Data from: Forest degradation limits the complementarity and quality of animal seed dispersal
<p><span>Forest degradation changes the structural heterogeneity of forests and species communities, with potential consequences for ecosystem functions including seed dispersal by frugivorous animals. While the quantity of seed dispersal may be robust towards forest degradation, changes in the effectiveness of seed dispersal through qualitative changes are poorly understood. Here, we carried out extensive field sampling on the structure of forest microhabitats, seed deposition sites, and plant recruitment along three characteristics of forest microhabitats (canopy cover, ground vegetation, deadwood) in Europe's last lowland primeval forest (Białowieża, Poland). We then applied niche modelling to study forest degradation effects on multi-dimensional seed deposition by frugivores and recruitment of fleshy-fruited plants. Forest degradation was shown to (1) reduce the niche volume of forest microhabitat characteristics by half, (2) homogenize the spatial seed deposition within and among frugivore species, and (3) limit the regeneration of plants via changes in seed deposition and recruitment. Our study shows that the loss of frugivores in degraded forests is accompanied by a reduction in the complementarity and quality of seed dispersal by remaining frugivores. In contrast, structure-rich habitats, such as old-growth forests, safeguard the diversity of species interactions, forming the basis for high-quality ecosystem functions.</span></p>
Relationship between genome-wide and MHC class I and II genetic diversity and complementarity in a nonhuman primate
<p>Although mate choice is expected to favor partners with advantageous genetic properties, the relative importance of genome-wide characteristics, such as overall heterozygosity or kinship, versus specific loci, is unknown. To disentangle genome-wide and locus-specific targets of mate choice, we must first understand congruence in global and local variation within the same individual. This study compares genetic diversity, both absolute and relative to other individuals (e.g., complementarity), assessed across the genome to that found at the major histocompatibility complex (MHC), a hyper-variable gene family integral to immune system function and implicated in mate choice across species. Using DNA from 22 captive olive baboons (<em>Papio anubis</em>), we conducted double digest restriction-site associated DNA sequencing to estimate genome-wide heterozygosity and kinship and sequenced two class I and two class II MHC loci. We found that genome-wide diversity was not associated with MHC diversity, and that diversity at class I MHC loci was not correlated with diversity at class II loci. Additionally, kinship was a significant predictor of the number of MHC alleles shared between dyads at class II loci. Our results provide further evidence of the strong selective pressures maintaining genetic diversity at the MHC in comparison to other randomly selected sites throughout the genome. Furthermore, our results indicate that class II MHC disassortative mate choice may mediate inbreeding avoidance in this population. Our study suggests that mate choice favoring genome-wide genetic diversity is not always synonymous with mate choice favoring MHC diversity, and highlights the importance of controlling for kinship when investigating MHC-associated mate choice.</p>

Data from: Both the selection and complementarity effects underpin the effect of structural diversity on aboveground biomass in tropical forests
<p><strong>Aim:</strong> Despite mounting empirical evidence regarding the positive effects of forest structural diversity (STR<sub>DIV</sub>) on forest functioning, the underlying biotic mechanisms and controlling abiotic factors remain poorly understood. This study provides the first assessment of the interactive effects of STR<sub>DIV</sub> and diversity in species and functional traits on aboveground biomass (AGB) in natural forests in West and East Africa.</p> <p><strong>Location: </strong>West and East Africa</p> <p><strong>Time period: </strong>2014-2020</p> <p><strong>Major taxa studied:</strong> Woody plants</p> <p><strong>Methods:</strong> Using data from 276 plots and 7993 trees of 207 species distributed across various types of natural forests and major climatic zones of Africa, linear mixed-effects and structural equation models, we have evaluated how alternative causal relationships between STR<sub>DIV</sub> and taxonomic and functional diversity attributes influence AGB, while accounting for the effects of environmental covariates. We also assessed the consistency of these relationships across floristically and environmentally homogenous forest types.</p> <p><strong>Results:</strong> We found that the positive effects of STRDIV on AGB were underpinned by both the community-weighted mean (CWM) of trait values (selection effects) and species richness (niche complementarity), but the relative importance of these effects varied depending on forest types. Across the forest types, STR<sub>DIV </sub>primarily mediated the effects of CWM of traits and species richness on AGB. We also found that STR<sub>DIV</sub>–AGB relationships were constrained by resource (water and nutrient) availability.</p> <p><strong>Main conclusions:</strong> Our findings provide novel insights into the role of functional traits as key determinants of the effects of STR<sub>DIV</sub> on AGB in tropical forests. We suggest that forest management and climate change mitigation strategies aimed at conserving biodiversity and fostering biomass storage through increased STR<sub>DIV </sub>should focus on maintaining high levels of functionally dominant species while also increasing tree species diversity.</p>

Shifts in dominance and complementarity between sessile oak and beech along ecological gradients
