Bridging the flux gap: sap flow measurements reveal species-specific patterns of water-use in a tallgrass prairie
<p>Predicting the hydrological consequences following changes in grassland vegetation type (i.e., woody encroachment) requires an understanding of water flux dynamics at high spatiotemporal resolution for predominant species within grassland communities. However, grassland fluxes are typically measured at the leaf or landscape scale, which inhibits our ability to predict how individual species contribute to changing ecosystem fluxes. We used external heat balance sap flow sensors and a hierarchical Bayesian state-space modeling approach to bridge this "flux-gap" and estimate continuous species-level water flux in common tallgrass prairie species. Specifically, we asked: 1) How do diurnal and nocturnal water fluxes differ among woody and herbaceous plants? (2) How sensitive are woody and herbaceous species to environmental drivers of diurnal and nocturnal water flux? We highlight three results: (1) <i>Cornus drummondii</i>, the primary woody encroacher in this grassland, exhibited the greatest canopy-level water loss, (2) nocturnal transpiration was a large component of the water lost in this ecosystem and was driven primarily by C<sub>4</sub> grasses and <i>C. drummondii</i>, and (3) the sensitivity of canopy transpiration to environmental drivers varies among plant functional types and throughout a 24-hour period. Our data reveal important insights regarding the water-use strategies of woody versus herbaceous species in tallgrass prairies, and about the potential hydrological consequences of ongoing woody encroachment. We suggest that the high, static flux rates observed in woody species will likely deplete deep water stores over time, potentially creating hydrological deficits in grasslands experiencing woody encroachment and concomitantly increasing the vulnerability of these ecosystems to drought.</p>
Data from: Hunting behavior and feeding ecology of Mojave Rattlesnakes (Crotalus scutulatus), Prairie Rattlesnakes (C. viridis), and their hybrids in southwestern New Mexico
<p>Predators must contend with numerous challenges to successfully find and subjugate prey. Complex traits related to hunting are partially controlled by a large number of co-evolved genes which may be disrupted in hybrids. Accordingly, research on the feeding ecology of animals in hybrid zones has shown that hybrids sometimes exhibit transgressive or novel behaviors, yet for many taxa empirical studies of predation and diet across hybrid zones is lacking. We undertook the first such field study for a hybrid zone between two snake species, the Mojave Rattlesnake (<em>Crotalus scutulatus</em>) and Prairie Rattlesnake (<em>C. viridis</em>). Specifically, we leveraged established field methods to quantify hunting behaviors of animals, their prey communities, and diet of individuals across the hybrid zone in southwestern New Mexico, USA. We found that, even though hybrids had significantly lower body condition indices than snakes from either parental lineage, hybrids were generally similar to non-hybrids in hunting behavior, prey encounter rates, and predatory attack and success. We also found that, compared to <em>C. scutulatus</em>, <em>C. viridis</em> was significantly more active while hunting at night and abandoned ambush sites earlier in the morning, and hybrids tended to be more <em>viridis</em>-like in this respect. Prey availability was similar across the study sites, including within the hybrid zone, with Kangaroo Rats (<em>Dipodomys</em> spp.) as the most common small mammal both in habitat surveys and frequency of encounters with hunting rattlesnakes. Analysis of prey remains in stomachs and feces also showed broad similarity in diets, with all snakes preying primarily on small mammals and secondarily on lizards. Taken together, our results suggest that the significantly lower body condition of hybrids does not appear to be driven by differences in their hunting behavior or diet, and may instead relate to metabolic efficiency or other physiological traits we have not yet identified.</p>

Data from: Heterogeneity promotes resilience in restored prairie: implications for the 'environmental heterogeneity hypothesis'
