A library of 600 taxonomically diverse Panamanian plant extracts was screened for fungicidal, insecticidal, and herbicidal activities. A total of 19 active extracts were submitted to HPLC-based activity profiling, and extracts of Bocconia frutescens, Miconia affinis, Myrcia splendens, Combretum aff. laxum, and Erythroxylum macrophyllum were selected for the isolation of compounds. Chelerythrine...

Ixodes affinis, which is similar morphologically to Ixodes scapularis, is widely distributed in North Carolina. Collections have documented this species in 32 of 41 coastal plain counties, but no piedmont or mountain counties. This coastal plain distribution is similar to its distribution in Georgia and South Carolina, where it is considered an enzootic vector of Borrelia burgdorferi sensu stri...

The research is based on the unique collections of tropical and subtropical plants MBG. Phytosanitary monitoring was carried out in laboratory «Tropical Subtropical plants»: Orangery, glass greenhouse Korean greenhouse. As a result phytosanitary complex MBG, next pests were identified: Trialeyrodes vaporariorum Westw.; Pseudococcus affinis Mask.; Diaspis boisduvalii Sign.; Tetranychus urticae L...

The Alpheidae-possibly the most diverse family of recent decapod crustaceans-offers attractive opportunities to study the evolution of many intriguing phenomena, including key morphological innovations like spectacular snapping claws, highly specialized body forms, facultative and obligate symbioses with many animal groups, and sophisticated behaviors like eusociality. However, studies of these...

Variation in nuclear DNA content within some eukaryotic species is well documented, but causes and consequences of such variation remain unclear. Here we report genome size of an estuarine and salt-marsh calanoid copepod, Eurytemora affinis, which has recently invaded inland freshwater habitats independently and repeatedly in North America, Europe, and Asia. Adults and embryos of E. affinis fro...
