1. Regras de Assembleia em aves do Cerrado: estrutura funcional em diferentes escalas espaciais / Assembly rules in Cerrado birds: functional structure at different spatial scales
As comunidades são assembleias de espécies co-ocorrentes que interagem potencialmente umas com as outras. Elas são resultado não apenas de uma série de processos ecológicos ou regras de montagem, mas também de processos evolutivos passados e contínuos. Nos últimos anos, as regras de montagem têm recebido maior atenção dos ecólogos e dois process

3. Assembly rules in Muscid Fly assemblages in the grasslands Biome of Southern Brazil
The distribution of muscid species (Diptera) in grasslands fragments of southern Brazil was assessed using null models according to three assembly rules: (a) negatively-associated distributions; (b) guild proportionality; and (c) constant body-size ratios. We built presence/absence matrices and calculated the C-score index to test negatively-associated distr

4. Impact and regeneration mechanism after invasion by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) in savanna woodland areas, southwestern São Paulo State / Impacto da invasão e mecanismos de regeneração natural do cerradão em áreas ocupadas por Pteridium arachnoideum (kaulf.) Maxon (Dennstaedtiaceae) no sudoeste do Estado de São Paulo
The genus Pteridium comprises bracken species recognized by large fronds and a rhizome system that allows their fast expansion. Bracken presents an elevated biomass production throughout the year, that increases fire occurrence and release chemical compounds that are considered allelopathic. Nowadays, species of the genus Pteridium are well known as problem-

5. Species assembly rules and the biodiversity-ecosystem functioning relationship / Regras entre assemblÃias de espÃcies: relaÃÃo entre biodiversidade e funcionamento do ecossistema
The biological diversity of ecosystems has important implications for their functioning. However, in order for reliable predictions to be made on the effects of species extinctions and/or additions on particular ecosystem functions, accurate knowledge is required on the ways in which species interact. These interactions in turn are important drivers of commu

6. Assembly of avian mixed-species flocks in Amazonia.
Diamond's "assembly rules" model posits that competitive interactions among species govern the composition of avifaunas. Although originally applied to islands in archipelagoes, this controversial set of hypotheses is difficult to test because islands differ in habitat and resource availability, colonization history, and stochastic effects. Permanent mixed-s

7. The assembly and disassembly of ecological networks
Global change has created a severe biodiversity crisis. Species are driven extinct at an increasing rate, and this has the potential to cause further coextinction cascades. The rate and shape of these coextinction cascades depend very much on the structure of the networks of interactions across species. Understanding network structure and how it relates to n

8. The α chain of laminin-1 is independently secreted and drives secretion of its β- and γ-chain partners
A mammalian recombinant strategy was established to dissect rules of basement membrane laminin assembly and secretion. The α-, β-, and γ-chain subunits of laminin-1 were expressed in all combinations, transiently and/or stably, in a near-null background. In the absence of its normal partners, the α chain was secreted as intact protein and protein that ha
