The functional role and diversity of soil nematodes are stronger at high elevation in the lesser Himalayan mountain ranges
<p>Soil nematodes are a foremost component of terrestrial biodiversity, they display the whole gamut of trophic guilds and life strategies, and by their activity, affect major ecosystem process, such as organic matter degradation and carbon cycling. Based on nematodes' functional types, nematode community indices have been developed, and can be used to link variation in nematodes community composition and ecosystem processes. Yet, the use of these indices has been mainly restricted to anthropogenic stresses. In this study, we propose to expand the use of nematodes' derived ecological indices in order to link soil and climate properties with soil food webs, and ecosystem processes that all vary along steep elevation gradients. For this purpose, we explored how elevation affects the trophic and functional diversity of nematode communities sampled every 300 m, from about 1000 m to 3700 m above sea level, across four transects in the lesser Himalayan range of Jammu and Kashmir. We found that (1) the trophic and functional diversity of nematodes increases with elevation; (2) differences in nematodes communities generate habitat-specific functional diversity; (3) the maturity index (MI), increases with elevation, while the enrichment index decreases, indicating less mature and less productive ecosystems, enhanced fungal-based energy flow, and a predominant role of nematodes in generating carbon influxes at high elevation sites. We thus confirm that the functional contribution of soil nematodes to belowground ecosystem processes, including carbon and energy flow, is stronger at high elevation. Overall, this study highlights the central importance of nematodes in sustaining soil ecosystems and brings insights into their functional role, particularly in alpine and arctic soils.</p>
Elevated CO2 alleviates adverse effects of drought on plant water relations and photosynthesis: a global meta-analysis
<p><span>1. </span><span>The elevated CO2 concentration (eCO2) is expected to improve plant water relations and carbon (C) uptakes, with a potential to mitigate drought stress. However, the interactive effects of eCO2 and drought on plant physiology and growth are not clear. </span></p> <p><span>2. </span><span>We performed a meta-analysis on the interactive effects of eCO2 and drought on plant water relations, photosynthesis, biomass production and allocation. </span></p> <p><span>3. </span><span>We found that eCO2 did not lead to conservation of soil water, but improved leaf water status under drought conditions as evidenced by a higher leaf relative water content and a less negative midday leaf water potential, resulting from reduced stomatal conductance (gs) and increased root to shoot ratio. Elevated CO2 retarded gs response to drought, which may be mediated by decreases in leaf abscisic acid concentration under eCO2 and drought. Drought imposed stomatal limitations on photosynthesis (A), which was alleviated by eCO2 via increasing intercellular CO2 concentration (Ci). This led to a stronger A response to eCO2 under drought, supporting the "low Ci effect". However, no interaction of eCO2 and drought was detected on plant biomass production. Intrinsic water use efficiency (iWUE) increased proportionally with eCO2, while plant-scale WUE was less responsive to eCO2 regardless of water availability. The advantages of eCO2 on C3 plants over C4 plants under well-watered conditions diminished under drought conditions. Within C3 plants, drought caused a greater reduction in biomass for woody plants than for herbs. Biomass declined progressively as drought prolonged for plants growing in both ambient CO2 and eCO2. The physiology and biomass of plants growing in pots showed more negative responses to drought than those growing in field. Biomass increase in free-air carbon dioxide enrichment experiments was significantly less than those in growth chamber and open top chamber experiments. </span></p> <p><span>4. </span><span>Synthesis</span><span>. These findings suggest that eCO2 can alleviate the adverse impacts of drought on plant water relations and C sequestration, and are of significance in the prediction of plant growth and ecosystem productivity under global changes.</span></p>
Diurnal pastoralism does not reduce juvenile recruitment nor elevate allostatic load in spotted hyenas
