Negative impacts of dominance on bee communities: Does the influence of invasive honey bees differ from native bees?

Lucas Alejandro Garibaldi, Lucas Garibaldi, Néstor Pérez-Méndez, Guaraci Cordeiro, Alice Hughes, Michael Orr, Isabel Alves Dos Santos, Breno Freitas, Favízia Freitas De Oliveira, Gretchen Lebuhn, Ignasi Bartomeus, Marcelo Aizen, Patricia Andrade, Betina Blochtein, Danilo Boscolo, Patricia Drumond, Maria Gaglianone, Barbara Gemmill-Herren, Rosana Halinski, Cristiane Krug, Marcia Maues, Lucia Piedade Kiill, Mardiore Pinheiro, Carmen Pires & Blandina Felipe Viana
Invasive species can reach high abundances and dominate native environments. One of the most impressive examples of ecological invasions is the spread of the African sub-species of the honey bee throughout the Americas, starting from its introduction in a single locality in Brazil. The invasive honey bee is expected to more negatively impact bee community abundance and diversity than native dominant species, but this has not been tested previously. We developed a comprehensive and systematic...

Data from: Diversification by host switching and dispersal shaped the diversity and distribution of avian malaria parasites in Amazonia

Alan Fecchio, Jeffrey Andrew Bell, Michael David Collins, Izeni Pires Farias, Christopher Harry Trisos, Joseph Andrew Tobias, Vasyl Volodymyr Tkach, Jason David Weckstein, Robert Eric Ricklefs & Henrique Batalha-Filho
Understanding how pathogens and parasites diversify through time and space is fundamental to predicting emerging infectious diseases. Here, we use biogeographic, coevolutionary and phylogenetic analyses to describe the origin, diversity, and distribution of avian malaria parasites in the most diverse avifauna on Earth. We first performed phylogenetic analyses using the mitochondrial cytochrome b (cyt b) gene to determine relationships among parasite lineages. Then, we estimated divergence times and reconstructed ancestral areas to uncover how landscape...

Heterogeneous agroecosystems support high diversity and abundance of trap nesting bees and wasps amongst tropical crops

Jeferson Coutinho, Catalina Coca, Danilo Boscolo & Blandina Viana
Land-use intensification for agricultural purposes modifies the structure of natural environments in various ways and at different spatial scales. These modifications can affect ecological processes and the community structure of multi-environment users such as solitary bees and wasps. Understanding the role of distinct habitat descriptors in promoting such changes is one of the major challenges of empirical studies. In this study, we use a multi-scale approach to evaluate how landscape compositional and configurational heterogeneity, vegetation...

Data from: Feeding effects on liver mitochondrial bioenergetics of Boa constrictor (Serpentes: Boidae)

Marina R. Sartori, Helena R. Da Mota Araujo, Claudia D.C. Navarro, Jose Eduardo De Carvalho & Andre Luis Da Cruz
Snakes are interesting examples of overcoming energy metabolism challenges as many species can endure long periods without feeding, and their eventual meals are of reasonably large sizes, thus exhibiting dual extreme adaptations. Consequently, metabolic rate increases considerably to attend to the energetic demand of digestion, absorption and, protein synthesis. These animals should be adapted to transition from these two opposite states of energy fairly quickly, and therefore we investigated mitochondrial function plasticity in these states....

Data from: A case study of extant and extinct Xenarthra cranium covariance structure: implications and applications to paleontology

Alex Hubbe, Diogo Melo & Gabriel Marroig
Most of the mammalian diversity is known only from fossils, and only a few of these fossils are well preserved or abundant. This under sampling poses serious problems for understanding mammalian phenotypic evolution under a quantitative genetics framework, since this framework requires estimation of a group's additive genetic variance-covariance matrix (G-matrix), which is impossible, and estimating a phenotypic variance-covariance matrix (P-matrix) requires larger sample sizes then what is often available for extinct species. One alternative...

Effects of tidal influence on the structure and function of prokaryotic communities in the sediments of a pristine Brazilian mangrove

Pieter Spealman, Carolina Santana, David Gresham, Vânia Maria Maciel Melo, Taíse Bomfim De Jesus & Fabio Alexandre Chinalia
Mangrove forests are ecosystems that constitute a large portion of the world’s coastline and span tidal zones below, between, and above the waterline, while the ecosystem as a whole is defined by the health of these tidal microhabitats. However, we are only beginning to understand tidal zone microbial biodiversity and the role of these microbiomes in nutrient cycling. While extensive research has characterized microbiomes in pristine versus anthropogenically impacted mangroves these have, largely, overlooked differences...

