Efecto de la pérdida de grasa dorsal y peso corporal sobre el rendimiento reproductivo de cerdas primíparas lactantes alimentadas con tres diferentes tipos de dietas

open access: yesRevista Científica, 2010
Se evaluaron 90 cerdas híbridas primíparas de traspatio, que se clasificaron de acuerdo al tipo de dieta en 3 grupos: G1, escamocha (residuos alimenticios de consumo humano); G2, escamocha y concentrado y/o granos, y G3, alimento balanceado.

Gender Differences in the Impact of Domestic and International Remittances on Household Food Security. Evidence From Rural Zimbabwe

open access: yesPoverty &Public Policy, Volume 18, Issue 4, December 2026.
ABSTRACT Despite efforts, food security remains an elusive goal in rural Africa. Without robust safety nets, households employ alternative coping strategies, including internal and international migration to leverage remittances. Using data from a 2024 nationally representative cross‐sectional survey of 17,942 rural households conducted by the Zimbabwe

Tramo corto de la curva de rendimientos, cambio de régimen inflacionario y expectativas de inflación en Colombia

open access: yesEl Trimestre Económico, 2008
La consideración de la prima de riesgo de inflación en la ecuación de Fisher y la rápida caída en la inflación en Colombia entre los años 1999 y 2000 nos permiten examinar la hipótesis de linealidad para los diferenciales esperados de inflación entre 6 y

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

open access: yesFunctional Ecology, Volume 40, Issue 11, Page 3398-3421, November 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Theia: An end‐to‐end edge‐AI mobile framework for high‐throughput field phenotyping and on‐device geometric morphometrics

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 11, Page 3157-3169, November 2026.
Abstract Geometric morphometrics (GM) is widely used to study phenotypic variation in ecological and evolutionary research, but the throughput of manual landmark digitization limits how large morphometric datasets can practically become, especially in field studies that would benefit from rapid on‐site feedback.

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize

open access: yesNew Phytologist, Volume 252, Issue 3, Page 1296-1313, November 2026.
The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

Precipitation shapes colour polymorphism in a widespread spider

open access: yesFunctional Ecology, Volume 40, Issue 10, Page 3176-3189, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Colour polymorphism, the presence of multiple colour variants within a population, is a common example of intraspecific phenotypic variation and has served as a model for studying drivers of diversity.

Flexibilidad de precios y estabilidad de la producción: punto de vista de un antiguo keynesiano

open access: yesLecturas de Economía, 1996
n este trabajo James Tobin discute la validez de las principales tesis que diferencian la macroeconomía keynesiana de la macroeconomía neoclásica. Su discusión la dirige a la nueva teoría macroeconómica –que busca dar una fundamentación microeconómica al
