PREMISE OF THE STUDY Senna spectabilis var. excelsa (Fabaceae) is a South and Central American tree of great ecological importance and one of the most common species in several sites of seasonally dry forests. Our goal was to develop microsatellite markers to assess the genetic diversity and structure of this species. METHODS AND RESULTS We designed and assessed 53 loci obtained from a micros...

[Carboxy-14C]-3-amino-5-hydroxybenzoic acid (AHBA) has been shown to be incorporated by Streptomyces spectabilis to the extent of greater than 0.1% (35: 1 dilution) in the ansamycin antibiotic streptovaricin C, the major component of the streptovaricin complex. When [carboxy-13C]AHBA was similarly administered, C-21 (quinone methide carbonyl at 188.3 ppm) of streptovaricin C was specifically la...

According to the crypsis hypothesis, the ability of female crab spiders to change body colour and match the colour of flowers has been selected because flower visitors are less likely to detect spiders that match the colour of the flowers used as hunting platform. However, recent findings suggest that spider crypsis plays a minor role in predator detection and some studies even showed that poll...

The Atlantic Forest with its exuberant vegetation of high level of biodiversity is classified as one hotspot of the world. Chemical composition of leaves from native trees and underlying soils was evaluated by INAA. The predominant species Euterpe edulis, Bathysa meridionalis, Hyeronima alchorneoides, Marlierea tomentosa, Gomidesia flagellaris, and Gomidesia spectabilis belonging to the diverse...

having special ecological condition, kish island has a restricted range of native species of ornamental plants. expansion of urban green space in this island is great of importance due to its outstanding touristy position in the south of iran. the purpose of this study was to investigate the growth and development of groundcover plants planted in four different regions of kish island and to rec...

Spittlebugs are among the main insect pests of forage grasses in Brazil. In February 2021, a spittlebug infestation was verified Xaraés palisadegrass (Brachiaria brizantha cv. Xaraés) municipality Senador Guiomard, Acre state, The specimens were captured with an entomological sweep net and identified as Notozulia entreriana (Berg) Mahanarva spectabilis (Distant) (Hemiptera: Cercopidae). is freq...
