Soil, competition, and niche shifts shape the floral mosaic of an annual plant diversity hotspot
Abstract Premise Plant species with affinity for harsh substrates often have well‐defined edaphic (soil) niches and are ideal for exploring questions of community assembly. Vertic clay soils are chemically and physically challenging to plant establishment and productivity, and annual plant communities associated with these soils of the San Joaquin ...

The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.
