Análisis de estrategias de brotación de familias de polinización abierta de Prosopis alba Grisebach de Argentina
Frassoni, Javier Eduardo; Giannini Kurina, Franca; Lopez Lauenstein, Diego; Joseau, Marisa Jacqueline (Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2021-10-28)El objetivo del trabajo fue analizar las estrategias de brotación de familias de polinización abierta de Prosopis alba Grisebach en Argentina. Se seleccionaron 88 familias de interés en un ensayo de progenies ubicado en ... -
Design of seed transfer zones and assessment of germplasm collections of Neltuma alba for reforestation and afforestation purposes in Argentina
Orquera, Ricardo M.; Marinoni, Lorena del Rosario; Velazquez, Maria A.; Pensiero, José Francisco; Lopez Lauenstein, Diego; Vega, Carmen Delcira; Zabala, Juan Marcelo (Springer, 2024-11-25)The multipurpose tree Neltuma alba is widely distributed in forests of north-central Argentina but overexploitation and deforestation have led to forest transformation and endangered genetic diversity of this species. Thus, ... -
Drought stress tolerance of Prosopis chilensis and Prosopis flexuosa species and their hybrids
Lopez Lauenstein, Diego; Fernandez, María Elena; Verga, Anibal (Springer, 2013-02)Natural hybridization commonly produces individuals with intermediate morphological and genetic characteristics, but their response to environmental stress is still uncertain, with some studies showing that transgressive ... -
Heritable leaf traits as indicators of drought tolerance in Neltuma Alba for genetic improvement and ecological restoration
Lopez Lauenstein, Diego; Vega, Carmen Delcira; Verga, Anibal; Lascano, Hernan Ramiro; Marchelli, Paula (Springer, 2026)Climate change-induced droughts are pressing threats to forest species, especially in semi-arid regions like the Chaco, in South America. Developing drought-adapted genetic material for Neltuma alba, a keystone species for ... -
Local adaptative strategies for coping with drought stress in Neltuma alba (Leguminosae, Caesalpinioideae) are associated with the timing of leaf senescence
Lopez Lauenstein, Diego; Vega, Carmen Delcira; Verga, Anibal; Lascano, Hernan Ramiro; Marchelli, Paula (Springer, 2025-03-26)Drought stress is a significant abiotic factor that limits plant growth and has led to widespread tree mortality worldwide. As climate change predicts longer, more severe, and unpredictable drought periods in subtropical ... -
Mind the Gaps: Shortfalls in Studies of the Intraspecific Genetic Diversity of Plants Across the Gran Chaco
González, María Laura; Camps, Gonzalo Andres; Sérsic, Alicia Noemí; Cosacov, Andrea; Acosta, Maria Cristina; Aguilar, Dana Lucía; Almirón, Noelia E.A.; Chiapero, Ana Laura; Lopez Lauenstein, Diego; Scaldaferro, Marisel Analía; Sosa-Pivatto, Maria; Via do Pico, Gisela; Moreno, Ercilia M.S.; Vega, Carmen Delcira; Solis Neffa, Viviana; Baranzelli, Matias Cristian (Wiley, 2025-12)Intraspecific genetic diversity (IGD) is a fundamental component of biodiversity, essential for understanding the evolutionary histories and demographic processes of species, and is key to effective conservation planning. ... -
Morphological and molecular characterization of a hybrid zone between Prosopis alba and P. nigra in the Chaco region of northwestern Argentina
Vega, Carmen Delcira; Teich, Ingrid; Acosta, Maria Cristina; Lopez Lauenstein, Diego; Verga, Anibal; Cosacov, Andrea (JD Sauerlaender's Verlag, 2020-06-26)The Gran Chaco is the largest dry forest in South America. One of the key taxa of this biome is the genus Prosopis (Fabaceae) which contains several economically important species. One of the characteristics of this genus ... -
Neutral and adaptive genetic diversity in Neltuma alba (Leguminosae), an emblematic species of the Dry Chaco Forest
González, María Laura; Cosacov, Andrea; Lopez Lauenstein, Diego; Vega, Carmen Delcira; Teich, Ingrid; Bessega, Cecilia (Oxford University Press, 2025-08-11)Dry forests, characterized by seasonal rainfall, are exposed to prolonged drought periods and high temperatures throughout the year, with the consequent restricted water availability. Organisms occurring in these environments ... -
Nurse plants and seed provenance in the restoration of dry Chaco forests of central Argentina
Venier, P.; Ferreras, A.E.; Lopez Lauenstein, Diego; Funes, G. (Elsevier, 2023-02-01)In degraded dry environments, a promising restoration strategy involves nurse plants and their microsites, which facilitate species recruitment. Different nurse plant species might provide different microclimatic and soil ... -
Provenance matters: variability under saline stress in young plants of four populations of a Prosopis (mesquite) species from dry forests of Argentina
Vennier, María Paula; Funes, G.; Teich, Ingrid; Lopez Lauenstein, Diego; Lascano, Hernan Ramiro (Canadian Science Publishing, 2021-01-04)The planting of native perennial woody species tolerant to variable salt concentrations can facilitate the recovery of degraded dry forests. The objective of this study was to evaluate and compare, under experimentally ...
