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.“
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.
The call for abstracts for the Nordic Remote Sensing Conference 2019 is now open. Here are the details:
Nordic Remote Sensing Conference 2019 (NoRSC’19): Data Acquisition, Algorithms and Applications
Dates: 17-19 September 2019
NoRSC’19 aims to bring together researchers, in both academia and industry, involved in all aspects of remote sensing research - from data acquisition, processing and analysis to applications in a variety of fields. The conference will also serve as a forum for networking to promote collaborative projects in, and with, the Nordic countries.
We cordially invite you to submit abstracts to be considered for a poster or an oral presentation at NoRSC’19. Please find attached the call for abstracts (NoRSC19_Call_for_Abstracts.pdf). The deadline for abstracts is 15th April 2019.
Please circulate this to your colleagues, particularly those with research interests in the Nordic and Arctic countries. Printable poster available here.
We look forward to seeing you in Aarhus in September!
Whether you’re preparing for your qualifying/comprehensive exams, PhD defence or other life challenge, learning to get out of your own way is half the task. Find tips for getting out of your own way here.
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.
and the second on biophysical factors shaping ocean-wide zooplankton connectivity:
Hope to see you there!
In collaboration between UH's SOEST, Aarhus University's AIAS, & DTU Aqua, a new open-access article exploring fish life history timing was published today in Science Advances. The study develops new thermal metrics to find evidence that the reproductive (spawning) timing of Atlantic cod is adapted to allow their young to match the seasonal occurrence of their food.
Tomorrow (30 April) the Department of Oceanography at UH's School of Ocean and Earth Science and Technology (SOEST) is holding its 6th annual Conference of Biological Oceanography Graduate Students (CBOGS). This student-run event will showcase current student research in biological oceanography at SOEST.
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 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.
In collaboration with UH’s Marine Mammal Research Program and led by Dr. Giacomo Giorli (currently at New Zealand's National Institute of Water and Atmospheric Research), an article exploring the deep-sea scattering layer via sonar was published this month in Progress in Oceanography. In the study, we use a Dual-frequency IDentification SONar (DIDSON) to characterize abundance and size of animals in the deep-sea scattering layer off the coast of Hawai'i Island. Read more here.
Anna was awarded an AIAS-COFUND Fellowship and has begun tenure this month at the Aarhus Institute of Advanced Studies in Denmark. The interdisciplinary institute is housed at Aarhus University where Anna's project will focus on developing and applying new mechanistic modelling tools describing controls on larval fish timing and how timing influences the propagation of climate effects through ecosystems.
The Neuheimer Lab is in Kona, Hawai’i this week to present research at the Symposium on West Hawai’i‘s Marine Ecosystem: Bridging the Gap Between Science and Management. Our presentation - a collaboration among those at UH Mānoa (Wong-Ala, Neuheimer, Comfort, McManus, Hixon, Powell) and NOAA (Gove) & JIMAR (Whitney) - explores how life history traits interact with physical forcing to vary reef fish settlement probability for populations on Hawai’i Island’s west coast.
On 03 November 2017, lab member Marie Ferguson successfully defended her Oceanography MSc thesis entitled "Explaining spatial variation in coral size structure in American Samoa". Congratulations Marie on all your hard work and the end product - a clear and comprehensive contribution to the field. A big thank you to Marie's committee - Drs. Mark Merrifield, Tom Oliver and Dione Swanson.
