Assessing spatial genetic structure from molecular marker data via principal component analyses: a case study in a Prosopis sp. fores
Teich, Ingrid; Verga, Anibal Ramón; Balzarini, Mónica Graciela (Scientific Research Publishing, 2014-01)Advances in genotyping technology, such as molecular markers, have noticeably improved our capacity to characterize genomes at multiple loci. Concomitantly, the methodological framework to analyze genetic data has expanded, ... -
Bosques monotípicos de Gonopterodendron sarmientoi: ambiente, genética y morfología de los palosantales
Camps, Gonzalo Andres; Sérsic, Alicia N.; Iglesias, M. del Rosario; Verga, Anibal; Cosacov, Andrea (Asociación Argentina de Ecología, 2022-06-26)Gonopterodendron sarmientoi —Palo Santo— es una especie forestal típica chaqueña, presente en bosques mixtos o formando densos bosques monotípicos (palosantales). Por pérdida de hábitat y alta explotación, G. sarmientoi ... -
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 ... -
Efecto de ácido naftalenacético, ácido indol-3-butírico y ácido indol-3-acético en la respuesta rizogénica in vitro de Neltuma alba = Effect of naphthaleneacetic acid, indole-3-butyric acid, and indole-3-acetic acid on the in vitro rhizogenic response of Neltuma alba
Carloni, Edgardo José; Rodriguez, Milena Nahir; Verga, Anibal; Grunberg, Karina (Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2024-08-30)Neltuma alba, conocido como “algarrobo blanco”, es una especie nativa importante en la ecorregión región del Chaco y especialmente en Argentina debido a su valor biológico, productivo y cultural. La sobreexplotación maderera ... -
Employing scientific evidence through synthetic indices to support management and conservation policies for an endangered tree of the Gran Chaco
Camps, Gonzalo Andres; Cosacov, Andrea; Verga, Anibal; Sérsic, Alicia N. (Elsevier, 2024-09)Management and conservation programs require accessible scientific evidence to effectively plan and achieve their goals. Facing regional and species-specific threats, Gonopterodendron sarmientoi, an endangered tree native ... -
Genetic and climatic approaches reveal effects of Pleistocene refugia and climatic stability in an old giant of the Neotropical Dry Forest
Camps, Gonzalo Andres; Martinez Meyer, Enrique; Verga, Anibal; Sérsic, Alicia; Cosacov, Andrea (Oxford University Press, 2018-07)Neotropical Dry Forests are important biodiversity hotspots characterized by intermediate to high levels of species richness and endemism. A possible explanation for these characteristics is that such forests have been ... -
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 ... -
In vitro micrografting as an innovative strategy for the vegetative propagation of algarrobo blanco (Neltuma alba)
Carloni, Edgardo José; Rodriguez, Milena Nahir; Verga, Anibal; Grunberg, Karina (Springer, 2025-05-28)Neltuma alba (Formerly Prosopis alba), known as ‘algarrobo blanco,’ is a native species of great biological, productive, and cultural importance in the phytogeographic regions of the Gran Chaco and the Espinal. However, ... -
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 ... -
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 ... -
Morphological diversity of populations of the genus Prosopis in the semiarid Chaco of northern Cordoba and southern Santiago Del Estero
Joseau, Marisa Jacqueline; Verga, Anibal; Díaz, María del Pilar; Julio, Norma Beatríz (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, ...
