Abstract: Coral reefs are one of the ecosystems most sensitive to climate change. The recent loss and degradation of coral reef ecosystems is expected to continue even if global warming is limited to 1.5°C above pre-industrial levels. There is therefore an urgent need to develop new technologies and management approaches to coral reef conservation. Emerging technologies, however, bring new challenges for decision making as they are associated with novel risks and impacts on the reef system. We argue that accounting for multiple biophysical thresholds and identifying key decisions in the planning process are crucial to avoid perverse outcomes in coral reef conservation. We identify opportunities to apply an Adaptation Pathways (AP) framework combined with a ‘values, rules and knowledge’ approach to facilitate long-term and large-scale coral reef conservation by explicitly considering uncertainty with climate change impacts in the decision-making process. The AP process can be used to reconcile the erse values of stakeholders, scientific and cultural knowledge about the system, and the policy and regulatory context within which management must occur, in order to achieve robust long-term management.

Abstract: Australia's Great Barrier Reef (GBR) catchments include some of the world's most intact coastal wetlands comprising erse mangrove, seagrass and tidal marsh ecosystems. Although these ecosystems are highly efficient at storing carbon in marine sediments, their soil organic carbon (SOC) stocks and the potential changes resulting from climate impacts, including sea level rise are not well understood. For the first time, we estimated SOC stocks and their drivers within the range of coastal wetlands of GBR catchments using boosted regression trees (i.e. a machine learning approach and ensemble method for modelling the relationship between response and explanatory variables) and identified the potential changes in future stocks due to sea level rise. We found levels of SOC stocks of mangrove and seagrass meadows have different drivers, with climatic variables such as temperature, rainfall and solar radiation, showing significant contributions in accounting for variation in SOC stocks in mangroves. In contrast, soil type accounted for most of the variability in seagrass meadows. Total SOC stock in the GBR catchments, including mangroves, seagrass meadows and tidal marshes, is approximately 137 Tg C, which represents 9%–13% of Australia's total SOC stock while encompassing only 4%–6% of the total extent of Australian coastal wetlands. In a global context, this could represent 0.5%–1.4% of global SOC stock. Our study suggests that landward migration due to projected sea level rise has the potential to enhance carbon accumulation with total carbon gains between 0.16 and 0.46 Tg C and provides an opportunity for future restoration to enhance blue carbon.

Abstract: This work studied the use of the Babitonga Bay (26º02’-26º28’S and 48º28’-48º50’W) by early life stages of Sciaenidae, considering the spatial-temporal distribution of species and their relationship with environmental factors. S les were obtained at nine stations between October 2007 and August 2008, with 2 minutes oblique tows using a 40cm diameter conical plankton net fitted with 200µm mesh and 2 five minutes oblique tows with a 50cm diameter cylindrical-conical plankton net fitted with 500µm mesh. A total of 249 fish larvae of Sciaenidae were captured, being Cynoscion spp. (50%), Umbrina spp. (16%) e Stellifer spp. (17,6%) the most abundant taxa. Fish larvae showed the highest densities during spring and summer months, and occupied the whole estuary. Temperature and salinity were the main factors structuring the distribution of Sciaenidae larvae. Preflexion stage was the most abundant, but vitelinic, flexion and postflexion larvae were also reported. The presence of different early life stages of Sciaenidae in Babitonga Bay reveals the important role of this ecosystem as a nursery for target species of South-Southeast Brazil fisheries.

Abstract: There is a growing interest in including blue carbon ecosystems (i.e., mangroves, tidal marshes and seagrasses) in climate mitigation programs in national and sub-national policies, with restoration and conservation of these ecosystems identified as potential activities to increase carbon accumulation through time. However, there is still a gap on the spatial scales needed to produce carbon offsets comparable with terrestrial or agricultural ecosystems. Here, we used the Coastal Blue Carbon InVEST 3.7.0 model to estimate future net carbon sequestration in blue carbon ecosystems along Australia's Great Barrier Reef (hereafter GBR) catchments, considering different management scenarios (i.e., reintroduction of tidal exchange through the removal of barriers, sea level rise, restoring low lying land) at three different spatial scales: whole GBR coastline, regional (14,000-16,300 ha), and local (335-370 ha) scales. The focus of the restoration (i.e., tidal marshes and/or mangroves) was dependent on data availability for each scenario. Furthermore, we also estimated the monetary value of carbon sequestration under each management scenario and spatial scale assessed in the study. We found that large scale restoration of tidal marshes could potentially sequester an additional ∼800,000 tonnes of CO

