Changes in Seagrass Species Composition in Northwestern Gulf of Mexico Estuaries: Effects on Associated Seagrass Fauna

The objective of this study was to measure the communities associated with different seagrass species to predict how shifts in seagrass species composition may affect associated fauna. In the northwestern Gulf of Mexico, coverage of the historically dominant shoal grass (Halodule wrightii) is decreasing, while coverage of manatee grass (Syringodium filiforme) and turtle grass (Thalassia testudinum) is increasing. We conducted a survey of fishes, crabs, and shrimp in monospecific beds of shoal, manatee, and turtle grass habitats of South Texas, USA to assess how changes in sea grass species composition would affect associated fauna. We measured seagrass parameters including shoot density, above ground biomass, epiphyte type, and epiphyte abundance to investigate relationships between faunal abundance and these seagrass parameters. We observed significant differences in communities among three seagrass species, even though these organisms are highly motile and could easily travel among the different seagrasses. Results showed species specific relationships among several different characteristics of the seagrass community and individual species abundance. More work is needed to discern the drivers of the complex relationships between individual seagrass species and their associated fauna

The orbit of consumer credit choices

Resulting from instability in the UK financial climate in recent times, consumers have increasingly turned to alternative credit sources such as payday loans, logbook loans (car title loans) and pawning. Recognising this increasingly important trend in UK society, this study explores how UK consumers manage and select alternative credit sources, through a Consumer Culture Theory lens. Primary data were sourced through a multi-stage interview process with ten consumers of alternative credit providers. Findings were subjected to a rigorous six-stage thematic analysis, which enabled generation of a three-ring orbit model showing how the consumers migrated between categories of credit sources. Furthermore, it was found that other concepts could be traced on to the orbit model, such as access to other credit sources, time pressures, perceived risk and emotional state. It is expected that the findings from this study will benefit lenders, policy makers and regulatory bodies from greater insights into understanding of the emotional state of their customers and the particularly the pressures they may be experiencing when taking last resort credit sources
