Intra-specific variation in advertisement call of Odontophrynus cordobae (Anura, Cycloramphidae): A multilevel and multifactor analysis
(Brill Academic Publishers, 2013-01)
Advertisement call is a complex signal that can vary at different scales and the characterization of this variation is crucial to understand its adaptive function. In our study, we examined different factors that could ...

A framework for studying behavioral evolution by reconstructing ancestral repertoires
(eLife Sciences, 2021-09)
Although different animal species often exhibit extensive variation in many behaviors, typically scientists examine one or a small number of behaviors in any single study. Here, we propose a new framework to simultaneously ...
Seasonally persistent foraging niche segregation between sympatric Southern Rockhopper and Magellanic penguins breeding at Isla de los Estados, Argentina
(Springer, 2020-07)
Variation in the foraging strategies used among species is a key factor in determining the trophic structure of ecological communities. Moreover, foraging niche differentiation could be driven by inter-specific competition ...
Strontium isotope ratios of human hair record intra-city variations in tap water source
(Nature Publishing Group, 2018-12)
The oxygen (18O/16O) isotope analysis of hair is commonly applied to reconstruct an individual's residence history. However, region-of-origin as determined from oxygen isotope values (δ 18O) alone is often spatially ...
Call variability, stereotypy and relationships in syntopy of tetraploid common lesser escuerzo (Anura: Genus Odontophrynus)
(Elsevier Gmbh, 2017-05)
We studied patterns of the geographic variation of mating calls of the common lesser escuerzo Odontophrynus americanus including populations living in syntopy with the closely related O. cordobae and adjacent allopatric ...
Multi-band behaviour of the TeV blazar PG 1553+113 in optical range on diverse timescales. Flux and spectral variations
(EDP Sciences, 2020-11)
Context. The TeV BL Lac object PG1553+113 is one of the primary candidates for a binary supermassive black hole system.Aims. We study the flux and spectral variability of PG1553+113 on intra-night to long-term timescales ...

Intra-colonial viral infections in western honey bees (Apis mellifera)
(MDPI, 2021-05)
RNA viruses play a significant role in the current high losses of pollinators. Although many studies have focused on the epidemiology of western honey bee (Apis mellifera) viruses at the colony level, the dynamics of virus ...
