AbstractMatrix approaches are useful for linking ecosystem services to habitats that underpin their delivery. Matrix applications in marine ecosystem services research have been primarily qualitative, focusing on ‘habitat presence’ without including other attributes that effect service potential. We developed an evidence-based matrix approach of Ecosystem Service Potential (ESP) for New Zealand benthic marine habitats, and used two marine reserves to demonstrate that integrating information on the spatial extent and quality of habitats improved ESP evaluation. The two case studies identified substantial spatio-temporal variability in ESP: within one reserve, specific ESP showed an approximately 1.5-fold increase in the 29 years following protection. A comparison of two reserves found that the spatial extent of habitats contributing to the medicinal resources and waste-water treatment were 5 and 53 times greater respectively in one relative to the other. Integrating habitat area and quality with the ESP matrix improves on previous marine matrix-based approaches, providing a better indication of service potential. The matrix approach helps to communicate the non-market value of supporting and regulating services and can be used by resource managers to identify and track the potential for benefits derived from benthic marine habitats within existing, or new, marine protected areas.

Non-sectarian scenario experiments in socio-ecological knowledge building for multi-use marine environments: Insights from New Zealand's Marine Futures projectLe Heron, Richard; Lewis, Nick; Fisher, Karen; Thrush, Simon; Lundquist, Carolyn; Hewitt, Judi; Ellis, Joanne (Marine Policy, Elsevier BV, 2016-01-29) [Article]The challenges of managing marine ecosystems for multiple users, while well recognised, has not led to clear strategies, principles or practice. The paper uses novel workshop based thought-experiments to address these concerns. These took the form of trans-disciplinary Non-Sectarian Scenario Experiments (NSSE), involving participants who agreed to put aside their disciplinary interests and commercial and institutional obligations. The NSSE form of co-production of knowledge is a distinctive addition to the participatory and scenario literatures in marine resource management (MRM). Set in the context of resource use conflicts in New Zealand, the workshops assembled diverse participants in the marine economy to co-develop and co-explore the making of socio-ecological knowledge and identify capability required for a new generation of multi-use oriented resource management. The thought-experiments assumed that non-sectarian navigation of scenarios will resource a step-change in marine management by facilitating new connections, relationships, and understandings of potential marine futures. Two questions guided workshop interactions: what science needs spring from pursuing imaginable possibilities and directions in a field of scenarios, and what kinds of institutions would aid the generation of science knowledge, and it application to policy and management solutions. The effectiveness of the thought- experiments helped identify ways of dealing with core problems in multi-use marine management, such as the urgent need to cope with ecological and socio-economic surprise, and define and address cumulative impacts. Discussion focuses on how the workshops offered fresh perspectives and insights into a number of challenges. These challenges include building relations of trust and collective organisation, showing the importance of values-means-ends pathways, developing facilitative legislation to enable initiatives, and the utility of the NSSEs in informing new governance and management directions in multi-use marine environments.
From marine deserts to algal beds: Treptacantha elegans revegetation to reverse stable degraded ecosystems inside and outside a No-Take marine reserveMedrano, Alba; Hereu, Bernat; Cleminson, Maria; Pagès-Escolà, Marta; Rovira, Graciel·la; Solà, Jordi; Linares, Cristina (Restoration Ecology, Wiley, 2020-02-21) [Article]Canopy-forming algae play a key role in temperate coastal ecosystems sustaining complex habitats that provide food and refuge for rich associated biotic communities. These macroalgae are in decline in many coastal areas, where overgrazing by herbivores can lead to the loss of these highly structured and diverse habitats toward less complex sea urchin barren grounds. Once established, low productive barren grounds are considered stable states maintained by several positive feedback mechanisms that prevent the recovery of marine forests. To revert this global decline, restoration efforts and measures are being encouraged by EU regulations and local actions. Here, we tested the success of active revegetation techniques as a tool to promote functional and productive Treptacantha elegans forests in sea urchin barren grounds under different restoration strategies (active, and combined active with passive strategies). Active revegetation was performed in 6 barren grounds, 3 located inside a Mediterranean No-Take marine reserve (active and passive strategy) and 3 outside (active strategy alone), following a three-step protocol: (1) sea urchin population eradication, (2) seeding with Treptacantha elegans, and (3) enhancement of T. elegans recruitment. Revegetation success was assessed 1 year later in the six barren grounds, but was only achieved after combining active with passive restoration strategies. Our results encourage revegetation of barren grounds to shift from less productive habitats to complex T. elegans forests, highlight the potential of the combined passive and active restoration strategies, as well as the important role of marine reserves not only in conservation but also in ecological restoration.
Compositional Similarities and Differences between Transparent Exopolymer Particles (TEP) from two Marine Bacteria and two Marine Algae: Significance to Surface BiofoulingLi, Sheng; Winters, Harvey; Villacorte, L.O.; Ekowati, Y.; Emwas, Abdul-Hamid M.; Kennedy, M.D.; Amy, Gary L. (Marine Chemistry, Elsevier BV, 2015-06-14) [Article]Transparent-exopolymer-particles (TEP) have been recently identified as a significant contributor to surface biofouling, such as on reverse osmosis (RO) membranes. TEP research has mainly focused on algal TEP/TEP precursors while limited investigations have been conducted on those released by bacteria. In this study, TEP/TEP precursors derived from both algae and bacteria were isolated and then characterized to investigate their similarities and/or differences using various advanced analytical techniques, thus providing a better understanding of their potential effect on biofouling. Bacterial TEP/TEP precursors were isolated from two species of marine bacteria (Pseudidiomarina homiensis and Pseudoalteromonas atlantica) while algal TEP/TEP precursors were isolated from two marine algae species (Alexandrium tamarense and Chaetoceros affinis). Results indicated that both isolated bacterial and algal TEP/TEP precursors were associated with protein-like materials, and most TEP precursors were high-molecular-weight biopolymers. Furthermore all investigated algal and bacterial TEP/TEP precursors showed a lectin-like property, which can enable them to act as a chemical conditioning layer and to agglutinate bacteria. This property may enhance surface biofouling. However, both proton nuclear magnetic resonance (NMR) spectra and the nitrogen/carbon (N/C) ratios suggested that the algal TEP/TEP precursors contained much less protein content than the bacterial TEP/TEP precursors. This difference may influence their initial deposition and further development of surface biofouling.
