Epiphytiology

The dynamics of epiphytic bryophyte communities following natural and human disturbance have rarely been quantified. We describe the response of bryophyte communities on bigleaf maple trees (Acer macrophyllum Pursh) in Olympia, Washington, following their experimental removal. Approximately 8% of the exposed area was recolonized by bryophytes 1 year after clearing, and 27% after 3 years. Lateral encroachment from bryophytes on the sides of the 20-cm-long plots accounted for 75% of this recolonization, with growth from residual plant parts or aerially dispersed diaspores accounting for the remaining 25%. Though it was not possible to distinguish between the latter two sources of cover, the number of clear de novo colonization events over the course of the year was low (0.18 dm-2). Disturbance appeared to reduce bryophyte diversity at this successional stage, as alpha and gamma diversity remained low after 1 year and had not recovered after 3 years. Reflecting the preponderance of lat...

O diagnóstico ambiental de três fragmentos de mata ciliar nos trechos superior (CA), médio (TA) e inferior (CB) do Rio dos Sinos, no sul do Brasil, foi realizado a partir de uma análise integrada de parâmetros botânicos, meteorológicos e da genotoxicidade do ar atmosférico. A análise demonstrou que em CA a mata ciliar apresentou um maior número de árvores, mais altas, com maior área basal, suportando uma riqueza epifítica maior. Além disso, a genotoxicidade do ar e o volume de precipitação de chuva foram superiores a TA e CB. Considerando que as respostas dos organismos são influenciadas pelas condições ambientais, os indicadores analisados sustentam a ideia de que a mata ciliar de CA ainda é uma área de referência, evidenciada principalmente pela elevada riqueza de epífitos vasculares incluindo espécies sensíveis às perturbações antrópicas, e pela ausência de risco genotóxico.

The evaluation of the mutagenic potential of the environment can be performed through the analysis of meiotic alterations observed in Tradescantia pallida cv purpurea, commonly used as a bioindicator of genetic damage caused by environmental factors. The objective of this research was to evaluate the influence of air pollution and solar radiation on the frequency of chromosomal abnormalities in tetrads of Tradescantia. Inflorescences were collected from plants grown in contrasting conditions: exposure to sun and shade and cultivation in light and heavy vehicular traffic. It was observed that higher rates of meiotic abnormalities were found in plants exposed to the sun and heavy traffic conditions. The lowest values were obtained in samples collected from plants exposed to conditions of shade and light traffic. It was noted that the effect of the light intensity in the formation of micronuclei was greater than the effect due to vehicular traffic. However, it was noted that the mean number of micronuclei per tetrad abnormal was higher in plants grown under conditions of high vehicle traffic compared with plants grown under conditions of light automotive traffic.

ABSTRACT: (Environmental diagnosis of the Rio da Ilha watershed, Taquara, Rio Grande do Sul, Brazil). The main objective of this study is to identify the potential environmental support for the implementation of sustainable tourism in a reference unit of the municipality of Taquara, Rio Grande do Sul. Analyses of water quality of the streams, fauna and flora inventory, and socioeconomic and environmental perception of the population were taken. Those analyses were made to create an environmental and partner-economic microzoning for the area of the hydrographic basin. The study identified a potential for the implantation of sustainable tourism in the region. Natural conditions exist, but land use and ecological patterns and processes have to be understood. Taquara is included in the Atlantic Forest area, which is characterized by a great flora and fauna diversity. However, we can conclude that for the implementation of such tourism program, investments in public politics are needed.

