abstract = {A key limitation for dryland restoration is the availability of native seed sources adapted to arid conditions and however, many native forbs lack basic ecological data relevant to restoration seed production. To address this gap, we evaluated six native forb species collected across the Colorado Plateau for their potential to be developed into restoration materials. We established a common garden trial designed to replicate agricultural conditions using 100 individuals from four populations per species and measured survival, growth, reproduction, and pollinator visitation. Three species, Spreading fleabane ( Erigeron divergens ), Hoary aster ( Dieteria canescens ), and Hairy false goldenaster ( Heterotheca villosa ), exhibited high survival, prolific flower and seed production, and attracted diverse pollinator groups, including multiple native bee taxa. In contrast, Horsetail milkweed ( Asclepias subverticillata ) and Prairie flax ( Linum lewisii ) had low seed yields but attracted distinct floral visitor guilds. Sphaeralcea parvifolia exhibited poor propagation success. Despite variable performance among species and populations, the trial demonstrated that plantings comprising multiple species and populations supported a wide array of pollinators and extended the timing of floral resource availability. These results underscore the value of integrating functionally complementary species into restoration plantings to promote pollinator diversity and identify candidate species for native seed production.},

abstract = {Abstract Photosystem II (PSII) is among the most thermally sensitive components of photosynthesis, and emerging evidence suggests that plants in diverse biomes face an increasing risk of PSII damage under future climate change. However, uncertainties in the distribution and drivers of PSII thermal tolerance (T crit ) limit our ability to predict thermal risk in plant communities across spatial scales. Here, we evaluate whether intraspecific variation in T crit corresponds to leaf reflectance spectra (400–2,500 nm) to identify mechanisms associated with T crit in field conditions and assess the potential of its estimation using remote sensing platforms. We measured T crit using temperature response curves of minimal fluorescence ( F o ) along with corresponding leaf reflectance spectra in two foundation tree species: Populus fremontii (US Southwest) and Metrosideros polymorpha (Hawai'i). P. fremontii was sampled under both moderate (<40°C) and extreme (>45°C) heat. Consistent spectral signatures of T crit emerged across species and sampling conditions, with the strongest signatures in P. fremontii under extreme heat. In P. fremontii, spectra captured up to roughly half of T crit variation and allowed T crit estimation ( R 2 = 0.24–0.30 and RMSE < 1.0°C) and classification of high‐versus low‐T crit (71%–77% accuracy). Across both species, T crit tended to increase with spectral indices reflecting higher chlorophyll content and lower carotenoids, nonphotochemical quenching, and leaf water content. These findings suggest that variation in PSII thermal tolerance is linked to fundamental biochemical properties of leaves, which are reflected in their optical traits. As climate extremes intensify, spectral screening and scaling of T crit via remote sensing may support improved conservation, management, and risk assessment in vulnerable ecosystems. , Plain Language Summary Plant communities are critical for the Earth system, but many face increasing pressures in a changing climate. One key risk is that plants may reach temperatures that damage their photosynthetic machinery. However, thermal tolerance varies widely between species and individuals, making it difficult to assess plant vulnerability at a scale. Here we test whether thermal tolerance can be predicted from how leaves reflect light at different wavelengths—a method known as leaf spectroscopy that captures key leaf traits and can be scaled using remote sensing platforms. We tested this approach in two distinct tree species: Populus fremontii from the U.S. Southwest and Metrosideros polymorpha from Hawai'i. Despite their differences, both showed similar spectral patterns linked to the temperature at which photosynthesis begins to break down. These signatures suggested that plants with higher thermal tolerance tend to have more chlorophyll and less leaf water and protective pigments than plants with lower tolerance. In P. fremontii, leaf spectra explained up to approximately half of the variation in thermal tolerance and predicted high versus low tolerance with 70%–80% accuracy. These results help understand the mechanisms associated with thermal tolerance in the field, and may support landscape‐scale assessments of plant vulnerability to heat using remote sensing. , Key Points Leaf reflectance spectra (400–2,500 nm) show consistent signatures of PSII thermal tolerance (T crit ) in contrasting species and conditions In Populus fremontii , spectra predicted T crit (R 2 = 0.24–0.3 and RMSE < 1°C) and classified high versus low T crit with 71%–77% accuracy Spectral indices suggest T crit is positively correlated with chlorophyll content and negatively correlated with water and carotenoid content},

