New record of moss and thermophilic bacteria species and physico-chemical properties of geothermal soils on the northwest slope of Mt. Melbourne (Antarctica)
TLDR
It was concluded that physico-chemical features of geothermal grounds may affect the colonisation history and dispersal of microorganisms and mosses. Expand
Use of epidermal characters as bioindicators of environmental pollution Uso de caracteres epidérmicos como bioindicadores en contaminación ambiental
The present study explores the use of micromorphological leaf epidermal characters of Ficus benjamina (evergreen) and Fraxinus pennsylvanica (deciduous) as indicators of pollution in the MetropolitanExpand
Phenetic patterns in Poa section Dioicopoa: a new species from the Puneña and Altoandina phytogeographical provinces of Argentina
TLDR
The ligule length, plant size, and glabrous pistillate anthoecia distinguish Poa nubensis, a new dioecious species of Poa from the Punena and Altoandina phytogeographical provinces of Argentina. Expand
Leaf anatomy and biomineralization in Empetrum rubrum Valh ex Willd. (Ericaceae)
TLDR
The comparison between the characters described for this species and those from macroremains and phytoliths recovered from surface soils provides valuable tools for taxonomical, ecological, paleontological and paleoecological studies. Expand
Plant and soil phytolith analysis of a relictual community of Butia yatay in temperate-humid savannas (Entre Ríos, Argentina)
TLDR
Phytolith assemblages provide an important record for the characterization of the plant-soil system and production-incorporation system in mixed communities as a tool in the construction of palm trees paleoenvironments. Expand
Microbial populations and ruminal fermentation of sheep and llamas fed low quality forages
TLDR
The llama forestomach content showed higher degree of fermentative activity than the sheep one, as indicated by NH3-N and VFA values, and the forestomach of llamas contained higher density of total protozoa and Eudiplodinium. Expand

Phytolith analysis of the main species of Distichlis sp. (Chloridoideae: Poaceae) distributed in South America
TLDR
The results not only allowed us to identify the Distichlis species, but also to distinguish them from other grasses, including those in their subfamily; and represent a potential tool to identified halophytes environments outside New World saltgrasses. Expand
