Data from: Experimental inhibition of a key cellular antioxidant affects vocal communication

Simone Messina, Marcel Eens, Giulia Casasole, Hamada AbdElgawad, Han Asard, Rianne Pinxten & David Costantini
1.There is substantial interest of evolutionary ecologists in the proximate mechanisms that modulate vocal communication. In recent times, there has been growing interest in the role of oxidative stress as a mediator of avian song expression. 2.Here we tested whether the experimental inhibition of the synthesis of a key cellular antioxidant (glutathione) reduces song rate metrics of male European starlings (Sturnus vulgaris). We measured the effect of our treatment on total song rate and on...

Data from: Restoration of endangered fen communities: the ambiguity of iron-phosphorus binding and phosphorus limitation

Willem-Jan Emsens, Camiel J.S. Aggenbach, Alfons J.P. Smolders, Dominik Zak, Ruurd Van Diggelen, C.J.S. Aggenbach, A.J.P. Smolders & W.-J. Emsens
1.Low phosphorus (P) availability limits plant biomass production in fens, which is a prerequisite for the persistence of many endangered plant species. We hypothesized that P limitation is linked to soil iron (Fe) content and soil Fe:P ratios as iron compounds provide binding sites for dissolved P, presumably reducing P availability to plants. 2.We sampled 30 fens in a trans-European field survey to determine how soil Fe pools relate to pools of P and Fe-bound...

Data from: How environmental conditions shape the chemical signal design of lizards

Simon Baeckens, José Martín, Roberto García-Roa, Panayiotis Pafilis, Katleen Huyghe & Raoul Van Damme
1. The signals that animals use to communicate often differ considerably among species. Part of this variation in signal design may derive from differential natural selection on signal efficacy; the ability of the signal to travel efficiently through the environment and attract the receiver’s attention. For the visual and acoustic modalities, the effect of the physical environment on signal efficacy is a well-studied selective force. Still, very little is known on its impact on the...

Data from: Patterns and drivers of biodiversity-stability relationships under climate extremes

Hans J. De Boeck, Juliette M. G. Bloor, Juergen Kreyling, Johannes C. G. Ransijn, Ivan Nijs, Anke Jentsch & Michaela Zeiter
Interactions between biodiversity loss and climate change present significant challenges for research, policy and management of ecosystems. Evidence suggests that high species diversity tends to increase plant community stability under interannual climate fluctuations and mild dry and wet events, but the overall pattern of diversity–stability relationships under climate extremes is unclear. We comprehensively review results from observational and experimental studies to assess the importance of diversity effects for ecosystem function under climate extremes. Both the...

Data from: Response of bats to light with different spectra: light-shy and agile bat presence is affected by white and green, but not red light

Kamiel Spoelstra, Roy H. A. Van Grunsven, Jip J. C. Ramakers, Kim B. Ferguson, Thomas Raap, Maurice Donners, Elmar M. Veenendaal & Marcel E. Visser
Artificial light at night has shown a remarkable increase over the past decades. Effects are reported for many species groups, and include changes in presence, behaviour, physiology and life-history traits. Among these, bats are strongly affected, and how bat species react to light is likely to vary with light colour. Different spectra may therefore be applied to reduce negative impacts. We used a unique set-up of eight field sites to study the response of bats...

Data from: Microclimate variability in alpine ecosystems as stepping stones for non-native plant establishment above their current elevational limit

Jonas J. Lembrechts, Jonathan Lenoir, Martin A. Nuñez, Aníbal Pauchard, Charly Geron, Gilles Bussé, Ann Milbau & Ivan Nijs
Alpine environments are currently relatively free from non-native plant species, although their presence and abundance have recently been on the rise. It is however still unclear whether the observed low invasion levels in these areas are due to an inherent resistance of the alpine zone to invasions or whether an exponential increase in invasion is just a matter of time. Using a seed-addition experiment on north- and south-facing slopes (cf. microclimatic gradient) on two mountains...

Data from: Sound attenuation in the ear of domestic chickens (Gallus gallus domesticus) as a result of beak opening

Pieter G. G. Muyshondt, Raf Claes, Peter Aerts & Joris J. J. Dirckx
Because the quadrate and the eardrum are connected, the hypothesis was tested that birds attenuate the transmission of sound through their ears by opening the bill, which potentially serves as an additional protective mechanism for self-generated vocalizations. In domestic chickens, it was examined if a difference exists between hens and roosters, given the difference in vocalization capacity between the sexes. To test the hypothesis, vibrations of the columellar footplate were measured ex vivo with laser...

Data from: Floaters may buffer the extinction risk of small populations: an empirical assessment

Hugo Robles & Carlos Ciudad
The high extinction risk of small populations is commonly explained by reductions in fecundity and breeder survival associated with demographic and environmental stochasticity. However, ecological theory suggests that population extinctions may also arise from reductions in the number of floaters able to replace the lost breeders. This can be particularly plausible under harsh fragmentation scenarios, where species must survive as small populations subjected to severe effects of stochasticity. Using a woodpecker study in fragmented habitats...

