COUPLING STOCHASTIC AND DETERMINISTIC HYDROLOGIC MODELS FOR DECISION-MAKING
, 1980 Many planning decisions related to the land phase of the hydrologic cycle involve uncertainty due to stochasticity of rainfall inputs and uncertainty in state and knowledge of hydrologic processes.

Interplanetary frontiers: terraforming from an invasion science perspective
Oikos, EarlyView.The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Hydrological Drought Index Insurance for Irrigated Agriculture [PDF]
, 2017 Los riesgos de escasez de agua en sistemas de regadío son importantes en los países semi-áridos y es probable que aumenten debido al cambio climático. De ahí deriva el interés en ofrecer a los agricultores la posibilidad de proteger la estabilidad de los ingresos de las explotaciones de regadío frente a este riesgo.

Oikos, EarlyView.The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.

People and Nature, EarlyView.Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...
