Scale-dependent shifts in functional and phylogenetic structure of Mediterranean island plant communities over two centuries

Chunhui Zhang, Marc William Cadotte, Alessandro Chiarucci, Michel Loreau, Charles Willis, Xingfeng Si, Lanping Li & Marcus Cianciaruso
1. Since the Industrial Revolution, the rapid global population and economic expansion has had tremendous impacts on biodiversity across spatial scales, especially for islands. While changes in species richness are easily inferred, the impact of human activity on the underlying community assembly processes has been difficult to ascertain because of lack of long-term community data. 2. Here, we document how the manifestations of plant community assembly have changed over time and space in a Mediterranean...

Landscape structure and local variables affect plant community

Juliana Silveira Dos Santos, Carlos M. Silva-Neto, Thiago Castro Silva, Karoline Nascimento Siqueira, Milton Cezar Ribeiro & Rosane Collevatti
The biodiversity in agricultural landscapes depends on land-use types, natural elements, and farming intensity. The Brazilian Cerrado is a biodiversity hotspot, however, the native vegetation loss rates have increased in the last years, leading several plant species to extinction risk. Here, we analyze the effects of local (soil fertility and litter amount) and landscape variables (patch shape, habitat amount, compositional heterogeneity, matrix dominance and connectivity) on alpha species richness and diversity, and basal area of...

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...

Quantitative genetics of extreme insular dwarfing: the case of red deer (Cervus elaphus) on Jersey

José Alexandre Felizola Diniz-Filho, Ana Santos, Elisa Barreto, Felipe Naves, Wanderson Santos, Kelly Souza, Rejane Santos-Silva, Ricardo Dobrovolski, Thannya Soares, Rosana Tidon, Zander Spigoloni, Thiago Rangel, Pasquale Raia, Joaquín Hortal & Lucas Jardim
Aim: The Island Rule – i.e. the tendency for body size to decrease in large mammals and increase in small mammals on islands has been commonly evaluated through macroecological or macroevolutionary, pattern-orientated approaches, which generally fail to model the microevolutionary processes driving either dwarfing or gigantism. Here, we seek to identify which microevolutionary process could have driven extreme insular dwarfism in the extinct dwarf red deer population on the island of Jersey. Location: Jersey, UK...

Positive forest cover effects on coffee yields are consistent across regions

Adrian González-Chaves, Luísa Carvalheiro, Lucas Garibaldi & Jean Paul Metzger
1. Enhancing biodiversity-based ecosystem services can generate win-win opportunities for conservation and agricultural production. Pollination and pest control are two essential agricultural services provided by mobile organisms, many depending on native vegetation networks beyond the farm scale. Many studies have evaluated the effects of landscape changes on such services at small scales. However, several landscape management policies (e.g., selection of conservation sites) and associated funding allocation occur at much larger spatial scales (e.g., state or...

Temporal changes in the potential geographic distribution of Histiotus velatus (Chiroptera, Vespertilionidae), the “decade effect\"

Liriann Chrisley Da Silva, Rafaela Almeida, Pablo Henrique Da Silva, Monik Oprea, Poliana Mendes, Daniel Brito & Thiago Vieira
Also investigate how the potential distribution of this species changes with the addition of new records over the decades (decade effect). Assuming that (1: hypothesis of the effect of the decade) the addition of new occurrence records over time increases the potential size of the species distribution; and (2: Wallacean distance hypothesis) over the years, the new points added are increasingly distant from the research centers. Considering the geographic knowledge gap of Histiotu velatus, our...

Influência da inserção de fibra de polietileno (Wallpapering Technique) na tensão de contração de polimerização, deformação de cúspide e resistência à fratura em molares restaurados com diferentes resinas compostas

Gabrielly D'Paula Muniz Barbosa
Uma odontologia biomimética reabilita uma estrutura dental perdida buscando máxima conservação de estrutura dental. As fibras de polietileno de ultra / alto peso molecular (Ribbond), têm sido aplicadas em uma técnica denominada Técnica de Wallpapering. A literatura também denomina a técnica como “stress - free- restaurações”. Atualmente, não há evidência de que a inserção do Ribbond nas paredes do preparo cavitário seja capaz de diminuir a tensão de contração de polimerização e a deformação de...

MODELO INFORMACIONAL PARA IDENTIFICAÇÃO PRECOCE DAS LESÕES POTENCIALMENTE MALIGNAS DE LÁBIO E CAVIDADE ORAL (DBPM)

Suse Castilho
O Modelo Informacional é uma representação conceitual e canônica, onde os elementos referentes a um documento específico são modelados em seções e blocos de dados, com seus respectivos tipos de dados a serem informados. Também são informadas as referências para o uso de recursos terminológicos." (BRASIL, 2020). O objetivo do presente trabalho é construir um Modelo Informacional que subsidiará o desenvolvimento de ferramenta computacional de apoio à atenção primária em saúde (APS) para o referenciamento...

COVID-19: EFEITOS NA SAÚDE MENTAL DOS PROFISSIONAIS DA ATENÇÃO PRIMÁRIA

Flávio Henrique Rodrigues Da Silva
INTRODUÇÃO: A pandemia de infecção pelo COVID-19 teve início na província de Wuhan de Hubei, na China, no final de 2019, tomou proporções catastróficas como doença com sintomas respiratórios com grande poder de contaminação e transmissão. Uma equipe multiprofissional de cuidados com pacientes suspeitos ou infectados para o COVID- 19 é altamente exposta devido ao contato com substâncias infecciosas advindas nesses pacientes. A quantidade alarmante de profissionais infectados nessas equipes tem aumentado progressivamente, o que...
