The mossflora of Camiguin Island, Philippines and their floristic relations to some adjacent islands in the archipelago
No full textThe moss flora of Camiguin Island, based on a 2007 expedition conducted by the author, totaled 129 species in 66 genera and 29 families. This represents 17.36% of the 743 moss species and 26.83% of the 246 genera of mosses reported for the Philippines (Linis & Tan 2008). Of these, one taxon, Aerobryopsis cochlearifolia Dix., is reported for the first time in the archipelago. Floristically, Camiguin moss flora is identified more with Mindoro and Luzon within the Philippine archipelago. Likewise, the presence of moss taxa such as Glossadelphus hermaphroditus Fleisch. and Orthomnion javense (Fleisch.) T. Kop. highlights the role of Mindanao in enriching the moss flora of Camiguin Island. Finally, the importance of remaining forests on the island as a proposed protected area is discussed

Mosses of Gunung Halimun National Park, West Java, Indonesia
No full textTAN, BENITO C.; HO, BOON-CHUAN; LINIS, VIRGILIO; ISKANDAR, EKA A.P.; NURHASANAH, IPAH; DAMAYANTI, LIA; MULYATI,SRI; HAERIDA, IDA. 2006. Mosses of Gunung Halimun National Park, West Java, Indonesia. Reinwardtia 12(3): 205–214. –– 150 species of mosses in 74 genera and 25 families are reported for the first time from Gunung Halimun National Park (GHNP) in West Java. Three mosses are new to the Indonesia flora (Distichophyllum collenchymatosum, D. malayense and Fissidens kinabaluensis), and another four mosses represent new records for Java (Dicranodontium asperulum, Daltonia armata, Glossadelphus bilobatus and Syrrhopodon semiliber). In additions, seven can be classified as uncommon mosses in the Malesian region. This shows that the forests of GHNP deserve a high priority of protection not only for the island of Java, but also for Indonesia and Malesia as well. </p
Biogeography of Mindoro mosses
No full textThe moss flora of Mindoro Island was updated based on the 2004–2006 expeditions conducted by the author. The island’s moss flora now consists of 282 species in 128 genera and 39 families, which is higher than Palawan but far less than those of Luzon and Mindanao. Generally, the flora is most abundant in the eastern rainy part of the island, especially along mid-elevations on the east-facing slope of the central mountain range in the transition zone between montane and mossy forests. Moss diversity is also greater in riverine forests than in inland forests at low elevations. Only three moss taxa, Rhaccocarpus alpinus, Dicranoloma daymannianum and Distichophyllum noguchianum, have their Philippine range restricted to the island. Distichophyllum noguchianum is a Philippine endemic. Floristically, the Mindoro moss flora is identified more with Luzon within the Philippine archipelago, while its sharing of other widespread Malesian taxa reinforced its role as an integral component of the Malesian flora. Reports of taxa with Australasian affinity show growing evidence for a Gondwanan influence on the island moss flora, although a tenuous one. Likewise, the presence of moss taxa such as Acroporium johanneswinkleri, Cryptogonium phyllogonioides and Glyptothecium sciuroides in Mindoro, reinforce the important role of Palawan as link in the exchange of biota between Mindoro, Borneo and Peninsular Malaysia during the Pleistocene.
Finally, the importance of the island in enriching the Philippine flora and the necessity to protect its remaining forests are discussed
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Biogeographical notes on the moss floras of Bicol Peninsula in Luzon and the Catanduanes Islands, the Philippines
No full textSubstantial moss collections have been made in Bicol peninsula and neighbouring Catanduanes Island, which form a special focus in the southeastern part of Luzon, the Philippines\u27 largest island. Moss diversity in the study area has now increased to 124 genera and 292 species. As expected, the moss flora has a predominant Luzon character, wherein about 34 species (11.64%) are restricted to Luzon, while about 18 species (6.16%) are new to the study area. Three species: Phyllodon lingulatus (Cardot) W. R. Buck, Aerobryopsis leptosigmata (Mull. Hal. ex Broth. & Geh.) M. Fleisch., and Calyptothecium squarrosulum Nog. & B. C. Tan are restricted to the study area, while one species, Acroporium convolutum (Bosch & Sande Lac.) M. Fleisch., previously reported for the Philippines but without a documented locality, is reported here with a locality information. Calymperes couguiense Besch., Leptotrichella sumatrana (Dixon) Ochyra, Papillidiopsis macrosticta (Broth. & Paris) W. R. Buck & B. C. Tan, Physcomitrium sphaericum (C. F. Ludw.) Furnr., and Sematophyllum phoeniceum (Mull. Hal.) M. Fleisch. are new Philippine records
The mossflora in selected areas in Mt. Natib Complex, Bataan Province, Luzon Island, Philippines
No full textOne hundred fifty seven species of mosses under eighty one genera and twenty nine families were collected in selected sites in Mt. Natib Complex, Bataan Province, Luzon Island, Philippines during the span of 38 months from 1997 to 2000. The moss flora of Mt. Natib Complex is a component of the greater Luzon moss flora. About 124 (c. 79.0 %) out of the 157 species collected are already known from this island. Remaining species were found in smaller adjacent islands, and in the Visayas and Mindanao. Extra-Philippine distribution of the Mt. Natib moss flora fits well to Malesia with 46.5% of the species collected belonging to the region. Species of clearly Laurasian origin were small at 1.3%. No floristic influence from Australasia or Gondawanaland is evident. Six species comprising about 3.6% of total number of collected moss species in Mt. Natib Complex, namely, Leucoloma perviride, Macromitrium robinsonii, Jaegerina williamsii, Mastopoma robinsonii, Taxithelium robinsonii, and Warburgiella bistrumosa were endemic
Notes on the diversity and floristic affinity of mosses (Musci, Bryophyta) from Zambales Mountain range, Luzon Island, Philippines
No full text© 219 Magnolia Press. The moss flora of Zambales Mountain Range of Luzon Island, Philippines is updated based on recent and herbarium collections and is found to consist of 268 species in 126 genera. The Zambales collections yield Ectropothecium sp., a probable new species and six new records for the Philippine moss flora: Ectropothecium callichroides, E. filicaule, E. planulum, Neckeromnion calcutense, Papillidiopsis stissophylla, and Splachnobryum oorschotii. Likewise, Gammiella tonkinensis, Gymnostomiella longinervis, Leucobryum arfakianum, and Rhaphidostichum bunodicarpum are new records for Luzon Island. Additionally, the affinity of mosses in Zambales Mountain Range to other known floristically distinct areas and islands in the archipelago is discussed
A review of intra-Philippine distribution patterns of Philippine mosses based on recent evidence of tectonic evolution of the archipelago: Insights and problems
No full textA recent review of the distribution patterns of Philippine mosses is presented. Interpretation about the distribution of local moss flora through correlation with information from the latest plate tectonic history of the archipelago, which has its beginning from the Oligocene period, is discussed. Long distance and chance dispersal as alternative explanations for local moss distribution are also supported
