Effective mapping of large ignimbrites by using a GIS-based methodology; case of the Xáltipan ignimbrite from Los Humeros caldera, Mexico
Authors: Cavazos Álvarez Jaime Alberto , Carrasco-Núñez Gerardo
Published: November 2019

The Xáltipan ignimbrite (XI) records the largest single-eruption of the Trans-Mexican Volcanic Belt up to date (≥344 km3 uncompacted volume). As most large ignimbrites, the XI presents common challenges when mapping. These are abrupt welding variations, burial by younger units near other volcanic sources, and highly eroded deposits in active-water valleys. In this work, we deal with these issues by integrating classical cartographic techniques such as field measurements, geometric projections of energy lines and construction of geologic sections, with a GIS-based methodology that quantifies the eroded bulk. As a result, we obtained a map with the main XI features that is presented in an interactive format. Furthermore, we discuss the resources used for the map construction and how the results contributed to the interpretation of the eruptive history. These contributions include: 1) the energy lines point to a low-height pyroclastic density currents source, typical of caldera-forming, boiling-over eruptions; 2) the landscape of the XI, coupled with the geologic sections, indicate that in the proximal facies the ignimbrite filled a volcanic field, leaving a radially shaped distribution with a flat surface, while in the distal facies it channelized into a steep mountainous ground; and 3) the geologic sections in the valley areas, where the active rivers highly eroded the original XI deposits, revealed the preferential development of welded zones along channel centers.

The variables that affect colour in the digital textile printing process
Authors: Becky Gooby
Published: November 2019

The development of digital printing is a major change within the textile design process as a designer is no longer restricted to number of colours, repeat patterns, and may include photographic images and intricate detail. With digital print it is now possible to print anything between a metre, or hundreds of metres, at the click of a button.

However, there is a marked difference between screen-colour and print colour. A textiles designer using Computer Aided Design (CAD) to create a design will be required to experiment with a number of variables in order to feel more confident about the outcome when using digital fabric printing.
Izvještavanje o krizi i krizno komuniciranje Agrokora u 2017. godini putem internetskih platformi Večernji.hr i Agrokor.hr
Authors: Kanajet Karlo , Jakopović Hrvoje
Published: November 2019

Krizu organizacije označava situacija u kojoj se narušavaju redovite procedure funkcioniranja, a svaki izlazak iz uobičajenog toka djelovanja može dovesti i do pojačanog interesa medija. Kriza za neke organizacije zapravo počinje u onom trenutku kada je mediji proglase. Slučaj krize koncerna Agrokor u 2017. godini izazvao je veliku pozornost medija. Ovim se radom stoga proučavao slučaj kroz medijsko izvještavanje o Agrokoru na internetskom portalu Večernji.hr, u vrijeme kada se koncern suočavao s krizom izazvanom fi nancijskim problemima. Na taj su se način utvrdila obilježja i odrednice medijskog izvještavanja o Agrokoru i krizi na internetskom portalu Večernji.hr. S druge strane, analiza je obuhvatila službe-
na internetska priopćenja Agrokora na mrežnoj stranici Agrokor.hr kako bi se utvrdilo kako je koncern kroz službene online kanale odgovorio na krizu. Rezultati izvještavanja o slučaju Agrokor i njegovom kriznom komuniciranju daju uvid u obilježja medijskog izvještavanja u slučaju krize ovakvih razmjera i kriznom komuniciranju putem internetskih priopćenja. Istraživanje je pokazalo da se u medijskom portretiranju krize značajan naglasak stavlja na prvog čovjeka organizacije. Tako se na internetskom portalu Večernji.hr u promatranom razdoblju u gotovo svakoj drugoj objavi spominjao osnivač Agrokora Ivica Todorić. Također, više od trećine objava sadržavalo je brojke u kontekstu krize, poput visine duga koncerna. Što se tiče samog Agrokora, rezultati istraživanja pokazali su kako se organizacija u prvoj fazi suočavanja s krizom nije postavila aktivno. Službena internetska priopćenja na mrežnoj stranici Agrokor.hr, koja bi se ticala krize, izostala su, a poruke koje su putem portala Večernji.hr mogle doći do javnosti od strane koncerna sadržavale su elemente poricanja postojanja problema. Kako je kriza postajala sve složenija, Agrokor je bio prisiljen na promjenu komunikacije. Stoga se u drugoj fazi koristio konkretnim strateškim elementima kriznog komuniciranja kao što su sazivanje konferencije za medije, vidljivost prvog čovjeka organizacije, komunikacijska ujednačenost te preimenovanje.

