Data from: Historical amphibian declines and extinctions in Brazil linked to chytridiomycosis

Tamilie Carvalho, C. Guilherme Becker & Luis Felipe Toledo
The recent increase in emerging fungal diseases is causing unprecedented threats to biodiversity. The origin of spread of the frog-killing fungus Batrachochytrium dendrobatidis (Bd) is a matter of continued debate. To date, the historical amphibian declines in Brazil could not be attributed to chytridiomycosis; the high diversity of hosts coupled with the presence of several Bd lineages predating the reported declines raised the hypothesis that a hypervirulent Bd genotype spread from Brazil to other continents...

Data from: Rare frost events reinforce tropical savanna-forest boundaries

William A. Hoffmann, Samuel W. Flake, Rodolfo C.R. Abreu, Natashi A.L. Pilon, Davi R. Rossatto, Giselda Durigan & Rodolfo C. R. Abreu
1) The ability of vegetation to ameliorate or exacerbate environmental extremes can generate feedbacks that mediate the distribution of biomes. It has been suggested that feedbacks between vegetation and frost damage may be important for maintaining savanna, particularly at the edge of the tropics. 2) We quantified frost damage and air temperature across a network of 30 permanent plots distributed across tropical savanna-forest boundaries in Brazil during an uncommonly hard frost. 3) Tree cover strongly...

Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jonathan R. Bridle, Gabriela Castaño-Meneses, Bruno Corbara, Gianfranco Curletti, Wesley Duarte Da Rocha, Domir De Bakker, Jacques H.C. Delabie, Alain Dejean, Laura L. Fagan, Andreas Floren, Roger L. Kitching … & Jacques H. C. Delabie
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14...

Data from: Flower colour and visitation rates of Costus arabicus support the \"bee avoidance\" hypothesis for red-reflecting hummingbird-pollinated flowers

Pedro Joaquim Bergamo, André Rodrigo Rech, Vinícius L. G. Brito & Marlies Sazima
Floral colour mediates plant–pollinator interactions by often signalling floral resources. In this sense, hummingbird-pollinated flowers are frequently red-coloured, and there are two tentative hypotheses to explain this pattern: 1. hummingbirds are attracted to red due its easier detection and 2. bees are sensorially excluded from red flowers. The second hypothesis is based on bees’ red colour blindness, which lead them to be less frequent and less important than hummingbirds as pollinators of red-reflecting flowers. Here,...

Data from: Genetic structure and diversity of populations of polyploid Tibouchina pulchra Cogn. (Melastomataceae) under different environmental conditions in extremes of an elevational gradient

Vinícius L. G. Brito, Gustavo M. Mori, Bianca B. Z. Vigna, Marianne Azevedo-Silva, Anete P. Souza & Marlies Sazima
The genetic structure and diversity of plants may change significantly in an elevational gradient because different elevations regulate different ecological conditions. Several factors may influence genetic variation, such as mutations, selection, genetic drift, and gene flow. The aim of the present study was to evaluate the genetic structure and diversity of populations of Tibouchina pulchra Cogn. (Melastomataceae) trees in two extremes of an elevational gradient experiencing different environmental conditions. Nine polymorphic microsatellite loci were used...

Data from: Molecular responses to freshwater limitation in the mangrove tree Avicennia germinans (Acanthaceae)

Mariana Vargas Cruz, Gustavo Maruyama Mori, Dong-Ha Oh, Maheshi Dassanayake, Maria Imaculada Zucchi, Rafael Silva Oliveira & Anete Pereira De Souza
Environmental variation along the geographical space can shape populations by natural selection. In the context of global warming and changing precipitation regimes, it is crucial to understand the role of environmental heterogeneity in tropical trees adaptation, given their disproportional contribution to water and carbon biogeochemical cycles. Here, we investigated how heterogeneity in freshwater availability along tropical wetlands has influenced molecular variations of the Black Mangrove (Avicennia germinans). Fifty-seven trees were sampled in seven sites differing...

Vellozioid roots allow for habitat specialisation among rock- and soil-dwelling Velloziaceae in campos rupestres

Anna Abrahão, Patrícia De Britto Costa, Grazielle Sales Teodoro, Hans Lambers, Diego L. Nascimento, Sara A. L. De Andrade, Megan H. Ryan & Rafael S. Oliveira
1. Plant growth on harsh substrates (habitat specialisation) requires specific traits to cope with stressful conditions. 2. We tested whether traits related to nutrient acquisition (root colonisation by fungal symbionts, and plant morphological and physiological specialisations), and nutrient use (leaf nitrogen (N) and phosphorus (P) concentrations and N- and P-remobilisation efficiency), were related to habitat specialisation for 27 species of Velloziaceae growing either in soil or on rocks in extremely P-impoverished campos rupestres habitats. If...

