As espécies de Paspalum L. (Poaceae) dos grupos Virgata e Quadrifaria no Brasil - Distribuição e ecologia
(1996-12-01)
The Brazilian species of Paspalum L. (Poaceae) groups Virgata and Quadrifaria are revised based on herbarium material and live specimens of recent collections. The Virgata taxa are P. wettsteinii, P. rufum, P. regnellii, ...
Methodological Proposal for the Analysis of Spatio-Temporal Variability of Forage Value on Paspalum quadrifarium-Dominated Grasslands
(American Association for Science and Technology, 2017-12)
The Flooding Pampa is a subregion of Argentina where there is a plant communitywhose physiognomy is defined by tall-tussock grasses dominated by Paspalumquadrifarium. The hypothesis is that their floristic diversity allows ...
The species of Paspalum L (Poaceae), groups Virgata and Quadrifaria, in Brazil - Distribution and ecology
(Inst Tecnologia Parana, 2014)
Trends in fragmentation and connectivity of Paspalum quadrifarium grasslands in the Buenos Aires province, Argentina
(PeerJ, 2019-02)
Background. Despite its wide distribution worldwide, only 4.6% of temperate grasslands are included within systems of protected areas. In Argentina, this situation is even more alarming: only 1.05% is protected. The study ...
Phylogenetic Relationships in the Genus Paspalum (Poaceae: Panicoideae: Paniceae): An Assessment of the Quadrifaria and Virgata Informal Groups
(American Society of Plant Taxonomists, 2009-03)
Paspalum, an American genus of the x = 10 Paniceae clade, includes about 330 species, four subgenera, and 27 informal groups. Within the genus, the Quadrifaria and Virgata groups are well-represented in South and Central ...
Fragment size, vegetation structure and physical environment control grassland functioning: a test based on artificial neural networks
(Wiley, 2013-07)
Questions: How do fragment-level characteristics affect remnant grassland functioning in a highly transformed landscape? Are artificial neural networks (ANNs) a better statistical tool to model variations in grassland ...
Growth of the wild potato Solanum commersonii (Solanaceae) among grass tussocks under different defoliation intensities = Crecimiento de la papa silvestre Solanum commersonii (Solanaceae) entre matas de gramíneas bajo diferentes intensidades de defoliación
(Asociación Argentina de Ecología, 2018)
Solanum commersonii is a wild potato, valuable as a socioeconomic resource for a breeding
program of feeding crops. In grasslands, this species grows associated to Paspalum quadrifarium, a forage
grass managed under ...
Banco de semillas del suelo en un pastizal de una reserve natural del Sistema de Tandilia (Buenos Aires, Argentina) invadido por Racosperma melanoxylon
(Asociación Argentina de Ecología, 2021-12)
La restauración de los pastizales naturales invadidos por especies vegetales exóticas depende de la composición del banco de semillas del suelo. Se analizó la composición del banco de semillas germinable del suelo en dos ...
Soil ecosystem function under native and exotic plant assemblages as alternative states in successional grasslands
(Elsevier, 2012-11-14)
Old fields often become dominated by exotic plants establishing persistent community states. Ecosystem function in such novel plant assemblages may differ widely from that in the alternative, native-dominated counterparts. ...
