INCREASING CORAL RESILIENCE TO BLEACHING THROUGH MICROBIOME MANIPULATION

Raquel Peixoto, Phillipe Rosado, Deborah Leite, Gustavo Duarte, Ricardo Chaloub, Guillaume Jospin, Jonathan Eisen, David Bourne, Ulisses Da Rocha, João Saraiva & Francisco Dini-Andreote
Although the early coral reef-bleaching warning system (NOAA/USA) is established, there is no feasible treatment that can minimize temperature bleaching and/or disease impacts on corals in the field. Here, we present the first attempts to extrapolate the widespread and well-established use of bacterial consortia to protect or improve health in other organisms (e.g., humans and plants) to corals. Manipulation of the coral-associated microbiome was facilitated through addition of a consortium of native (isolated from Pocillopora...

Data from: The balance of canopy and soil effects determines intraspecific differences in foundation species’ effects on associated plants

Nuria Pistón, Richard Michalet, Christian Schöb, Petr Macek, Cris Armas & Francisco I. Pugnaire
1. The impact of plant-plant interactions on species diversity patterns has been broadly addressed in stressful environments, such as alpine ecosystems, where foundation species promote species richness by creating habitat for other species. However, foundation species with contrasting phenotypes might modify the microhabitat differently, which would alter the subordinate community composition, and coincide with distinct feedback effects of those subordinate species on the foundation species. However, the precise interaction mechanisms that facilitate species are not...

Data from: Planning protected areas network that are relevant today and under future climate change is possible: the case of Atlantic Forest endemic birds

Mariana M. Vale, Thiago V. Souza, Maria Alice S. Alves & Renato Crouzeilles
Background. A key strategy in biodiversity conservation is the establishment of protected areas. In the future, however, the redistribution of species in response to ongoing climate change is likely to affect species’ representativeness in those areas. Here we quantify the effectiveness of planning protected areas network to represent 151 birds endemic to the Brazilian Atlantic Forest hotspot, under current and future climate change conditions for 2050. Methods. We combined environmental niche modeling and systematic conservation...

Data from: Diversity in form and function: vertical distribution of soil fauna mediates multidimensional trait variation

Jacintha Ellers, Matty P. Berg, André T.C. Dias, Simone Fontana, Astra Ooms & Marco Moretti
1. It has been widely recognized that species show extensive variation in form and function. Based on species’ attributes they can be positioned along major axes of variation, which are often defined by life history traits, such as number of offspring, age at maturity or generation time. Less emphasis has been given in this respect to tolerance traits, especially to resistance to abiotic stress conditions, which often determine community (dis)assembly and distribution. 2. Soil fauna...

Data from: Ecological mechanisms and phylogeny shape invertebrate stoichiometry: a test using detritus-based communities across Central and South America

Angélica L. González, Régis Céréghino, Olivier Dézerald, Vinicius F. Farjalla, Céline Leroy, Barbara A. Richardson, Michael J. Richardson, Gustavo Q. Romero & Diane S. Srivastava
1. Stoichiometric differences among organisms can affect trophic interactions and rates of nutrient cycling within ecosystems. However, we still know little about either the underlying causes of these stoichiometric differences, or the consistency of these differences across large geographic extents. 2. Here we analyze elemental (carbon, nitrogen, phosphorus) composition of 872 aquatic macroinvertebrates (71 species) inhabiting tank bromeliads (n = 140) from five distantly located sites across Central and South America to (1) test phylogenetic,...

Data from: Multiple factors behind early diversification of skull morphology in the continental radiation of New World monkeys

Leandro Aristide, Paul Bastide, Sergio F. Dos Reis, Thaís M. Pires Dos Santos, Ricardo Tadeu Lopes & Sergio Ivan Perez
Understanding the origin of diversity is a fundamental problem in evolutionary biology. The null expectation for the evolutionary diversification is that all changes in biological diversity are the result of random processes. Adaptive radiations depart from this expectation as ecological factors and natural selection are supposed to play a central role in driving exceptional diversification. However, it is not well understood how large-scale continental radiations, given their characteristics, fit to these opposing theoretical models. Here,...

