The widely held assumption that any important scientific information would be available in English underlies the underuse of non-English-language science across disciplines. However, is expected to bring unique and valuable information, especially disciplines where evidence patchy, for emergent issues synthesising an urgent challenge. Yet such contribution communities application rarely quantified. Here, we show studies provide crucial informing global biodiversity conservation. By screening...

The palm swamps (i.e. Veredas) in the Cerrado, Brazilian Savanna, are priority areas for conservation. Veredas' hydrological characteristics fundamental maintenance of biodiversity and economic activities this region. However, despite importance, only a few studies have been carried out these areas, primarily surveys dragonflies (Insecta: Odonata). Here, we sampled twenty-five Cerrado We found 56 species Odonata, ten which were new records Mato Grosso do Sul State: Coenagrionidae (6),...
Abstract In general, environmental responses at level of populations or communities are preceded by alterations lower biological levels which can be efficiently detected the analysis biomarkers. We analyzed oxidative biomarkers TBARS and Catalase in Aegla singularis, a freshwater crustacean highly sensitive to changes. The objective was address if differences these related gender as well they influenced seasonal water physicochemical variables. results showed profile gender. female crabs...
Ilex paraguariensis is a native species to South America. Its economic importance in the use of its leaves and twigs processing product popularly known as "chimarrão". The aim this study was evaluate correlations between some physico-chemical process parameters oxidation I. oxidation. Maté with age 1.0, 6.5 12.0 months were subjected an for 3 h under different relative humidity conditions (80, 90 99%) at 26°C. extracts evaluated using experimental design techniques maximize total...
Purpose – The aim of this paper is to evaluate the effects ultraviolet (UV) light on color, secondary metabolites and sensory acceptance processed yerba-mate. Design/methodology/approach Samples were exposed UV for 72 hours. colorimetric coordinates (L*, a* b*) analyzed every 6 hours, while assessed at beginning end experiment. Methylxanthines phenolic compounds quantified by ultra performance liquid chromatography photodiode array detectors vegetable pigments UV/visible spectrophotometry....
In Brazil, yerba mate is consumed after processing; however, in Chile and Uruguay, the consumers prefer cured product, which acquires a yellow color. For that yerba-mate stored for period of six months to one year, increases cost final product overseas market. This study evaluated effect humidity temperature maturation chamber on time required get this characteristic. The changes color, pH, moisture water activity were during storage different conditions humidity. Yerba-mate subjected higher...
Climate change affects individual life-history characteristics and species interactions, including predator-prey interactions. While effects of warming on Aedes aegypti adults are well known, clarity the interactive climate (temperature CO2 concentration) predation risk larval stage remains unexplored. In this study, we performed a microcosm experiment simulating temperature changes in Manaus, Amazonas, Brazil, for year 2100. Simulated scenarios (SCCS) were accordance with Fourth Assessment...
Abstract Metals and agrochemicals are among the main aquatic contaminants, being able to trigger oxidative stress in exposed organisms. The objective of this work was evaluate correlation between level biomarkers Aegla crabs (Crustacea, Anomura) with (i) set metals present streams sediment (ii) land uses three hydrographic basins. study carried out (≤ 2nd order) basins southern Brazil (Basins Rio Suzana, Ligeirinho-Leãozinho Dourado). In these were quantified Cu, Cr, Cd, Fe, Mn Zn...
1. Avoiding freshwater insect extinctions requires studies assessing causal links between a human pressure and biodiversity measures (threats), the state of through time (status), solutions to manage species loss. However, an imbalance these different approaches on declines insects distribution countries may have implications for implementing conservation knowledge into practical actions. 2. Here, we evaluate country co‐authorship relationships quantitative bibliometric analysis identify...
Yerba-mate (Ilex paraguariensis St. Hil.) is a native species of South America, and its dried leaves are consumed mainly as beverage. Its phytochemical profile includes phenolic compounds consisting secondary metabolites with antioxidant activities. Current research optimizes conditions yerba-mate oxidation, evaluates the sensory acceptance assesses in vivo activity oxidized product. The variables incubation chamber humidity age were optimized within oxidative process by 22 factorial design....
Purpose – The purpose of this paper was to assess the changes in secondary metabolites and color during yerba-mate aging under controlled conditions. In Uruguay Paraguay, matured, which chlorophyll degradation occurs, is preferred. For matured product, stored for six months one year. Design/methodology/approach Processed submitted 35°C 80 per cent humidity 42 days a climatic chamber. Samples were collected every seven days, phenolic compounds/methylxanthines quantified by ultra-performance...
Understanding the genetic structure and diversity of plants is fundamental to their conservation permits sustainable use by local communities. The genus Maytenus (Celastraceae) composed possessing pharmacological antioxidant properties. However, economic properties species M. dasyclada, a typical Araucaria forests in Brazil Uruguay, have been little studied. In this work, natural populations dasyclada located unprotected preserved forest remnants were investigated using RAPD isozymes...
Glyoxylate cycle in fatty acid catabolism enhances net production of oxaloacetate, a substrate for gluconeogenesis, certain bacteria, invertebrates and oilseed the growth stage. A theoretical model was developed to calculate ATP amount produced each step catabolic pathway, taking into account acid’s hydrocarbon chain size. Results showed decrease energy efficiency glyoxylate when compared animal metabolism. Although provides evolutionary adaptations, it determines smaller per carbon atom acids.
Collema leptosporum was originally included in Collemataceae as part of the fasciculare group, an informal group that also C. fasciculare, papuanorum, and uviforme. However, molecular data from showed this species belongs to Arctomiaceae, all were relocated Arctomia, although no generated analyzed for leptosporum, papuanorum To investigate phylogenetic relationships currently Arctomia leptospora, we three DNA loci examined morphological anatomical features specimens collected near type...
