Genetic Variability of Ceraeochrysa cincta, Ceraeochrysa claveri, and Ceraeochrysa cubana (Neuroptera: Chrysopidae) Populations in Agroecosystems of Southeast Brazil
(Environmental Entomology, 2020) [Artigo]The species of the genus Ceraeochrysa, known as green lacewings or trash-carriers, are widely distributed along the Americas and its islands. In Brazil, 28 species are found, including Ceraeochrysa cincta (Schneider), ... -
Exogenous silicon and salicylic acid applications improve tolerance to boron toxicity in field pea cultivars by intensifying antioxidant defence systems
(Ecotoxicology and Environmental Safety, 2020) [Artigo]Field peas (Pisum sativum L.) are widely cultivated throughout the world as a cool season grain and forage crop. Boron (B) toxicity is caused by high B concentration in the soil or irrigation water, and is particularly ... -
Growth, morphological, metabolic and photosynthetic responses of clones of eucalyptus to glyphosate
(Forest Ecology and Management, 2020) [Artigo]We hypothesized that eucalyptus has clone-dependent responses to glyphosate, and such differential responses might be associated with morphological, metabolic and/or photosynthetic changes. Experiments were carried out ... -
Response of Corn Seedlings (Zea mays L.) to Different Concentrations of Nitrogen in Absence and Presence of Silicon
(Silicon, 2020) [Artigo]Corn plants are highly demanding of nitrogen and the application of silicon has been studied because it minimizes stress from different natures, and for the better utilization of some nutrients by the plants. Thus, the ... -
Silicon toxicity induced by different concentrations and sources added to in vitro culture of epiphytic orchids
(Scientia Horticulturae, 2020) [Artigo]Silicon has been added to the in vitro culture medium of orchids as a beneficial element that can successfully improve tissue culture. However, although supplemental Si may induce toxicity to the orchid culture depending ... -
Silicon in Pre-sprouted Sugarcane Seedlings Mitigates the Effects of Water Deficit After Transplanting
(Journal of Soil Science and Plant Nutrition, 2020) [Artigo]This study is aimed at assessing whether silicon (Si) can mitigate the effects caused by water stress in pre-sprouted seedlings (PSS) in sugarcane after their transplanting in the soil and what is the best form in the ... -
Fungicide spray coverage and deposition in soybean asian rust management
(Bioscience Journal, 2019) [Artigo]At maximum vegetative growth, sprays with fungicide to control Asian rust (Phakopsora pachyrhizi Sydow and P. Sydow) should reach high canopy penetration and plant coverage. Therefore, the central objective of this study ... -
Additions to the knowledge of the pollen morphology of some Fabaceae from Cerrado forest patches of Brazil
(Palynology, 2020) [Artigo]This study presents the pollen morphology of 11 Brazilian native species and one variety of Caesalpinioideae and Detarioideae (Fabaceae) from forest patches of São Paulo, Brazil. The aim of this research is to expand the ... -
Silicon application induces changes C:N:P stoichiometry and enhances stoichiometric homeostasis of sorghum and sunflower plants under salt stress
(Saudi Journal of Biological Sciences, 2020) [Artigo]Beneficial effects of silicon (Si) on growth have been observed in some plant species, reportedly due to stoichiometric changes of C, N, and P. However, little is known about the effects on the stoichiometric relationships ... -
Size at onset of sexual maturity in macrobrachium amazonicum (Heller, 1862) phenotypes: An integrative approach
(Anais da Academia Brasileira de Ciencias, 2020) [Artigo]The size at the onset of sexual maturity (SOM) was determined in four hololimnetic populations of Macrobrachium amazonicum using morphometric, physiological and functional criteria. Male prawns from two populations analyzed ... -
Phenological diversity of maprounea guianensis (euphorbiaceae) in humid and dry neotropical forests
(Australian Journal of Botany, 2020) [Artigo]Phenological diversity, seasonality and leaf longevity may affect leaf habits, reflecting plant responses to environmental conditions. Maprounea guianensis Aubl. is a widespread species in Brazil that is associated with ... -
Pollen morphology of Rubiaceae from Cerrado forest fragments: Pollen unit, polarity and diversity of the types of apertures
(Review of Palaeobotany and Palynology, 2020) [Artigo]The pollen morphology of 23 Brazilian native species of Rubiaceae Juss. from forest fragments of a Cerrado area was analyzed using light microscopy (LM) and scanning electron microscopy (SEM), in the search for new characters ... -
Aluminum-induced stomatal closure is related to low root hydraulic conductance and high ABA accumulation
(Environmental and Experimental Botany, 2020) [Artigo]Many studies ask how aluminum (Al) reduces the root growth, but as Al is mostly retained in the root system, physiological explanations for the also expected Al-induced decrease in stomatal conductance (gs) are unclear, ... -
The auxin-resistant dgt tomato mutant grows less than the wild type but is less sensitive to ammonium toxicity and nitrogen deficiency
(Journal of Plant Physiology, 2020) [Artigo]The low-auxin-sensitivity tomato mutant, dgt, despite displaying reduced plant growth, has been linked to greater resistance to N deficiency. This led us to test the role of auxin resistance of dgt in NH4+ toxicity and N ... -
Flammability thresholds or flammability gradients? Determinants of fire across savanna–forest transitions
(New Phytologist, 2020) [Artigo]Vegetation–fire feedbacks are important for determining the distribution of forest and savanna. To understand how vegetation structure controls these feedbacks, we quantified flammability across gradients of tree density ... -
Space use by giant anteaters (Myrmecophaga tridactyla) in a protected area within human-modified landscape
(Ecology and Evolution, 2020) [Artigo]Spatial ecology data are essential for conservation purposes, especially when extinction risk is influenced by anthropogenic actions. Space use can reveal how individuals use the habitat, how they organize in space, and ... -
Ovarian development in swimming crabs: Comparative histochemistry and ultrastructure of Callinectes ornatus and Arenaeus cribrarius (Brachyura, Portunidae)
(Tissue and Cell, 2020) [Artigo]The ovarian development of Callinectes ornatus and Arenaeus cribrarius was described using histochemistry and ultrastructure. Both species shows the same ovarian stages, which are the juvenile (JUV), adult rudimentary ... -
