Efecto de la variación estacional sobre la calidad del agua para consumo animal. Comunicación [PDF]

, 2020
Ponencia y pósterEl agua es un recurso imprescindible y de gran impacto en la producción animal, es por ello que la calidad del agua que beben los animales es tan importante como la cantidad. La calidad de agua para consumo animal queda definida por sus

The Unstable Relationship Between Drought Status and Leaf Water Content Complicates the Remote Sensing of Tree Drought Stress

Global Change Biology, Volume 31, Issue 4, April 2025.
Remote sensing can monitor plant drought stress across ecosystems but is limited by uncertain links between physiological stress and measurements of water content. We examined how water potential and water content, measured in the field, laboratory, and via airborne imaging, vary over time and space in two oak species.

Microclimatic variation regulates seed germination phenology in alpine plant communities

Journal of Ecology, Volume 113, Issue 1, Page 249-262, January 2025.
This study combines novel laboratory experimentation based on detailed field microclimatic data to tackle the understudied topic of germination phenology in alpine habitats. The findings suggest a predictable phenological shift in the germination of alpine plants along microclimatic gradients.

The biophysical dynamics of giant kelp, Macrocystis pyrifera: Seasonal patterns and dispersal mechanisms in the southeast Pacific

Journal of Biogeography, Volume 51, Issue 11, Page 2198-2210, November 2024.
Abstract Aim Dispersal and connectivity play important roles in shaping the population structure of giant kelp, Macrocystis pyrifera, across the western coast of South America. Its high potential dispersal capacity suggests the existence of metapopulations, where discrete habitat patches or groups of patches form subpopulations that interact at some ...

Differential responses of community‐level functional traits to mid‐ and late‐season experimental drought in a temperate grassland

Journal of Ecology, Volume 112, Issue 10, Page 2292-2306, October 2024.
These findings suggest that functional trait composition of grassland communities may shift under climate change‐induced drought, depending on the growing season timings. Trait‐based attempts to predict ecosystem functioning must account for such temporal variation in community trait values.

Uso de recursos alimenticios por un ensamble de loros en la Selva Pedemontana de las Yungas argentinas

Acta Zoológica Lilloana
Los estudios sobre la ecología de forrajeo en loros son limitados, particularmente en la Selva Pedemontana de las Yungas en Argentina. Este estudio examinó durante dos años la dieta y el uso de recursos de seis especies de loros (Amazona tucumana ...

Vertical Distribution of Rocky Intertidal Organisms Shifts With Sea‐Level Variability on the Northeast Pacific Coast

Global Change Biology, Volume 30, Issue 10, October 2024.
This study examined whether the vertical distribution of rocky intertidal taxa has shifted with sea‐level variability occurring at multiple temporal scales and/or long‐term anthropogenic sea‐level rise on the Northeast Pacific Coast. We found that intertidal taxa largely do not exhibit significant vertical distribution shifts coherent with short‐term ...
