Integrated agricultural riparian stewardship in the Stillaguamish and Snohomish watersheds
The Stillaguamish and Snohomish River watersheds are regionally important to the health of Puget Sound and the Salish Sea and in particular for the recovery of salmon. The habitat gains needed to achieve salmon recovery in these watersheds include much of the agricultural landscape in Snohomish County, a situation that often results in conflicts between salmon recovery and agricultural communities. The Snohomish Conservation Districtâs National Estuary Program-funded Integrated Riparian Stewardship project is one of several efforts aimed at simultaneously achieving agricultural land preservation and salmon habitat protection and restoration in one of the fastest growing counties in the United States, where pressures from development and climate change threaten both salmon recovery and agriculture, and where agricultural property owners may feel salmon recovery efforts impact their livelihood and way of life. The District and project partners undertook a planning and protection/restoration initiative to identify, protect, and restore high priority riparian agricultural and rural lands in the Stillaguamish and Snohomish watersheds. The District developed an Action Plan that identifies high priority areas for reach-scale riparian protection and restoration and outlines a comprehensive riparian zone management approach for three focus areas in the Stillaguamish and Snohomish watersheds. The Action Plan integrates existing geomorphic, habitat, hydrologic, and water quality studies to identify reaches and parcels on which to purchase conservation easements and complete habitat restoration projects in order to protect or enhance cold water inflows, restore salmon habitat, and improve or protect hydrologic processes. The District is currently implementing the Action Plan. We will share our experience with a precision outreach strategy and our successes in leveraging the easement program with grant funding and the Conservation Reserve Enhancement Program and other grant funding to secure landowner cooperation and achieve reach-scale riparian zone management. Partners include Snohomish County, Washington Department of Ecology, Forterra, and NOAA Restoration Center
A Framework for Establishing Restoration Goals for Contaminated Ecosystems
This article represents 1 of 6 articles in the special series âRestoration of Impaired Ecosystems: An Ounce of Prevention or a Pound of Cure?â The articles result from a Technical Workshop organized by SETAC and the Society for Ecological Restoration, held June 2014 in Jackson, Wyoming, that focused on advancing the practice of restoring ecosystems that have been contaminated or impaired from industrial activities.As natural resources become increasingly limited, the value of restoring contaminated sites, both terrestrial and aquatic, becomes increasingly apparent. Traditionally, goals for remediation have been set before any consideration of goals for ecological restoration. The goals for remediation have focused on removing or limiting contamination whereas restoration goals have targeted the ultimate end use. Here, we present a framework for developing a comprehensive set of achievable goals for ecological restoration of contaminated sites to be used in concert with determining goals for remediation. This framework was developed during a Society of Environmental Toxicology and Chemistry (SETAC) and Society of Ecological Restoration (SER) cosponsored workshop that brought together experts from multiple countries. Although most members were from North America, this framework is designed for use internationally. We discuss the integration of establishing goals for both contaminant remediation and overall restoration, and the need to include both the restoration of ecological and socio-cultural-economic value in the context of contaminated sites. Although recognizing that in some countries there may be regulatory issues associated with contaminants and clean up, landscape setting and social drivers can inform the restoration goals. We provide a decision tree support tool to guide the establishment of restoration goals for contaminated ecosystems. The overall intent of this decision tree is to provide a framework for goal setting and to identify outcomes achievable given the contamination present at a site.

