Range‐wide intraspecific variation reflects past adaptation to climate in a gypsophile Mediterranean shrub

Journal of Ecology, Volume 112, Issue 7, Page 1533-1549, July 2024.
Despite strong specialization to gypsum soils, past divergent selection related to climatic gradients has driven adaptive population differentiation in Lepidium subulatum. All populations showed high but similar plasticity to drought, indicating that selection did not act against plasticity in harsh environmental conditions.

Distribution of grasses along an altitudinal gradient in a Venezuelan paramo Distribución de gramíneas a lo largo de un gradiente altitudinal en un páramo de Venezuela

Revista Chilena de Historia Natural, 2004
In Venezuelan paramos grasses, after Asteraceae, are the second family in numerical importance. We studied their distribution in an altitudinal gradient located in Venezuela, Sierra de La Culata, between 2,500 and 4,200 m of altitude.

Distribución espacial del polen en un gradiente altitudinal en Michoacán, México

Revista Mexicana de Biodiversidad, 2013
La región del Balsas considerada zona prioritaria para su conservación, debido a su alta diversificación y por la cantidad de endemismos, fue nuestra zona de estudio en la cual se examinó la relación entre la vegetación con la composición de la lluvia de

Erosionabilidad del suelo a lo largo del gradiente climático Coll de Rates - Benidorm, Alicante [PDF]

, 1996
[Resumen] Se estudia la influencia del clima sobre la erosionabilidad de los suelos mediante la cuantificación de la estabilidad de los agregados por medio del test de Emerson, por impactos de gotas (CNO y TOI) y por ultrasonidos (UD) a lo largo del ...

Pushing the limits of C3 intrinsic water use efficiency in Mediterranean semiarid steppes: Responses of a drought‐avoider perennial grass to climate aridification

Functional Ecology, Volume 38, Issue 4, Page 955-966, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intrinsic water use efficiency (WUEi) reflects the trade‐off between photosynthetic carbon gain and water loss through stomatal conductance and is key for understanding dryland plant responses to climate change.

Asymmetrical local adaptation of maize landraces along an altitudinal gradient

Evolutionary Applications, 2008
AbstractCrop landraces are managed populations that evolve in response to gene flow and selection. Cross‐pollination among fields, seed sharing by farmers, and selection by management and environmental conditions play roles in shaping crop characteristics. We used common gardens to explore the local adaptation of maize (Zea mays ssp.

Estructura de la comunidad de pequeños mamíferos en un gradiente altitudinal, Reserva Río Blanco, Manizales, Caldas, Colombia

Acta Biológica Colombiana, 2004
Se estudió la estructura de la comunidad de pequeños mamíferos no voladores en tres estaciones (2.500, 3.000 y 3.500 msnm) en el gradiente altitudinal de la Reserva Río Blanco (Caldas), en la vertiente occidental de la Cordillera Central colombiana.

Changes in species richness with climate change in subalpine communities are dependent on regional environmental conditions and local functional composition

Journal of Vegetation Science, Volume 35, Issue 2, March/April 2024.
We compared the effects of climate change on species richness of subalpine plant communities from the Massif Central and intermediate Alps (France). In the former species richness increased by ca. 10% due to increasing irradiance in a very wet climate, while it decreased in the latter by ca.
