“…Frahm et al (2003) muestran que en los bosques tropicales lluviosos el hábito epífito es el más rico en especies, un rasgo fuertemente asociado a los altos valores de humedad. Los troncos en descomposición también son un sustrato con características físicas y químicas únicas e idóneas para la proliferación de la flora briofítica (Pócs, 1982), lo que determina un hábito epixílico (Mägdefrau, 1982) que afecta los patrones de colonización y abundancia de las diferentes comunidades (Sastre-De Jesús, 1992).…”

En el presente trabajo se caracterizó la flora briofítica en troncos en descomposición en la estación meteorológica el Zafire, Amazonas-Colombia. Para ello se realizó un muestreode 100 unidades muestrales en 20 troncos en diferente estado de descomposición y en dos tipos de bosque (tierra firme y varillal inundable). Se reportan 120 especies, 81 hepáticas y 39 musgos, pertenecientes a 55 géneros (33 hepáticas y 22 musgos) y 21 familias (nueve hepáticas y 12 musgos). Se registran cuatro especies nuevas para el país, 25 para la amazonia colombiana y 41 para el departamento del Amazonas. En términos de riqueza total, el bosque de varillal presentó un valor mayor al de tierra firme. Sin embargo, estadiferencia no es significativa (Kruskal Wallis X2=0,199; p = 0,05);así mismo la diversidad fue mayor en el bosque de varillal inundable (Shanon = 3,93) en comparación con la del bosque de tierra firme (Shanon = 3,67). La composición de las comunidades de briófitos fue diferente entre los dos tipos de bosques (similitud igual a 40 %). En el estudio florístico de los dos tipos de bosques de la estación biológica, se evidenció una marcada dominancia de la familia Lejeunaceae, que representaron el 55,5 % de las hepáticas y el 37,5 % del total de las especies de briofitos.

Abstract. Decomposing wood forms the substrate for special lignicolous, hygrophilous, and sciophilous plant communities. In a moist tropical forest, vegetation on this substrate consists mostly of bryophytes. The material gathered from Mt. Meru and the Usambara Mts. in Tanzania comprises 102 taxa or genera of bryophytes. Of these 86 taxa are mosses and 16 hepatics. They were collected from a number of rotten logs at different stages of decay both in primeval and in cultivated forests. The bryophyte vegetation on these logs was examined by use of quadrats 20 x 20 cm. A total of 71 taxa occurred in 51 plots.In the Usambaras, 38 species of bryophytes were recorded and 73 on Mt. Meru, all on rotten wood. Within each of 16 study areas the smallest number of taxa observed was 5 and the highest 37 in the natural forest on the east slope of Mt. Meru. Only three genera of hepatics and three species of mosses occurred both in the Usambaras and on Mt. Meru. Most of the taxa on rotten wood are rare; 42% of them were found on only one plot. Similarity indexes show that the bryophyte associations on Mt. Meru and in the Usambaras and the associations in the natural forests and cultivated forests on Mt. Meru are very different. Associations on natural forests on the east and west slopes of Mt. Meru show some similarity. The bryophyte associations on rotten wood coincide with the altitudinal zonation of montane forests: the associations at different altitudes differ, as does the structure of the vegetation. The bryophyte taxa represent 9 different life forms, with the weft form most frequent. At low elevations in the Usambaras, weft and mat forms are most common, while in primeval forests on Mt. Meru no life form is dominant. In the highest montane forests more life forms occur than at lower elevations.Differences in the flora and vegetation of rotten wood of the 16 study areas can be explained by differences in the intensity of the study, by climatological parameters and soils, and for historical reasons.The results, although preliminary, seem to indicate that within rather short distances quite different floras and associations occur on rotten 140 wood in northeastern Tanzania. Moreover, the floras of planted monocultures are quite different from the floras of primeval forest. These facts must be considered in the planning for preservation of biological diversity.

A list of 401 citations pertaining to the ecology of tropical bryophytes and lichens is presented. The bibliography includes publications addressing the biology, ecology, natural history, and physiology of bryophytes and lichens, but generally eschews taxonomic and floristic papers. All citations have been verified, unless denoted with an asterisk (*). An appendix that groups citations by category is provided.