RESUMO O potencial genotóxico dos elementos-traço cádmio (Cd) e chumbo (Pb) nas concentrações máximas permitidas no Brasil pelas Resoluções CONAMA nº 357/2005 (classificação de corpos d'água, água doce de classe I) e CONSEMA nº 355/2017 (emissão de efluentes líquidos em águas superficiais no Rio Grande do Sul) foi avaliado por meio do teste de micronúcleos (MCN) com o uso de Tradescantia pallida var. purpurea. Após 24 h de adaptação em água destilada, 20 ramos com botões florais foram expostos por 8 h em 2 L em água destilada com diferentes concentrações de Cd (0,001 e 0,1 mg L-1) e Pb (0,01 e 0,2 mg L-1), seguido da recuperação por 24 h em água destilada para finalizar o ciclo da meiose. Simultaneamente, foi realizado controle negativo com exposição dos ramos apenas em água destilada. Após, as inflorescências foram fixadas em etanol/ácido acético (3:1 v:v) por 24 h e armazenadas em etanol 70% sob refrigeração. As frequências de MCN nos botões florais expostos às concentrações de 0,001 mg L-1 e 0,1 mg L-1 de Cd não diferiram significativamente entre si (2,90 e 3,43 MCN, respectivamente), mas diferiram significativamente da frequência do controle (1,93 MCN) (p=0,006). Para Pb, as frequências de MCN nos botões florais expostos às concentrações 0,01 mg L-1 e 0,2 mg L-1 diferiram significativamente entre si (3,76 e 5,03 MCN, respectivamente) e do controle (1,93 MCN) (p<0,001). Os resultados indicam que as concentrações máximas de Cd e Pb permitidas pelas Resoluções CONAMA nº 357/2005 e CONSEMA nº 355/2017 são potencialmente genotóxicas. Palavras-chave: Genotoxicidade.

Vegetation studies to reveal tree diversity and its contribution to carbon stock were conducted in three different sites of upland forest in Bali, Indonesia. The sites were located approximately 60 km north of the Bali Province capital city of Denpasar in an area named Bedugul. Those three sites were Mt. Mangu (forest area east of Beratan lake), forest area west of Buyan lake and forest area south of Tamblingan lake. There were 44, 29, and 21 tree species of 14, 19, 14 families with Shannon Diversity Index (H') of 2.87, 2.64 and 1.69 respectively. Carbon stock average of above ground tree biomass from these sites were 214.2, 693.0 and 749.1 ton.ha-1 respectively. Tree species with top Summed Dominance Ratio (SDR) in each of those sites were Platea latifolia in Mt. Mangu, Planchonella sp. in Buyan, and Tabernaemontana macrocarpa in Tamblingan. Average carbon content of these three species were 493.25, 12,876.26 and 40.35 kg.ha-1 respectively.

Abstrak. Balanopohora elongata Blume merupakan tumbuhan holoparasit pada akar tumbuhan lain dan rimpangnya mengandung lilin lengket yang dimanfaatkan untuk penerangan. Tujuan dari penelitian ini adalah untuk mengetahui asosiasi B. elongata dengan tumbuhan bawah lainnya yang berada di hutan kawasan Kebun Raya Cibodas. Penelitian dilakukan pada bulan Januari-April 2016 di empat buah hutan sekunder yang ada di dalam kawasan Kebun Raya Cibodas menggunakan teknik petak disarangkan (nested pot technique). B. elongata yang dijumpai dalam penelitian ini menempel pada inang F. ribes dan S. pendula. Total ditemukan B. elogata sejumlah 186 individu dengan jumlah terbanyak dijumpai di Hutan Kompos. Pola dispersi dari B. elongata menunjukkan pola sebaran kelompok dengan nilai indeks dispersi Morisita 1,62. Sebanyak 45% tumbuhan bawah memiliki tipe asosiasi positif dengan B. elongata antara lain S. acuminatissima, Cyathea sp., Begonia multangula, Calathea lietzei, dan Euchresta horsfieldii. Dari 39 jenis tumbuhan bawah, hanya 2 jenis yang menunjukkan tidak adanya asosiasi yaitu D. febrifuga dan L. laevigatus sementara itu 37 jenis lainnya memiliki asosiasi dengan B. elongata dengan derajat asosiasi yang berbeda-beda. Banyaknya hubungan asosiasi menunjukkan B. elongata dapat hidup bersama dengan mayoritas tumbuhan bawah lainnya dan tidak memiliki preferensi khusus untuk berasosiasi. Kata kunci: Asosiasi; B. elongata; Kebun Raya Cibodas; tumbuhan bawah. Abstract. Balanopohora elongata Blume is a holoparasitic plant on plant roots and its rhizomes contain sticky wax that is used for lighting. The aim of this study was to determine the association of B. elongata with understorey vegetation in the Cibodas Botanic Gardens remnant forest. The study was conducted on January-April 2016 in four secondary forests using nested plot technique. The resuts was found total 186 individuals of B. elongata and it attached to the host F. ribes and S. pendula. Morisita dispersion index for B. elongata was 1.62. 45% of understorey vegetation has a positive association with B. elongata e.g. Schismatoglottis acuminatissima, Cyathea sp., Begonia multangula, Calathea lietzei, and Euchresta horsfieldii. Only two plant species that showed no association with B. elongata e.g. Dichroa febrifuga and Lasianthus laevigatus. While 37 plant species have associations with B. elongata with various associate degrees. It was indicated B. elongata could life together with majority of understorey vegetation and do not have a specific preference for association.

