Abstract Aims We offer a first classification of South Brazilian grasslands ( Campos Sulinos ) based on quantitative vegetation data and describing grassland types in terms dominant indicator species. Location (Paraná, Santa Catarina, Rio Grande do Sul states). Methods described plots 167 sampling units throughout the region using stratified nested design, totalizing 1,502 1 m² quadrats. classified cluster analysis Bray–Curtis dissimilarities, establishing three ten subtypes. conducted...
Effective scientific efforts and conservation actions transcend political boundaries, encompassing entire ecological units. We compiled a vascular plant species list for the Río de la Plata grassland ecoregion, one of largest continuous ecosystems, in Americas. Our is based on existing regional lists, online databases published literature, taxonomically verified complemented by additional information distribution three countries (Argentina, Brazil Uruguay) origin species. 4864 accepted names...
Abstract The Conyza genus includes nearly 150 species, comprising closely related weedy species. Proper identification of spp. is essential to develop effective strategies for their management. overlap traits, species varieties, and the putative occurrence hybridization hampers its management in agricultural natural environments. Herein, we assessed five DNA barcodes 32 morphological traits classify survey dispersion soybean fields [ Glycine max (L.) Merr.] Brazil 2019, 2020, 2021....
Abstract Natural grasslands, one of the main ecosystems worldwide, are under threat and native species desired when addressing restoration issues. The processes for grasslands success plant establishment seed addition in soil. Thus, it requires overcoming barriers that prevent germination dispersal strategies. This study aimed to assess potential, treatments overcome dormancy endozoochory forage by cattle. Seeds from 21 four most common botanical families (Poaceae, Asteraceae, Fabaceae...
The aim of this study was to characterize the microsculpture cypselae surface Brazilian species Baccharis L. sect. Caulopterae DC. (Asteraceae), and compare data it with taxonomy group. Scanning electron microscopy used examine cypsela 25 taxa from Brazil. According micromorphology surface, can be classified into five distinct groups. trimera complex (B. crispa, B. cylindrica, jocheniana, myriocephala, trimera) share same micromorphological features.
Abstract A new species of Chevreulia (Asteraceae: Gnaphalieae) from southern Brazil is described in this work. revoluta A. Schneid. & R. Trevis. characterized by leaves larger than seven mm long, opposite, divergent, linear, with upper surface glabrous and rostrate cypselae. description provided as well a detailed illustration taxonomic comments. In addition an analytical key to distinguish the genus included.
A new species of Baccharis sect. Caulopterae endemic to rocky cliffs in southern Brazil, is here described as scopulorum. This characterized by the general presence basal and persistent leaves, mostly solitary capitula born at tips branches, many flowered capitula, pistillate with an urceolate campanulate involucres. The morphologically most similar B. altimontana opuntioides, both inhabiting mountain summits eastern Brazil. description scopulorum, together illustrations, a distribution map,...
Abstract Population genetic and ecological data may help to control invasive plants, which are considered a major threat natural habitats. In contrast expected bottleneck events, diversity of such populations be high due extensive propagule pressure or admixture. The impact species has been broadly evaluated in the field; however, long‐term studies on fate plants scarce. We analysed structure Spiraea tomentosa eastern Germany western Poland using Amplified Fragment Length Polymorphism....
Heiden G. & A. Schneider (2011). A new species of Baccharis sect. Caulopterae DC. (Asteraceae) from the high altitude grasslands Parque Nacional do Caparaó, Southeastern Brazil. Candollea 66: 337–340. In English, English and French abstracts.Baccharis hemiptera Schneid., a southeastern Brazil, is described, illustrated assigned to The close glaziovii Baker, south-eastern southern subalata Wedd., Bolivian Peruvian Andes.
A new species endemic to rocky cliffs in southern Brazil, Hysterionica matzenbacherii, is described. This characterized by leaves that are distally irregularly incised parted. It morphologically similar the Brazilian H. pinnatiloba and pinnatisecta its habit, capitula florets, but differs from them leaf features. description of matzenbacherii , together with illustrations, a distribution map, habitat description, conservation assessment diagnostic comparison other presented.