Treefrogs adjust their acoustic signals in response to harmonics structure of intruder calls

Lucas Forti & Diego Llusia
Spectral properties of animal acoustic signals may help individuals to assess the characteristics of rivals and to adjust their competitive strategies in territorial disputes. Thus, we hypothesize that the distribution of energy across frequency bands in anuran calls determine behavioral responses in male-male competition. Using playback experiments, we investigated the relevance of the harmonic calls in the acoustic communication of the treefrog Dendropsophus minutus. We exposed territorial males to three synthetic acoustic stimuli composed of...

The chicken or the egg? Plastome evolution and an independent loss of the inverted repeat in papilionoid legumes

Chaehee Lee, In-Su Choi, Domingos Cardoso, Haroldo De Lima, Luciano De Queiroz, Martin Wojciechowski, Robert Jansen & Tracey Ruhlman
The plastid genome (plastome), while surprisingly constant in gene order and content across most photosynthetic angiosperms, exhibits variability in several unrelated lineages. During the diversification history of the legume family Fabaceae, plastomes have undergone many rearrangements, including inversions, expansion, contraction and loss of the typical inverted repeat (IR), gene loss and repeat accumulation in both shared and independent events. While legume plastomes have been the subject of study for some time, most work has focused...

Quantitative genetics of extreme insular dwarfing: the case of red deer (Cervus elaphus) on Jersey

José Alexandre Felizola Diniz-Filho, Ana Santos, Elisa Barreto, Felipe Naves, Wanderson Santos, Kelly Souza, Rejane Santos-Silva, Ricardo Dobrovolski, Thannya Soares, Rosana Tidon, Zander Spigoloni, Thiago Rangel, Pasquale Raia, Joaquín Hortal & Lucas Jardim
Aim: The Island Rule – i.e. the tendency for body size to decrease in large mammals and increase in small mammals on islands has been commonly evaluated through macroecological or macroevolutionary, pattern-orientated approaches, which generally fail to model the microevolutionary processes driving either dwarfing or gigantism. Here, we seek to identify which microevolutionary process could have driven extreme insular dwarfism in the extinct dwarf red deer population on the island of Jersey. Location: Jersey, UK...

Data from: Measuring the magnitude of morphological integration: the effect of differences in morphometric representations and the inclusion of size

Fabio A Machado, Alex Hubbe, Diogo Melo, Arthur Porto & Gabriel Marroig
The magnitude of morphological integration is a major aspect of multivariate evolution, providing a simple measure of the intensity of association between morphological traits. Studies concerned with morphological integration usually translate phenotypes into morphometric representations to quantify how different morphological elements covary. Geometric and classic morphometric representations translate biological form in different ways, raising the question if magnitudes of morphological integration estimates obtained from different morphometric representations are compatible. Here we sought to answer this...

Exploration of plastid phylogenomic conflict yields new insights into the deep relationships of Leguminosae

Rong Zhang, Yin-Huan Wang, Jian-Jun Jin, Gregory Stull, Anne Bruneau, Domingos Cardoso, Luciano De Queiroz, Michael Moore, Shu-Dong Zhang, Si-Yun Chen, Jian Wang, De-Zhu Li & Ting-Shuang Yi
Phylogenomic analyses have helped resolve many recalcitrant relationships in the angiosperm tree of life, yet phylogenetic resolution of the backbone of the Leguminosae, one of the largest and most economically and ecologically important families, remains poor due to generally limited molecular data and incomplete taxon sampling of previous studies. Here, we resolve many of the Leguminosae's thorniest nodes through comprehensive analysis of plastome-scale data using multiple modified coding and noncoding datasets of 187 species representing...

Data from: Invasion-mediated effects on marine trophic interactions in a changing climate: positive feedbacks favour kelp persistence

Ricardo Miranda, Melinda Coleman, Alejandro Tagliafico, Maria Rangel, Lea Mamo, Francisco Barros & Brendan Kelaher
The interactive effects of ocean warming and invasive species are complex and remain a source of uncertainty for projecting future ecological change. Climate-mediated change to trophic interactions can have pervasive ecological consequences, but the role of invasion in mediating trophic effects is largely unstudied. Using manipulative experiments in replicated outdoor mesocosms, we reveal how near-future ocean warming and macrophyte invasion scenarios interactively impact gastropod grazing intensity and preference for consumption of foundation macroalgae (Ecklonia radiata...

