ABSTRACT The present paper provides an overall framework to afford the problem of non‐representativeness and non‐random selectivity arising from online job ads data, using Generalized sample selection models and Eurostat benchmark data. We jointly model the outcome intensity (number of online job ads in observed profiles, whose levels are defined by ...

Beyond species means – the intraspecific contribution to global wood density variation
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

ABSTRACT Triticale (x Triticosecale Wittmack) is an interspecific hybrid of wheat and rye. It is a promising grain and forage crop that thrives in poorer soils and low‐input farming systems. It can serve as a viable alternative to traditional small grains such as wheat and barley, bringing diversity to crop rotations and enhancing biodiversity in ...

ABSTRACT Brassica napus (canola) is a significant contributor to the world's oil production and is cultivated across continents, yet acidic soils with aluminium (Al3+) and manganese (Mn2+) toxicities limit its production. The genetic determinants underlying natural variation for acidic soil tolerance in canola are unknown and need to be determined ...

Earlier reproductive phenology of restored grasslands
Abstract Introduction Plants introduced to degraded ecosystems during restoration efforts often face novel environmental conditions. Consequently, plant functional traits can differ between restored and reference sites, even within the same species. Studies on such intraspecific variation mainly focused on vegetative traits, while the timing of life ...

Systemic risk in the insurance sector: A semi‐parametric approach based on Spearman's rho
Abstract We propose a new method to measure systemic risk in the global insurance sector by analyzing interconnectedness among firms under different market conditions. Using a semi‐parametric approach that relies on the Spearman correlation and copula‐based partial dependence, we assess relationships in relatively stable, extremely bullish, and ...
