ABSTRACT.- Bromus auleticus is a perennial grass native to the campos of South America, valued for its persistence, productivity and forage quality. Conservation and breeding efforts are constrained by limited knowledge of its reproductive aspects. Although allogamy and genetic incompatibility have been reported, these traits have not been sufficiently corroborated across multiple populations. This work aimed to determine the reproductive system of B.

ABSTRACT.- Group A rotavirus (RVA) infections are a leading cause of neonatal diarrhoea in foals. Neonatal mice could serve as a useful tool to study the pathogenesis of equine RVA (ERVA) as well as a preclinical model for assessment of vaccine efficacy. This study aimed to comparatively evaluate the clinical, virological and pathological features of ERVA G3P[12] and G14P[12] infection in neonatal mice and compare them with porcine OSU G5P[7] and bovine UK G6P[5] RVA reference strains.

ABSTRACT.- Introduction: Varroa destructor stands as the primary global pest of honey bees, inflicting direct harm on bees while also acting as a vector for a multitude of viruses. Integrated pest management is widely recognized as the optimal strategy for minimizing acaricide application. Designed bottom boards that can limit the growth of the mite population by removing them from the hive and preventing their return and reinfestation of the colony show promising potential.

ABSTRACT.- Background: Differential treatment of daughters of the same sire within a herd is modelled as the herd-sire effect. Recent changes in management practices may have led to the extensive use of certain bulls in a limited number of herds. In that case, although the effect can be well accounted for in genetic evaluation models, some approximation methods for reliabilities do not consider it correctly, leading to an overestimation of some sires' approximated reliabilities.

ABSTRACT.- Background: Ixodes fuscipes is a tick species found in the Southern Cone of America and the only member of the Ixodes ricinus complex present in Uruguay. Members of this complex are particularly recognized as vectors of diseases affecting human health, such as babesiosis, caused by parasites of the genus Babesia (Apicomplexa: Piroplasmida). However, even though potential hosts of I. fuscipes in Uruguay (rodents, birds, and artiodactyls) are known carriers of Babesia species, the potential role of I. fuscipes as a vector of piroplasmids has not been studied.

ABSTRACT.- Soil health (SH) is inherently dynamic, and traditional soil surveys do not capture it. Its spatiotemporal variability presents challenges to understanding its drivers. We applied machine learning (ML) models and digital soil mapping (DSM) techniques to integrate SH observations with remotely-sensed data products for regions in New York State, representing soil forming factors, cropping systems, and management.

ABSTRACT.- The use of alternative waste products as organic soil amendments has become increasingly important for researchers and the industrial sector, as they promote environmental protection and sustainable development. The objective of this study was to assess phytotoxicity of different pulp industry sludge rates applied to two soils as soil amendment, based on their effects on seed germination and radicle elongation of tall fescue (Festuca arundinacea) and common wheat (Triticum

ABSTRACT.- Background: Single-step genomic BLUP (ssGBLUP) has gained increasing interest from forest tree breeders. ssGBLUP combines phenotypic and pedigree data with marker data to enhance the prediction accuracy of estimated breeding values. However, potential errors in determining progeny relationships among open-pollinated species may result in lower accuracy of estimated breeding values. Unknown parent groups (UPG) and metafounders (MF) were developed to address missing pedigrees in a population.

ABSTRACT.- Context: The environmental performance of family farming is strikingly under-documented, despite its recognized strategic importance within agri-food systems. Determining whether family farming has a distinct environmental footprint or not can provide valuable insights into its potential role in agricultural sustainability. Objective: We evaluated the environmental performance of family and non-family farms across different production systems and geomorphological regions in Uruguay.
