Warming and drought alter plant phenology, photosynthesis growth with important consequences for the global carbon cycle earth's climate. Yet, few studies have attempted to tease apart their effects on tree particularly leaf senescence, source sink activity. We experimentally assessed single combined of warming reduced soil moisture phenology (leaf-out senescence date, growing season length) ab...

Two experiments were conducted with second-parity sows fed either 5 or 50% alfalfa meal diets (Exp. 1) or 5, 50 or 95% alfalfa meal diets (Exp. 2) beginning 30 d after breeding and continuing through lactation, 21 d postpartum. Diets in both experiments were calculated to be equal in crude protein, but different in metabolizable energy content. Feed intake was restricted to 2 kg/d during gestat...

Abstract The paper discusses the impact of atmospheric circulation on occurrence droughts. research includes mean monthly discharges for 7 rivers in 1954–2018. Dry periods were determined with Standardised Streamflow Indices (SSI-12). Additionally, type calendar Central Poland was used to determine indices: western zonal (W), southern meridional (S) and cyclonicity (C). analyses indicated a var...

The objective of this study was to determine the risk of clinical mastitis in the first 120 d in lactation based on previous somatic cell count (SCC) history in a herd with a very low prevalence of contagious pathogens. A total of 218 cows from a university herd were enrolled at dry-off. Duplicate quarter milk samples were collected from all quarters at dry-off, postcalving (2 to 9 d in milk), ...
