Epilist 1.0: a Global Checklist of Vascular Epiphytes
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 EpiList 1.0: a global checklist of vascular epiphytes Zotz, Gerhard ; Weigelt, Patrick ; Kessler, Michael ; Kreft, Holger ; Taylor, Amanda Abstract: Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vas- cular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes evenwrong. -

Cactus Species Turnover and Diversity Along a Latitudinal Transect in the Chihuahuan Desert Region
Biodivers Conserv DOI 10.1007/s10531-007-9303-2 ORIGINAL PAPER Cactus species turnover and diversity along a latitudinal transect in the Chihuahuan Desert Region Héctor M. Hernández · Bárbara Goettsch · Carlos Gómez-Hinostrosa · Héctor T. Arita Received: 7 February 2007 / Accepted: 4 December 2007 © Springer Science+Business Media B.V. 2007 Abstract A standardized sampling method was used to evaluate turnover ( diversity) among cactus species assemblages along a 798 km long latitudinal megatransect across the Chihuahuan Desert Region, from north-central Mexico to southern Texas. A total of 71 cactus species were found along the megatransect, 66.2% of which appeared at low frequencies, mostly as a consequence of their highly discontinuous distribution pattern. At the scale the study was conducted, there was always species turnover among cactus assemblages. The rate of turnover among contiguous sites primarily Xuctuated from low to medium, but when all site combinations were considered (contiguous and non-contiguous), medium diversity values were predominant ( = 0.331–0.66); however, 25.4% of the site pair combinations registered high values ( = 0.661–1.0). Our results showed that turnover among cactus species assemblages in the CDR does not consist for the most part of a process of species succession in the geographic space. Instead, we concluded that the continuous spatial changes in cactus species composition are primarily explained by the commonly intermittent distribution patterns of the species, by the presence in the megatran- sect of species at the margin of their distribution range, and, to a lesser extent, by the existence of narrowly endemic species.

Floribunda Bahiensis AH307 Chapada Diamantina, Brazil
VOLUME 15 NUMBER 50 Floribunda bahiensis AH307 Chapada Diamantina, Brazil Photo - a -hofacker Uebelmannia flavispina Uebelmannia pectinifera PROBLEM UEBELMANNIAS From D.Angus Some years ago I bought one or two imported Uebelmannias which I tried to get established on their own roots. Although one of these plants was still with me after a year, the only way to describe my attempt to grow these plants is to say that it was a failure. Despite being careful with the watering and giving extra heat, they were all lost. Since then I have kept clear of Uebelmannias, until a couple of years ago when I obtained one or two grafted seedlings from a local grower. As soon as these plants got to a decent size they began to send down roots from the bottom of the graft. From my previous experience I did not want to take these plants off their graft and try to get them away on their own roots. So I reduced the length of the stock on U.flavispina to about one inch, and then got it rerooted. After that I cut down the length of stock on U.pectinifera and on U.pectinifera v.multicostata to a bare half an inch and they are now obviously re-rooted. I do not intend upsetting them by trying to find out if there is any of the original grafting stock left, or whether it has just dried away leaving the plant on its own roots. Even some of the offsets on these grafted Uebelmannias put down roots, so I have now removed two or three of these offsets and put them on a gritty compost on a heated bed, to see how they get on. -
Structure and Woody Species Diversity of the Dasylirion Cedrosanum (Nolinaceae) Rosette Scrub of Central and Southern Coahuila State, Mexico

Saltillo, Coahuila, Mexico 2Departamento de Ecología y Recursos Naturales, Facultad de Ciencias. Universidad Nacional Autónoma de México, México, Distrito Federal, Mexico 3Author for correspondence: [email protected] Abstract: The most prominent vegetation type in the state of Coahuila, in northern Mexico, is Chihuahuan Desert Scrub. This plant formation encompasses the little known Dasylirion cedrosanum (sotol) rosette scrub, a community that extends over more than one fourth of Coahuila and whose most distinctive species is subjected to intense extraction from its native communities for a variety of purposes. Based on a highly replicated sampling procedure that included 131 plots located in the state’s central and southern portions, we analyzed vegetation structure, fl oristics, and species diversity of this plant community. A cluster analysis allowed us to differentiate fi ve variants (associations) of the Dasylirion cedrosanum rosette scrub, which together host a richness of 97 species of vascular plants distributed in 61 genera and 28 families. These communities occurred across an elevational range of 850-2,550 m a.s.l. Dasylirion cedrosanum density varied between 193 and 705 ind./ha, with the highest value occurring in the Quercus intricata-Dasylirion cedrosanum association. Other prominent species in these scrublands were Agave lecheguilla and Euphorbia antisyphilitica. The Agave lecheguilla-Dasylirion cedrosanum association was the most broadly distributed and it hosted the highest richness species, while the largest Shannon diversity index value was recorded for the Dasylirion cedrosanum- Viguiera greggii association. -
STATUS of ORCHID TAXONOMY RESEARCH in the PHILIPPINES Review
Philippine Journal of Systematic Biology Vol. I, No. 1 (June 2007) Review STATUS OF ORCHID TAXONOMY RESEARCH IN THE PHILIPPINES Esperanza Maribel G. Agoo Biology Department, De La Salle University-Manila Orchidaceae is the largest of the monocotyledonous families in the Philip- pines. There are over 137 genera and about 998 species of orchids so far re- corded for the archipelago. This represents about 10% of the total flora of the Philippines. The Philippines ranks second to New Guinea in occurrence of en- demic species in the Malesian region. The monotypic endemic genera of orchids are Ceratocentron, Megalotus, Phragmorchis, and Schuitemania. Bogoria, Chelonistele, Lepidogyne, Omoea, Orchipedum are Malesian endemics repre- sented in the Philippines by one species each. The largest genera are Bulbophyllum (137 species), Dendrochilum (89 species), Dendrobium (85 species), Eria (54 species), Liparis (38 species), and Malaxis (33 species). Orchid collecting started in the Philippines as early as the Spanish times by Spanish missionaries like I. Mercado, G. Kamel, J. Blanco, Llanos, Fernandez- Villar, and Naves. Other notable collectors or expeditions were P. Sonnerat, T Haenke and L. Nee (Malaspina Expedition), A. von Chamisso (Romassoff), S. Perrottet (Le Rhone), H. Cuming, A. Loher, F.J.F. Meyen (Princess Louise of Prussia), C. Gaudichaude-Beaupre (La Bonite Expedition), Wilkes Expedition, and the Challenger. This was also the time when horticultural companies brought plants to Europe for trade (Mendoza, 1959). Collectors of the the Forestry Bureau in the 19th century, then the Bureau of Government Laboratories, and finally the Bureau of Science amassed a huge collection of specimens for the herbarium. -
