    Are pine-oak mixed stands in Mediterranean mountains more resilient to drought than their monospecific counterparts?
    (Elsevier, 2021-01-25) Muñoz-Gálvez, Francisco J.; Herrero, Asier; Pérez-Corona, Esther; Andivia Muñoz, Enrique
    Climate change projections point to an increase in the intensity and frequency of extreme drought events with important negative impacts on forest functioning. Predicting these impacts constitutes a crucial challenge for forest managers and for the maintenance of ecosystem services supply. Promoting mixed stands seems a promising strategy for adapting forest ecosystems to ongoing climate change. However, some uncertainty exists regarding whether admixture can improve growth resilience to extreme drought events. Here, we aim to assess tree growth response to drought in mixed and monospecific stands of Pinus sylvestris L. and Quercus pyrenaica Willd. in central Spain. We built tree-ring chronologies and evaluated tree growth sensitivity to water availability and growth resilience components to extreme droughts using linear mixed models. We found contrasting speciesand climate-specific responses to admixture. Q. pyrenaica growth was significantly higher in mixed than in monospecific stands, especially in years without water limitations, while P. sylvestris showed higher growth in mixed stands under dry conditions. However, our results showed a species-specific trade-off between resistance and recovery. While P. sylvestris showed higher resistance but lower recovery to drought events in mixed than monospecific stands, Q. pyrenaica showed higher recovery but lower resistance. This trade-off might explain the absence of admixture effects on species resilience. Our results highlight the importance of considering speciesspecific responses to water availability and associated trade-offs when evaluating admixture effects on drought vulnerability. Overall, we show a positive effect of admixture on the long-term growth stability in response to average climate conditions, but no effects in short-term resilience capacity to increasingly common extreme dry conditions. Consequently, admixture can promote forest productivity stability but should be carefully considered as a management solution for promoting the resilience of Mediterranean mountain forests to increasing aridity.

    Positive associations among rare species and their persistence in ecological assemblages
    (Nature Research, 2019-12-16) Calatayud, Joaquín; Andivia Muñoz, Enrique; Escudero, Adrián; Melián, Carlos J.; Bernardo-Madrid, Rubén; Stoffel, Markus; Aponte, Cristina; Medina, Nagore G.; Molina-Venegas, Rafael; Arnan, Xavier; Rosvall, Martin; Neuman, Magnus; Ari Noriega, Jorge; Alves-Martins, Fernanda; Draper, Isabel; Luzuriaga, Arantzazu; Ballesteros Cánovas, Juan Antonio; Morales-Molino, César; Ferrandis, Pablo; Herrero, Asier; Pataro, Luciano; Juen, Leandro; Cea, Alex; Madrigal-González, Jaime
    According to the competitive exclusion principle, species with low competitive abilities should be excluded by more efficient competitors; yet, they generally remain as rare species. Here, we describe the positive and negative spatial association networks of 326 disparate assemblages, showing a general organization pattern that simultaneously supports the primacy of competition and the persistence of rare species. Abundant species monopolize negative associations in about 90% of the assemblages. On the other hand, rare species are mostly involved in positive associations, forming small network modules. Simulations suggest that positive interactions among rare species and microhabitat preferences are the most probable mechanisms underpinning this pattern and rare species persistence. The consistent results across taxa and geography suggest a general explanation for the maintenance of biodiversity in competitive environments.