<p>Enhancing resilience in formerly degraded ecosystems is an important goal of restoration ecology. However, evidence for the recovery of resilience and its underlying mechanisms requires long-term experiments and comparison to reference ecosystems. We used data from an experimental prairie restoration that featured long-term soil heterogeneity manipulations and data from comparable remnant (reference) prairie to (1) quantify the recovery of ecosystem functioning (i.e., productivity) relative to remnant prairie, (2) compare resilience of restored and remnant prairies to a natural drought, and (3) test whether soil heterogeneity enhances resilience of restored prairie. We compared sensitivity and legacy effects between prairie types (remnant and restored) and among four prairie sites that included two remnant prairie sites and prairie restored under homogeneous and heterogeneous soil conditions. We measured sensitivity and resilience as the proportional change in aboveground net primary productivity (ANPP) during and following drought (sensitivity and legacy effects, respectively) relative to average ANPP based on four pre-drought years (2014-2017). In non-drought years, total ANPP was similar between remnant and restored prairie, but remnant prairie had higher grass productivity and lower forb productivity compared to restored prairie. These ANPP patterns generally persisted during drought. Sensitivity of total ANPP to drought was similar between restored and remnant prairie, but grasses in restored prairie were more sensitive to drought. Post-drought legacy effects were more positive in restored prairie, and we attributed this to the more positive and less variable legacy response of forb ANPP in restored prairie, especially in the heterogeneous soil treatment. Our results suggest that productivity recovers in restored prairie and exhibits similar sensitivity to drought as remnant prairie. Furthermore, imparting heterogeneity promotes forb productivity and enhances prairie resilience to drought.</p>
Cycling temperature treatments and digestion in prairie lizards (Sceloporus consobrinus)
<p>In nature, many organisms experience a daily range of body temperatures. Thermal performance at stable temperatures is often extrapolated to predict function in cyclical environments. However, temperature order and cyclicity may influence physiological processes. The current study compared energy intake, digestive passage time, and energy budgets across stable temperature (30˚C, 33˚C, 36˚C) and two temperature cycles in lizards (<em>Sceloporus conosbrinus</em>), determining 1) if stable treatments adequately project performance in a cycling environment and 2) if temperature order influences performance. Cycles rotated through 30˚C, 33˚C, 36˚C daily, with equal durations of time at each temperature but differing temperature order, with warm days and cool nights in cycle 1 and cool days and warm nights in cycle 2. For analyses, stable treatments were compiled into a single dataset and compared to cycles. If temperature is the primary factor regulating performance, then performance averages from stable treatments and cycles should compare favorably. However, physiological performance varied based on temperature treatment. Intake and energy budgets were similar between stable trials and cycle 1 but not cycle two. Passage time was quicker in cycle 1 than cycle 2 and stable treatment predictions. Notably, the two cycling regimes consistently varied in performance, indicating that temperature order plays a primary role in regulating performance. Physiological data collection requires careful consideration of effects of cycling versus stable temperature treatments. Stable temperatures do not consistently represent performance in cycling regimes and consideration should be paid not only to which temperatures animals experience, but how temperature is experienced in nature.</p>
Seed mix design and floral resources drive multi-trophic interactions in prairie restoration
<ol> <li>Ecological restoration often targets plant community recovery, but restoration success may depend on the recovery of a complex web of biotic interactions to maintain biodiversity and promote ecosystem services. Specifically, management that drives resource availability, such as seeding richness and provenance, may alter species interactions across multiple trophic levels. Using experimentally seeded prairies, we examine three key groups – plants, pollinators, and goldenrod crab spiders (<em>Misumena vatia</em>, predators of pollinators) – to understand the effects of species richness and admixture seed sourcing of restoration seed mixtures on multi-trophic interactions.</li> <li>Working with prairie plants, we experimentally manipulated seed mix richness and the number of seed source regions (single-source region or admixture seed sourcing). In each experimental prairie, we surveyed floral abundance and richness, pollinator visitation, and plant-<em>M. vatia</em> interactions.</li> <li>A high-richness seed mix increased floral abundance when seeds were sourced from a single geographic region, and floral abundance strongly increased pollinator visitation, <em>M. vatia</em> abundance, and prey capture. Seeding richness and admixture seed sourcing of the seed mixture did not affect floral species richness, but floral species richness increased pollinator visitation.</li> <li>Pollinators interacted with different floral communities across seeding treatments, indicating a shift in visited floral species with restoration practices.</li> <li> <em>Synthesis and applications</em>. Long-term success in prairie restoration requires the restoration of plant-arthropod interactions. We provide evidence that seed mix richness and admixture seed sourcing affect arthropod floral associations, but effective restoration of plant-arthropod interactions should consider total floral resource availability. Incorporating a food web perspective in restoration will strengthen approaches to whole ecosystem restoration.</li> </ol>
