Food web ecology of Gulf Stream flounder (Citharichthys arctifrons): a continental shelf perspective.

Gulf Stream flounder, Citharichthys arctifrons, are regularly observed in fish diets of the northeast U.S. continental shelf, yet lack commercial value and are often ignored. Similarly, Gulf Stream flounder diets of the Northwest Atlantic have remained largely unexamined, except for a brief period from 1976 to 1980. To better understand their role in the ecosystem, juvenile through adult Gulf Stream flounder were examined both as a predator and prey, and the magnitude of their feeding footprint (removal of prey biomass) was quantified for the northeast U.S. continental shelf. Their stomachs were sampled from 2005 to 2010, with the majority examined in the field macroscopically. Due to large proportions of unidentifiable prey, the effort was expanded in 2011-2012, and all stomachs were processed in the laboratory microscopically. Gulf Stream flounder were consumed by 15 fish, and what they eat (percentage mass and percentage frequency of occurrence) was documented by season, spatial region and year. Highly benthivorous, Gammaridea and Polychaeta dominated the diet in all years, seasons and regions, but Ophiuroidea (brittle stars) were also prominent in Southern New England during the spring. Gulf Stream flounder diets remained consistent across regions and time, with only a few feeding differences between seasons and one region. Relative to the productivity of benthos for this shelf ecosystem, the feeding footprint of Gulf Stream flounder was minor for their predominant benthic prey with a maximum percentage of benthos production eaten of 0.01% m-2 in Southern New England. With an ecosystem perspective, this feeding information offers a foundation for improving fisheries management among shared living marine resources considering benthic habitat and prey availability.

Education and social inclusion of people with disabilities in five countries in West Africa: a literature review.

PURPOSE: An estimated 1 billion people worldwide live with some form of disability. With the adoption of the Sustainable Development Goals and the "Leave no one behind" agenda, there is a global momentum to ensure that disadvantaged groups, not least people with disabilities, are included and accounted for, in mainstream development efforts. However, in many low-income settings little is known about disability and the policies and programs in place to improve the lives of those affected. METHOD: This literature review describes the extent and quality of published and unpublished literature on education and social inclusion of people with disabilities in five West African countries: Cameroon, Liberia, Mali, Sierra Leone and Senegal. RESULTS: Fifty-four unique documents met inclusion criteria of the review and described related policy and legislation; national and international stakeholders; intervention programs and primary research related to disability and inclusion. The majority of documents were from Sierra Leone (19); and four described more than one country. Primary research included mainly qualitative studies and cross-sectional surveys; 33 sources were critically appraised with the majority being attributed unclear risk of bias (20). CONCLUSIONS: The findings call for (i) standardized tools for monitoring the implementation of programs and policies at national level; (ii) improved stakeholder coordination mechanisms; (iii) development and adoption of coordinated approaches to measuring disability and social exclusion; (iv) rigorous evaluations of the effectiveness of disability programs and (v) disaggregation of routine data by disability. Implication for Rehabilitation There is a need for standardized tools for monitoring the implementation of programs and policies at national level. Countries that have not yet ratified the UNCRPD or the protocol should be supported to do so. Stakeholder coordination mechanisms need to be improved. Improved coordination between stakeholders involved in disability at the country level could help improve the quality of services delivered. Development and adoption of coordinated approaches is key to measuring disability and social exclusion. There are few, if any, rigorous evaluation of the effectiveness of disability-specific evaluations in the five countries. There is a need for disaggregation of routine data from development programs by disability to inform implementation.
