The Bryotrop project was planned in 1981 by several bryologists from Germany. Aim of this project was a comparative study of the bryoflora and -vegetation of rain forest areas in different parts of the tropics. In contrast to other bryological research in the tropics, this project should not be limited to pure floristic studies at various collecting sites but consist of interdisciplinary work of researchers from different fields together in a small region, an attempt which was not made before in bryology. For the field studies, the transect method was chosen. By this way a survey should be given of

Zingiberaceae is a family of monocotyledonous plants consisting of about 50 genera with a total of about 1600 known species of perennial herbs with tuberous rhizomes, distributed throughout tropical and sub-tropical forests. India has rich diversity of Zingiberaceae plants with nearly 200 of the world taxa occurring here. In Maharashtra 11 genera and around 40 species under this family are found in wild and cultivated state. Satpuda hills of Khandesh are lesser known for their wild Zingiberaceae members with only 5 species recorded in earlier floristic studies of the region. Present paper deals with the addition of Zingiber roseum to the flora of Jalgaon district and Khandesh region. The present record of Z. roseum is only the second record of this species from Maharashtra. The study provides a detailed taxonomic description, photographs and relevant information of above-mentioned plant species.

Conscious access to fear-relevant information is mediated by thresholdThe present report proposed a model of access consciousness to fear-relevant information according to which there is a threshold for emotional perception beyond that the subject makes hits with no false alarm. The model was examined by having the participants performed a confidence-ratings masking task with fearful faces. Measures of the thresholds for conscious access were taken by looking at the receiver operating characteristics (ROC) curves generated from a three-state low- and high-threshold (3-LHT) model by Krantz. Indeed, the analysis of the masking data revealed that the ROCs had threshold-like-nature (a two-limb shape) rather continuous (a curvilinear shape) challenging in this fashion the classical signal-detection view on perceptual processing. Moreover, the threshold ROC curve exhibited the specific y-intercepts relevant to conscious access performance. The study suggests that the threshold can be an intrinsic property of conscious access, mediating emotional contents between perceptual states and consciousness.

Amoebicidal Activity

Genetically uniform plant material, derived from Lychnis flos-cuculi propagated in vitro, was used for the isolation of 20-hydroxyecdysone and polypodine B and subjected to an evaluation of the antifungal and antiamoebic activity. The activity of 80% aqueous methanolic extracts, their fractions, and isolated ecdysteroids were studied against pathogenic Acanthamoeba castellani. Additionally, a Microtox® acute toxicity assay was performed. It was found that an 80% methanolic fraction of root extract exerts the most potent amoebicidal activity at IC50 of 0.06 mg/mL at the 3rd day of treatment. Both ecdysteroids show comparable activity at IC50 of 0.07 mg/mL. The acute toxicity of 80% fractions at similar concentrations is significantly higher than that of 40% fractions. Crude extracts exhibited moderate antifungal activity, with a minimum inhibitory concentration (MIC) within the range of 1.25–2.5 mg/mL. To the best of our knowledge, the present report is the first to show the biological activity of L. flos-cuculi in terms of the antifungal and antiamoebic activities and acute toxicity. It is also the first isolation of the main ecdysteroids from L. flos-cuculi micropropagated, ecdysteroid-rich plant material.

The aim of this research is to characterize wild annual sunflowers on the basis of achene micro-morphology. Plant material was grown up on an experimental field of the Institute of Field and Vegetable Crops in Novi Sad during 2015. Achene samples were hand-collected at the time of physiological maturity. Morphological measurements of achenes were performed using stereoscopic microscope Leica MZ16 with Leica DFC 320 Camera. The micro-morphological diversity of achenes was assessed using scanning electron microscopy (SEM). Obtained results indicated the presence of some quantitative and qualitative differences in achene characteristics among analyzed species, such as in their size, color, carpopodium and stylopodium shape, and distribution of trichomes on the achene surface. The carpopodium of examined species was asymmetrical at the maturity. Differences in the cuticle and wax ornamentation in different parts of the achenes, on the anticlinal walls of epidermal cells, were identified. The SEM analysis revealed the presence of non-glandular, multicellular bi-seriate trichomes (twin hairs) on the achene surface. This trichome type consisted of two elongated, parallel cells of different length. Considering the distribution of trichomes among the apical, median and basal regions of the fruit, most of the species demonstrated greater trichome density in the apical part.

The medieval British Isles were marked by a lively monastic presence throughout the entire period. Groups of monks, nuns, regular canons and canonesses, and friars established communities even in the furthermost reaches of the territory, and by doing so they came to play an important part in the life, culture, economy, and politics of the region. This paper will provide an overview of the arrival and spread of the different religious orders in England, Ireland, Wales, and Scotland, and by doing so, it will provide some comparative study of the different parts of the British Isles and examine how and when the spread and settlement of the various religious groups manifested itself across the islands, and what their impact was upon their localities and the society around them.
