Autor: Karen Bauk, Federico Santiñaque, Beatriz López-Carro, M. L. Las Peñas

Publikováno v: Boletín de la Sociedad Argentina de Botánica, Vol 51, Iss 2 (2016)

Stetsonia coryne es una planta de porte arborescente y con flores grandes (12 a 15 cm de largo) e infundibuliformes. Es originaria de los desiertos del noroeste de Argentina y Bolivia, y es la única especie del género Stetsonia. El objetivo de este

Genetic variables, population features and reproductive success ofGymnocalycium monvillei(Cactaceae) along an altitudinal gradient

Autor: Karen Bauk, Diego E Gurvich, Zlatko Liber, Zlatko Šatović, M Laura Las Peñas

Publikováno v: Botanical Journal of the Linnean Society.

Altitudinal gradients in mountain environments impose selection pressures that could result in marked heterogeneity in genetic characteristics, population features and reproductive success. Most Cactaceae occur in arid and semi-arid areas of the Amer

Publikováno v: Journal of Arid Environments. 185:104382

Understanding the effects of long-term seed storage on germination is important to elucidate both soil seed bank dynamics and capacity of seeds to be preserved in ex situ conservation programs. We collected seeds 13 cactus species from central Argent

Ecological significance of determinate primary root growth: inter- and intra-specific differences in two species of Gymnocalycium (Cactaceae) along elevation gradients

Autor: Karen Bauk, María Cecilia Ferrero, Diego E. Gurvich, M. L. Las Peñas, P.A. Martino

Determinate primary root growth in Cactaceae has been interpreted as an adaptation to dry environments. However, little information is available regarding ecological patterns of this process. Our research question was whether primary root length is a

Are seed mass and seedling size and shape related to altitude? Evidence in Gymnocalycium monvillei (Cactaceae)

Autor: Joel Flores, M. Laura Las Peñas, Reyes Pérez-Sánchez, Sebastián R. Zeballos, Karen Bauk, Diego E. Gurvich

Publikováno v: Botany. 93:529-533

Several studies reported a negative relationship between altitude and seed mass. In cactus species, seed mass has been also related to seedling morphology (size and shape). Here we studied Gymnocalycium monvillei (Lem.) Pfeiff. ex Britton & Rose, a c

Germination characteristics of Gymnocalycium monvillei (Cactaceae) along its entire altitudinal range

Autor: Joel Flores, Diego E. Gurvich, M. Laura Las Peñas, Cecilia Ferrero, Karen Bauk, Reyes Pérez-Sánchez

Germination characteristics are important for understanding how species cope with environmental variation. The aims of this work were to analyze the effect of different temperatures (25 and 32 °C), water potentials (0, -0.2, -0.4, and -0.6 MPa), and

Combined effect of water potential and temperature on seed germination and seedling development of cacti from a mesic Argentine ecosystem

Autor: Guillermo Funes, Reyes Pérez-Sánchez, Joel Flores, María Cecilia Ferrero, Diego E. Gurvich, Karen Bauk, Enrique Jurado

Global climatic change will be associated with an increase of droughts and heat waves, which can affect seed germination and plant population dynamics. Cactus species from mesic ecosystems are likely to be more affected by these events than species f
