Dataset of Rainy years counteract negative effects of drought on taxonomic, functional, and phylogenetic diversity: resilience in annual plant communities
<p>Data used in the article: </p> <p><strong>Rainy years counteract negative effects of drought on taxonomic, functional, and phylogenetic diversity: resilience in annual plant communities</strong></p> <p><strong>Abstract</strong></p> <p>1- Climate models forecast changes in the amounts and distribution of rain, which may affect ecosystems worldwide, especially in drylands where water is already the limiting factor for plant life. Annual plant communities are common in drylands where they can complete their entire life cycle during the rainy period while avoiding the dry season. Moreover, seed dormancy allows them to disperse over time by remaining in the seed bank for long periods. However, the extent to which these communities will be able to tolerate increasing drought is uncertain.</p> <p>2- We performed a five-year rainfall reduction treatment under field conditions and determined its effects on annual plant communities in a Mediterranean gypsum ecosystem. We assessed the taxonomic, functional, and phylogenetic diversity of these communities each year for five years.</p> <p>3-The taxonomic and functional diversity decreased under the rainfall reduction treatment whereas the phylogenetic diversity increased. Moreover, the relative importance of species with drought-resistant functional designs increased in the community assemblages. However, after a rainy season with above average rainfall, all of the diversity values recovered completely even under the rainfall reduction treatment.</p> <p>4- Our results provide important insights into the responses of these plant communities under a climate change scenario, where they indicate high losses of diversity during drought events but rapid recovery in milder years.</p> <p><em>Synthesis</em> Our findings highlight the great resilience of annual plant communities in drylands, which may allow them to tolerate increased drought under the present climate change scenario.</p>
Community level phylogenetic diversity does not differ between rare and common lineages across tallgrass prairies in northern Great Plains
<p class="MsoNormal">In some cases, rare lineages provide resistance to invasions, serve as keystone species, and contribute unique functional or phylogenetic diversity to their communities. In other cases, rare species may be functionally redundant with common species and do not significantly contribute to phylogenetic diversity. How rare and common species coexist and contribute to local species pools may depend upon attributes of their communities and remains an open question in ecology. Niche differentiation has served as an explanation for species coexistence, and phylogenetic relatedness provides a means to approximate how ecologically similar species are to each other. To explore the contribution of rare species to community phylogenetic diversity, we sampled twenty-one plant communities across the Prairie Coteau ecoregion, home of the largest tracts of untilled northern tallgrass prairie and of high conservation concern. We used breakpoint analysis through iterative addition of less abundant species to the phylogenetic tree for each community. We also assessed the phylogenetic signal of abundance classes using Blomberg's K statistic and calculated the phylogenetic similarity between rare and common species using a phylogenetic beta diversity metric (D<sub>nn</sub>). To estimate the phylogenetic structuring of these prairie communities, we calculated two common metrics that capture evolutionary relatedness between species (MPD, and MNTD) and examine the correlation between these metrics and species richness. Overall, we found rare species do not contribute higher levels of phylogenetic diversity than more common species in the Prairie Coteau ecoregion. Eight of 21 communities had significant breakpoints, where the addition of a less common species resulted in a shift in phylogenetic diversity, with only four communities having an increasing trend for the rarest species. Phylogenetic signal for abundance was low and unsignificant across 18 communities, while four sites did show significant low phylogenetic signal. We additionally found our communities had lower phylogenetic diversity than expected from the regional species pool. Finally, we found weak to no correlation when using MPD and MNTD. Our results indicate niche differentiation does not explain rare species persistence in tallgrass prairies. We found species were more closely related than expected from random community assembly, suggesting high functional redundancy within this system. This is promising for the long term viability of this ecosystem, but only insofar as enough species remain in the system to create redundancy. With ongoing biodiversity loss, it is essential we understand the role rare species play in their communities. Phylogenetic diversity could be an important tool for researchers and managers to utilize for conservation of critically threatened systems such as tallgrass prairies.</p>
Data from: Mycorrhizal symbiosis increases plant phylogenetic diversity and regulate community assembly
<p>The intricate mechanisms shaping plant diversity and community composition are the cornerstone of ecological understanding. Yet, the role of mycorrhizal symbiosis, the fundamental partnership between fungi and plant roots, in influencing community composition has often been underestimated. Here, we use extensive species survey data from 1,315 terrestrial ecosystem sites to elucidate the influence of mycorrhizal symbiosis on plant phylogenetic diversity and its implications for community assembly processes. Our findings demonstrate that increasing mycorrhizal symbiotic potential leads to greater phylogenetic dispersion within plant communities. Furthermore, we unveil a distinct dichotomy in the assembly processes governed by mycorrhizal status. Mycorrhizal species predominantly influence deterministic processes, suggesting a role in niche-based community assembly. Conversely, non-mycorrhizal species exert a stronger influence on stochastic processes, highlighting the importance of random events in shaping community structure. These results underscore the crucial but often hidden role of mycorrhizal symbiosis in driving plant community diversity and assembly. This study provides valuable insights into the complex mechanisms shaping ecological communities and the way for more informed conservation and management practices that acknowledge the complex interplay between symbiosis and ecological community dynamics.</p>
