Anna is in Oslo this week to meet with Sofia Ferreira and Joël Durant at the Centre for Ecological and Evolutionary Synthesis, University of Oslo. Under Sofia’s SPITFIRE project, we’re exploring match-mismatch effects for larval fish with implications for fisheries production. Anna will also present her work on the biological theory of relativity (more here).
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
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.“
Neuheimer Lab @ Universität Hamburg
On Friday, Anna will be giving an invited seminar at the University of Hamburg’s Institute for Marine Ecosystem and Fishery Science. Anna will be speaking on “The pace of life: Time, temperature and a biological theory of relativity” at 12:00. Read the related preprint over at bioRxiv.

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.

New Article: How coral reef life history strategies shape settlement success
A new article is out today in Frontiers in Marine Science led by Neuheimer Lab alumnus Jennifer Wong-Ala. The study developed and applied a biophysical model of individuals to explore how different life history characteristics (e.g. spawning location & date, pelagic larval duration or PLD) interact with the environment to change settlement success for fishes off west Hawai'i Island. The work identified multiple pathways (including the use of eddies) that can lead to self-recruitment for fish (and potentially invertebrate) communities in the area. The study was a collaboration among Neuheimer, Powell, McManus, and Hixon labs, as well as NOAA's Pacific Island Fisheries Science Center (Gove & Whitney). The pdf can be found here.
Neuheimer Lab @ 2018 Ocean Sciences Meeting, Portland, OR, USA
Neuheimer Lab alumnus Jennifer Wong-Ala (currently at Oregon State University) will be presenting our work on how life history shapes reef fish settlement off Hawai'i Island. The work, a collaboration with NOAA as well as the McManus, Powell and Hixon labs, explores how biophysical factors shape the ability of larval reef fish to make it back to the reef. Jennifer will be presenting in today's (Monday 12 Feb) poster session from 16:00-18:00.