abstract = {Importance Patients with cancer experience significantly higher rates of suicidal self-directed violence (SSDV; defined as both fatal and nonfatal suicide attempts) than the general population. Objective To assess longitudinal risks and methods for SSDV among veterans and identify associated risk factors to improve screening and prevention strategies. Design, Setting, and Participants This national cohort study of veterans with cancer was conducted between January 2014 and December 2023. Data from established oncology and suicide registries and the Veterans Health Administration (VA) were used. Data were analyzed from January 2025 to February 2026. Exposure Diagnosis of invasive solid or hematologic cancer. Main Outcomes and Measures The primary outcome was SSDV and rates per 100 000 person-years. Risk factors for SSDV were estimated as adjusted hazard ratios (aHRs) from multivariable Cox proportional hazards models. Results Among 292 271 veterans (mean [SD] age, 69.0 [9.4] years; 7108 female [2%]; 2664 American Indian or Alaska Native [1%]; 1365 Asian [1%]; 62 538 Black or African American [21%]; 13 965 Hispanic or Latino [5%]; 2306 Native Hawaiian or Other Pacific Islander [1%]; 219 205 White [75%]), there were 2400 SSDV events (1%; overall rate, 203 [95% CI, 195-211] per 100 000 person-years). The most common method used was poisoning (eg, opioids; 617 attempts [26%]). Estimated SSDV probabilities were highest for those with central nervous system (CNS), pancreas, head and neck, liver and biliary system, and thyroid cancer types. Veterans with severe frailty (544 [95% CI, 457-648] events per 100 000 person-years), advanced cancer (261 [95% CI, 233-293] events per 100 000 person-years), chronic mental illness (419 [95% CI, 399-439] events per 100 000 person-years), and high pain scores (236 [95% CI, 192-210] events per 100 000 person-years) had high SSDV rates compared with the overall cohort. Younger age (≤45 years; 643 [95% CI, 547-756] events per 100 000 person-years), female sex (369 [95% CI, 306-445] events per 100 000 person-years), American Indian or Alaska Native race (286 [95% CI, 201-407] events per 100 000 person-years), and CNS (394 [95% CI, 311-500] events per 100 000 person-years) and thyroid (359 [95% CI, 290-445] events per 100 000 person-years) cancers had high rates of nonfatal attempts. Increased SSDV hazards (6 months postdiagnosis) occurred among veterans of Asian compared with White race (aHR, 2.55; 95% CI, 1.12-5.76), unmarried veterans (aHR, 1.83; 95% CI, 1.47-2.27), veterans with CNS (aHR, 2.07; 95% CI, 1.13-3.80) or head and neck (aHR, 1.67; 95% CI, 1.13-2.48) compared with lung cancer, and veterans with advanced cancer (aHR, 1.30; 95% CI, 1.00-1.68). Risk for most veterans decreased over time after diagnosis; however, risk remained elevated 5 years postdiagnosis for younger veterans (aged ≤45 vs 46-64 years; aHR, 1.58; 95% CI, 1.29-1.94), unmarried veterans (aHR, 1.48; 95% CI, 1.35-1.62), veterans with CNS vs lung cancer (aHR, 1.63; 95% CI, 1.22-1.27), and veterans with advanced cancer (aHR, 1.30; 95% CI, 1.14-1.50). Conclusions and Relevance This study found that veterans with cancer were at risk for SSDV that persisted years into survivorship. Previously overlooked high risk, subgroups, such as younger veterans, Asian veterans, or veterans with thyroid cancer, stress the need to systematically track all suicidal behaviors, not just fatal attempts, to inform tailored screening and prevention strategies as a key component of cancer care.},

abstract = {Dryland managers face a dilemma balancing prescribed fire use with rare species conservation. In semi-arid grasslands and woodlands, managers often avoid burning habitats with threatened plants, though fire may reduce competition from invasive grasses and support native persistence. In the Madrean Sky Islands of southeastern Arizona, drought, altered fire regimes, and non-native species encroachment are transforming lower elevation grasslands and woodlands, home to the endangered forb, Pectis imberbis. These stressors interact in complex ways, yet cumulative effects on rare species like P. imberbis remain poorly understood. We conducted a fully factorial greenhouse experiment to test how fire, drought, and competition affect P. imberbis. Plants were grown from seed with intra- and interspecific competitors, then exposed to fire and drought. After 39 weeks, we measured above- and belowground biomass. Interspecific competition and drought reduced biomass, but burning appeared to ameliorate interspecific competition's negative effects. Pectis imberbis resprouted robustly after fire—even under drought and competition—though drought and intraspecific competition delayed resprouting. Our findings indicate prescribed fire may provide a safe and effective way to manage P. imberbis habitat while supporting broader goals such as invasive species control.},