Associated evolution of fruit size, fruit color and spines in Neotropical palms

Lucas Ferreira Do Nascimento, , Renske E. Onstein, W. Daniel Kissling & Mathias M. Pires
Understanding how ecological interactions have shaped the evolutionary dynamics of species traits remains a challenge in evolutionary ecology. Combining trait evolution models and phylogenies, we analyzed the evolution of characters associated with seed dispersal (fruit size and color) and herbivory (spines) in Neotropical palms to infer the role of these opposing animal-plant interactions in driving evolutionary patterns. We found that the evolution of fruit color and fruit size were associated in Neotropical palms, supporting the...

Multitrophic richness enhances ecosystem multifunctionality of tropical shallow lakes

Dieison A Moi, Gustavo Q Romero, Pablo A P Antiqueira, Roger P Mormul, Franco Teixeira-De-Mello & Claudia C Bonecker
1. Biodiversity provides multiple functions and services to ecosystems. However, the role of biodiversity in sustaining multiple functions simultaneously (multifunctionality) is still poorly understood in natural communities, especially in hyperdiverse tropical freshwater ecosystems. Studies have focused on the effect of single trophic groups on ecosystem function and on individual ecosystem functions. 2. Using a 16-year database from tropical shallow lakes, we combined species richness of nine trophic groups into a unique measurement of multitrophic richness....

Ana Julia Pinto Fonseca S. Afonso, António Pinto-Almeida, Tiago M. F. Mendes, Pedro Ferreira, Silvana Belo, Fernanda F. Anibal, Silmara M. Allegretti, Carlos Alexandre Galinaro, Emanuel Carrilho & Ana B Abecassis
The extensive use of Praziquantel (PZQ), the only drug available to treat schistosomiasis, has brought concern about the emergence of PZQ-resistance/tolerance by Schistosoma spp., thus reaffirming an urge for the development of new treatment alternatives. Therefore, it is imperative and urgent to study this phenomenon trying to understand what is involved in its occurrence. Studies of Schistosoma spp. genome, transcriptome and proteome are crucial to better understand this situation. By stepwise drug pressure from a...

Underlying microevolutionary processes parallel macroevolutionary patterns in ancient Neotropical Mountains - Ecological Niche Modeling and Corridors files

Marcos Vinicius Dantas-Queiroz, Tami Da Costa Cacossi, Bárbara Simões Santos Leal, Cleber Juliano Neves Chaves, Thais Vasconcelos, Leonardo De Melo Versieux & Clarisse Palma-Silva
Aim Ancient climatic fluctuations are invoked as the main driving force that generates the astonishing biodiversity in ancient mountains. As a result, endemism and spatial turnover are usually high and few species are widespread among entire mountain ranges, precluding the understanding of origins of macroevolutionary patterns. Here, we used a species endemic to, but widespread in, one of the most species-rich ancient mountains on the globe to test how environmental changes acted on them and...

Data from: Analysis of the PEBP gene family and identification of a novel FLOWERING LOCUS T orthologue in sugarcane

Julien Venail, Paolo Da Silva Santos, Joao Manechini, Leonardo Alves, Maximiliano Scarpari, Thais Falcao, Elisson Romanel, Michael Brito, Renato Vicentini, Luciana Pinto & Stephen Jackson
Sugarcane (Saccharum spp.) is an important economic crop for both sugar and biomass, the yields of which are negatively affected by flowering. The molecular mechanisms controlling flowering in sugarcane are nevertheless poorly understood. RNA-seq data analysis and database searches have enabled a comprehensive description of the PEBP gene family in sugarcane. It is shown to consist of at least 13 FLOWERING LOCUS T (FT)-like genes, two MOTHER OF FT AND TFL (MFT)-like genes, and four...

Data from: Land use alters trophic redundancy and resource flow through stream food webs

Elliott L. Price, Mirela Sertić Perić, Romero Q. Gustavo & Pavel Kratina
1. The changes to physical and chemical ecosystem characteristics as a response to pervasive and intensifying land use have the potential to alter the consumer-resource interactions and to rewire the flow of energy through entire food webs. 2. We investigated these structural and functional properties of food webs in stream ecosystems distributed across woodland, agricultural and urban areas in the Zagreb region of Croatia. We compared resource availability and consumer diet composition using stable isotope...
