More info on session descriptions and invited speakers is available here. Hope to see you in Anchorage in May!
Submit an abstract: 2017 ASLO Meeting - Bridging the eco-evolutionary gap
We invite you to submit an abstract to
Session 044 - Bridging the eco-evolutionary gap: Plastic and adaptive responses to climate change
at the 2017 ASLO Aquatic Science Meeting in Honolulu (Hawaii; 26 Feb – 03 Mar).
Abstracts are due 14 October 2016.
Here's a description of the session:
Climate change is affecting ecological processes and biogeochemical cycles of marine environments. Species respond to climate change through both phenotypic plasticity and microevolutionary adaptations. For example, across many trophic levels, species quickly respond to change is by shifting their distribution in space (e.g. population distribution) or time (e.g. reproductive events). However, there are limits to these types of responses, imposed by the presence of the limiting requirements of different critical stages in a species? life history. These limitations are linked to a species? life history strategy, with further response of the species beyond this point moving from phenotypic plasticity to genetic adaptation. There is unfortunately a chasm between phenotypic plasticity and evolutionary adaptations in the literature of marine species response to climate change. In this session we invite studies on species? response to environmental change, using both niche-based (e.g., climate-envelope models) and genetic (e.g., evolutionary models) approaches. Through this theme session we intend to develop awareness among scientists and build capacity to merge these two realities by including more evolutionary thinking in niche-based approaches and more ecological thinking in studies of species evolutionary processes. This understanding is necessary as we develop models to project species adaptability to future climate scenarios.
New Article: Spatial variability in deep-diving toothed whale occurrence in the Ligurian Sea, Mediterranean
A second article from our collaboration with UH’s Marine Mammal Research Program over at the Hawai`i Institute of Marine Biology has been accepted at Deep Sea Research Part I. In the article, we use passive acoustic recordings to explore spatial variability in toothed whale occurrence in the Ligurian Sea, Mediterranean.
Neuheimer Lab @ Aarhus University
Anna is visiting Peter Grønkjær in the Department of Bioscience at Aarhus University (Aarhus, Denmark) for the next two months to collaborate on ongoing research of high latitude fishes.
Neuheimer Lab MSc defence - Congrats Chantel!
On 15 July 2016, lab member Chantel Chang successfully defended her Oceanography MSc thesis entitled "The Influence of Biophysical Factors on the Connectivity of Holoplanktonic Copepods". It was a wonderful celebration of all Chantel's hard work and excellent contributions to our lab and department. Congratulations Chantel!

Neuheimer Lab @ Bayesian Workshop, Colorado State University
Anna is at CSU in Fort Collins, CO this month to attend a NSF-funded (award #: DEB-1145200) Bayesian modelling workshop presented by Drs. Tom Hobbs, Mevin Hooten, Kiona Ogle, and Maria Uriarte. The workshop follows material in Drs. Hobbs and Hooten's 2015 book Bayesian Models: A Statistical Primer for Ecologists.
Congratulations 2016 C-MORE Scholars!
Congratulations to this year's C-MORE Scholars, including our very own Jennifer Wong-Ala! Best of luck in all your future endeavours, Scholars!
Neuheimer Lab @ ICES/PICES 6th Zooplankton Production Symposium
Chantel and Anna are in Bergen this week for the ICES/PICES 6th Zooplankton Production Symposium. Come check out our poster "Can biophysical processes explain copepod connectivity and distribution across the Atlantic Ocean basin?" (#136, Tues. 10 May, 17:45-19:45). A big mahalo (takk!) to PICES for providing Chantel with a grant to support her travel to Norway.
Adult and offspring size paper featured at The Centre for Ocean Life
Our paper (and accompanying data paper) exploring patterns of adult and offspring size in the ocean is featured on the Centre for Ocean Life's website here.
New Article: Adult and offspring size in the ocean data paper
Our data paper, Adult and offspring size in the ocean: A database of size metrics and conversion factors, is posted as an Accepted Article over at Ecology. The database contains adult and offspring size estimates (and associated conversion factors) for marine species covering >17 orders of magnitude in body mass. The work is a collaboration with the Centre for Ocean Life and accompanies our papers:

ME14D-0640: The Influence of Life History Variability on Population Connectivity: Development and Application of a Trait-Based Biophysical Model of Individuals
J. Wong-Ala, A.B. Neuheimer, M. Hixon & B. Powell
Connectivity estimates, which measure the exchange of individuals among populations, are necessary to create effective reserves for marine life. Connectivity can be influenced by a combination of biology (e.g. spawning time) and physics (e.g. currents). In the past a dispersal model was created in an effort to explain connectivity for the highly sought after reef fish Lau‘ipala (Yellow Tang, Zebrasoma flavescens) around Hawai‘i Island using physics alone, but this was shown to be insufficient. Here we created an individual based model (IBM) to describe Lau‘ipala life history and behavior forced with ocean currents and temperature (via coupling to a physical model) to examine biophysical interactions. The IBM allows for tracking of individual fish from spawning to settlement, and individual variability in modeled processes. We first examined the influence of different reproductive (e.g. batch vs. constant spawners), developmental (e.g. pelagic larval duration), and behavioral (e.g. active vs. passive buoyancy control) traits on modeled connectivity estimates for larval reef fish around Hawai‘i Island and compared results to genetic observations of parent-offspring pair distribution. Our model is trait-based which allows individuals to vary in life history strategies enabling mechanistic links between predictions and underlying traits and straightforward applications to other species and sites.