Mount Seblat, as part a of Kerinci Seblat National Park (KSNP), is a pristine and natural mountain, particularly from disturbances and destructions by human activities. Nevertheless, the richness of biological resources especially plants diversity.in this area has not been more explored. The purpose of this study was to conduct an inventory of plant diversity and to determine the plant species composition. The inventory activities were conducted by plants collection along the ascent route. The results were then be maintained through ex situ conservation method in Cibodas Botanical Garden (CBG). The study was conducted by an exploratory method, from Seblat Ulu Village (641 m asl) up to an altitude of 1,037 m asl. There were 18 points of plant sample observation with an area of 5 x 5 square meters per point. Plant collection obtained 380 specimens. Five groups of most collected plants were Lauraceae (18 species), Rubiaceae (8 species), Anacardiaceae (6 species), Annonaceae (5 species), and Fagaceae (4 species). In order to enrich the plant collection as well as conduct the ex situ conservation effort, plants from Orchidaceae were also collected which resulted in 33 species. These results were an important initial inventory of plant diversity of Mount Seblat, considering that there was no record as well as very limited current information. When the environment disturbance tends to increase, this information may act as a reference and an initial database to develop plants conservation effort and strategy in the future.

Abstract. Nasution T, Junaedi DI. 2017. Diversity and composition of vascular epiphytic plant on tree ferns (Cyathea spp.) at Cibodas
Botanic Garden, West Java. Pros Sem Nas Masy Biodiv Indon 3: 453-460.  Tree ferns are important horticultural commodities for
ornamental plant and planting medium. These  ferns are also ecologically important for  the habitat of vascular epiphytes. The
information on the relationship of tree ferns and vascular epiphytes is still limited, so that it is important to be studied for supporting its
management in Cibodas Botanic Garden. This study aimed to study the diversity and composition of vascular epiphytes on wild tree
ferns in Cibodas Botanic Garden. The census of vascular epiphytes on 30 individuals of Cyathea contaminans and 30 individuals of
Cyathea junghuhniana had been conducted. About 3,034 individuals of vascular epiphytes were recorded belongs to 138 species and 51
families. The species richness of vascular epiphytes on C. contaminans was 95 species and higher than C. junghuhniana (86 species).
The abundance of vascular epiphytes on C. contaminans was 1,820 individuals and higher than C. junghuhniana (1,214 individuals).
Shannon-Wiener  index of vascular epiphytes on  C. contaminans was 3.13 and lower than  C. junghuhniana (3.67). The species
composition of both hosts comprised 108 species of spermatophytes and 31 species of ferns.  The highest species richness on  C.
contaminans was Polypodiaceae, followed by Poaceae and Orchidaceae, whereas Moraceae, Polypodiaceae and Urticaceae were the
highest species richness on C. junghuhniana. The vascular epiphytes of tree ferns in Cibodas Botanic Garden had a relatively high
diversity. The management of tree ferns would support the conservation of vascular epiphytes in Cibodas Botanic Garden.
