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

Morpho-agronomic trait comparisons among Tagetes patula L. cultivars

The objective of this work was to characterize Tagetes patula L. cultivars (Spry, Orange, Flame and Yellow) as to the following morpho-agronomic characteristics: plant height, number of stems and inflorescences / plant, stem and inflorescence diameters, flowering cycles and durations, fresh and dry matter weights of aerial parts (including stem, leaves and flowers) and roots The work has been carried out in a greenhouse at the Genetics Department, Campinas Agronomic Institute, Sao Paulo State, Brazil. A randomized complete blocks design was used with four replicates. The results revealed that the late flowering cycle cultivars revealed higher plants and thicker stems, bigger inflorescences, higher dry matter weights in aerial parts and roots and shorter blooming period durations. Early flowering cycle length cultivars presented higher number of inflorescences per stem and longer blooming period durations

Regeneração de plantas a partir de calos em gladíolo.

Para a proliferação in vitro de calos de gladíolo (Gladiolus x grandiflorus L.), utilizaram-se gemas como explantes adicionadas em meio MS com 0,5 mg/L de 6-benzilaminopurina (BAP) e 1,0 mg/L de ácido naftalenoacético (ANA). Para a regeneração dos calos, testaram-se as concentrações de BAP (0; 0,5; 1,0; 2,0 e 4,0 mg/L) em combinação com ANA (0; 0,1 e 1,0 mg/L), em todas as combinações possíveis formando um esquema fatorial 5 x 3. A regeneração dos calos formados foi melhor na concentração 0,1 mg/L de ANA e na ausência de BAP, produzindo, em média, 2,07 brotos com tamanho médio de 2,27 cm. O objetivo do trabalho foi encontrar uma concentração ideal de reguladores de crescimento para a regeneração de plantas a partir de calos de gladíolo

Germinação de sementes de sempre-vivas (Syngonanthus elegans e S. venustus).

A sempre-viva é uma espécie ornamental nativa, com ocorrência endêmica em algumas regiões brasileiras. Atualmente, encontra-se entre as principais espécies exportadas e seu consumo interno também é expressivo. Mas, apesar da sua importância comercial, poucas são as informações agronômicas sobre seu cultivo. Sabe-se que são propagadas por meio de sementes, preparadas pelos próprios produtores de flores. Assim, visando avaliar características das sementes, coletaram-se capítulos florais de Syngonanthus elegans e S. venustus ? cultivados na região de Diamantina (MG) ? dos quais se retiraram as sementes, que foram submetidas a testes de germinação, avaliando-se efeitos das temperaturas de 20, 25, 30 e 35 °C. Utilizaram-se quatro repetições com 50 sementes em cada caixa plástica tipo gerbox. As sementes das duas espécies tiveram maior percentagem e velocidade de germinação a 25 °C, mas não germinaram quando submetidas à temperatura de 35 °C. As sementes de Syngonanthus venustus também tiveram primeira contagem e IVG (Índice de velocidade de germinação) superiores às de Syngonanthus elegans

Weather Forecasting by Insects: Modified Sexual Behaviour in Response to Atmospheric Pressure Changes

<div><p>Prevailing abiotic conditions may positively or negatively impact insects at both the individual and population levels. For example while moderate rainfall and wind velocity may provide conditions that favour development, as well as movement within and between habitats, high winds and heavy rains can significantly decrease life expectancy. There is some evidence that insects adjust their behaviours associated with flight, mating and foraging in response to changes in barometric pressure. We studied changes in different mating behaviours of three taxonomically unrelated insects, the curcurbit beetle, <i>Diabrotica speciosa</i> (Coleoptera), the true armyworm moth, <i>Pseudaletia unipuncta</i> (Lepidoptera) and the potato aphid, <i>Macrosiphum euphorbiae</i> (Hemiptera), when subjected to natural or experimentally manipulated changes in atmospheric pressure. In response to decreasing barometric pressure, male beetles exhibited decreased locomotory activity in a Y-tube olfactometer with female pheromone extracts. However, when placed in close proximity to females, they exhibited reduced courtship sequences and the precopulatory period. Under the same situations, females of the true armyworm and the potato aphid exhibited significantly reduced calling behaviour. Neither the movement of male beetles nor the calling of armyworm females differed between stable and increasing atmospheric pressure conditions. However, in the case of the armyworm there was a significant decrease in the incidence of mating under rising atmospheric conditions, suggesting an effect on male behaviour. When atmospheric pressure rose, very few <i>M. euphorbiae</i> oviparae called. This was similar to the situation observed under decreasing conditions, and consequently very little mating was observed in this species except under stable conditions. All species exhibited behavioural modifications, but there were interspecific differences related to size-related flight ability and the diel periodicity of mating activity. We postulate that the observed behavioral modifications, especially under decreasing barometric pressure would reduce the probability of injury or death under adverse weather conditions.</p></div
