Nonlinear responses of ecosystem carbon fluxes to nitrogen deposition in an old-growth boreal forest

Aijun Xing, Enzai Du, Haihua Shen, Longchao Xu, Wim De Vries, Mengying Zhao, Xiuyuan Liu & Jingyun Fang
Nitrogen (N) deposition is known to increase carbon (C) sequestration in N-limited boreal forests. However, the long-term effects of N deposition on ecosystem carbon fluxes have been rarely investigated in old-growth boreal forests. Here we show that decade-long experimental N additions significantly stimulated net primary production (NPP) but the effect decreased with increasing N loads. The effect on soil heterotrophic respiration (Rh) shifted from a stimulation at low-level N additions to an inhibition at higher...

Data from: Chicken gut microbiome members limit the spread of an antimicrobial resistance plasmid in Escherichia coli

Sarah Duxbury, Jesse Alderliesten, Mark Zwart, Arjan Stegeman, Egil Fischer & Arjan De Visser
Plasmid-mediated antimicrobial resistance is a major contributor to the spread of resistance genes within bacterial communities. Successful plasmid spread depends upon a balance between plasmid fitness effects on the host and rates of horizontal transmission. While these key parameters are readily quantified in vitro, the influence of interactions with other microbiome members is largely unknown. Here, we investigated the influence of three genera of lactic acid bacteria (LAB) derived from the chicken gastrointestinal microbiome on...

Functional biogeography of Neotropical moist forests: trait-climate relationships and assembly patterns of tree communities

Bruno Pinho, Marcelo Tabarelli, Cajo Ter Braak, S. J. Wright, Victor Arroyo-Rodriguez, Maíra Benchimol, Bettina Engelbrecht, Simon Pierce, Peter Hietz, Bráulio Santos, Carlos Peres, Sandra Müller, Ian Wright, Frans Bongers, Madelon Lohbeck, Ülo Niinemets, Martijn Slot, Steven Jansen, Davi Jamelli, Renato Augusto Ferreira De Lima, Nathan Swenson, Richard Condit, Jos Barlow, Ferry Slik, Manuel Hernández-Ruedas … & Felipe Melo
Aim: Here we examine the functional profile of regional tree species pools across the latitudinal distribution of Neotropical moist forests, and test trait-climate relationships among local communities. We expected opportunistic strategies (acquisitive traits, small seeds) to be overrepresented in species pools further from the equator due to long-term instability, but also in terms of abundance in local communities in currently wetter, warmer and more seasonal climates. Location: Neotropics. Time period: Recent. Major taxa studied: Trees....

Hydraulic prediction of drought-induced plant dieback and top-kill depends on leaf habit and growth form

Ya-Jun Chen, Brendan Choat, Frank Sterck, Phisamai Maenpuen, Masatoshi Katabuchi, Shu-Bin Zhang, Kyle Tomlinson, Rafael Oliveira, Yong-Jiang Zhang, Kun-Fang Cao & Steven Jansen
Hydraulic failure caused by severe drought contributes to aboveground dieback and whole-plant death. The extent to which dieback or whole-plant death can be predicted by plant hydraulic traits has rarely been tested among species with different leaf habits and/or growth forms. We investigated 19 hydraulic traits in 40 woody species in a tropical savanna and their potential correlations with drought response during an extreme drought event during the El Niño–Southern Oscillation in 2015. Plant hydraulic...

Fast life-histories are associated with larger brain size in killifishes

Will Sowersby, Simon Eckerström-Liedholm, Alexander Kotrschal, Joacim Näslund, Piotr Rowiński, Alejandro Gonzalez-Voyer & Björn Rogell
The high energetic demands associated with the vertebrate brain are proposed to result in a trade-off between the pace of life-history and relative brain size. However, because both life-history and brain size also have a strong relationship with body size, any associations between the pace of life-history and relative brain size may be confounded by coevolution with body size. Studies on systems where contrasts in the pace of life-history occur without concordant contrasts in body...

Dead wood diversity promotes fungal diversity

Shanshan Yang
Dead wood is a source of life as it provides habitat and substrate for a wide range of fungal species. A growing number of studies show an important role of wood quality for fungal diversity, but in most cases for a limited number of wood traits or tree species. In this study, we evaluate how abiotic and biotic factors affect the fungal diversity and composition during dead wood decomposition. For 10 common European tree species,...

