Alternating regimes of shallow and deep-sea diversification explain a species-richness paradox in marine fishes
<p>The deep sea contains a surprising diversity of life, including iconic fish groups such as anglerfishes and lanternfishes. Still, <span class="ins cts-1">> 65%</span><span class="del cts-1"></span> of marine teleost fish species are restricted to the photic zone < 200 m, which comprises less than 10% of the ocean's total volume. From a macroevolutionary perspective, this paradox may be explained by three hypotheses: 1) shallow-water lineages have had more time to diversify than <span class="PI"></span>deep-sea<span class="PI"></span> lineages, 2) shallow-water lineages have faster rates of speciation than <span class="PI"></span>deep-sea<span class="PI"></span> lineages, or 3) <span class="PI"></span>shallow-to-deep sea transition rates limit <span class="PI"></span>deep-sea<span class="PI"></span> richness. Here we use phylogenetic comparative methods to test among these three non<span class="ins cts-1">-</span>mutually exclusive hypotheses. While we found support for all hypotheses, the disparity in species richness is better described as the uneven outcome of alternating phases that favored shallow or deep diversification over the past 200 million y. Shallow marine teleosts became incredibly diverse 100 <span class="del cts-1">million years</span><span class="del cts-1"> ago</span> during a period of warm temperatures and high sea level, suggesting the importance of reefs and epicontinental settings. Conversely, <span class="PI"></span>deep-sea<span class="PI"></span> colonization and speciation were favored during brief episodes when cooling temperatures increased the efficiency of the ocean's carbon pump. Finally, <span class="PI"></span>time-variable<span class="PI"></span> ecological <span class="PI"></span>filters limited shallow-to-deep colonization for much of teleost history, which helped maintain higher shallow richness. A pelagic lifestyle and large jaws were associated with early <span class="PI"></span>deep-sea<span class="PI"></span> colonists, while a demersal lifestyle and a tapered body plan were typical of later colonists. Therefore, we also suggest that some hallmark characteristics of <span class="PI"></span>deep-sea<span class="PI"></span> fishes evolved prior to colonizing the deep sea.</p>
Data for: Mechanisms of fire-maintained plant species diversity in species-rich wet pine savannas
<p><span>Temperate savannas and grasslands maintained by frequent, low-intensity disturbances such as fire contain among the most species-rich plant communities in the world. Precisely how these disturbances maintain such high fine-scale diversity is poorly understood. This study examined the effects of the frequency of simulated fire (clipping combined with litter removal) and the relative importance of recruitment and survival on species diversity and trait and species composition at each of two pine savannas in southeastern Mississippi (USA) that had not been recently burned. Ten 2 </span><span>×</span><span> 2 m plots at each site were clipped/cleared annually from 2014 to 2019 and again in spring 2021 (annual frequency). The other 10 clipping plots were not clipped from 2018 to 2020 (reduced frequency). Vegetation in small subplots in annual frequency and reduced frequency plots was compared in August 2021 to test the effects of a short period without clipping on diversity and composition. To test the relative importance of recruitment and survival on diversity and composition, four 0.25 </span><span>×</span><span> 0.25 m quarter plots were established within each of 10 annual-frequency plots per site following a clipping treatment in fall 2019 and assigned a 2 </span><span>×</span><span> 2 factorial arrangement of transplantation of sods from long-unburned areas and herbicide application. Reducing the frequency of clipping reduced plant diversity and altered composition at both sites. A comparison of diversity and trait composition responses to transplant and herbicide treatments revealed how recruitment and survival combined to affect species diversity. Partial or complete recovery of diversity following clipping and litter removal at both sites was driven by rapid increases in short-lived, resilient species that show fire-stimulated emergence from a seed bank and the persistence of long-lived species capable of surviving the prolonged period without fire or clipping. Species with reduced resilience and persistence were more likely to be lost in the reduced frequency treatment. Results are consistent with a model of short-term coexistence of maximum species diversity maintained by the most frequent fire regimes fuels will permit.</span></p>
Data from: Nitrogen addition and warming modulate the pathogen impact on plant biomass by shifting intraspecific functional traits and reducing species richness
<p><span>1. </span><span>Foliar fungal pathogens can substantially reduce plant biomass. This effect can be modulated by environment conditions, such as soil nitrogen availability and air temperature. The ongoing global changes are altering these variables and thus interact with pathogens to influence plant biomass, but experimental test of their interactions is scarce. </span></p> <p><span>2. </span><span>We conducted a 4-year field experiment in a Tibetan alpine meadow to examine the interactive effects of nitrogen addition, warming and foliar pathogens (via fungicide application) on plant biomass. We also measured plant functional traits, species richness and abundance to test the possible mechanisms underlying these interactions. </span></p> <p><span>3. </span><span>Our results showed that foliar fungal pathogens reduced plant community biomass under nitrogen addition, which in turn weakened the positive nitrogen effect on community biomass. Mechanistically, nitrogen addition shifted the plant communities towards fast-growing traits; this happened predominantly because of changes in within-species trait values, including an increase in specific leaf area and height. These trait changes resulted in greater suppression of plant biomass by pathogens, likely because of the trade-offs associated with the allocation of resources to plant growth and defense. Moreover, the reduction in species richness amplified the pathogen effect under nitrogen addition due to the increased density and susceptibility of the most dominant species (i.e. Kobresia capillifolia). Furthermore, warming did not interact with pathogens and nitrogen addition to influence plant community biomass, but their three-way interaction modified the biomass of K. capillifolia. Specifically, warming enhanced the positive effect of nitrogen addition on the biomass of K. capillifolia in the fungicide, low infection plots, while it weakened the nitrogen effect in the no fungicide, high infection plots.</span></p> <p><span>4. </span><span>Synthesis:</span> <span>Our results demonstrate how pathogens interact with nitrogen addition and warming to influence the biomass of dominant species and the whole plant community. Our study highlights the importance of considering foliar fungal pathogens when assessing ecosystem responses to multiple global change factors.</span></p>
