Post ESCRITO POR Tiago Olivoto

This post is also available in English

Em nosso recente artigo na Methods in Ecology and Evolution, Alessandro D. Lúcio e eu descrevemos um novo pacote R para análise de ensaios multi-ambientes chamado metan. Ensaios multi-ambientes são um tipo de ensaio em programas de melhoramento de plantas, onde vários genótipos são avaliados em um conjunto de ambientes. A análise desses dados requer a combinação de várias abordagens, incluindo manipulação, visualização e modelagem de dados. A versão estável mais recente do metan (v1.5.1) está disponível agora no repositório CRAN. Então, pensei em compartilhar a história da minha primeira incursão no uso do R criando um pacote e submetendo um artigo para uma revista que nunca havia submetido antes.

Today we bring the first part of an interview with Dennis Murray and Brett Sandercock about their brand new book in population ecology methods: “Population Ecology in Practice.” The editors were kind enough to share some interesting backstage information with us.

Population Ecology in Practice introduces a synthesis of analytical and modelling approaches currently used in demographic, genetic, and spatial analyses. Chapters provide examples based on real datasets together with a companion website with study cases and exercises implemented in the R statistical programming language.

Stay tuned for the second part of this interview, where we talk about some of the challenges of editing a large book and the editors share essential advice for anyone looking into leading such a project!

Dance has been part of human culture for millennia. Some scholars refer to dance as a specific language, dependent on the space and time in which it exists and dependent on the power structures that rule in that time. April 29th marks International Dance Day; a day initiated in 1982 by the International Dance Committee of the UNESCO International Theatre Institute to commemorate the birthday of Jean-Georges Noverre, a distinguished French choreographer.

For humans, dance is considered a sacred ritual, sometimes a form of communication and sometimes an important social and courtship activity. A recent study has even linked the innate ability to dance with greater survival rates in prehistoric times. However, for certain species of wild animal, dance-like behaviours are crucial for communication and mating. In this blog, I am going to highlight the evolutionary foundations of dance in wild animals and explore some of the ways that dance is used in ecology.