An evaluation of recruitment indices for Northeast Arctic cod (Gadus morhua L.)
Indices of the abundance of Northeast Arctic cod (Gadus morhua L.) for various life
stages were compared in order to determine the earliest stage at .which year-class
strength is established. The indices considered are: VPA estimates of spawning stock
biomass; an egg abundance index; an early juvenile (approximately three-months old)
abundance index; 0-group (age four to five months) abundance indices; bottom trawl
and acoustic survey abundance indices for one, two and three- year-old cod and VPA
estimates of the abundance of three-year-old cod. Based on a regression analysis, the
relative abundance of early juvenile cod was the first life stage that was correlated
with their relative'abundance as three year olds. Since the cokelation between the
estimates of spawning stock biomass or total egg production and the relative
abundance of three-year-old cod was weak, it is concluded that considerable yearly
variation in mortality occurs before cod reach the early juvenile stage
Exploring Perceived Importance of a Novel Emergency Food Program during COVID-19 and Program Recipient Characteristics
Following rising unemployment rates and consequent loss of income due to COVID-19, many people have been seeking meal assistance. This study examines the impact of a community-based free meal distribution program during the pandemic in Kentucky, reviewing characteristics of recipients of the program. Demographics, health behaviors, food insecure classification, and rating of importance of the meal program were collected. Qualitative feedback on the impact of the program was collected via open response. Of the 92 participants using the meal service, the cohort was female, Black, 43 years of age (43.5 ± 15.0 years), with a household income under 30,000 USD before COVID, decreased income since COVID, and were food insecure. Recipients rated the importance of the service as 8.7 ± 1.8 (of 10), and those with children indicated the importance as 4.2 ± 1.1 (of 5). Qualitative data on program importance highlighted four response categories including âchanged habitsâ, âmental wellbeingâ, âprovided resourcesâ, and âotherâ. In response to the COVID-19 pandemic, many individuals have struggled. Meal assistance programs are a fundamental asset in the community that have seen marketed demand since COVID-19. Collaboration with, and evaluation of, meal assistance programs can be valuable for continued programmatic funding support
Tissue-specific calibration of extracellular matrix material properties by transforming growth factor-beta and Runx2 in bone is required for hearing

Perturbation of these cues underlies diverse pathologies, including osteoarthritis, cardiovascular disease and cancer. However, the molecular mechanisms that establish tissue-specific material properties and link them to healthy tissue function are unknown. We show that Runx2, a key lineage-specific transcription factor, regulates the material properties of bone matrix through the same transforming growth factor-beta (TGFbeta)-responsive pathway that controls osteoblast differentiation. Deregulated TGFbeta or Runx2 function compromises the distinctly hard cochlear bone matrix and causes hearing loss, as seen in human cleidocranial dysplasia. In Runx2(+/-) mice, inhibition of TGFbeta signalling rescues both the material properties of the defective matrix, and hearing. This study elucidates the unknown cause of hearing loss in cleidocranial dysplasia, and demonstrates that a molecular pathway controlling cell differentiation also defines material properties of extracellular matrix. Furthermore, our results suggest that the careful regulation of these properties is essential for healthy tissue functio
IACHEC CROSS-CALIBRATION OF CHANDRA, NuSTAR, SWIFT, SUZAKU, XMM-NEWTON WITH 3C 273 ANDPKS 2155-304
On behalf of the International Astronomical Consortium for High Energy Calibration, we present results from the cross-calibration campaigns in 2012 on 3C 273 and in 2013 on PKS 2155-304 between the then active X-ray observatories Chandra, NuSTAR, Suzaku, Swift, and XMM-Newton. We compare measured fluxes between instrument pairs in two energy bands, 1â5 keV and 3â7 keV, and calculate an average cross-normalization constant for each energy range. We review known cross-calibration features and provide a series of tables and figures to be used for evaluating cross-normalization constants obtained from other observations with the above mentioned observatories.United States.

Thinking big and thinking small: A conceptual framework for best practices in community and stakeholder engagement in food, energy, and water systems
Community and stakeholder engagement is increasingly recognized as essential to science at the nexus of food, energy, and water systems (FEWS) to address complex issues surrounding food and energy production and water provision for society. Yet no comprehensive framework exists for supporting best practices in community and stakeholder engagement for FEWS. A review and metaâsynthesis were undertaken of a broad range of existing models, frameworks, and toolkits for community and stakeholder engagement. A framework is proposed that comprises situational awareness of the FEWS place or problem, creation of a suitable culture for engagement, focus on powerâsharing in the engagement process, coâownership, coâgeneration of knowledge and outcomes, the technical process of integration, the monitoring processes of reflective and reflexive experiences, and formative evaluation. The framework is discussed as a scaffolding for supporting the development and application of best practices in community and stakeholder engagement in ways that are arguably essential for sound FEWS science and sustainable management
