Is free trade good for renewable resources? Brander and Taylor redux
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract This paper generalizes the original Brander and Taylor model of open‐access renewable resource use and trade to address three common critiques. First, I introduce heterogeneity across agents in harvesting productivity to smooth out the model's extreme specialization patterns while maintaining its Ricardian structure and tractability. Second, I

EvolvED: Evolutionary Embeddings to Understand the Generation Process of Diffusion Models
Computer Graphics Forum, EarlyView.EvolvED visualises how diffusion models generate images by embedding intermediate outputs to preserve semantics and evolutionary structure. It supports analysis via (a) user‐defined goals and prompts, (b) sampling intermediate images, (c) extracting relevant features, and (d) visualising them in structured radial and rectilinear layouts for ...

Relation between red muscle volume and buoyancy of several deep-water sharks
, 2018 In opposite with fishes, sharks do not possess swimbladder. Their buoyancy is provided by two features: (i) their liver which is large and rich in low density oil (hydrostatic lift) (ii) the shape of their body and fins which provide a resistive force of

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Estimating the total mortality of seabirds following a marine heat wave
Conservation Biology, EarlyView.Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.