    Long term forest management drives drought resilience in Mediterranean black pine forest
    (Springer, 2021-05-10) Lucas Borja, M. E.; Andivia Muñoz, Enrique; Candel Pérez, D.; Linares, J. C.; Camarero, J. J.
    Spanish black pine showed greater resilience and resistance, but generally lower recovery to drought events in managed than in unmanaged forest stands under Mediterranean humid climate. Abstract Drought negative efects on forest ecosystems are projected to increase under global warming all over the world. In this context, forest management can be an efective option for reducing drought impacts and increasing tree growth stability to extreme drought events. Here, we aim to evaluate black pine (Pinus nigra subsp. salzmannii) growth response to climatic variability and drought events in managed and unmanaged stands under similar Mediterranean climatic conditions. Drought events were identifed using long-term climatic data, and basal area increments were calculated for 100–120-year old trees cored in managed and unmanaged plots. Results showed that tree size, temperature, and the interaction between management treatment and water availability signifcantly infuenced tree growth. Basal area increment was reduced in response to the 1983, 1991, 1994‒1995, 1999–2000 and 2005 drought events. Trees in managed plots showed lower growth reductions in response to drought than those located in unmanaged plots, probably experiencing higher competition for soil water, whereas the reverse happened under wet climate conditions. Black pines showed greater resilience and resistance, but generally lower recovery to drought events in managed than in unmanaged stands. Our results suggest that forest management enhances drought tolerance in black pine stands, which may help to ameliorate the negative impacts of global warming across Mediterranean forest ecosystems.

    Bird services applicable to mine restoration: a case study of Sand Martin (Riparia riparia) burrow construction
    (Springer, 2019-09-17) Rohrer, Zoë; Rebollo, Salvador; Andivia Muñoz, Enrique; Rodríguez, Carlos; Franco, Juan
    Vertical banks in mining sites can provide safe nesting sites for burrowing bird species. These burrows can then, in turn, provide nest sites for species unable to create burrows themselves, especially in areas where the abundance of safe nesting holes is a limiting factor. Thus, primary burrowing species can provide ecosystem services for secondary cavity-nesting species. Our objective was to study the availability of burrows of biotic origin in mining sites, and their role in improving colonization and local biodiversity of cliff-nesting birds (birds that rely primarily on rocky or sandy walls to breed). We selected the Sand Martin because it is a colonial ecological engineer species that nests frequently in mining sites. First, we estimated Sand Martin burrow abundance and occupation rates and identified secondary cavity-nesting birds in 8849 burrows from 30 colonies in ten mining sites in central Spain. Second, we studied the dynamics of the Sand Martin burrows, by estimating annual construction and disappearance rates. Finally, we studied factors that could favour secondary cavity-nesting bird occupation. We found that Sand Martins burrowed more than was previously estimated in mining sites, and that their burrows were used by five species of secondary cavity-nesting birds. The number of available burrows each year varied due to relatively high annual construction and disappearance rates. Numbers of Sand Martin pairs and burrows in the colonies were the main factors favouring secondary cavity occupation. Our results support promoting Sand Martins in mine restoration projects, not only to benefit this endangered bird, but also because their ecosystem services can benefit other cliff-nesting species of birds, thus increasing local biodiversity.

    Restoring oak forests through direct seeding or planting: Protocol for a continental-scale experiment
    (Public Library Science, 2021-11-04) Leverkus, Alexandro B.; Levy, Laura; Andivia Muñoz, Enrique; Annighöfer, Peter; De Cuyper, Bart; Ivetic, Vladan; Lazdina, Dagnija; Löf, Magnus; Villar Salvador, Pedro
    The choice of revegetating via direct seeding or planting nursery-grown seedlings influences the potential stresses suffered by seedlings such as herbivory and drought. The outcome of the balance between both revegetation methods may ultimately depend on how species identity and traits such as seed and seedling size interact with environmental conditions. To test this, we will conduct a continental-scale experiment consisting of one mini-experiment replicated by multiple participants across Europe. Each participant will establish a site with seeded and planted individuals of one or more native, locally growing oak (Quercus) species; the selection of this genus aims to favour continental-scale participation and to allow testing the response of a widely distributed genus of broad ecological and economic relevance. At each site, participants will follow the present protocol for seed collection, seeding in the field, nursery cultivation, outplanting, protection against herbivores, site maintenance, and measurement of seedling performance and environmental variables. Each measurement on each species at each site will produce one effect size; the data will be analysed through mixed-effects meta-analysis. With this approach we will assess the main effect of revegetation method, species, plant functional traits, and the potential effect of site-specific effect moderators. Overall, we will provide a continental-scale estimate on the seeding vs. planting dilemma and analyse to what extent the differences in environmental conditions across sites, seed size, functional traits, and the phylogenetic relatedness of species can account for the differences in the effect of revegetation method on seedling performance across study sites and species.

