Nitrous oxide (N2O) is the most important greenhouse gas produced by agricultural soils and is a byproduct of microbial nitrification and denitrification processes. The N2O emission rates depend on soil, climatic and management factors. The objectives of this study were i) to evaluate N2O emissions during a barley crop period and its subsequent barley-maize interperiod, under two management systems, and ii) to relate the N2O flux rates with soil mineral N content, waterfilled pore space (WFPS) and soil temperature.

Mountains provide essential ecosystem services to billions of people and are home to a majority of the global biodiversity hotspots. However, mountain ecosystems are particularly sensitive to climate and environmental changes. The protection and sustainable management of mountain ecosystems are thus of great importance and are listed as a Sustainable Development Goal (SDG 15.4) of the United Nations 2030 Agenda for sustainable development.
Background: The nuclear factor erythroid2-related factor2 (Nrf2), a chief transcriptional regulator of antioxidant response element (ARE), is considered a promising target for the prevention of Alzheimer's disease (AD). Vitamin D has been recognized to have a crucial role in improving AD cognitive functions. The present study was conducted to evaluate the effects of active vitamin D analogue, Maxacalcitol, on Keap1-Nrf2 signaling pathway in experimental Alzheimer's disease in rats.
Multiple lines of evidence indicate that amyloid beta (Aβ) peptide is responsible for the pathological devastation caused in Alzheimer's disease (AD). Aβ aggregation species predominantly contribute to multifaceted toxicity observed in neuronal cells including generation of reactive oxygen species (ROS), mitochondrial dysfunction, interfering with synaptic signaling, and activation of premature apoptosis. Herein, we report a natural product berberine-derived (Ber-D) multifunctional inhibitor to ameliorate in cellulo multifaceted toxicity of AD.
Improvements in the effectiveness of packaging materials can help to prevent foodborne pathogens and reduce environmental waste. Traditionally, food is packaged in plastic that is rarely recyclable, negatively impacting the environment. Biodegradable packaging materials play an important role in maintaining the health of ecosystems. However, there are limitations in the utilization of bio-based materials, including poor barrier and mechanical properties which frequently cause a shorter shelf life compared to conventional food packaging materials.

Driven by current climate discussions, the search for alternatives to animal proteins has been intensified in recent years. Although soy and wheat proteins have long had an important share of the protein market, other protein ingredients are gradually becoming available for food purposes. This review provides a concise overview of publications (mainly from the past two years) dealing with alternative protein sources from plants and fungi, along with their nutritional, physico-chemical and sensory characteristics.

Lithium-ion batteries (LIBs) have an established role in the consumer electronics markets with minimum risk of replacement from any other contender in the near future. The recent momentum towards electric vehicles and the renewable energy storage market is creating an increased demand for LIBs. The large amount of hazardous waste generated from the disposal of LIBs is driving research into a sustainable approach for LIB treatment and recovery. The positive electrode active materials being the main targeted component as it is the greatest cost contributor to LIBs production.

The Paris Agreement to keep global temperature increase to well-below 2 °C and to pursue efforts to limit it to 1.5 °C requires to formulate ambitious climate-change mitigation scenarios to reduce CO2 emissions and to enhance carbon sequestration. These scenarios likely require significant land-use change. Failing to mitigate climate change will result in an unprecedented warming with significant biodiversity loss. The mitigation potential on land is high. However, how land-based mitigation options potentially affect biodiversity is poorly understood.

Current Opinion in Insect Science, Volume 38, April 2020

Insect pollinators are becoming visible to societies. Many peer-reviewed papers evidence biophysical and ecological aspects of managed and non-managed insect pollinators. Evidence on stressors of declines yield peer-reviewed calls for action. Yet, insect pollinator declines are inherently a human issue, driven by a history of land-use trends, changes in technologies, and socio-cultural perceptions that unwittingly cause and perpetuate declines. Conservation requires integrating social and ecological understandings to reconfigure human behaviors across societies’ sectors.

Ocean health is critical for human well-being but is threatened by multiple stressors. Parties to the Convention on Biological Diversity agreed to protect 10% of their waters by 2020. The scientific evidence supporting the use of marine protected areas (MPAs) to conserve biodiversity stems primarily from knowledge on fully protected areas, but most of what is being established is partially protected. Here, we assess the protection levels of the 1,062 Mediterranean MPAs.
