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 ... -
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 ... -
Efecto de los visitantes nativos y exóticos sobre la germinación de Lepechinia floribunda (Lamiaceae)
(Universidad San Francisco Xavier de Chuquisaca, 2024-04-26)La relación entre las plantas con flores y los polinizadores rara vez ocurre de a pares dado que la mayoría de las especies de plantas son visitadas por más de una especie polinizadora. Un aspecto central es la identificación ... -
Enhancing structural diversity through chemical engineering of Ambrosia tenuifolia extract for novel anti-glioblastoma compounds
(2024-06-20)Natural products are an unsurpassed source of leading structures in drug discovery. The biosynthetic machinery of the producing organism offers an important source for modifying complex natural products, leading to analogs ... -
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, ... -
Flying to greener pastures: Spider ballooning in the city
(Cotter, Sheena, Murphy, Shannon, Wilson, Robert, Fox, Charles, 2024-01-12)Abstract: Spider ballooning is a phenomenon in which spiders employ silk threads to travel through the air for dispersal. While this behaviour has been extensively studied in agricultural areas, limited research has been ... -
Linking South American dry regions by the Gran Chaco:Insights from the evolutionary history and ecologicaldiversification of Gomphrena s.str. (Gomphrenoideae, Amaranthaceae)
(2024-07)Abstract: Geoclimatic events driving South American aridization have generated biota differentiation due to barriers and new environment formation. New environments allow species climatic niche evolution, or the geographical ... -

(2024-07-02)Conocer la distribución de los animales es esencial para entender su ecología y comportamiento y la participación de las comunidades locales en esta tarea resulta clave. Aquí presentamos cuatro nuevos registros de Tamandua ... -
Nutrient and bioactive compounds from Neltuma spp. seeds
(2024-01)Abstract: In the search for compounds with nutritional and functional value, seeds from several Neltuma species were examined for lipid, protein and phenolic compo- nents. Lipid contents ranged between 9.3 and 12.5 g/100 ... -
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 ...
