Aims
Unravelling the most prevalent causal direction between diversity and function in naturally recovered plant assemblages can greatly improve our understanding on the functional significance of diversity and its applications under the ongoing environmental changes. In this study, we apply a structural equation model framework to unravel the most...
Aims
We studied the regeneration dynamics of woodlands and abandoned old fields in a landscape dominated by Quercus suber in its lower limits of rainfall and temperature. Two hypotheses were established: (1) regeneration of Quercus species is strongly favored by the presence of tree cover; and (2) growth of Q. suber is driven by the climatic variab...
We evaluated the ecological significance of the boundary form between two patches with contrasting vegetation (mine grassland and adjacent forest) on woody colonization and forest expansion in open-cast coal mines in Northern Spain. Woody colonization and browsing traces were measured on three mine sites, along 24 transects that were laid out perpe...
Research Highlights: The regeneration of Quercus species is usually very difficult in many
oak woodlands transformed by livestock farming. Some studies have reported that shrubs can facilitate regeneration. However, the strength of interaction may vary depending on, among other factors, the shrub species and the stress tolerance of the oak species....
AimsWe studied the regeneration dynamics of woodlands and abandoned old fields in a landscape dominated by Quercus suber in its lower limits for rainfall and temperature. Two hypotheses were established: (1) recruitment of Q. suber is restricted more by abiotic variations than other species adapted to more extreme Mediterranean conditions; and (2)...
The establishment of oak trees is often a slow and difficult process. Hence, it is necessary to determine the characteristics that can lead to improving their regeneration. In this genus, seed size is highly variable both at the interspecific and intraspecific levels, and the effects of intrapopulation variability are not well understood, being eve...
Under semi-arid Mediterranean conditions in Spain, soil stabilization on mining wastes is often achieved by using the hydroseeding of commercial mixtures of non-native seeds. However, the behaviour of these species in providing rapid vegetation cover of exposed substrate in a regime of scarce and markedly seasonal rainfall, and their performance wh...
pesar de los avances en los últimos años en las técnicas de restauración de ecosistemas forestales
afectados por perturbaciones antrópicas, los resultados obtenidos no son siempre satisfactorios.
Principalmente por problemas en la correcta selección de los lugares en los que realizar las siembras
o plantaciones, problemas con las técnicas de planta...
Can shrubs (Cytisus multiflorus) and large herbivore exclusion (fence) facilitate seedling survival and growth of marcescent and sclerophyllous oaks (Quercus pyrenaica vs Q. ilex subsp. ballota) under a bioclimatic limit in Mediterranean grazed areas? Open oak woodlands in central-western Spain (41º13’ N, 6º24’ W). A two-year field experiment was c...
Traditionally, the shrub was considered as a harmful element for the restoration of plant species, but recent studies showed the facilitating role of shrub in Mediterranean forest restoration. Nevertheless, the effects generated can vary depending on the environment and shrub species involved. In this study, we evaluated if shrubs (Cytisus multiflo...
The characterization of suitable microsites for tree seedling establishment and growth is one of the most important tasks to achieve the restoration of native forest using natural processes in disturbed sites. For that, we assessed the natural Quercus petraea forest expansion in a 20-year-old reclaimed open-cast mine under sub-Mediterranean climate...
La restauración de bosques autóctonos en zonas degradadas mediante procesos naturales tiene como principal
objetivo la caracterización de micrositios adecuados para el establecimiento y desarrollo de las plántulas
de árboles. En este trabajo se ha evaluado la expansión natural del bosque de Quercus petraea en un
hueco minero restaurado hace 20 años...
In this study, we combined the analysis of a coenocline with Huisman–Olff–Fresco (HOF) modelling of species behaviour to describe colonization patterns of woody species on reclaimed coal wastes in northern Spain. We hypothesize that fine-scale variation in abiotic factors along the forest-grassland gradient that appears after mining restoration aff...

In arid and semi-arid ecosystems, the presence of woody neighbours affects the existence of several herbaceous species by modifying critical aspects of the environment (e.g., soil humidity, nutrient content or light availability) beneath their canopies. Herbaceous species growing in the understory of Pinus pinaster may be distinct from those in ope...
Plant trait information is essential for understanding plant evolution, vegetation dynamics, and vegetation responses to disturbance and management. Furthermore, in Mediterranean ecosystems, changes in fire regime may be more relevant than direct changes in climatic conditions, making the knowledge of fire-related traits especially important. Thus...
Cytisus multiflorus is a leguminous matorral shrub native to the NW Iberian Peninsula, where it is one of the most important species in the extension of matorral at the expense of set-aside agricultural land. Dehesas have traditionally been used for extensive livestock raising and matorral was periodically burnt, cut or pulled out. The two latter p...
Demographic changes in Cytisus balansae populations were studied during the first 10 yr after a fire, by comparing populations of different ages in which different cohorts were considered. In the study area this species constitutes a monospecific formation which undergoes periodic burning. We distinguished both new genets (seedlings or plants origi...
Communities of plants determine nonrandom spatial patterns defined by the intervention of abiotic and biotic factors acting at different
spatial scales. We consider the influence of shrubs as one of the most important factors (biotic) affecting these spatial patterns at microscale. The macroclimate could be considered one of the most important fact...
Se analizan las implicaciones ecológicas de la forma del borde entre dos manchas de vegetación
con fuerte contraste: vegetación herbácea resultado de la restauración, 15 años atrás, de un antiguo
hueco minero de carbón (Guardo, Palencia), y la masa forestal adyacente de roble albar. Para ello se
mide la intensidad de colonización de leñosas y las e...
The performance of introduced species when interacting with colonising herbs and shrubs from the surrounding areas has become an important issue in plant ecology and restoration management. In this paper, we examined the influence of hydroseeding a commercial seed mixture on the revegetation of uranium mine wastes under a semi-arid Mediterranean cl...

para el desarrollo del estudio fue la Sierra d...
Eight dump slope sites differing two by two in revegetation treatment (hydroseeding or not) and aspect (north/south) were monitored annually during three years. The HJ-Biplot multivariate technique [1] was used to investigate the way and order in which treatment and aspect contributed to determining changes in the community composition, and to iden...
In Sanabria Natural Park (Castilla y Leo´n Region, Spain),
fires are a frequent occurrence mostly caused by humans. The
aim of this study was to determine the effect of fire recurrence
on the structural characteristics, in particular biodiversity, of
different communities in this area. Fourteen sites, ten heathlands
dominated by Erica australis and...
Comparative plant successional studies on derelict sites are providing significant insights into vegetation dynamics to ensure the success of future revegetation projects in these areas and, in the short-term, by using a space-for-time substitution. In this paper we describe, in relation to site exposure, vegetation development on waste rock materi...
Shrubs are an important source of food for domestic livestock and wildlife in semiarid areas. This is particularly true during dry periods when forage from natural pastures is scarce and its quality is low. Cytisus multiflorus is a leguminous shrub which is endemic to the Northwestern Iberian peninsula. This species occurs in poor soils and in degr...
Postfire regeneration in Cytisus oromediterraneus, a Mediterranean-basin mountain matorral species, shows a wide range of possibilities and variations in sexual and asexual regeneration. Its interpretation requires basic information on the below-ground structure of parent plants as well as on the origin and development of seedlings and various rame...
In the absence ofvegetative cover mining spoils can be
subject to leaching, and to erosion by wind and water; as well
as being unsightly. Rivers and streams can became clogged or
polluted and adjacent areas can be con taminated. Although
such wastes can be stabilized by physical means, the
alternative is to cover the waste with vegetation. Revegeta...
