Bryophytes are non-vascular plants, small green, simple, spore bearing and unique among plants in having relatively large, photosynthetic, and free living haploid gametophytes, and unbranched diploid sporophytes that remain attached to the maternal gametophyte throughout their life span, thus, it is heteromorphic in their life cycle (Azuelo et al, 2012). There are about 24,000 bryophyte species worldwide. One division is a Hepatophyta or the liverworts which are tiny land plants and there are approximately 8,500 species worldwide. These plants are easily overlooked because of their small sizes, yet play a very important role in the ecosystem. It is widely distributed, occurring from the arctic to the tropics. Some grow in relatively dry places and most occur where moisture is generally available, such as on damp soil or moist rotting logs, along shaded stream banks, on rocks in streams, or on wet rock outcroppings; a few even grow under saline conditions. The leafy and thalloid liverworts are the two groups of taxonomic characters. Furthermore, liverworts generally grow in consistently moist habitats, occupying niches where competition with vascular plants is minimal. Spray zones of waterfalls or wetlands such as bogs, fens, and streams seeps, are often rich in hepatics. Shaded old-growth forests also support liverwort growth, particularly in mesic or even hydric habitats. Thalloid liverworts grow on consistently damp rock faces or in wetlands. Other species may grow in shaded crevices and among mosses in more xeric conditions. Liverworts also may colonize moist or submerged rocks (Scapania nemorosa, Porella pinnata), grow under water (Ricciocarpus fluitans), found on logs and humic soil in mesic forests (Nowellia curvifloria, Bazzania trilobata) and grows on tree bark (Frullania eboracensis). Different forest associations favor a variety of liverwort assemblages (Schuster, 2000) Several liverworts species reported in traditional Chinese medicine such as Marchantia, Pallavicinia, Plagiochila and Lepidozia (Saxena and Harinder, 2004). Furthermore, liverworts also been considered to play a significant role in the global carbon budget (O’Neill, 2000) and CO2 exchange and have been used as indicator of past climate change, and as potential indicators of global warming (Gignac, 2001; De Lucia et al,2003). In the present study, the researchers attempted to assessed the number of liverworts that are distributed in the mossy forest of Mt. Kalatungan and possibly identify new possible species in the sites selected wherein the said mountain showed a very cold environment and are required as favorable condition to different bryophytes growing on tree trunks, soils and on rock moist surfaces within the study site. So far, very few studies have examined the liverworts community structure and its relationships to substrates and vegetation type, likewise, no central source towards synthesis of nomenclature, taxonomy, distribution patterns and conservation at a regional level, thus this present study is conceived.
Statement of the Problem
The study attempted to assess the distribution of liverworts in the mossy forest of Mt. Kalatungan, Bukidnon.
Specifically it sought to answer the following questions: 1. How are the species be classified, identified and described? 2.. How are the liverworts ecologically distributed in the mossy forest? 3. What are the species of liverworts identified with medicinal value?
Objectives of the Study
The study attempted to assess the liverworts in the mossy forest of Mt. Kalatungan, Bukidnon. Specifically, it aimed to:
1. Collect, identify and classify the liverworts at the study sites. 2. Determine how the liverworts ecologically distributed in the mossy forest. 3. Determine the species of liverworts...
