Warming of aquatic ecosystems disrupts aquatic-terrestrial linkages in the tropics

Liam Nash, Pablo Antiqueira, Gustavo Romero, Paula De Omena & Pavel Kratina
Aquatic ecosystems are tightly linked to terrestrial ecosystems by exchanges of resources, which influence species interactions, community dynamics and functioning in both ecosystem types. However, our understanding of how this coupling responds to climate warming is restricted to temperate, boreal, and arctic regions, with limited knowledge from tropical ecosystems. We investigated how warming aquatic ecosystems impacts cross-ecosystem exchanges in the tropics, through the export of aquatic resources into the terrestrial environment and the breakdown of...

Facilitation by isolated trees triggers woody encroachment and a biome shift at the savanna-forest transition

Rodolfo Abreu, Giselda Durigan, Antônio Carlos Melo, Natashi Pilon & William Hoffmann
1. Woody encroachment into grassy biomes is a global phenomenon, often resulting in a nearly complete turnover of species, with savanna specialists being replaced by forest-adapted species. Understanding the mechanisms involved in this change is important for devising strategies for managing savannas. 2. We examined how isolated trees favor woody encroachment and species turnover by overcoming dispersal limitation and environmental filtering. In a savanna released from fire in southeastern Brazil (Cerrado) we sampled woody plants...

Data from: Isotopic niches of tropical birds reduced by anthropogenic impacts: A 100-year perspective

Ana B. Navarro, Marcelo Magioli, Juliano A. Bogoni, Luís F. Silveira, Marcelo Z. Moreira, Eduardo R. Alexandrino, Daniela T. A. Luz, Wesley R. Silva, Marco A. Pizo, Vanessa C. Oliveira & Katia M. P. M. B. Ferraz
The intensification of land use changes in tropical forests during the 20th century, mainly caused by deforestation for agricultural uses, had an overwhelming influence on bird assemblages. However, how these historical anthropogenic changes have impacted the habitat use and diet of tropical birds is poorly known. Stable isotope analysis (δ13C and δ15N) can be useful in this regard since it provides information not only on the habitat and food resource use but also insights on...

LT-Brazil: A database of leaf traits across biomes and vegetation types in Brazil

Eduardo Mariano, Taciana Gomes, Silvia Lins, Adibe Abdalla-Filho, Amin Soltangheisi, Maria Araújo, Rodrigo Almeida, Fernanda Augusto, Luiza Canisares, Siglea Chaves, Cristiane Costa, Thaís Diniz-Reis, Leonardo Galera, Melissa Martinez, Maristela Morais, Elen Perez, Lucas Reis, Carla Simon, Silvia Mardegan, Tomas Domingues, Raquel Miatto, Rafael Oliveira, Carla Reis, Gabriela Nardoto, Jens Kattge … & Luiz Martinelli
Motivation: Leaf traits represent an important component of plant functional strategies, and those related to carbon fixation and nutrient acquisition form the leaf economics spectrum. However, observations of functional leaf traits are underrepresented in tropical regions in comparison with those in temperate areas. Brazil, a country with continental scale and vast biodiversity is a timely example, where many biomes are impacted by human activities and climate change. However, leaf traits relevant to understand vegetation responses...

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...

Warming and top predator loss drive direct and indirect effects on multiple trophic groups within and across ecosystems

Pablo Antiqueira, Owen Petchey, Felipe Rezende, Luiz Felipe Velho, Luzia Rodrigues & Gustavo Romero
1. The interspecific interactions within and between adjacent ecosystems strongly depend on the changes in their abiotic and biotic components. However, little is known about how climate change and biodiversity loss in a specific ecosystem can impact the multiple trophic interactions of different biological groups within and across ecosystems. 2. We used natural micro-ecosystems (tank-bromeliads) as a model system to investigate the main and interactive effects of aquatic warming and aquatic top predator loss (i.e.,...

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...

Ravnoor S Gill, Hyo M Lee, Benoit Caldairou, Seok-Jun Hong, Carmen Barba, Francesco Deleo, Ludovico D’Incerti, Vanessa C Mendes Coelho, Matteo Lenge, Mira Semmelroch, Dewi Schrader, Fabrice Bartolomei, Maxime Guye, Andreas Schulze-Bonhage, Horst Urbach, Kyoo Ho Cho, Fernando Cendes, Renzo Guerrini, Graeme Jackson, R Edward Hogan, Neda Bernasconi & Andrea Bernasconi
Objective. To test the hypothesis that a multicenter-validated computer deep learning algorithm detects MRI-negative focal cortical dysplasia (FCD). Methods. We used clinically acquired 3D T1-weighted and 3D FLAIR MRI of 148 patients (median age, 23 years [range, 2-55]; 47% female) with histologically verified FCD at nine centers to train a deep convolutional neural network (CNN) classifier. Images were initially deemed as MRI-negative in 51% of cases, in whom intracranial EEG determined the focus. For risk...

Hydraulic prediction of drought-induced plant dieback and top-kill depends on leaf habit and growth form

Ya-Jun Chen, Brendan Choat, Frank Sterck, Phisamai Maenpuen, Masatoshi Katabuchi, Shu-Bin Zhang, Kyle Tomlinson, Rafael Oliveira, Yong-Jiang Zhang, Kun-Fang Cao & Steven Jansen
Hydraulic failure caused by severe drought contributes to aboveground dieback and whole-plant death. The extent to which dieback or whole-plant death can be predicted by plant hydraulic traits has rarely been tested among species with different leaf habits and/or growth forms. We investigated 19 hydraulic traits in 40 woody species in a tropical savanna and their potential correlations with drought response during an extreme drought event during the El Niño–Southern Oscillation in 2015. Plant hydraulic...

Semi-directed interviews with pregnant teenagers who access primary health services in Southeastern Brazil: a clinical-qualitative study.

PAULA ORTOLAN
The adolescent population is considered vulnerable in aspects related to reproduction and, therefore, teenage pregnancy and its consequences represent a public health problem in several countries. In these countries, the barriers and facilitators reported on family relations and sexuality by pregnant adolescents in vulnerable situations can be factors that threaten the health of pregnant adolescents. The perception of adolescents who become pregnant generates fundamental data to meet the needs of this vulnerable group. This study...

Marcas epigenéticas potencialmente responsivas à ação do valproato de sódio (VPA) na heterocromatina de Triatoma infestans (Klug)

Douglas Silva Dos Santos
As células somáticas de Triatoma infestans, hemíptero hematófago e vetor da doença de Chagas, são caracterizadas pela presença de corpos heterocromáticos (cromocentros) cujo DNA é rico em bases AT. Neste inseto, o tratamento com valproato de sódio/ácido valproico (VPA), conhecido inibidor de deacetilases de histonas, promove remodelação cromatínica nos cromocentros, porém, diferindo de respostas usuais a essa droga, esta não se mostra acompanhada por acetilação de H3K9 e H4K8. Também se desconhece se o VPA...

Desvendando mecanismos de coexistência em aranhas: uma abordagem multidimensional

German Villanueva
Investigar os mecanismos responsáveis pela coexistência de espécies congenéricas com nichos semelhantes tem sido um dos grandes desafios de pesquisas ecológicas. Entretanto, até o momento poucos estudos sobre coexistência abordaram simultaneamente as três principais dimensões do nicho (temporal, espacial e trófico), o que limita tanto o poder preditivo das conclusões obtidas, quanto a possibilidade de comparação dos resultados entre diferentes estudos. Registramos recentemente sete espécies congenéricas de aranhas construtoras de teias tridimensionais (Cryptachaea, Theridiidae) ocorrendo...
