Arbuscular mycorrhizal fungi (AMF) colonize land plants in every ecosystem, even extreme conditions such as saline soils. In the present work we report for first time status and vertical fungal distribution of AMF spores rhizospheric soil samples four species Chenopodiaceae (Allenrolfea patagonica, Atriplex argentina, Heterostachys ritteriana Suaeda divaricata) at five different depths two central Argentina. Roots showed medium, low or no colonization (0-50%). Nineteen morphologically...
The biogeographic region of Argentinean Puna mainly extends at elevations higher than 3,000 m within the Andean Plateau and hosts diverse ecological communities highly adapted to extreme aridity low temperatures. Soils are typically poorly evolved geomorphology is shaped by drainage networks, resulting in vegetated endorheic basins hypersaline known as salar or salt flats. Local rely on soil fertility for agricultural practices pastures livestock rearing. From this perspective, investigating...
Summary Biotic and abiotic context may affect the intensity of interspecific interactions subsequently drive locally particular phenotypic selection patterns on interacting traits. We evaluated geographical variation matching traits brush‐type flowers Caesalpinia gilliesii proboscis length its guild hawkmoth pollinators, as well their relationship with environmental variables. assessed (style filament vs mean hawkmoths) across seven populations estimated plant side. Interacting showed...
The adaptive accuracy of flowers in the context pollination can be used to address relationships between flower phenotype (fundamental and precision) realized precision (interaction floral parts with a pollinator). Here we tested whether effectiveness (number pollen grains transported per visit) male female differ two hummingbird pollinator species (Heliomaster furcifer Sappho sparganura) that pollinate ornithophilous liana Dolichandra cynanchoides. Although did not frequency visitation, H....
The coevolutionary process among free-living mutualists with extremely long matching traits may favor the formation of mutualistic interaction networks through escalation, complementarity and convergence. These be geographically structured; links species a local network are shaped by biotic composition community, thus creating selection mosaics at broader geographical scales. Therefore, to fully understand process, it is crucial visualize structure across landscape. In this study we focused...
Floral scent is a key communication channel between plants and pollinators. However, the contributions of environment phylogeny to floral composition remain poorly understood. In this study, we characterized interspecific variation in genus Jaborosa Juss. (Solanaceae) and, using an ecological niche modelling approach (ENM), assessed environmental variables that exerted strongest influence on variation, taking into account pollination mode phylogenetic relationships. Our results indicate two...

Summary: Arbuscular fungi (Glomeromycota) in the rhizosphere of Atriplex lampa at two saline environments Córdoba (Argentina): depth influence on root colonization and presence morphospecies. is a valuable fodder shrub available for browsing by livestock even during drought periods Chaco Phytogeographical Province. Halophytes may benefit from association with arbuscular mycorrhizal (AMF) through improved tolerance to salt. Ecological studies AMF are generally restricted main rooting zone....
Climate and resource availability at the parent tree location are known to explain progeny characteristics; however, few studies have examined role of resistance or tolerance pathogens, even though climate is a main driver pathogen abundance. We hypothesize that has relatively greater influence on pathogens than other characteristics, such as seed mass seedling growth. As study species we used vulnerable Neotropical Kageneckia lanceolata be susceptible damping-off diseases. collected seeds...
ABSTRACT Knowledge about tree production practices is essential to support forest restoration projects, but still lacking for many species. Maytenus boaria a neotropical distributed across the temperate and subtropical South American mountains. In central Argentina, it mainly restricted most preserved remnants. Attempts plant this species have had little success due difficulties in seedling low survival. We set up four trials aiming identify constraints of outplanting. Under greenhouse...
