Nuevas tecnologías para el monitoreo de pasturas [PDF]

, 2016
Un eficiente anejo del pastoreo no solo implica producir mas pasto sino también requiere de una alta utilización del mismo. El objetivo fue evaluar el uso de drones para la estimación precisa de la disponibilidad forrajera y su variación espacial en un ...

Novel frameshift mutation in PURA gene causes severe encephalopathy of unclear cause. [PDF]

Mol Genet Genomic Med, 2021
Rare diseases present several difficulties for patients, from the delay in the diagnosis to the lack of treatments. Next generation sequencing techniques have improved the search for diagnosis in several such pathologies. Here, we present the case of an undiagnosed six years old boy with severe encephalopathy of unclear cause, whose etiological ...

Silvopastoral systems benefit invertebrate biodiversity on tropical livestock farms in Caquetá, Colombia. [PDF]

Agric For Entomol
Abstract In the Colombian Amazon, there has been long‐term and sustained loss of primary forest threatening biodiversity and climate change mitigation. Silvopastoral practices that integrate trees into livestock production could help address both local economic and wider environmental challenges.

An insight into sainfoin (Onobrychis viciifolia Scop.) breeding: Challenges and achievements

Agronomy Journal, Volume 115, Issue 6, Page 2843-2858, November/December 2023., 2023
Abstract Over the last decade, there has been a renewed interest in sainfoin (Onobrychis viciifolia Scop.), particularly among western Canadian forage and beef‐cattle producers. A major trigger has been the availability of new sainfoin cultivars with improved compatibility with alfalfa (Medicago sativa).

Functional and structural brain network development in children with attention deficit hyperactivity disorder

Human Brain Mapping, Volume 44, Issue 8, Page 3394-3409, June 1, 2023., 2023
This study explores longitudinal development of both functional and structural connectivity across late childhood and in children with ADHD and typically developing controls. We demonstrated that topology of functional and structural connectomes matures differently between ADHD and controls.

Agronomic assessment of two populations of intermediate wheatgrass—Kernza® (Thinopyrum intermedium) in temperate South America

Grassland Research, Volume 1, Issue 4, Page 262-278, December 2022., 2022
Kernza® is a dual‐purpose (grain and forage) perennial crop developed in high latitudes. In a field experiment carried out in a low‐latitude region, high forage yields and high nutritive value were obtained, but grain yields were low, possibly because the vernalization requirements of the species were not completely fulfilled.

The Clean Water Act and biosolids: A 45‐year chronological review of biosolids land application research in Colorado

Journal of Environmental Quality, Volume 51, Issue 5, Page 780-796, September/October 2022., 2022
Abstract The 1972 U.S. Clean Water Act set forth the generation of biosolids. In Colorado, biosolids land application research began in 1976 and continues today. Pastureland research suggested that sewage effluent could effectively be land applied to benefit aboveground plant growth and to polish water prior to reaching receiving waters.

Patterns and controls on island‐wide aboveground biomass accumulation in second‐growth forests of Puerto Rico

Biotropica, Volume 54, Issue 5, Page 1146-1159, September 2022., 2022
Understanding the heterogeneity of biomass accumulation in second‐growth tropical forests following land use abandonment is important for informing ecosystem carbon models and forest restoration efforts. Using airborne lidar data, we quantify patterns and controls on aboveground biomass accumulation in second‐growth forests of Puerto Rico.

Field establishment of little bluestem populations selected for improved laboratory seed germination in simulated dry conditions

Crop Science, Volume 62, Issue 2, Page 958-963, March/April 2022., 2022
Abstract Successful field establishment begins with superior plant genetics, quality seeds, land preparation, sowing depth, weed control, and moisture. Our research examined the field‐establishment plant density of six populations of little bluestem [Schizachyrium scoparium (Michx.) Nash] and three selection generations at three locations over a 3‐yr ...
