“…To create an OTU table, all reads were mapped to OTUs using the usearch_global method (vsearch). OTUs that could be assigned to nematode genera allowed estimates of relative abundances of functional groups (Yeates et al, 1993). Reference sequences were first trimmed with forward and reverse primers using cutadapt (Martin, 2011).…”

“…This genus-level database was assembled to obtain a better indication of functional dissimilarity of the nematode community, as nematode species from the same genus tend to have similar ecological functions, especially in feeding behaviour (Yeates et al, 1993). One database consisted of the relative abundance data of all sequenced nematode OTUs, whereas the other contained relative abundance data of nematode genera based on the sequenced OTUs that could be assigned to nematode genus level.…”

“…Among soil biota, nematodes are the most abundant animals and perform key functions as bacterivores, fungivores, omnivores, predators and root herbivores (de Ruiter, Neutel, & Moore, 1995;Ferris, Bongers, & De Goede, 2001;Yeates, Bongers, Degoede, Freckman, & Georgieva, 1993), but their potential role in the success of rangeexpanding plant species is not yet fully understood (Morriën, Duyts, & van der Putten, 2012;Wilschut, Kostenko, Koorem, & van der Putten, 2018). Moreover, while root-feeding nematodes are well studied with respect to their role as agricultural pests (Nicol et al, 2011), their role in natural ecosystems has received less attention (De Deyn et al, 2003).…”

Current climate change has led to latitudinal and altitudinal range expansions of numerous species. During such range expansions, plant species are expected to experience changes in interactions with other organisms, especially with belowground biota that have a limited dispersal capacity. Nematodes form a key component of the belowground food web as they include bacterivores, fungivores, omnivores and root herbivores. However, their community composition under climate change‐driven intracontinental range‐expanding plants has been studied almost exclusively under controlled conditions, whereas little is known about actual patterns in the field. Here, we use novel molecular sequencing techniques combined with morphological quantification in order to examine nematode communities in the rhizospheres of four range‐expanding and four congeneric native species along a 2,000 km latitudinal transect from South‐Eastern to North‐Western Europe. We tested the hypotheses that latitudinal shifts in nematode community composition are stronger in range‐expanding plant species than in congeneric natives and that in their new range, range‐expanding plant species accumulate fewest root‐feeding nematodes. Our results show latitudinal variation in nematode community composition of both range expanders and native plant species, while operational taxonomic unit richness remained the same across ranges. Therefore, range‐expanding plant species face different nematode communities at higher latitudes, but this is also the case for widespread native plant species. Only one of the four range‐expanding plant species showed a stronger shift in nematode community composition than its congeneric native and accumulated fewer root‐feeding nematodes in its new range. We conclude that variation in nematode community composition with increasing latitude occurs for both range‐expanding and native plant species and that some range‐expanding plant species may become released from root‐feeding nematodes in the new range.

“…). Under the assumption of phylogenetic niche conservatism, closely related species are predicted to be ecologically similar (see Anacker and Strauss ) and thus compete strongly. Within this ecophylogenetic framework, competitively structured communities would therefore favor the coexistence of more distantly related species—phylogenetic overdispersion—because of weaker competitive interactions between species.…”

Abstract. Competitive exclusion is most likely when there are large differences in competitive ability and the strength of competitive interactions between species is high, but predicting competitive outcomes is not straightforward. Assuming a trade-off between competitive ability and ecological generalism, we would predict larger competitive differences between species with different niche widths. Community phylogenetic theory predicts that competition will be stronger among more closely related species, assuming that phylogenetic distance reflects ecological similarity. We would therefore expect the probability of competitive exclusion to be highest among closely related species with different niche widths. Here, we assess how well differences in niche width and phylogenetic distance correlate with co-occurrences among 34 species of Cyperaceae (sedges) in the eastern Canadian subarctic. The Cyperaceae is a species-rich family, with many species sharing similar niches and environmental tolerances, making it a model clade for evaluating the importance of niche width differences and phylogenetic distances on co-occurrence. Consistent with both hypotheses, we found that higher co-occurrence scores correlated with species pairs that were distantly or only intermediately related and that had similar niche widths. Furthermore, we show that this correlation is stronger when considering only more recently diverged species pairs and that there is a triangular relationship between phylogenetic distance and species co-occurrence, suggesting that distantly related species might have both strong and weak competitive interactions. Using co-occurrence as a proxy for competitive outcomes, our results support both a negative correlation between phylogenetic distance and strength of competitive interactions, and a trade-off between niche width and competitive ability.

1. Little attention has been paid to phylogenetic diversity during restoration initiatives. Because plant phylogenetic distance can be a surrogate for functional diversity, its consideration could foster the restoration of degraded areas.2. This study investigates the influence of species richness and phylogenetic relatedness during early restoration of a riparian forest located between the Atlantic Forest and semi-arid ecosystems in NE Brazil. The restoration experiment was established along a perennial stream in Monte Alegre, RN, investigating the significance of species richness and phylogenetic diversity for sapling survival and growth of the restored communities.3. We used phylogenetic information on 47 tree species naturally occurring at the study site. The resulting phylogenetic tree had a basal node with three major clades. To implement the experiment, three species from each clade were randomly selected, resulting in nine species (from five families). We defined five levels of diversity: (i) no planting, (ii) monoculture, (iii) three phylogenetically related species (same clade), (iv) three phylogenetically distant species (different clades) and (v) nine species. The experiment consisted of 96 (12 m × 10 m) plots established along the two margins of the stream. Overall, 1656 saplings (20-50 cm) were planted in September 2015 (184 per species). We tested whether the survival and growth of saplings are influenced by the number of species planted and phylogenetic distance among them. 4. We assessed plant mortality and growth during two consecutive years (2016 and 2017). Survival was lower but relative growth was higher for plants near the stream. After controlling for differences in initial size, plots with phylogenetically distant species produced significantly taller plants, but only when occurring near the stream. Diversity treatments did not influence plant survival, while initial size determined plant survival and growth. 5. Our findings show that greater phylogenetic distance led to increased plant growth, probably, because of the presence of functionally divergent species thatThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