    Assessing Tree Drought Resistance and Climate-Growth Relationships under Different Tree Age Classes in a Pinus nigra Arn. ssp. salzmannii Forest
    (MDPI, 2021-08-27) Esteban Lucas-Borja, Manuel; Bose, Arun K.; Andivia Muñoz, Enrique; Candel Pérez, David; Plaza Álvarez, Pedro A.; Linares, Juan Carlos
    The magnitude of drought impact in forest ecosystems depends on which group of trees are more severely affected; greater mortality of smaller trees can modulate the trajectories of succession, while the mortality of larger trees can disproportionately offset the ecosystem’s carbon balance. Several studies have documented a greater vulnerability of large trees to extreme droughts while some other studies reported a greater growth reduction in smaller trees during droughts. We tested these hypotheses by comparing tree basal area increment (BAI), drought resistance (i.e., magnitude of growth decline during drought), and resilience (i.e., magnitude of growth recovery after drought) across five different age-classes in black pine (Pinus nigra Arn. ssp. salzmannii) forests in Spain. Our results showed that the BAI patterns, drought resistance, and resilience were strongly influenced by tree age-classes. In addition, the effect of climatic water balance (precipitation minus potential evapotranspiration) on BAI significantly varied among age-classes. The effect of water balance on BAI was lower for younger age-classes (1–39 years of age) compared to older age-classes. We observed a greater growth reduction (i.e., lower resistance) in older trees (>40 years of age) during droughts compared to younger trees (<40 years of age). However, all trees, irrespective of their ages, were able to recover the growth rates after the drought. In general, younger trees showed a greater capacity in recovering the growth rate (i.e., more resilient) than older trees. We detected no significant effects of stand basal area and stand density on BAI, drought resistance, and resilience. Overall, our results indicated that growth of older trees was more negatively affected during drought. Therefore, these older/larger trees can be selected for commercial thinning, or can be released from competition, which can minimize the potential impacts of future droughts in black pine forests in Spain.

    Avian regulation of crop and forest pests, a meta-analysis
    (Wiley, 2023-03-07) Monteagudo, Navila; Rey Benayas, José María; Andivia Muñoz, Enrique; Rebollo, Salvador
    Background: Birds have been shown to reduce pest effects on various ecosystem types. This study aimed to synthesize the effect of birds on pest abundance, product damage and yield in agricultural and forest systems in different environments. Our hypothesis is that birds are effective pest regulators that contribute to a reduction in pest abundance, enhancement of yield quality and quantity and economic profit, and that pest regulation may depend on moderators such as the type of ecosystem, climate, pest, and indicator (ecological or economic). Results: We performed a systematic literature review of experimental and observational studies related to biological control in the presence and absence of regulatory birds. We retained 449 observations from 104 primary studies that were evaluated through qualitative and quantitative analyses. Of the 79 studies with known effects of birds on pest regulation, nearly half of the 334 observations showed positive effects (49%), 46% showed neutral effects, and very few (5%) showed negative effects. Overall effect sizes were positive (mean Hedges’ d = 0.38 ± 0.06). A multiple model selection retained only ecosystem and indicator types as significant moderators. Conclusion: Our results support our hypothesis that there is a positive effect of avian control of pests for each analyzed moderator and this effect was significant for both ecological and economic indicators. Avian regulation of pests is a potential effective approach for environmentally friendly pest management that can reduce pesticide use regardless of the context of implementation.

