- Cumulative pressures from global climate and ocean change combined with multiple regional and local-scale stressors pose fundamental challenges to coral reef managers worldwide. Understanding how cumulative stressors affect coral reef vulnerability is critical for successful reef conservation now and in the future. In this review, we present the case that strategically managing for increased ecological resilience (capacity for stress resistance and recovery) can reduce coral reef vulnerability (risk of net decline) up to a point. Specifically, we propose an operational framework for identifying effective management levers to enhance resilience and support management decisions that reduce reef vulnerability. Building on a system understanding of biological and ecological processes that drive resilience of coral reefs in different environmental and socio-economic settings, we present an Adaptive Resilience-Based management (ARBM) framework and suggest a set of guidelines for how and where resilience can be enhanced via management interventions. We argue that press-type stressors (pollution, sedimentation, overfishing, ocean warming and acidification) are key threats to coral reef resilience by affecting processes underpinning resistance and recovery, while pulse-type (acute) stressors (e.g. storms, bleaching events, crown-of-thorns starfish outbreaks) increase the demand for resilience. We apply the framework to a set of example problems for Caribbean and Indo-Pacific reefs. A combined strategy of active risk reduction and resilience support is needed, informed by key management objectives, knowledge of reef ecosystem processes and consideration of environmental and social drivers. As climate change and ocean acidification erode the resilience and increase the vulnerability of coral reefs globally, successful adaptive management of coral reefs will become increasingly difficult. Given limited resources, on-the-ground solutions are likely to focus increasingly on actions that support resilience at finer spatial scales, and that are tightly linked to ecosystem goods and services.

- Resilience underpins the sustainability of both ecological and social systems. Extensive loss of reef corals following recent mass bleaching events have challenged the notion that support of system resilience is a viable reef management strategy. While resilience-based management (RBM) cannot prevent the damaging effects of major disturbances, such as mass bleaching events, it can support natural processes that promote resistance and recovery. Here, we review the potential of RBM to help sustain coral reefs in the 21st century. We explore the scope for supporting resilience through existing management approaches and emerging technologies and discuss their opportunities and limitations in a changing climate. We argue that for RBM to be effective in a changing world, reef management strategies need to involve both existing and new interventions that together reduce stress, support the fitness of populations and species, and help people and economies to adapt to a highly altered ecosystem.

- Although autism spectrum disorders (ASDs) have a substantial genetic basis, most of the known genetic risk has been traced to rare variants, principally copy number variants (CNVs). To identify common risk variation, the Autism Genome Project (AGP) Consortium genotyped 1558 rigorously defined ASD families for 1 million single-nucleotide polymorphisms (SNPs) and analyzed these SNP genotypes for association with ASD. In one of four primary association analyses, the association signal for marker rs4141463, located within MACROD2, crossed the genome-wide association significance threshold of P < 5 × 10(-8). When a smaller replication sample was analyzed, the risk allele at rs4141463 was again over-transmitted; yet, consistent with the winner's curse, its effect size in the replication sample was much smaller; and, for the combined samples, the association signal barely fell below the P < 5 × 10(-8) threshold. Exploratory analyses of phenotypic subtypes yielded no significant associations after correction for multiple testing. They did, however, yield strong signals within several genes, KIAA0564, PLD5, POU6F2, ST8SIA2 and TAF1C.

Changes in adaptive capacity of Kenyan fishing communities

- Coastal communities are particularly at risk from the impacts of a changing climate(1). Building the capacity of coastal communities to cope with and recover from a changing environment is a critical means to reducing their vulnerability(2,3). Yet, few studies have quantitatively examined adaptive capacity in such communities. Here, we build on an emerging body of research examining adaptive capacity in natural resource-dependent communities in two important ways. We examine how nine indicators of adaptive capacity vary: among segments of Kenyan fishing communities; and over time. Socially disaggregated analyses found that the young, those who had migrated, and those who do not participate in decision-making seemed least prepared for adapting to change in these resource-dependent communities. These results highlight the most vulnerable segments of society when it comes to preparing for and adapting to change in resource-dependent communities. Comparisons through time showed that aspects of adaptive capacity seemed to have increased between 2008 and 2012 owing to higher observed community infrastructure and perceived availability of credit.

