Macroalgae Decrease Growth and Alter Microbial Community Structure of the Reef-Building Coral, Porites astreoides

This is the publisher’s final pdf. The published article is copyrighted by the Public Library of Science and can be found at: http://www.plosone.org/home.action.With the continued and unprecedented decline of coral reefs worldwide, evaluating the factors that contribute to coral demise is of critical importance. As coral cover declines, macroalgae are becoming more common on tropical reefs. Interactions between these macroalgae and corals may alter the coral microbiome, which is thought to play an important role in colony health and survival. Together, such changes in benthic macroalgae and in the coral microbiome may result in a feedback mechanism that contributes to additional coral cover loss. To determine if macroalgae alter the coral microbiome, we conducted a field-based experiment in which the coral Porites astreoides was placed in competition with five species of macroalgae. Macroalgal contact increased variance in the coral-associated microbial community, and two algal species significantly altered microbial community composition. All macroalgae caused the disappearance of a γ-proteobacterium previously hypothesized to be an important mutualist of P. astreoides. Macroalgal contact also triggered: 1) increases or 2) decreases in microbial taxa already present in corals, 3) establishment of new taxa to the coral microbiome, and 4) vectoring and growth of microbial taxa from the macroalgae to the coral. Furthermore, macroalgal competition decreased coral growth rates by an average of 36.8%. Overall, this study found that competition between corals and certain species of macroalgae leads to an altered coral microbiome, providing a potential mechanism by which macroalgae-coral interactions reduce coral health and lead to coral loss on impacted reefs

Local Air Quality Management policy and practice in the UK: The case for greater Public Health integration and engagement

© 2016 Elsevier Ltd. The UK's Local Air Quality Management (LAQM) regime is designed to protect people's health from the ill-effects of air pollution, but it is failing to achieve its full potential. The Public Health aspects of, perspectives on, and integration and engagement in, LAQM have been poorly considered to date. This critical literature review assessed LAQM-related strengths and limitations in order to explore how Public Health, through greater integration and engagement, can add value to the regime.'Structure' and 'process' weaknesses were identified, including: A poorly defined Public Health role, a narrowly-scoped prescribed process, risk assessment uncertainties, ineffective communications, shallow evaluations and disconnected policies. Separately and cumulatively, these have hindered Public Health integration in LAQM policy and practice and stunted the regime's evolution. Engaging Public Health in LAQM future design and delivery can help solve these problems, by improving risk assessments and raising awareness of air pollution and other health-influencing relationships, targeting action in high-need areas, coordinating air pollution mitigation and health improvement interventions, and connecting different policy areas.Increasing Public Health integration and engagement in LAQM can enhance the existing regime. Acting now is timely from both LAQM and Public Health perspectives. This review's findings should be used to inform debates and decisions around the future development of Local Air Quality Management arrangements both in the UK and beyond

How UK climate change policy has been made sustainable

UK climate change policy is based on the advice of the Committee on Climate Change established under the Climate Change Act 2008. This Committee is an independent, expert agency established as part of the reconceiving of the regulatory state as a response to the neo-liberal critique of older forms of regulation. But the quality of the advice given in the Committee’s recent Fourth Carbon Budget Review is so tendentious as to barely be able to be described as advice at all. This grave shortcoming poses the most serious questions for contemporary constitutional and regulatory processes

High Abundances of Species in Protected Areas in Parts of their Geographic Distributions Colonized during a Recent Period of Climatic Change

It is uncertain whether Protected Areas (PAs) will conserve high abundances of species as their distributions and abundances shift in response to climate change. We analyzed large datasets for 57 butterfly and 42 odonate species (including four that have recently colonized Britain). We found that 73 of 94 species with sufficient data for analysis were more abundant inside than outside PAs in the historical parts of their British distributions, showing that PAs have retained high conservation value. A significant majority (61 of 99 species) was also more abundant inside PAs in regions they have colonized during the last 30–40 years of climate warming. Species with relatively high abundances inside PAs in long-established parts of their distributions were also disproportionately associated with PAs in recently colonized regions, revealing a set of relatively PA-reliant species. Pas, therefore, play a vital role in the conservation of biodiversity as species’ ranges become more dynamic

Calcium to phosphorus ratio, essential elements and vitamin D content of infant foods in the UK: possible implications for bone health

Adequate intake of calcium and phosphorus in the appropriate ratio of 1–2:1 (Ca:P), in addition to magnesium and vitamin D, is vital for bone health and development of infants. In this feasibility study, the ratio of Ca:P in conjunction with vitamin D and other essential elements (Cu, Fe, K, Mg, Na, and Zn) in a range of commercial infant food products in the UK was investigated. The elemental analysis was carried out using inductively coupled plasma optical emission spectrometry, and vitamin D levels were determined using an enzyme-linked immunosorbent assay. The quantitative data were further evaluated, based on a standardised menu, to measure the total daily intake of an infant aged 7–12 months against the Reference Nutrient Intake. The results from the study show that the Ca:P ratio of the infant's total dietary intake was within the recommended range at 1.49:1. However, the level of intake for each of the nutrients analyzed, with the exception of sodium, was found to be above the Reference Nutrient Intake, which warrants further investigation in relation to both micronutrient interactions and in situations where the intake of fortified infant formula milk is compromised. Finally, as the study is the first to include consumption of infant snack products, the level of total calorie intake was also calculated in order to assess the total daily estimated energy intake; the results indicate that energy intakes exceed recommendations by 42%, which may have implications for obesity

Private finance for the delivery of school projects in England

This paper analyses the use of the private finance initiative (PFI) approach to deliver school projects in England. The findings are based on case-study research in the Building Schools for the Future scheme (BSF), the largest single capital investment in SO years to rebuild and renew all of England's secondary schools. Up to half of the school infrastructure is to be procured by PFI contracts. A major concern has been the high cost associated with PFI procurement and any subsequent changes to scope. Furthermore, in some cases PFI-funded schools have been closed soon after completion; at great cost to the public sector. The aim of this research was therefore to understand the underlying reasons for these problems. The main conclusion is that the difficulties in BSF arise from not sorting out strategic issues and instituting appropriate organisational frameworks before engaging the private sector. The result of this is a lack of clarity about the long-term needs and end user aspirations. A brief outline of current programme management methods is given and it is suggested that this might be integral to the successful delivery of schools using private finance. A clear strategic vision that cascades into projects via programmes will ensure that the school infrastructure is appropriate for the anticipated strategic benefits and is aligned to the overall service delivery ambitions

Of embodied emissions and inequality: rethinking energy consumption

This paper situates concepts of energy consumption within the context of growing research on embodied emissions. Using the UK as a case study I unpack the global socio-economic and ecological inequalities inherent in the measurement of greenhouse gas emissions on a territorial basis under the international climate change framework. In so doing, I problematise questions of distribution, allocation and responsibility with regards to the pressing need to reduce global GHG emissions and the consumption that generates them. I challenge the disproportionate emphasis that energy policy places on supply as opposed to demand, as well as its overriding focus on the national scale. Consequently I argue that any low carbon transition, in addition to a technological process, is also a geographical one that will involve the reconfiguration of "current spatial patterns of economic and social activity" (Bridge et al., 2013:331), as well as relationships both within countries and regions and between them