abstract = {Globally, vegetation biodiversity is expected to decline as the rate of plant adaptation struggles to keep pace with rising temperatures. To support conservation efforts through remote sensing, we disentangled the nested effects of genetic and environmental influences on reflectance spectra, leveraging spectroscopy to assess plant adaptations to temperature. Specifically, we quantified the relative effect of plasticity and heritability on Populus fremontii (Fremont cottonwood) leaf reflectance using clonal replicates propagated from 16 populations and grown across three common gardens spanning a mean annual temperature gradient representing the thermal range of P. fremontii. We used variance partitioning to decompose phenotypic variation expressed in the leaf spectra into genotypic and environmental components to estimate broad-sense heritability. Heritability was strongly expressed in the spectral red edge (~ 680–750 nm) and shortwave infrared (~ 1400–3000 nm), though the heritability peak in the red edge was sensitive to extreme temperatures. By comparing distances of group centroids in principal component space, we determined that P. fremontii intraspecific spectral variation was shaped by the interaction between common garden site conditions and source population. Support vector machine models indicated pronounced environmental influence on spectral variation, as P. fremontii source population and garden location were classified at 71.8% and 92.6% accuracy, respectively. These findings emphasize the utility of reflectance data in separating genetic and environmental influences on plant phenotypes, offering a pathway to scale these insights across broader landscapes and aid in the conservation and management of vulnerable ecosystems in a warming climate.},

abstract = {Abstract Traditional harvest entails humans extracting and managing resources from intact, semi‐natural ecosystems. As such, it is inherently comprised of close interactions between humans and ecosystems and may provide unique insight into socio‐ecological systems. Traditional harvest is generally accompanied by traditional resource management and directly influences ecological community dynamics, species reproduction and distribution, and competitive interactions. Meanwhile, ecological processes, seasonality, and natural disturbances influence human behaviors, decision making, activities, and well‐being. As a result of this tight coupling, traditional harvest systems have the potential to serve as important laboratories for the study of ecological community dynamics. Resilience science, in particular, may benefit from greater appreciation of traditional harvest, wherein thresholds and bidirectional feedbacks may be more easily detected and modeled than in more diffuse socio‐ecological systems. Additionally, because traditional harvest links to cultural heritage and traditional ecological knowledge, a greater understanding of these systems may facilitate efforts to support marginalized communities and social equity. We here discuss the value of traditional harvest research for science and society, highlighting as a case study the traditional harvest of Emory oak acorns by Western Apache Tribal Nations. We argue that traditional harvest systems carry important heuristic value but are often assumed to be rare or declining and are therefore relatively neglected by researchers, yet their persistence in modern agriculture‐dominated systems exemplifies resilience. As environmental change persists and natural systems near critical tipping points, understanding the role of humans in ecosystem resilience will be necessary to develop effective and sustainable management.},

abstract = {Understanding how vegetation responds to drought is fundamental for understanding the broader implications of climate change on foundation tree species that support high biodiversity. Leveraging remote sensing technology provides a unique vantage point to explore these responses across and within species. We investigated interspecific drought responses of two Populus species (P. fremontii, P. angustifolia) and their naturally occurring hybrids using leaf‐level visible through shortwave infrared (VSWIR and 400–2500 nm) reflectance. As F1 hybrids backcross with either species, resulting in a range of backcross genotypes, we heretofore refer to the two species and their hybrids collectively as ‘cross types’. We additionally explored intraspecific variation in P. fremontii drought response at the leaf and canopy levels using reflectance data and thermal unmanned aerial vehicle (UAV) imagery. We employed several analyses to assess genotype‐by‐environment (G × E) interactions concerning drought, including principal component analysis, support vector machine and spectral similarity index. Five key findings emerged: (1) Spectra of all three cross types shifted significantly in response to drought. The magnitude of these reaction norms can be ranked from hybrids>P. fremontii>P. angustifolia, suggesting differential variation in response to drought and (2) Spectral space among cross types constricted under drought, indicating spectral—and phenotypic—convergence and (3) Experimentally, populations of P. fremontii from cool regions had different responses to drought than populations from warm regions, with source population mean annual temperature driving the magnitude and direction of change in VSWIR reflectance. (4) UAV thermal imagery revealed that watered, warm‐adapted populations maintained lower leaf temperatures and retained more leaves than cool‐adapted populations, but differences in leaf retention decreased when droughted. (5) These findings are consistent with patterns of local adaptation to drought and temperature stress, demonstrating the ability of leaf spectra to detect ecological and evolutionary responses to drought as a function of adaptation to different environments. Synthesis. Leaf‐level spectroscopy and canopy‐level UAV thermal data captured inter‐ and intraspecific responses to water stress in cottonwoods, which are widely distributed in arid environments. This study demonstrates the potential of remote sensing to monitor and predict the impacts of drought on scales varying from leaves to landscapes.},

