Drought history affects plant and microbial C turnover after a subsequent drought event

In this new vodcast, Lucia Fuchslueger presents the findings of her recent study, published in the last issue (September) of Journal of Ecology, and titled ‘Drought history affects grassland plant and microbial carbon turnover during and after a subsequent drought event‘. This study was part of Lucia’s PhD project on the effects of Climate Extremes, particularly of extreme droughts, on mountain grassland carbon and nitrogen cycling, funded by the Austria Science Fund. The video is available below and can also be found on the Journal of Ecology YouTube channel.


PicsLucia Fuchslueger received her PhD from the University of Vienna, supervised by Andreas Richter, and co-supervised by Michael Bahn from the University of Innsbruck. The main focus of her project was to elucidate how single and multiple extreme drought events affect the turnover of recently assimilated C within plants and its allocation to below-ground plant compartments, as well as the availability for the soil microbial community, and potential feedbacks for plants. After her PhD research, Lucia moved from temperate grassland systems to the Amazon forest. She is currently working at the National Institute of Amazonian Research (INPA) in Manaus, Brazil, as part of an international team of researchers studying the effects of elevated CO2 on tropical rainforests (Amazon FACE). Her research focuses on plant-soil interactions, and on microbe mediated processes in soils. Specifically, she is interested in microbial dynamics during litter and organic matter decomposition, the effect of nutrient availability on C sequestration, and the responses to changing environmental conditions.

The Quest for Predicting Plant-Soil Feedback

A new study from the Department of Soil Quality at Wageningen University and the Department of Terrestrial Ecology at Netherlands Institute of Ecology (NIOO-KNAW) gives evidence that plants grow better in soil from other species. Published today in Journal of Ecology, the paper is written by Cortois et al. and is titled ‘Plant-soil feedbacks: role of plant functional group and plant traits. 

Authors Roeland Cortois and Gerlinde De Deyn have described below their inspiration behind the study and the significance of their work in the understanding of plant-soil feedbacks and their role in plant communities.


It all started with a simple question which we asked ourselves several years ago: can plant-soil feedbacks explain overyielding in plant species rich communities? 

First of all we aimed to figure out whether plant-soil feedback (PSF) is actually occurring at a measurable and relevant scale and whether feedback sign (positive, neutral or negative) and strength are predictable from plant traits. Considering the growth versus defense trade-off hypothesis, we expected plant species with more acquisitive traits to build-up more negative feedback, whereas species with conservative traits would build-up more positive feedback with their own soil biota.

Some ESA 2016 afterthoughts on the Era of the Anthropocene, Population Ecology, and Archbold by Rob Salguero-Gómez

The annual meeting of the Ecological Society of America took place a bit over a week ago (Aug 7-12th 2016) in Fort Lauderdale. ESA + Florida + August + no hurricanes in Florida the last 10 years = get ready to get blown away either by an overdue hurricane or by the great science that is typically presented at the ESA. Thanks to the fact that a hurricane last week decided last minute to divert its trajectory away from Ft Lauderdale, we were only blown away by the science… ok, and by a lot of humidity too.

The theme of this year’s conference was “Novel Ecosystems in the Anthropocene”, continuing the legacy that was set at the centennial meeting last year in Baltimore. Ecology has the challenging responsibility of understanding and producing predictions regarding how ecological systems will respond to various interacting drivers, both biotic and abiotic. The emphasis in the last decades has turned to treating humans as a third axes of effects. Along that line of thought, the 2016 meeting was full of keynote talks and symposia that nicely summarized our current understanding of human effects on ecosystems and set goals and directions for our futures research steps. I have followed the work by Jeannine Cavender-Bares for a while now (who hasn’t right?), and I thoroughly enjoyed her New Phytologist lecture “Evolutionary legacies on ecosystems: implications for managing planet Earth in the Anthropocene”.

Reflecting on ESA2016 ‘Novel Ecosystems in the Anthropocene’: Three Ecologists Provide Contrasting Perspectives.

Traveling back from the 2016 Annual Meeting of the Ecological Society of America, I was struck by how well the meeting theme ‘Novel Ecosystems in the Anthropocene’ resonated through the presentations (a second theme was seafood – see below). Not all, but a large number of organized sessions and symposia were organized around the meeting theme such as ‘Rising Novelty in Ecosystems and Climates: Looking to the Past to Understand a No-Analog Future’, ‘Novel Ecosystems and Adaptive Management: Sustainability in the Anthropocene’, and ‘Ecological Novelty in the Anthropocene: Are Novel Communities Novel Ecosystems?’.  I didn’t get to most of these, and my own presentation on weed seedling emergence was clearly off-topic, but the social media buzz was all about the theme. All of this sharpened my thinking and awareness of the topic, and, as I listened to presentations, it became clear that while a full understanding and appreciation of the theme among ecologists is emerging, a consensus on how we can apply knowledge from studying and characterizing modern and past ‘novel ecosystems’ is still unclear. Are novel ecosystems systems unique (i.e., ‘no-analog’) only to the recent human-characterized past (i.e., the Anthropocene), or must they have never existed in the deeper past? Do we characterize novel ecosystems by their species assemblage, functional traits, or ecosystem services (or some combination)? Do we manage for novel ecosystems, or are we to accept that they are characteristic of the current biosphere that we have to ‘live with’? 

