Understanding the role of different drivers in current patterns of carbon stock and uptake is critical to predicting tropical forest responses to environmental changes. That said, taxonomic identity and evolutionary relatedness among <em>taxa</em> may synthesize intrinsic functional characteristics and provide insight into these patterns. Here we investigated the main ecological drivers (taxonomic vs. environmental effects) and the evolutionary legacy on the expression of two important variables: carbon stock and carbon uptake. The dataset used are composed by tropical forests sites located in the southeast of Brazil along a climatic gradient including evergreen forests, semideciduous forests and deciduous forests. Relying on forest inventory data from 30 tropical forest sites (33.86 ha), we calculated individual tree carbon stocks and obtained two variables at the population level (species <em>per</em> site): average carbon stock (ton/ha) and average carbon uptake (ton/ha/year). These variables were used joint to phylogenetic trees and analysis to evaluate the main factors explained the variables variation and the evolutionary fingerprint on them. Variations in carbon stock and uptake by individual trees were mostly determined by taxonomic identity (28.7% and 26.7%, respectively) rather than environmental factors (7.1% and 8.9%, respectively), but evolutionary relatedness did not predict similarity among species. Our results indicate that the ability of species to store and absorb carbon depend on their intrinsic characteristics, although these are not shared among closely related <em>taxa</em>. Climate projections predict the loss of species unable to adapt to novel conditions, which, in light of our results, could impact tropical carbon dynamics. Although evolutionary relatedness does not predict similarity in terms of function at the scale of our study (suggesting lability of traits related to carbon storage), species losses indicate that environmental changes are beyond species’ ability to adapt to changes.</div></div>","PeriodicalId":55564,"journal":{"name":"Acta Oecologica-International Journal of Ecology","volume":"126 ","pages":"Article 104065"},"PeriodicalIF":1.3,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five, five, and six plots were randomly selected from each forest restoration type in Yimeng Mountain area in Northern China. Forest restoration type significantly influenced acid phosphatase kinetics. Acid phosphatase activity and acid phosphatase activity dissimilarity was higher in natural secondary forests than those in oriental oak plantations, which in turn were higher than those observed in black pine plantations. The difference between natural secondary forests and black pine plantations was significant. Moreover, the heterogeneity of soil acid phosphatase activity between the natural secondary forests and the two plantations was significantly higher than that between the two plantations. Forest restoration type did not significantly influence the potential maximum activity (<em>V</em>_max), half-saturation constant (<em>K</em>_m), or catalytic efficiency (<em>V</em>_max/<em>K</em>_m) of acid phosphatase. Ammonium nitrogen and available phosphorus content significantly influenced acid phosphatase kinetics, explaining 61.9% of the variation in acid phosphatase activity under different substrate concentrations in the three forest restoration types. <em>V</em>_max was positively influenced by available phosphorus content. The <em>K</em>_<em>m</em> value was positively influenced by total carbon content. Natural secondary forests showed better soil acid phosphatase kinetics than the native oriental oak plantations, which were better than those in the introduced black pine plantations, possibly due to the higher ammonium nitrogen and available phosphorus content.

Building on a previous study which found increased stem volume in genotypic mixtures, we measured crown characteristics, using a drone-based LiDAR, in genetic mixtures of loblolly pine in Virginia and North Carolina to test for: (1) aboveground spatial niche partitioning and (2) if this partitioning was associated with greater stem volume. Overall, we found no evidence that differences in crown sizes by ideotype led to aboveground spatial niche partitioning, resulting in greater overall crown size or stem volume when grown in mixture. Instead, genotypic mixtures overall, as opposed to genotypic monocultures, consistently had greater crown area, crown volume, and stem volume. Additionally, competition intensity decreased under genetic mixtures despite that these conditions led to greater overall stem and crown sizes than genotypic monocultures. No increase in aboveground spatial partitioning or individual-tree LAI in genotypic mixtures suggests greater radiation-use efficiency. Increases in radiation-use efficiency are primarily driven by belowground resource acquisition which suggests these mixtures may be capable of greater belowground resource exploitation.

Here, we assessed the contribution of rare and common species to the functional diversity of forest bird communities in a landscape dominated by oil palm plantations. We sampled birds in plantations and forest fragments in the eastern Amazon, Brazil. A total of 232 bird species were recorded, 198 in the fragments and 53 in the plantations. We calculated a rarity index for each species occurring in forest fragments, combining local abundance, geographic range, and habitat specificity. We calculated functional richness (FRic), functional originality (FOri), functional specialization (FSpe), and community-weighted trait means (CWM), and then compared these metrics between forest and plantation communities across three scenarios: 1) total species <em>pool</em> recorded in forest <em>versus</em> plantation, 2) removal of the rarest species, and 3) removal of common species. Removal of rare species increased functional diversity but decreased functional redundancy. Conversely, removal of common species decreased FOri and FSpe values, demonstrating that common forest bird species make unique functional contributions.

Palms generally have long leaf durability, which can reduce parasite cadaver loss by foliar abscission and increase cumulative spore dispersal.
