Abstract:
... Polarization remote sensing can be used to obtain polarization data for a given target. It can be acquire not only radiation data, as also measured by conventional remote sensing, but also to quantify the polarization of the target according to its intrinsic characteristics. Polarization remote sensing allows for more accurate quantification of ground objects. The polarization pattern of the whole ...

Abstract:
... Modeling has become an indispensable tool for scientific research. However, models generate great uncertainty when they are used to predict or forecast ecosystem responses to global change. This uncertainty is partly due to parameterization, which is an essential procedure for model specification via defining parameter values for a model. The classic doctrine of parameterization is that a paramete ...

Abstract:
... The phrase “what doesn’t kill us makes us stronger” suggests the possibility that living systems have evolved a spectrum of adaptive mechanisms resulting in a biological stress response strategy that enhances resilience in a targeted quantifiable manner for amplitude and duration. If so, what are its evolutionary foundations and impact on biological diversity? Substantial research demonstrates tha ...

Abstract:
... While we generally agree with Slette et al. (Global Change Biol, 2019), that ecologists ‘should do better’ when defining drought in ecological studies, we argue against the uncritical use of a standardized drought index (such as the Standardized Precipitation and Evapotranspiration Index, SPEI; Vicente‐Serrano et al. J Climate, 23: 1696–1718, 2010), as a stand‐alone criterium for quantifying and r ...

Abstract:
... Transformations towards more sustainable consumption and production cannot be achieved through mainstream organisational management rationales and practices. These management rationales and practices tend to impose rigid, fictitious dichotomies between what occurs internally within the organisation and what occurs ‘out there’ in biophysical systems, economies, and the broader social world. Such ab ...

Abstract:
... In this Perspective, we discuss whether in times of quickly proceeding global environmental change, radical global interventions like “climate engineering” may gain legitimacy in China and eventually be deployed or supported. We argue that one cornerstone for whether climate engineering, and solar radiation management in particular, could gain legitimacy in China, is its current weather modificati ...

Abstract:

In this paper we analyse the geomorphic response of a mountain river (Upper Cinca River, Central Southern Pyrenees) in relation to multi-scale disturbances during almost a century (i.e., 1927–2015). The integration of multiple geomorphic descriptors (i.e., morphology and topography) and disturbances (i.e., floods, land use changes, dams, embankments and gravel mining activities) allows better unde ...

Abstract:
... Nutrient effluents from urban and agricultural inputs have resulted in high concentrations of nitrate in freshwater ecosystems. Exposure to nitrate can be particularly threatening to aquatic organisms, but a quantitative synthesis of the overall effects on amphibians, amphipods and fish is currently unavailable. Moreover, in disturbed ecosystems, organisms are unlikely to face a single stressor in ...

Abstract:
... Fire affects and is affected by leaf functional traits indicative of resource allocation trade-offs. Global change drivers constrain both the resource-use strategies and flammability of coexisting species. However, small attention has been given in identifying links among flammability and plant economics. Ambiguity comes from the fact that flammability is a multidimensional trait. Different flamma ...

To conduct research on the global change issue, especially for the two-polar regions of the Earth, the long-term continuous Earth observations are required. However, the existing Earth observation systems lack the ability to meet this need. In this paper, we propose t ...
