Crescimento do pinhão-manso sob irrigação com água salina e adubação orgânica em condições de campo

The castor oil plant (Jatropha curcas L.) is a oil producer actually considered as a probable alternative for biodiesel production. It was aimed with this research to evaluate the effects of the application of different levels of replacement of the evapotranspiration, through the irrigation with saline water, and of the organic and mineral manuring in the growth of the castor oil plant under field conditions. The experiment was developed at the farm Barra, in the municipal district of Santa Luzia, in the Paraíba semiarid. The used statistical design was in randomized blocks, in a scheme of splitplots, with four repetitions. Five levels of replacement of water (25; 50; 75; 100 and 125% of the reference evapotranspiration) and three manuring types (organic, mineral and natural fertility, that is, without manuring) were studied. It was verified that didn't happen significant effect of the irrigation water depths on the growth of the plants, except to the 150 days after the transplanting. The organic and mineral manurings promoted significant differences in the growth of the plants, in relation to the treatments without manuring; however, there were not statistical differences among the treatments with organic and mineral manuring. The smallest growth happened when the culture was submitted to the absence of the manuring.O pinhão-manso (Jatropha curcas L.) é uma planta produtora de óleo atualmente considerada com uma provável alternativa para produção de biodiesel. Objetivou-se com esta pesquisa avaliar os efeitos da aplicação de diferentes níveis de reposição da evapotranspiração, através da irrigação com água salina, e da adubação orgânica e mineral no crescimento do pinhão-manso sob condições de campo. O experimento foi desenvolvido na Fazenda Barra, no município de Santa Luzia, no semiárido paraibano. O delineamento estatístico utilizado foi em blocos casualizados, em um esquema de parcelas subdivididas, com quatro repetições. Foram estudados cinco níveis de reposição de água (25; 50; 75; 100 e 125% da evapotranspiração de referência) e três tipos de adubação (orgânica, mineral e fertilidade natural, isto é, sem adubação). Verificou-se que não ocorreu efeito significativo das lâminas de irrigação no crescimento das plantas, exceto aos 150 dias após o transplantio. As adubações orgânica e química promoveram diferenças significativas no crescimento das plantas, em relação aos tratamentos sem adubação; entretanto, não houve diferenças estatísticas entre os tratamentos com adubação química e orgânica. O menor crescimento ocorreu quando a cultura foi submetida à ausência da adubação

Adolpho Lutz and controversies over the transmission of leprosy by mosquitoes Adolpho Lutz e as controvérsias sobre a transmissão da lepra por mosquitos

During his years of study in Switzerland and Germany, Adolpho Lutz published his first articles on zoology, clinical practice, and therapeutics. In Limeira, São Paulo, he began studies on animal and human diseases caused by germs and parasites. In 1885-86, Lutz traveled to Hamburg to study the morphology of germs related to skin diseases, in conjunction with Paul Gerson Unna, one of Germany's foremost dermatologists. He proposed the inclusion of Hansen's and Koch's bacilli in a new genus. In 1889, Unna nominated his student as physician-in-chief of the Leper Settlement on Molokai Island, Hawaii. From then on, Lutz sustained the theory that the disease was transmitted by mosquitoes. He conducted research to prove this theory when he was head of the Instituto Bacteriológico de São Paulo (1893-1908) and, later, after he moved to the Instituto Oswaldo Cruz (1908-1940). Although this research was not successful, on commissions and at congresses in which he participated until his death in October 1940, he still held to his conviction that leprosy was transmitted by mosquitoes.<br>Quando estudava na Suíça e Alemanha, Adolpho Lutz publicou os primeiros trabalhos sobre zoologia, clínica e terapêutica.

Lutz passou a defender a transmissão da doença por mosquitos. Realizou pesquisas para provar esta teoria depois que assumiu a chefia do Instituto Bacteriológico de São Paulo (1893-1908) e, sobretudo, após a transferência para o Instituto Oswaldo Cruz (1908-1940). Apesar de não terem sido bem-sucedidas estas pesquisas, sustentou a transmissão da lepra por mosquitos nas comissões e congressos de que participou, até sua morte em outubro de 1940

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