Data from: Incomplete lineage sorting impacts the inference of macroevolutionary regimes from molecular phylogenies when concatenation is employed: an analysis based on Cetacea

Anieli G. Pereira & Carlos G. Schrago
Interest in methods that estimate speciation and extinction rates from molecular phylogenies has increased over the last decade. The application of such methods requires reliable estimates of tree topology and node ages, which are frequently obtained using standard phylogenetic inference combining concatenated loci and molecular dating. However, this practice disregards population-level processes that generate gene tree/species tree discordance. We evaluated the impact of employing concatenation and coalescent-based phylogeny inference in recovering the correct macroevolutionary regime...

Data from: The use of metabarcoding for meiofauna ecological patterns assessment

Laiza Cabral De Faria, Maikon Di Domenico, Sónia C. S. Andrade, Monique Cristina Dos Santos, Gustavo Fonseca, Joana Zanol & A. Cecilia Z. Amaral
Marine meiofauna comprises up to 22 phyla. Its morphological identification requires time and taxonomists' expertise, and molecular tools can make this task faster. We aim to disentangle meiofaunal diversity patterns at Araçá Bay by applying a model selection approach and estimating the effectiveness of metabarcoding (18S rDNA) and morphological methods for estimating the response of meiofauna diversity in small-scale interactions with environmental variables. A rarefaction curve indicated that ten samples were sufficient for estimating the...

Data from: Functional traits and environmental conditions predict community isotopic niches and energy pathways across spatial scales

Olivier Dézerald, Diane S. Srivastava, Régis Céréghino, Jean-François Carrias, Bruno Corbara, Vinicius F. Farjalla, Céline Leroy, Nicholas A. C. Marino, Gustavo C. O. Piccoli, Barbara A. Richardson, Michael J. Richardson, Gustavo Q. Romero & Angélica L. González
1. Despite ongoing research in food web ecology and functional biogeography, the links between food-web structure, functional traits and environmental conditions across spatial scales remain poorly understood. Trophic niches, defined as the amount of energy and elemental space occupied by species and food webs, may help bridge this divide. 2. Here, we ask how the functional traits of species, the environmental conditions of habitats and the spatial scale of analysis jointly determine the characteristics of...

Data from: Interactive effects of climate change and biodiversity loss on ecosystem functioning

Aliny P. F. Pires, Diane S. Srivastava, Nicholas A. C. Marino, A. Andrew M. MacDonald, Marcos Paulo Figueiredo-Barros & Vinicius F. Farjalla
Climate change and biodiversity loss are expected to simultaneously affect ecosystems, however research on how each driver mediates the effect of the other has been limited in scope. The multiple stressor framework emphasizes non-additive effects, but biodiversity may also buffer the effects of climate change, and climate change may alter which mechanisms underlie biodiversity-function relationships. Here, we performed an experiment using tank bromeliad ecosystems to test the various ways that rainfall changes and litter diversity...

Data from: Assessing metabolic constraints on the maximum body size of actinopterygians: locomotion energetics of Leedsichthys problematicus (Actinopterygii, Pachycormiformes)

Humberto G. Ferrón, Borja Holgado, Jeff J. Liston, Carlos Martínez Pérez & Hector Botella
Maximum sizes attained by living actinopterygians are much smaller than those reached by chondrichthyans. Several factors, including the high metabolic requirements of bony fishes, have been proposed as possible body-size constraints but no empirical approaches exist. Remarkably, fossil evidence has rarely been considered despite some extinct actinopterygians reaching sizes comparable to those of the largest living sharks. Here, we have assessed the locomotion energetics of Leedsichthys problematicus, an extinct gigantic suspension-feeder and the largest actinopterygian...