<p>Whether tree species benefit from growing in a mixed forest depends on the relative importance of positive versus negative interactions, which varies according to abiotic conditions. In mixture with sessile oak (Quercus petraea (Matt.) Liebl.), European beech (Fagus sylvatica L.) is often competitively dominant. Sessile oak, however, is more resistant to water deficit stress. Under water-limiting conditions, facilitation or even competition exerted by oak may gain in importance.</p> <p>We investigated the relative importance of dominance and complementarity in 7 triplets of pure and mixed forests in Belgium's temperate oceanic climate. We analysed ring width data of 145 oaks and 138 beech trees along three distinct gradients: a spatial (i) and a temporal (ii) water availability gradient and a temporal gradient in growing conditions (iii). Gradient (ii) was represented by a precipitation variable, obtained by defining a large set of candidate climate variables over variable time frames, narrowed down using a species and site-specific lasso model. Growing conditions on a temporal gradient (iii) were represented by standardized tree growth. Two sets of linear mixed-effects models were used. Growth models assess mixing effects on ring width along gradients (i) and (ii). Mixing index models test for all three gradients how they affect the relative difference in average ring width of trees in mixed and pure stands.</p> <p>Beech trees grew faster than oak trees, and mixing further increased beech growth while decreasing oak growth, except on drier sites where the negative effect on oak growth disappeared. Low precipitation years, in contrast, reduced the beneficial effect of mixing on beech. In years of low growth, the positive mixing effect on beech growth was reinforced, and the negative mixing effect on oak growth decreased.</p> <p>Synthesis. Mixing buffered against growth limitations in general, though this depends on the nature of the limitation and the gradient over which it is measured. On dry sites, competitive dominance of beech was replaced by higher complementarity between species. During dry years, however, oak did not profit from a decreased mixing benefit of beech.</p>
Temporal stability of productivity is associated with complementarity and competitive intensities in intercropping
Year to year stability in crop production is a crucial aspect of feeding a growing global population. Evidence from natural ecosystems shows that increasing plant diversity generally increases the temporal stability of productivity; however, we have little knowledge of the mechanisms by which diversity affects stability. In fact, understanding the drivers of stability is a major knowledge gap in our understanding of biodiversity and ecosystem function in general. We varied resource inputs into crop monocultures and intercropping of maize/pea and maize/rapeseed for three years in field experiments to create a wide range of values for temporal stability, complementarity effects, selection effects, competition, and facilitation. We correlated whole-system temporal stability in productivity with these values and the stability of competitively subordinate species and competitively dominant species in the intercrops. We then used structural equation modeling (SEM), which combines complex path models with latent variables, to estimate how interspecific interactions for water, nitrogen, and phosphorus affected the relationships between stability and these values. Intercropping treatments did not increase stability, but the wide range of stability created by our experiments allowed us to explore the relationship of many factors with stability. Complementarity correlated positively with the temporal stability of grain yield and aboveground biomass, suggesting that either facilitative interactions or niche partitioning shifted over time in ways that promoted stability. Furthermore, the temporal stability of total productivity of intercropping relied most on the stability of more productive species. However, facilitation tested by relative interaction index (RII) independently did not correlate with stability, but the temporal stability of the whole system increased as the competitive effects of competitively dominant species (pea and rapeseed) on competitively subordinate species (maize) decreased, and was highest when these competitive effects were virtually zero. SEM indicated that as competition for soil nitrogen from competitively dominant species on competitively subordinate species decreased, the overall temporal stability of whole-system aboveground biomass increased. This stability then led to greater stability in grain production. Our findings indicate that complex shifts in complementarity and competitive intensities are likely to be key mechanisms that maintain temporal stability in species-diverse agriculture, and potentially in natural systems.
Data for: Wild bee communities benefit from temporal complementarity of hedges and flower strips in apple orchards
<p><span>1. </span>Wild bees importantly pollinate both crop and wild plants. Yet, in <span>intensive agricultural landscapes, wild bees are rare due to resource limitations of nectar and pollen. Flower strips and hedges are often used as resource enhancements for wild bees to overcome this shortage, but provide floral resources only during specific time periods. To sustain diverse and stable bee communities, bee-attractive flowers need to be available during the entire growing season. This may be achieved by combining flower strips and hedges to complement each other and provide continuous floral resources. </span></p> <p><span>2. </span><span>Over three subsequent years, we compared the phenology of flower and wild bee communities in perennial flower strips, hedges and improved hedges (complemented with a sown herb layer) in conventional apple orchards in Southern Germany, a pollination-dependent crop-system. </span></p> <p><span>3. </span><span>Hedges provided floral resources in the early season while the flower strips took over later in the season. </span></p> <p><span>4. </span><span>Bees visited the hedges mostly from March to June, whereas they visited the flower strips from June to August (first year), and in the second year already from April onwards. Flower strips were visited with an overall higher abundance and species richness than the improved and not modified hedges. </span></p> <p><span>5. </span><span>Synthesis and application</span><span>: For enhancing wild bees in intensive apple orchards, hedges and perennial flower strips are complementary in providing flower resources. Yet, flower strips bloom more constantly and during periods of flower scarcity, and thus attract more bees than hedges. Perennial flower strips of different age classes should be preferred over annual strips, at best in a network with some well-maintained hedges, as perennial flower strips of different age attract different bee communities and thus potentially a higher bee diversity on the landscape level. </span></p>
