Disturbance in a cypress-tupelo wetland: An interaction between thermal loading and hydrology
The interaction between thermal loading and hydrology was examined in a forested wetland. As a result of flooding, portions of the wetland are periodically exposed to elevated water temperatures, resulting in ...

Response of wetland herbaceous communities to gradients of light and substrate following disturbance by thermal pollution
The influence of thermal disturbance and site characteristics on distribution of herbs was studied in portions of a 3020 ha wetland in the southeastern USA. Presence-absence of 52 species in 130 0.25 m2 plots was...

Correspondence between Vegetation and Soils in Wetlands and Nearby Uplands
The association between vegetation and soils from a geographically broad sampling of wetlands and adjoining uplands is reported for 38 hydric and 26 nonhydric soils, as recognized in the hydric soils list of t...

Fast, contention-free combining tree barriers for shared-memory multiprocessors
In a previous article,(1) Gupta and Hill introduced anadaptive combining tree algorithm for busy-wait barrier synchronization on shared-memory multiprocessors. The intent of the algorithm was to achieve a barrier...

Restoration of riparian forest using irrigation, artificial disturbance, and natural seedfall
In interior western North America, many riparian forests dominated by cottonwood and willow are failing to reproduce downstream of dams. We tested the hypothesis that establishment is now prevented by absence ...

Water Management and Cottonwood Forest Dynamics Along Prairie Streams
Because riparian ecosystems are the principal natural forest in the prairie, they provide important habitat for many vertebrates (Brinson et al. 1981). Thus changes in the abundance and patterns of riparian fo...

Constraints on establishment of plains cottonwood in an urban riparian preserve
Plot sampling and hydraulic modeling were combined to investigate establishment and survival of plains cottonwood along Boulder Creek, an urban stream on the Colorado Plains. We tested the hypothesis that esta...

Fluvial disturbance patches and cottonwood recruitment along the upper Missouri River, Montana
The disturbance patches most suitable for seedling establishment of pioneer riparian trees are also subject to future disturbances that produce high seedling mortality. We are monitoring plains cottonwood seed...

Downstream effects of dams on channel geometry and bottomland vegetation: Regional patterns in the great plains
The response of rivers and riparian forests to upstream dams shows a regional pattern related to physiographic and climatic factors that influence channel geometry. We carried out a spatial analysis of the res...

Responses of Riparian Cottonwoods to Alluvial Water Table Declines
Human demands for surface and shallow alluvial groundwater have contributed to the loss, fragmentation, and simplification of riparian ecosystems. Populus species typically dominate riparian ecosystems through...

InterWeave: A Middleware System for Distributed Shared State
As an alternative to message passing, Rochester’s InterWeave sys- tem allows the programmer to map shared segments into programs spread across heterogeneous, distributed machines. InterWeave represents a merge...

Nonblocking Concurrent Data Structures with Condition Synchronization
We apply the classic theory of linearizability to operations that must wait for some other thread to establish a precondition. We model such an operation as a request and a follow-up, each with its own linearizat...

Preemption Adaptivity in Time-Published Queue-Based Spin Locks
The proliferation of multiprocessor servers and multithreaded applications has increased the demand for high-performance synchronization. Traditional scheduler-based locks incur the overhead of a full context ...

Adaptive Software Transactional Memory
Software Transactional Memory (STM) is a generic synchronization construct that enables automatic conversion of correct sequential objects into correct nonblocking concurrent objects. Recent STM systems, though s...

Use of individualistic streamflow-vegetation relations along the Fremont River, Utah, USA to assess impacts of flow alteration on wetland and riparian areas
We analyzed the transverse pattern of vegetation along a reach of the Fremont River in Capitol Reef National Park, Utah, USA using models that support both delineation of wetland extent and projection of the c...

Dominance of non-native riparian trees in western USA
Concern about spread of non-native riparian trees in the western USA has led to Congressional proposals to accelerate control efforts. Debate over these proposals is frustrated by limited knowledge of non-nati...

Conflict Detection and Validation Strategies for Software Transactional Memory
In a software transactional memory (STM) system, conflict detection is the problem of determining when two transactions cannot both safely commit. Validation is the related problem of ensuring that a transaction ...

Transaction Safe Nonblocking Data Structures
This brief announcement focuses on interoperability of software transactions with ad hoc nonblocking algorithms. Specifically, we modify arbitrary nonblocking operations so that (1) they can be used both insid...