Here we present interviews with three ecologists that I ran into at ESA. All are Journal of Ecology Associate Editors so each has a good sense for some of the best research being conducted and published. Charlie Canham and Emily Farrer are also co-authors on a couple of the papers that the British Ecological Society included in a Virtual Issue made available to celebrate the ESA meeting theme. I asked the same set of questions to each, albeit with unique follow-ups, but, as you’ll hear, heard a distinctly different, but informed, take. Clearly, the meeting theme is important and relevant, and it’s very interesting to learn how different ecologists view it.

Winner of the Postdoctoral Excellence Award – ESA Plant Population Ecology

Editor’s note

We are very pleased to announce that Jenni McDonald has been selected to receive the Postdoctoral Excellence Award by the Ecological Society of America’s Plant Population Ecology section for her Journal of Ecology paper, “Transients drive the demographic dynamics of plant populations in variable environments.” This paper was part of a BES cross-journal Special Feature “Demography Beyond the Population” comprising 21 papers on this important topic. Congratulations Jenni!

David Gibson
Executive Editor, Journal of Ecology


Jenni.pngJenni McDonald is an early career researcher currently two years into her first postdoctoral research position at the University of Exeter. Her research applies comparative demographic approaches to explore the evolution of life histories. Using COMPADRE, a global database of plant demographic models, coupled with simulated life histories, she is exploring the demographic buffering hypothesis, a theory that predicts traits that have a large influence on fitness are stabilized against environmental change by buffering that trait. Her exploration of stochastic population dynamics in combination with the strong transient research background of colleagues (past and present) at the University of Exeter led to the research topic of the paper published in Journal of Ecology, which highlights the importance of transients in variable environments.


Transients in variable environments

The natural world is rarely constant. Consequently, studying the dynamics of wild plant populations in variable environments is of particular significance to ecologists seeking to understand life history evolution, and has major implications for management and conservation.

Harper Review 2016 – meet the author

This year wHarper review covere published the first of our annual Harper Review series. The series is named after past BES President and Journal of Ecology Editorial Board member, the late John L. Harper CBE FRS and is designed to be thought provoking, authoritative and of broad interest to the ecological community.

Our inaugural review was written by Yvonne Buckley from Trinity College, Dublin and Jane Catford from the University of Southampton and is titled  Does the biogeographic origin of species matter? Ecological effects of native and non-native species and the use of origin to guide management.

We asked Yvonne, who is one of journal’s Associate Editors, to tell us a bit about the review and her research.

        How did you feel about being asked to write our first Harper Review?

Reading Harper’s book “Population Biology of Plants” as an undergraduate sparked my interest in population ecology so it was a real honour to be asked to write the inaugural Harper Review for Journal of Ecology. I had been thinking about writing that paper some time ago but other projects kept getting in the way, the review deadline was great motivation to finally sit down and write it! My co-author Jane Catford and I had been working on a paper on the different demographic dimensions of species invasiveness (also recently published in Journal of Ecology) so we decided to work on the Harper review together as well.

Press Release: The oceans are full of barriers for small organisms

A new study from the Center for Macroecology, Evolution and Climate at the University of Copenhagen, published in Journal of Ecology today, shows that small changes in ocean salinity and temperature can significantly affect the distribution and diversity of phytoplankton.

The paper was written by Mousing et al. and is titled; Evidence of small-scale spatial structuring of phytoplankton alpha- and beta-diversity in the open ocean.

Read the full press release from the University of Copenhagen below.


The oceans are full of barriers for small organisms

Subtle and short-lived differences in ocean salinity or temperature function as physical barriers for phytoplankton, and result in a patchy distribution of the oceans’ most important food resource. The new research from the Center for Macroecology, Evolution and Climate at the University of Copenhagen may help explain the large biodiversity in the sea.

No functional redundancy in freshwater bacterial community

New lay summary wrote by Manuel Delgado-Baquerizo about his paper”Lack of functional redundancy in the relationship between microbial diversity and ecosystem functioning” published in the last issue (July) of Journal of Ecology. Happy reading! 


The shape of the relationship between microbial diversity and ecosystem function (BEF) remains unclear, which limits our capacity to assess the impact of microbial diversity depletion on key ecosystem functions for human well-being, such as CO2 respiratory fluxes and toxin degradation. This knowledge is, moreover, key to predicting ecosystem functions under changing environment and formulating sustainable natural resource management and conservation policies. Here we conducted three independent microcosm experiments to assess the shape of the bacterial BEF relationship in multiple freshwater ecosystems from Australia and United Kingdom.

Our results provide solid evidence that unlike the positive but decelerating BEF relationship observed most frequently in plants and animals, most evaluated functional measurements were related to bacterial diversity in a non-redundant fashion (e.g. exponentially and/or linearly). Reduced bacterial diversity, even after accounting for biomass, caused a decrease in broad (i.e., CO2 respiratory fluxes: conducted by many microbial communities) and specialized (toxin degradation: conducted by few microbial communities) functions in all cases.

Altogether, our results indicate that any loss of freshwater bacterial diversity can disproportionately promote high losses in ecosystem functioning; thus the consequences of declining microbial diversity on ecosystem functioning and human welfare have likely been considerably underestimated.
