Here we show that cell-laden hydrogels can be patterned with algorithmically generated dendritic vessel networks and other complex hierarchical networks by using sacrificial templates made from laser-sintered carbohydrate powders. We quantified and modulated gradients of cell proliferation and cell metabolism emerging as a result of fluid convection through these networks and of diffusion of oxygen and metabolites out of them. We also show scalable strategies for the fabrication, perfusion culture and volumetric analysis of large tissue-like constructs with complex and heterogeneous internal vascular architectures. Perfusable dendritic networks in cell-laden hydrogels may help sustain thick and densely cellularized engineered tissues, and assist interrogations of the interplay between mass transport and tissue function.</p>
Data from: Vascular epiphytes show low physiological resistance and high recovery capacity to episodic, short-term drought in Monteverde, Costa Rica
<ol> <li>Tropical montane cloud forests support abundant epiphytic vascular plant communities that serve important ecosystem functions, but their reliance on atmospheric inputs of water may make them susceptible to the drying effects of rising cloud bases and more frequent droughts.</li> <li>We conducted a common garden experiment to explore the combined effects of decreasing cloud influence—lower humidity, warmer temperature, brighter light—and meteorological drought (i.e., absence of rain) on the physiology and morphology of vascular epiphytes native to primary forests of Monteverde, Costa Rica. The epiphytes, which exhibited C<sub>3</sub> photosynthesis, were sourced from a lower montane cloud forest (CF) or a rainforest below the current cloud base (RF) and transplanted into nearby shadehouses (CF or RF shadehouse, respectively). Vapor pressure deficit (VPD) and light availability, measured as photosynthetically active radiation, were 2.5 and 3.1 times higher in the RF than the CF shadehouse. Half of the plants were subjected to a severe four-week drought followed by a recovery period, and the other half were watered controls.</li> <li>Plants subjected to low VPD/light conditions of the CF shadehouse were physiologically and morphologically resistant to the drought treatment. However, compared to control plants, both sources of plants subjected to high VPD/light conditions of the RF shadehouse experienced declines in maximum net photosynthesis (A<sub>max</sub>), stomatal conductance (g<sub>s</sub>), and the proportion of healthy leaves (those not exhibiting chlorosis, desiccation, or necrosis). At peak drought, leaves from the RF were 19% thinner than controls. Within 7-14 days after rewatering, A<sub>max</sub>, g<sub>s</sub>, and leaf health recovered to nearly the levels of controls. Growth rate, mortality, and phenology were unaffected by the treatments.</li> <li>The divergent responses to drought in the CF versus RF shadehouses, combined with the recovery in the RF shadehouse, indicate that these epiphytes possess adaptive properties that confer low resistance, but high recovery capacity, to episodes of short-term drought over a range of cloud influence. In addition, the reduction in A<sub>max</sub> suggests stomatal regulation that favors water conservation over carbon acquisition, a strategy that may inform epiphyte responses to rising clouds and increasing drought frequency expected in the long term.</li> </ol>
Vascular plant community data for Northwest Territories, Canada
<p><span><span>Climate change is altering disturbance regimes outside of historical norms, which can impact biodiversity by selecting for plants with particular traits. The relative impact of disturbance characteristics on plant traits and community structure may be mediated by environmental gradients. We aimed to understand how wildfire impacted understory plant communities and plant regeneration strategies along gradients of environmental conditions and wildfire characteristics in boreal forests. We established 207 plots (60m<sup>2</sup>) in recently burned stands and 133 plots in mature stands with no recent fire history in comparable gradients of stand type, site moisture (drainage), and soil organic layer (SOL) depth in two ecozones in Canada's Northwest Territories. <a name="_Hlk43198784">At each plot, we recorded all vascular plant taxa in the understory</a> and measured the regeneration strategy (seeder, resprouter, survivor) in burned plots, along with seedbed conditions (mineral soil and bryophyte cover). Dispersal, longevity, and growth form traits were determined for each taxon. Fire characteristics measured included proportion pre-fire SOL combusted (fire severity), date of burn (fire seasonality), and pre-fire stand age (time following fire). Results showed understory community composition was altered by fire. However, burned and mature stands had similar plant communities in wet sites with deep SOL. In the burned plots, regeneration strategies were determined by fire severity, drainage, and pre- and post-fire SOL depth. Resprouters were more common in wet sites with deeper SOL and lower fire severity, while seeders were associated with drier sites with thinner SOL and greater fire severity. This led to drier burned stands being compositionally different from their mature counterparts and seedbed conditions were important. Our study highlights the importance of environment-wildfire interactions in shaping plant regeneration strategies and patterns of understory plant community structure across landscapes, and the overriding importance of SOL depth and site drainage in mediating fire severity, plant regeneration, and community structure.</span></span></p> <p> </p>
