Comparative Proteomics Reveals Characteristic Proteins on Praziquantel-resistance in Schistosoma mansoniAna Julia Pinto Fonseca S. Afonso, António Pinto-Almeida, Tiago M. F.

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...
Seed dispersal and predation by animals often drive plant regeneration. In tropical savannas, such as the Cerrado of Brazil, fire is also a key process in ecosystem dynamics, consuming the lower vegetation strata and killing wildlife, but how fire affects seed-animal interactions is virtually unknown. We investigated the effects of prescribed fires on the removal of diaspores from Miconia rubiginosa and sunflower Helianthus annuus in Cerrado from southeast Brazil. Using plots burned one month or...
Plant-animal interactions may facilitate biological invasions. The African grass Urochloa decumbens is an aggressive invader in the Cerrado. We demonstrate that native ants are dispersing the seeds to short distances, allowing the gradual spread of the invasive to sites without the need of great anthropogenic soil disturbances.
RAD-seq data from: Evidence of local adaptation despite strong drift in a Neotropical patchily distributed bromeliadBárbara Simões Santos Leal, Cleber Juliano Neves Chaves, Vanessa Araujo Graciano, Christophe Boury, Luis Alberto Pillaca Huacre, Myriam Heuertz & Clarisse Palma-Silva
Both genetic drift and divergent selection are predicted to be drivers of population differentiation across patchy habitats, but the extent to which these forces act on natural populations to shape traits is strongly affected by species' ecological features. In this study, we infer the genomic structure of Pitcairnia lanuginosa, a widespread herbaceous perennial plant with a patchy distribution. We sampled populations in the Brazilian Cerrado and the Central Andean Yungas and discovered and genotyped SNP...
Differential speciation rates, colonization time, and niche conservatism affect community assembly across adjacent biogeographical regionsRonildo Benício, Diogo Provete, Mariana Lyra, Jani Heino, Célio Haddad, Denise De C. Rossa-Feres & Fernando Da Silva
Aim: To test the importance of evolutionary and biogeographic processes in shaping the assembly of local frog communities in two adjacent regions (hereafter, coastal and inland regions) with different historical signatures. We asked two main questions: i) why does the coastal region harbor more frog species than the inland region? and ii) how do these processes affect the relationship between the spatial variation of taxonomic, phylogenetic, and functional diversities within and across these regions? Location:...
The influence of biogeographical and evolutionary histories on morphological trait-matching and resource specialization in mutualistic hummingbird-plant networksBo Dalsgaard, Pietro Maruyama, Jesper Sonne, Katrine Hansen, Thais Zanata, Stefan Abrahamczyk, Ruben Alarcon, Andréa Araujo, Francielle Araújo, Silvana Buzato, Edgar Chávez-González, Aline Coelho, Pete Cotton, Román Díaz-Valenzuela, Maria Dufke, Paula Enríquez, Manoel Martins Dias Filho, Erich Fischer, Glauco Kohler, Carlos Lara, Flor Maria Las-Casas, Liliana Rosero Lasprilla, Adriana Machado, Caio Machado, Maria Maglianesi … & Ana M. Martín González
Functional traits can determine pairwise species interactions, such as those between plants and pollinators. However, the effects of biogeography and evolutionary history on trait-matching and trait-mediated resource specialization remain poorly understood. We compiled a database of 93 mutualistic hummingbird-plant networks (including 181 hummingbird and 1,256 plant species), complemented by morphological measures of hummingbird bill and floral corolla length. We divided the hummingbirds into their principal clades and used knowledge on hummingbird biogeography to divide the...
Delayed color maturation of a sexual ornament in males of a damselfly: crypsis, female mimicry or both?Rodrigo Cezário, Eralci Therezio, Alexandre Marletta, Stanislav Gorb & Rhainer Guillermo-Ferreira
Dynamic signals are a widespread phenomenon in several taxa, usually associated with intraspecific communication. On the other hand, dynamic iridescent signals are only detectable at specific angles of illumination; hence, the animal can hide the signal to avoid detection when necessary. This structural coloration is mostly dependent on illumination, contrast against the background and the vision of the receiver. Complex behavioural displays may be coupled with structural coloration to create dynamic visual signals that enhance...
