Glomalin contribution to soil organic carbon under different pasture managements in a saline soil environment
(Taylor & Francis, 2020-10-23)
The glomalin produced by arbuscular mycorrhizal fungi has beneficial effects on soils. We studied the vertical profile of glomalin-related soil protein (GRSP) in pasturelands grown under saline soils and exposed to different ...
Evaluación de dos técnicas de acodamiento para la propagación vegetativa del algarrobo Prosopis chilensis (Mol) Stuntz
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2021-05)
El objetivo general del ensayo fue evaluar el uso de dos métodos de propagación vegetativa en P. chilensis: (A) acodo aéreo y (B) en montículo. En (A) se emplearon árboles de 3,5 años de edad y se ensayaron en dos épocas ...
Agricultural expansion and the ecological marginalization of forest-dependent people
(National Academy of Sciences, 2021-11-02)
Agricultural expansion into subtropical and tropical forests causes major environmental damage, but its wider social impacts often remain hidden. Forest-dependent smallholders are particularly strongly impacted, as they ...
Seasonality, richness and abundance of syrphid flies in greenhouse pepper agroecosystem
(Springer, 2021-06)
Studies were conducted to broaden the current knowledge on seasonality, richness, abundance, and role of syrphids flies in the greenhouse pepper agroecosystem (GPA) in northwestern Argentina. In the GPA, a great richness ...
Comparison of ELISA using recombinant LipL32 and sonicated antigen of leptospira for detecting bovine leptospirosis
(Elsevier, 2022-01)
Leptospirosis is one of the most widely distributed zoonosis in the world. Bovine leptospirosis is a serious problem in bovine production, causing reproductive losses. The aim of this work was to compare recombinant LipL32 ...
Variaciones estacionales de parámetros reproductivos, calidad seminal y niveles de testosterona en carneros Highlander
(Facultad de Medicina Veterinaria, Universidad Nacional Mayor de San Marcos, 2021-10-27)
El objetivo del trabajo fue determinar el efecto de la estación del año (fotoperiodo) sobre la circunferencia escrotal (CE), peso testicular (PT), volumen testicular (VT), capacidad de servicio (CS), concentración plasmática ...
Penetration by Botryosphaeriaceae species in avocado, guava and persimmon fruit during postharvest
(Wiley, 2021-11-05)
Botryosphaeriaceae species have a wide host range and a worldwide distribution. These fungal species can colonize several plant organs, such as the trunk, leaves and fruit. Some Botryosphaeriaceae species cause important ...
Role of proteases in the response of plants to drought
(Elsevier, 2021-09-30)
Plants are sessile organisms that, to survive they develop response mechanisms under water deficit conditions. Plant proteases play an essential role in a diversity of biological processes, among them tolerance to drought ...
Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
(Elsevier, 2021-12)
It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ...
MVAΔ008 viral vector encoding the model protein OVA induces improved immune response against the heterologous antigen and equal levels of protection in a mice tumor model than the conventional MVA
(Elsevier, 2021-11)
Modified vaccinia Ankara virus (MVA) is extensively used as a vaccine vector. We have previously observed that MVAΔ008, an MVA lacking the gene that codes for interleukin-18 binding protein, significantly increases CD8+ ...
