Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, EarlyView.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

Conservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

The hole in the doughnut: Formalizing and testing a key model of degrowth

Contemporary Economic Policy, EarlyView.
Abstract Degrowth scholars often claim that capitalism generates social and ecological imbalances, as captured by Kate Raworth's leading doughnut model. We formalize this model using social and environmental indices and measure imbalances using their coefficient of variation.

Unified Assembly Condition of Evenly and Non-evenly Spaced Planet Gear

Jixie chuandong, 2020
A unified assembly condition formula is derived for planet gears，taking the NW planetary gear train as an example. Firstly，the minimum non-zero misalignment angle between the two teeth of compound planetary gears is determined.
