Croton bacupariensis, an endemic species from the coastal plain of State Rio Grande do Sul, southern Brazil, is described and illustrated. The new shares morphological features with gnaphalii, but differs mainly by habit, indumentum leaves morphology pistillate flowers. In addition; C. gnaphalii occurs all over Pampa’s grasslands Argentina, Uruguay Sul.
The objective of this work was to evaluate the genetic variability for synthesis bioactive compounds and minerals in pumpkin (Cucurbita moschata) landraces. Total phenolic compounds, carotenoids, antioxidant activity were evaluated 10 accessions Cucurbita moschata landraces from Genebank Embrapa Temperate Agriculture (Pelotas - RS, Brazil). Twenty plants each accession cultivated field during spring/summer 2013/2014. After harvesting mature fruits, seeds discarded opposite longitudinal...
Loopers such as Chrysodeixis includens (Walker), Rachiplusia nu (Guenée), and Trichoplusia ni (Hübner) are important defoliators in soybean, sunflower, crucifer crops, respectively, countries of the Americas. The biotic potential these polyphagous species Plusiinae was comparatively examined considering crop rotation succession scenarios which crops cultivated during or after Brazilian winter. All developed reproduced on soybean (BRS 133 Embrapa) forage turnip (Cati AL 1000, Wolf Seeds do...
This study describes the life cycle of Agrotis malefida Guenée, 1852 (Noctuidae: Noctuinae) under laboratory conditions. The insects were reared in a controlled environment (25 ± 1ºC, 70 10% RH and 14 hours photo phase) observed daily. larvae fed Greene's artificial diet adults offered sucrose solution. viability duration immature stages assessed. experiment initiated with 2,410 eggs. Larvae isolated shortly after hatching. Longevity, pre-, post- oviposition, fecundity fertility 13 adult...
Climate change can be associated with variations in the frequency and intensity of extreme temperatures precipitation events on local regional scales. Along coastal areas, flooding increased occupation has seriously impacted products services generated by marine life, particular biotechnological potential that macroalgae hold. Therefore, this paper analyzes available information taxonomy, ecology physiology discusses impacts climate stress Brazilian macroalgae. Based data compiled from a...
Squash is a food that meets the requirements of healthy diet and highly appreciated by consumers for its mild flavour high nutritional value. In southern Brazil, many farmers grow several pumpkin landraces are widely used in food. The consumption fruits derivatives benefits human health due to bioactive compounds, minerals, antioxidants fruit pulp, making functional objective this study was characterize antioxidant activity, minerals pulp (Cucurbita maxima) from Brazil. Phenolic carotenoids,...
Caperonia (Acalyphoideae, Euphorbiaceae) is a monophyletic genus with 36 species naturally distributed in Latin America, Africa, and Madagascar. Its greatest diversity occurs South where 28 are found. herbs or subshrubs that occur exclusively open marshy environments. Here, we describe itapevae, new endangered known from single record Brazil, based on extensive morphological study phylogenetic data.
We report the first record of Euphorbia pedersenii (Euphorbiaceae) for Brazil, a rare species previously known from few localities in Argentina. The belongs to sect. Nummulariopsis and is characterized by its small habit with well-developed tuberous root system, usually linear leaves, trapezoidal cyathial glands, pubescent ovary fruit. In state Rio Grande do Sul it grows open grasslands Pampa region, phytogeographic domain severely impacted agriculture. provide an assessment conservation...
Resumo Um inventário de fanerógamas da planície costeira região centro-norte do Rio Grande Sul, Brasil é apresentado. Durante dois anos, todas as fitofisionomias dos municípios Cidreira, Balneário Pinhal e Palmares Sul foram amostradas. As espécies classificadas quanto ao ambiente ocorrência, hábito preferencial, naturalidade grau ameaça. Foram coletadas 383 92 famílias, sendo 365 (95%) nativas 18 (5%) exóticas. famílias maior riqueza Asteraceae (45), Poaceae (30), Cyperaceae (24) Fabaceae...
During a taxonomic revision of the genus Croton from Pampas grasslands, some necessary adjustments were identified and are here presented. The study was based on new collections, field work analyses protologues type specimens. We treat C. allemii as synonym triqueter, stenotrichus hilarii, we designate lectotype for stenotrichus. lombardianus is newly reported Brazil macrobothrys record Atlantic Moist Forest in state Rio Grande do Sul. Updated information geographic distributions these...
