Collecting and evaluation of germplasm of spiked pepper from Brazilian Amazon

Piper aduncum L. é uma planta que ocorre na Amazônia Brasileira com elevado teor de óleo essencial e que apresenta propriedades biológicas utilizáveis na agricultura e saúde humana. Com o objetivo de avaliar germoplasma visando ao melhoramento genético e cultivo econômico, realizaram-se coletas (inflorescências, estacas, folhas e ramos finos) em dez municípios da Amazônia Brasileira (Manaus, Marabá, Goianésia, Moju, Belém, Santa Izabel, Americano, Bonito, Santarém Novo e Aveiro). Tomaram-se dados do ambiente, populações e de doze caracteres morfoagronômicos (número de folhas por ramo, comprimento da folha, largura da folha, circunferência do ramo mais velho, altura da planta, número de ramos ortotrópicos, número de ramos plagiotrópicos, comprimento do entrenó, número de espigas por ramo, rendimento de óleo, teor e produção de dilapiol). As inflorescências e estacas foram identificadas e encaminhadas para a UFRA em Belém-PA e, as folhas e ramos finos, para o Museu Paraense Emílio Goeldi-MPEG, para extração do óleo essencial (hidrodestilação). Utilizaram-se estimadores de média, desvio padrão, coeficiente de variação e amplitude total para estudo da variabilidade fenotípica. As matrizes prevalenceram em ambientes antropizados, solos argilosos, condições de drenagem variáveis, terrenos planos e clima Ami, como também predominaram populações definíveis pela agregação dos indivíduos, em terra alta e a pleno sol, serrapilheira, tamanho das populações e presença de plântulas no chão muito variáveis. Os caracteres de maior variabilidade foram número de ramos ortotrópicos, número de espigas por ramo, circunferência do ramo mais velho (morfológicos), teor e produção de dilapiol (agronômicos). Concluiu-se que a espécie apresenta adaptação a diferentes ambientes com relação à vegetação, solo, clima, relevo e drenagem, facilitando o cultivo e domesticação. Há variabilidade morfoagronômica favorecendo a seleção e fitomelhoramento.

Diastolic blood pressure associated with accumulated work time among drivers and collectors

The relationship between diastolic blood pressure and the variables total cumulative working time and age was examined by regression analysis. The study was carried out among 839 bus drivers and conductors, users of an occupational health center in Campinas, S. Paulo State, Brazil. The main results were a positive association between diastolic blood pressure and cumulative working time, as well as an interaction between this variable and the bus worker's age.

A simple and effective air shotgun for collecting small birds and other vertebrates at close range

Scientific collections are important sources of material for many areas of ornithological research. Although firearms (particularly shotguns) have been the standard for avian scientific collecting for more than 100 years, their use is restricted in many areas of the world. We describe a cheap, relatively silent, and effective air shotgun for collecting birds weighing up to 50 g at distances up to 4 m. This air shotgun is capable of shooting birdshot, uses hollow metal rivets connected to plastic straws as shot shells, and represents a simple adaptation of any 0.177 or 0.22 cal single-shot, break-barrel air rifle with at least 25 joules of muzzle energy. This air shotgun will be especially useful for focused sampling of birds (and other small vertebrates) in situations where firearm use or transport is restricted.

A Forgotten Original or an Original Copy? On MS. Douce 387 in the Bodleian Library: Collecting Early Modern Festival Books

Focusing on one manuscript, today in the Bodleian Library, Oxford, this chapter deals with the question how early modern objects became collectable items. The manuscript is categorized as MS. Douce 387 and its name indicates that it came from the collection of Francis Douce (1757–1834), who was keeper of manuscripts in the British Museum from 1799 until 1811. MS. Douce 387 is described in the catalogue of the Douce’ian collection as the “presentation copy with coloured designs by Marten de Vos and others” of the 1595 printed festival book Descriptio publicae gratulationis … in adventu … Ernesti archiducis Austriae. This festival book, printed in Antwerp’s Plantin-Moretus press, was commissioned by the magistrate of the city of Antwerp to commemorate the Joyous Entry of Archduke Ernest of Austria from June 1594; that an “archducal copy” bound in red velvet was commissioned as well and was owned by the Archduke is know as well. However, first research showed that Oxford copy cannot be this “archducal copy” or Marten de Vos’s artist’s copy even though it is the only know version with a handwritten text and hand-drawn illustrations. It rather should be examined as something totally different altogether. The main question remains why someone then commissioned a hand made version of this festival book, something unknown for other books of this genre? Why would someone between 1600 and 1800 sit down and copy texts and prints from a collectable book? Why was there such an on-going interest in early modern festival books? Could this manuscript be the only later made copy of the “archducal volume” or is it rather a forgery made for the European collectors’ market?
