Three new megastigmane glucopyranosides, komaroveside A [(3S,4R,5Z,7E)-3,4-dihydroxy-5,7-megastigmadien-9-one-3-O-β-D-glucopyranoside] (1), komaroveside B [(3S,4S,5S,6R,7E)-5,6-epoxy-3,4-dihydroxy-7-megastigmen-9-one-3-O-β-D-glucopyranoside] (2) and komaroveside C [(3S,4S,5S,6R,7E,9S)-5,6-epoxy-3,4,9-trihydroxy-7-megastigmen-3-O-β-D-glucopyranoside] (3) were isolated, together with eight known ...
We examined the vocal and non-vocal responses of male cricket frogs (Acris crepitans) to conspecific advertisement calls that had been attenuated or degraded by reducing the depth of amplitude modulation (AM). Both are characteristic of changes to the call as it is transmitted through natural habitats. As stimulus calls became more intense or less degraded, male cricket frogs gradually decrease...
1. The North Atlantic Oscillation (NAO) exerts considerable control on U.K. weather. This study investigates the impact of the NAO on butterfly abundance and phenology using 34 years of data from the U.K. Butterfly Monitoring Scheme (UKBMS).2. The study uses a multi-species indicator to show that the NAO does not affect overall U.K. butterfly population size. However, the abundance of bivoltine...
Abstract The aim of this research was to evaluate the survival and growth native tree saplings planted in a drained Mauritia flexuosa palm swamp (vereda) southeastern Brazil, identify suitable species for restoration projects these hygrophilous environments. Total sapling at one-year post-planting 48%. with highest were Croton urucurana, Cecropia pachystachya, Erythroxylum citrifolium, Hirtella...
A novel selenium- (Se-) hyperaccumulating plant, Cardamine hupingshanesis, accumulating Se as a form of SeCys2, was discovered in Enshi, Hubei, China, which could not be explained by present selenocysteine methyltransferase (SMT) theory. However, it is interesting to investigate if rhizosphere bacteria play some roles during SeCys2 accumulation. Here, one Se-tolerant rhizosphere strain, Microba...
Given that plants are sessile organisms, traits involved in adapting to local environments and/or in monitoring the surrounding environment, such as having photoreceptors, are significant targets of natural selection in plant evolution. To assess the intraspecific adaptive evolution of photoreceptors, we investigated sequence variations in four phytochrome genes (PHYA-C and PHYE) of Cardamine n...
A single specimen of the protasterid ophiuroid Protasterina flexuosa from the Kope Formation (Cincinnatian, Upper Or− dovician) of Kentucky exhibits three−dimensionally pyritized tube feet. This represents the first report of soft−tissue pres− ervation in an echinoderm from the type−Cincinnatian series. The tube feet are solid and lack all internal structure. They consist of aggregated masses o...
