Bamboos belong to the grass family (or Poaceae). There are 1698 bamboo species distributed around world in tropical, subtropical and temperate jungles forests. In our country, there five native genera that comprise 23 species. The least known characteristic of woody bamboos is their flowering phenology. Four main types patterns have been described. However, most interesting those show a massive cyclical pattern, after long period vegetative growth. Such mass events occur at roughly regular...
Chusquea Kunth (Poaceae, Bambusoideae, Bambuseae) is the largest bamboo genus in world.Approximately 13 species of occur southern Andes Argentina and Chile all them are endemic.In present work, two new found high-altitude grasslands mountain range northwestern Argentina, egluma floribunda, described illustrated.Morphological anatomical characters identification keys for Andean from provided, one based on morphological (vegetative reproductive), other (culm leaf epidermis cross section).The...
Chusquea Kunth and Rhipidocladum McClure species (Poaceae, Bambusoideae, Bambuseae) are the only two genera of woody bamboos whose distributions reach southernmost portion Andes mountain range.The identification relies mainly on vegetative characters.In present work, foliage leaf blade anatomy Andean bamboo occurring in Argentina neighboring areas is described.Eight surveyed: culeou
The present study describes and illustrates two new species of Chusquea subg. Platonia, C. parodii paucispiculata. laegaardii is cited for the first time in Bolivia asymmetrica Peru. Two keys identification species, mainly based on vegetative or reproductive characters, a comparative table with micromorphological diagnostic features foliage leaf blades are included. Finally, some remarks about characteristics phytogeographical regions ecology these given.
Abstract Flowering in bamboo is an unusual event. Documenting flowering individuals or populations provides valuable information about life cycles. Guadua trinii endemic to northeastern Argentina, southern Brazil, Paraguay and Uruguay. We here report the of this species native cultivated stands Argentina confirm its cycle be 30-33 years.
Chusquea (Poaceae, Bambusoideae, Bambuseae) is the most diverse genus of woody bamboos in world. In Andean Patagonian forests southern Argentina and Chile, several species are dominant components understory. argentina C. culeou fo. longiramea were described from that area on basis morphological characters. Some authors have considered to be a valid others treated this as synonyms culeou. This study contributes delimitation these taxa. Based morphology anatomy, we clarify differential...
Chusquea Kunth (Poaceae, Bambusoideae, Bambuseae) is the most diverse genus of woody bamboos in world. In southern South America, several species are dominant components understory and all them endemic to region. The taxonomic position some those has raised much controversy. this work, a comprehensive revision native Chile presented, including synonyms, descriptions, iconography, geographic distribution, habitat, phenology, common names, key for identification 13 taxa considered here (12 one...
The present paper describes and illustrates two new species of Chusquea subg.Magnifoliae in Peru, C. longipedicellata rugoloana.Keys for the identification species, based on vegetative reproductive characters, as well a comparative table with morphological diagnostic features are included.Additional micromorphological characters spikelets leaves considered, complete description foliar anatomy is presented.Also, some remarks about characteristics phytogeographical regions ecology these provided.
A new, narrowly endemic species from the Andean western slopes of central Peru, Chusquea limensis (Poaceae, Bambusoideae, Bambuseae), is described and illustrated. Identification keys a comparative table based on vegetative reproductive characters, including morphologically similar such as C. huantensis, inamoena, scandens tarmensis, well habitat geographical distribution notes, are included. Additionally, anatomical micromorphological characters culm foliage leaf blades new presented,...
A taxonomic revision of the genus Podagrostis (Griseb.) Scribn. & Merr. is presented, including two new combinations: P. meridensis (Luces) A. M. Molina Rúgolo and novogaliciana (McVaugh) Rúgolo. bacillata (Hack.) Sylvester Soreng constitutes a report for Colombia. Information regarding synonymy, geographical distribution, habitat, iconography, vernacular names provided along with complete illustrations list additional specimens examined. key identification species included as well...
Flowering in woody bamboos remains an intriguing, infrequent and unpredictable event. Bambusa vulgaris ʽVittata' is a bamboo species of Asian origin, which widely cultivated Argentina the world due to its various applications. However, there are no records flowering this entity place origin or cultivation. The goal present work report B. specimen, Buenos Aires, providing information images event illustration reproductive structures. New characters have been found differentiate taxon,...

Abstract We performed a phylogenetic analysis with estimated clade ages and an ancestral-range estimation focused on the Patagonian species of Chusquea, i.e. Chusquea culeou clade, to unravel their biogeographical history. Phylogenetic analyses were conducted sequence data from four plastid markers, using maximum parsimony Bayesian inference approaches. The complete sampling addition into framework revealed most likely origin evolutionary history clade. originated roughly 11.35 Mya, common...
Capuchin monkeys (Sapajus nigritus cucullatus) are the most omnivorous primates of New World. However, forest fragmentation and degradation may limit resources availability. This in turn can act synergistically with other factors, such as severe weather conditions potentially causing changes spatial distribution, behavior, diet. During field observations capuchin we recorded use bamboo patches refuge sites supplementary food sources. behavior was observed December 2021 fragmented...
Flowering in woody bamboos is an intriguing phenomenon. Documenting a flowering event provides valuable information about bamboo life cycles. Chusquea argentina species endemic to the Andean Patagonian beech forests of Argentina and Chile. We here report C. northwestern Argentinean Patagonia. provide map area indicating sites. Photographs showing details are presented. The epidemiological effects taken into consideration.
La floracion de un bambu es evento particular. El registro la una mata o poblacion aporta datos precisos sobre los ciclos biologicos.
