A movimentação tópica numa visão pragmático discursiva

This paper retakes previous works on the topic and its development (Aquino, 1991; Fávero, 1993), the relevance of questions and answers in the discursive organization (Fávero, Andrade and Aquino, 1996; Fávero and Andrade, 1998; Fávero and Aquino, 1998, Fávero, 2001), in corpus constituted by spontaneous conversations, materials of project NURC, and printed or TV interviews. The objective is to examine the textual-interactive organization starting from three fundamental points: the discursive topic and its organization in the dialogical pair P-R, the topical movement in specific questions and the use of the digression as discursive strategy in the topical movement

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016
