Morphological and molecular variability of wild diploid and polyploid populations of Chrysolaena flexuosa (Sims) H. Rob: relevance for ornamental breeding
(Elsevier, 2020-01)Chrysolaena flexuosa is a South American species of ornamental interest, whose variability has not been explored. The objective of this work was to perform joint analyses of morphological and molecular traits in seven ... -
Morphological and physiological plasticity in seedlings of Araucaria angustifolia and Cabralea canjerana is related to plant establishment performance in the rainforest
(Elsevier, 2020)High phenotypic plasticity is an important characteristic that should have a tree species that is going to be used to restore degraded rainforests, as those are stressful and changing environments. Quantifying phenotypic ... -
Morphological and physiological traits reveal differential salinity tolerance of two contrasting Glandularia cultivars
(Springer, 2020-09)In view of the current, continuous decrease of water availability, the need to explore new mitigation alternatives has given focus to salt-tolerant genotypes. The aim of this work was to study salt tolerance of two ornamental ... -
The Morphological Basis of vicuña wool: Skin and gland structure in Vicugna vicugna (Molina 1782)
(2016-04)The vicuña (Vicugna vicugna) is the smallest member of the Camelidae with one of the most valuable fibers in the world. However, little is known of the structural basis for this fiber or of the skin glands used in chemical ... -
Morphological descriptions of the nymph and adults of Ornithodoros clarki, the larva and nymph of Ornithodoros rondoniensis, with notes on their phylogenetic relationships
(Springer, 2021-03-26)Based on tick specimens collected recently in Mexico, Nicaragua, Panama and Brazil, we provide morphological descriptions of the nymph and adults of Ornithodoros clarki Jones & Clifford, 1972 from the first three countries, ... -
Morphological diversity of populations of the genus Prosopis in the semiarid Chaco of northern Cordoba and southern Santiago Del Estero
(Scientific Research, 2013-11)The objective of this study consisted in the characterization of morphological variability presented in the Prosopis population in the corridor that unites the semiarid with the arid region in Argentina. In this region, ... -
Morphology and hydraulic architecture of Vitis vinífera L. cv. Syrah and Torrontes Riojano plants are unaffected by variations in red to far-red ratio
(2016)Plants have evolved an array of specific photoreceptors to acclimate to the light environment. By sensing light signals, photoreceptors modulate plant morphology, carbon- and water-physiology, crop yield and quality of ... -
Morphometric and Cytogenetic Studies in Mimosa diversipila (Mimosoideae, Leguminosae) and Their Taxonomic and Evolutionary Inferences
(American Society of Plant Taxonomists, 2014-07)Here we describe the morphological variability, chromosome number, and chromosome size in Mimosa diversipila. This species comprises two varieties, which are distinguished by the indumentum. However, this character is ... -
Morphometric and genetic characterization as tools for selection of Apis mellifera (Hymenoptera: Apidae) stocks in an area of natural hybridization in Argentina
(Frontiers Media, 2023-01)Beekeepers around the world select bees’ characteristics that facilitate and favor production. In regions where hybridization among lineages is taking place, this selection is a challenge, given that these regions are ... -
Morphometric study of encephalic lesions in aborted bovine fetuses naturally infected by two subpopulations of Neospora caninum
(Springer, 2021-08)Neospora caninum is a major reproductive disease in cattle worldwide. In the Argentinian Humid Pampa, the seroprevalence, incidence of abortions, and economic losses due to neosporosis are considerably higher in dairy than ... -
