Coral communities and reefs from Guerrero,Southern Mexican Pacific

Corals in the Eastern Pacific extend south from the Gulf of California to Ecuador and oceanic Chile, and west from Colombia to Clipperton Atoll. Nevertheless, large stretches of the Mexican Pacific remain fundamentally unstudied. Therefore, to assess the current conditions of coral communities, a coastal fringe ～300 km long (17°40′ N, 101°39′ W to 16°46′ N, 99°49′ W) was surveyed within the Southern Mexican Pacific, between 2005 and 2009. Fifteen stony coral species were identified at 13 coral communities and six Pocillopora‐dominated fringing reefs, with Pocillopora verrucosa and Pocillopora damicornis the primary contributing taxa. Reef development was identified in embayments or behind rocks or islands that offered shelter from northern and northwestern winds. Observations of Pocillopora effusus, Pocillopora inflata, Porites lobata, Pavona clavus, and Pavona varians expanded the species known geographic ranges by several degrees of latitude, suggesting reef building fauna comprised a mixture of widespread and relatively rare Eastern Pacific corals. Results indicated greater live coral cover in the Ixtapa‐Zihuatanejo area (15–73%) than in the Acapulco localities, which had high algal dominance; the reefs in the latter region exhibited high erosion. Regional differences are likely the result of long‐standing anthropogenic pressures around Acapulco since 1950, when it became an important tourist destination. This paper is the first detailed report of ecologically stressed corals and coral reefs from the state of Guerrero on the Mexican Southern Pacific coast.     

Shifting accountabilities? Understanding the connections between national and provincial fisheries in Papua New Guinea

This paper examines the effects of fisheries decentralization strategies in Papua New Guinea. The paper assess the financial, human resources, information, and institutional mechanisms that the National Fisheries Authority uses to connect with provincial fisheries offices to show the consequences of institutional reforms. The findings suggest both intended and unintended effects, particularly in terms of shifting accountabilities and loyalty. These findings are broadly applicable to decentralization and institutional change scholars and practitioners interested in understanding how governments implement institutional change reforms and the effects of this implementation.

Cost Shifting in Australian Local Government: an analysis of the spatial impact of pensioner rate concession rebates in New South Wales,Australia

The problem of cost shifting from higher tiers of government to local councils in Australia is widely recognised and has been investigated by several official inquiries. However, it has thus far been difficult to gather reliable estimates of the magnitude of the problem. Quite apart from the taxing definitional and data problems associated with the phenomenon, these difficulties have been compounded by the fact that very few attempts have been made to measure the impact of specific instances of cost shifting in Australian local government, especially its spatial impact. In an attempt to remedy this neglect, this paper seeks to measure the spatial effects of pensioner rate concession rebates on local councils in New South Wales.     

'There is a tide': An examination of the evolution of New Zealand Coastal Policy Statements

Abstract:   In this paper the proposed New Zealand Coastal Policy Statement is set within the context of its Resource Management Act legislative framework and in terms of the evolution of the fundamental influence of policy statements on coastal management in New Zealand. This discussion is coupled with an examination of the development of strong policy directions in the proposed statement and the potential impact of giving effect to these policies on the regional and unitary authorities tasked with this responsibility.     

Regional dynamics in the globalising wine industry: the case of Marlborough, New Zealand

The rapid expansion of the New Zealand wine industry has rested largely on a specific wine commodity form, Marlborough Sauvignon Blanc. Global demand for a specialised product has provided the impetus for substantial development at the regional level, an increasingly complex industry structure, and for the intrusion of international capital. This paper explores the contests and relations within the industry through attention to the commodity's value-added chain, wherein recent developments are interpreted as a contest over the brand rents. The contemporary situation therefore may be explained through overlapping organisational and geographic framings of these relations: producer versus buyer-driven dynamics; regional–national and global interests; and inter- and intra-corporate strategies. The commercial contest for control of the region-varietal commodity reveals some paradoxical outcomes in which the region is reaffirmed as a site of investment in an evidently globalised industry, and the significance of who controls what fraction of the value chain is re-asserted.     

