Accelerating discoveries at DIII-D with the Integrated Research Infrastructure

T. Bechtel Amara, S. P. Smith, Z. Xing, S. S. Denk et autres

DIII-D research is being accelerated by leveraging high performance computing (HPC) and data resources available through the National Energy Research Scientific Computing Center (NERSC) Superfacility initiative. As part of this initiative, a high-resolution, fully automated, whole discharge kinetic equilibrium reconstruction workflow was …

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

N. J. C. Tyler, R. A. E. Fosbury, David G. Hazlerigg, Christopher Hogg

Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this paper, …

Microanatomy of incremental growth lines in dental tissues in reindeer Rangifer tarandus

A. Boyde, N. J. C. Tyler

Counting growth layers in dentine and/or secondary cementum is widely used for age determination in wild mammals but the underlying seasonal changes in the structure and degree of mineralisation of dental tissue have not been well characterised. We embedded first (m1) and …

Weak coupling between energetic status and the timing of reproduction in an Arctic ungulate

N. J. C. Tyler, Eric Post, David G. Hazlerigg

Bioenergetic constraints are the ultimate determinant of the timing of reproduction, and seasonal breeding is consequently a widely observed trait. Consistent with this, attention has focused on plasticity in reproductive phenology conceptualized as a response to concomitant advances in the phenology of …

Cross-Facility Workflows: Case Studies with Active Experiments

N. J. C. Tyler, R. A. Knop, Deborah Bard, P. Nugent

Experimental and observational science pipelines are increasingly turning to supercomputing resources to handle their large-scale data analysis. Many of these pipelines serve experiments that are running 24/7, and must shutdown or find alternatives for their real-time data analysis during outages. Workflows from …

The Shrinking Resource Base of Pastoralism: Saami Reindeer Husbandry in a Climate of Change

N. J. C. Tyler, Inger Hanssen‐Bauer, Eirik J. Førland, Christian Nellemann

The productive performance of large ungulates in extensive pastoral grazing systems is modulated simultaneously by the effects of climate change and human intervention independent of climate change. The latter includes the expansion of private, civil and military activity and infrastructure and the …

Animal responses to environmental variation: physiological mechanisms in ecological models of performance in deer (Cervidae)

N. J. C. Tyler, Pablo Gregorini, Katherine L. Parker, David G. Hazlerigg

Context Proper assessment of the consequences of environmental variation on animals depends on our ability to predict how they will perform under different circumstances. This requires two kinds of information. We need to know which environmental factors influence animal performance and their …
