Nonequilibrium evolution of volatility in origination and extinction explains fat-tailed fluctuations in Phanerozoic biodiversity
(Science Advances is the American Association for the Advancement of Science, 2019-06)
Fluctuations in biodiversity, large and small, pervade the fossil record, yet we do not understand the processes generating them. Here, we extend theory from nonequilibrium statistical physics to describe the fat-tailed ...
Adaptive modification of tail structure in relation to body mass and buckling in woodcreepers
(Cooper Ornithological Society, 2002-05)
We assessed the relationship between function and tail structure of woodcreepers (Dendrocolaptidae) and Neotropical ovenbirds (Furnariidae) using a comparative analysis of independent contrasts. Because woodcreepers are ...

Wing and tail myology of Tyto furcata (Aves, Tytonidae)
(Veterinary and Human Toxicology, 2020-04)
Barn Owls (Tytonidae) are nocturnal raptors with the largest geographical distribution among Strigiformes. Several osteological, morphometrical, and biomechanical studies of this species were performed by previous authors. ...
Epoxy Networks with Physical Cross-Links Produced by Tail-to-Tail Associations of Alkyl Chains
(American Chemical Society, 2009-10)
In a recent paper (Zucchi, I. A.; et al. Macromolecules 2008, 41, 4895), we showed that linear amphiphilic epoxy polymers synthesized by the polyaddition of diglycidyl ether of bisphenol A (DGEBA) with dodecylamine (DA) ...
Outliers, structural shifts and heavy-tailed distributions in state space time series models
(Pakistan Journal of Statistics, 2002-12)
In this work a general method is developed for handling outliers, structural shifts and heavy-tailed distributions in linear state space time series models. The basic tool we use for dealing with outliers and structural ...
Communal roosting behavior and winter diet of the white-tailed kite (Elanus leucurus) in an agricultural habitat on the Argentine pampas
(Bio one, 2010-09)
Although the White-tailed Kite (Elanus leucurus) is widely distributed throughout the Americas, winter communal roosting has been recorded only in the Nearctic portion of its range. As a result, data on the food habits of ...

(Neotropical Bird Club, 2020-07)
El Atajacaminos Lira Uropsalis lyra es un caprimúlgido andino poco conocido. En Argentina se desconocen aspectos básicos de su biología reproductiva. Presentamos notas sobre su reproducción en base a cuatro nidos ubicados ...
Tidal tails of Milky Way globular clusters
(EDP Sciences, 2020-05)
We report on the search for overall kinematical or structural conditions that have allowed some Milky Way globular clusters to develop tidal tails. For this purpose, we built a comprehensive catalog of globular clusters ...
