Bridging macroecology and macroevolution in the radiation of sigmodontine rodents

Renan Maestri, André L. Luza, Sandra M. Hartz, Thales R.O. De Freitas & Bruce D. Patterson
Investigations of phenotypic disparity across geography often ignore macroevolutionary processes. As a corollary, the random null expectations to which disparity is compared and interpreted may be unrealistic. We tackle this issue by representing, in geographical space, distinct processes of phenotypic evolution underlying ecological disparity. Under divergent natural selection, assemblages in a given region should have empirical disparity higher than expected under an evolutionarily-oriented null model, while the opposite may indicate constraints on phenotypic evolution. We...

Avaliação do comportamento de vigas de concreto armado reforçadas à flexão com CFRP quando expostas ao intemperismo de distintas regiões climáticas brasileiras e a degradação acelerada

Gláucia Dalfré
Atualmente, vários trabalhos abordam a aplicação de sistemas de reforço com o uso de FRPs (Fiber Reinforced Polymers) em elementos de concreto armado. Entretanto, a grande maioria dos trabalhos são compostos por ensaios de elementos reforçados logo após a cura do adesivo (a qual ocorre com aproximadamente 14 dias), desprezando-se ou negligenciando-se o comportamento a longo prazo desses sistemas de reforço. Além disso, a maioria dos ensaios são realizados em um único ambiente e não...

Geographical variation in the trait-based assembly patterns of multitrophic invertebrate communities

Richardson, Michael C. Melnychuk, Merlijn Jocqué, Jacqueline T. Ngai, Stanislas Talaga, Gustavo C. O. Piccoli … & Régis Céréghino
It has been argued that the mechanisms structuring ecological communities may be more generalizable when based on traits than on species identities. If so, patterns in the assembly of community-level traits along environmental gradients should be similar in different places in the world. Alternatively, geographic change in the species pool and regional variation in climate might result in site-specific relationships between community traits and local environments. These competing hypotheses are particularly untested for animal communities....

Two new species of Miconia s.lat. (Melastomataceae) from Espírito Santo, Brazil

Renato Goldenberg, Lucas F. Bacci, Thuane Bochorny & Marcelo Reginato
We here describe two new species endemic to the state of Espírito Santo, Brazil, that belong to different clades within Miconia s.lat. Miconia quartzicola is presumably part of the Leandra s.str. clade, as indicated by its terminal inflorescences and petals with an acute apex. It has been collected only once in the municipality of Vargem Alta in disturbed vegetation on loose quartzitic substrate (‘morros de sal’). Miconia spiritusanctensis belongs to Miconia sect. Cremanium, as indicated...

Nuanced qualitative trait approaches reveal environmental filtering and phylogenetic constraints on lichen communities

Natalia Koch, Daniel Stanton, Sandra Müller, Leandro Duarte, Adriano Spielmann & Robert Lücking
We propose that a qualitative trait approach based on more detailed nuanced traits may reveal previously overlooked patterns, especially when combined with phylogenetic perspectives. By sampling epiphytic lichens and using a functional approach based on nuanced qualitative traits, such as a much greater resolution over photobiont identity, type of cortex and chemical compounds, we evaluated the effects of environmental filtering and phylogenetic constraints on community assembly along natural succession of Atlantic rainforest. We found changes...