Data from: Acute cytotoxicity and increased vascular endothelial growth factor after in vitro nitrogen mustard vapor exposure
<p>RATIONALE: Nitrogen mustard (NM) is a highly toxic alkylating agent. It is classified as chemical threat due to its potential use as a warfare agent. When inhaled, mustard exposure can cause both acute and chronic lung injury. The aims of this study are to develop an in vitro culture system for modeling mustard-induced airway injury and to identify growth factors contributing to airway pathology.</p> <p><br> METHODS: Primary human bronchial epithelial cells co-cultured with primary human pulmonary endothelial cells were exposed to NM (25, 50, 100, 250 or 500 µM) or PBS (control) for 1 hour. Lactate dehydrogenase (LDH) and trans-epithelial electrical resistance (TEER) were measured prior to and 24 hours after NM exposure. Endothelial cultures were then stained for live/dead staining. Exposed airway media was also analyzed for growth factors using Luminex multiplex technology. </p> <p><br> RESULTS: A one-hour NM vapor exposure increased supernatant LDH and decreased TEER at 24 hours for all cultures exposed to NM concentrations greater than or equal to 50 µM. Evidence of endothelial cell death occurred at NM concentrations of 250 and 500 µM. Vascular endothelial growth factor (VEGF) signaling, specifically VEGF-A and placental growth factor (PlGF), increased in NM-exposed co-culture media compared to PBS controls. </p> <p><br> CONCLUSIONS: NM vapor exposure causes significant airway epithelial and endothelial injury. Increased VEGF signaling occurred in airway co-cultures exposed to higher NM concentrations with concurrent endothelial cell death. Future studies are required to validate the role of VEGF signaling in both acute and chronic mustard-induced airway pathology. </p>
Multiple sequence alignment for the native Norwegian vascular plant phylogeny
<p>Methods: We produced a multi-locus Maximum Likelihood (ML) phylogeny using a combination of newly produced DNA sequences from herbarium specimens and sequences available from public repositories. We combined the phylogeny with species occurrence data to estimate phylogenetic diversity and phylogenetic endemism across Norway, using a spatial randomization to judge statistical significance. We used multiple-model inference to identify environmental variables that contributed the most to the patterns of phylogenetic diversity. Finally, we estimated phylogenetic turnover and used this to identify Norwegian plant assemblages in terms of composition and evolutionary history.<br> <br> Results: Our ML phylogeny contained 87% of all currently described native Norwegian vascular plants. Assemblages were phylogenetically overdispersed in warmer and wetter regions of Norway, as well as in regions with a longer post-glacial history. In cold and dry regions, plant assemblages were phylogenetically clustered, and characterised by neo-endemism, while the mild and wet regions were characterised by both paleo- and neo-endemism. Phylogenetic diversity was positively correlated with summer temperature and habitat heterogeneity, and peaked in the southeast of Norway.<br> <br> Main conclusions: Both contemporary ecological factors (climate and habitat heterogeneity), and post-glacial history seem to have shaped the phylogenetic structure of the flora of Norway. The flora in the far north of Norway appear to be a result of recent diversification while the coastal regions are assemblages of deeper lineages. Our results suggest that there is an evolutionary signal in the distribution of the Norwegian vascular flora.</p>
Influence of polymorphisms in the vascular endothelial growth factor gene on allograft rejection after kidney transplantation: a meta-analysis
<p><span><b><i>Purpose</i></b><i> </i>Reported associations of allograft rejection in kidney transplant patients with <i>VEGF</i> single nucleotide polymorphisms (SNPs) have been inconsistent between studies, which prompted a meta-analysis to obtain more precise estimates.