- Abstract:
- ... Fairy rings are conspicuous features of the Laramie Basin of southeastern Wyoming. Ten fairy ring sites chosen for intensive study were located using a small plane and 415 whole and partial fairy rings were georeferenced and ground-truthed. Fairy ring forming fungi were identified using a combination of taxonomy and ITS fungal barcode sequence comparisons. Precipitation, vegetation, soil type, ele ...

- Abstract:
- ... Ongoing climate change is increasing rainfall variability in many parts of the world; in particular, the heaviest rainfall events are becoming heavier. In terrestrial ecosystems, nitrogen deposition is increasing as a result of emissions from fossil fuel burning and volatilization of nitrogen‐based fertilizers. These changes in the timing and rate of resource inputs can impact plant communities by ...

- Abstract:
- ... The delineation of precipitation regions is to identify homogeneous zones in which the characteristics of the process are statistically similar. The regionalization process has three main components: (i) delineation of regions using clustering algorithms, (ii) determining the optimal number of regions using cluster validity indices (CVIs), and (iii) validation of regions for homogeneity using L-mo ...

- Abstract:
- ... Grassland ecosystems globally are being negatively impacted by changes in climate, disturbance regimes, nutrient flux, and consumer guilds. Changes in the trophic ecology of consumers can substantially influence local resources, contributing to shifting diversity, community turnover, and other processes of ecosystem change. Small mammals are diverse and abundant within grasslands and yet the impac ...

- Abstract:

We examined if reintroduction of grazing with or without burning would enhance succession towards native prairie vegetation on previously over-seeded old-field tallgrass prairie subjected to mowing or burning. We hypothesized that returning grazing and fire to these seeded and old-field sites would change establishment and competitive relationships among plant species to benefit fire-tolerant prai ...

- Abstract:
- ... Restored habitats require long-term management to maintain biodiversity and ensure ecosystem functions. Management strategies are often developed for plant communities, including through seeding and disturbance management, but these actions are taken with a focus on plant dynamics and with little knowledge of the effects on non-plant organisms. Wild bees are often expected to respond to such manag ...

Yet, few genotype by environment interaction studies quantify differences in the shape of plasticity functions or phenotypic breakpoints across genotypes in natural populations. Using three genotypes with a history of drought selection, we performed a ...

- Abstract:

However, little is known of the relative effects of seasonal variation in water isotopes on estimates of lake hydrology, particularly over decadal scales. To address this gap, we measured water isotopes bi-w ...

- Abstract:

Mitigating fragmentation is difficult, however, because population responses depend on species-level traits (e.g., dispersal ability, edge sensitivity) and landscape context (e.g., habitat amount). Thus, conservation requires determining not only if, but also where and why, fragmentation matters. O ...

- Abstract:

Restoration is a relatively new process to convert agricultural land back to communities dominated by native vegetation. We used a differential equations compartmental model to quantify changes between land use types, incorporating the impact ...

- Abstract:
- ... Live-trapping of rodents is facilitated by their thigmotaxis (i.e. the tendency to walk along linear structures of the habitat). However, in open habitats, such as meadows and prairies, where linear structures (e.g. rocks and fallen branches) are generally absent and where densities are likely to be low, capturing rodents is often very demanding or ineffective. This applies especially to semifosso ...

Collaborative adaptive management (CAM) is hypothesized to benefit management of rangeland ecosystems, but the presumed benefits have seldom been quantified, and never in a multipaddock rotational grazing system.
