FOLIAR SPRAYING OF DOSES OF BORIC ACID IN CORIANDER (Coriandrum sativum L.)

Coriander (Coriandrum sativum) is a species highly appreciated in Brazilian cuisine and of high nutritional importance due to the presence of vitamins, calcium, and iron. Leafy vegetables are considered nutritionally demanding as their cycles are relatively short and the lack of any essential element affects their growth, yield and quality. This study aimed to evaluate the response of coriander plants (Coriandrum sativum L.) to foliar spraying of boron doses. The experiment was carried out in a greenhouse at The State University of Goiás, Campus Ipameri, in Ipameri-GO. The experimental design was completely randomized, with five treatments and four replications. The treatments consisted of five boron doses applied by foliar spray (0, 1.0, 1.5, 2.0 and 3.0 kg ha-1) using boric acid (17% of Boron) as the source. Fresh and dry matter of shoot and root and leaf boron contents were evaluated. Data were subjected to analysis of variance (F test) and the effect of boron doses were evaluated by regression analysis. The application of 3.0 kg ha-1 of boron increases the boron content of coriander plants, and the fresh and dry matter of roots and shoots was not significantly increased

O PAPEL DAS MATAS CILIARES NA CONSERVAÇÃO DO SOLO E ÁGUA

O presente trabalho teve por objetivo correlacionar aspectos florestais com a importância da presença de vegetação para contenção de erosão, manutenção dos recursos hídricos e na conservação e manejo de solo e água. Atualmente, diante a intensificação do quadro de degradação de extensas áreas é um dos grandes desafios para o manejo e a conservação de solo. O uso inadequado dos solos para práticas agrícolas acompanhadas de movimentação de terra e da impermeabilização do solo dão início aos processos erosivos e ao transporte de materiais orgânicos e inorgânicos. Nesse contexto, as matas ciliares destacam-se quanto a transferência de energia e nutrientes de um ecossistema a outro, atuação no restabelecimento das condições químicas e físicas do solo, pela influência da matéria orgânica reciclada, o que evidencia a elevação dos teores de matéria orgânica e a melhoria da qualidade física do solo. A execução de práticas inadequadas resulta na perda de produção, assoreamento e a contaminação dos corpos hídricos e o desmatamento para abertura de novas áreas de produção, causando perda da biodiversidade, porém, para evitar tais danos é necessário planejar as atividades de produção agropecuária de acordo com a aptidão agrícola das terras, manejando o solo de acordo com suas fragilidades e potencialidades. Contudo, torna-se necessário viabilizar planos de proteção, recuperação e restauração de tais áreas, além de promover o uso racional das florestas, de forma a garantir a conservação da biodiversidade e a manutenção da qualidade de vida

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

INITIAL DEVELOPMENT OF GABIROBA (Campomanesia adamantium) ACCORDING TO FERTILIZATION WITH NITROGEN AND PHOSPHORUS

Campomanesia adamantium (Cambess.) Berg O. is a native of Savanna, popularly known as gabiroba, guavira, or gabiroba-do-campo, and has many uses, with its fruit being consumed fresh or processed. This study aimed to evaluate different doses of phosphorus and nitrogen in the initial development of gabiroba (Campomanesia adamantium) cultivated in pots. Five doses of phosphorus (0, 100, 200, 300, and 400kg ha-1 of P2O5) and three doses of nitrogen (0, 100, and 200 kg ha-1of N) were tested. The experimental design used was completely randomized in a 5x3 factorial scheme with six replications. The evaluations were carried out 120 days after plant emergence, and the variables analyzed were stem diameter, plant height, and number of leaves. Data were subjected to analysis of variance and F-test. The means were compared by the Tukey test at p<0.05. Regression analyzes were adjusted for phosphorus doses. The gabiroba responds significantly to the addition of phosphorus, with the dose of 400 kg ha-1 of P2O5 providing the highest height and the dose of 300 kg ha-1 of P2O5 providing the greatest stem diameter and the number of leaves. Up to 120 days old, gabiroba seedlings do not respond significantly to nitrogen fertilization
