Data from: Disentangling the factors that shape bromeliad and ant communities in the canopies of cocoa agroforestry and preserved Atlantic Forest

Reuber Antoniazzi, Wesley DaRocha, Jacques Delabie, Götz Schroth, Geraldo Fernandes & Frederico Neves
In tropical forest canopies, host tree characteristics shape epiphyte communities, and both host tree characteristics and epiphytes determine invertebrate communities, e.g., ants. Tree height is among the factors most often mentioned as a strong predictor for both bromeliad and ant communities. However, many factors interact dynamically in shaping the tree-bromeliad-ant association. Here, we investigated the effects of the host tree and canopy structural characteristics on both bromeliads and ants. We sampled bromeliads on 180 trees...

Beta diversity of aquatic macroinvertebrate assemblages associated with leaf patches in neotropical montane streams

Marcos Callisto, Marden Linares, , Robert Hughes, Marcelo Moretti, Diego Macedo & Ricardo Ribeiro De Castro Solar
Over 70% of the total channel length in all river basins is formed by low order streams, many of which originate on mountaintops. Headwater streams play fundamental roles in processing and transporting terrestrial and aquatic organic matter, often harboring high biodiversity in bottom leaf patches deposited from riparian vegetation. The objective of this study was to assess the variation in taxonomic composition (measured by beta diversity of aquatic macroinvertebrates) among stream sites located in the...

By animal, water, or wind: can dispersal mode predict genetic connectivity in riverine plant species?

Alison Nazareno
Seed dispersal is crucial to gene flow among plant populations. Although the effects of geographic distance and barriers to gene flow are well studied in many systems, it is unclear how seed dispersal mediates gene flow in conjunction with interacting effects of geographic distance and barriers. To test whether distinct seed dispersal modes (i.e. hydrochory, anemochory, and zoochory) have a consistent effect on the level of genetic connectivity (i.e., gene flow) among populations of riverine...

Disentangling the effects of latitudinal and elevational gradients on bee, wasp, and ant diversity in an ancient Neotropical mountain range

Lucas Perillo, Flávio Castro, Ricardo Solar & Frederico Neves
Aim: Ancient tropical mountains are megadiverse, yet little is known about the distribution of their species. We aimed to disentangle the effects of latitudinal and elevational gradients on the distribution of species of Aculeata and to understand the effects of climatic variables across different spatial scales of diversity (α, γ, and β-diversity). Location: Campo rupestre in the Espinhaço Mountain Range, Southeast Brazil. Taxon: Bees, wasps, and ants (Aculeata: Hymenoptera) Methods: We used a unique dataset...

Weather fluctuations are linked to nesting success and renesting decisions in saffron finches

Fernando Marques-Santos, Uschi Wischhoff & Marcos Rodrigues
Life‐histories of neotropical birds seem to vary beyond what is expected according to patterns from northern temperate regions. This variation is well exemplified by saffron finches Sicalis flaveola in subtropical Brazil. They breed for five months on a climate that is relatively warm and rainy throughout the year. Females may attempt from one nest with two eggs up to three nests with five eggs per season. Previous work showed that age and individual quality were...

Web wars: Males of the golden orb-web spider invest more in fights for mated and aggregated females

Amanda Vieira Da Silva, Reisla Oliveira & Paulo Enrique Cardoso Peixoto
In addition to resource value, the cost of finding mates may affect how much males invest in fights for females. The cost of finding females may be imposed through natural factors extrinsic to males, such as female spatial distribution and predation pressure, which can be challenging to simulate in laboratory conditions. Therefore, studies under natural conditions may be suitable for understanding how the costs of finding mating partners affect male investment in fights. We used...

The influence of biogeographical and evolutionary histories on morphological trait-matching and resource specialization in mutualistic hummingbird-plant networks

Bo 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...

Mimosa catherinensis SNP data sets

Alison Nazareno & Thais Martins
To inform management strategies for conservation of Mimosa catharinensis – a narrow endemic, critically endangered plant species – we identified 1,497 unlinked SNP markers derived from a reduced representation sequencing method (i.e., ddRADseq). This set of molecular markers was employed to assess intrapopulation genetic parameters and the demographic history of one extremely small population of M. catharinensis located in the Brazilian Atlantic Forest. We observed a moderate level of genetic diversity for M. catharinensis. Interestingly,...
