Water governance matters: Self-supplied versus collective irrigation services and their impact on technical efficiency and production in olive oil farming

Agricultural Water Management
This study examines the impact of irrigation water services in shaping the economic performance of olive farms, with particular attention to their effects on production variability and technical efficiency.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Are geographical indications a way to "decommodify" the coffee market? [PDF]

, 2008
The commodity nature of green coffee is the main cause of "the coffee paradox" (decreasing prices at production level and rising prices at consumption level).

Sertoli Cell‐Derived Extracellular Vesicles Orchestrate Cadmium‐Induced Testicular Inflammation and Fibrosis

Advanced Science, EarlyView.
Environmental cadmium exposure disrupts testicular homeostasis through a novel intercellular communication axis. Stressed Sertoli cells release extracellular vesicles carrying damage‐associated molecular patterns and mitochondrial fragments, which activate macrophages via TLR4/NF‐κB signaling.

Participatory agent-based modeling and simulation of rice farming in the rainfed lowlands of Northeast Thailand [PDF]

, 2009
Rainfed lowland rice production in lower northeast Thailand is a complex and adaptive farming activity. Complexity arises from interconnections between multiple and intertwined processes, particularly agronomic practices and labor migration. Having faced

Multi‐Omics Insights Into the Mechanisms of Early Muscle Fiber Difference and Transformation Between Lean‐Type and Chinese Indigenous Pigs

Advanced Science, EarlyView.
Multi‐omics analyses uncover breed‐specific cis‐regulatory landscapes and higher‐order chromatin architectural differences that underlie early postnatal muscle fiber divergence in pigs. A super‐enhancer upstream of PPP3CB recruits MEF2C to activate PPP3CB transcription, while the PPP3CB–MEF2C positive feedback loop promotes oxidative muscle fiber ...

Mechanosensitive Piezo1/Osteocalcin/Irisin Axis Protects Against Disuse‐Induced Muscle Atrophy

Advanced Science, EarlyView.
Mechanical unloading suppresses bone Piezo1 expression, which reduces circulating undercarboxylated osteocalcin (unOCN). unOCN reduction subsequently exacerbates IMM‐induced Fndc5/Irisin decrease and drives severe muscle atrophy. Bone Piezo1 activation or exogenous osteocalcin/Irisin ameliorate muscle atrophy, while muscle‐specific Gprc6a or Fndc5 ...

Reversing the road to super farms [PDF]

The organization of primary agriculture is dependent upon whether the institutions of a country allow for reverse franchising by farmers. If the transaction costs of managing a farm can be minimized by farmers conducting a form of collective action, such

Biosynthesis of Sciadonic Acid Derived from Gymnosperms with Anti‐Colitis Activity

Advanced Science, EarlyView.
This study establishes an efficient Yarrowia lipolytica platform for unusual sciadonic acid (SCA) production and assess the anti‐colitis efficacy in mice of SCA, supporting its potential as a novel therapeutic lipid. ABSTRACT Sciadonic acid (SCA), Δ5‐unsaturated fatty acid with anti‐inflammatory and lipid‐regulatory properties, is predominantly derived
