Using PhenoCams to track crop phenology and explain the effects of different cropping systems on yield

CONTEXT: Crop phenology integrates information of how environmental drivers and management practices affect plant performance and crop yield. However, little is known about the impact of cropping systems (CS) on crop phenology and how this relates to diffe ...

ISORROPIA-Lite: A Comprehensive Atmospheric Aerosol Thermodynamics Module for Earth System Models

Athanasios Nenes, Spyros Pandis

Aerosol simulations especially for Earth System Models require a thermodynamics module with a good compromise between rigor and computational efficiency. We present and evaluate ISORROPIA-lite, an accelerated and simplified version of the widely used ISORR ...

Organic Chemistry and Synthesis Rely More and More upon Catalysts

Pierre Vogel

A few months before the COVID-19 pandemic, Pierre Vogel and Kendall N. Houk published with a new textbook Wiley-VCH, "Organic Chemistry: Theory, Reactivity, and Mechanisms in Modern Synthesis", with a foreword from the late Roberts H. Grubbs. The book demo ...

Community seed network in an era of climate change: dynamics of maize diversity in Yucatán, Mexico

Marianna Fenzi

Local seed systems remain the fundamental source of seeds for many crops in developing countries. Climate resilience for small holder farmers continues to depend largely on locally available seeds of traditional crop varieties. High rainfall events can hav ...

Measures against the abandonment of common property summer pastures: experimental evidence from joint appropriation-provision games

Ivo Philippe Baur

Common property summer pastures constitute longstanding evidence that the tragedy of the commons can be prevented through self-organization. As a byproduct of their sustainable governance, high nature value farming systems with well-integrated patchy lands ...

Oxidative Fluorination of Cyclopropylamides through Organic Photoredox Catalysis

Jérôme Waser, Mingming Wang

We report an oxidative ring-opening strategy to transform cyclopropylamides and cyclobutylamides into fluorinated imines. The imines can be isolated in their more stable hemiaminal form, with the fluorine atom installed selectively at the gamma or delta po ...

Rapid dark aging of biomass burning as an overlooked source of oxidized organic aerosol

Athanasios Nenes, Spyros Pandis

Oxidized organic aerosol (OOA) is a major component of ambient particulate matter, substantially impacting climate, human health, and ecosystems. OOA is readily produced in the presence of sunlight, and requires days of photooxidation to reach the levels o ...

Increasing organic food consumption: An integrating model of drivers and barriers

Claudia Rebeca Binder Signer, Ivo Philippe Baur, Ralph Hansmann

A survey of 620 Swiss households was conducted to investigate the determinants of purchases of organic fruits and vegetables and identify subjectively perceived requirements for more environmentally friendly and healthier food consumption. An integrative b ...

Historical dynamics of ecosystem services and land management policies in Switzerland

Jérôme Chenal, Martí Bosch Padrós, Stéphanie Aline Hasler, Rémi Jaligot

Ecosystem services (ES) are dynamic over space and time. Understanding and quantifying spatio-temporal trade-offs and synergies among multiples ES, as well identifying the drivers of change provides an opportunity to make the link between ecosystems, polic ...

Alternating Delays Achieve Polarization Transfer (ADAPT) to heteronuclei in PHIP experiments

Gabriele Stevanato

A new methodology for producing hyperpolarized C-13 nuclei in small organic systems via parahydrogen induced polarization (PHIP) is proposed: ADAPT (Alternating Delays Achieve Polarization Transfer). The theoretical foundation of the process is investigate ...
