A terrestrial ecologist plays an important role in natural channel design by conducting background reviews, field surveys, and producing an existing conditions report prior to the design. This informs the selection of plant species for revegetation that are not rare, tolerate site conditions, and emulate natural assemblages. Timing windows must also be considered to avoid impacts to breeding birds, amphibians, and snakes. The ecologist helps determine existing constraints and ensures the design appropriately conserves natural features along the river.

In 2011, CVC began using long-term data loggers to monitor pollution events in streams within the Kiski-Conemaugh River Basin. As part of the program, CVC collected macro-invertebrate samples from each logger site in the spring and fall of the year to begin assessing biological integrity of the monitored streams and attaining baseline data. Throughout the program, several unknown impacts were recorded using the data loggers and confirmed with macro-invertebrates. In 2014, CVC began to sample fish at logger monitoring locations to complete biological baseline data collection, confirm and diagnose stream pollutants and assess reclamation efforts. The comparison of the logger and biological data is allowing CVC to more accurately diagnose pollutants and pinpoint critical areas for reclamation efforts within the Kiski-Conemaugh River Basin, while building a chemical and biological baseline for the Basin.Концепция фирменного стиля Республики Татарстан 2

Local Government
This chapter discusses local government in the United States. It covers the types of local governments including counties, municipalities, and special districts. It then examines the different forms of governance for local governments such as mayor-council systems, commission systems, and council-manager systems. The chapter concludes that while local governments are constrained, they also provide important services to citizens and reflect the political culture of their communities.

Bernardo Cruz descreve sua viagem à Hungria com sua escola como parte do projeto Comenius. Ele achou Budapeste uma cidade incrível com monumentos históricos impressionantes e gostou especialmente de um passeio noturno de barco pelo rio Danúbio. Ele também apreciou conhecer um campeão olímpico húngaro e visitar um estúdio de cinema, embora tenha achado a comida pouco apetitosa. No geral, ele considerou a viagem uma experiência única que nunca esquecerá.
Lincoln douglas debates
Stephen Douglas, who had developed the Kansas-Nebraska Act, ran for re-election to the Senate in 1858 against Abraham Lincoln. Douglas supported "popular sovereignty" but opposed the pro-slavery Lecompton Constitution for Kansas, while still believing whites were superior to blacks. Lincoln had little political experience but was nominated by the Republican Party to challenge Douglas. Lincoln and Douglas debated across Illinois on the issue of slavery, with Lincoln showing Douglas did not truly understand "popular sovereignty" given the Dred Scott decision, and that the US could not survive with half slave and half free states. Douglas won re-election but Lincoln emerged as a national figure for his moral arguments against slavery.

This document summarizes a lecture on forces and moments transmitted by slender members. It defines slender members as long, skinny structural elements like skis, golf clubs, and I-beams. It discusses axial forces that act along the member's axis, shear forces that act in the plane of the member's face, and bending moments. Sign conventions for these internal loads are also defined. An example is provided to demonstrate calculating the internal forces and moments in a beam by setting up free body diagrams at different points.

Freshwater protected areas and defining a conservation blueprint for desert f...University of Washington
This document summarizes a study that aimed to identify priority areas for conserving freshwater fish diversity in the Lower Colorado River Basin. The study developed species distribution models for 40 native and non-native fish species. Using these models and metrics of taxonomic, functional, and phylogenetic diversity, a conservation prioritization algorithm identified the top conservation priorities. The study found opportunities for conservation but also trade-offs between different diversity targets and challenges from contemporary and future threats.Meeting presentation. 2011. Ecological Services of Weeds
This document discusses the ecological services provided by weeds and non-native plants. It notes that while weeds are typically managed to reduce their negative impacts, they can also provide important benefits by providing food, shelter, nesting sites, and perching areas for native wildlife. The document explores various examples of wildlife utilizing weeds and recommends management modifications like altering the timing, intensity, proportion or scale of weed control activities to maintain these ecological services while still meeting management goals. The goal is to recognize and preserve the wildlife value weeds can provide through a "dual goals" approach to management.

The core of this project is a long-term common garden experiment.
Monday, February 12 3:05 - 3:30 p.m.Development of an Interagency Biological Observation and Site Analysis Workflow
The document discusses developing a way to count biological observations and sites of sensitive and special status species on US Forest Service and Bureau of Land Management land. There are two separate databases—BLM's GeoBOB and USFS's NRM—that need to be standardized and analyzed. The task is broken into three conceptual phases: extract and standardize the data, analyze the standardized data, and visualize the analysis. While finding the general approach is the "easy problem", dealing with documentation, requirements, and other details is the "real problem" that requires an iterative design-build process using exploratory workspaces and consulting subject matter experts.
Scientific Poster of Bauer and Stanley
The document summarizes baseline ecological surveys conducted in 2014 at the University of Portland's River Campus riparian zone, a former Superfund site undergoing restoration. Surveys inventoried 22 woody plant species (90% in poor health), recorded 139 herbaceous plant species from 42 families including 29% natives, and observed 31 avian species and 3988 invertebrates from 16 orders. Methods were developed to monitor vegetation, birds, and insects to establish baseline data and assess ecological recovery over time. While mainly exotic species were present, several native plants and species were colonizing. Future surveys will compare data to these baselines to evaluate restoration success and riparian habitat recovery.
OWLT Final Presentation
The document analyzes landcover types in northern Milwaukee River watershed that provide benefits for natural areas. It finds that forest, grassland, and wetland protection are critical for wildlife habitat, retaining runoff, and protecting rare species. A team identified key natural areas and used a land fragmentation tool to find core forest, grassland, and wetland parcels over 35 acres for conservation. Their analysis found parcels containing combinations of these landcover types.

