The Vegetation of Robinson Crusoe Island (Isla Masatierra), Juan
The Vegetation ofRobinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile1 Josef Greimler,2,3 Patricio Lopez 5., 4 Tod F. Stuessy, 2and Thomas Dirnbiick5 Abstract: Robinson Crusoe Island of the Juan Fernandez Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation ofresources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accu rate assessment of the composition and structure of plant communities was made. We analyzed the vegetation with 106 releves (vegetation records) and subsequent Twinspan ordination and produced a detailed colored map at 1: 30,000. The resultant map units are (1) endemic upper montane forest, (2) endemic lower montane forest, (3) Ugni molinae shrubland, (4) Rubus ulmifolius Aristotelia chilensis shrubland, (5) fern assemblages, (6) Libertia chilensis assem blage, (7) Acaena argentea assemblage, (8) native grassland, (9) weed assemblages, (10) tall ruderals, and (11) cultivated Eucalyptus, Cupressus, and Pinus. Mosaic patterns consisting of several communities are recognized as mixed units: (12) combined upper and lower montane endemic forest with aliens, (13) scattered native vegetation among rocks at higher elevations, (14) scattered grassland and weeds among rocks at lower elevations, and (15) grassland with Acaena argentea. Two categories are included that are not vegetation units: (16) rocks and eroded areas, and (17) settlement and airfield. Endemic forests at lower elevations and in drier zones of the island are under strong pressure from three woody species, Aristotelia chilensis, Rubus ulmifolius, and Ugni molinae. The latter invades native forests by ascending dry slopes and ridges. -
"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -

Evolution of the Ovenbird-Woodcreeper Assemblage (Aves: Furnariidae) Б/ Major Shifts in Nest Architecture and Adaptive Radiatio
JOURNAL OF AVIAN BIOLOGY 37: 260Á/272, 2006 Evolution of the ovenbird-woodcreeper assemblage (Aves: Furnariidae) / major shifts in nest architecture and adaptive radiation Á Martin Irestedt, Jon Fjeldsa˚ and Per G. P. Ericson Irestedt, M., Fjeldsa˚, J. and Ericson, P. G. P. 2006. Evolution of the ovenbird- woodcreeper assemblage (Aves: Furnariidae) Á/ major shifts in nest architecture and adaptive radiation. Á/ J. Avian Biol. 37: 260Á/272 The Neotropical ovenbirds (Furnariidae) form an extraordinary morphologically and ecologically diverse passerine radiation, which includes many examples of species that are superficially similar to other passerine birds as a resulting from their adaptations to similar lifestyles. The ovenbirds further exhibits a truly remarkable variation in nest types, arguably approaching that found in the entire passerine clade. Herein we present a genus-level phylogeny of ovenbirds based on both mitochondrial and nuclear DNA including a more complete taxon sampling than in previous molecular studies of the group. The phylogenetic results are in good agreement with earlier molecular studies of ovenbirds, and supports the suggestion that Geositta and Sclerurus form the sister clade to both core-ovenbirds and woodcreepers. Within the core-ovenbirds several relationships that are incongruent with traditional classifications are suggested. Among other things, the philydorine ovenbirds are found to be non-monophyletic. The mapping of principal nesting strategies onto the molecular phylogeny suggests cavity nesting to be plesiomorphic within the ovenbirdÁ/woodcreeper radiation. It is also suggested that the shift from cavity nesting to building vegetative nests is likely to have happened at least three times during the evolution of the group. -

PRUM NaturalHistory Museum and Department of Ecologyand Evolutionary Biology, University of Kansas,Lawrence, Kansas66045, USA ABSTRACT.--Wereviewed the tremendousarchitectural diversity of ovenbird(Furnari- idae) nestsbased on literature,museum collections, and new field observations.With few exceptions,furnariids exhibited low intraspecificvariation for the nestcharacters hypothe- sized,with the majorityof variationbeing hierarchicallydistributed among taxa. We hy- pothesizednest homologies for 168species in 41 genera(ca. 70% of all speciesand genera) and codedthem as 24 derivedcharacters. Forty-eight most-parsimonious trees (41 steps,CI = 0.98, RC = 0.97) resultedfrom a parsimonyanalysis of the equallyweighted characters using PAUP,with the Dendrocolaptidaeand Formicarioideaas successiveoutgroups. The strict-consensustopology based on thesetrees contained 15 cladesrepresenting both tra- ditionaltaxa and novelphylogenetic groupings. Comparisons with the outgroupsdemon- stratethat cavitynesting is plesiomorphicto the furnariids.In the two lineageswhere the primitivecavity nest has been lost, novel nest structures have evolved to enclosethe nest contents:the clayoven of Furnariusand the domedvegetative nest of the synallaxineclade.

