- Wastewater treatment and nitrogen and phosphorus (P) recovery in harvested biomass of two macrophyte species receiving two wastewater loading rates was studied in a free water surface constructed wetland (FWS CW) in Kenya. Half the CWs were planted with Cyperus papyrus and half with Echinochloa pyramidalis. Inlets and outlets water samples were analysed for selected water quality parameters. Macrophytes were harvested at around 7 month intervals on three occasions for determination of biomass, P and N content. Area specific removals of TP, TSS and Nh4+-N were higher in the high-load CWs and in the low-load ones, but the relative removal was lower. For Nh4+-N, there was a significantly higher removal in C. papyrus CWs- Each macrophyte species had similar tissue P content independent of mass load suggesting excess available phosphorus in all CWs, as supported by the low N:P ratios. During a 7 month period, the amount of P stored daily in the green biomass of the macrophytes represented 18-29% and 25-100% of the daily removal of TP and TDP, respectively.

Gastrointestinal dysfunction in patients and mice expressing the autism-associated R451C mutation in neuroligin-3

- Gastrointestinal (GI) problems constitute an important comorbidity in many patients with autism. Multiple mutations in the neuroligin family of synaptic adhesion molecules are implicated in autism, however whether they are expressed and impact GI function via changes in the enteric nervous system is unknown. We report the GI symptoms of two brothers with autism and an R451C mutation in Nlgn3 encoding the synaptic adhesion protein, neuroligin-3. We confirm the presence of an array of synaptic genes in the murine GI tract and investigate the impact of impaired synaptic protein expression in mice carrying the human neuroligin-3 R451C missense mutation (NL3(R451C)). Assessing in vivo gut dysfunction, we report faster small intestinal transit in NL3(R451C) compared to wild-type mice. Using an ex vivo colonic motility assay, we show increased sensitivity to GABA(A) receptor modulation in NL3(R451C) mice, a well-established Central Nervous System (CNS) feature associated with this mutation. We further show increased numbers of small intestine myenteric neurons in NL3(R451C) mice. Although we observed altered sensitivity to GABA(A) receptor modulators in the colon, there was no change in colonic neuronal numbers including the number of GABA-immunoreactive myenteric neurons. We further identified altered fecal microbial communities in NL3(R451C) mice. These results suggest that the R451C mutation affects small intestinal and colonic function and alter neuronal numbers in the small intestine as well as impact fecal microbes. Our findings identify a novel GI phenotype associated with the R451C mutation and highlight NL3(R451C) mice as a useful preclinical model of GI dysfunction in autism. Autism Res 2019, 12: 1043-1056. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary People with autism commonly experience gastrointestinal problems, however the cause is unknown. We report gut symptoms in patients with the autism-associated R451C mutation encoding the neuroligin-3 protein. We show that many of the genes implicated in autism are expressed in mouse gut. The neuroligin-3 R451C mutation alters the enteric nervous system, causes gastrointestinal dysfunction, and disrupts gut microbe populations in mice. Gut dysfunction in autism could be due to mutations that affect neuronal communication.

A global science-policy partnership for progress toward sustainability of oceanic ecosystems and fisheries

Forskningsöversikt (refereegranskat)abstract
- Oceanic ecosystems support livelihoods and supply food for hundreds of millions of people. But these ecosystems are deteriorating rapidly and many of the world's oceanic fisheries are in a precarious condition. In addition to well-known and pressing fishery management issues, economic globalization is connecting fisheries beyond the frontiers of the organizations responsible for their management and climate-associated changes are deeply modifying ecosystems, pushing them toward new states and no return situations. The status quo is not a sustainable option, and improved international governance is urgently needed to address this situation. Our proposition consists of an inclusive global science-policy process combining major improvements to the present governance systems, including new incentives for international cooperation and coordination, with an ambitious scientific program to help anticipate threats and opportunities and integrate complex information regarding long-term issues. It would constitute a major step toward sustainability.

Conceptualizing ecosystem services using social–ecological networks
- 2022

Tidskriftsartikel (refereegranskat)abstract
- Social–ecological networks (SENs) represent the complex relationships between ecological and social systems and are a useful tool for analyzing and managing ecosystem services. However, mainstreaming the application of SENs in ecosystem service research has been hindered by a lack of clarity about how to match research questions to ecosystem service conceptualizations in SEN (i.e., as nodes, links, attributes, or emergent properties). Building from different disciplines, we propose a typology to represent ecosystem service in SENs and identify opportunities and challenges of using SENs in ecosystem service research. Our typology provides guidance for this growing field to improve research design and increase the breadth of questions that can be addressed with SEN to understand human–nature interdependencies in a changing world.

Tracking integrated ecosystem assessments in the ICES network : a social network analysis of the ICES expert groups

- The advice the International Council for the Exploration of the Sea (ICES) provides to its member countries is crucial for the sustainable management of shared marine resources, and the conservation of relevant marine ecosystems. In 2014, ICES made a strategic decision to integrate marine and social sciences in a new type of assessment framework called “integrated ecosystem assessments” (IEA) to deliver advice on societal trade-offs between different policy options. The IEA-focused expert groups formed before and after this period now cover all major ecoregions. To track the progression of IEAs in the ICES network over time, we conducted a social network analysis (SNA) on expert group attendance for the years 2015–2019. The IEA-focused expert groups generally ranked lower in the overall ICES network. Our study shows that some IEA-groups become more connected over time, while others decline. We also evaluated the role of workshops in the ICES network, particularly their role in the development of IEA knowledge. Our study shows that workshops play an important role in ICES network connectivity. The study demonstrates how social network analysis can be used to study an organization such as ICES and determine the effectiveness, or impact, of that organizational function.

Collaboration and individual performance during disaster response
- 2023
-
Ingår i: Global Environmental Change. - : Elsevier. - 0959-3780 .- 1872-9495. ; 82

Tidskriftsartikel (refereegranskat)abstract
- Disasters occurring in the wake of extreme weather events are increasing in frequency and severity due to climate and anthropogenic changes and require urgent responses under uncertain and dynamic conditions. In these situations, multi-agency collaboration becomes integral to an effective response due to the need to coordinate actions across geographical scales, levels of authority and sectors of society. Consequently there is a need for more knowledge on how to enhance the effectiveness of collaborations in response to disasters. In this study we utilize extremely rare and comprehensive data on multi-stakeholder collaboration during the acute phase of two catastrophic wildfires to investigate performance in relation to four collaboration challenges: sharing information, conflict resolution, reaching agreement i.e. mutual understanding and commitment, on goals and workingmethods, and coordinating activities. Our results suggest that agreement between collaborating actors is more important to individual performance than the coordination of activities, and that it is only when agreement exists that the ability to coordinate activities becomes highly important. This study allows, for the first time, insights into the detailed nuances of collaboration among individuals during rapidly evolving disaster situations. Importantly, our analysis suggests that focusing on enhancing agreement in the wake of disasters-and not only on improving coordination-could reduce the devastating effects that disasters have on people and ecosystems.
