'… the most insightful finding by Zhu et al. was that only field mixtures allowed for identification of traits were predictive future species abundance and persistence …'. Alternatively, experiments allow manipulative control a limited number factors under realistic natural conditions. However, environmental conditions are unaccounted for, making replication difficult, which often results in contradictory evidence. Hence, may be unquestionably but also unlikely to consistently replicable, with being contingent both on location time due such as variation soil biota or differences precipitation among years between sites. Plant physiology ecology delve into study trade-offs. For scientist designing an experiment, choice vs common garden poses fundamental its own intrinsic Many individual studies have illustrated limitations pot experiments, recent (2024; https://doi.org/10.1111/nph.20160), published New Phytologist, showcases these trade-offs at particularly large scale (64 different species) interesting context (exotic native species). The authors grew plants each 64 individually pots compared exotic mixes same planted field. found generally confirmed expectations, only, not one pots. without limitations: comparison grown presented some caveats. It remains unclear whether any difference - absence could competition experiment other factors. We know tend outperform natives scenarios (van Kleunen al., 2010), those advantages sometimes evident certain conditions, typically disturbance (Jauni 2015; Xiao 2016; Montesinos, 2022), when resources abundant increasing (Davis 2000; Zhang 2022; Arias 2023) or, alternatively, low, experience stress (Funk & Vitousek, 2007; Santamarina 2022). is possible observed more competitive experienced cannot discard involving mix similar would resulted results. least previous experimental designs factor reducing trait exotics (Blumenthaal Hufbauer, 2007). This suggests problem might al.'s rather associated experiments. Perhaps (specific leaf area (SLA), plant height, aboveground biomass). Field showed overall persistent than natives, perennials annuals. These agree expectations native–exotic interactions, shown how can detect able discern (Leffler 2014). Still, few comparisons, meta-analysis Leffler (2014) provide integrative view cannot, however, direct evidence way single comparing simultaneously can. therefore comforting see verifying our theoretical assumptions yet it concerning recognize missing so much.

Differences between introduced and native grassland species revealed by responses to prolonged drought

Abstract Introduced species are a typical feature of modern plant communities and experience environmental challenges alongside native species, though introduced often hypothesized to be functionally distinct. Changes in the environment may reveal distinct responses change for components communities. We tested differences community composition California grasslands collected during period severe drought. Sampling was conducted across serpentine soils, which resilient against colonization by maintain diverse assemblages, heavily invaded non-serpentine soils. On dominated there no relationship between climatic variables over survey period. compositional were significantly associated with precipitation. In particular, component soils only weakly correlated current year precipitation did not differ from null contrast, retained strong associations on both soil types. identified three Eurasian grasses, Bromus hordeaceus , Elymus caput-medusae Avena fatua as greatest contributors These analyses suggest that majority this drought manifested within species. Our results consistent hypothesis adapted low-stress, high-competition conditions will substantial changes under drought, while high-stress, low-competition exhibit greater resilience.
