The power of ionic movements in plants

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2232-2240, March 2026.
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...

Espacio público y comercio en la ciudad contemporánea

open access: yes, 2015
La relacion entre actividad comercial y espacio publico es tan antigua como el propio concepto de ciudad. La cultura posmoderna ha implantado cambios en la percepcion comercial del espacio publico que llegan a afectar su consideracion estetica y a ...

Climate adaptation and functional constraints drive pollen evolution in Apiales

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.

Roots of resilience: Assessing child and adolescent nature connectivity in the Mediterranean Region of Murcia (Spain)

open access: yesPeople and Nature, Volume 8, Issue 2, Page 378-391, February 2026.
Abstract Children today spend less time outdoors than previous generations, with potential consequences for health, learning and pro‐environmental attitudes. We assessed children's connection with and exposure to nature in a Mediterranean setting using the Nature Connection and Experience Index (NCEI), a composite measure that integrates an affective ...

Walkability index for the city of Bogotá

open access: yesRevista de Arquitectura (Bogotá), 2019
Resumen La movilidad peatonal es un aspecto recurrente en los discursos de la ciudad actual. Se espera que en las ciudades se generen espacios urbanos que fomenten la caminabilidad y, de esta manera, se promueva la reducción de la movilidad vehicular y ...

El espacio construido [PDF]

open access: yes, 2004
Hace referencia a. la ciudad, sin dudas, la obra más grande realizada por el hombre. La ciudad es espacio construido, tanto hacia afuera como hacia adentro, expresando las dos dimensiones de la vida urbana.
