Competition and phylogeny determine community structure in Mullerian co-mimics

Until recently, the study of negative and antagonistic interactions (for example, competition and predation) has dominated our understanding of community structure, maintenance and assembly(1). Nevertheless, a recent theoretical model suggests that positive interactions (for example, mutualisms) may counterbalance competition, facilitating long-term coexistence even among ecologically undifferentiated species(2). Mullerian mimics are mutualists that share the costs of predator education(3) and are therefore ideally suited for the investigation of positive and negative interactions in community dynamics. The sole empirical test of this model in a Mullerian mimetic community supports the prediction that positive interactions outweigh the negative effects of spatial overlap(4) (without quantifying resource acquisition). Understanding the role of trophic niche partitioning in facilitating the evolution and stability of Mullerian mimetic communities is now of critical importance, but has yet to be formally investigated. Here we show that resource partitioning and phylogeny determine community structure and outweigh the positive effects of Mullerian mimicry in a species-rich group of neotropical catfishes. From multiple, independent reproductively isolated allopatric communities displaying convergently evolved colour patterns, 92% consist of species that do not compete for resources. Significant differences in phylogenetically conserved traits (snout morphology and body size) were consistently linked to trait-specific resource acquisition. Thus, we report the first evidence, to our knowledge, that competition for trophic resources and phylogeny are pivotal factors in the stable evolution of Mullerian mimicry rings. More generally, our work demonstrates that competition for resources is likely to have a dominant role in the structuring of communities that are simultaneously subject to the effects of both positive and negative interactions.

Medicinal plants used by "Passo da Ilha" rural community in the city of Pato Branco, southern Brazil

O objetivo deste trabalho foi resgatar e documentar o conhecimento popular referente às plantas medicinais utilizadas na comunidade rural do Passo da Ilha, em Pato Branco-PR (26° 11' S, 52°36' W e 760 m de altitude). Optou-se por utilizar o modelo de entrevista estruturada com 16 informantes, os quais possuíam o conhecimento sobre o uso das plantas medicinais em suas famílias. O período da realização das entrevistas foi de outubro a dezembro de 2000. As plantas foram coletadas no campo, identificadas e vouchers foram depositados no Herbário Irina Delanova de Gemtchjnicov (BOTU) da Universidade Estadual Paulista, em Botucatu-SP. Foram identificadas 47 famílias botânicas e 114 espécies de plantas medicinais. Estas plantas foram indicadas para mais de 30 usos medicinais diferentes. A comunidade é composta na maioria por descendentes de europeus, justificando a presença de muitas plantas exóticas. O domínio do uso das plantas é feminino, porém o conhecimento é menor nas gerações mais novas, denotando um processo de erosão cultural.

The WIPO development agenda and the contribution of the international library community

Purpose - The purpose of this paper is to analyze the international strengthening of copyright law in developing countries and the active involvement of the international library community in the movement against it.Design/methodology/approach - The paper describes the overprotection of intellectual property rights through international and bilateral treaties, the reaction against such through the proposal of a WIPO development agenda, and the contribution of the international library organizations to the debates and discussions in the WIPO arena.Findings - The initiative for a development agenda for WIPO has proven much more successful than many had imagined, even its promoters. The most relevant proposals made by the international library community were included in the final list of approved recommendations.Originality/value - The paper raises awareness of the relationship between copyright and access to knowledge and, in consequence, the need for library organizations to exert influence in such legislation.

The nematode community in the Atlantic rainforest lizard Enyalius perditus Jackson, from south-eastern Brazil

Studies focusing on communities of helminths from Brazilian lizards are increasing, but there are many blanks in the knowledge of parasitic fauna of wild fauna. This lack of knowledge hampers understanding of ecological and parasitological aspects of involved species. Moreover, the majority of research has focused on parasitic fauna of lizards from families Tropiduridae and Scincidae. Only a few studies have looked at lizards from the family Leiosauridae, including some species of Enyalius. This study presents data on the gastrointestinal parasite fauna of Enyalius perditus and their relationships with ecological aspects of hosts in a disturbed Atlantic rainforest area in the state of Minas Gerais, south-eastern Brazil. Two nematode species, Oswaldocruzia burseyi [(Molineidae) and Strongyluris oscari (Heterakidae) were found. Nematode species showed an aggregated distribution in this host population, with O. burseyi being more aggregated than S. oscari. The present study extends the range of occurrence of O. burseyi to the Brazilian continental area. © 2011 Cambridge University Press.

Theoretical Referents in Knowledge Organization: A Domain Analysis of the Knowledge Organization Journal

Aiming at contributing to the epistemological characterization of the area of knowledge organization, our goal is to analyze the KO journal, since its creation in 1993, as a knowledge domain, from a nuclear community of the most productive and greater impact authors, analyzing the dialogue among citing authors and cited ones, and also the co-citations established by the citing authors. We worked with a corpus of 310 articles published between 1993 and 2011 produced by a total of 360 authors. The relatively more productive authors, a group geographically concentrated in Europe (37%), North America (44%) and Asia (19%), is clearly explained by the historical European origin of the ISKO and by an increasing North American presence along the years. Of the 33 most cited authors, 22 were co-cited in at least 6 works, which suggests that they are the theoretical referential nucleus of the area, in the studied journal. Finally, we observe that the area reveals theme cohesion and coherence in its production, enabling us to clearly visualize its theoretical referential nucleus and to confirm the role performed by the KO magazine as a catalyzing agent of international theoretical construction in the area.

Knowledge of professionals from public service on oral health promotion for babies

Health promotion seeks to integrate oral health practices to other public health, by building healthy public policy and the development of strategies directed to all people in the community. This study aimed to analyze the knowledge and actions on the infants’ oral health promotion by dentists, pediatricians and nurses. Were interviewed dentists (n=34), pediatricians (n=31) and nurses (n=26) from Basic Health Units, Family Health Units and Centers for Education and Recreation in Araraquara - SP about knowledge and actions on oral health promotion for infants, by filling out a pre-tested questionnaire. Data were analyzed by association tests. Generally, the professionals are aware of and perform actions on oral health promotion for infants. Most participants were female; mean age of 39.9 years, worked in Basic Health Units, had over 10 years of graduation, demonstrated knowledge on and considered oral health promotion in infants very important. The time since graduation and actions on oral health promotion for infants were associated (p<0.05) with issues concerning the use of dental floss. That most of the professionals who participated in this study know about, take actions on oral health promotion for infants and consider them crucial.
