Data from: Phylogenetic eigenvectors and non-stationarity in the evolution of theropod dinosaur skulls

Jose A. F. Diniz-Filho, Davi M. C. C. Alves, Fabricio Villalobos, Manabu Sakamoto, Steve L. Brusatte & Luis M. Bini
Despite the longstanding interest in non-stationarity of both phenotypic evolution and diversification rates, only recently have methods been developed to study this property. Here, we propose a methodological expansion of the Phylogenetic Signal Representation (PSR) curve based on phylogenetic eigenvectors to test for non-stationarity. The PSR is built by plotting the coefficients of determination R2 from Phylogenetic Eigenvector Regression (PVR) models increasing the number of phylogenetic eigenvectors against the accumulated eigenvalues. The PSR curve is...

Data from: Is there a correlation between abundance and environmental suitability derived from ecological niche modelling? A meta-analysis

Marcelo M. Weber, Richard D. Stevens, José Alexandre F. Diniz-Filho & Carlos Eduardo V. Grelle
It is thought that species abundance is correlated with environmental suitability and that environmental variables, scale, and type of model fitting can confound this relationship. We performed a meta-analysis to (i) test whether species abundance is positively correlated with environmental suitability derived from correlative ecological niche models (ENM), (ii) test whether studies encompassing large areas within a species range (>50%) exhibited higher AS correlations than studies encompassing small areas within a species range (<50%), (iii)...

Data from: You don’t belong here: explaining the excess of rare species in terms of habitat, space and time

Luciano F. Sgarbi & Adriano S. Melo
Ecological communities are composed of a few common and several rare species. Many studies have evaluated the shape of abundance distribution curves, but few studies have assessed the causes of rarity. Using a dataset of stream macroinvertebrates, we investigated whether the excess of rare species in three focal communities of stones in riffles were common i) in other habitats at the same stream site and period of sampling (Environment), ii) in other stream sites in...

Data from: Biotransformation of labdane and halimane diterpenoids by two filamentous fungi strains

Afif F. Monteiro, Cláudia Seidl, Vanessa G.P. Severino, Carmen Lúcia Cardoso & Ian Castro-Gamboa
Biotransformation of natural products by filamentous fungi is a powerful and effective approach to achieve derivatives with valuable new chemical and biological properties. Despite diterpenoid substrates exhibit good susceptibility towards fungi enzymes, there have been no studies concerning the microbiological transformation of halimane-type diterpenoids up to now. In this work, we investigated the capability of Fusarium oxysporum (a fungus isolated from the rhizosphere of Senna spectabilis) and Myrothecium verrucaria (an endophyte) to transform halimane (1)...

Daniel S. Karp, Rebecca Chaplin-Kramer, Timothy D. Meehan, Emily A. Martin, Fabrice DeClerck, Heather Grab, Claudio Gratton, Lauren Hunt, Ashley E. Larsen, Alejandra Martínez-Salinas, Megan E. O’Rourke, Adrien Rusch, Katja Poveda, Mattias Jonsson, Jay A. Rosenheim, Nancy A. Schellhorn, Teja Tscharntke, Stephen D. Wratten, Wei Zhang, Aaron L. Iverson, Lynn S. Adler, Matthias Albrecht, Audrey Alignier, Gina M. Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Ludmilla Aguiar, Maria João Ramos Pereira, Marlon Zortea, Ricardo Machado, Ludmilla M. S. Aguiar, Maria João R. Pereira, Marlon Zortéa & Ricardo B. Machado
Aim: Field surveys are necessary to overcome Wallacean shortfalls. The task is even more important when human pressure on tropical – megadiverse – ecosystems is considered. However, due to financial constraints, spatial and temporal prioritization is required. Here we used the concept of environmental complementarity to identify non-surveyed regions for bats that are environmentally different from other already surveyed regions. We highlighted regions in Brazil where field inventories could be conducted to locate new occurrences...

Negative effect of turbidity on prey capture for both visual and non-visual aquatic predators

Jean Ortega, Bruno Figueiredo, Weferson Da Graça, Angelo Agostinho & Luis Bini
1. Turbidity plays an important role in aquatic predator-prey interactions. Increases in turbidity are expected to reduce prey capture rates, especially for visually oriented predators. However, there is also evidence indicating that turbidity may have little or no effect on predation rates. 2. Here, we conducted a systematic review and meta-analysis of the relationship between turbidity and capture rate. We explored possible sources of heterogeneity in the effect sizes (capture strategy, predator’s body size, relative...

Holocene climate changes explain the spatial pattern in genetic diversity in populations of Cyperus papyrus from Southeast Africa wetlands

Elias Luís Maxombe, Lucas Vieira & Rosane Collevatti
Wetlands are one of the most threatened ecosystems in the world because more than 70% of the area worldwide has been lost since 1900. Wetland plant species rely greatly on water for seeds and propagules, which may lead to a downstream unidirectional dispersal and accumulation of genetic diversity downstream. However, several species show no support for unidirectional genetic diversity, revealing the complexity of population dynamics and gene flow in wetlands. Here, we used microsatellite loci...

Data from: Phylogenetic uncertainty revisited: implications for ecological analyses

Thiago Fernando Rangel, Robert K. Colwell, Gary R. Graves, Karolina Fučíková, Carsten Rahbek & José Alexandre F. Diniz-Filho
Ecologists and biogeographers usually rely on a single phylogenetic tree to study evolutionary processes that affect macroecological patterns. This approach ignores the fact that each phylogenetic tree is a hypothesis about the evolutionary history of a clade, and cannot be directly observed in nature. Also, trees often leave out many extant species, or include missing species as polytomies because of a lack of information on the relationship among taxa. Still, researchers usually do not quantify...

