An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

open access: yesConservation Biology, EarlyView.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

A review of beluga (Delphinapterus leucas) sexual behavior and reproductive physiology leading to conception

open access: yesTheriogenology Wild
This review summarizes the available literature on the knowledge of reproduction in white whales or belugas (Delphinapterus leucas). We discuss reproductive anatomy, physiology, endocrinology, and behavior prior to conception.

Route Fidelity during Marine Megafauna Migration

open access: yesFrontiers in Marine Science, 2017
The conservation and protection of marine megafauna require robust knowledge of where and when animals are located. Yet, our ability to predict animal distributions in space and time remains limited due to difficulties associated with studying elusive ...

Comparative review of entanglement risk assessments for cetacean conservation and management

open access: yesConservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Sizing the White Whale

open access: yes
We propose a computational, convex hull free framework that takes advantage of the combinatorial structure of a zonotope, as for example its symmetry group, to orbitwise generate all canonical representatives of its vertices. We illustrate the proposed framework by generating all the 1 955 230 985 997 140 vertices of the $9$-dimensional White Whale. We

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

open access: yesThe FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

Evidence of spatial structuring of eastern South Pacific humpback whale feeding grounds

open access: yesEndangered Species Research, 2013
The eastern South Pacific humpback whale population winters primarily off Colombia and Ecuador, extending northward to the coasts of Panama and Costa Rica.

Before It Was ‘New’: A Neglected History of Lived Experience–Led Criminal Justice

open access: yesThe Howard Journal of Crime and Justice, EarlyView.
ABSTRACT A growing range of criminal justice initiatives are being shaped and delivered by people with lived experience, including peer mentoring, prisoner councils and policy advocacy roles. While often seen as recent innovations, we reveal a deeper, largely unacknowledged history dating back to at least the 19th century.

Time‐stressed Bar‐tailed Godwits exploit novel prey during migratory fuelling

open access: yesIbis, EarlyView.
Long‐distance migratory birds breeding in the Arctic face challenges as earlier snowmelt shifts the timing of vital resources. To keep up with these advancements, birds will need to modify their migration. Higher fuelling rates during stopover have been identified as a critical mechanism for accelerating migration, but this requires adequate food ...