</span></p> <p><span><b><i>Methods</i></b><i> </i>Using the PICO elements, kidney transplant patients (P) were compared by genotype data between rejectors (I) and non-rejectors (C) in order to determine the risk of allograft rejection (O) attributed to the <i>VEGF</i> SNPs. Literature search of four databases yielded seven articles. To calculate risks for allograft rejection, four SNPs were examined. Meta-analysis treatments included outlier and subgroup analyses, the latter was based on ethnicity (Indians/Caucasians) and rejection type (acute/chronic). Multiple comparisons were corrected with the Bonferroni test. </span></p> <p><span><span><b><i>Results</i></b> Five highly significant outcomes (P<sup>a</sup> < 0.01) survived Bonferroni correction, one of which showed reduced risk for the <i>var</i> allele (OR 0.61, 95% CI 0.45-0.82). The remaining four indicated increased risk for the <i>wt</i> allele where the chronic rejection (OR 2.10, 95% CI 1.36-3.24) and Indian (OR 1.44, 95% CI 1.13-1.84) subgroups were accorded susceptibility status. </span></span></p> <p><span><b><i>Conclusions</i></b> Risk associations for renal allograft rejection were increased and reduced on account of the <i>wt</i> and <i>var</i> alleles, respectively. These findings could render the <i>VEGF</i> polymorphisms useful in the clinical genetics of kidney transplantation. </span></p>
Raster and original working data for the paper Holocene matters: landscape history accounts for current species richness of vascular plants in forests and grasslands of eastern Central Europe
<p>Aim: Current species-richness patterns are sometimes interpreted as a legacy of landscape history, but historical processes shaping the distribution of species during the Holocene are frequently omitted in biodiversity models. Here, we test their importance in modelling current species richness of vascular plants in forest and grassland vegetation.<br> Location: Western Carpathians and adjacent regions.<br> Taxon: Vascular plants.<br> Methods: Numbers of all species and of habitat specialists were extracted from plot records of forest and grassland vegetation. For each plot, environmental and historical data were derived from thematic maps. Historical data related to the persistence of (i) temperate taxa during the Late Glacial and Early Holocene, (ii) open-landscape taxa during the Middle Holocene, and (iii) taiga species during the Late Holocene were based on 112 fossil pollen profiles. Boosted regression trees were used to model spatial patterns in species richness.<br> Results: Historical variables always appeared among the best predictors of current species richness. In light forests, species richness highly mirrored both the Late Glacial (12.5% contribution) and Middle-Holocene (8.6%) landscape history. The latter factor became an important predictor also for species richness of steppe grasslands (8.3%) along with temperature seasonality (11.9%). Species richness of dark coniferous forests was best predicted by the Late-Holocene occurrence of taiga forests (14.8%), which had an even stronger effect on the richness of habitat specialists (20.5%). <br> Main conclusions: Landscape changes since the Last Glacial Maximum are important predictors of current plant species richness. The historical effects were found to be habitat-specific and, because they may interact with recent environmental conditions and anthropogenic pressures, they often show a non-linear relationship with species richness. We provide one possible direction of incorporating past landscape changes into the models of species richness.</p>

Higher vascular plant abundance associated with decreased ecosystem respiration after 20 years of warming in the forest-tundra -ecotone
<p><span>The ongoing climate warming is promoting shrub abundance in high latitudes, but the effect of this phenomenon on ecosystem functioning is expected to depend on whether deciduous or evergreen species increase in response to warming. </span></p> <p><span>To explore effects of long-term warming on shrubs and further on ecosystem functioning, we analyzed vegetation and ecosystem CO<sub>2</sub> exchange after 20 years of warming in the forest-tundra ecotone in sub-arctic Sweden. A previous study conducted nine years earlier had found increased evergreen <em>Empetrum</em> <em>nigrum</em> ssp. <em>hermaphroditum</em> in the forest and increased deciduous <em>Betula</em> <em>nana</em> in the tundra. </span></p> <p><span>Following current understanding, we expected a continued increase in shrub abundance that would be stronger in tundra than in forest. We expected warming to increase ecosystem respiration (</span><span>R<sub>e</sub></span><span>) and gross primary productivity (GPP), with a greater increase in </span><span>R<sub>e </sub>in tundra due to increased deciduous shrub abundance, leading to a less negative net ecosystem exchange (NEE) and reduced ecosystem C sink strength. </span></p> <p><span>As predicted, vascular plant abundances were higher in the warmed plots with a stronger response in tundra than in forest. </span><span>However, whereas <em>B. nana</em> had increased in abundance since the last survey, <em>E. hermaphroditum </em>abundance had declined due to several moth and rodent outbreaks during the past decade. </span><span>I</span><span>n contrast to predictions, </span><span>R<sub>e </sub>was significantly lower in the warmed plots irrespective of habitat, and GPP increased marginally only in the forest. The lower R<sub>e</sub> and a higher GPP under warming in the forest together led to increased net C sink. </span><span>R<sub>e </sub>was negatively associated with the total vascular plant abundance.</span></p> <p><span>Our results highlight the importance of disturbance regimes for vegetation responses to warming. </span><span>Climate warming may promote species with </span><span>both a high capacity to grow under warmer conditions and a resilience towards herbivore outbreaks. Negative correlation between R<sub>e</sub> and total vascular plant abundance further indicates that t</span><span>he </span><span>indirect impacts of increased plants on soil microclimate may become increasingly important for ecosystem CO<sub>2</sub> exchange </span><span>in the long </span><span>run</span><span>, </span><span>which adds to the different mechanisms that link warming and CO<sub>2</sub> fluxes in northern ecosystems.</span></p>