The spatial ecology of Mojave Rattlesnakes (Crotalus scutulatus), Prairie Rattlesnakes (C. viridis), and their hybrids in southwestern New Mexico
<p>Hybridization between species provides unique opportunities to understand evolutionary processes that are linked to reproductive isolation and ultimately speciation. The extrinsic factors that limit hybridization, however, are poorly understood for most animal systems. Although the spatial ecology of individuals in natural habitats is fundamental to shaping reproductive success and survival, analyses of the spatial ecology of hybrids and their parental groups are rarely reported. Here we used radiotelemetry to monitor wild rattlesnakes across an interspecific hybrid zone (<em>Crotalus scutulatus </em>and <em>C. viridis</em>) and measured movement parameters and space use (Utilization Distributions, UDs) of individuals to evaluate the hypothesis that hybridization resulted in transgressive or atypical movement patterns. Unexpectedly, of the spatial metrics we investigated, we found that hybrids were very similar to parental individuals. Nonetheless, hybrids did show increased patchiness of core UDs, but this result is likely driven by increased habitat patchiness in the hybrid zone. Overall, we did not find evidence for overt extrinsic barriers to hybridization associated with spatial ecology; thus, we suggest that the close evolutionary history between the two parental species—and their ecological and behavioral similarities—likely increases the probability of hybridization events in this unique region of New Mexico.</p>

Effective dispersal patterns in prairie plant species across human-modified landscapes
<p>Effective dispersal among plant populations is dependent on vector behavior, landscape features, and availability of adequate habitats. To capture landscape feature effects on dispersal, studies must be conducted at scales reflecting single-generation dispersal events (meso-scale). Many studies are conducted at large-scales where genetic differentiation is due to dispersal occurring over multiple generations, making it difficult to interpret the effects of specific landscape features on vector behavior. Genetic structure at the meso-scale may be determined by ecological and evolutionary processes, such as the consequences of vector behavior on patterns of gene flow. We used chloroplast haplotypes and nuclear genome SNP surveys to identify landscape features influencing seed and pollen dispersal at a meso-scale within the Rogue River Valley in southern Oregon. We evaluated biotic and abiotic vector behavior by contrasting two annual species with differing dispersal mechanisms; <em>Achyrachaena mollis</em> (Asteraceae) is a self-pollinating and anemochoric species, and <em>Plectritis congesta</em> (Caprifoliaceae) is biotically pollinated with barochoric seeds. Using landscape genetics methods, we identified features of the study region that conduct or restrict dispersal. We found chloroplast haplotypes were indicative of historic patterns of gene flow prior to human modification of landscapes. Seed dispersal of <em>A. mollis</em> was best supported by models of isolation-by-distance, while seed-driven gene flow of <em>P. congesta</em> was determined by the distribution of preserved natural spaces and quality habitat. Whole-genome genetic structure was driven by both pollen and seed dispersal, and both species responded to contemporary landscape changes, such as urban and agricultural conversion, and habitat availability.</p>
Extirpated prairie species demonstrate more variable phenological responses to warming than extant congeners
<p><i>Premise of the study. </i>Shifting phenology in response to climate is one mechanism that can promote population persistence and geographic spread; therefore, species with limited ability to phenologically track changing environmental conditions may be more susceptible to population declines. Alternatively, apparently, nonresponding species may demonstrate divergent responses to multiple environmental conditions experienced across seasons.</p> <p><i>Methods. </i>Capitalizing on herbarium records from across the Midwestern United States and detailed botanical surveys documenting local extinctions over the past century, we investigate whether extirpated and extant taxa differ in their phenological responses to temperature and precipitation experienced during winter and spring (during flowering and the growing season prior to flowering) or in their magnitude of flowering time shift over the past century.