Premise of the Study: New sequencing technologies enable the possibility of generating large-scale molecular datasets for constructing the plant tree of life. We describe a new probe set for target enrichment sequencing to generate nuclear sequence data to build phylogenetic trees with any flagellate land plants, including hornworts, liverworts, mosses, lycophytes, ferns, and all gymnosperms. Methods and Results: We leveraged existing transcriptome and genome sequence data to design a set of 56,989 probes for target...

Head and mandible shapes are highly integrated yet represent two distinct modules within and among worker sub-castes of the ant genus Pheidole

Alexandre Casadei Ferreira, Nicholas R. Friedman, Evan Economo, Marcio Pie & Rodrigo Feitosa
Ants use their mandibles for a wide variety of tasks related to substrate manipulation, brood transport, food processing, and colony defence. Due to constraints involved in colony upkeep, ants evolved a remarkable diversity of mandibular forms, often related to specific roles such as specialized hunting and seed milling. Considering these varied functional demands, we focused on understanding how the mandible and head shape vary within and between Pheidole sub-castes. Using x-ray microtomography and 3D geometric...

Acaulescence promotes speciation and shapes the distribution patterns of palms in Neotropical seasonally dry habitats

Cibele Cássia-Silva, Rafael Silva Oliveira, Lílian P. Sales, Cíntia G. Freitas, Lucas Jardim, Thaíse Emilio, Christine D. Bacon & Rosane G. Collevatti
Rainforests have been a source of lineages to open and seasonally dry habitats throughout Angiosperm evolution, especially in the Neotropics. However, the underlying mechanisms that allow such shifts remain poorly understood at large spatial scales. Here, we test whether acaulescence (an underground stem or a very short stem concealed in the ground) has affected the colonization and speciation in Neotropical seasonally dry habitats by cocosoid palms (Cocoseae). Acaulescent species maintain their growth underground, which increases...

Segalla, Thibaud Decaëns, Herlon S. Nadolny, Clara P. Peña‐Venegas, Cláudia M. B. F. Maia, Amarildo Pasini … & George G. Brown
Amazonian rainforests once thought to hold an innate pristine wilderness, are increasingly known to have been densely inhabited by populations showing a diverse and complex cultural background prior to European arrival. To what extent these societies impacted their landscape is unclear. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies as a result of more sedentary habits. Much is known of the chemistry of these soils, yet their...

Phylogeny and character evolution of the neotropical fern genus Cyclodium (Dryopteridaceae)

Amabily Bohn, Alan R. Smith, Fernando B. Matos, Robbin C. Moran & Paulo H. Labiak
Cyclodium is a neotropical fern genus with 13 species, most of them distributed in the Amazonian lowlands, particularly in the Guianan region and along the border with the Andes. It belongs to the polybotryoid clade of Dryopteridaceae, being unique within this clade by a combination of characters related to rhizome growth, leaf dimorphism, anastomosing venation, and peltate indusia. Here we present a molecular phylogenetic hypothesis for Cyclodium resulting from Bayesian and Maximum Likelihood analyses, using...

Mullerian mimicry and the colouration patterns of sympatric coral snakes

Renan Bosque, Chaz Hyseni, Maria Luiza Gonçalves Santos, Eduardo Rangel, Camila Juliana Da Silva Dias, Jacob Hearin, , Fabricius Maia, Guarino Colli & Brice Noonan
This dataset cointains data used for the study of Müllerian mimicry in coral snakes. Coral snakes in the genus Micrurus are venomous, aposematic organisms that signal danger to predators through vivid colouration. Previous studies found that they serve as models to several harmless species of Batesian mimics. However, the extent to which Micrurus species engage in Müllerian mimicry remains poorly understood. We integrate detailed morphological and geographical distribution data to investigate if coral snakes are...

Ants of the State of Pará, Brazil: a historical and comprehensive dataset of a key biodiversity hotspot in the Amazon Basin

Emília Zoppas De Albuquerque, Lívia Pires Do Prado, Joudellys Andrade-Silva, Emely Laira Silva De Siqueira, Kelly Liane Da Silva Sampaio, Diego Alves, Carlos Roberto F. Brandão, Paloma L.