Pattern and driver of the compositional variations in a tropical cloud forest: Comparing vascular epiphytes with terrestrial woody plants
<p>β-diversity patterns (the compositional variations across sites) and their drivers are the major concerns of biodiversity research and conservation practices, whereas such information remains scarce for vascular epiphytes, especially in tropical forest communities. This study aimed to reveal the pattern and driving process of the compositional variations of vascular epiphytes in a tropical cloud forest on Hainan island, southern China, and their differences from those of terrestrial woody plants. To this end, we quantified their between-habitat compositional variations and distinguished the underlying components of β-diversity (nestedness and turnover). We then examined the relative roles of niche-based and neutral processes in driving the compositional variations by using a null model approach. Our results showed that the between-habitat compositional variations were significant for both plant assemblages and stronger in vascular epiphytes than in terrestrial woody plants. The turnover component of β-diversity was significantly stronger in terrestrial woody plants, accounting for 73.16%–80.08% of the variations. By contrast, the nestedness component was significantly stronger in vascular epiphytes and characterized 46.82%–67.5% of the variations. Besides, the compositional variations of both plant assemblages, especially terrestrial woody plants, were generally poorly fitted by the simulated niche-based scenarios but well fitted by the simulated neutral scenarios. Overall, the compositional variations of both plant assemblages were significant and mainly due to dispersal limitation, albeit to varying degrees. Hence, further studies of these plant assemblages at local scales should not be ideologically limited to the niche-based framework. Moreover, the stronger nestedness observed in vascular epiphytes suggests the greater importance of prioritizing conservation efforts in the species-rich habitats for these plants.</p>

Leaf economics in a three‐dimensional environment: Testing leaf trait responses in vascular epiphytes to land use, climate, and tree zone
<p>1. The study of functional traits offers predictive power for community ecology. Particularly in cases where individual species are difficult to study, known properties of trait spectra, such as the leaf economics spectrum (LES), and trait-environment relationships can provide crucial generalizable information that can contribute to forecasts of distributional shifts in response to the abiotic effects of climate and land use changes.</p> <p>2. Vascular epiphytes have been proposed as indicators of environmental change, but we know little about the ecology of most species. Key functional trait assumptions are based on terrestrial plants; testing these in epiphytes verifies their universality and will inform applying functional traits in predicting epiphyte responses to climate and land use change.</p> <p>3. In this study, we use functional traits from 37 vascular epiphyte species from forests and shade coffee farms at two sites in northern Nicaragua. We compare correlations among traits and intraspecific trait variances with those of terrestrial plants and among epiphyte taxonomic groups. We also test trait responses to environmental differences between sites and land use types, and within zones of the tree.</p> <p>4. We find that epiphyte leaf traits fall toward the slower end of the LES, but with about one-third lower leaf nitrogen per change in specific leaf area (SLA) relative to terrestrial herbaceous plants. Bromeliads show less relationship between these traits than other epiphyte groups and also deviate in other trait interrelationships, suggesting unique leaf construction.</p> <p>5. Trait-environment relationships varied most strongly along vertical gradients within trees, but some traits, including SLA and carbon isotope ratio, also responded to land use and site differences.</p> <p>6. We present evidence that trait relationships established for terrestrial plants appear to translate to epiphytes, but identify some possible caveats. Strong trait response to vertical gradients within trees suggests that within-canopy shifts could provide resilience to climate and land use changes for some epiphyte species.</p>
