Long-term effects of intercropping on multi-trophic structure and bio-thermodynamic health of mixed Eucalyptus-native tree plantations

1. The intercropping approach of Eucalyptus and native trees has been widely recommended, as an ideal replacement for monoculture Eucalyptus plantations (EUs), to ameliorate global biodiversity loss and mitigate environmental change. However, both suitable native tree species and the best intercropping ratio between Eucalyptus and native trees have not been determined. 2. To fill this gap, a four-level intercropping gradient of Eucalyptus urophylla planted with eight native tree species was set up (i.e., 20%NS, 30%NS, 40%NS, 50%NS), monitored and compared to a monoculture E. urophylla plantation (EU) and a randomly mixed plantation of nine native tree species (NS) in southern China. 3. The results showed that the intercropping ratio of Eucalyptus and native trees had a long-term effect on tree layer structure and health status and a cascading effect on the thermodynamic health state of soil microbes. Shade-tolerant woody species are more suitable for intercropping with Eucalyptus. Intercropping plantations with not less than 30% native trees were more favorable for long-term survival and growth of both planted Eucalyptus and native trees and provided much more favorable conditions for the natural immigration of other native trees, which leads to a healthy plant community with significantly higher eco-exergy compared to EU. The initial mixing ratio between Eucalyptus and high diversity native trees affected soil fertility through its long-term effects on the biodiversity and bio-thermodynamic state of trees and soil microbes. 4. Synthesis and applications. Our results highlight the long-term positive effect of the intercropping ratio of Eucalyptus and high diversity native trees on multi-trophic biodiversity conservation, bio-thermodynamic health development, and soil fertility conservation. In the conversion of monoculture Eucalyptus plantations (EU) to multi-species plantations, it is recommended to mix more than 30% native tree species that have different ecological niches with Eucalyptus.

FIGURE 1. Phylogram generated for Coniella species from ML and BI analyses based on a combined dataset of ITS, LSU, and tef1-α sequences. The tree is rooted with Melanconiella sp. (CBS110385). Bootstrap support values for ML ≥ 65 % and Bayesian posterior probabilities (PP) ≥ 0.95 are shown at the nodes. The strain from the current study is in red. All ex-type strains are in bold black. Some branches were shortened to fit them to the pages, and these are indicated by two diagonal lines with the number of times a branch was shortened indicated next to the lines.

Response of 25-day old Eucalyptus globulus to elevated CO2

Increasing [CO2] may influence commercial crop and timber yield. While selection of genotypes sensitive to elevated [CO2] (e[CO2]) appears possible in agricultural crops, there is limited evidence for genotype-by-CO2 (G×CO2) interactions in commercial tree species. We examined [CO2] responsiveness in 124 open-pollinated Eucalyptus globulus subspecies globulus (E. globulus) families with the aim of assessing whether G×CO2 interactions are detectable in seedlings for early-age screening. Plants were grown in ambient (a[CO2]; ~405 μmol mol-1) and e[CO2] (640 μmol mol-1) and harvested 25 days after germination. Total, shoot and root dry weights were determined for each plant. Carbon isotopic discrimination against 13C (Δ13C) was determined at the family level. We observed highly significant (p<0.0001) increases in mean total, shoot, and root dry weights. Mixed-model equations were used to estimate the main and interaction effects of the G×CO2 for each mass trait. The main effects from the mixed model output ([CO2] and individual-tree effects) were significant for all traits. However, [CO2]-by-individual tree interactions were non-significant for all traits, indicating little G×CO2 interaction. A secondary aim was to examine the correlation between greenhouse and mature-age growth from breeding trials that use common families conducted under ambient [CO2]. These correlations were non-significant, suggesting early growth is not necessarily indicative of later-age responses. Our results suggest that while early growth of E. globulus is enhanced under e[CO2], genotypes respond relatively uniformly to e[CO2] and little opportunity exists for seedling-based selection at the population level based upon the response of plants during the first weeks of growth.
