Host diversity outperforms climate as a global driver of symbiont diversity in the bird-feather mite system

Reginaldo Gusmão, Fabio Hernandes, Mauricio Vancine, Luciano Naka, Jorge Doña & Thiago Gonçalves-Souza
Aim: The simultaneous influence of abiotic and biotic factors as main drivers of global species distributions remains poorly understood, especially in host-dependent groups. In this study, we diverge from traditional macroecological approaches by considering both biotic (avian species diversity) and abiotic (climatic) factors in determining the global distribution pattern of feather mite species richness, one of the most abundant and diverse bird ectosymbionts. Location: Global. Methods: We used a global dataset of feather mite-bird interactions...

Data from: A multilayer network in an herbaceous tropical community reveals multiple roles of floral visitors

Geiza Lima, Ana Virgínia Leite, Camila Souza, Cibele Castro & Elisangela Bezerra
Flower visitation does not necessarily mean pollination. In this sense, floral visitors can either act as mutualists (pollinators) or antagonists (floral robbers/thieves), indicating that these interactions are part of a continuum and that a visitor species can present multiple behaviours. We included both mutualistic and antagonistic interactions between plants and floral visitors in a multilayer network to explore the consequences (at the community level) of the dual roles played by flower visitors. The multilayer network...

Social Solidarity and the Ontological Foundations of Exclusionary Nationalism

C. J. Eland & Nicole L. M. T. de Pontes
This paper seeks to explore the dynamics of contemporary authoritarian populism from a historical perspective, relying on the approaches of Durkheim’s experimental sociology and Levinas’s ethical phenomenology. By reading the works of these two thinkers in concert, a pathology is exposed within this particular form of politics in that the State must necessarily close itself off to the critique of exteriority. Our reading of Durkheim explores the social pathology of nationalism while our reading of...

Nonaggressive behavior: A strategy employed by an obligate nest invader to avoid conflict with its host species

Helder Hugo, Paulo F. Cristaldo & Og DeSouza
In addition to its builders, termite nests are known to house a variety of secondary opportunistic termite species so‐called inquilines, but little is known about the mechanisms governing the maintenance of these symbioses. In a single nest, host and inquiline colonies are likely to engage in conflict due to nestmate discrimination, and an intriguing question is how both species cope with each other in the long term. Evasive behaviour has been suggested as one of...

Data from: Integrating climate and host richness as drivers of global parasite diversity

Paulo M. Martins, Robert Poulin & Thiago Gonçalves-Souza
Aim: Climate and host richness are essential drivers of global gradients in parasite diversity, and the few existing studies on parasites have mostly investigated their effects separately. The advantages of combining these factors into a single analytical framework include unravelling the relative roles of abiotic and biotic drivers of parasite diversity. We compiled a dataset of helminths of amphibians to investigate the direct and indirect effects of temperature seasonality, annual precipitation, precipitation seasonality and host...
