Join us in Denmark - 2 year postdoc position available!

There is a 2-year postdoctoral position available in the lab! Come explore your research interests related to seasonal timing of zooplankton and/or fish, e.g.:

  • Explaining variability in migration, spawning, settlement and/or larval timing

  • Exploring variability in timing controls across trophic levels

  • Exploring implications of timing variability for population abundance, persistence, distribution and/or connectivity

Our group strives to provide a safe, equitable, inclusive, and inspiring research environment. Without a diversity of skills and experiences, the scientific community is unable to identify and solve complex problems. In keeping with AU goals, we welcome members irrespective of race, religion, gender identification, sexual orientation, age, or disability status and appreciate diverse perspectives. A core value of our group is research integrity (including honesty and transparency) and we act in accordance with the Policy for Research Integrity, Freedom of Research and Responsible Conduct of Research at Aarhus University.

Deadline to apply: 30 October 2020.

New article: Evidence for long-term seamount-induced chlorophyll enhancements

In an article published today in Scientific Reports, we identify the probability and magnitude of chlorophyll enhancements around seamounts. Our study shows seamount-induced chlorophyll enhancements (SICE) are most often associated with shallow (<100 m), low-latitude seamounts. SICE seamounts show chlorophyll enhancements of up to 56% relative to open-ocean waters and are associated with higher fisheries catch relative to non-SICE seamounts.

New Article: Match-mismatch dynamics in the Norwegian-Barents Sea system

Published this month in Marine Ecology Progress Series, we develop and apply a new match-mismatch metric to estimate the spatio-temporal overlap between Northeast Arctic cod and their prey in the Norwegian-Barents Sea. We show the new overlap metric can explain up to 29% of cod recruitment at age 3 years.

New Article: Characterizing sources of mortality in fish early life stages

In a Fish and Fisheries publication earlier this year, we present a method of identifying sources of mortality for larval and juvenile fish from common survey observations (abundance and size).  We apply the method – a statistical state-space model – to identify vulnerable life stages (and important sources of mortality) for six economically and ecologically important fish populations.  Our results identify size-dependent survival and highlight habitat transitions (pelagic to demersal) as important mechanisms influencing fish recruitment. 

The work is a collaboration including those from the University of Oslo, National Oceanic and Atmospheric Administration, Polar Research Institute of Marine Fisheries and Oceanography, Institute of Marine Research, Oregon State University, University of Hawaii at Mānoa, and Aarhus University.  The collaboration arose from the NAMOR workshops organized by J. Durant with funds from the Research Council of Norway. An open-access pdf is available here.

Neuheimer Lab 2.0 - Moving to Aarhus University, Denmark

Screen Shot 2019-10-15 at 3.40.30 PM.png

After 6 happy and productive years at UHM’s Department of Oceanography, the Neuheimer Lab will be moving to Aarhus University (AU) in Aarhus, Denmark beginning 01 February 2020. I am very excited to be joining the dynamic group in Aquatic Biology at AU’s Department of Bioscience. Student and postdoctoral opportunities associated with the move will be announced shortly.

I very much appreciate having had the opportunity to contribute our research and teaching efforts to the dynamic and supportive group in Oceanography at UHM (and the greater SOEST community). I look forward to continuing our collaborations moving forward.

bioRxiv Preprint: The Biological Theory of Relativity

In April, Anna posted a new preprint on bioRxiv discussing “The pace of life: Time, temperature and a biological theory of relativity”. Check out the html file in the supplementary for embedded animations.

“For living things, time proceeds relative to body temperature. In this contribution, I describe the biochemical underpinnings of this “biological time” and formalize the Biological Theory of Relativity (BTR). Paralleling Einstein’s Special Theory of Relativity, the BTR describes how time progresses across temporal frames of reference, contrasting temperature-scaled biological time with our more familiar (and constant) “calendar” time measures. By characterizing the relationship between these two time frames, the BTR allows us to position observed biological variability on a relevant time-scale. In so doing, we are better able to explain observed variation (both temperature-dependent and -independent), make predictions about the timing of biological phenomena, and even manipulate the biological world around us. The BTR presents a theoretical framework to direct future work regarding an entire landscape of fundamental biological questions across space, time and species.“

New Article: Fish and invertebrate connectivity around Moloka‘i, Hawai‘i

With co-authors in the ToBo lab, our study (published in PeerJ) modelled connectivity patterns for 11 fish and invertebrate species around Moloka‘i, Hawai‘i. We used a graph-theoretic approach to visualize our connectivity predictions and included analysis of the role of the Kalaupapa National Historical Park in shaping population connectivity around the island.

The work is a collaboration between UH (HIMB & Oceanography) and Aarhus University (AIAS) with support from the US National Park Service, Aarhus University Research Foundation and the European Union’s Seventh Framework Programme.
