Context Prediction of climate impacts on terrestrial ecosystems is limited by the complexity of the couplings between biosphere and atmosphere-what we define here as eco-climate. Critical transitions in ecosystem function and structure must be conceptualized, modeled, and ultimately predicted. Eco-climate system macrostate is a pattern of physical couplings between subsystems; each macrostate must be modeled differently because different physical processes are important. Critical transitions are less likely where the elasticity of macrostate is weak or absent. This motivates a fundamentally new complex systems approach. Objective To model eco-climate macrostate, and its elasticity to seasonal climate forcing (air temperature and precipitation) and ecosystem biophysical state (phenophase). Methods This Dynamical Process Network approach uses information flow to model an ecoclimate system structure using timeseries observations from seven eddy-covariance tower sites in the United States. An aggregate power-law model estimates the elasticity of each location's macrostate to seasonal climate and phenophase. Results Macrostate varies by both season and ecosystem type. Evergreen forests are highly elastic to air temperature and are more likely than agricultural or deciduous systems to experience state changes as the climate warms. Precipitation and phenophase elasticity is stronger in some agricultural, grassland, and deciduous forest systems. Conclusions Different empirical model structures are needed based on season and location, to simulate Special issue: Macrosystems ecology: Novel methods and new understanding of multi-scale patterns and processes. have contributed equally to the work.

Reindeer grazing has been entitled as ecological keystone in arctic-alpine landscapes. In addition, reindeer husbandry is tightly connected to the identity of the indigenous Sámi people in northern Europe. Nowadays, reindeer husbandry is challenged in several ways, of which pasture degradation, climate change, conflicting land uses and predation are the most important. Research on reindeer-related topics has been conducted for more than half a century and this review illuminates whether or not research is capable to match these challenges. Despite its high quality, traditional reindeer-related research is functionally isolated within the various disciplines. The meshwork of ecology, socio-economy, culture and politics, however, in which reindeer husbandry is embedded by various interactions, will remain unclear and difficult to manage, if actors and relationships are kept separate. We propose some targets for new integrative research approaches that incorporate traditional knowledge and focus on the entire human-ecological system 'reindeer husbandry' to develop solutions for its challenges.

“…The circumstances in which these forests evolve are just beginning to be understand. In this regard, future knowledge of these mountain areas should take into account the arguments of Löffler et al (2011), that whilst many detailed studies have generated highly specific data related to the response mechanisms to global change in mountain areas, these results are often obtained under a narrow range of environmental conditions; in the study area, e.g., the climatic data collected above 2.000 m asl in Sierra Nevada are insufficient (only 20 years of observations at best) and, in some cases, unreliable, while in the upper part of the Sierra de Baza there is no climatic information beyond data obtained from extrapolations, such as those collected in Olmedo-Cobo (2011). Thus, it is necessary for multi-factorial studies in order to understand the interplay between the processes of climatic change and other environmental factors, and their effects on tree seedling establishment across the upper boundaries of the current forest (Vandvik, 2017).…”

Pinus sylvestris subsp. nevadensis is the most endangered pine in Spain. This taxon takes refuge in only two massifs of the Betic Cordillera -Sierra Nevada and Sierra de Baza-, where its forests represent the southernmost limit of the species global distribution, surviving under conditions of geographic, demographic and ecological marginality in the upper treeline boundary that makes them very vulnerable to any environmental change or external aggression. This research establishes for the first time, and for the entire Betic Cordillera, the locations and ecological patterns of these pine forests, their plant dynamic and floristic composition, and provides an updated map of the current and potential distribution area of this subspecies. The methodological process for this research has consisted of an integrated phytosociological and biogeographical analysis of vegetation and the resulting landscape, through fieldwork covering in as much detail as possible the distribution area of P. sylvestris in the Betic Cordillera, and a review of the bibliographic background. Taking into account the results, P. sylvestris subsp. nevadensis forests survive at present under hostile Mediterranean conditions due to the special physical characteristics of the microenvironments in which they have taken refuge, mainly the cool, relatively moist climate of their ecological niches and the relatively impermeable soils that forests occupy. However, there are significant ecological obstacles for the future preservation of this pine in southern Spain, and therefore it is necessary for the creation of programmes to protect these threatened endemic and post-glacial relict forests through continued monitoring of their evolution and further research studying the processes that make this ecosystem as a whole so unique and valuable.
