Conditions for a second wave of COVID-19 due to interactions between disease dynamics and social processes

Abstract In May 2020, many jurisdictions around the world began lifting physical distancing restrictions against spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), giving rise to concerns about a possible second wave disease 2019 (COVID-19). These were imposed as collective population response presence COVID-19 in communities. However, is also their socio-economic impacts, and expected increase cases, turn. This suggests that pandemic exemplifies coupled behaviour-disease system. Here we develop minimal mathematical model interaction between social support for school workplace closure transmission dynamics SARS-CoV-2. We find occurs across broad range plausible input parameters, on account instabilities generated by interactions. conclude waves COVID-19–should they materialize–can be interpreted outcomes nonlinear interactions behaviour.

Discovery and quantification of anaerobic nitrogen metabolisms among oxygenated tropical Cuban stony corals

The ISME Journal, Journal Year: 2020, Volume and Issue: 15(4), P. 1222 - 1235

Published: Dec. 20, 2020

Coral reef health depends on an intricate relationship among the coral animal, photosynthetic algae, and a complex microbial community. The holobiont can impact nutrient balance of their hosts amid otherwise oligotrophic environment, including by cycling physiologically important nitrogen compounds. Here we use 15N-tracer experiments to produce first simultaneous measurements ammonium oxidation, nitrate reduction, nitrous oxide (N2O) production five iconic species reef-building corals (Acropora palmata, Diploria labyrinthiformis, Orbicella faveolata, Porites astreoides, porites) in highly protected Jardines de la Reina reefs Cuba. Nitrate reduction is present most species, but oxidation low potentially due photoinhibition assimilatory competition. Coral-associated rates N2O indicate widespread potential for denitrification, especially D. at ~1 nmol cm-2 d-1. In contrast, A. palmata displays minimal active metabolism. Enhanced are observed coincident with dark net respiration periods. Genomes bacterial cultures isolated from multiple confirm that microorganisms ability respire anaerobically either dinitrogen gas or exist within holobiont. This confirmation anaerobic metabolisms coral-associated sheds new light productivity.

The hitchhiker's guide to generic ecological-economic modelling of land-use-based biodiversity conservation policies

Ecological Modelling, Journal Year: 2022, Volume and Issue: 465, P. 109861 - 109861

Biodiversity loss is a result of interacting ecological and economic factors, it must be addressed through an analysis biodiversity conservation policies. Ecological-economic modelling helpful approach to this analysis, but also challenging since modellers often have specific disciplinary background tend misrepresent either the or aspects. Here, we introduce some most important concepts from both disciplines, two cultures differ between present integrated, consistent guide all steps generic ecological-economic modelling, such as formulation research question, development conceptual model, model parametrisation interpretation results. Although focus on models aimed at general understanding causes remedies for loss, guidance provided here may help in more problems. This intersection three disciplines: ecology, economics mathematical addresses readers who knowledge least one these disciplines want learn about others build analyse models. Compared textbooks, focuses practice rather than lengthy explanations theoretical concepts. We attempt demonstrate that does not require magical powers instead manageable exercise.

External fishing effort regulates positive effects of no-take marine protected areas

Biological Conservation, Journal Year: 2022, Volume and Issue: 269, P. 109546 - 109546

Marine protected areas (MPAs) have been established across the globe to mitigate effects of multiple stressors on marine communities. In many locations, MPAs generated positive fish communities, but impacts fishing pressure—the primary stressor seek manage—have not well investigated. We examined changes in biomass inside and outside no-take over 14 years central California, USA. Using data from community-based science program, California Collaborative Fisheries Research Program, we tested which environmental human-induced most influence strength MPA responses. While temperature productivity were included best fit model, found that fine-scale effort data, following reserve implementation, explained spatial variation community responses MPAs. Specifically, differences between sites open larger for reserves near heavily fished locations these exhibited highest rate change biomass, indicating strong exploited As continue be used as a prominent conservation strategy coastal systems, managers should consider both suite (socio-ecological interactions) conditions may alter success establish long-term monitoring programs fully assess functionality into future.

Multiple social network influences can generate unexpected environmental outcomes

Scientific Reports, Journal Year: 2021, Volume and Issue: 11(1)

Published: May 7, 2021

Understanding the function of social networks can make a critical contribution to achieving desirable environmental outcomes. Social-ecological systems are complex, adaptive in which decision makers adapt changing and ecological context. However, it remains unclear how multiple influences interact with feedbacks generate Based on national-scale survey data social-ecological agent-based model context voluntary private land conservation, our results suggest that operate synergistically or antagonistically, thereby enabling behaviors spread by two more mechanisms amplify each other's effects. Furthermore, information through may indirectly affect respond isolated individuals change. The interplay can, therefore, explain success failure conservation outcomes emerging from collective behavior. To understand capacity influence outcomes, must not be seen as 'closed systems'; rather, interventions depend between environment different components system.

Preparing for and managing crown-of-thorns starfish outbreaks on reefs under threat from interacting anthropogenic stressors

Ecological Modelling, Journal Year: 2023, Volume and Issue: 484, P. 110443 - 110443

Published: July 18, 2023

Crown-of-thorns starfish (CoTS) outbreaks rank among the greatest threats to coral throughout Indo-Pacific. In future, reefs already stressed by CoTS will be further burdened overfishing and nutrient loading. How much these two factors exacerbate outbreak severity is still uncertain. Furthermore, management literature has focused on Great Barrier Reef, whereas damage rising across Here, we use a metacommunity model simulate in areas with high growing levels of fishing pressure offshore input.

Community engagement has been identified as a key component for successful conservation efforts. According to community members, stakeholders, and coral reef restoration practitioners in the Seaflower Marine Protected Area (MPA), most effective way engage communities is by building local capacity. We used mixed‐methods approach including interviews, strengths, weaknesses, opportunities, threats analysis, surveys assess strategies employed MPA involve motivations possible barriers that hinder engagement. The residing demonstrated awareness of importance reefs their role livelihoods. They main challenges social dysfunctionality, administrative barriers, environmental threats, along with lack opportunities participate restoration. Our findings trust, promoting equity, transparency, accountability, fostering collaboration, improving communication essential overcoming these challenges. Empowering through capacity‐building initiatives such educational programs, economic incentives, equity inclusion measures, formal certifications, leadership would enhance support MPA. In addition capacity, our research need strategic planning, budgeting, policies enhancing efforts
