Defining seascapes for marine unconsolidated shelf sediments in an eastern boundary upwelling region: The southern Benguela as a case study( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract: Marine unconsolidated sediment habitats, the largest benthic ecosystem, are considered physically controlled ecosystems driven by a number of local physical processes. Depth and sediment type are recognised key drivers of these ecosystems. Seascape (i.e., marine landscape) habitat classifications are based solely on consistent geophysical features and provide an opportunity to define unconsolidated sediment habitats based on processes which may vary in distribution through space and time. This paper aimed to classify unconsolidated sediment seascapes and explore their diversity in an eastern boundary upwelling region at the macro-scale, using the South African west coast as a case study. Physical variables such as sediment grain size, depth and upwelling-related variables (i.e., maximum chlorophyll concentration, austral summer bottom oxygen concentration and sediment organic carbon content) were included in the analyses. These variables were directly measured through sampling, or collated from existing databases and the literature. These data were analysed using multivariate Cluster, Principal Components Ordination and SIMPER analyses (in PRIMER 6+with PERMANOVA add-in package). There were four main findings; (i) eight seascapes were identified for the South African west coast based on depth, slope, sediment grain size and upwelling-related variables, (ii) three depth zones were distinguished (inner, middle and outer shelf), (iii) seascape diversity in the inner and middle shelves was greater than the outer shelf, and (iv) upwelling-related variables were responsible for the habitat diversity in both inner and middle shelves. This research demonstrates that the inclusion of productivity and its related variables, such as hypoxia and sedimentary organic carbon, in seascape classifications will enhance the ability to distinguish seascapes on continental shelves, where productivity is most variable. Graphical abstract: Highlights: We defined sediment seascapes on an eastern boundary upwelling region (EBUR) shelf. We distinguished three depth zones, i.e. the inner, middle and outer shelves. Seascape diversity in the inner and middle shelves was greater than the outer shelf. Upwelling-related variables defined both inner and middle shelf seascapes. Include productivity in seascape classifications to represent continental shelves

Using multivariate statistics to explore trade-offs among spatial planning scenarios( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Scenario planning can be useful to guide decision-making under uncertainty. While systematic conservation planning can create protected-area networks for multiple and complex reserve-design scenarios, planners rarely compare different reserve networks explicitly, or quantify trade-offs among scenarios. We demonstrate the use of multivariate statistics traditionally applied in community ecology to compare reserves designed under different scenarios, using conservation planning for beaches in South Africa as an example. Twelve reserve-design scenarios were run in Marxan in a hierarchical experimental design with three levels: including/excluding the probability of site destruction; two different cost types; and three different configurations of existing terrestrial and marine reserves. Multivariate statistics proved to be useful tools in the conservation planning context. In our case study, they showed that the trade-off associated with including the probability of site destruction during coastal reserve design depended on the cost type: if the cost is related to the site-destruction probability then reserves are significantly larger; if not, then reserves are significantly more costly. In both cases, the configuration of existing reserves locked a priori into the solutions was more important and resulted in significantly larger and more costly reserves. Synthesis and applications. This study demonstrates a novel application of multivariate statistical tools to robustly quantify potential trade-offs among diverse sets of reserve-design scenarios. These statistics can be applied: to support negotiations with stakeholders and decision-makers regarding reserve configurations in the face of uncertainty; in reserve-design sensitivity analyses; and in priority setting for future research and data collection to improve conservation plans
