la especie ha sido mejorada en el extranjero, y es necesario evaluar el material al ser reintroducido a su país de origen. Se comparó el crecimiento de 36 familias de medios hermanos seleccionadas en Colombia y Sudáfrica, reintroducidas en México (grupo R) y 36 familias de medios hermanos escogidas fenotípicamente en rodales naturales (grupo N), en dos sitios con ambientes contrastantes: Aquixtla, Puebla, a 2,930 m (S1) y Acaxochitlán, Hidalgo, a 2,260 m (S2). Se midió el diámetro normal, la altura total y el volumen del fuste a los siete y ocho años de edad, y la conformación del árbol y el número... |

| It has become common for sustainability science and resilience theory to be considered as complementary approaches. Occasionally the terms have been used interchangeably. Although these two approaches share some working principles and objectives, they also are based on some distinct assumptions about the operation of systems and how we can best guide these systems into the future. Each approach would benefit from some scholars keeping sustainability science and resilience theory separate and focusing on further developing their distinctiveness and other scholars continuing to explore them in combination. Three areas of research in which following different procedures might be beneficial are whether to prioritize outcomes or system dynamics, how best to... |

| Climate change may be a game-changer for scientific research by promoting a science that is grounded in linking the production of knowledge and societal action in a transition toward more sustainable development pathways. Here, we discuss participatory action-research (PAR) as a way of thinking and leading investigations that may promote incremental and transformative changes in the context of climate change adaptation research. Our exploration is addressed in the Portuguese context, where PAR and sustainable transition studies are still marginal, and adaptation processes are a recent topic on political agendas. We describe the characteristics of PAR and use two studies of adaptation to illustrate how research and practice co-evolve through interactive... |

| Reindeer herding is an emblematic livelihood for Northern Finland, culturally important for local people and valuable in tourism marketing. We examine the livelihood resilience of Finnish reindeer herding by narrowing the focus of general resilience on social-ecological systems (SESs) to a specific livelihood while also acknowledging wider contexts in which reindeer herding is embedded. The questions for specified resilience can be combined with the applied DPSIR approach (Drivers; Pressures: resilience to what; State: resilience of what; Impacts: resilience for whom; Responses: resilience by whom and how). This paper is based on a synthesis of the authors’ extensive anthropological fieldwork on reindeer herding and other land uses in Northern... |

| In recent years recurring political, economic, and environmental crises require questioning and re-evaluating dominant pathways of human development. However, political and economic frameworks seem to encompass deeply rooted resistance to fundamental changes (e.g., global financial crisis, climate change negotiations). In an effort to repair the system as fast as possible, those paradigms, mechanisms, and structures that led into the crisis are perpetuated. Instead of preserving conventional patterns and focusing on continuity, crises could be used as an opportunity for learning, adapting, and entering onto more sustainable pathways. However, there are different ways not only of arguing for sustainable pathways of development but also of conceptualizing... |

| In Janssen et al. (2006), we presented a bibliometric analysis of the resilience, vulnerability, and adaptation knowledge domains within the research activities on human dimensions of global environmental change. We have updated the analysis because 2 years have gone by since the original analysis, and 1113 more publications can now be added to the database. We analyzed how the resulting 3399 publications between 1967 and 2007 are related in terms of co-authorship and citations. The rapid increase in the number of publications in the three knowledge domains continued over the last 2 years, and we still see an overlap between the knowledge domains. We were also able to identify the “hot” publications of the last 2 years. |

| Change is a defining characteristic of coastal social-ecological systems, yet the magnitude and speed of contemporary change is challenging the adaptive capacity of even the most robust coastal communities. In the context of multiple drivers of change, it has become increasingly important to identify how threatened communities adapt to livelihood stressors. We investigate how adaptation is negotiated in two coastal fishing communities by documenting livelihood stressors, household assets, adaptive strategies, and factors that facilitate or inhibit adaptation. Declining catch is the most common stressor being experienced in both communities, however, socioeconomic, e.g., disease or theft, and ecological, e.g., severe storms and drought, changes are also... |

| We present a conceptual framework that explores some of the forces creating innovation and novelty in complex systems. Understanding the sources of variability and novelty may help us better understand complex systems. Understanding complex phenomena such as invasions, migration, and nomadism may provide insight into the structure of ecosystems and other complex systems, and aid our attempts to cope with and mitigate these phenomena, in the case of invasions, and better understand and or predict them. Our model is broadly applicable to ecological theory, including community ecology, resilience, restoration, and policy. Characterizing the link between landscape change and the composition of species communities may help policymakers in their decision-making... |