We investigated how variation in environmental conditions affects Gila Monsters' (Heloderma suspectum) space use by analyzing variability in annual home ranges from 12 populations. Using very-high-frequency telemetry data, annual home-range estimates were calculated for each lizard using weighted autocorrelated kernel density estimation (wAKDE) and minimum convex polygon (MCP) methods. Publicly sourced environmental data were used to calculate annual estimates for 10 biologically important variables related to temperature, precipitation, productivity, and terrain ruggedness. Model selection analysis was used to identify top candidate models, and model averaging was performed to identify the variables most strongly associated with home-range size. We found a strong positive relationship between wAKDE home-range size and both winter precipitation and active-season temperature. MCP home-range size was negatively correlated with time-lagged summer precipitation and positively correlated with winter precipitation. Gila Monsters may exhibit behavioral adaptations to maximize annual resource intake during periods of resource abundance and decrease space use during resource scarcity to minimize energetic demands.},

abstract = {ABSTRACT Plants respond to rapid environmental change in ways that depend on both their genetic identity and their phenotypic plasticity, impacting their survival as well as associated ecosystems. However, genetic and environmental effects on phenotype are difficult to quantify across large spatial scales and through time. Leaf hyperspectral reflectance offers a potentially robust approach to map these effects from local to landscape levels. Using a handheld field spectrometer, we analyzed leaf‐level hyperspectral reflectance of the foundation tree species Populus fremontii in wild populations and in three 6‐year‐old experimental common gardens spanning a steep climatic gradient. First, we show that genetic variation among populations and among clonal genotypes is detectable with leaf spectra, using both multivariate and univariate approaches. Spectra predicted population identity with 100% accuracy among trees in the wild, 87%–98% accuracy within a common garden, and 86% accuracy across different environments. Multiple spectral indices of plant health had significant heritability, with genotype accounting for 10%–23% of spectral variation within populations and 14%–48% of the variation across all populations. Second, we found gene by environment interactions leading to population‐specific shifts in the spectral phenotype across common garden environments. Spectral indices indicate that genetically divergent populations made unique adjustments to their chlorophyll and water content in response to the same environmental stresses, so that detecting genetic identity is critical to predicting tree response to change. Third, spectral indicators of greenness and photosynthetic efficiency decreased when populations were transferred to growing environments with higher mean annual maximum temperatures relative to home conditions. This result suggests altered physiological strategies further from the conditions to which plants are locally adapted. Transfers to cooler environments had fewer negative effects, demonstrating that plant spectra show directionality in plant performance adjustments. Thus, leaf reflectance data can detect both local adaptation and plastic shifts in plant physiology, informing strategic restoration and conservation decisions by enabling high resolution tracking of genetic and phenotypic changes in response to climate change. , Summary statement By growing the same locally adapted populations in reciprocal common gardens, we found that leaf reflectance can detect both genetic identity and phenotypic plasticity in Fremont cottonwood, an important riparian foundation species.},

abstract = {Abstract Climate change and river regulation alter environmental controls on riparian plant occurrence and cover worldwide. Simultaneous changes to river flow and air temperature could result in unanticipated plant responses to novel environmental conditions. Increasing temperature could alter riparian plant response to hydrology and other factors, while river regulation may exacerbate environmental stress through novel flows like those resulting from power generation. Further, plant establishment and growth may require differing conditions, which may be decoupled by novel conditions. Using a large dataset that spans a natural 5°C mean annual temperature (MAT) gradient and a Bayesian model that integrates plant occurrence and cover, we address four questions: (1) Does hotter MAT modify plant response to hydrology, substrate composition, topography, and cover of co‐occurring plant species? (2) Does the timing of hydropower tides benefit some species over others? (3) Does dam‐induced erosion hinder riparian species more than upland species? (4) Do occurrence and cover respond to different environmental variables, allowing for decoupling of life history processes? We addressed these questions with data collected along 364 km of the Colorado River downstream of Glen Canyon Dam, Arizona, United States of America. Occurrence and cover class were recorded in >10,000 plots from 2016 to 2020, along with environmental covariates that repeat across the climate gradient. For 36 species, plant occurrence and cover were modeled with respect to MAT, hydrology, substrate, topography, other plant cover, and their interactions with MAT. There were four key results. (1) Increasing MAT will not only directly influence plants but will mediate their responses to the environment, including greater dependence on stable water supplies. (2) The timing of hydropower tides shapes plant community composition. (3) Dam‐related erosion has an outsized effect on riparian species, which could lead to a loss of regionally unique plant species. (4) For all species, the most important covariates driving occurrence differed from those for cover, suggesting the potential for these life stages to be decoupled. Not only will climate change and river regulation independently alter plant distributions, interactions among hotter temperature, dam‐controlled flow patterns, and limited fine sediments will determine which species flourish or perish under future conditions.},