Silva
The state of Pará in northern Brazil is located entirely within the Amazon Basin and harbors a great diversity of landscape and vegetation types that support high levels of biodiversity. Here, we provide a comprehensive inventory of ant species and their distribution in Pará. This regional list is based on an extensive review of species records from published and unpublished sources covering a period of 134 years (1886–2020) and includes the five most representative ant...

Continuous bite monitoring method (GPEP)

Anderson Michel Soares Bolzan, Szymczak, Nadin, Olivier Bonnet, Marcelo Wallau, Anibal De Moraes, Renata Moraes, Alda Monteiro & Paulo Carvalho
Determining herbage intake is pivotal for studies on grazing ecology. Direct observation of animals allows describing the interactions of animals with the pastoral environment along the complex grazing process. The objectives of the study were to evaluate the reliability of the continuous bite monitoring (CBM) method in determining herbage intake in grazing sheep compared to the standard double-weighing technique (DW) method during 45-min feeding bouts; evaluate the degree of agreement between the two techniques; and...

Data for: Phylogenomic analyses reveal non-monophyly of the antbird genera Herpsilochmus and Sakesphorus (Thamnophilidae), with description of a new genus for Herpsilochmus sellowi

Gustavo Bravo, Bret Whitney, Ricardo Belmonte-Lopes, Marcos Bornschein, Natalia Aristizabal, Renata Beco, Jaqueline Battilana, Luciano Naka, Alexandre Aleixo, Marcio Pie, Luis Silveira, Elizabeth Derryberry & Robb Brumfield
The family Thamnophilidae is a species-rich Neotropical radiation of passerine birds. Current classification of its 235 species is mostly based on morphological similarities, but recent studies integrating comprehensive phenotypic and phylogenetic data have redefined taxonomic limits of several taxa. Here, we assess generic relationships of Herpsilochmus, Sakesphorus, Thamnophilus, Biatas, and Dysithamnus using DNA sequences from the mitochondrion, nuclear exons, and ultraconserved elements (UCEs), with further attention to interspecific relationships within Herpsilochmus. We show that Herpsilochmus...

A new phylogenetic hypothesis for Cereinae (Cactaceae) points to a monophyletic subtribe

Mariana Ramos Fantinati, Patricia Soffiatti & Alice Calvente
Cereinae comprises 14 genera distributed in Neotropical dry forest formations such as in the Caatingas of Northeastern or in rocky outcrops in the north of Southeastern Brazil. Historically, the taxonomy of the group has been very controversial, especially regarding generic circumscriptions, and phylogenetic relationships within the group are still poorly understood. To investigate the delimitation of the subtribe and infra-subtribal relationships, we performed a phylogenetic analysis including 50 taxa representing 13 genera using one nuclear...

Why signal if you are not attractive? Courtship synchrony in a fiddler crab

Lauren Harrison, Gabriela Melo, Daniela Perez & Patricia Backwell
Synchronised male courtship signals are puzzling because males generally compete with each other for females. Male Austruca mjoebergi fiddler crabs wave in synchrony to attract females, but, all else being equal, females have a strong preference for ‘leader’ males that can produce waves before other males (‘followers’). So why do followers participate in synchrony? Here, we experimentally investigate three explanations for why followers might wave in synchrony: 1) followers obtain a small proportion of matings,...

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...

High tree diversity enhances light interception in tropical forests

Marina Melo Duarte, Caroline Isaac Ferreira Zuim, Taísi Bech Sorrini, Luís Eduardo Bernardini, Rafael De Andrade Moral, Joannes Guillemot, Catherine Potvin, Wagner Hugo Bonat, José Luiz Stape & Pedro Henrique Santin Brancalion
We used two forest plantation experiments, the Sardinilla site in Panama (containing monocultures, 2-, 3- and 5-species mixtures in the main plantation, established in 2001, and 6-, 9- and18-species mixtures in the high-diversity plantation, established in 2003), and the Anhembi site in Brazil (established in 2006, containing 20-, 58- and 114-species mixtures), to investigate the effects of forest tree richness on the amount and distribution (horizontal, vertical and temporal) of intercepted ligh (red:far-red ratio -...
