“…PD incorporates the phylogenetic difference between taxa, which is useful for evaluating the potential features of taxa to adapt in changing environments, as it is based on evolutionary relationships between taxa (Faith, ; Winter, Devictor, & Schweiger, ). Compared to TD, both FD and PD have only recently been included in soil nematode research (Li et al, ; Mulder & Maas, ), despite that they might help in understanding potential consequences of land conversion.…”

Anthropogenic conversion of natural to agricultural land reduces aboveground biodiversity. Yet, the overall consequences of land‐use changes on belowground biodiversity at large scales remain insufficiently explored. Furthermore, the effects of conversion on different organism groups are usually determined at the taxonomic level, while an integrated investigation that includes functional and phylogenetic levels is rare and absent for belowground organisms. Here, we studied the Earth's most abundant metazoa—nematodes—to examine the effects of conversion from natural to agricultural habitats on soil biodiversity across a large spatial scale. To this aim, we investigated the diversity and composition of nematode communities at the taxonomic, functional, and phylogenetic level in 16 assemblage pairs (32 sites in total with 16 in each habitat type) in mainland China. While the overall alpha and beta diversity did not differ between natural and agricultural systems, all three alpha diversity facets decreased with latitude in natural habitats. Both alpha and beta diversity levels were driven by climatic differences in natural habitats, while none of the diversity levels changed in agricultural systems. This indicates that land conversion affects soil biodiversity in a geographically dependent manner and that agriculture could erase climatic constraints on soil biodiversity at such a scale. Additionally, the functional composition of nematode communities was more dissimilar in agricultural than in natural habitats, while the phylogenetic composition was more similar, indicating that changes among different biodiversity facets are asynchronous. Our study deepens the understanding of land‐use effects on soil nematode diversity across large spatial scales. Moreover, the detected asynchrony of taxonomic, functional, and phylogenetic diversity highlights the necessity to monitor multiple facets of soil biodiversity in ecological studies such as those investigating environmental changes.

“…Specifically, NRI is the average phylogenetic relatedness between all pairwise combinations of taxa, whereas NTI indicates the mean phylogenetic relatedness between each taxon and its nearest relative. NRI values in our analysis quantify the overall clustering of plentiful and behaviorally dominant species on the phylogeny, whereas NTI is more sensitive to the phylogenetic structure near the terminal nodes of the phylogeny, and measures the extent of terminal clustering, independently of the level of deep clustering in the tree (Li et al, ; Webb, Ackerly, & Kembel, ; Webb, Ackerly, McPeek, & Donoghue, ). NRI and NTI were first used in community ecology for comparing whether species in a given community can be regarded as a random set of species.…”

“…We assessed the significance of these parameters through measures of the standardized effect size (SES effect), which describes the difference between phylogenetic distances in plentiful and dominant species in the observed phylogeny versus randomly generated null phylogenies (999 random draws). To perform this, we used the “shuffle distance matrix labels” null model method, which shuffles species labels across all taxa included in the phylogenetic tree (Li et al, ; Webb et al, ). Positive SES values of NRI or NTI indicate phylogenetic clustering with lower phylogenetic distances among survey species (Li et al, ).…”

“…To determine whether hummingbird species that share a particular trait (e.g., plentifulness and behavioral dominance) are more closely related than expected by chance, we calculated two metrics: (a) (Li et al, 2014;Webb, Ackerly, & Kembel, 2008;Webb, Ackerly, McPeek, & Donoghue, 2002). NRI and NTI were first used in community ecology for comparing whether species in a given community can be regarded as a random set of species.…”

Body mass as a supertrait linked to abundance and behavioral dominance in hummingbirds: A phylogenetic approach

Body mass has been considered one of the most critical organismal traits, and its role in many ecological processes has been widely studied. In hummingbirds, body mass has been linked to ecological features such as foraging performance, metabolic rates, and cost of flying, among others. We used an evolutionary approach to test whether body mass is a good predictor of two of the main ecological features of hummingbirds: their abundances and behavioral dominance. To determine whether a species was abundant and/or behaviorally dominant, we used information from the literature on 249 hummingbird species. For abundance, we classified a species as “plentiful” if it was described as the most abundant species in at least part of its geographic distribution, while we deemed a species to be “behaviorally dominant” when it was described as pugnacious (notably aggressive). We found that plentiful hummingbird species had intermediate body masses and were more phylogenetically related to each other than expected by chance. Conversely, behaviorally dominant species tended to have larger body masses and showed a random pattern of distribution in the phylogeny. Additionally, small‐bodied hummingbird species were not considered plentiful by our definition and did not exhibit behavioral dominance. These results suggest a link between body mass, abundance, and behavioral dominance in hummingbirds. Our findings indicate the existence of a body mass range associated with the capacity of hummingbird species to be plentiful, behaviorally dominant, or to show both traits. The mechanisms behind these relationships are still unclear; however, our results provide support for the hypothesis that body mass is a supertrait that explains abundance and behavioral dominance in hummingbirds.