Published: November 2019

The purpose of this paper is to determinate the influence of salinity on the
growth and development of pansies (Viola x wittrockiana Gams.). The
objective of the present study was to examine the cultivation area selection
and use of pansies related to the autumn and winter flowering aspects. A
total of 40 pansy seedlings were included in the study and allocated to four
groups of ten each. The experiment conducted four involved treatments:
control (K), treatment with 3g/l NaCl (T1), treatment with 5g/l NaCl (T2),
and treatment with 7 g/l NaCl (T3). Concentrated water was used for watering
the seedlings observed during growth. Over the course of the eight-week
experiment, the following quantitative and qualitative properties of the
pansy seedlings were measured: height, number of leaves, number of flowers,
diameter of flowers, length of leaves, width of leaves, as well as the
vitality and decorativeness of the pansy seedlings. The results obtained
show that pansies can tolerate increased amounts of salt (5 g/l and 7 g/l
NaCl) with adverse effects on the growth, development, vitality and
decorativeness of the plant.
Grassroots Adoption of Cloud-Based Storage Solutions
Authors: Raddatz Nirmalee I. , Stafford Thomas , Van Slyke Craig , Warkentin Merrill
Published: November 2019

The introduction of innovative technologies by employees into their workplace has been a long-standing practice. This informal introduction of technology within an organization without the organizational support or sanction is defined as “grassroots diffusion.” While a plethora of research studies have focused on factors contributing to individuals' technology adoption decisions, these studies have failed to understand the factors that contribute to technology adoption and continuance usage through the grassroots diffusion process. In understanding the factors that contribute to the grassroots diffusion process, we test a model by administering a survey to full- and part-time employees who use a cloud-based storage application for work-related tasks and who work for organizations that do not formally provide and require the use of the chosen application. The results suggest that source credibility, response cost, satisfaction, and perceived usefulness have significant influence on continuance usage intention of cloud-based applications adopted through the grassroots diffusion process.
Internal Motivators for the Protection of Organizational Data
Authors: Raddatz Nirmalee I. , Coyne Joshua G. , Trinkle Bradley S.
Published: November 2019

The purpose of this paper is to investigate the effect of internal motivators (psychological ownership, perceived control, and self-efficacy) on employees' intention to protect organizational data. The threat of cybersecurity breaches is increasing, as are the realization of cybersecurity breaches and the subsequent loss of data. While information security policies increase employees' intentions to protect organizational data, they do not guarantee employee compliance. Results indicate that self-efficacy is associated with perceived control, which, in turn, is associated with perceived psychological ownership of organizational data. Furthermore, self-efficacy and psychological ownership are both associated with an increase in intention to protect organizational data.

Published: November 2019

The clinical diagnosis of new-onset type 1 diabetes has, for many years, been considered relatively straightforward. Recently, however, there is increasing awareness that within this single clinical phenotype exists considerable heterogeneity: disease onset spans the complete age range; genetic susceptibility is complex; rates of progression differ markedly, as does insulin secretory capacity; and complication rates, glycemic control, and therapeutic intervention efficacy vary widely. Mechanistic and immunopathological studies typically show considerable patchiness across subjects, undermining conclusions regarding disease pathways. Without better understanding, type 1 diabetes heterogeneity represents a major barrier both to deciphering pathogenesis and to the translational effort of designing, conducting, and interpreting clinical trials of disease-modifying agents. This realization comes during a period of unprecedented change in clinical medicine, with increasing emphasis on greater individualization and precision. For complex disorders such as type 1 diabetes, the option of maintaining the “single disease” approach appears untenable, as does the notion of individualizing each single patient’s care, obliging us to conceptualize type 1 diabetes less in terms of phenotypes (observable characteristics) and more in terms of disease endotypes (underlying biological mechanisms). Here, we provide our view on an approach to dissect heterogeneity in type 1 diabetes. Using lessons from other diseases and the data gathered to date, we aim to delineate a roadmap through which the field can incorporate the endotype concept into laboratory and clinical practice. We predict that such an effort will accelerate the implementation of precision medicine and has the potential for impact on our approach to translational research, trial design, and clinical management.
Influence of Spectroscopic Techniques on the Estimation of the Degree of Conversion of Bulk-fill Composites
Authors: Bolaños-Carmona V , Benavides-Reyes C , González-López S , González-Rodríguez P , Álvarez-Lloret P
Published: November 2019

Objectives:

To compare the degree of conversion (DC) of different flowable and sculptable bulk-fill composites (BFC), at 0- and 4-mm depths from the surface, by Fourier transform infrared (FTIR), attenuated total reflection FTIR (ATR-FTIR), and FT-Raman spectroscopic techniques.

