Aggressive dominance can decrease behavioral complexity on subordinates through synchronization of locomotor activities
(2019-12-12)Social environments are known to influence behavior. Moreover, within small social groups, dominant/subordinate relationships frequently emerge. Dominants can display aggressive behaviors towards subordinates and sustain ... -
Cambios florísticos inducidos por la frecuencia de fuego en el Chaco serrano.
(Boletín de la Sociedad Argentina de Botánica, 2017)Las Sierras Chicas de Córdoba son el cordón montañoso con mayor frecuencia de fuego del centro de Argentina. Sin embargo, hasta el momento no se ha evaluado cuál es la respuesta de las comunidades de plantas del Chaco ... -
Carbonate collapse and the late Paleozoic ice age marine biodiversity crisis
(2020)The late Paleozoic ice age (LPIA) was characterized by persistently low diversity of marine invertebrates following a second-order mass extinction. Here, we used a data set of North American (paleotropical) fossil ... -
Contrasting effects of fire frequency on plant traits of three dominant perennial herbs from Chaco Serrano.
(Wiley Blackwell Publishing, Inc, 2016)Fire frequencies are currently increasing in many regions a cross the world as a result of anthropic activities, affecting ecological processes and plant population dynamics. Fire can generate important changes in soil ... -
Expression of aggressiveness modulates mesencephalic c-fos activation during a social interaction test in Japanese quail (Coturnix japonica)
(2019-07-23)It is well known that during a social conflict, interactions are dependent on the animal's propensity to behave aggressively as well as the behavior of the opponent. However, discriminating between these two confounding ... -
Fire frequency effects on soil and pollinators: what shapes sexual plant reproduction?
(Springer, 2017-12)Increased fire frequency can significantly erode both soil properties and plant–pollinator interactions affecting plant reproductive success but they have seldom been assessed simultaneously. Here, we evaluate soil properties, ... -
High-resolution ethograms, accelerometer recordings, and behavioral time series of Japanese quail
(2024-01-02)Although many small vertebrates are capable of performing high-speed behaviors, most studies continue to focus on low-resolution temporal scales (>>1 s). Herein, we present video-recordings, behavior time series, and the ... -
Mitochondrial chaotic dynamics: Redox-energetic behavior at the edge of stability
(2018-10-18)Mitochondria serve multiple key cellular functions, including energy generation, redox balance, and regulation of apoptotic cell death, thus making a major impact on healthy and diseased states. Increasingly recognized is ... -
Movilidad residencial de sectores medios y populares: la ciudad de Buenos Aires como punto de llegada
(2018-04)El artículo reflexiona acerca de los patrones de movilidad residencial de individuos y hogares de sectores populares y medios que residen en dos zonas de la Ciudad de Buenos Aires configuradas en torno a patrones disimiles ... -
Obituario del Señor Angel Peritore

El rol del herbario ACOR en la comunidad: colección, ciencia y educación.
(Facultad de Ciencias Agropecuarias, 2015)Las colecciones representan un testigo imprescindible para la ciencia y un vehículo para arribar a posibles y adecuadas soluciones a los problemas de la comunidad. Los herbarios son el único documento de la vegetación sobre ... -
The relevance of a right scale for sampling when studying high-resolution behavioral dynamics
(2023)Many species used in behavioral studies are small vertebrates with high metabolic rates and potentially enhanced temporal resolution of perception. Nevertheless, the selection of an appropriate scales to evaluate behavioral ... -
The search for Pleiades in trait constellations: functional integration and phenotypic selection in the complex flowers of Morrenia brachystephana (Apocynaceae)
(2014-03-18)Pollinator‐mediated natural selection on single traits, such as corolla tube or spur length, has been well documented. However, flower phenotypes are usually complex, and selection is expected to act on several traits that ... -
Travelling to the south: Phylogeographic spatial diffusion model in Monttea aphylla (Plantaginaceae), an endemic plant of the Monte Desert
(2017-05)Effects of Pleistocene climatic oscillations on plant phylogeographic patterns are relatively well studied in forest, savanna and grassland biomes, but such impacts remain less explored on desert regions of the world, ... -
Unprecedented plant species loss after a decade in fragmented subtropical Chaco Serrano forests.
(Anne Mireille Regine Duplouy, Lund University., 2018-11-28)Current biodiversity loss is mostly caused by anthropogenic habitat loss and fragmentation, climate change, and resource exploitation. Measuring the balance of species loss and gain in remaining fragmented landscapes ...