</p> <p><i>Key results. </i>Although warmer temperatures across seasons advanced flowering, extirpated and extant species differed in the magnitude of their phenological responses to winter and spring warming. Extirpated species demonstrated inconsistent phenological responses to warmer spring temperatures. Meanwhile, extant species consistently advanced flowering in response to warmer spring temperatures. In contrast, extirpated species advanced flowering more than extant species in response to warmer winter temperatures. Greater spring precipitation tended to delay flowering for both extirpated and extant taxa. Finally, both extirpated and extant taxa delayed flowering over time.</p> <p><i>Conclusions. </i>This study highlights the importance of understanding phenological responses to seasonal warming and indicates that extirpated species may demonstrate more variable phenological responses to temperature than extant congeners, a finding consistent with the hypothesis that appropriate phenological responses may reduce species' likelihood of extinction.</p>

Data from: Grassland type and seasonal effects have a bigger influence on plant functional and taxonomical diversity than prairie dog disturbances in semi-arid grasslands
<p>Prairie dogs (Cynomys sp.) are considered keystone species and ecosystem engineers for their grazing and burrowing activities (summarized here as disturbances). As climate changes and its variability increases, the mechanisms underlying organisms' interactions with their habitat will likely shift. Understanding the mediating role of prairie dog disturbance on vegetation structure, and its interaction with environmental conditions through time, will increase knowledge on the risks and vulnerability of grasslands. Here, we compared how plant taxonomical diversity, functional diversity metrics and community-weighted trait means (CWM) respond to prairie dog C. mexicanus disturbance across grassland types and seasons (dry and wet) in a priority conservation semiarid grassland of Northeast Mexico. Our findings suggest that functional metrics and CWM analyses responded to interactions between prairie dog disturbance, grassland type and season, whilst species diversity and cover measures were less sensitive to the role of prairie dog disturbance. We found weak evidence that prairie dog disturbance has a negative effect on vegetation structure, except for minimal effects on C4 and graminoid cover, but which depended mainly on season. Grassland type and season explained most of the effects on plant functional and taxonomic diversity as well as CWM traits. Furthermore, we found that leaf area as well as forb and annual cover increased during the wet season, independent of prairie dog disturbance. Our results provide evidence that grassland type and season have a stronger effect than prairie dog disturbance on the vegetation of this short-grass, water restricted grassland ecosystem. We argue that focusing solely on disturbance and grazing effects is misleading, and attention is needed on the relationships between vegetation and environmental conditions which will be critical to understand semi-arid grassland dynamics under future climate change conditions in the region. </p>

Grassland bird population declines at three Breeding Bird Survey spatial scales in contrast to a large native prairie
<p>Grassland biomes in North America are threatened by agricultural intensification with implications for grassland associated bird populations via habitat loss, alteration, pesticide use and declining landscape heterogeneity. Despite decades of conservation concern, steep declines of North American grassland bird populations continue. Key to optimizing conservation effort is understanding how land-use practices, such as agriculture, across the annual cycle affects population status. Determining the relative influence of impacts on grassland bird declines is difficult given that the most robust estimates of population trends, the North American Breeding Bird Survey (BBS), are from surveys throughout agriculturally dominated regions. Our goal was to explore whether agriculture during the breeding season is a major driver of grassland bird declines. We derived trends for 16 grassland bird species spanning 23 years (1994-2016) at a large (459 km2), native prairie site, Suffield National Wildlife Area (SNWA) in Alberta, Canada. We compared those trends to the BBS across three spatial scales, a regional monitoring scheme with higher than average native grass cover (GBM), BCR 11 - Canada (Canada) and all of BCR 11 (BCR 11). Trends measured as annual percent change and credible interval varied greatly among species and survey strata. Across all species, declines were greatest for Canada (-1.3%, CI: -2.8, 0.0) and BCR 11 (-1.9%, CI: -3.2, -0.6). This contrasts with positive mean trends for GBM routes (1.0%, CI: -0.4, 2.3) and the SNWA data (1.7%, CI: 0.3, 3.3). Six of 16 species at SNWA were increasing with one decreasing. Five species increased at GBM and four declined. Canada had 10 species declines and three increases and BCR 11 had 10 declines and no increases. None of six grassland obligate species declined at SNWA, two declined at GBM, and all six declined over the two larger BBS strata. Our results showing fewer negative population trends at a large native grassland site compared to BBS at three spatial scales across the North American prairies support the prediction that agricultural intensification on breeding grounds is a major driver of declining populations and protection of remaining native grasslands should remain a key component of grassland bird conservation efforts.</p>