Methods and Materials:

Six BFC were investigated, including three sculptable composites (Admira Fusion [Voco], Aura Bulk Fill [SDI], and X-tra Fill [Voco]) and three flowable composites (Venus Bulk Fill [Heraeus], Filtek [3M], and X-tra Base [Voco]). Three molds of each composite were light cured as specified by the manufacturer. For each mold, slices corresponding to 0-mm (surface) and 4-mm depth were analyzed by spectroscopic techniques: ATR-FTIR, FTIR, and FT-Raman. The spectra of uncured composite material were used as an analytical control for background subtraction of the treated composite. The area and amplitude of the reference peaks (1607 and 1637 cm−1) were obtained to calculate the DC percentage at 0- and 4-mm depth. A Kruskal-Wallis nonparametric test was used for materials, and paired comparisons were made using Mann-Whitney nonparametric test. Wilcoxon's rank test was used for comparison between spectroscopic methods and between 0- and 4-mm depth in each composite. Significance was accepted at p<0.05.

Results:

FTIR showed significantly lower DC values, both in areas and amplitudes of the peaks, when compared with the results reported by different BFC. Differences between the surface and 4-mm depth were detected more precisely by FT-Raman. ATR-FTIR obtained DC values significantly higher than those obtained by FTIR.

Conclusions:

The vibrational spectroscopy method significantly influenced DC measurements of the flowable and sculptable BFC explored.
Efficacy of a Light-cured Tetracaine-based Anesthetic Gel for Rubber Dam Clamp Placement: A Triple-blind Randomized Clinical Trial
Authors: Wambier LM , Gonzaga CC , Chibinski ACR , Wambier DS , Farago PV , Loguercio AD , Reis A
Published: November 2019

Objectives:

To evaluate the efficacy of a new light-cured anesthetic gel for pain control in adults undergoing rubber dam isolation for the restorative treatment of noncarious cervical lesions (NCCLs).

Methods and Materials:

This study was a randomized, split-mouth, triple-blind, controlled trial. The sample comprised 50 adults with at least one pair of NCCLs located in the same arch but on opposite sides. Simple randomization defined the tooth to receive the light-cured tetracaine-based anesthetic gel or the placebo gel. After cotton roll isolation, the gels were applied in the gingival tissue around the tooth with the aid of the applicator tip of a syringe, left in place for 15 seconds, and light-cured for 15 seconds. Then, a #212 clamp was positioned on the tooth. If the patient reported pain, the clamp was removed, the patient filled out a pain intensity form (a 0-10 visual analog scale [VAS] and a 0-4 verbal rating scale [VRS]) and an injectable anesthetic was applied before rubber dam isolation for the restorative procedure. The absolute risk, intensity of pain, and need for rescue anesthesia were analyzed by the McNemar test and the Wilcoxon signed rank test (α=5%).

Results:

The odds ratio [OR] for pain (OR=3.5; 95% confidence interval [CI]=1.1 to 14.6; p=0.03) showed lower reports of pain for the light-cured anesthetic gel. One in five patients will benefit from placement of the light-cured anesthetic gel. On average, pain intensity was one VAS unit lower in those using the light-cured anesthetic gel than in those using the placebo gel. For the VRS, the pain intensity for the light-cured anesthetic gel was 0.4 units lower than the pain intensity for the placebo gel (95% CI=–0.9 to 0.07). The OR for rescue anesthesia was 2.5 (95% CI=0.7 to 10.9; p=0.18).

Conclusions:

The light-cured, tetracaine-based anesthetic gel reduced the absolute risk of pain by 20% in NCCLs.
How Do the Etching Mode and Thermomechanical Loading Influence the Marginal Integrity of Universal Adhesives?
Authors: Kaczor K , Krasowski M , Lipa S , Sokołowski J , Nowicka A
Published: November 2019

Objective:

This study evaluated the effect of etching mode and thermomechanical loading on universal adhesives.

