Tale of two species of Stylissa (Porifera: Demospongiae: Scopalinida) from the west and east coasts of India.

Recent collections from the western and southern coasts of India recorded two species of Stylissa Hallmann (Scopalinida, Scopalinidae). Stylissa soestii sp. nov. was collected from St. George Island in Goa, Hare Island in the Gulf of Mannar and the Palk Bay. It has six distinct different morphologies and sizes of styles, in addition to the typical gently curved stout and thin styles characteristic of Stylissa, and two different morphologies of strongyloxeas and rare strongyles. Stylissa carteri (Dendy, 1889) was reported previously from India (Gulf of Mannar and Pearl Banks of Tuticorin) and is redescribed here from populations in Palk Bay, east coast of India, in addition to Muttom, Vizhinjam and Lakshadweep islands, which are the first records of S. carteri from the west coast of India.

A checklist of marine sponges (Porifera) of peninsula India.

An inventory of sponges from the shallow subtidal reefs of the west and east coasts of southern India is presented. The specimens offered in this paper were based on in-situ collections unlike the previous records of dry and net-entangled collections. A total of 101 species belonging to 12 orders, 22 families, 5 subfamilies and 44 genera from 4 subclasses of Class Demospongiae and one species from Class Calcarea are recorded. We recorded 18 new records to India, six new species combinations, 37 potential new records, and 40 species for the first time from the southwest coast.

The politics of food in the Pacific: coherence and tension in regional policies on nutrition, the food environment and non-communicable diseases.

OBJECTIVE: Our study analysed evolving regional commitments on food policy in the Pacific. Our aim was to understand regional priorities and the context of policy development, to identify opportunities for progress. DESIGN: We analysed documentation from a decade of regional meetings in order to map regional policy commitments relevant to healthy diets. We focused on agriculture, education, finance, health, and trade sectors, and Heads of State forums. Drawing on relevant political science methodologies, we looked at how these sectors 'frame' the drivers of and solutions to non-communicable diseases (NCD), their policy priorities, and identified areas of coherence and tension. SETTING: The Pacific has among the highest rates of non-communicable diseases in the world, but also boasts an innovative and proactive response. Heads of State have declared NCD a 'crisis' and countries have committed to specific prevention activities set out in a regional 'Roadmap'. Yet, diet-related NCD risk-factors remain stubbornly high and many countries face challenges in establishing a healthy food environment. RESULTS: Policies to improve food environments and prevent NCD are a stated priority across regional policy forums, with clear agreement on the need for a multi-sectoral response. However, we identified challenges in sustaining these priorities as political attention fluctuated. We found examples of inconsistencies and tension in sectoral responses to the NCD epidemic that may restrict implementation of the multi-sectoral action. CONCLUSION: Understanding the priorities and positions underpinning sectoral responses can help drive a more coherent NCD response, and lessons from the Pacific are relevant to public health nutrition policy and practice globally.

Not so sweet refrain: sugar-sweetened beverage taxes, industry opposition and harnessing the lessons learned from tobacco control legal challenges.

As a growing number of countries implement, or announce plans to introduce, a sugar-sweetened beverage (SSB) tax, this paper explores the public health rationale for such a tax and provides an overview of the international normative and policy instruments supporting the introduction of fiscal measures on sugary drinks. After examining parallels between the legal arguments raised by the food and beverage industry in opposition to SSB taxes and those raised by the tobacco industry in response to tobacco control measures, this paper draws four key lessons that will assist countries to design effective and robust SSB tax measures and counter food and beverage industry opposition: regulatory distinctions in tax coverage should be based on bona fide, evidence-based reasoning; evidence-based measures need to be tailored to a country's public health objectives as part of a comprehensive strategy to address unhealthy diet consumption; procedural requirements and due process should be observed in the drafting and implementation of the measure; and regulatory space exists within domestic constitutions, laws and international trade and investment agreements recognising the sovereign right of states to regulate in the interests of public health.

Amphipoda living in sponges on the Great Barrier Reef, Australia (Crustacea, Amphipoda).

Fourteen species of amphipod are recorded as endocommensal with the sponges Coelocarteria singaporensis, Coscinoderma mathewsi and Ircinia microconulosa on the Great Barrier Reef. The genus Leucothoe is represented by three new species, one specific to each of the three sponges. Hyperadult males of Aoroides parvus Myers are also described.
