Herbivore handling of a plant's trichome: Nymphalidae and Passiflora lobata Killip Hutch. Despite evidence that herbivores are negatively affected by trichomes there also reports of insect counter-adaptations that circumvent the plant's defense.
This paper reports on a study that investigated the likely mechanisms employed by larvae of the nymphalid butterfly, Heliconius charithonia L. Evidence were gathered using data from direct observations of larval movement and behavior, faeces analysis, scanning electron microscopy of plant surface and experimental analysis of larval movement on plants with and without trichomes manually removed. The latter involved a comparison with a non specialist congener, Heliconius pachinus Salvin.
Observations showed that H. Moreover, wandering larvae lay silk mats on the trichomes and remove their tips by biting. In fact, trichome tips were found in the faeces. Experimental removal of trichomes aided in the movement of the non specialist but had no noticeable effect on the specialist larvae.
These results support the suggestion that trichomes are capable of deterring a non specialist herbivore H. The precise mechanisms that allow the success of H. Future studies should ascertain whether larval integument provides physical resistance to trichomes. We have developed reproducible micropropagation, callus culture, phytochemical, and antioxidant analysis protocols for the wild passion fruit species P.
Genotype and explant origin-linked differences are visible amongst the Passiflora species concerning callus production, total phenolics, and antioxidant activity. The protocols developed for screening phytochemicals and antioxidants in P. The high level of phenolic compounds seems to account for the antioxidant activity of methanolic extracts of P. The methanolic extracts of callus derived from P.
The optimized micropropagation and callus culture protocols have great potential to use cell culture techniques for further vegetative propagation, in vitro germplasm conservation, and secondary metabolite production using biotic and abiotic elicitors.
Antiprotozoal activity of Neurolaena lobata. Extracts, fractions and sesquiterpene lactones from Neurolaena lobata L. Asteraceaea traditional medicinal plant from Guatemala, were tested in vitro against Leishmania spp. The ethanol extract inhibited the parasite growth of L. The pure germacranolides 1 and a mixture of 2 and 3, isolated from the ethonal extract, were highly active against L. Cyanohydrin glycosides of Passiflora. These alpha-hydroxyamides, presumably formed during processing of the plant material, behave as cyanogenic compounds when treated with commercial Helix pomatia crude enzyme preparation.
Thus, the enzyme preparation appears to contain an amide dehydratase, which converts alpha The leaves

Due to their high morphological plasticity and complex evolutionary history, the species boundaries of many reef-building corals are poorly understood. The skeletal structures of corals have traditionally been used for species identification, but these structures can be highly variable, and currently we lack knowledge regarding the extent of morphological variation within species.
Porites species are notorious for their taxonomic difficulties, both morphologically and genetically, and currently there are several unresolved species complexes in the Pacific. Despite its ubiquitous presence and broad use in coral research, Porites lobata belongs to one such unresolved species complex.
To understand the degree of intraspecific variation in skeletal morphology, corallites from the Hawaiian P. A subset of samples from two genetically differentiated populations from contrasting high- and low-stress environments in Maunalua Bay, Hawaii, were then quantitatively analyzed using multivariate morphometrics. Our observations revealed high intraspecific variation in corallite morphology, as well as significant morphological differences between the two populations of P.
Additionally, significant correlation was found between the morphological and genetic distances calculated from approximately 18, loci generated from restriction site-associated DNA sequencing. The unique morphological characters observed from the genetically differentiated population under environmental stress suggest that these characters may have adaptive values, but how such traits relate to fitness
Paribas barba azul reproduccion asexual how much plasticity they can exhibit remain to be determined by future studies.
Relatively simple morphometric analyses used in our study can be useful in clarifying the existing ambiguity in skeletal architecture, thus contributing to resolving species issues in corals.
