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 […]

A new methane sink discovered

Subterranean atmospheres may act as daily methane sinks is the title of a paper authored by several researchers from the Spanish National Museum for Natural Sciences, the University of alicante and IRNAS, and published in volume 6 of the journal Nature Communications on 27 April, 2015. Until today, it was known that methane, one of […]

The Spanish Ministry for Education, Culture and Sport publishes the report of the contract for the integral study of the state of conservation of Altamira Cave and its Paleolithic art

The report, published as the number 24 of the prestigious book series “Monographs of the National Museum and Research Centre of Altamira”, has been finally published and could be assessed directly by the international scientific community. This book constitutes the crowning of the studies conducted in the cave by a research team which began working […]
