The purpose of this study was analyze the competencies of science teacher candidate after the bryological exploration. The intended competence of science teacher candidate was the ability to apply the concept and science ability to explore plant diversity that could be found around the environment.This field trip was conducted by exploring liverworts, hornworts, and mosses as well. This descriptive research was conducted during March until April 2017 at Universitas Negeri Surabaya (UNESA) and Sumber Brantas Arboretum in Malang, as the location of exploration. The subjects of this study were 76 candidate of teachers from science educations department, which is divided into three classes. The competences observed on this study were describing, identifying, collecting specimens, furthermore. The research instruments were observation sheets, product assessment sheets, and response questionnaire. The data were analyzed descriptive-quantitatively, in percentage and then categorized. The results of this study indicated that: the describing skill was categorized as ‘good’ identifying skill and collecting bryophytes was categorized as ‘very good’ and communicating skills was categorized ‘good’. In addition, the teacher candidates gave a very good response to field-trip-based learning. It can be concluded that the bryological exploration can develop the competences of science teacher candidates of Science Education Department of UNESA.

Historical review of bryological research in Fruška Gora Mt. (Serbia

Full Text Available Fruška Gora is a mountain located in the southern part of Pannonian plane and it is poorly bryologicaly investigated as well as most parts of Serbia. First data on bryophytes, for this region, were published in 1949 by Teodor Soška in his paper Pregled mahovina i lišajeva u okolini Beograda (Review of mosses and lichens in the vicinity of Belgrade. Soška listed 34 species of mosses and 8 liverworts species for this region. Later, in 1955, Zlatko Pavletić in his capital work Prodromus flore briofita Jugoslavije (Prodromus of Yugoslavian bryophyte flora, stated 26 moss species and 3 liverwort species, without indicating specific localities, but all of them were Soška’s original results. In 1966, the second botanist with original findings of bryophytes on Fruška Gora was Popović, who recorded 2 liverwort and 19 moss species, for this mountain, also without specific localities. By far, the most comprehensive data were given by Cvetić and Sabovljević in 2004. Their study A contribution to the bryophyte flora of Fruška Gora (Vojvodina, Serbia counted total number of 118 mosses and 14 liverworts, on 16 localities within National park Fruška Gora. The latest study on bryophytes of Fruška Gora was in 2013, and it is the first and so far, the last study of bryophyte assemblages on grasslands. Authors of this paper recorded 18 species of mosses from 29 releveé. Complete bryophyte flora of Fruška Gora is still unknown. Considering the fact that this is the region with high biodiversity, dense hydrological network and a rather complex geology, Fruška Gora certainly deserves further bryological researches.

REDOR NMR Reveals Multiple Conformers for a Protein Kinase C Ligand in a Membrane Environment

Full Text Available Bryostatin 1 (henceforth bryostatin is in clinical trials for the treatment of Alzheimer’s disease and for HIV/AIDS eradication. It is also a preclinical lead for cancer immunotherapy and other therapeutic indications. Yet nothing is known about the conformation of bryostatin bound to its protein kinase C (PKC target in a membrane microenvironment. As a result, efforts to design more efficacious, better tolerated, or more synthetically accessible ligands have been limited to structures that do not include PKC or membrane effects known to influence PKC–ligand binding. This problem extends more generally to many membrane-associated proteins in the human proteome. Here, we use rotational-echo double-resonance (REDOR solid-state NMR to determine the conformations of PKC modulators bound to the PKCδ-C1b domain in the presence of phospholipid vesicles. The conformationally limited PKC modulator phorbol diacetate (PDAc is used as an initial test substrate. While unanticipated partitioning of PDAc between an immobilized protein-bound state and a mobile state in the phospholipid assembly was observed, a single conformation in the bound state was identified. In striking contrast, a bryostatin analogue (bryolog was found to exist exclusively in a protein-bound state, but adopts a distribution of conformations as defined by three independent distance measurements. The detection of multiple PKCδ-C1b-bound bryolog conformers in a functionally relevant phospholipid complex reveals the inherent dynamic nature of cellular systems that is not captured with single-conformation static structures. These results indicate that binding, selectivity, and function of PKC modulators, as well as the design of new modulators, are best addressed using a dynamic multistate model, an analysis potentially applicable to other membrane-associated proteins.

Bryological surveys and collections were made in order to assess the natural colonization of mosses (and liverworts) on acid minesoils of a reclamation demonstration site located adjacent to Goose Lake Prairie State Park in northeastern Illinois. Four types of fine-textured mineral soils were recognized within the site; these were designated as abandoned (cultivated) field soil, oil minesoil (spoil), reclaimed minesoil 1972 to 1973, and reclaimed minesoil 1975 to 1976. The two reclaimed minesoils were distinguished by reclamation efforts begun in 1972 and 1975. Thirty moss taxa and one liverwort species were found on the site, and two additional moss species were found in areas adjacent to the site. Of the 33 bryophyte taxa recognized, 14 species of mosses were new reports for Grundy County. Comparative distribution patterns indicate that the major pioneer species of mosses on reclaimed minesoil were Barbula unguiculata, Ceratodon purpureus, Ditrichum pallidum, and Funaria hygrometrica. On the other hand, Bryum caespiticium and Weissia controversa were considered later seral species rather than primary invaders. Distribution patterns also indicate that mosses were generally unable to colonize unshaded bare reclaimed minesoil. However, moss colonization was successful in those areas where the harsh microhabitat conditions were ameliorated by vascular vegetation. Shoots of both living and dead higher plants most likely affect the proliferation of mosses by shading the soil surface, which results in increased moisture and decreased temperature at the soil surface in contrast to conditions of fully exposed soil.