Flows,system boundaries and the politics of urban metabolism: Waste management in Mexico City and Santiago de Chile

In this paper we examine two central concepts of urban metabolism (‘system boundaries’ and ‘flows’), and explore how to approach them as a means to politicise urban metabolism research. We present empirical findings from two case studies of waste management, in Mexico City and Santiago de Chile, looking at: the materiality of waste flows, the actors involved in them, and how waste flows relate to issues of environmental justice. We argue that urban metabolism, as a methodology to understand urban sustainability, has the potential to produce knowledge to trigger urban transformations, and to analyse the social, political and environmental aspects of waste management in urban areas.     

The geographies of difference in conflating digital and offline spaces of encounter: Migrant professionals' throwntogetherness in Singapore

This article explores the effects of people's digital coexistence on the construction of difference and feelings of aversion to or recognition of “others”. It seeks to make a theoretical contribution to works on the geographies of difference and encounter, Internet or digital geography, as well as on migration and digital media, by highlighting the relevance of indirect and fleeting digital encounters and the dialectical process in which encounters play out in intertwined, specific and multiple digital and physical spaces that we define as “cON/FFlating situational places of encounter”. Based on a qualitative study with Chinese, Filipino and German migrant professionals in Singapore, it shows how fleeting digital encounters take an ambivalent role through challenging but also producing new “temporary fixings of difference”. As such they can engender new sensibilities for and openness toward the host society but also breed new, or aggravate existing, cultural stereotypes and prejudices. The findings show that inherited and instituted classificatory practices that people use to structure and make sense of their fleeting interactions with others in offline space are, where possible, transferred and imposed on encounters in digital space. At the same time, they are inflected or replaced with new markers of difference where ingrained sorting mechanisms applied in offline space did not help them make sense of encounters in digital space.     

Re-reading remittances through solidarity: Mexican hometown associations in New York City

This paper analyzes how Mexican hometown associations in New York City practice solidarity so that they might best meet the needs of the transnational communities that they serve. Commonly formed by immigrants in the United States, hometown associations are organizations which send money collectively to their home countries, supporting public infrastructure and community projects. Scholars have debated both the merits of remittance programs that channel migrant funds as economic development and the agency of immigrant economies in neoliberal development structures. Through primary data collected from interviews in New York City, I review the frustrations that hometown associations have with one such program: Mexico's programa tres por uno para migrantes. Concurrently, I examine how the same hometown associations engage ethical economic practices of collective remittance sending and community service provision in New York City. Drawing on feminist literature on diverse economies, I argue that the solidarity work of hometown associations disrupts the dominant remittance as development discourse. Migrants are not content to participate in tres por uno and through practicing solidarity they distance themselves from this neoliberal policy.     

Taphonomic history of a ‘duck-bill’ dinosaur (Dinosauria: Ornithopoda) from the Cerro del Pueblo Formation (Upper Cretaceous,Campanian) Coahuila,Mexico: Preservational and paleoecological implications

The Cerro del Pueblo Formation in the state of Coahuila, Mexico is becoming recognized worldwide due to its abundant and diverse fossil material. While most previous paleontological work from this rock unit has been directed towards taxonomic investigation, this study is directed towards the taphonomy of a “duck-billed” dinosaur (Ornithischia: Hadrosauridae). The hadrosaur skeleton is represented by several skull bones, vertebrae and ribs, a scapula, pubis, and various appendicular elements. The following taphonomic parameters were considered: (1) bone frequency; (2) hydraulic equivalence; (3) degree of bone articulation; (4) abrasion; (5) weathering; (6) breakage; (7) tooth marks; and (8) trampling activities. The low degree of weathering and abrasion suggests that the specimen experienced a short time of subaerial exposure and underwent a short transportation distance before deposition. Burial occurred within a perimarine lagoonal environment. Furthermore, the lack of hydraulic equivalence with the rock matrix, a high degree of disarticulation and a chaotic distribution of the bones in the fossiliferous bed, suggest that it was transported as a “bloated carcass”. The finding of distinct types of tooth marks evidence some sort of predator/scavenging activities on the specimen. Finally, an almost vertical orientation of various bones and the presence of spiral fractures may indicate that these elements were trampled by other animals.