<p>1. Anthropogenic activity can have substantial effects on wildlife. These effects may vary according to the characteristics of the activity and the species involved. While effects on behavior are well-studied, studies of effects on fitness and physiology are scarce, particularly for group-living species.</p> <p>2. We exploited a natural experimental setup to investigate the effect of diurnal pastoralism on juvenile recruitment and allostatic load in a population of free-ranging spotted hyenas in the Ngorongoro Crater, Tanzania, over a 24-year period.</p> <p>3. Pastoralism was restricted to the territories of two of the eight study clans, allowing us to compare juvenile recruitment in exposed and unexposed clans. We also compared fecal glucocorticoid metabolite concentrations (fGMC) – a biomarker of an organism's allostatic load – between exposed and unexposed clans using 975 fecal samples from 475 hyenas.</p> <p>4. We found no detectable difference in juvenile recruitment nor fGMC between the exposed and unexposed clans, indicating that the pastoralism had no substantial deleterious effect on the spotted hyenas. The lack of a deleterious effect likely stems from the combined effect of the predictable and undisruptive nature of the pastoralism, the socio-ecology of spotted hyenas, and the Ngorongoro Crater's consistently abundant prey.</p> <p>5. Our findings demonstrate that exposure to anthropogenic activity may be compatible with the persistence of certain group-living species, especially if the overlap between the species' critical behaviors and the activity is limited. Our study thereby provides new perspectives for ecologists, conservation biologists, and stakeholders who seek to assess human-wildlife conflicts and balance the needs of local human communities and wildlife.</p>

Fig. 4 in Divergence in Body Mass, Wing Loading, and Population Structure Reveals Species-Specific and Potentially Adaptive Trait Variation Across Elevations in Montane
Fig. 4. Parameter estimates for fixed effects (β) in spatial mixed effects models (spaMM) for each species, with 95% CIs, testing the effects of Elevation (scaled), AMT (scaled), and Elevation * AMT interaction on traits; Asterisk indicates the CIs did not encompass zero. If no estimate is shown that variable was not included in the model for that species. Maps show spatial trends of trait value from interpolation of estimates for each model (filled.mapMM function in spaMM). Note, for B. vosnesenskii mass and pw-Empty, the low-AIC models were intercept plus random effect only, but for visualization, results are presented for the next best model with at least one fixed effect (seeTable 2 for model details).
Fig. 3 in Divergence in Body Mass, Wing Loading, and Population Structure Reveals Species-Specific and Potentially Adaptive Trait Variation Across Elevations in Montane
Fig. 3. Effect predictions (with 95% CI) of mass (field and empty), thorax size (ITS), forewing area, and transformed wing loading (pw-Field, pw-Empty) against (A) latitude, (B) AMT (Worldclim BIO1 variable), and (C) elevation from univariate linear mixed effects models for B. vancouverensis (blue) and B. vosnesenskii (red). Statistical analyses were conducted on log-transformed mass, ITS, and wing loading (see SuppTable S4 [online only]), but responses were back-transformed to the original scale for plotting (plot_model function in sjPlot). Lines are labeled with significance estimate of the β parameter estimated from lmerTest (*P <0.05; ***P <0.001; unlabeled = not significant, CI encompasses zero).

Fig. 2. Boxplots (shown for site means) and tests of differences between species in overall field mass (A), empty mass (B), ITS (C), forewing area (D), pw-Field (E), and pw-Empty (F). Statistical tests are summaries taken from linear mixed models (full report and parameter estimates in Supp Table S1 [online only]), showing marginal (R 2) and conditional (R 2) R2 values and with df for the species effect t statistic and P-values (***P <0.001; N.S. = not significant) associated with the M C relevant fixed effect estimated using lmertest. Mass, ITS, and pw values were log-transformed for statistical tests but plotted untransformed. Panels G–L show scatterplots of correlations among several traits for each bee and are presented with Pearson's correlation coefficients (r) and 95% CIs (see SuppTables 2 and 3 [online only] and Supp Figs. S2–S4 [online only] for additional trait correlation statistical details).
