    Abstract The identification of the factors controlling the understory species distribution and abundance is essential to understand the ecology and dynamics of natural forests and their management response. We assess the relationships between environmental gradients and shrub functional groups distribution patterns and niche characteristics in a transitional area between the Eurosiberian and Mediterranean biogeographic regions in Northern Spain. Here, 772 plots from the 3rd Spanish National Forest Inventory were used. Shrub functional groups respond to the same complex environmental gradients as trees, i.e., the north-south climatic gradient and a slope gradient. Unimodal response curves of shrub functional groups and families dominate along both gradients, providing evidence of successful functional turnover. Similar to tree species, the niche location of functionally related shrubs is close. Functional groups occupying environments with sharp contrast or transitional environments have the broadest niches, whereas those specialized functional groups occupying localized habitats showed the narrowest niches. The knowledge of shrub species distributions and niche characteristics along complex environmental gradients will improve our ability to discuss potential conservation management goals or threats due to land-use changes and future climate change.

    Abstract 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 perpendicular to the forest-mine boundary and classified according to their shape (concave, convex, straight). Mine sites were colonized from the close forest by woody species, whose colonization intensity depends on the boundary form. The overall colonization intensity decreased with increasing distance to the forest and differed depending on the boundary form. The more intense colonization was found in concave boundaries and the strongest decrease in convex boundaries close to the forest, whereas straight boundaries showed an intermediate colonization pattern. Concave boundaries reached higher woody cover in the basal strata of the mines than convex (up to 2 m) or straight boundaries (up to 1 m) from 11 m to the forest edge, mainly by the presence of dense patches of Cytisus scoparius (L.) Link, with a scattered overstory of Genista florida L. These shrubs might reduce the browsing intensity and act as nurse plants facilitating the establishment of Quercus petraea (Matt.) Liebl. in mine areas at greater distances from the forest edge. The forest-mine boundary form does not affect the forest vertical structure that is homogenous and does not help explain the woody colonization pattern in the mines. We conclude that edge characteristics have a strong potential to be used in the restoration of native forests based on natural processes. The implications of our results for sessile oak ( Quercus petraea (Matt.) Liebl.) forest expansion along edges in fragmented Mediterranean forest landscapes were discussed.

    Abstract 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. Moreover, further studies are necessary to clarify the relative importance of the two facilitation mechanisms in the same community. Background and Objectives: Cytisus multiflorus (L’Her.) Sweet is a predominant shrub species in the Mediterranean grazed open-oak-woodlands found in the central west of the Iberian Peninsula (bioclimatic limit) and is present with Quercus pyrenaica Willd and Quercus ilex subsp. ballota Samp trees. Thus, we assessed the effect of these native shrubs and acorn size, and the effect of excluding large herbivores, on the seedling emergence of two contrasting co-occurring Quercus species under a bioclimatic limit. Materials and Methods: A manipulative field experiment was carried out considering four treatments as a combination of shrubs (shrub/no-shrub) and fence (fenced/open) factors. A total of twenty plots, five replicates for each treatment were available. In each plot, 20 acorns were sown: 10 acorns (5 small and 5 large) for each Quercus species. Acorn emergence was recorded during the first four years following the sowing. Results: Seedling emergence took place mostly in the spring of the first year after sowing. The presence of shrub was the main significant factor and incremented the emergence of both Q. ilex and Q. pyrenaica . The effect of the fence depended on the Quercus species considered, improving only the emergence of Q. pyrenaica . A negative effect with the small acorns was detected but only for Q. pyrenaica . In all treatments, Q. ilex emerged more than Q. pyrenaica . Conclusions: C. multiflorus had a clear facilitative effect on the seedling emergence of Q. ilex and Q. pyrenaica , which was much greater than the physical ...

    Abstract El Chocó biogeográfico (Colombia) es una región biodiversa pero afectada drásticamente por la minería. En este trabajo, se identificaron las especies de plantas vasculares que colonizan áreas afectadas por minería en bosques de la región; en concreto, se recolectaron plantas en diferentes formaciones topográficas de siete minas abandonadas (3-15 años de abandono después del cese de la actividad minera) en tres municipios de la región. Se identificaron 66 especies, 47 géneros y 22 familias. Las familias más representativas fueron Cyperaceae (14,9 % géneros y 25,8 % especies), Melastomataceae (14,9 y 15,2 %) y Rubiaceae (10,6 y 12,1 %), mientras que los géneros con más especies fueron Cyperus (8,5 % especies), Rhynchospora (8,5 %), Scleria (6,4 %) y Spermacoce (6,4 %). La forma de vida predominante fue la herbácea (80,3 % especies) y los hábitats con más especies fueron las llanuras no inundables (36,3 % especies), el ecotono (34,8 %) y las depresiones cenagosas (31,8 %). Las depresiones cenagosas incluyeron más especies exclusivas (42,8 %, n = 42). La revegetación temprana de las minas depende de la historia de vida de las plantas colonizadoras y de factores asociados al sustrato.