Abstract: O zooplâncton é um importante elo nas teias tróficas aquáticas, além de representar uma parcela considerável da bio ersidade. No presente estudo, revisamos o conhecimento sobre a comunidade zooplanctônica no estuário da Babitonga e áreas costeiras adjacentes visando fornecer subsídios para elaboração de planos de conservação e manejo locais. O estudo do zooplâncton na região é recente, desde 2002, com maior esforço amostral no canal principal do estuário. Um total de 261 espécies foram registrados até o momento, sendo 159 invertebrados e 102 larvas de peixes, incluindo sete espécies exóticas. A região ainda carece de estudos, principalmente nas áreas mais internas do estuário, bem como para ersos grupos taxonômicos (e.g. moluscos, quetognatos, apendiculárias) e aspectos como interações tróficas e simbióticas, reprodução, produção secundária, dinâmica populacional, padrões de flutuação em curto e longo-prazo, e a influência de eventos climáticos e mudanças climáticas na composição, distribuição e abundância das espécies.

Abstract: The Mediterranean‐type climate region of Chile is a globally unique bio ersity hotspot but its protected area system does not adequately represent the biological ersity, nor does it provide equitable access to people. We explored options to expand the protected area system to cost‐effectively improve the conservation of forest ecosystem types while simultaneously enhancing social accessibility to protected areas. Social accessibility is defined as the access of municipalities to cultural ecosystem services provided by protected areas which depends on distance to highly demanded protected areas and income of the municipalities. Using systematic conservation planning methods, we identified priority areas for extending the existing protected area system that: (a) minimise land acquisition cost, (b) maximise social accessibility and (c) optimise for both cost and accessibility. The results show that it is possible to improve social accessibility while simultaneously minimising land cost. Considering cost alone, the protected area system could be expanded to improve bio ersity conservation by 86% at the cost of $47 million USD, which would also increase the accessibility of protected areas by 12%. Accessibility can be increased by a further 18% by jointly considering cost and accessibility without compromising the cost or bio ersity performance. New private conservation policy developed in Chile could help offset the costs of conservation through novel public–private partnerships. Our results can provide specific guidance to policymakers to strategically identify new locations for protected areas which cost‐effectively improve bio ersity conservation, while at the same time reducing inequality in social accessibility. The consideration of social access in reserve design could increase the success of protected areas as a conservation tool by bringing people closer to nature.

Abstract: O estuário da Baía Babitonga desempenha um papel importante para a ictiofauna da região, sendo evidenciado pela elevada abundância de in íduos juvenis registrados na área de estudo. No presente trabalho, apresentamos uma revisão bibliográfica sobre a ictiofauna estuarina e marinha presente no Ecossistema Babitonga (Baía Babitonga e áreas marinhas adjacentes). Foram analisados 62 estudos de ictiofauna realizados no Ecossistema Babitonga, os quais abrangeram diferentes setores e ambientes: praias estuarinas e arenosas, ambientes rasos, entremarés e de baixa energia ambientes recifais (costões rochosos e parcéis) canal principal do estuário e plataforma continental externa e interna. No total, foram identificadas 287 espécies e 86 famílias, cuja presença no ambiente foi caracterizada em termos da heterogeneidade e ersidade espacial e temporal, estrutura trófica, produtividade, e as pressões antrópicas no nível das populações, comunidades e/ou metapopulação. 28 espécies merecem atenção especial para a gestão em função do nível de ameaça ou da importância socioeconômica. As informações levantadas a partir desta revisão permitiram também a identificação das lacunas de conhecimento e as ações prioritárias para a conservação da bio ersidade de peixes no Ecossistema Babitonga.

Abstract: Artisanal fisheries support millions of livelihoods worldwide, yet ineffective enforcement can allow for continued environmental degradation due to overexploitation. Here, we use spatial planning to design an enforcement strategy for a pre-existing spatial closure for artisanal fisheries considering climate variability, existing seasonal fishing closures, representative conservation targets and enforcement costs. We calculated enforcement cost in three ways, based on different assumptions about who could be responsible for monitoring the fishery. We applied this approach in the Patos Lagoon estuary (Brazil), where we found three important results. First, spatial priorities for enforcement were similar under different climate scenarios. Second, we found that the cost and percentage of area enforced varied among scenarios tested by the conservation planning analysis, with only a modest increase in budget needed to incorporate climate variability. Third, we found that spatial priorities for enforcement depend on whether enforcement is carried out by a central authority or by the community itself. Here, we demonstrated a method that can be used to efficiently design enforcement plans, resulting in the conservation of bio ersity and estuarine resources. Also, cost of enforcement can be potentially reduced when fishers are empowered to enforce management within their fishing grounds.