Functional biogeography of Neotropical moist forests: trait-climate relationships and assembly patterns of tree communities

Bruno Pinho, Marcelo Tabarelli, Cajo Ter Braak, S. J. Wright, Victor Arroyo-Rodriguez, Maíra Benchimol, Bettina Engelbrecht, Simon Pierce, Peter Hietz, Bráulio Santos, Carlos Peres, Sandra Müller, Ian Wright, Frans Bongers, Madelon Lohbeck, Ülo Niinemets, Martijn Slot, Steven Jansen, Davi Jamelli, Renato Augusto Ferreira De Lima, Nathan Swenson, Richard Condit, Jos Barlow, Ferry Slik, Manuel Hernández-Ruedas … & Felipe Melo
Aim: Here we examine the functional profile of regional tree species pools across the latitudinal distribution of Neotropical moist forests, and test trait-climate relationships among local communities. We expected opportunistic strategies (acquisitive traits, small seeds) to be overrepresented in species pools further from the equator due to long-term instability, but also in terms of abundance in local communities in currently wetter, warmer and more seasonal climates. Location: Neotropics. Time period: Recent. Major taxa studied: Trees....

Data from: Directional selection effects on patterns of phenotypic (co)variation in wild populations

Ana Paula A. Assis, James L. Patton, Alex Hubbe & Gabriel Marroig
Phenotypic (co)variation is a prerequisite for evolutionary change, and understanding how (co)variation evolves is of crucial importance to the biological sciences. Theoretical models predict that under directional selection, phenotypic (co)variation should evolve in step with the underlying adaptive landscape, increasing the degree of correlation among co-selected traits as well as the amount of genetic variance in the direction of selection. Whether either of these outcomes occurs in natural populations is an open question and thus...

Data from: Urban rat races: spatial population genomics of brown rats (Rattus norvegicus) compared across multiple cities

Matthew Combs, Kaylee A. Byers, Bruno M. Ghersi, Michael J. Blum, Adalgisa Caccone, Federico Costa, Chelsea G. Himsworth, Jonathan L. Richardson & Jason Munshi-South
Urbanization often substantially influences animal movement and gene flow. However, few studies to date have examined gene flow of the same species across multiple cities. In this study, we examine brown rats (Rattus norvegicus) to test hypotheses about the repeatability of neutral evolution across four cities: Salvador, Brazil; New Orleans, USA; Vancouver, Canada; New York City, USA. At least 150 rats were sampled from each city and genotyped for a minimum of 15,000 genome-wide SNPs....

Data from: A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny

, Anne Bruneau, Nasim Azani, Marielle Babineau, Edeline Gagnon, Carole Sinou, Royce Steeves, Erin Zimmerman, C. Donovan Bailey, Lynsey Kovar, Madhugiri Nageswara-Rao, Hannah Banks, RuthP. Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...

Data from: Global population divergence and admixture of the brown rat (Rattus norvegicus)

Emily E. Puckett, Jane Park, Matthew Combs, Michael J. Blum, Juliet E. Bryant, Adalgisa Caccone, Federico Costa, Eva E. Deinum, Alexandra Esther, Chelsea G. Himsworth, Peter D. Keightley, Albert Ko, Ake Lundkvist, Lorraine M. McElhinney, Serge Morand, Judith Robins, James Russell, Tanja M. Strand, Olga Suarez, Lisa Yon & Jason Munshi-South
Native to China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution. While black rats and the house mouse tracked the regional development of human agricultural settlements, brown rats did not appear in Europe until the 1500s, suggesting their range expansion was a response to relatively recent increases in global trade. We inferred the global phylogeography of brown rats using 32 k SNPs, and detected 13 evolutionary clusters within five expansion routes....

Riverscape properties contribute to the origin and structure of a hybrid zone in a Neotropical freshwater fish

Silvia Britto Barreto, L. Lacey Knowles, Paulo Roberto Affonso & Henrique Batalha-Filho
Understanding the structure of hybrid zones provides valuable insights about species boundaries and speciation, such as the evolution of barriers to gene flow and the strength of selection. In river networks, studying evolutionary processes in hybrid zones can be especially challenging, given the influence of past and current river properties along with biological species-specific traits. Here, we suggest that a natural hybrid zone between two divergent lineages of the sexually dimorphic Neotropical fish Nematocharax venustus...
