Fish stocks experiencing high fishing mortality show a tendency to mature earlier and at smaller size, which may have genetic component therefore long-lasting economic biological effects. To date, the effects of such ecoevolutionary dynamics not been empirically investigated. Using 70 y data, we develop bioeconomic model for Northeast Arctic cod compare yield in life-history traits can vary only through phenotypic plasticity with which, addition, changes occur. We find that evolutionary...
The rapid rise in inequality is often seen to go in-hand with resource overuse. Examples include water extraction Pakistan, land degradation Bangladesh, forest harvesting Sub-Saharan Africa and industrial fishing Lake Victoria. While access ecosystem services provided by common pool resources mitigates poverty, exclusive technology wealthy individuals may fuel excessive deplete the resource, thus widening wealth gap. We use a stylised social-ecological model, illustrate how positive feedback...
Real world observations suggest that social norms of cooperation can be effective in overcoming dilemmas such as the joint management a common pool resource—but also they subject to slow erosion and sudden collapse. We show these patterns collapse emerge endogenously model closed community harvesting renewable natural resource which individual agents face temptation overexploit resource, while cooperative norm spreads through via interpersonal relations. analyze under what circumstances...
Do private property rights mitigate overexploitation of common pool resources and, if so, under which circumstances? In this paper, we examine the effects on status marine fisheries by combining data ecological, economic, and institutional characteristics into a panel set, spanning over 50 years, 170 exclusive economic zones, 800 species. To address inherent endogeneity problem policy implementation, employ both difference-in-differences (DiD) instrumental variable (IV) strategy. Results...
There are concerns that increasing anthropogenic stressors can cause catastrophic transitions in ecosystems. Such shifts have large social, economic, and ecological consequences therefore important management implications. A potential mechanism behind these regime is the Allee effect, which describes decline realized per capita growth rate at small population density. With an age-structured model for Atlantic cod, Gadus morhua, we illustrate how interactions between human-induced stressors,...
Overexploitation of a shared resource is frequent phenomenon among groups selfish consumers, known as the 'tragedy commons'. To avoid "self-damage through self-interest", humans may either defend exclusive access to resources, or collectively adopt advanced cooperative behaviour and carefully designed spatial harvesting strategies exploit sustainably. However, why do many non-human species that are neither social nor territorial also appear overexploiting resources? This study shows that,...
The allocation process within environmental markets is frequently a source of contention, marked by lack transparency. Historically, fishing opportunities has been primarily rooted in past catches, practice increasingly scrutinized due to its potential implications for future generations and other societal concerns. Climate change related shifts fish distribution, but also stock recoveries, now occurring after decades overfishing, have brought attention this issue, potentially opening...
The mesopelagic is one of the most biomass-rich marine ecosystems on planet and it contributes to mitigating climate change supports food webs globally. Deep-sea fishing a growing threat for ecosystem, yet, may contribute increasing human nutrition by feeding aquaculture production. Here, we used matched species nutritional data, comprehensive dataset ocean-related international agreements, first, assess potential implications second, evaluate extent governance in policies. We found that...
Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This paper develops a bio-economic model that evaluates HCR adopted 2004 by Joint Norwegian–Russian Fishery Commission to manage world's largest cod stock, Northeast Arctic (NEA). The considered here is biologically economically detailed, first compare performance of stock's...
The Arctic faces high expectations of Blue Growth due to future projections easier access and increased biological productivity. These are, however, often based on global regional climate change largely ignore the complexity social-ecological interactions taking place across different temporal spatial scales. This paper illustrates how such cross-scale at, across, dimensions (e.g., ecological, socioeconomic governance) can affect development fisheries; potentially create uncertainties for...
Significance Wildlife populations in Europe and North America are regulated through hunting, as natural predators still scarce. Therefore, wildlife is a social–ecological system with delicate feedbacks between the social ecological subsystems. Both for population control evolution because of cultural values, it essential to understand how many which animals removed from population. However, question context influences individual hunter’s decision shoot or not an animal has been addressed. We...

Abstract Fisheries are supposed to be for the benefit of society, producing food, providing livelihoods and enabling cultural continuity. Biological productivity goals fish stocks operationalised through Harvest Control Rules (HCRs) central contemporary fisheries management. While policies often state socio‐economic objectives, such as enhancing coastal communities, those rarely, if ever, incorporated into management procedures. The lack articulation social objectives monitoring outcomes...
