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...

Ecological mechanisms explaining interactions within plant-hummingbird networks: morphological matching increases towards lower latitudes

Simmons, Boris Tinoco, Isabela G. Varassin, Marcelo F. Vasconcelos, Bob O’Hara … & Bo Dalsgaard
Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap, and species abundances. How these mechanisms explain interaction frequencies across environmental gradients remains poorly understood. Consequently, we also know little about the mechanisms that drive the geographical patterns in network structure, such as complementary specialization and modularity. Here, we use data on morphologies, phenologies and abundances to explain interaction frequencies between hummingbirds and plants at a large geographic scale. For...

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...

Four raised to one equals one: a genetic approach to the Pseudolaelia vellozicola complex does not follow a math rule

Alison Nazareno, Luiz Menini Neto, Renata Buzatti, Cássio Van Den Berg & Rafaela Forzza
Pseudolaelia is a genus endemic to the eastern Brazilian Atlantic Forest, consisting of 12 accepted species. Some Pseudolaelia species, such as P. vellozicola, P. aguadocensis, P. oliveirana and P. regentii, referred to here as the PV complex, present extensive intra- and interpopulation morphological polymorphism, raising uncertainty regarding their circumscriptions. Although previous morphological analyses were used to solve the generic boundaries in the PV complex, persuasive genetic evidence is lacking. In order to test the hypothesis...