Most of the 600 species (in seven families and 13 genera) are arbo- rescent, but considerable morphological variability exists, spanning the giant scaly tree ferns (Cyatheaceae), the low, erect plants (Plagiogy- riaceae), and the diminutive endemics of the Guayana Highlands (Hymenophyllopsidaceae). In this study, we investigate phylogenetic relationships within tree ferns based on analyses of four protein-coding, plastid loci (atpA, atpB, rbcL, and rps4). Our results reveal four well-supported clades, with genera of Dicksoniaceae (sensu Kubitzki, 1990) interspersed among them: (A) (Loxomataceae, (Culcita, Pla- giogyriaceae)), (B) (Calochlaena, (Dicksonia, Lophosoriaceae)), (C) Cibotium, and (D) Cyatheaceae, with Hymenophyllopsidaceae nested within. How these four groups are related to one other, to Thyrsopteris, or to Metaxyaceae is weakly supported. Our results show that Dicksoniaceae and Cyatheaceae, as currently recognised, are not monophyletic and new circumscriptions for these families are needed. © 2006 Elsevier Inc. -

Tree Fern (Dicksoniaceae and Cyathaceae) Allelopathy in the Monteverde Cloud Forest Katie Heckendom and Melody Saeman
Tree fern (Dicksoniaceae and Cyathaceae) Allelopathy in the Monteverde Cloud Forest Katie Heckendom and Melody Saeman Albertson College of Idaho University of Wisconsin-Madison _____________________________________________________________ ABSTRACT The purpose of this experiment was to look at the effects of Allelopathy between six species of tree ferns in the Monteverde Cloud Forest. We analyzed these effects by comparing plant abundances under the tree ferns to controls. We also compared controls to germination of seeds and spores grown with water or leachate made from the tree fern fronds. We found significantly higher plant abundances in controls than under the tree ferns. Also significantly less seed and spore germination than controls was found. There was not a significant difference between species of tree ferns in their inhibition of plants under the tree ferns. We did observe a difference in allelopathic effects on germinating tomato seeds and Dicksonia gigantea spores, though not for Lophosoria quadripinnata spores. These results lead us to conclude that Allelopathy in nature is affected by other factors such as facilitation or competition but different species of tree ferns do show differing levels of Allelopathy. Allelopathy in tree ferns inhibits spores more than seeds indicating that more closely related species inhibit each other more, at least in this case. Also we confirmed previous studies that found Allelopathy in tree ferns. RESUMEN El propósito de nuestro experimento debía mirar los efectos de alelopatía entre seis especies de helechos arborecentes. En el Bosque de Nube de Monteverde.

Historical Reconstruction of Climatic and Elevation Preferences and the Evolution of Cloud Forest-Adapted Tree Ferns in Mesoamerica
Historical reconstruction of climatic and elevation preferences and the evolution of cloud forest-adapted tree ferns in Mesoamerica Victoria Sosa1, Juan Francisco Ornelas1,*, Santiago Ramírez-Barahona1,* and Etelvina Gándara1,2,* 1 Departamento de Biología Evolutiva, Instituto de Ecología AC, Carretera antigua a Coatepec, El Haya, Xalapa, Veracruz, Mexico 2 Instituto de Ciencias/Herbario y Jardín Botánico, Benemérita Universidad Autónoma de Puebla, Puebla, Mexico * These authors contributed equally to this work. ABSTRACT Background. Cloud forests, characterized by a persistent, frequent or seasonal low- level cloud cover and fragmented distribution, are one of the most threatened habitats, especially in the Neotropics. Tree ferns are among the most conspicuous elements in these forests, and ferns are restricted to regions in which minimum temperatures rarely drop below freezing and rainfall is high and evenly distributed around the year. Current phylogeographic data suggest that some of the cloud forest-adapted species remained in situ or expanded to the lowlands during glacial cycles and contracted allopatrically during the interglacials. Although the observed genetic signals of population size changes of cloud forest-adapted species including tree ferns correspond to predicted changes by Pleistocene climate change dynamics, the observed patterns of intraspecific lineage divergence showed temporal incongruence. Methods. Here we combined phylogenetic analyses, ancestral area reconstruction, and divergence time estimates with climatic and altitudinal data (environmental space) for phenotypic traits of tree fern species to make inferences about evolutionary processes Submitted 29 May 2016 in deep time. We used phylogenetic Bayesian inference and geographic and altitudinal Accepted 18 October 2016 distribution of tree ferns to investigate ancestral area and elevation and environmental Published 16 November 2016 preferences of Mesoamerican tree ferns. -
