Patterns of abundance across geographical ranges as a predictor for responses to climate change: Evidence from UK rocky shores
Read this new, Open Access paper in the journal Diversity and Distributions , in which Nova Mieszkowska is the MBA's Principal Investigator.
Understanding patterns in the abundance of species across thermal ranges can give useful insights into the potential impacts of climate change. The abundant‐centre hypothesis suggests that species will reach peak abundance at the centre of their thermal range where conditions are optimal, but evidence in support of this hypothesis is mixed and limited in geographical and taxonomic scope. We tested the applicability of the abundant‐centre hypothesis across a range of intertidal organisms using a large, citizen science‐generated data set.

Earlier this month, the Joint Nature Conservation Committee (JNCC) released their report ‘ Developing the evidence-base to support climate-smart decision-making on MPAs ’ on the finding of the Defra-funded Climate-smart MPAS project
JNCC was commissioned by Defra to develop the evidence base around climate-smart decision-making in Marine Protected Areas (MPAs). The first phase of this work was a project analysing the role of MPAs and their protected features in mitigating the impacts of climate change (e.g. through the sequestration of carbon).
Working with the Marine Biological Association (MBA), the sensitivity of high priority MPA protected features to climate-related pressures was assessed and presented on the Marine Life Information Network (MarLIN) website. As part of this project, sensitivity assessments were undertaken for 36 high priority biotopes related to...

The MBA's Continuous Plankton Recorder (CPR) Survey featured recently in The Guardian newspaper.
The national news article introduced the CPR as a 'vast marine mission' that has 'allowed scientists to see dramatic patterns in ocean health, across both time and space, building a much clearer picture of how our marine environments are changing'.
Here at the MBA, we are celebrating the continued success of the CPR survey during the Covid-19 era and the collaborative efforts of the CPR Operations team and shipping industry.
The article marks a major milestone for the CPR survey as it clocked up 7 million nautical miles of data collection. This staggering figure equates to nearly 17 round trips to the moon! On the 17th June at 21:55 the MS Norrona ( Smyril Lines ) towed a continuous plankton recorder through this incredible...

Chytrids are widespread, single-cell, microscopic fungi that are important parasites of other organisms and degraders of complex organic matter in aquatic ecosystems. They attach to substrates and feed using filamentous outgrowths called rhizoids. In this study, we show that chytrid rhizoids are remarkably similar to hyphae in multi-cellular fungi, suggesting a linked evolutionary origin. We also show that chytrid rhizoids are highly adaptative, able to change shape in response to variation in substrate availability. Together, our study sheds new light on fungal evolution and the biology of chytrids.
The research, led by Davis Laundon of the Marine Microbial Biogeochemistry research group was published today in Proceedings of The Royal Society B .
MBA Senior Research Fellow Michael Cunliffe said, “This outstanding research from Davis Laundon’s PhD utilises...

A widespread decline in summer abundance of the most nutritious plankton types across the north-east Atlantic continental shelf is affecting animals higher up the food web such as fish, marine mammals, and seabirds, says a new study published today in the journal Global Change Biology .
A change from cloudy, wetter summers to hotter, drought conditions leads to earlier onset and increased stability of the warm surface layer in shelf waters. These conditions lead to persistent sub-optimal conditions for larger omega-3 rich phytoplankton, and favour smaller, less nutritious picophytoplankton, especially the cyanobacterium Synechococcus . This change negatively impacts the success of the copepod community, and propagates throughout the food web. This trend has been observed over the last 60 years.
A new study published today in the journal Global...

" The United Nations Decade on Ecosystem Restoration 2021–2030 was conceived as a means of highlighting the need for greatly increased global cooperation to restore degraded and destroyed ecosystems, contributing to efforts to combat climate change and safeguard biodiversity, food security, and water supply ".
The latest edition of The Marine Biologist is dedicated to the UN decade, and in celebration of this we are making articles from the magazine freely available online. Furthermore, we a launching a new online initiative: ' The Marine Biologist Deep Dive ' (see below), an online Q&A session with authors to discuss the topic of their articles in more detail.
The articles illustrate two very different aspects of marine ecosystem restoration: coral reef restoration and...

New smart-tag technology grant awarded to measure ocean predator physiology and distributions.
A marine scientist at the Marine Biological Association of the UK (MBA) Laboratory in Plymouth, UK, has been awarded a prestigious European Research Council (ERC) Advanced Grant to fund cutting edge research that addresses climate change impacts on threatened ocean predators.
The ERC Advanced awards are funded through the EU and are worth up to €2.5M, enabling established top researchers to explore their most creative, high-risk ideas, and leading to the creation of jobs including scientific and technical support positions.
The grant has been awarded to Professor David Sims, a Senior Research Fellow at the MBA and professor at the University of Southampton, with the aim to understand how large, active predators such as sharks and tuna will be...
