Bottom‐Up Interactions in State‐Space Age‐Structured Models Using Mass‐Balance Dynamics

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Age‐structured models are used worldwide to regulate fisheries. These models typically ignore top‐down interactions (predation affecting natural mortality) and bottom‐up interactions (consumption affecting individual growth, reproduction, or survival), whereas multispecies catch‐at‐age models often incorporate top‐down but not bottom‐up ...

Helping to Build Stock Assessment Capacity in Australia: A Case Study

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Fisheries stock assessment capacity faces resource constraints in many countries, including limited personnel, high workloads, and restricted funding. Stock assessment scientists often operate under short timelines, with outcomes that can influence livelihoods and receive public scrutiny.

Unilateral Action on Climate Change and the Moral Obligation to Take Leadership

open access: yesJournal of Social Philosophy, EarlyView.
ABSTRACT We claim that a moral obligation to take climate leadership by means of unilateral mitigation depends on the existence of a plausible follow‐the‐leader mechanism whereby unilateral mitigation by some increases the probability of sufficient mitigation by others to avert catastrophic climate impacts.

Expelled by the Antarctic ice: Evolutionary history of the tribe Cunonieae (Cunoniaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Multiple fossil calibration points reveal recent radiations and biogeographical history of the Cunonieae tribe. The most densely sampled phylogeny allowed to infer Antarctica and Patagonia as areas of origin, confirming the reestablishment of Pterophylla and revealing the northward movement of Weinmannia into the tropical Andes. Conflicting plastid and

Multimodel Analysis of the Atmospheric Response to Antarctic Sea Ice Loss at Quadrupled CO2

open access: yesGeophysical Research Letters, 2019
Antarctic sea ice cover is projected to significantly decrease by the end of the twenty‐first century if greenhouse gas concentrations continue to rise, with potential consequences for Southern Hemisphere weather and climate.

Antarctic sea ice increase consistent with intrinsic variability of the Amundsen Sea Low

open access: yesClimate Dynamics, 2016
We investigate the relationship between atmospheric circulation variability and the recent trends in Antarctic sea ice extent (SIE) using Coupled Model Intercomparison Project Phase 5 (CMIP5) atmospheric data, ECMWF Interim reanalysis fields and passive ...
