Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington Dec 2007

Classification And Biogeography Of Panicoideae (Poaceae) In The New World, Fernando O. Zuloaga, Osvaldo Morrone, Gerrit Davidse, Susan J. Pennington

Aliso: A Journal of Systematic and Floristic Botany

Panicoideae (Poaceae) in the New World comprise 107 genera (86 native) and 1357 species (1248 native). As circumscribed herein, Panicoideae include eight tribes: Andropogoneae, Arundinelleae, Centotheceae, Gynerieae, Isachneae, Paniceae, Steyermarkochloeae, and Thysanolaeneae. The two major tribes are Andropogoneae with 230 species (16.95% of all New World panicoids), and Paniceae with 1082 species (79.73%). Andropogoneae are divided into nine subtribes (Andropogoninae, Anthistiriinae, Coicinae, Germainiinae, Ischaeminae, Rottboelliinae, Saccharinae, Sorghinae, and Tripsacinae), while Paniceae are divided into seven subtribes (Arthropogoninae, Cenchrinae, Digitariinae, Melinidinae, Panicinae, Paspalinae, and Setariinae). Brazil is the center of diversity of New World panicoids with 741 species (54.6% of all …


Classification And Biogeography Of New World Grasses: Chloridoideae, Paul M. Peterson, J. Travis Columbus, Susan J. Pennington Dec 2007

Classification And Biogeography Of New World Grasses: Chloridoideae, Paul M. Peterson, J. Travis Columbus, Susan J. Pennington

Aliso: A Journal of Systematic and Floristic Botany

Subfamily Chloridoideae (Poaceae) in the New World includes 72 genera (61 native, 11 introduced), 678 species (607 native), and, including intraspecific taxa, 817 total taxa. The five largest genera are Muhlenbergia (147 species), Eragrostis (111), Sporobolus (76), Bouteloua (57), and Chloris (35). Three tribes are recognized in this study: Cynodonteae, Eragrostideae, and Zoysieae, with ten, three, and two subtribes, respectively. Cynodonteae, the largest tribe, comprise 58 genera and 451 species (67% of all New World chloridoids), including 25 genera (98 species, 22% of all New World Cynodonteae) with unknown affinities (incertae sedis). In Mexico, the USA, and Canada there are …


Classification And Biogeography Of New World Grasses: Anomochlooideae, Pharoideae, Ehrhartoideae, And Bambusoideae, Emmet J. Judziewicz, Lynn G. Clark Dec 2007

Classification And Biogeography Of New World Grasses: Anomochlooideae, Pharoideae, Ehrhartoideae, And Bambusoideae, Emmet J. Judziewicz, Lynn G. Clark

Aliso: A Journal of Systematic and Floristic Botany

Molecular data support Anomochlooideae and Pharoideae as the two most basal extant clades within Poaceae. Anomochlooideae are endemic to the New World and have two tribes and two genera including the widespread Streptochaeteae (3–4 spp.) and the critically endangered Anomochloeae (1 sp.) of coastal Bahia, Brazil. Pharoideae are pantropical with one tribe, three genera, and 14 species; all eight species of Pharus occur only in the New World. Bambusoideae and Ehrhartoideae are sister groups and together form a clade sister to Pooideae, although support for this set of relationships is low. Ehrhartoideae are a worldwide subfamily represented in the New …


Frogs Of The Genus Eleutherodactylus (Leptodactyl Idae) In The Cordillera Occidental In Peru With Descriptions Of Three New Species, Edgar Lehr, William E. Duellman Jun 2007

Frogs Of The Genus Eleutherodactylus (Leptodactyl Idae) In The Cordillera Occidental In Peru With Descriptions Of Three New Species, Edgar Lehr, William E. Duellman

Edgar Lehr

Three new species of Eleutherodactylus are described from the Rio Zana Valley in the Pacific versant of the Cordillera Occidental in the Departamento de Cajamarca, Peru. One of the species is a member of the Eleutherodactylus conspicillatus Group, and two are members of the Eleutherodactylus unstrigatus Group.We recognize 15 species of Eleutherodactylus in the Cordillera Occidental; 10 of these species are reported for the first time from the Cordillera Occidental. Four of these species are shared with the Cordillera Occidental in Ecuador, and five are shared with the Cordillera de Huancabamba in northern Peru.


Asiatic Wild Ass In Israel, David A. Blank Jan 2007

Asiatic Wild Ass In Israel, David A. Blank

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The Syrian wild ass (Equus hemionus hemippus) lived in Israel in historic times until the 1930s, when it disappeared from the entire Middle East region. Khulans from other subspecies (E. h. onager - six individulas and E. h. kulan - five individuals) were brought to Israel from European zoos during 1968-69 (the authors of project considered that onager and kulan were the same subspecies) and these animals bred together in the semi-captivity conditions of the Haibar Yotvata Reserve. Later, during a 12-year period from 1982 through 1993, six groups totalling 38 khulans (17 males and 21 females) …


The Emerging Dziggetai (Equidae: Equus Hemionus Pallas): An Illustrated History Of Taxonomic Concepts For The Identification, Classification, And Distribution Of Hemiones From Central Asia, Arnd Schreiber Jan 2007

The Emerging Dziggetai (Equidae: Equus Hemionus Pallas): An Illustrated History Of Taxonomic Concepts For The Identification, Classification, And Distribution Of Hemiones From Central Asia, Arnd Schreiber

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The history of the discovery and the exploration of the hemione populations (Equus hemionus PALLAS) from Central Asia (Mongolia, northwest China, northeast Tibet, Kazakhstan, and Russian Siberia) from the 13th century to approximately 1950 are compiled with the aim to provide materials for a taxonomic and population genetic revision of the dziggetais. Data on their phenotypic differentiation, historical distribution status, and their husbandry history in European zoological gardens, are reviewed, as is the gradual emergence of concepts of how to identify and to classify these populations. Hemiones were an important historical case in the discussion of how to represent …
