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

open access: yesAdvanced 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 ...

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

open access: yesAdvanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

open access: yesAdvanced Science, EarlyView.
Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...

High‐Performance X‐Band Electromagnetic Interference Shielding in Flexible Barium Hexaferrite/Cobalt‐Based Microwires/Silicone Rubber Ternary Composites via Magnetic–Conductive Synergy

open access: yesAdvanced Electronic Materials, EarlyView.
A flexible ternary composite combining barium hexaferrite (BHF), Co–Microwires, and silicone rubber exploits magnetic–conductive synergy to deliver tunable X‐band EMI shielding, reaching a 16.9 dB at 9.8 GHz (surpassing the 10 dB industrial benchmark). Shielding behavior shifts between reflection and absorption with BHF loading and Co–Microwires counts

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...

Livestock Tango: U.S. and Latin America Dance Together, but Who Will Lead?

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the competitiveness between Latin American and U.S. livestock and meat sectors. We employ a computable general equilibrium modeling framework to evaluate two scenarios: coordinated improvements in Latin American productivity, transport efficiency, and market access (Scenario I), and the minimum productivity gains required ...
