Índices Zoométricos en Ovejas Criollas Araucanas [PDF]

International Journal of Morphology, 2010
El ovino criollo Araucano presente en la region de La Araucania, Chile, actualmente se encuentra amenazado por el mestizaje de su material genetico con razas productoras de carne como la Suffolk. Con el objetivo de realizar su caracterizacion racial, se evaluaron 94 hembras provenientes de diferentes rebanos de la region de la Araucania, Chile.

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

Insect 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

Structural 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 ...

REGULACIÓN NEUROENDOCRINA DEL ANESTRO POSPARTO EN LA OVEJA

Tropical and Subtropical Agroecosystems, 2009
  La presente revisión se realizó con el propósito de analizar y discutir los eventos neuroendocrinos implicados en el anestro posparto de la oveja. En los mamíferos, durante la etapa posterior al parto, existe un periodo anovulatorio conocido como

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

The 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

Area, 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

Journal 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

Structural 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.