abstract = {Determining whether organisms can undergo adaptive evolution at a pace commensurate with contemporary climate change is critical to understanding and predicting the consequences of such change. Hybrid introgression is a mechanism of rapid evolution by which species may adapt to climatic shifts. Here, we examine variation in growth and survival in a long-term common garden experiment with a foundation tree species to determine if introgression is enhancing climate change resilience. Two naturally hybridizing tree species, low elevation Populus fremontii and high elevation Populus angustifolia, and hybrid and backcross genotypes were planted in a low elevation, warm common garden. We show that P. angustifolia and backcross trees are vulnerable to warming, and their survival is related to climate and transfer distance (proxies for climate change). Increased odds of survival are associated with genetic introgression, as indicated by RFLP genetic markers. Thus, for these long-lived foundation trees, hybrid introgression is associated with increased resistance to selection pressures in warmer, drier climates. These data highlight the importance of evolutionary patterns and processes in shaping ecosystem responses to climate change. If adaptive introgression through hybrid zones is common, hybrid-specific conservation policies and restoration should be reconsidered in the context of global change.},

We designed an experimental restoration garden in an arid system to investigate the relationship between seed source population and plant‐pollinator interactions. Seedlings planted in the garden were sourced from eight populations of each of seven forb species. For 18 months, we tracked flower visitation by insects. We used network analysis to examine the roles of plant species and populations. In the whole‐garden network, taller plants as well as those that differed more in temperature of the source environment from the garden were more generalized, receiving visitation from a higher subset of the local visitor community. We detected no other relevant network patterns consistent across the full garden. However, when within‐species networks were constructed, plants from different populations exhibited significant differences in metrics of centrality and generalization for four out of seven plant species. Plants sourced from populations that exhibit similar climatic conditions to those found in the experimental garden, as well as plants from populations that displayed traits indicative of greater pollinator reward (e.g., greater plant size and greater floral abundance), were linked to increased centrality and generalization in networks. Our results suggest that it may be possible to select restoration plantings by seed source to bolster the diversity and frequency of pollinator interactions in a site, and further, that considering how plant local adaptation serves pollinators is likely to be important in restoration success.},

abstract = {Abstract Understanding how vegetation responds to drought is fundamental for understanding the broader implications of climate change on foundation tree species that support high biodiversity. Leveraging remote sensing technology provides a unique vantage point to explore these responses across and within species. We investigated interspecific drought responses of two Populus species ( P . fremontii , P . angustifolia ) and their naturally occurring hybrids using leaf‐level visible through shortwave infrared (VSWIR and 400–2500 nm) reflectance. As F 1 hybrids backcross with either species, resulting in a range of backcross genotypes, we heretofore refer to the two species and their hybrids collectively as ‘cross types’. We additionally explored intraspecific variation in P. fremontii drought response at the leaf and canopy levels using reflectance data and thermal unmanned aerial vehicle (UAV) imagery. We employed several analyses to assess genotype‐by‐environment (G × E) interactions concerning drought, including principal component analysis, support vector machine and spectral similarity index. Five key findings emerged: (1) Spectra of all three cross types shifted significantly in response to drought. The magnitude of these reaction norms can be ranked from hybrids> P. fremontii > P. angustifolia , suggesting differential variation in response to drought and (2) Spectral space among cross types constricted under drought, indicating spectral—and phenotypic—convergence and (3) Experimentally, populations of P. fremontii from cool regions had different responses to drought than populations from warm regions, with source population mean annual temperature driving the magnitude and direction of change in VSWIR reflectance. (4) UAV thermal imagery revealed that watered, warm‐adapted populations maintained lower leaf temperatures and retained more leaves than cool‐adapted populations, but differences in leaf retention decreased when droughted. (5) These findings are consistent with patterns of local adaptation to drought and temperature stress, demonstrating the ability of leaf spectra to detect ecological and evolutionary responses to drought as a function of adaptation to different environments. Synthesis. Leaf‐level spectroscopy and canopy‐level UAV thermal data captured inter‐ and intraspecific responses to water stress in cottonwoods, which are widely distributed in arid environments. This study demonstrates the potential of remote sensing to monitor and predict the impacts of drought on scales varying from leaves to landscapes.},