Why forest fails to recover after repeated wildfires in Amazonian floodplains? Experimental evidence on tree recruitment limitation

Bernardo Flores & Milena Holmgren
Amazonian floodplain forests are particularly vulnerable to wildfires that spread during extreme droughts, causing large scale forest dieback. After a second wildfire, these forests persist trapped with low tree cover and empty seed banks, yet the mechanisms that could explain this arrested succession remain unknown. Here we use a four-year field experiment to test whether tree recruitment failures in burnt floodplain forests are caused by environmental filtering, limiting early seedling emergence and establishment. We sowed...

ddRAD of Hawaiian Ariamnes spiders

Ellie Armstrong, Benoît Perez-Lamarque, Ke Bi, Leontine Becking, Jun Lim, Tyler Linderoth, Rosemary Gillespie & Henrik Krehenwinkel
The diversification of a host organism can be influenced by both the external environment and its assemblage of microbes. Here, we use a young lineage of spiders, coupled with a chronologically arranged series of volcanic mountains, to determine the evolutionary history of a host and its associated microbial communities, altogether forming the “holobiont”. Using the stick spider Ariamnes waikula (Araneae, Theridiidae) on the island of Hawaiʻi, and outgroup taxa on older islands, we tested whether...

Eighty-four per cent of all Amazonian arboreal plant individuals are useful to humans

Sara D. Coelho, Carolina Levis, Fabrício B. Baccaro, Fernando O. G. Figueiredo, André Pinassi Antunes, Hans Ter Steege, Marielos Peña-Claros, Juliana Schietti & Charles R. Clement
Plants have been used in Amazonian forests for millennia and some of these plants are disproportionally abundant (hyperdominant). At local scales, people generally use the most abundant plants, which may be abundant as the result of management of indigenous peoples and local communities. However, it is unknown whether plant use is also associated with abundance at larger scales. We used the population sizes of 4,454 arboreal species (trees and palms) estimated from 1946 forest plots...

Differences in ontogenetic and diurnal microhabitat selection by sympatric live-bearing fish species with different reproductive modes

Andres Hagmayer, Andrew Furness & Bart Pollux
A pregnancy imposes a heavy reproductive burden on females. Some live-bearing species have evolved reproductive adaptations to reduce this burden, which may influence their ability to utilize specific microhabitats. We investigate whether two such reproductive adaptations, placentation (embryo provisioning via a placenta) and superfetation (the ability to carry multiple broods at various developmental stages), influence microhabitat selection by five sympatric Costa Rican live-bearing fish species (family Poeciliidae). Theory predicts that placentation and superfetation should both...

An Agent Based Model to assess resilience and efficiency of food supply chains

Geerten Hengeveld & George AK van Voorn
This is an Agent Based Model of a generic food chain network consisting of stylized individuals representing producers, traders, and consumers. It is developed to: 1/ to describe the dynamically changing disaggregated flows of crop items between these agents, and 2/ to be able to explicitly consider agent behavior. The agents have implicit personal objectives for trading. Resilience and efficiency are quantified using the ascendency concept by linking these to the fraction of fulfillment of...

Spatial autocorrelation shapes liana distribution better than topography and host tree properties in a subtropical evergreen broadleaved forest in SW China

Bai Xiao-Long, Liu Qi, Mohandass Dharmalingam, Cao Min, Wen Han-Dong, Chen Ya-Jun, Gupta Sunil Kumar, Lin Lu-Xiang & Zhang Jiao-Lin
Lianas are an important component of subtropical forests, but the mechanisms underlying their spatial distribution patterns have received relatively little attention. Here, we selected 12 most abundant liana species, constituting up to 96.9% of the total liana stems, in a 20-ha plot in a subtropical evergreen broadleaved forest at 2,472 – 2,628 m elevation in SW China. Combining data on topography (convexity, slope, aspect, and elevation) and host trees (density and size) of the plot,...

Female reproductive mode shapes allometric scaling of male traits in livebearing fishes (family Poeciliidae)

Andrew Furness, Andres Hagmayer & Bart Pollux
Reproductive mode is predicted to influence the form of sexual selection. The viviparity driven conflict hypothesis posits that a shift from lecithotrophic (yolk-nourished) to matrotrophic (mother-nourished or placental) viviparity drives a shift from pre-copulatory toward post-copulatory sexual selection. In lecithotrophic species, we predict that pre-copulatory sexual selection will manifest as males exhibiting a broad distribution of sizes, and small and large males exhibiting contrasting phenotypes (morphology and coloration); conversely, in matrotrophic species an emphasis on...

