Body size mediates life history, physiology, and inter- and intra-specific interactions. Within species, sexes frequently differ in size, reflecting divergent selective pressures and/or constraints. Both sexual selection and differences in environmentally-mediated reproductive constraints can drive sexual size dimorphism, but empirically testing causes of dimorphism is challenging. Manakins (Pipridae), a family of Neotropical birds comprising ~50 species, exhibit both male- and female-biased size dimorphism and are distributed across gradients of precipitation and elevation. Males perform courtship...

Data from: Biogeography of curimatid fishes reveals multiple lowland-upland river transitions and differential diversification in the Neotropics (Teleostei, Curimatidae)

Bruno F. Melo, James S. Albert, Fernando C. P. Dagosta & Victor A. Tagliacollo
The Neotropics harbors a megadiverse ichthyofauna comprising over 6300 species with approximately 80% in just three taxonomic orders within the clade Characiphysi. This highly diverse group has evolved in tropical South America over tens to hundreds of millions of years influenced mostly by re‐arrangements of river drainages in lowland and upland systems. In this study, we investigate patterns of spatial diversification in Neotropical freshwater fishes in the family Curimatidae, a species‐rich clade of the order...

Dataset for: Short flowers for long tongues: functional specialization in a nocturnal pollination network of an asclepiad in long-tongued hawkmoths (Biotropica)

Felipe W. Amorim, Salvador Marino, Priscila Andre Sanz-Veiga, Jeff Ollerton & Paulo E. Oliveira
Since Darwin, very long and narrow floral tubes have been known to represent the main floral morphological feature for specialized long-tongued hawkmoth pollination. However, specialization may be driven by other contrivances instead of floral tube morphology. Asclepiads are plants with a complex floral morphology where primary hawkmoth pollination had never been described. We detailed here the intricate pollination mechanism of the South American asclepiad Schubertia grandiflora, where functional specialization on long-tongued hawkmoth pollinators occurs despite...

Agronomic potential of BC1F2 populations of Santa Cruz dwarf tomato plants

Danilo Araújo Gomes, Gabriel Mascarenhas Maciel, Luiz Brandão Neto, Camila Soares de Oliveira, Ana Carolina Silva Siquieroli & Rafael Resende Finzi
ABSTRACT. The use of dwarf lines to obtain mini-tomato hybrid plants has led to agronomic and economic advantages. However, the benefits provided by dwarf parents in tomato hybrids of the Santa Cruz type remain unexplored. The aims of this study were to determine the agronomic enhancement in BC1F2 dwarf populations bearing characteristic fruit of the Santa Cruz type after the first backcross and to select populations with high agronomic potential and fruit quality. The experiment...

Selection of biofortified mini lettuce progenies resistant to Pectobacterium carotovorum subsp. carotovorum

Ana Carolina Pires Jacinto, Renata Castoldi, Isadora Gonçalves da Silva, Diesiele Caroline Silveira Mota, Leticia Gonçalves Moreira, Nilvanira Donizete Tebaldi, Hamilton César de Oliveira Charlo & Gabriel Mascarenhas Maciel
ABSTRACT. Brazilian consumers are increasingly seeking unique vegetable products, such as mini lettuces. However, their production is hampered by a wide variety of pathogens, including Pectobacterium carotovorum subsp. carotovorum, which causes soft rot in lettuce. In this study, we aimed to select biofortified mini lettuce genotypes with good agronomic traits and resistance to P. carotovorum. A randomized block design consisting of 12 treatments, conducted in a field and greenhouse (Federal University of Uberlândia [UFU]), was...

Abstract Objectives To evaluate the disease activity before and after COVID-19 and risk factors associated with outcomes, including hospitalization, intensive care unit (ICU) admission, mechanical ventilation (MV) and death in patients with spondylarthritis (SpA). Methods ReumaCoV Brazil is a multicenter prospective cohort of immune-mediated rheumatic diseases (IMRD) patients with COVID-19 (case group), compared to a control group of IMRD patients without COVID-19. SpA patients enrolled were grouped as axial SpA (axSpA), psoriatic arthritis (PsA) and...

Reduced visitation to buzz-pollinated Cyanella hyacinthoides in the presence of other pollen sources in the hyperdiverse Cape Floristic Region

Jurene Kemp, Francismeire Telles & Mario Vallejo-Marin
Many plant species have floral morphologies that restrict access to floral resources, such as pollen or nectar, and only a subset of floral visitors can perform the handling behaviours required to extract restricted resources. Due to the time and energy required to extract resources from morphologically complex flowers, these plant species potentially compete for pollinators with co-flowering plants that have more easily accessible resources. A widespread floral mechanism restricting access to pollen is the presence...

Genetic dissimilarity for thermoinhibition in seeds of lettuce lines after defoliation

Hugo Cesar Rodrigues Moreira Catão, Gabriel Mascarenhas Maciel, Luiz Antonio Augusto Gomes, Ana Carolina Silva Siquieroli, José Magno Queiroz Luz & Luciano Dias Cabral Neto
ABSTRACT. Removal of lettuce basal leaves is a technique used by the seed industry; however, the effects on seed production and physiological potential are unknown. Genetic dissimilarity is fundamental in the identification of individuals in terms of traits of interest, although it is rarely considered in relation to seeds that are tolerant to thermoinhibition. The aim of this study was to ascertain the relationship between defoliation of lettuce plants and seed yield/physiological quality, as well...

Integrating nocturnal and diurnal interactions in a Neotropical pollination network

Camila Souza, Paulo Oliveira, Bianca Rosa & Pietro Maruyama
Plants establish pollination interactions with different groups of animals, including nocturnal ones that establish interactions with economically valuable and culturally important crops, as well as wild plants of conservation concern. Despite the considerable number of studies addressing the structure and dynamic of pollination networks, nocturnal interactions have been relatively overlooked. Using a multilayer network approach and considering diurnal and nocturnal interactions, we aimed to understand how interactions at different periods of the day are integrated...

Haemosporidian parasites and incubation period influence plumage coloration in tanagers (Passeriformes: Thraupidae)

Victor Aguiar De Souza Penha, Fabricius Maia, Alan Fecchio, Jeffrey Bell, Jason Weckstein, Robert Ricklefs, Erika Martins Braga, Patrícia De Abreu Moreira, Leticia Soares, Steven Latta, Graziela Tolesano-Pascoli, Renata Alquezar, Kleber Del Claro & Lilian Manica
Birds are visually oriented and use their plumage coloration as an important signaling trait in social communication. Males and females may have different patterns of plumage coloration, a phenomenon known as sexual dichromatism. Because males tend to have more complex plumages, sexual dichromatism is usually attributed to female choice. However, plumage coloration is partly condition-dependent, therefore other selective pressures affecting individuals’ success may also drive the evolution of this trait. Here we used tanagers to...
