The different plant organs (leaf, stem and root) work on a coordinate way

Plants, like so many organisms, have several specialized organs for different functions. Thus, the main role of leaves is light capture, while roots are related with soil water and nutrient uptake, and stems supply these water and nutrients to the leaves. According with their functional diversification, differences among organ characteristics could be expected. […]

Facilitating the afforestation of Mediterranean polluted soils by nurse shrubs

Experimental sowing of Quercus ilex acorns under shrubs in the Guadiamar Green Corridor (María T. Domínguez in the photo).

The revegetation of polluted sites and abandoned agricultural soils is critical to reduce soil losses and to control the spread of soil pollution in the Mediterranean region, which is currently exposed to the […]

A member of IRNAS, invited speaker at the International Workshop Assessing Digital Solutions in Cave and Rock Art Research

Dr. Miguel A. Rogerio-Candelera, from IRNAS’ research group “Environmental Microbiology and Cultural Heritage”, has been invited by the organisation of the International Workshop Assessing Digital Solutions in Cave and Rock Art Research, to teach the conference Digital image analysis-based strategies for painted rock art recording. The Workshop, organised by the researchers from the University of […]

Variation in leaf traits of semiarid woody plants

Peter Grubb, Malole Díaz-Villa, Lawren Sack and Teodoro Marañón (from left to right) at Cabo de Gata, April 7th 2000.

Plants living in semiarid environments have singular adaptations to cope with the shortage of water, including morphological and physiological mechanisms to grow avoiding water loss, or by storing water in leaves and […]

The water availability determines the functional properties of woody communities

Understanding which factors govern the processes in plant communities constitutes one of the main challenges in ecology. The functional approach is a broadly-known key tool to better understand these issues; is based on the functional trait variation along environmental gradients. Thus, the functional approach allows as to discern the filtering mechanisms and the […]

Mycorrhizas in oak seedlings are affected by cork oak forest decline

In forests affected by problems of tree dieback, tree health status could be an additional factor shaping mycorrhizal abundance in soils, which in turn could affect the probability of seedling establishment in a feed-back process.

A research team in the IRNAS has studied how cork oak (Quercus suber) decline can impact […]

Why is seed production so variable in Mediterranean oak species?

Understanding the proximate factors that govern the widespread mast-seeding process (i.e., the large interannual variability in seed production) is a question of considerable ecological and evolutionary interest that remains poorly understood. The identity and effect of these factors may vary among coexisting species that differ in leaf habit, potentially resulting in temporally asynchronous patterns of […]