Adaptive capacity for social and environmental change : The role of networks in Chile’s small-scale fisheries
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- World’s small-scale fisheries (SSF) face permanent and increasing external changes and shocks that challenge their viability and potential as an engine of human sustainable development. It is broadly assumed and expected that fishers and their communities have the capacity to adapt to current and future social and ecological changes. While social networks and social capital have been regarded as key components of adaptive capacity in SSF, there is little empirical understanding of how they operate and of their effectiveness in the context of multiple and overlapping perturbations. This thesis examines the role of social networks and social capital in explaining the performance and responses of fisher organizations and communities to the implementation of a resource co-management policy, to the varied impacts of an abrupt coastal disaster, and to the interaction of both drivers. It consists of five papers that analyze the successes and failures of small-scale fisher organizations in the central-south of Chile in adapting and responding to the Management and Exploitation Areas for Benthic Resources system and to the massive February 2010 earthquake and tsunami. Paper I explores the levels of linking and bridging social capital among fisher organizations in Valparaiso and Bio-Bío regions, and their correlation with co-management performance variables. Paper II describes the material devastation of existing SSF capacity caused by the tsunami, and identifies the factors associated with immediate evacuation responses (i.e. incl. bonding social capital) that explain high levels of survival among fishing communities in the O’Higgins, Maule and Bio-Bío regions. Paper III studies how the interplay between internal (i.e. linking social capital) and external factors (i.e. levels of damage and isolation) can help explain differences in post-disaster recovery of fisher organizations in the Bio-Bío. Paper IV assesses whether and how co-management governance networks changed in the Bio-Bío as a consequence of tsunami impacts, as compared to the non-impacted case of Valparaiso. Paper V investigates the particular case of permanent earthquake-driven ecosystem transformations in a coastal wetland in Bio-Bío, the associated impacts on ecosystem services and human well-being, and the livelihood responses of fishing and non-fishing groups. The findings show that developing broad and strong social networks and building social capital are necessary conditions of SSF organizations and communities’ response and adaptive capacities in the face of policy changes and environmental disasters. However, the study also indicates that they are not sufficient in and of themselves, which suggests a careful and nuanced consideration of these factors as potential answers to the problems affecting SSF. Thus, it is important to: 1) differentiate the types of social capital as potentially relevant for particular outcomes; 2) consider potential external factors affecting social capital; 3) take into consideration that social networks/social capital can change over time; 4) treat social networks/social capital as descriptive, bounded concepts about the social reality (i.e. not normative). Social networks and social capital provide SSF communities with adaptive capacity to cope with change, but ultimately the achievement of long-term sustainability is highly dependent on their levels of vulnerability and to the magnitude of the external perturbations.

Tidskriftsartikel (refereegranskat)abstract
- Tribolium castaneum is a representative of earth’s most numerous eukaryotic order, a powerful model organism for the study of generalized insect development, and also an important pest of stored agricultural products. We describe its genome sequence here. This omnivorous beetle has evolved an ability to interact with a diverse chemical environment as evidenced by large expansions in odorant and gustatory receptors, as well as p450 and other detoxification enzymes. Developmental patterns in Tribolium are more representative of other arthropods than those found in Drosophila, a fact represented in gene content and function. For one, Tribolium has retained more ancestral genes involved in cell-cell communication than Drosophila, and some are expressed in the growth zone crucial for axial elongation in short germ development. Systemic RNAi in T. castaneum appears to use mechanisms distinct from those found in C. elegans, but nevertheless offers similar power for the elucidation of gene function and identification of targets for selective insect control.

Climate impacts on the ocean are making the Sustainable Development Goals a moving target travelling away from us

- Climate change is impacting marine ecosystems and their goods and services in diverse ways, which can directly hinder our ability to achieve the Sustainable Development Goals (SDGs), set out under the 2030 Agenda for Sustainable Development.Through expert elicitation and a literature review, we find that most climate change effects have a wide variety of negative consequences across marine ecosystem services, though most studies have highlighted impacts from warming and consequences of marine species.Climate change is expected to negatively influence marine ecosystem services through global stressors—such as ocean warming and acidification—but also by amplifying local and regional stressors such as freshwater runoff and pollution load.Experts indicated that all SDGs would be overwhelmingly negatively affected by these climate impacts on marine ecosystem services, with eliminating hunger being among the most directly negatively affected SDG.Despite these challenges, the SDGs aiming to transform our consumption and production practices and develop clean energy systems are found to be least affected by marine climate impacts. These findings represent a strategic point of entry for countries to achieve sustainable development, given that these two goals are relatively robust to climate impacts and that they are important pre-requisite for other SDGs.Our results suggest that climate change impacts on marine ecosystems are set to make the SDGs a moving target travelling away from us. Effective and urgent action towards sustainable development, including mitigating and adapting to climate impacts on marine systems are important to achieve the SDGs, but the longer this action stalls the more distant these goals will become.