    Forest structure drives the expected growth of Pinus nigra along its latitudinal gradient under warming climate
    (Elsevier, 2021-11-01) Candel Pérez, D.; Lucas Borja, M. E.; García-Cervigón del Rey, A. I.; Tíscar, P. A.; Andivia Muñoz, Enrique; Bose, Arun K.; Sánchez Salguero, R.; Camarero, J. J.; Linares, J. C.
    Droughts chronically alter resource availability in forest ecosystems. The increased frequency and severity of such extreme climate events challenge the acclimation potential of tree species especially across the droughtprone Mediterranean region. Pinus nigra is a widely distributed tree species in the Mediterranean region and considered vulnerable to extreme droughts. We used a 1000 km latitudinal gradient from northern Morocco to north-eastern Spain incorporating four regions (Edge-South, Core-South, Core-North and Edge-North) and including different P. nigra provenances. We aim to identify the climate and forest structure related drivers that influence tree radial growth (BAI, basal area increment). We developed statistical models for BAI by incorporating the potential effects of climate and forest structure (diameter and age distributions). Then, we forecasted the future growth of P. nigra forests during the 21st century considering the emission scenario A2 with an expected increase of +2.7 ◦C at the end of this century. Our results showed large variability across P. nigra populations in terms of environmental conditions, forest structure, and growth. The northernmost P. nigra populations, subjected to wetter and cooler conditions were those presenting the lowest BAI (4.9 cm2 ), whereas the southernmost P. nigra populations subjected to drier and warmer conditions presented the highest BAI values (11.5 cm2 ). Pinus nigra growth was enhanced by high spring precipitation, but this positive effect was probably modulated by forest structure. Temperature explained a higher proportion of the BAI variance than precipitation, with warmer summer conditions decreasing growth. Growth projections forecasted a decline in BAI (from 9.6 to 7.0 cm2 ) across all ecological regions starting around the mid-21st century but being lower in Edge-North populations compared to the other populations. Our study provides quantitative knowledge related to how P. nigra populations have been growing across four distinctive ecological regions. We also provide a forecasting tool that incorporates both climate and stand structure related information to project dynamics in tree populations.

    Evidence of non-stationary relationships between climate and forest responses: Increased sensitivity to climate change in Iberian forests
    (Wiley, 2019) Astigarraga, Julen; Andivia Muñoz, Enrique; Zavala, Miguel A.; Gazol, Antonio; Cruz-Alonso, Verónica; Vicente-Serrano, Sergio M.; Ruiz Benito, Paloma
    Climate and forest structure are considered major drivers of forest demography and productivity. However, recent evidence suggests that the relationships between climate and tree growth are generally non-stationary (i.e. non-time stable), and it remains uncertain whether the relationships between climate, forest structure, demography and productivity are stationary or are being altered by recent climatic and structural changes. Here we analysed three surveys from the Spanish Forest Inventory covering c. 30 years of information and we applied mixed and structural equation models to assess temporal trends in forest structure (stand density, basal area, tree size and tree size inequality), forest demography (ingrowth, growth and mortality) and above-ground forest productivity. We also quantified whether the interactive effects of climate and forest structure on forest demography and aboveground forest productivity were stationary over two consecutive time periods. Since the 1980s, density, basal area and tree size increased in Iberian forests, and tree size inequality decreased. In addition, we observed reductions in ingrowth and growth, and increases in mortality. Initial forest structure and water availability mainly modulated the temporal trends in forest structure and demography. The magnitude and direction of the interactive effects of climate and forest structure on forest demography changed over the two time periods analysed indicating non-stationary relationships between climate, forest structure and demography. Above-ground forest productivity increased due to a positive balance between ingrowth, growth and mortality. Despite increasing productivity over time, we observed an aggravation of the negative effects of climate change and increased competition on forest demography, reducing ingrowth and growth, and increasing mortality. Interestingly, our results suggest that the negative effects of climate change on forest demography could be ameliorated through forest management, which has profound implications for forest adaptation to climate change.