Data from: Multi-objective optimization for plant germplasm collection conservation of genetic resources based on molecular variability

Shana Schlottfeldt, Maria Emília M. T. Walter, Andre Carlos P. L. F. Carvalho, Thannya N. Soares, Mariana P. C. Telles, Rafael D. Loyola & Jose Alexandre F. Diniz-Filho
Germplasm collections play a significant role among strategies for conservation of diversity. It is common to select a core collection to represent the genetic diversity of a germplasm collection, in order to minimize the cost of conservation, while ensuring the maximization of genetic variation. We aimed to solve two main problems: (1) to select a set of individuals, from an in situ data set, that is genetically complementary to an existing germplasm collection, and (2)...

Data from: Correlation between genetic diversity and environmental suitability: taking uncertainty from ecological niche models into account

José Alexandre F. Diniz-Filho, Hauanny Rodrigues, Mariana Pires De Campos Telles, Guilherme De Oliveira, Levi Carina Terribile, Thannya Nascimento Soares & João Carlos Nabout
The hindcast of shifts in the geographical ranges of species as estimated by ecological niche modelling (ENM) has been coupled with phylogeographical patterns, allowing the inference of past processes that drove population differentiation and genetic variability. However, more recently, some studies have suggested that maps of environmental suitability estimated by ENM may be correlated to species' abundance, raising the possibility of using environmental suitability to infer processes related to population demographic dynamics and genetic variability....

Data from: Biodiversity in perennial and intermittent rivers: a meta-analysis

Maria Soria, Catherine Leigh, Thibault Datry, Luis Mauricio Bini & Nuria Bonada
Comprehensive knowledge of the effects of disturbances on biodiversity is crucial for conservation and management, not least because ecosystems with low biodiversity may be the most vulnerable. In rivers, the role of disturbance in shaping aquatic biodiversity has mainly focused on floods. Perennial rivers (PRs) often flood, whereas intermittent rivers (IRs) flood, stop flowing and dry. Despite the recent and significant increase in research on IRs, controversy remains about whether they are more or less...

Color lures in orb-weaving spiders: a meta-analysis

Nathalia Ximenes, Vinicius Moraes, Jean Ortega & Felipe Gawryszewski
Lures are deceptive strategies that exploit sensory biases in prey, usually mimicking a prey’s mate or food item. Several predators exploit plant-pollinator systems, where visual signals are an essential part of interspecific interactions. Many diurnal, and even nocturnal, orb-web spiders present conspicuous body coloration or bright color patches. These bright colors are regarded as color-based lures that exploit biases present in insect visual systems, possibly mimicking flower colors. The prey attraction hypothesis was proposed more...

Data from: Current climate, but also long-term climate changes and human impacts, determine the geographic distribution of European mammal diversity

Ana Margarida Coelho Dos Santos, Marcus Cianciaruso, A. Marcia Barbosa, Luis Mauricio Bini, José Alexandre Diniz-Filho, Frederico Augusto Faleiro, Sidney Gouveia, Rafael Loyola, Nagore Medina, Thiago Rangel, Geiziane Tessarolo & Joaquín Hortal
Aim. Historical climate variations, current climate and human impacts are known to influence current species richness, but their effects on phylogenetic and trait diversity have been seldom studied. We investigated the relationship of these three factors with the independent variations of species, phylogenetic and trait diversity of European mammals. Considering the position of the 0ºC isotherm in the Last Glacial Maximum as a tipping point, we tested the following hypotheses: northern European assemblages host less...

Thiago Bernardi Vieira, Leandro Schlemmer Brasil, Liriann Chrisley Nascimento Da Silva, Francisco Leonardo Tejerina Garro, Pedro De Podestà Uchôa De Aquino, Paulo Santos Pompeu & Paulo De Marco
The identification of the mechanisms underlying co-occurrence patterns of species is a way to identify which processes (niche, neutral or both) structure metacommunities. In this paper, our goals are to identify patterns of co-occurrence in neotropical stream fish and determine which processes structure the metacommunity and the gradients that underlie this structure. Our results pointed out that the metacommunity formed by the total pool of species is structured by a nested pattern (Hyperdispersed Species Loss)...

Amphbian larvae survey at Emas National Park, Brazil (2012/2013, 2014/2015, 2017/2018)

Fausto Nomura, Ingrid Beatriz Ferreira Paixão & Gabriela Alves-Ferreira
Multiple factors contribute to explaining the composition and structure of communities and the niche is still the most used theory to describe how organisms interact with such factors to generate biological communities’ patterns. Both biotic and abiotic aspects of the environment along with the geographic space interact in complex ways with the behavior and physiological tolerance of organisms to structure a community. In this study, we tested the potential effects of the environment and space...

Data from: Humidity levels drive reproductive modes and phylogenetic diversity of amphibians in the Brazilian Atlantic Forest

Fernando Rodrigues Silva, Mário Almeida-Neto, Vitor Hugo Mendonça Do Prado, Célio Fernando Baptista Haddad & Denise De Cerqueira Rossa-Feres
AIM: The diversity of reproductive modes among amphibians provides a striking example of how differences in the biology of species furnish can provide important explanations for species distribution patterns on a broad scale. We hypothesized that sites with a higher humidity level will support more different modes of reproduction than drier sites and will consequently exhibit a higher phylogenetic diversity. Furthermore, we predict that if there is a gradient in the tolerance of reproductive modes...
