Para conocer el cruzamiento intraespecífico y su posible implicación en la domesticación del Cempoalxochitl (Tagetes erecta L.), se realizó manualmente autopolinización polinización cruzada intrapoblacional (PaP) T. cultivada pariente silvestre. La silvestre produjo poca semilla (17 %), mientras que cultivado fue mayor (74 %); con PaP, hubo alta producción de semillas ambas poblaciones (91 a 95...

Considering that habitat use by amphibians is related both with climate and environmental features, we tested the hypothesis that anuran assemblages found in different phytophysiognomies and in different seasons vary in structure. Additionally, we searched for species which can be indicators of habitat and seasons. The study was conducted in the Pampa biome, southern Brazil. Sampling was done t...

Background: Several plant species belonging to the Asteraceae family are widely used as sources of traditional medicines. The current study was aimed at providing a systematic review ethnomedicinal, phytochemical and pharmacological properties medicines in Zimbabwe. Methods: Information related systematically collected using relevant keywords from online databases such BioMed Central, Web Scien...

Pseudis minuta is abundant in a variety of aquatic environments of the Pampa domain. Therefore, it can be considered a good model for testing hypotheses on environmental heterogeneity and the influence of climate on the activity of anurans. In this study, we examined the spatial distribution pattern of P. minuta in terms of microhabitats and the influence of abiotic factors on seasonal fluctuat...

Costus spicatus (Jacq.) Sw. and Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae) are economically important plants due to their pharmacological and medicinal properties and ornamental value. These plants are natives from the Brazilian Atlantic Rainforest and are fed upon by Agaraea minuta Schaus, 1892 (Lepidoptera: Arctiidae). This study describes the damage done by A. minuta on C. spic...
