The relative importance of local ecological and larger-scale historical processes in causing differences species richness across the globe remains keenly debated. To gain insight into these questions, we investigated assembly plant diversity Cerrado South America, world's most species-rich tropical savanna. Time-calibrated phylogenies suggest that lineages started to diversify less than 10 Mya, with diversifying at 4 Mya or less, coinciding rise dominance flammable C4 grasses expansion...
Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It an ecologically economically important group formed mostly woody perennials that range from large canopy emergent trees to functionally herbaceous geoxyles, lianas shrubs, which has a global distribution, occurring on every continent except Antarctica. Following recent re-circumscription 15 genera as presented in Advances Legume Systematics 14, Part 1, using basis phylogenomic...
Large genera provide remarkable opportunities to investigate patterns of morphological evolution and historical biogeography in plants. A molecular phylogeny the species-rich morphologically ecologically diverse genus Mimosa was generated evaluate its infrageneric classification, reconstruct a set characters, establish relationships Old World species rest genus.We used trnD-trnT plastid sequences for 259 (ca. 50% total) genus. Six characters (petiolar nectary, inflorescence type, number...
The legume genus Mimosa has > 500 species, with two major centres of diversity, Brazil (c. 350 spp.) and Mexico 100 spp.). In most species are nodulated by Burkholderia. Here we asked whether this is also true native endemic Mexican species. We have tested apparent affinity for betaproteobacteria examining the symbionts in Mexico, especially from central highlands where spp. diversified. Nodules were using situ immunolocalization. Rhizobia isolated nodules genetically characterized their...
Background: With 615 species worldwide, Mimosa is among the largest genera of Leguminosae family, and Mexico second center distribution genus after Brazil, with 105 species. In recent years, interest has arisen in morphological anatomical characters flower relation to floral visitors Mimosa. Questions: What relationship between inflorescence type, number arrangement flowers on axis? are whorls that distinguish species? Which pollen-stigma relationship, how does it influence reproductive...
Abstract Recent studies have shown that Acacia is polyphyletic and must be split into five genera. Proposal 1584 would retypify : the type of Australian taxon A . penninervis conserved over current lectotype ( scorpioides ) an African taxon. We disagree with recommendation Spermatophyte Committee to endorse this proposal. Contrary Article 14.12 ICBN , no detailed case against conservation was presented in 1584. maintain there are strong arguments conservation, such as large number countries...
Mimosa tenuiflora (Willd.) Poir. is an important natural resource in Mexico, due to its diverse uses. However, seed germination, dissemination and seedling establishment of this species had not been studied up date. Fruits seeds were collected the State Chiapas, Mexico (S. L. Camargo el al. 118, U AMIZ). Germinatíon experiments carried out afier four years storage; I 935 sown Petri dishes containing moistened Wathman filter papero Optimum temperatures determined a gradíent 5-40 ° C, with...
Abstract In this paper we analyse six communities with seven Mimosa species in the Tehuacan-Cuicatlan valley, Mexico. All are endemic to Mexico and four valley. found (1) ‘matorral xerofilo’ (arid tropical scrub): calcicola, M. lacerata, luisana, polyantha purpusii, (2) ‘selva baja caducifolia’ (tropical deciduous forest): adenantheroides, texana var. filipes. Most of them occur similar soil environments, while calcicola establish particular conditions only luisana establishes two different...
Con el fin de determinar la diversidad especies Bruchidae del estado Tabasco, se realizaron colectas a través (1) muestras semillas secas, y (2) colecta manual directa. Un total 3578 ejemplares en 14 géneros 49 fueron registradas las cuales 37 son nuevas para Tabasco. De 35 plantas hospederas colectadas, nueve como asociadas. Se presenta una diagnosis clave con esquemas genitalia uchidae
As a result of taxonomic study the genus Mimosa L. for Flora de Nicaragua, Mesoamericana, and M6xico, six new combinations at infraspecific level, two names specific changes series category supraspecific are herein proposed. These taxa occur mainly in southeastern Mexico (states Veracruz, Tabasco, Oaxaca, Chiapas, Yucatan Peninsula) as well Central America. RESUMEN. Como uno los resultados del estudio taxon6mico g6nero para la Mesoamericana y MLxico, se proponen seis combinaciones nuevas...