Data from: Unravelling hybridization in Phytophthora using phylogenomics and genome size estimation

Kris Van Poucke, Annelies Haegeman, Thomas Goedefroit, Fran Focquet, Leen Leus, Marília Horta Jung, Corina Junker, Miguel Redondo, Claude Husson, Kaloyan Kostov, Aneta Lyubenova, Petya Christova, Anne Chandelier, Slavcho Slavov, Arthur De Cock, Peter Bonants, Sabine Werres, Jonàs Palau, Benoit Marçais, Thomas Jung, Jan Stenlid, Tom Ruttink & Kurt Heungens
The genus Phytophthora comprises many economically and ecologically important plant pathogens. Hybrid species have previously been identified in at least six of the 12 phylogenetic clades. These hybrids can potentially infect a wider host range and display enhanced vigour compared to their progenitors. Phytophthora hybrids therefore pose a serious threat to agriculture as well as to natural ecosystems. Early and correct identification of hybrids is therefore essential for adequate plant protection but this is hampered...

Retention fraction of 15N-labelled deposited ammonium and nitrate in forests

Geshere Abdisa Gurmesa, Ang Wang, Shanlong Li, Shushi Peng, Wim De Vries, Per Gundersen, Philippe Ciais, Oliver L Phillips, Erik Hobbie, Weixing Zhu, Knute Nadelhoffer, Yi Xi, Edith Bai, Tao Sun, Dexiang Chen, Wenjun Zhou, Yiping Zhang, Yingrong Guo, Jiaojun Zhu, Lei Duan, Dejun Li, Keisuke Koba, Enzai Du, Guoyi Zhou, Xingguo Han … & Yunting Fang
The impacts of enhanced nitrogen (N) deposition on global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key reactive N forms and its contribution to forest C sink is unclear. We conducted ecosystem-scale paired 15N-labelling experiments in nine forests across China to quantify N retention...

Plant defence to sequential attack is adapted to prevalent herbivores

Erik H. Poelman, Daan Mertens, Maite Fernández De Bobadilla, Quint Rusman, Janneke Bloem & Jacob C. Douma
Plants have evolved plastic defence strategies to deal with uncertainty of when, by which species and in which order attack by herbivores will take place. However, the responses to current herbivore attack may come with a cost of compromising resistance to other, later arriving herbivores. Due to antagonistic cross-talk between physiological regulation of plant resistance to phloem-feeding and leaf-chewing herbivores, the feeding guild of the initial herbivore is considered to be the primary factor determining...

Plant-phenotypic changes induced by parasitoid ichnoviruses enhance the performance of both unparasitized and parasitized caterpillars

Antonino Cusumano, Serge Urbach, Fabrice Legeai, Marc Ravallec, Marcel Dicke, Erik Poelman & Anne-Nathalie Volkoff
There is increasing awareness that interactions between plants and insects can be mediated by microbial symbionts. Nonetheless, evidence showing that symbionts associated with organisms beyond the second trophic level affect plant-insect interactions are restricted to a few cases belonging to parasitoid-associated bracoviruses. Insect parasitoids harbor a wide array of symbionts which, like bracoviruses, can be injected into their herbivorous hosts to manipulate their physiology and behavior. Yet, the function of these symbionts in plant-based trophic...

Global patterns in bumble bee pollen collection show phylogenetic conservation of diet

Thomas Wood, Guillaume Ghisbain, Pierre Rasmont, David Kleijn, Ivo Raemakers, Christophe Praz, Michael Killewald, Jason Gibbs, Kyle Bobiwash, Mira Boustani, Baptiste Martinet & Denis Michez
1. Bumble bees (Bombus) are a group of eusocial bees with a strongly generalised feeding pattern, collecting pollen from many different botanical families. Though predominantly generalists, some bumble bee species seem to have restricted dietary choices. It is unclear whether restricted diets in bumble bees are inherent or a function of local conditions due to a lack of data for many species across different regions. 2. The objective of this study was to determine whether...

A matter of time: Recovery of plant species diversity in wild plant communities at declining nitrogen deposition

Frank Berendse, Rob Geerts, Wim Elberse, Martijn Bezemer, Paul Goedhart, Wei Xue, Erik Noordijk, Cajo Ter Braak & Hein Korevaar
Aim: High levels of nitrogen deposition have been responsible for important losses of plant species diversity. It is often assumed that reduction of ammonia and nitrogen oxide emissions will result in the recovery of the former biodiversity. In Western Europe N deposition peaked between 1980 and 1988 and declined thereafter. In a 60-year experiment in hay meadows we tested the hypothesis that increasing and declining nitrogen deposition had negative, respectively, positive effects on plant species...