Methods and Materials:

Two universal adhesives, Peak Universal and Adhese Universal, were used in two etching modes as the experimental groups: Peak Universal etch-and-rinse (PER), Peak Universal self-etch (PSE), Adhese Universal etch-and-rinse (AER), and Adhese Universal self-etch (ASE). Two adhesives considered gold standards were used as control groups: OptiBond FL (OER) was used as a control group for the etch-and-rinse (ER) mode, and Clearfil SE Bond (CSE) was used as a control group for the self-etch (SE) mode. Standardized class V cavities were created on the buccal and lingual surface in 30 extracted caries-free human third molars. Each adhesive and resin composite was applied according to the manufacturer's instructions. The specimens were subjected to thermomechanical loading (TML) immediately after the fillings were placed. Before and after TML, replicas and photographs of the fillings were performed and evaluated quantitatively and qualitatively. The Mann-Whitney U-test or Kruskal-Wallis test was used for quantitative analyses, and Fisher exact test was used for qualitative analysis.

Results:

Adhese Universal achieved a significantly higher percentage of continuous margin in the enamel than Peak Universal for the two types of etching both before and after TML (except for the SE group after TML). In dentin, the greatest percentage of continuous margin was achieved for Adhese Universal in the ER group (100%) before TML and for both universal adhesives in the SE groups (61%) after TML. For both etching modes and both time points, Adhese Universal had a greater percentage of continuous margin than Peak Universal for the whole margin. For the ER approach, significant differences were observed both before and after TML, and for the SE approach, significant differences were observed before TML. TML did not cause a significant decrease in the percentage of continuous margin in the enamel, but the results were the opposite in dentin. A qualitative assessment using World Dental Federation criteria did not show statistically significant differences between the groups.

Conclusions:

Scanning electron microscope assessment of marginal integrity showed that the evaluated factors such as etching mode and TML significantly influenced the marginal integrity of the universal adhesives. The replica method shows that laboratory and clinical assessment methods complement each other and give a broader view of marginal integrity.

REPRESENTASI SASTRA PERJALANAN DALAM KUMPULAN CERPEN SURAT DARI PRAHA DAN ANTOLOGI PUISI KEPADA KAMU YANG DITUNGGU SALJU KARYA YUSRI FAJAR
Authors: Shofi Imam
Published: November 2019

In recent years many books have been published containing travel stories, both trips made in Indonesia and abroad. Some are published in the form of short stories, memoirs, travel guide books, even poems or novels. This paper was raised as a form of positive response to the phenomenon. Short stories and letter poems from Praha and to you who awaited Yusri Fajar's snow work become one of the travel stories that tells about the author's journey. By using a changing perspective that is to analyze data and cases, the author uses the theory of travel writing concepts proposed by Carl Thompson in a book entitled Travel Writing (2011).
This research describes a person's journey contained in a collection of short stories and poetry anthologies entitled letters from Praha and to you who awaited the snow by Yusri Fajar. Self / foreigners experience geographical dislocations, which result in themselves being in foreign societies and cultures, namely Europe. This study examines Yusri Fajar's short stories and poetry in a travel literature framework as described by Carl Thompson. Thompson explained that there are three ways to see the travel literary pattern, namely by looking at the depiction of the world, self-disclosure, and other representations.
The results of his research are that the background of the self/foreign as an alienated person travels by force turns out to influence the travel literary pattern, namely in the depiction of the world, self-disclosure and other representations. From the literary pattern of the journey it can be seen that the self has a layered world, namely between Indonesia and Europe. The existence of this layered world at the same time indicates the problems experienced by the self/foreign, namely the problem of inferiority before the Europeans and the self/foreign desire for their homeland.

Introduction.In this study, we analysed the results of applying various surgical methods in the combined treatment of inflammatory diseases of bones and joints.

Materials and methods.The work was based on data from a multi-dimensional cohort study using non-concurrent (historical) control. A retrospective study included the analysis of medical records covering the period of 2009–2016 (1059 patients). A prospective study consisted in analysing the effectiveness of modern surgical methods in the combined treatment of inflammatory diseases of bones and joints in patients hospitalised to the Septic Surgery Department of the G.G. Kuvatov Republican Clinical Hospital (Ufa, Russia) in 2017–2018 (285 patients).