Data from: Carbon debt of Conservation Reserve Program (CRP) grasslands converted to bioenergy production

Ilya Gelfand, Terenzio Zenone, Poonam Jasrotia, Jiquan Chen, Stephen K. Hamilton & G. Philip Robertson
Over 13 million ha of former cropland are enrolled in the US Conservation Reserve Program (CRP), providing well-recognized biodiversity, water quality, and carbon (C) sequestration benefits that could be lost on conversion back to agricultural production. Here we provide measurements of the greenhouse gas consequences of converting CRP land to continuous corn, corn–soybean, or perennial grass for biofuel production. No-till soybeans preceded the annual crops and created an initial carbon debt of 10.6 Mg CO2...

Data from: Species richness effects on grassland recovery from drought depend on community productivity in a multisite experiment

De Boeck, Juliette M. G. Bloor, Sigi Berwaers, Carl Beierkuhnlein, Mohammed A. S. Arfin Khan, Iva Apostolova, Yasin Altan, Michaela Zeiter, Camilla Wellstein, Marcelo Sternberg, Andreas Stampfli, Giandiego Campetella, Sándor Bartha … & Juliette M.G. Bloor
Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine drought resistance and recovery at five temperate and Mediterranean grassland sites. Aboveground biomass production declined by 30% due to experimental drought (standardised local extremity by rainfall exclusion for 72–98 consecutive days). Species richness did not affect resistance but promoted recovery. Recovery was only positively affected by...

Data from: Effect of the landscape matrix on gene flow in a coastal amphibian metapopulation

Karen Cox, Joke Maes, Hans Van Calster & Joachim Mergeay
Functional connectivity is crucial for the persistence of a metapopulation, because migration among subpopulations enables recolonization and counteracts genetic drift, which is especially important in small subpopulations. We studied the degree and drivers of connectivity among occupied patches of a coastal dune metapopulation of the Natterjack Toad (Epidalea calamita Laurenti), on the basis of microsatellite variation. As spatial landscape heterogeneity is expected to influence dispersal and genetic structure, we analyzed which landscape features affect functional...

Data from: Interpreting ELISA analyses from wild animal samples: some recurrent issues and solutions

Romain Garnier, Raül Ramos, Ana Sanz-Aguilar, Maud Poisbleau, Henri Weimerskirch, Sarah Burthe, Jeremy Tornos & Thierry Boulinier
1. Many studies in disease and immunological ecology rely on the use of assays that quantify the amount of specific antibodies (immunoglobulin) in samples. Enzyme-Linked Immuno Sorbent Assays (ELISAs) are increasingly used in ecology due to their availability for a broad array of antigens and the limited amount of sampling material they require. Two recurrent methodological issues are nevertheless faced by researchers: (i) the limited availability of immunological assays and reagents developed for non-model species,...

Data from: Cooperative breeding shapes post-fledging survival in an Afrotropical forest bird

Dries Van De Loock, Diederik Strubbe, Liesbeth De Neve, Mwangi Githiru, Erik Matthysen & Luc Lens
While avian group living typically accrues multiple benefits, it is yet unknown how these benefits manifest post- fledging. Here, by using an indirect radio- telemetry approach, we found that cooperation increases fledgling survival in an Afrotropical forest bird. This result indicates the importance of considering the full breeding cycle in cooperative breeding research, which may ultimately lead to a better understanding of evolutionary drivers of cooperation.

Data from: Decreasing parental task specialization promotes conditional cooperation

Nolwenn Fresneau, Arne Iserbyt, Tiffanie Kortenhoff, Marcel Eens & Wendt Müller
How much to invest in parental care and by who remain puzzling questions fomented by a sexual conflict between parents. Negotiation that facilitates coordinated parental behaviour may be key to ease this costly conflict. However, understanding cooperation requires that the temporal and sex-specific variation in parental care, as well as its multivariate nature is considered. Using a biparental bird species and repeated sampling of behavioural activities throughout a major part of reproduction, we show a...

Data from: Climate-related environmental variation in a visual signalling device: the male and female dewlap in Anolis sagrei lizards

Tess Driessens, Simon Baeckens, Manuela Balzarolo, Bieke Vanhooydonck, Katleen Huyghe & Raoul Van Damme
Animals communicate using a variety of signals that differ dramatically among and within species. The astonishing dewlap diversity in anoles has attracted considerable attention in this respect. Yet, the evolutionary processes behind it remain elusive and have mostly been explored for males only. Here, we considered Anolis sagrei males and females to study signal divergence among populations. First, we assessed the degree of variation in dewlap design (size, pattern, colour) and displays by comparing 17...

Data from: Invasive earthworms erode soil biodiversity: a meta-analysis

Olga Ferlian, Nico Eisenhauer, Martin Aguirrebengoa, Mariama Camara, Irene Ramirez-Rojas, Fabio Santos, Krizler Tanalgo & Madhav P. Thakur
1. Biological invasions pose a serious threat to biodiversity and ecosystem functioning across ecosystems. Invasions by ecosystem engineers, in particular, have been shown to have dramatic effects in recipient ecosystems. For instance, invasion by earthworms, a belowground invertebrate ecosystem engineer, in previously earthworm-free ecosystems dramatically alters the physico-chemical characteristics of the soil. Studies have shown that such alterations in the soil can have far-reaching impacts on soil organisms, which form a major portion of terrestrial...
