Ring density record of phenotypic plasticity and adaptation to drought in Douglas-fir
(Elsevier, 2009-08)
Microdensity profiles of Douglas-fir’s clones and weather data were used to study phenotypic plasticity (dendroplasticity). Within-ring microdensity was interpreted as the variation of tree response to drought constraints ...
Estudio de la cinética de eliminación de marbofloxacina y desarrollo de un modelo predictivo de residuos en aves de engorde en condiciones de temperaturas extremas de explotación estival e invernal
(2018-03-22)
In poultry farming, ambient temperature should be maintained in a range between 18 to 24 ° C, to avoid physiological changes, which modify the kinetic behavior of antimicrobial drugs used, and interfering with withdrawal ...
Impacto de factores de manejo sobre la concepción en vaquillonas lecheras
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2020)
El incremento del número de vaquillonas preñadas por unidad de tiempo mejora la eficiencia reproductiva en rodeos lecheros. El objetivo de este trabajo fue analizar el efecto de factores de manejo sobre la concepción. Se ...

An experimental approach to the brood reduction hypothesis in Magellanic penguins
(Wiley Blackwell Publishing, Inc, 2017-08-07)
In many bird species, eggs in a brood hatch within days of each other, leading to a size asymmetry detrimental to younger siblings. Hatching asynchrony is often thought of as an adaptive strategy, and the most widely studied ...
Variation in parental care in the spectacled tyrant Hymenops perspicillatus is associated with increased nest predation in grassland fragmentsUnterschiede in der Brutpflege beim Brillentyrann steht in Verbindung mit einer erhöhten Nest-Prädationsrate in fragmentiertem Grasland
(Wiley Blackwell Publishing, Inc, 2016-04)
Predation risk on birds is often an important source of natural selection that shapes parental care and may promote behavioral changes. Parents can often estimate certain risks and adjust their behavior to reduce the ...
Growth Curves of Wild and Reintroduced Broad-Snouted Caimans (Caiman latirostris) and Their Management Implications
(Sociedade Brasileira de Herpetologia, 2020-08)
We describe body growth functions of broad-snouted caimans (Caiman latirostris) for wild and reintroduced individuals. Snout-vent length (SVL, cm) and age of young individuals and adult females were recorded for two different ...
Short-term effect of UVR on vertical distribution of Cyrtograpsus altimanus and Alexandrium tamarense from Atlantic Patagonia
(Pontificia Universidad Católica de Valparaíso, 2017)
Modelled yield and water use efficiency of maize in response to crop management and Southern Oscillation Index in a soil-climate transect in Argentina
(Elsevier Science, 2012-10)
Maize responses to individual management factors have been widely investigated but studies of higher-order interactions involving multiple factors are rare. This paper investigates the responses of grain yield and water ...