Results and discussion.An analysis of the authors’ own data revealed that injuries (73.21%) and infectious complications after receiving surgery on bones and joints (15.03%) are the most common causes of osteomyelitis. In most cases, the following list of measures is optimal for diagnosing suspected osteomyelitis of various etiologies: X-ray, general clinical tests supplemented by the fistulography or CT of the affected area prior to surgery, as well as the examination of surgical material after surgery. The use of modern methods for surgical debridement and surgical repair of bone defects in the combined treatment of patients with chronic osteomyelitis can significantly reduce the relapse rate. It is recommended that patients with osteomyelitis be treated at large in-patient surgical facilities, which include a specialised department for the treatment of surgical infections and corresponding support services.

Conclusion.Apparently, there is no one most optimal method for treating osteomyelitis. The optimal effect in the treatment of osteomyelitis is achieved through a personalised set of therapeutic measures using the following methods: laser vaporisation, negative-pressure wound therapy, ultrasonic cavitation in the focus of inflammation, as well as surgical repair of the post-trepanation bone defect or wound.

A manga é um fruto climatérico e durante a maturação está sujeita a uma série de alterações fisiológicas. Dentre as cultivares de manga que constituem a mangicultura Brasileira, a variedade ‘Ataulfo’, destaca-se por apresentar atributos sensoriais atrativos pelos consumidores norte-americanos. Recém introduzida no Vale do São Francisco, a cultivar ainda é pouco estudada quanto a maturação, sendo que inúmeras são as exigências dos países importadores de frutas de manga in natura em relação a qualidade do fruto. Portanto, objetivou-se neste estudo avaliar os atributos químicos de mangas da variedade ‘Ataulfo’ em diferentes estádios de maturação. Os frutos utilizados neste estudo foram adquiridos na fazenda CS Líder Agrícola, situada no município de Sento Sé/BA, selecionados e classificados e em três estádios (2, 3, e 4) de maturação comerciais. A polpa dos frutos foi avaliada quanto ao teor de: fibras alimentares; teor de água; teor de amido; atividade enzimática da enzima ?-amilase; teor de carboidratos totais; teor de açúcares; teor de proteínas; acidez titulável; e vitamina C. Observou-se que o teor de fibras e proteínas não apresentaram diferenças significativas ao decorrer da maturação dos frutos. Com o avanço da maturação houve aumento no teor de água e açúcares na polpa da manga ‘Ataulfo’, e ao mesmo tempo, houve redução no teor de amido, da atividade da enzima ?-amilase, o teor de ácidos orgânicos, e de vitamina C, e degradação da clorofila a e conversão em carotenoides e antocianinas durante o amadurecimento dos frutos de manga ‘Atulfo’.
Selection of the Most Stable Endogenous Control Genes for Microrna Quantitation in Chicken Ovarian Follicles
Authors: Ocłoń Ewa , Hrabia Anna
Published: November 2019

MicroRNAs (miRNAs or miRs) belong to a class of small non-coding RNAs of 19 to 24 nucleotides long that act as negative gene regulators at the post-transcriptional level. Quantitative PCR (q-PCR) is a commonly used technique in the profiling of miRs, and identification of reliable endogenous controls is crucial for proper data normalisation. To date, no study has been performed on reference miRs for the normalisation of miR expression in chicken ovarian tissues. Therefore, the aim of the present study was to experimentally identify the most stable reference mirs for normalisation of miR q-PCR expression data in the chicken ovary. Relying on high-throughput sequencing, five putative reference miR (let-7a-3p, miR-140a-3p, miR-22-5p, miR-33-5p, miR-99a-3p) were identified and subsequently analysed in a total of 66 tissue samples. The stability of candidate endogenous controls validated by the most widely used algorithms, geNorm, NormFinder, and BestKeeper, showed that let-7a-3p, miR-140a-3p, and miR-22-5p are the most appropriate choice of reference genes. Application of different normalisation approaches to the relative quantitation of randomly chosen miR-1552-5p in chicken ovarian follicles indicated the impact of the selected reference genes on miR expression. Further, the results revealed a downregulation of miR-1552-5p. In summary, the three identified endogenous reference miRs are suitable for profiling the miR expression in ovarian tissues of laying hens. Our findings provide valuable information for future miR expression studies in the avian ovary.

