Aquatic vascular plants of South Brazil: checklist and a comparative floristic approach Acta Botanica
Oliveira,Lukiel dos Santos; Andrade,Bianca Ott; Boldrini,Ilsi Iob; Moço,Maria Cecilia de Chiara.
ABSTRACT Aquatic ecosystems support species diversity, and knowledge of plant communities is essential for wetland conservation programs. This study provides a checklist of aquatic vascular plants of South Brazil and establishes their floristic affinities with bordering South America phytogeographical domains. The checklist was based on 52 sources, including 35 floristic lists, 17 regional taxonomic studies, and information from an electronic database on wetlands of South Brazil. Floristic similarities with published checklists for neighbouring regions were assessed. A total of 780 species distributed in 277 genera and 85 families of vascular plants were reported for South Brazil. Families with higher species richness were Cyperaceae (128), Poaceae (102),...

Composición de la dieta y conducta del pastoreo de terneras (Bos taurus x Bos indicus) en un sitio con vegetación secundaria en el norte de Veracruz Colegio de Postgraduados
Velázquez Martínez, Mauricio.
Se estudió el comportamiento del pastoreo, selección de la dieta y ganancia de peso de terneras (sin y con modelos sociales) en un sitio con alta diversidad de especies de plantas. El estudio se llevo acabo en un ecosistema tropical que contenía una mezcla de zacates, herbáceas hoja ancha, vegetación leñosa y semileñosa. Diez terneras Bos taurus x Bos indicus (6 a 8 meses de edad) fueron asignadas aleatoriamente a uno de dos tratamientos: terneras sin experiencia (T1; n=5) con peso de 131.4 ± 14.1 kg, y terneras sin experiencia (T2; n=5) con peso de 129.6 ± 6.4 kg acompañadas por dos modelos sociales (16 meses de edad) con peso de 153.3 ± 4.1. Cada grupo de animales pastorearon en potreros separados durante un periodo de 12 semanas, y los animales...

Diversidad funcional de los hongos micorrizógenos arbusculares de islas de recursos del Valle del Mezquital, Hidalgo. Colegio de Postgraduados
García Sánchez, Rosalva.
Este estudio se llevo a cabo en el Valle del Mezquital, Hidalgo, el valle se caracteriza por una cubierta vegetal secundaria y fragmentada, en donde se forman islas de recursos. Esta investigación evaluó el efecto de Prosopis laevigata y Mimosa biuncifera juntas y separadas, sobre la diversidad de especies arbustivas y propiedades del suelo. Se generó información sobre la riqueza y diversidad de hongos micorrizógenos arbusculares (HMA) asociados al suelo bajo dosel de P. laevigata y de M. biuncifera, presentes en tres matorrales con diferente predominio de leguminosa. En condiciones de invernadero, se evaluó el efecto de la procedencia de los HMA sobre el crecimiento de ambas leguminosas. Se reportaron 45 especies arbustivas en estos matorrales, destacaron...

Floristic and phytosociological analysis of palm swamps in the central part of the Brazilian savanna Acta Botanica
Resende,Isa Lucia de Morais; Chaves,Lázaro José; Rizzo,José Ângelo.
We analyzed the floristics and phytosociology of three palm swamps in the municipality of Bela Vista de Goiás, located in the state of Goiás, Brazil, in the central part of the Brazilian savanna (Cerrado). The floristic surveys were conducted monthly from May 2008 to April 2009, and 310 species were recorded (seven bryophytes, 15 ferns and 288 angiosperms). Bryophytes belonged to five genera and five families; ferns belonged to nine genera and nine families; and angiosperms belonged to 134 genera and 45 families. The angiosperm families with the highest species richness were Poaceae, Cyperaceae, Asteraceae, Eriocaulaceae, Xyridaceae, Lentibulariaceae, Melastomataceae, Rubiaceae and Fabaceae. The palm swamps were divided into three zones of increasing...

Importance of water quality on plant abundance and diversity in high-alpine meadows of the Yerba Loca Natural Sanctuary at the Andes of north-central Chile RChHN
GINOCCHIO,ROSANNA; HEPP,JOSEFINA; BUSTAMANT,ELENA; SILVA,YASNA; DE LA FUENTE,LUZ MARÍA; CÁSALE,JEAN FRANCOIS; DE LA HARPE,JEAN PAUL; URRESTARAZU,PAOLA; ANIC,VINKA; MONTENEGRO,GLORIA.
Porphyry Cu-Mo deposits have influenced surface water quality in high-Andes of north-central Chile since the Miocene. Water anomalies may reduce species abundance and diversity in alpine meadows as acidic and metal-rich waters are highly toxic to plants The study assessed the importance of surface water quality on plant abundance and diversity in high-alpine meadows at the Yerba Loca Natural Santuary (YLNS), central Chile (33°15' S, 70°18' W). Hydrochemical and plant prospecting were carried out on Piedra Carvajal, Chorrillos del Plomo and La Lata meadows the growing seasons of 2006 and 2007. Direct gradient analysis was performed through canonical correspondence analysis (CCA) to look for relationships among water chemistry and plant factors. High...

Relationship between fragmentation, degradation and native and exotic species richness in an Andean temperate forest of Chile Gayana Botánica
ROJAS,ISABEL; BECERRA,PABLO; GÁLVEZ,NICOLÁS; LAKER,JERRY; BONACIC,CRISTIÁN; HESTER,ALISON.
Human impact such as forest fragmentation and degradation may have strong effects on native and exotic plant communities. In addition, these human-caused disturbances occur mostly in lowlands producing greater fragmentation and degradation there than in higher elevations. Plant invasion should be greater in more fragmented and degraded forests and hence lowlands should be more invaded than higher elevations. In turn, native species richness should be negatively related to fragmentation and degradation and hence greater in higher elevations within a forest type or elevation belt. We assessed these hypotheses in an Andean temperate forest of southern Chile, Araucanía Region. We recorded the vascular plant composition in twelve fragments of different size,...

Social organization influences the exchange and species richness of medicinal plants in Amazonian homegardens Ecology and Society
Howard, Patricia L.; Department of Social Sciences, Wageningen University; Centre for Biocultural Diversity Studies, University of Kent; Patricia.Howard@wur.nl.
Medicinal plants provide indigenous and peasant communities worldwide with means to meet their healthcare needs. Homegardens often act as medicine cabinets, providing easily accessible medicinal plants for household needs. Social structure and social exchanges have been proposed as factors influencing the species diversity that people maintain in their homegardens. Here, we assess the association between the exchange of medicinal knowledge and plant material and medicinal plant richness in homegardens. Using Tsimane’ Amazonian homegardens as a case study, we explore whether social organization shapes exchanges of medicinal plant knowledge and medicinal plant material. We also use network centrality measures to evaluate people’s location...

Tree community variation in a tropical continental island according to slope aspect and human interference Anais da ABC (AABC)
GONÇALVES,NATHAN B.; NETTESHEIM,FELIPE C.; CONDE,MARILENA M.S..
ABSTRACT Associating description of unrecorded tropical tree community structure to sampling approaches that can help determine mechanisms behind floristic variation is important to further the comprehension of how plant species coexist at tropical forests. Thus, this study had the goals of (i) evaluating tree community structure on the continental island of Marambaia (23°4’37.09”S; 43°59’2.15”W) and (ii) testing the prediction that there are local scale changes in a tropical tree community structure between slopes facing different geographic orientation and with distinct human interference history. We established 60 (0.6 ha) sampling units in three different slope sites with distinct predominant geographic orientation and human interference. We sampled...
