Stable correlation structure among multiple plumage colour traits: can they work as a single signal?

S-29.3: Plumage coloration as a signal of social status

Senar, J.C. 1999. Plumage colouration as a signal of social status. In: Adams, N.J. & Slotow, R.H. (eds) Proc. 22 Int. Ornithol. Congr., Durban: 1669-1686. Johannesburg: BirdLife South Africa. In 1975 Rohwer proposed that variable plumage traits of wintering flocking birds evolved to signal individual dominance status. Evidence from more than 50 papers on the so-called status signaling hypothes...

Experimental confirmation that avian plumage traits function as multiple status signals in winter contests

Personality Traits and Multiple Intelligences as Predictors of Reading Proficiency among Iranian EFL learners

The present study investigated the relationship between personality traits and multiple intelligences, and learners’ reading proficiency. To this end, 384 graduate EFL students participated in the present study. Two questionnaires, namely the NEO personality inventory-revised, and McKenzie’s (1999) MI inventory as well as a sample TOFEL reading comprehension test were used to collect the data. ...

Multiple intelligences: Can they be measured?

This paper is about issues relating to the assessment of multiple intelligences. The first section introduces the authors’ work on building measures of multiple intelligences and moral sensitivities. It also provides a conceptual definition of multiple intelligences based on Multiple Intelligences theory by Howard Gardner (1983). The second section discusses the context specificity of intellige...

Interspecific variation in plumage colour among birds: species recognition or light environment?

The traditional explanation for interspecific plumage colour variation in birds is that colour differences between species are adaptations to minimize the risk of hybridization. Under this explanation, colour differences between closely related species of birds represent reproductive character displacement. An alternative explanation is that interspecific variation in plumage colour is an adapt...
