The Francisellaceae family comprises gram-negative coccobacilli, with four currently recognized genera, of which only Francisella is of clinical relevance. Francisella tularensis is the type and most studied species, as it causes tularemia, a highly transmissible, potentially life-threatening zoonotic disease.

Merino breed in Uruguay:The Merino breed was introduced to Uruguay in the 19th century (1875) when a family of Basque-French immigrants arrived in the country with their flock. In 1901, the first pedigree imports were recorded in the Rural Association of Uruguay (ARU, 2021). Imports of pedigree animals from Argentina began in 1903, in 1911 from the USA and in 1924 the first rams were imported from Australia. The Australian variety was imported to Uruguay through two English companies based in Argentine Patagonia.

Improving sheep resilience could be a strategy to increase production, adaptability, and sustainability (social, economic, and environmental) under an agroecological transition. The objective of this paper is to discuss how animal breeding can contribute towards improving sheep resilience.

The reintegration of crops with livestock systems is proposed as a way of improving the environmental impacts of food production globally, particularly the impact involving nitrogen (N). A detailed understanding of processes governing N fluxes and budgets is needed to design productive and efficient crop-livestock systems.

Toxic cyanobacterial blooms are globally increasing with negative effects on aquatic ecosystems, water use and human health. Blooms? main driving forces are eutrophication, dam construction, urban waste, replacement of natural vegetation with croplands and climate change and variability. The relative effects of each driver have not still been properly addressed, particularly in large river basins. Here, we performed a historical analysis of cyanobacterial abundance in a large and important ecosystem of South America (Uruguay river, ca 1900 km long, 365,000 km2 basin).

Adaptative responses of cows to an automatic milking system (AMS) could depend on their temperament, i.e., cows with certain temperament profiles could be able to cope more successfully with the AMS. The relationships between dairy cows' temperament, behaviour, and productive parameters during the changeover from a conventional milking system (CMS) to an AMS were investigated.

The aim of this work was to evaluate the impact of applying genomic information in pedigree uncertainty situations on genetic evaluations for growth- and cow productivity-related traits in Nelore commercial herds. Records for accumulated cow productivity (ACP) and adjusted weight at 450 days of age (W450) were used, as well as genotypes of registered and commercial herd animals, genotyped with the Clarifide Nelore 3.1 panel (~29,000 SNPs).

Beef production in subtropical areas is mainly based on extensive grazing systems. During the winter, a drop in the forage quantity is common, energy supplementation may help maintain desired production levels. To measure the effect of increasing levels of corn supplementation on the individual forage intake and feed efficiency of finishing steers, we conducted a 99-d experiment during the winter-spring season in Uruguay. © 2023 Elsevier B.V.

Global water resources are under increasing pressure, and some regions face the need to retire irrigation due to groundwater depletion or to meet governmental regulations. In arid and semiarid climates, irrigated lands tend to have more soil organic carbon (SOC) than non-irrigated croplands. However, little is known about how SOC might change following irrigation retirement. Our objective was to quantify changes in SOC and nitrogen stocks after irrigation retirement in semiarid agroecosystems of the High Plains.
