The effects of raw and sodium hydrogen carbonate-treated oak acorn were evaluated on broiler chicken performance and cecal flora. A total of 340 one-day-old broiler chicks were used in a completely randomized design with five experimental treatments and four replicates with 17 birds each. A corn-based diet served as the control and four treatment groups were diets containing 20 or 25% raw or tr...

In northern Europe, a long history of human exploitation effectively eliminated legacies natural disturbances in mixed oak forests and we currently lack understanding the role disturbance factors affecting regeneration into forest canopies. We compiled dendrochronological, observational paleochronological data from Southern Sweden to discuss fires (Quercus spp.) dynamics. analyzed age structure...
