El Toro Wilderness, Luquillo Experimental Forest, Puerto Rico

Weaver Abstract—The El Toro Wilderness, designated by Congress in 2005, man and his own works dominate the landscape, is hereby occupies about 36 percent of the 11,300 ha Luquillo Experimental recognized as an area where the earth and its community of Forest (LEF) in northeastern Puerto Rico.

Abelleira Martı´nez2 1 Biology Department, University of Puerto Rico, Mayagu¨ez Campus, PO Box 9000, Mayagu¨ez, Puerto Rico, 00681 2 International Institute of Tropical Forestry, USDA Forest Service, Ceiba 1201, Jardı´n Bota´nico Sur, Rı´o Piedras, Puerto Rico, 00926-1119 ABSTRACT The introduced tree species Spathodea campanulata (Bignoniaceae) forms novel forests in Puerto Rico, these having emerged after the abandonment of fields in the mid-20th century and resulting in forests with a new species composition. We assessed bryophyte species richness in these novel forests and sought correlations with geological substrate, past land use, forest edge and patch area, forest struc- ture, elevation, microhabitat diversity, tree species richness, and microclimatic conditions. Transects were established (edge and forest interior) in nine moist forest patches dominated by Spathodea in north-central Puerto Rico. These Spathodea forest patches ranged from 0.6 to 9 ha. ANOVA, Chi-square, correlation, and cluster analyses were used in data analyses. We found 57 bryophyte species. There was a significant difference in bryophyte richness among patches. Those on karst exhibited highest bryophyte richness due to microhabi- tat diversity, past land use, and shorter hydroperiods. Alluvial sites scored lowest in bryophyte species richness, and forest structure was important for bryophyte communities on these sites. Significant differences in temperature, relative humidity, and light intensity were observed between edge and forest interior. -

KEY WORDS: Begoniaceae, Begonia , México, Central America, Colombia Continuing research with the Begoniaceae and preparation of the Begoniaceae for the Flora Mesoamericana has resulted in the recognition of a number of new species (Burt-Utley & Utley 1999; 2011), including the 10 that are described herein. One of these species, B. wilburi , is unique in Central America because of its potential dioecy and is only one of two species in the Flora with turbinate capsules.

Conservation of Begonia Germplasm Through Seeds: Characterization of Germination and Vigor in Different Species
CONSERVATION OF BEGONIA GERMPLASM THROUGH SEEDS: CHARACTERIZATION OF GERMINATION AND VIGOR IN DIFFERENT SPECIES THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By: Steven Robert Haba, B.S. Graduate Program in Horticulture and Crop Science The Ohio State University 2015 Thesis Committee: Dr. Pablo Jourdan, Advisor Dr. Mark Bennett Dr. Claudio Pasian Dr. Mark Tebbitt Copyrighted by Steven Robert Haba 2015 ABSTRACT Begonia is one of the most speciose genera of angiosperms, with over 1500 species distributed throughout tropical and subtropical regions; it is also a very important ornamental group of plants displaying a high degree of morphological diversity. This genus is a priority for conservation and germplasm development at the Ornamental Plant Germplasm Center located at The Ohio State University, which currently holds approximately 200 accessions, maintained primarily as clonal plants. In an effort to expand germplasm work in seed storage of Begonia, and in response to a scarcity of published information about begonia seed biology we initiated a project to develop baseline information about germination, dormancy, and stress tolerance of begonia seeds. Because of the extremely small size of begonia seeds (ca. 200 µm) I adapted germination and viability testing protocols typical of Arabidopsis research, to develop relatively efficient quantitative protocols for seed studies. Using this methodology seeds can be routinely germinated on 1% agar plates at 25°C and 16 hours light. To examine the variation in seed characteristics among Begonia accessions in the collection, I selected six species from diverse environments and from different sections of the genus for which we had abundant seed and compared their germination patterns in response to temperature and light, tolerance to high humidity/high temperature stress, and dormancy. -
Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific
Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific Craig Costion School of Earth and Environmental Sciences Department of Ecology and Evolutionary Biology University of Adelaide Adelaide, SA 5005 Thesis by publication submitted for the degree of Doctor of Philosophy in Ecology and Evolutionary Biology July 2011 ABSTRACT This thesis advances plant biodiversity knowledge in three separate bioregions, Micronesia, the Queensland Wet Tropics, and South Australia. A systematic treatment of the endemic flora of Micronesia is presented for the first time thus advancing alpha taxonomy for the Micronesia-Polynesia biodiversity hotspot region. The recognized species boundaries are used in combination with all known botanical collections as a basis for assessing the degree of threat for the endemic plants of the Palau archipelago located at the western most edge of Micronesia’s Caroline Islands. A preliminary assessment is conducted utilizing the IUCN red list Criteria followed by a new proposed alternative methodology that enables a degree of threat to be established utilizing existing data. Historical records and archaeological evidence are reviewed to establish the minimum extent of deforestation on the islands of Palau since the arrival of humans. This enabled a quantification of population declines of the majority of plants endemic to the archipelago. In the state of South Australia, the importance of establishing concepts of endemism is emphasized even further. A thorough scientific assessment is presented on the state’s proposed biological corridor reserve network. The report highlights the exclusion from the reserve system of one of the state’s most important hotspots of plant endemism that is highly threatened from habitat fragmentation and promotes the use of biodiversity indices to guide conservation priorities in setting up reserve networks.