It has been considered that Mimosa aculeaticarpa var. and M. luisana have the potential to restore temperate semi-arid environments, respectively. Mature seeds were collected from eight mother plants per taxon determine effects of scarification temperature on seed germination both taxa, define optimum for germination. To obtain a representative sample each taxon, with same weight size mixed. Five replicates 20 (100 taxon/temperature, plus control) established. The mechanically scarified...
This is the first study of exine ultrastructure to be performed in five endemic Mexican Mimosa taxa (M. pringlei var. pringlei, M. calcicola, spirocarpa, caerulea and sousae), one occurring Mexico Central America occidentalis), widely distributed throughout neotropics setosa paludosa), two South irrigua daleoides). pollen grains are associated polyads (12 grains), octads tetrads. Polyads members basal clade phylogeny (sect. Mimadenia) evince affinity with Piptadenia. Octads retained sect....
Abstract— The subfamily Caesalpiniodeae has been the subject of several recent taxonomic delimitations, placing Mimosa in what is recognized as “Mimosa clade.” Specifically, decades phylogenetic studies have conducted with regard to genus, but estimation divergence times some previously unanalyzed species was unknown and reconstruction ancestral morphological states date limited mapping characters on a tree. aim present study perform phylogeny based trnD 2 -trnT rpS16 cpDNA markers well 19...

Abstract Leaflet anatomy of 14 taxa in Mimosa sect. Batocaulon, series Quadrivalves is described for the first time, using cleared leaflets and light microscopy. Members have obliquely asymmetric, linear-oblong, narrowly elliptic, or oblanceolate with an eccentric primary vein. The venation pattern brochidodromous basal lateral veins. In nine loops become notably narrower distal portion (anisonerved loops). On basis vein size width, nature loops, are divided into two groups, one isonerved a...
La subfamilia es de distribución cosmopolita y está representada por cerca 500 géneros poco menos 14,000 especies, que habitan en todo tipo ambientes. Incluye una gran cantidad plantas útiles para el hombre, entre las alimenticias, forrajeras, maderables, ornamentales, medicinales, así como numerosos usos más
La diversidad morfológica del género Mimosa y su problemática taxonómica han propiciado la búsqueda de caracteres en otras fuentes evidencia como anatomía madera. Se realizó un estudio comparativo madera tres especies distribuidas México: M. arenosa, lacerata polyantha (Sección Batocaulon); primera amplia distribución vertiente Pacífico México, Nicaragua, Colombia, Venezuela Brasil; mientras que las dos son endémicas México. Del tallo individuos por especie se colectó una troza 80 cm largo,...
Antecedentes y Objetivos: Los estudios ecoanatómicos permiten estimar la respuesta de los taxa a distintos factores ambientales. Considerando relevancia biológica ecológica del género Mimosa, se estimaron las posibles respuestas adaptativas dos endémicos México, M. aculeaticarpa var. luisana, través un análisis ecoanatómico su madera, para evaluar resistencia tolerancia cambios en precipitación.Métodos: Se recolectaron tres árboles talla cobertura similar por taxon. cortaron cubos madera 1 ×...
Antecedentes y Objetivos: La clasificación infragenérica de Mimosa (Leguminosae) es compleja. distinción entre los taxa se basa en caracteres morfológicos anatómicos. Diversos autores mencionan que complejos estomáticos son útiles la taxonomía vegetal. En Mimosa, anatomía foliar un campo poco explorado, por lo desconocen más 90% sus taxa. Por anterior, el objetivo este trabajo fue determinar, con fines taxonómicos, tipo complejo estomático 24 presentes México.Métodos: Se seleccionaron...
Mimosa tejupilcana, a new species from the State of Mexico, is described and illustrated. It presently known only Municipios Valle de Bravo, Temascaltepec, Tejupilco Hidalgo, Amatepec. The referred to series Plurijugae that placed in sect. Mimosa. A key distinguish all other taxa series, as well similar M. adenantheroides, provided.