Assessing Botanical and Pollinator Communities in ROW Habitats
This document summarizes a study assessing the effects of integrated vegetation management (IVM) practices on pollinator and botanical communities in rights-of-way (ROW) habitats. The study involved butterfly, bee, and vegetation surveys along transects in ROWs to track biodiversity changes over three seasons. Results showed various pollinator groups including butterflies, bees, flies and beetles present in the ROWs. Milkweeds and nectar resources varied by season. Habitat composition was biased towards pollinator habitats. Future directions include increasing data resolution, using baseline data to track long-term changes, and emphasizing training to improve survey consistency. The study demonstrates that ROWs can provide valuable wildlife habitat when

This document summarizes research on the phylogeography of the bat genus Myotis. The study analyzed genetic data from over 100 Myotis species to construct phylogenetic trees showing evolutionary relationships worldwide. Model-based analyses estimated divergence times and traced geographic origins. Results suggest Myotis originated in the Oriental region over 15 million years ago and subsequently dispersed throughout Eurasia, Africa, Australia, and the Americas. This research provides insight into the evolution and biogeography of the highly diverse and globally distributed Myotis genus.

Bird Behaviour and Mortality Monitoring
Natural Resource Solutions Inc. conducted post-construction bird and bat mortality surveys from 2006 to 2008 at the Prince Wind Farm located in Sault Ste. Marie, Ontario. They found 236 bat carcasses and 72 bird carcasses over the study period. Accounting for searcher efficiency and scavenger removal, total estimated bat and bird mortalities were 452 and 167 respectively. The majority of bat and bird fatalities were little brown bats and passerine birds. Mortality rates were similar to other open agricultural wind farms and below rates in forested areas. Bird behavior and breeding surveys found no evidence of negative impacts from the wind turbines.

The document discusses different monitoring techniques used to study bats at wind power projects, including acoustic monitoring, night vision monitoring, and radar monitoring. It provides an overview of each technique, the challenges associated with each, and lessons learned from integrating multiple techniques. Acoustic monitoring relies on detecting ultrasonic calls, night vision uses low-light devices, and radar can track bat movements but has limitations discriminating bats from birds. Combining the techniques provides more comprehensive results, but bat monitoring generates large amounts of complex data that require significant analysis time.
Nrsi can wea2010_mortality(stephenson)1
1) Natural Resource Solutions Inc. has participated in post-construction mortality monitoring at wind farms since 2006 and has experience monitoring over 4000MW of projects in multiple provinces.
2) There are several important considerations for monitoring including search radius, asymmetry of carcasses found, searcher efficiency, scavenger removal, and high adjustment factors resulting from these studies.
3) The document recommends testing the search radius, including full coverage of the area under turbines, frequent searcher and scavenger tests, using replicates to tighten confidence limits, and emphasizing tightening confidence limits on adjustment factors.

Baerwald et al 2009 large scale mitigation experiment
This document summarizes a study that tested methods to reduce bat fatalities at wind turbines. Researchers altered the operational parameters of 21 turbines at a wind farm in Alberta, Canada during peak bat migration season. For 15 turbines, the wind speed needed for the rotors to start turning was increased from 4 to 5.5 m/s, keeping the rotors motionless in lower winds. For 6 turbines, the blade pitch angle was adjusted to reduce rotor speed in low winds. Both methods significantly reduced bat fatalities, by 60% and 58% respectively, compared to unaltered control turbines. The increased rotor start-up speed treatment reduced turbine operational hours by 42% during the study period. The results suggest altering turbine operation in low winds
Arnett et al 2008 effectiveness changing cut in speed reduce fatalities
This document summarizes a study that tested changing wind turbine cut-in speeds to reduce bat fatalities at a wind facility in Pennsylvania. Researchers found that fatalities were 5.4 times greater at fully operational turbines compared to turbines with cut-in speeds of 5.0 or 6.5 m/s. Estimated total bat fatalities per turbine were 1.23-4.68 times greater at control turbines that were fully operational compared to curtailed turbines. The power lost from changing cut-in speeds for the study period was estimated to be a marginal percentage of total annual output. The study demonstrated that nightly bat fatality can be reduced 53-87% with minimal power loss, though more research is needed to evaluate

The document summarizes bird and bat monitoring results from the Prince Wind Farm project in Timmins, Ontario between 2006-2008. It describes the monitoring program conducted by Natural Resource Solutions Inc. including pre and post-construction surveys of birds, bats and other wildlife. Post-construction monitoring found low levels of bird and bat mortality at the wind farm, below averages seen at other forested wind projects. Bird behavior monitoring showed some avoidance during construction but no significant changes in bird populations or behavior post-construction.
Pdf template Invoice
The document provides tips and best practices for working with PDF templates and the Forms Data Format (FDF). It discusses how FDF files can be used to dynamically generate new PDF pages from templates, populate form fields, and programmatically import FDF data. Key points include renaming fields when spawning template pages to avoid conflicts, using the original field names from templates when populating data, and calling FDFAddTemplate before FDFSetValue when constructing an FDF file to dynamically create pages.
