Abstract Question What are the composition and spatial patterns of native woody plant communities in southern Great Chaco Espinal? Location Córdoba Province, central Argentina, an area ca . 161,000 km 2 Methods We collected 351 geo‐referenced relevés representative geographic, topographic ecological variation Espinal vegetation Argentina. The were classified into types using hierarchical ISOPAM method. Forest shrubland described on basis diagnostic species occurrences their distribution...
Abstract Aim Existing global models to predict standing biomass are based on trees characterized by a single principal stem, well developed in height. However, their use open woodlands and shrublands, multistemmed species with substantial crown development, generates high level of uncertainty estimates. This limitation led us (a) develop shrub individual aboveground simple allometric variables, (b) compare the fit these existing models, (c) assess whether change when bioclimatic variables...
AimsIncreasing evidence worldwide indicates that high mountain regions are not immune to invasion by alien plants. Here, we aimed address whether three major woody invaders of low-mountain areas constrained lower altitudes due climatic restrictions or just low propagule pressure. We hypothesize the increasing harshness towards higher restricts seedling establishment and survival these thus their potential for altitudinal expansion.
Abstract Fire frequency has been highlighted as an important component of fire effects on ecosystems; nevertheless, there is scarce information about how modulates changes in ecosystem properties, particularly for subtropical dry forests. A long‐term natural experiment and a multiscale approach were used to analyze properties forest subjected contrasting regimes. Measurements taken two adjacent sites that had regimes (low/high frequency), vegetation soil analyses combined with...
Aims : The native woody vegetation from the Espinal phytogeographic province in central Argentina, found subtropical-warm temperate climates, represents part of southernmost seasonally dry forest South America. Although this has been studied for over a century, complete phytosociological survey is still needed. This lack knowledge makes its spatial delimitation and establishment efficient conservation strategies particularly difficult. main goals study were to classify these forests assess...
In this study we assessed the water transport strategies and abundance of alien native tree species at a regional scale in Córdoba Mountains, Central Argentina. The aims were: (i) to analyse whether show divergent strategies; (ii) explore abundances natives are associated with specific trait attributes. Eight 12 were recorded 50 complete vascular plant vegetation relevés. Water through following functional traits: minimum leaf potential, potential content wood, effective area, area per...
Cacti are important elements of the flora in many ecosystems Americas. However, factors that determine their richness and composition not well known, particularly at regional scale. The aim this work was to study patterns cactus (both species growth forms) Sierras del Norte mountain range (Córdoba Province, Argentina). Species presence recorded 55 sites covering an altitudinal gradient from 203 970 m. Twenty four eight genera were area. Total form decreased with increasing altitude. columnar...
Abstract Aim Invasive species have the potential to alter hydrological processes by changing local water balance. However, general patterns of how rainfall is partitioned into interception, throughfall and stemflow for invasive worldwide been seldom explored. We (a) describe percentage woody plant species; (b) analyse influence morphological attributes (i.e. life‐form, bark roughness, leaf type, phenology area index) on partitioning; (c) compare partitioning fluxes co‐occurring native...
Aims : We address the following questions: 1) Which are main vegetation types that currently occur in Arid Chaco? 2) Do those differ terms of floristic composition, endemism, chorotypes and life forms? 3) Is there any spatial association between environmental heterogeneity Study area The southwestern extreme Gran Chaco, Central-Western Argentina. Methods survey was based on a dataset comprising 654 relevés collected according to Braun-Blanquet method. Data were classified by hierarchical...
Invasions by exotic woody species are threatening ecosystem functions worldwide. The spread and subsequent replacement of native forest dominated stands is particularly evident nearby urban centers were propagule pressure highest. Yet, there a lack information on the environmental factors that underlie these replacements. In this study we addressed following questions: (1) local spatial segregation between dominant species? (2) if does exist, it driven features? For this, in 2010 established...
Steep climatic gradients boost morphological and physiological adjustments in plants, with consequences on performance. The three principal woody species of the Sierras Grandes Mountains central Argentina have marked differences sapling performance along their altitudinal distribution. We hypothesize that steep gradient conditions across species' distribution promotes trait between populations different altitudes are inherited by following generation. Seeds from were exposed to temperature...
Several studies reported a negative relationship between altitude and seed mass. In cactus species, mass has been also related to seedling morphology (size shape). Here we studied Gymnocalycium monvillei (Lem.) Pfeiff. ex Britton & Rose, species with wide altitudinal distribution, the main aim of analyzing how affects size (height width) shape (globose or columnar). We collected seeds from five sites along entire distribution in Córdoba Mountains (sites were located 878 2230 m a.s.l.),...
Abstract The existence of a coordination between leaf and stem economic spectra in woody species has been postulated repeatedly the literature, with contrasting results. Here, we that this is conditioned by climate factors, being stronger stressful environments. To test hypothesis explored seasonally dry forest central Argentina at global scale, analysed if outcome their varies along climatic gradient. At local characterized 37 measuring six functional traits related to resource acquisition...
Livestock grazing represents an important human disturbance for vegetation worldwide. We analysed the intraspecific differences in mean trait values between different regimes (ungrazed and grazed) explored whether these are consistent across species a sub-humid mountain ecosystem Central Argentina. selected 14 of eight families, co-occurring both comprising herbaceous (grasses forbs) woody (shrubs trees) plants. For each regime we measured 12 traits related to plant size, carbon fixation...
Paraná, Yungas and Chaco Serrano ecoregions are among the most species-rich terrestrial habitats at higher latitude. However, information for tiger moths, one of speciose groups is unknown in these ecoregions. In this study, we assess their species richness composition all three Also investigated whether moths influenced by climatic factors altitude. Tiger moth were obtained with samples from 71 sites using standardized protocols (21 Yungas, 19 Paraná 31 Serrano). Rarefaction-extrapolation...
Abstract Question We address the following questions: (1) which are main plant communities in montane grasslands central Argentina; (2) do those differ terms of floristic composition, endemisms, chorotypes and life forms; (3) major environmental variables (climatic, topographic edaphic) associated with heterogeneity vegetation? Location Pampean Mountains (Sierras Pampeanas), Córdoba Province, Argentina, an area ca. 37,000 km 2 . Methods The survey was based on a data set comprising 746...