In this study, we investigated the influence of a silvopastoral system on the thermal environment, behaviour and thermoregulation of dairy heifers in a subtropical climate. The experiment was conducted on a dairy farm in Southwest Paraná, Brazil, during the summer of 2014. Crossbred Holstein × Jersey dairy heifers (n = 10) were used in a split-plot design. The fixed effects in this study include time of day (9:00–10:00, 13:00–14:00, and 17:00–18:00 h) under silvopastoral or open pastures conditions, which were the main-plot and split-plot factors, respectively. To assess the environmental conditions in both systems, air temperature, relative humidity and wind speed were recorded. In addition, the temperature-humidity index was calculated based on the microcli-mate measurements. Respiratory rate and hair coat surface temperature of heifers were measured in both groups during time of day (30 days). Diurnal behaviour using focal observations with 0/1 sampling was observed. Data were analysed using Bayesian inference with a mixed effects model. The air temperature was higher (P<0.05) in open pasture conditions than the silvopasture system. Temperature-humidity index values for the silvopasture system were lower than open pasture during the hottest hours of the day. Regarding thermoregulation responses, there was an interaction between time of day and pasture environment (P<0.05). Heifers showed lower respiratory rates and hair coat surface temperature values (P<0.05) when access to shade was provided, mainly during the hottest periods in the afternoon. In addition, there was also an interaction between rumination and water intake (P<0.05), which indicates a higher rumination frequency for animals in the silvopasture system during the hottest period, as well as a higher water intake frequency for heifers in open pasture during midday. These findings imply that the arrangement of trees in a silvopasture system provides better thermal comfort conditions for dairy heifers raised in a subtropical climate.

The length-weight relationship (LWR) parameters of Gobio insuyanus Ladiges, and Gobio microlepidotus Battalgil, which are endemic to Turkey, were estimated. The fish were caught by single-pass electrofishing with backpack electrofishing gear. The range for fork length and total weight and the LWR parameters including regression parameters (a, b, and their 95% CI) and the coefficient of determination (r
2) were calculated for both species. The b values were 2.921 for G. insuyanus and 2.906 for G. microlepidotus. The length-weight relationships were statistically significant for both species (P < 0.001). An urgent species conservation plan is highly recommended for G. insuyanus in light of its narrow distribution area and the human impacts threatening its natural habitat.
Using probiotics in freshwater larviculture
Authors: Kazuń Barbara , Kazuń Krzysztof
Published: November 2019

Probiotics have become a significant component of aquaculture in recent years. The use of antibiotics is decreasing successively because of their side effects in animals and their negative environmental impact, which is why alternative preventative measures are being sought. Probiotics that are effective in this field are playing increasingly important roles in safeguarding the health of fish and also as growth stimulants. The application of probiotics can help to successfully control the occurrence of disease in hatcheries, increase larval survival, and improve rearing parameters thanks to which the number of required brood-fish, which are expensive to maintain, can be reduced.
Distribution of epiphytic bryophytes in Wroclaw in relation to urban-use complexes
Authors: Fudali Ewa
Published: November 2019

Studies on epiphytic bryophyte species richness and diversity in various urban-use complexes in Wroclaw (excluding urban forests) were conducted in 2013-2016 to check the research hypothesis that, in spite of the observed phenomenon of return of bryophytic epiphytes to cities, urban parks still favor species richness and the diversity of bryophytic epiphytes in built-up areas. Epiphytes (38 species) were recorded in all distinguished urban-use complexes but with strongly differentiated frequency, and 64% of all the trees colonized with epiphytes were situated either along streets or inside urban green areas (32% in each). It was shown that the highest species richness (89% of all the species found), bryophyte total coverage and values of the diversity indices referred to the latter complex. 20 species revealed preferences to occur mostly or exclusively on trees situated in urban parks. The second urban-use complex, which visibly affected the distribution of epiphytes, was the complex of streets; Tortula muralis occurred only on trees along streets and six other species occurred more frequently in these complexes than in others: Orthotrichum diaphanum, O. pumilum, O. pallens, Ceratodon purpureus, Syntrichia virescens, Bryum argenteum. In general, epiphytes – which were recorded on more than 20 trees – colonized a large number of phorophytes, from 12 to 33. They also showed some tendencies to occupy trunks of some host tree species more frequently than others. Detailed data are provided.
