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...

Data from: Evolution of dispersal, habit, and pollination in Africa pushed Apocynaceae diversification after the Eocene-Oligocene climate transition

Nicolai M. Nürk, Cássia Bitencourt, Alessandro Rapini, Mark Fishbein, André O. Simões, David J. Middleton, Ulrich Meve, Mary E. Endress & Sigrid Liede-Schumann
Apocynaceae (the dogbane and milkweed family) is one of the ten largest flowering plant families, with approximately 5,350 species and diverse morphology and ecology, ranging from large trees and lianas that are emblematic of tropical rainforests, to herbs in temperate grasslands, to succulents in dry, open landscapes, and to vines in a wide variety of habitats. Despite a specialized and conservative basic floral architecture, Apocynaceae are hyperdiverse in flower size, corolla shape, and especially derived...

Bat-flower interaction networks in Caatinga reveal generalized associations and temporal stability

Eugenia Cordero-Schmidt, Pietro Kiyoshi Maruyama, Juan Carlos Vargas-Mena, Paulino Pereira Oliveira, Francisco De Assis R. Santos, Rodrigo A. Medellín, Bernal Rodriguez-Herrera & Eduardo M. Venticinque
Seasonal variation in precipitation regimes influences species composition and plant-animal interactions. Such temporal variation is especially relevant in the Brazilian Caatinga, the largest Seasonally Dry Tropical Forest in South America, where bat pollination is unusually frequent in comparison with other tropical plant communities. Here, we describe seasonal and annual variations of the interaction networks between nectarivorous bats and flower species in the Caatinga. Five species of nectar-feeding bats interacted with 30 plant species. Nectarivorous bats...

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...

Data from: Tricky Morphology: A new species of Chamaecrista (Leguminosae) shows strong morphological convergence among not closely related species found in similar habitat

Matheus Martins Teixeira Cota, Juliana Gastaldello Rando, Cristiane Snak & Luciano Paganucci De Queiroz
Plants from Brazilian campos rupestres usually present morphological strategies that allow them to survive in extreme environments. However, in Chamaecrista (Leguminosae, Caesalpinioideae), one of the most diverse genera in the campos rupestres, needle-like leaflets are rare. Reviewing the species that present such leaf morphology, we describe Chamaecrista acicularis, a new species, from the Canastra Range, in the southwestern region of the state of Minas Gerais, Brazil. Phylogenetic analyses revealed that C. acicularis is not closely...
