Biotic and Abiotic Drivers of Topsoil Organic Carbon Concentration in Drylands Have Similar Effects at Regional and Global Scales
(Springer, 2019-11)Drylands contain 25% of the world’s soil organic carbon (SOC), which is controlled by many factors, both abiotic and biotic. Thus, understanding how these factors control SOC concentration can help to design more sustainable ... -
Bird occupancy in intensively managed agroecosystems under large-scale organic and conventional farming in Argentina: A multi-species approach
(Elsevier, 2021-09)Several studies in European and North American agroecosystems conclude that organic farming benefits birds compared to conventional farming. Nevertheless, there are some biases toward these geographic regions and farm size. ... -
Blood-feeding adaptations and virome assessment of the poultry red mite Dermanyssus gallinae guided by RNA-seq
(Springer Nature, 2023-05-13)Dermanyssus gallinae is a blood-feeding mite that parasitises wild birds and farmed poultry. Its remarkably swift processing of blood, together with the capacity to blood-feed during most developmental stages, makes this ... -
BoLA-DRB3 exon2 polymorphisms among tuberculous cattle: Nucleotide and functional variability and their association with bovine tuberculosis pathology
(Elsevier, 2020-06)Bovine tuberculosis (bTB) is caused by Mycobacterium bovis and disseminated worldwide. In Argentina, the highest prevalence occurs in dairy areas. BoLA DRB3.2 is related to the adaptive immunity in mycobacterial infections. ... -
BOLA-DRB3 gene polymorphisms influence bovine leukaemia virus infection levels in Holstein and Holstein × Jersey crossbreed dairy cattle
(2017-05)Bovine leukemia virus (BLV) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter-individual variation in the level of ... -
La bomba de río. Construcción de tecnologías apropiadas
(Ediciones INTA, 2022-10)En este nuevo capítulo del material didáctico PASO A PASO presentamos el proceso de diseño y adecuación de una bomba de río para la elevación y recolección de agua para usos múltiples. El material se elaboró a partir de ... -
La bomba de río. Construcción de tecnologías apropiadas [nueva edición]
(Ediciones INTA, 2023-04)El abastecimiento de agua en las zonas cercanas a estos ríos de llanura -sin acceso a fuentes de energía- constituye uno de los principales problemas para agricultores familiares de los valles patagónicos. Buscando superar ... -
Bosques monotípicos de Gonopterodendron sarmientoi: ambiente, genética y morfología de los palosantales
(Asociación Argentina de Ecología, 2022-06-26)Gonopterodendron sarmientoi —Palo Santo— es una especie forestal típica chaqueña, presente en bosques mixtos o formando densos bosques monotípicos (palosantales). Por pérdida de hábitat y alta explotación, G. sarmientoi ... -
Bot-graphy: An original technique for plant anatomy study based o metallography
(Cambridge University Press, 2021-07-30)Plant anatomists are recurrently looking for safer and faster methods to improve the observations of plants tissues, searching for images with better resolution. Nevertheless, some plant materials are difficult to handle ... -
Both Volatiles and Cuticular Plant Compounds Determine Oviposition of the Willow Sawfly Nematus oligospilus on Leaves of Salix spp. (Salicaceae)
(Springer, 2015-11)Plant volatile organic compounds play a role in selection of host plants by herbivorous insects. Once the insect reaches the plant, contact cues determine host acceptance. Although the willow sawfly Nematus oligospilus ... -
Bottom-up effect of nitrogen fertilization on the density of the corn leafhopper and its impact on both disease incidence and natural parasitism
(Springer, 2022-04-15)The corn leafhopper Dalbulus maidis is a specialist herbivore that attacks maize in the tropical and subtropical regions of the Americas. It is the vector of three relevant plant pathogens that are responsible for severe ... -
Bovine colostral cells : the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)Because bovine maternal and fetal blood supplies are kept separate in utero, calves are immunologically naïve immediately after birth, which puts them at high risk for disease. The acquisition of passive immunity, generally ... -
Bovine colostral cells—the often forgotten component of colostrum
(American Veterinary Medical Association, 2017-05)At birth, neonatal calves have all the essential immune components they need as adult cattle; however, it takes at least 2 to 4 weeks for those components to become fully functional.1,2 The immune system does not become ... -
Bovine coronavirus in Uruguay: genetic diversity, risk factors and transboundary introductions from neighboring countries
(Springer, 2019-11)Bovine coronavirus (BCoV) is a recognized cause of severe neonatal calf diarrhea, with a negative impact on animal welfare, leading to economic losses to the livestock industry. Cattle production is one of the most important ... -
