Living on an island: characterization of the encrusting fauna of large pectinid bivalves from the Lower Cretaceous of the Neuquén Basin, west-central Argentina
(Wiley, 2015-09)
Exposed mollusc shells may act as benthic islands in soft bottoms, and the analysis of their encrusting faunas provides unique palaeoecological information. In the late Valanginian of the Agrio Formation (Neuquén Basin, ...
Microsatellite evidence for sperm storage and multiple paternity in the marine gastropod Crepidula coquimbensis
(ELSEVIER SCIENCE BV, 2011)
In gregarious species with copulation and internal fertilization, male-male competition and female cryptic choice may affect reproductive success of both sexes. We carried out a molecular analysis to study paternity and ...
Gregarious versus individualistic behavior in Vicsek swarms and the onset of first-order phase transitions
(Elsevier Science, 2013-04)
The standard Vicsek model (SVM) is a minimal non-equilibrium model of self-propelled particles that appears to capture the essential ingredients of critical flocking phenomena. In the SVM, particles tend to align with each ...
A mechanism for pattern formation in dynamic populations by the effect of gregarious instinct
(Elsevier Science, 2012-01-01)
We introduced the gregarious instinct by means of a novel strategy that considers the average effect of the attractive forces between individuals within a given population. We watched how pattern formation can be explained ...
