Abstract Recent advances in molecular phylogenetics and a series of important palaeobotanical discoveries have revolutionized our understanding angiosperm diversification. Yet, the origin early evolution their most characteristic feature, flower, remains poorly understood. In particular, structure ancestral flower all living angiosperms is still uncertain. Here we report model-based reconstructions for flowers at deepest nodes phylogeny angiosperms, using largest data set floral traits ever...
The stable carbon isotope composition of plant tissues, commonly expressed as δ13C, holds a wealth information about photosynthetic pathway, water relations and stress physiology. Crassulacean acid metabolism (CAM) is derived form photosynthesis that allows plants to fix at higher water-use efficiency compared the ancestral C3 photosynthesis. While central carbon-fixing enzyme plants, Rubisco, strongly discriminates against heavy 13C isotope, CAM characterized by dual use Rubisco much less...
Caryophyllales are highly diverse in the structure of perianth and androecium show a mode floral development unique eudicots, reflecting continuous interplay gynoecium their influence on position, number, identity androecial whorls. The five species from four genera paraphyletic Molluginaceae (Limeum, Hypertelis, Glinus, Corbichonia), representing three distinct evolutionary lineages, was investigated to interpret evolution across Caryophyllales. •Floral buds were dissected, critical-point...
Omega-3 fish oil supplements are widely consumed as source of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, presenting beneficial effects on human health.This study aimed to evaluate fifteen brands omega-3 available in Brazilian market order estimate the reality regarding those supplements.Twelve fatty acids were quantified by gas chromatography with a flame ionization detector (GC-FID), lipid profile obtained via mass spectrometry fingerprinting using direct electrospray (ESI-MS)...
We report experimental interspecific hybridization between Anastrepha fraterculus (Wiedemann), A. sororcula Zucchi, and obliqua (Macquart), widespread highly destructive crop pests in the Neotropical region. Prezygotic reproductive isolating mechanisms (such as different mating times male calling songs) seem to be easily disrupted no-choice crossing conditions, hybrid flies can obtained both directions most crosses. Crosses females males yield adult offspring of females. or only females,...
The tambaqui (Colossoma macropomum) is a native fish species that farmed most frequently and in the largest quantities throughout Brazil. high production of this from farms has contributed to occurrence emerging parasites, which may compromise health productivity. In batch 2500 fry acquired for experimental farming procedures Brazil, mortality rate 80% was observed, with swimming erratically gasping air at water surface. From among specimens were still alive, 60 individuals selected random....
Fire is a facilitating factor in the naturalisation of Eucalyptus globulus countries where it has been introduced. In this study, we investigate effect heat on dehiscence and germination free encapsulated seeds. Twelve combinations temperature (80, 150, 200°C) heating exposure time (30, 60, 120, 300 s) were used corresponding index (H) was computed. Dehiscence registered daily basis germinability seeds verified through tests. Results indicate that strongly dependent individual trees, but no...
The most species-rich and ecologically diverse plant radiation on the Canary Islands is Aeonium alliance (Crassulaceae). In island radiations like this, speciation can take place either within islands or following dispersal between islands. Aiming at quantifying intra- inter-island events in evolution of Aeonium, exploring their consequences, we hypothesized that (1) intra-island diversification resulted stronger ecological divergence sister lineages, (2) taxa with a longer history...
Margins of water reservoirs associated with dams can have high‐frequency tides, promoting soil erosion and nutrient leaching. We propose the use biocrusts for restoration ecological engineering purposes, due to their poikilohydric character, stabilize reservoir margins. promoted biocrust growth under controlled conditions, testing two types substrate: native sand organic substrate. After 2 months, grew on substrate covering almost all area, but not sand. This fast easy nature‐based solution...
Vegetable oils have properties that are beneficial to the human skin, and so, they being used increasingly as ingredients of many cosmetic preparations; however, targets adulteration.This study will evaluate authenticity Brazilian cosmetics based on vegetable (sesame, peanut, sunflower, almonds) determine composition fatty acids by gas chromatography with flame ionization detection (GC-FID) percentage in conjunction chemometric treatments (principal component analysis), lipid profiles using...
Abstract This paper is a discussion and elaboration of by Prenner & al. (2010), entitled “Floral formulae updated for routine inclusion in formal taxonomic descriptions”. The aim the was to promote use floral botany reach consensus among botanists best practice. An important purpose induce users observe describe flowers accurately. It proposed that additional information on anther, ovule, style stigma should be included. Also, only visible organs included formula theoretical speculations...
Acerola is a tropical fruit with large industrial and commercial appeal due to its organoleptic qualities bioactive compound-rich nature. Thus, as compounds (BC) stability of great interest in the food industry, assessment preserving techniques prolong shelf life has become imperative. Hence, purpose this study was evaluate how storage affects BC conservation microencapsulated lyophilized acerola pulps over 180 days. For matter, antioxidant tests, physical-chemical analyzes, vitamin C...
In several flowering plants, pollen is not delivered directly from the anthers to pollinators but transferred and presented by another floral structure, a phenomenon known as secondary presentation (2PP). The new pollen-presenting that is, presenter, usually style, other organs may also be involved in this within-flower transfer. This transfer happens during late bud development when already released thus associated with extreme protandry. evolutionary significance of 2PP reflected its...
This study describes aspects of the infection caused by myxosporean genus Henneguya, which forms cysts in bony portion gill filaments Hypophthalmusmarginatus. Specimens this catfish were acquired dead from artisanal fishermen near town Cametá, state Pará, northern Brazil, between July 2011 and May 2012. They transported refrigerated containers to Carlos Azevedo Research Laboratory at Federal Rural University Amazonia, Belém, where analyses performed. After confirmation parasitism observation...
The developed method (DM) allows to perform experiments in shorter time with reduced amount of sample and reagent for fatty acids (FA) determination fermented milk samples.Design Expert software was employed discover the greatest sonication (7 20 min) concentration alkaline acidic reactions (0.70 1.5 mol L -1 ).Validation procedures were applied yogurt samples diverse fat content, ranging from 1.22 2.83%, being agreement acceptable values.Besides, intraday relative standard deviation (RSD)...
Adaptive radiation is a significant driver of biodiversity. Primarily studied in animal systems, mechanisms that trigger adaptive radiations remain poorly understood plants. A frequently claimed indicator plants growth form diversity when tied to the occupation different habitats. However, it remains obscure whether morphological adaptations manifest as per se or its constituent traits. We use classic Aeonium from Canary Islands ask adaptation across climatic space structured by evolution....
Due to the amount of pigments, sugars and fibers found in fruits, fatty acid quantification process leads errors, such as its underestimation matrix.Therefore, proposed method allows performing experiments shorter time with reduced sample reagent.Design Expert software was used find validated for alkaline acidic reactions, which were six eight minutes, respectively, both concentration 0.5 mol L -1 .The validation made avocado pulp different fruits application method, as: apple, mango,...
Sugarcane (Saccharum officinarum L.) ensilage presents serious limitations due to the conversion of soluble carbohydrates into ethanol, thus, it is necessary use additives that reduce losses DM during process. The aim this study was evaluate effect increasing levels detoxified castor-bean (Ricinus communis meal (DCBM) on nutritive value, fermentation pattern, stability and sugarcane silages. Twenty mini-silos with five different concentrations DCBM (0, 50, 100, 150 200 g kg-1 fresh matter)...
