As access to the Arctic region continues to grow, many land-use issues have become increasingly prominent. The exposure of shorter shipping routes, unresolved maritime boundaries between the bordering states, and most importantly, the plethora of renewable and non-renewable resources in the region have created a strain on international relations between the states bordering the Arctic. Rising global temperatures have created the promise and opportunity of better access to natural resources in the coming years, raising the likelihood of potentially substantial economic gains to the bordering states. However, the current property rights structure in the Arctic, as governed by the United Nations Convention on the Law of the Sea (UNCLOS), dictates that the jurisdiction of each coastal nation state shall not exceed past 200 nautical miles beyond the coastline of each respective state. The goal of this report is to provide an assessment of the basic property rights that govern the Arctic territory in an attempt to illuminate how current and future inefficiencies in natural resource extraction and management can result from a poor property rights structure. The current property rights structure has led to a departure from an efficient allocation of rights and as a result currently operates under an anticommons scenario, while also setting the stage for a tragedy of the commons in the not so distant future. To move away from these sub-optimal outcomes and toward more efficient resource management, open communication, cooperation, and better defined property rights are important components needed to strengthen resource management among Arctic states. Keywords: Arctic land-use and property rights (assessment of); natural resource extraction and management (inefficiencies in); anticommons scenario; tragedy of the commons; Arctic Council; UNCLOS

AbstractPlasmids are autonomous genetic elements that can be exchanged between microorganisms via horizontal gene transfer (HGT). Despite the central role they play in antibiotic resistance and modern biotechnology, our understanding of plasmids’ natural ecology is limited. Recent experiments have shown that plasmids can spread even when they are a burden to the cell, suggesting that natural plasmids may exist as parasites. Here, we use mathematical modeling to explore the ecology of such parasitic plasmids. We first develop models of single plasmids and find that a plasmid’s population dynamics and optimal infection strategy are strongly determined by the plasmid’s HGT mechanism. We then analyze models of co-infecting plasmids and show that parasitic plasmids are prone to a “tragedy of the commons” in which runaway plasmid invasion severely reduces host fitness. We propose that this tragedy of the commons is averted by selection between competing populations and demonstrate this effect in a metapopulation model. We derive predicted distributions of unique plasmid types in genomes—comparison to the distribution of plasmids in a collection of 17,725 genomes supports a model of parasitic plasmids with positive plasmid–plasmid interactions that ameliorate plasmid fitness costs or promote the invasion of new plasmids.