Data from: Mycorrhizal-herbivore interactions and the competitive release of subdominant tallgrass prairie species
<p>Plant-microbial-herbivore interactions play a crucial role in the structuring and maintenance of plant communities and biodiversity, yet these relationships are complex. In grassland ecosystems, herbivores have the potential to greatly influence the survival, growth, and reproduction of plants. However, few studies examine interactions of above- and belowground grazing and AM mycorrhizal symbiosis on plant community structure. We established experimental mesocosms containing an assemblage of eight tallgrass prairie grass and forb species in native prairie soil, maintained under mycorrhizal and nonmycorrhizal conditions, with and without native herbivorous soil nematodes, and with and without grasshopper herbivory. Using factorial analysis of variance and principal component analysis, we examined: a) the independent and interacting effects of above- and belowground herbivores on AM symbiosis in tallgrass prairie mesocosms, b) independent and interacting effects of above- and belowground herbivores and mycorrhizal fungi on plant community structure, and c) potential influences of mycorrhizal responsiveness of host plants on herbivory tolerance, and concomitant shifts in plant community composition. Treatment effects were characterized by interactions between AM fungi and both aboveground and belowground herbivores, while herbivore effects were additive. The dominance of mycorrhizal-dependent C<sub>4</sub> grasses in the presence of AMF symbiosis was increased (<em>p</em> < 0.0001) by grasshopper herbivory but reduced (<em>p</em> < 0.0001) by nematode herbivory. Cool-season C<sub>3</sub> grasses exhibited a competitive release in the absence of AMF symbiosis but this effect was largely reversed in the presence of grasshopper herbivory. Forbs showed species-specific responses to both AM fungal inoculation and the addition of herbivores. Biomass of the grazing-avoidant, facultatively mycotrophic forb <em>Brickellia eupatorioides</em> increased (<em>p</em> < 0.0001) in the absence of AMF symbiosis and with grasshopper herbivory, while AMF-related increases in the aboveground biomass of mycorrhizal-dependent forbs <em>Rudbeckia hirta</em> and <em>Salvia azurea</em> were eradicated (<em>p</em> < 0.0001) by grasshopper herbivory. In contrast, nematode herbivory enhanced (<em>p</em> = 0.001) the contribution of <em>Salvia azurea</em> to total biomass.</p> <p><em>Synthesis</em>: Our research indicates that AM symbiosis is the key driver of the dominance of C<sub>4</sub> grasses in the tallgrass prairie, with foliar and root herbivory being two mechanisms for the maintenance of plant diversity.</p>

Flexibility of cutaneous evaporative water loss in response to hydration in pregnant Prairie Rattlesnakes and their neonates
<p>Data and code associated with the paper published in the Journal of Experimental Biology in 2025.</p>
Data from: Fire, grazing, and climate shape plant-grasshopper interactions in a tallgrass prairie
1. Species interactions are integral to ecological community function and the structure of species interactions has repercussions for the consequences of species extinctions. Few studies have examined the role of environmental factors in controlling species interaction networks across time. 2. We examined variation in plant-grasshopper network structural properties in response to three major grassland drivers: periodic fire, ungulate grazing and climate. 3. We sequenced a plant barcoding gene from extracted grasshopper gut contents to characterize diets of 26 grasshopper species. Resulting grasshopper species' diets were combined with long-term plant and grasshopper surveys to assemble plant-grasshopper networks across 13-19 years for 6 watersheds subjected to varying fire and grazing treatments. 4. Network modularity, generality, and predicted grasshopper community robustness to plant species loss all increased in grazed watersheds. Temperature decreased predicted grasshopper community robustness to plant species loss. 5. Grasshopper communities were found to be vulnerable to climatic warming due to host plant loss. However, intermediate disturbance from ungulate grazers may maintain grasshopper diversity and buffer community robustness to species loss. Our results suggest that climate and disturbance shape the structure of ecological interaction networks and thus have many indirect effects on species persistence though direct effects on interaction partners.
