PRODUCCIÓN ORGÁNICA DE LECHE DE OVEJA [PDF]

open access: yesTropical and Subtropical Agroecosystems, 2014
<p>Organic production systems are based on natural processes, leveraging local resources and decreasing in soil degradation. Effectiveness of milk production of organic systems vs. conventional production systems is a subject open to debate.

Differences in within-plant oviposition preferences and immature survival between Orius predators and the importance of spatial availability of prey. [PDF]

open access: yesInsect Sci
Orius predators oviposit endophytically, and plant characteristics play an important role in their oviposition choices. In this study, we show that oviposition preferences differ between species, and that these differences may correlate with juvenile performance.

3D‐printed concrete footbridges: An approach to assess the sustainability performance

open access: yesStructural Concrete, Volume 24, Issue 6, Page 7705-7725, December 2023., 2023
Abstract Digital fabrication with concrete (DFC) is fast becoming an attractive alternative for components (i.e., façades, urban furniture) and structural typologies (i.e., short‐span footbridges, columns, floor systems) for which complex geometries derived from particular aesthetical criteria and/or construction time constrictions are governing ...

Surface textures of detrital pyroxenes in coastal dune sands (western Gulf of Mexico, Mexico): Implications for their preservation and geoenvironmental processes

open access: yesThe Depositional Record, Volume 9, Issue 4, Page 789-809, November 2023., 2023
Breakage along cleavage surfaces and little abrasion in clinopyroxene grains occurs after fluvial, marine and aeolian transport. Compactness measurements are an alternative shape descriptor to determine the morphology of minerals. Abstract This work investigates how the surface textures and morphology of pyroxene grains evolve during their source‐to ...

Feeling/thinking the archive: Participatory mapping Marronage

open access: yesArea, Volume 55, Issue 3, Page 416-425, September 2023., 2023
Short Abstract This article develops a decolonial participatory method to map the geographies of descendants of fugitives from slavery, or Maroons, to disrupt white‐Mestizo constructions of Latin American territories. With the researcher‚ Äôs assistance, members of San Basilio de Palenque, Colombia, used their knowledge and emotions as a lens through ...

Adaptive phenotypic and genomic divergence in the common chaffinch (Fringilla coelebs) following niche expansion within a small oceanic island

open access: yesJournal of Evolutionary Biology, Volume 36, Issue 9, Page 1226-1241, September 2023., 2023
We study the process of local adaptation in the common chaffinch to two contrasting habitats on the island of La Palma, the humid laurel forest and the dry pine forest. We document habitat‐related phenotypic divergence, and using genome–environment association analysis on a small fraction of the genome, we detect adaptive genomic divergence at a small ...

Application of high‐performance fibre reinforced concrete to precast girders for road bridges: Conceptual considerations and numerical analyses

open access: yesStructural Concrete, Volume 24, Issue 4, Page 4645-4659, August 2023., 2023
Abstract High‐performance fiber‐reinforced concrete (HPFRC) can be considered a promising material for the construction of precast concrete girders for road bridges. This paper presents conceptual considerations and numerical analysis to support this statement. The HPFRC is a compromised alternative between FRC and UHPFRC mixes.

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the prospection of biological hazards of interest in food safety in Spain (2)

open access: yesFood Risk Assess Europe, Volume 1, Issue 1, March 2023., 2023
Abstract This report addresses the prospection of biological hazards for some types of food that may pose a risk to the population and that are not currently included in the official control programs in Spain. It completes and updates the 2018 report by the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN, 2018). A number

The Case of Piruani: Contested Justice, Legal Pluralism, and Indigeneity in Highland Bolivia

open access: yesPoLAR: Political and Legal Anthropology Review, Volume 44, Issue 1, Page 60-74, May 2021., 2021
Abstract The 2009 Bolivian constitution included provisions that establish a radical form of de jure legal pluralism by creating a parallel legal system that gives full recognition to the nonstate legal orders and forms of conflict resolution of Indigenous communities.

The world's southernmost tree and the climate and windscapes of the southernmost forests

open access: yesEcography, Volume 44, Issue 1, Page 14-24, January 2021., 2021
The world's southernmost tree has been documented along with the condition and growth pattern of the world's southernmost forest on Isla Hornos, Chile. The distribution of trees at broad scales is strongly influenced by the abiotic environment and determining the position and condition of tree limits around the world is an important way to monitor ...
