Key message Subarctic plants in summer (subjected to continuous light) showed photosynthetic pigment contents mainly driven by PPFD (unrelated to day/night cycles) and a xanthophyll cycle responsiveness to PPFD exacerbated during night-times. Abstract Composition and content of photosynthetic pigments is finely tuned by plants according to a subtle equilibrium between the absorbed and used energy...
Key message Intra-annual increment patterns and wood production are coupled with rainfall seasonality in five tree species of a Tumbesian tropical dry forest. However, climatic responses show variation among species. Abstract In many tropical dry forests, information on radial-growth rates and phenology of wood formation is still lacking. However, such information is needed to better manage these...
Key messageSex and site conditions modulate intra- and inter-annual secondary growth and its climatic sensitivity in a dioecious Mediterranean conifer. Abstract Divergent evolutionary pressures associated with differential reproductive costs in dioecious trees may lead to sex-related variation in non-reproductive functions. Sex-related differences may be site-dependent, with different outcomes...
Mangrove forests are ecosystems made up of several woody plants living in saline coastal sedimentary habitats. In order to deal with the high salinity of the substrate, mangrove trees possess a number of different mechanisms to exclude, sequestrate or excrete the excess of salt. The black mangrove (Avicennia germinans L.), one of the dominant species in Central America, is characterized by high levels...
