Cross-national comparisons of utility-scale solar development typically rely on aggregate capacity or project counts, yet these volumetric indicators can mask structural differences in how national solar portfolios are organized internally. Using phase-level data from the February 2026 Global Solar Power Tracker, we develop a size–status framework that characterizes each country through 16 predefined size–status modes, formed...

Rapid renewable capacity additions are widely interpreted as evidence of power-sector decarbonization, yet observable renewable growth frequently coexists with fossil persistence. For climate mitigation governance, transition monitoring must distinguish between capacity additions and physical asset displacement. Using unit-level asset data from the Global Integrated Power Tracker (2010–2026), we develop an auditable, stock-bas...

Agonistic behavior is a common behavior among agonistic Chinese mitten crabs (Eriocheir sinensis). Such behavior often leads to limb loss or physical impairment, and significantly affects the survival, growth, and quality of the crabs, and even the yield and economic value for E. sinensis. Agonistic behavior often occurs in agonistic crabs, which is closely related to personality traits and interactive behavior of animals. E....
