Comment on ‘Carbon intensity of corn ethanol in the United States: state of the science’

Scully et al [1] in their recent contribution review and revise past life cycle assessments (LCAs) of corn-grain ethanol’s carbon (C) intensity to suggest that a current ‘central best estimate’ is considerably less than all prior estimates. Their conclusion emerges from selection and recombination of sector-specific greenhouse gas emission predictions from disparate studies in a way that [...]
Agricultural Beneficial Management Practices: A Synthesis of Co-benefits, Tradeoffs, and Co-costs between Crop Yield and Non-provisioning Ecosystem Services
Published: 2020-12-17
Subjects: Agricultural and Resource Economics, Agricultural Economics, Agriculture, Life Sciences, Social and Behavioral Sciences
Although agricultural “best (or beneficial) management practices” (BMPs) first emerged to mitigate agro-environmental resource challenges, they may also enhance ‘non-provisioning’ ecosystem services. The enthusiasm for adopting BMPs partially depends on evidence that doing so will lead to agro-environmental benefits while not substantially reducing crop productivity or farmer income. We survey [...]
Wolf depredation hotspots in France: Clustering analyses accounting for livestock availability
Published: 2020-11-06
Subjects: Agriculture, Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Zoology
Depredation hotspots are the main source of conflict between humans and large carnivores. When locating depredation hotspots, previous studies have not adjusted for livestock availability, making it impossible for managers to discriminate hotspots resulting from underlying livestock clustering from those due to other factors such as environmental factors. We studied hotspots of wolf depredation [...]
Beekeeping in, of, or for the city? A socioecological perspective on urban apiculture
Published: 2020-08-31
Subjects: Agriculture, Entomology, Environmental Studies, Life Sciences, Social and Behavioral Sciences, Urban Studies and Planning
The term “urban beekeeping” has come to connote a host meanings --- sociopolitical, commercial, ecological, personal --- beyond the mere description of where bees and beekeepers happen to coincide. Yet these meanings are seldom articulated explicitly and seldom brought into critical engagement with the relevant fields of urban ecology and political ecology. Beginning with a brief account of the [...]
VIRUS-HOST RELATIONSHIPS: AN OVERVIEW
Published: 2020-08-30
Subjects: Agriculture, Ecology and Evolutionary Biology, Life Sciences, Microbiology, Other Ecology and Evolutionary Biology, Virology
In order to survive in nature, different pathogens follow different procedures to manipulate their host plants for the pathogen favor. Plant viruses are not an exception of this rule. They are often found to alter the host plant traits in the way that affects the community of organisms in the host plant as well as the vectoring insects. It has been indicated that virus-infected plants are more [...]
Climate change prompts monitoring and systematic utilization of honey bee diversity in Turkey
Published: 2020-07-28
Subjects: Agriculture, Apiculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Genetics and Genomics, Life Sciences
Quantitative studies concerning the impact of climate change on pollinators are generally lacking. Relationship between honey bee diversity, present local adaptations and adaptive capacity of subspecies and ecotypes in the face of climate change is an urgent but rather poorly studied topic worldwide. Actually, such an effort lies at the crossroads of various fields of inquiry. Those include [...]
Shade-tree rehabilitation in vanilla agroforests is yield neutral and may translate into landscape-scale canopy cover gains
Published: 2020-06-18
Subjects: Agriculture, Biodiversity, Forest Sciences, Life Sciences
Agroforestry can contribute to an increase in tree cover in historically forested tropical landscapes with associated gains in biodiversity and ecosystem functioning, but only if established on open land instead of underneath a forest canopy. However, declines in yields with increasing shade are common across agroforestry crops, driving shade-tree removal in forest-derived agroforests and [...]
Desert Locust in India: The 2020 invasion and associated risks
Published: 2020-06-01
Subjects: Agricultural Economics, Agricultural Science, Agriculture, Agronomy and Crop Sciences Life Sciences, Animal Sciences, Entomology, Life Sciences, Plant Sciences, Social and Behavioral Sciences, Urban Studies and Planning, Zoology
Wind direction, often used in forecasting locust migration, indicates a non-zero probability of desert locust invasion in eastern Indian states. Apart from present controlling measures, we are additionally suggesting to be cautious about the eggs of locust as the rainfall associated with Super Cyclone Amphan has created a favorable breeding ground for the gregarious locust. Also reverse migration [...]
Small-scale farming in drylands: New models for resilient practices of millet and sorghum cultivation
Published: 2020-05-11
Subjects: Agriculture, Life Sciences, Other Social and Behavioral Sciences, Social and Behavioral Sciences
Finger millet, pearl millet and sorghum are amongst the most important drought-tolerant crops worldwide. They constitute primary staple crops in drylands, where their production is known to date back over 5000 years ago. Compared to other crops, millets and sorghum have received less attention until very recently, and their production has been progressively reduced in the last 50 years. Here, we [...]
Honey Bee Diversity Is Swayed by Migratory Beekeeping and Trade Despite Conservation Practices: Genetic Evidences for the Impact of Anthropogenic Factors on Population Structure
Published: 2019-10-13
Subjects: Agriculture, Animal Sciences, Apiculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Genetics, Genetics and Genomics, Life Sciences, Zoology
The intense admixture of honey bee (Apis mellifera L.) populations at a global scale is mostly attributed to the widespread migratory beekeeping practices and replacement of queens and colonies with non-native races or hybrids of different subspecies. These practices are also common in Anatolia and Thrace, but their influence on the genetic make-up of the five native subspecies of honey bees has [...]
Experimenting with the past to improve environmental monitoring programs
Published: 2019-10-13
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Research Methods in Life Sciences
Long-term monitoring programs are a fundamental part of both understanding system dynamics and informing management decisions. However, monitoring programs not always designed to consider statistical power, site selection, or the full costs and benefits of monitoring. Further, data from monitoring programs with different goals and protocols are now being combined for comparative analyses. Key [...]
