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 ...
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 ...
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 ...
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 ...
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 ...
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 ...

Nacido el 24/03/1860 en Licata, provincia de Agrigento, Sicilia , Italia. Descendiente ...
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, ...
