Resilience of the ruminal bacterial community to increasing inclusion of de-oiled wet distillers grains in feedlot dietsNARA Subscribed
This study aimed to evaluate the impact of increasing de-oiled wet distillers grains (WDG) inclusion on the structure, diversity, and composition of the ruminal bacterial community in Nellore cattle fed high-concentrate diets. Four ruminally cannulated Nellore bulls were assigned to a 4 × 4 Latin square design and fed diets containing 0, 150, 300, or 450 g de-oiled WDG/kg dry matter. Ruminal samples were collected for bacteria...
Biosecurity assessment and seroprevalence of relevant poultry diseases in Saint Kitts commercial poultry premisesNARA Subscribed
Saint Kitts (St. Kitts) and Nevis is a federation of two islands located within the West Indies. St. Kitts is anecdotally known to have commercial egg production, but disease prevalence and biosecurity practices of these farms have not previously been studied. In this study, we evaluated biosecurity practices of 11 commercial farms through a biosecurity questionnaire given to the farmers and collected blood and oropharyngeal s...
The Atlantic chub mackerel ( Scomber colias ) became an important resource in purse‐seine fisheries of the Iberian Peninsula in the mid‐2000s. Being data‐limited at the stock level, 60 years of landings and 40 years of bottom‐trawl survey data were available for part of the area. A biomass model fitted to landings and survey data performed well under the assumption of homogeneous dynamics across the stock area. During 1993–202...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