    Abstract The role played by rodents in the colonization of acorn-producing plant species has been interpreted in different ways along time. It has gone from a predation relationship, in which rodents destroy seeds by devouring them, to a mutualistic one, in which they leave part of their caches or, more recently consume part of the cotyledons but leave the embryo intact. We studied how three rodent species, Apodemus sylvaticus (wood mouse), Mus spretus (Algerian mouse), and Microtus arvalis (common vole) treat the acorns they consume. The wood mouse and the Algerian mouse have consumed acorns for a long time and participate in this mutualistic relationship by preserving the embryo. The common vole eats acorns for the first time, as it is not a part of its habitual diet. We observed that this rodent species devours the embryo, as opposed to the other two rodent species that usually eat acorns and modifies its behavior over time, suggesting that its way of eating the acorns is not genetically fixed. The common vole has only recently started to enter the distribution areas of Quercus species. Its population density is high during certain periods, reaching plague levels in crops. When its usual food source runs out during these periods, it has to find others which probably include acorns. This rodent species eliminates the embryo during consumption and can, therefore, become a serious problem for acorn-producing species by limiting their colonization process. The three rodent species under study showed the same preference for the Quercus species provided, rejecting acorns of Q. suber and preferring those of Q. ilex subsp. ballota. SIGNIFICANCE STATEMENT: Microtus arvalis (common vole) is considered as an expansive crop pest species in certain parts of Europe, and in comparison with Apodemus sylvaticus (wood mouse) and Mus spretus (Algerian mouse), it does not have co-evolutionary history with Quercus species. Thus, the common vole is suggested to lack a mutualistic relationship with Quercus species where trees benefit from seed-dispersing rodents who then use parts of acorns as a food source. Using laboratory breeding, we showed that two habitual acorn consumers rodent species (wood mouse and Algerian mouse) tend to preserve the acorn embryo, while the expansive common vole that does not include acorns in its diet tend to eat the embryo. We concluded that the feeding behavior of the two habitual acorn consumer benefit the mutualistic relation with Quercus, probably due to the results of natural selection, whereas the expansive species not accustomed to eating acorns would impose a high risk to the natural regeneration of Quercus species.

    Abstract Many studies highlight the role of mixed versus monospecific forests to supply numerous ecosystem services. Most reports of positive mixture effects on carbon storage focus on mixtures that combine tree species with contrasting traits, but little is known on the effect of mixing species that are expected to behave quite similarly as they belong to the same genus. In this study, we assessed the effect of mixed versus monospecific stands of Pinus sylvestris and P. pinaster on carbon storage and exchangeable cations along the soil profile, based on research with six triplets in the northern Iberian Peninsula (Spain). One soil pit of at least 40 cm depth was dug at each plot for organic and mineral horizons characterization. Two trends were found: in the topsoil, higher values of carbon stock and total organic carbon were found in P. sylvestris stands, lower in P. pinaster stands and intermediate in mixed stands; this pattern was related to the C/N ratio of the forest floor. In the intermediate soil layers, it tends to be higher in mixed stands and is related to percentage of fine roots and to the greater thickness of the first mineral horizon. Differences in soil exchangeable cations among stands were related to the total organic carbon content. These results improve our understanding of the mechanisms underlying soil carbon accumulation in mixed stands and emphasize the use of mixtures as a strategy to combat climate change, due to the advantage in the accumulation of carbon in the subsoil layers.

    Abstract Ecological restoration (ER) of terrestrial ecosystems has become widespread in past decades. However, assessing its success is complex mainly due to the diversity of objectives pursued, actions undertaken but also statistical methods for treating data. We demonstrate here that, due to the heterogeneity of collected data, the success of restoration actions can be overestimated in meta-analyses. We advocate analyzing distinctly two types of actions in ER, those aiming at increasing an ecosystem attribute (e.g. species richness of a native plant species, ER+), and those aiming at decreasing it (e.g. invasive species cover, ER-). We also suggest that only one index for assessing the success of a restoration action is not enough. We propose here to complete RR (Remaining Recovery) by a novel index informing on ‘what has been restored by comparison to what should have been recovered’: the ‘Achieved Restoration’ index (AR).

    Abstract La familia Arecaceae es rica en especies, principalmente en el trópico, y constituye una fuente de recursos para la subsistencia de sus pobladores. En el presente trabajo se estudió la riqueza, diversidad, composición y patrones de uso de la familia Arecaceae en tres localidades de la cuenca media del río Atrato en el Chocó, Colombia, con el fin de obtener información que permita su conservación y uso sostenible. Se registraron 29 especies en 18 géneros, siendo Bactris 24.13 y Wettinia 10.34 los géneros más ricos en especies. El Buey mostró más especies y géneros 23 especies, 17 géneros que Beté 15 y 10 respectivamente y Tanguí 14 y 11 respectivamente. La similitud florística entre localidades fue menor al 45. Las especies con mayor peso ecológico y valor de uso fueron: Euterpe oleracea Mart., Oenocarpus bataua Mart., Attalea allennii H.E. Moore, Manicaria saccifera Gaertn., Bactris gassipaes Kunth y Wettinia quinaria O.F.Cook y Doyle R. Bernal. Las categorías de uso con mayor riqueza de especies e importancia cultural fueron: construcción, alimento y uso artesanal; y los órganos más usados fueron tallos y frutos. Los resultados de este trabajo demuestran que el Atrato Medio posee alta riqueza y diversidad de especies de palmas en un contexto regional y nacional. Sin embargo, la relación entre el número de uso y la importancia ecológica de la especie depende de la localidad, lo que indica que la importancia socio-cultural de la especie puede variar entre grupos humanos que comparten una misma cultura o región biogeográfica. Se publicarán estudios a futuro para determinar el papel del tipo de órgano utilizado como materia prima en la demografía y dinámica ecológica de las poblaciones de palma en el Chocó y otras regiones del Neotrópico.
