Lethal Agonistic Behavior between Two Male Magellanic Woodpeckers Campephilus magellanicus Observed in the Cape Horn Area
(Wilson Ornithological Soc, 2016)
Agonistic behavior in woodpeckers has been described for a wide range of species, although previous studies have not reported aggressive encounters resulting in the death of adults. In this study, we provide the first ...
Chemical communication, aggression, and conspecific recognition in the fish Nile tilapia
(Elsevier B.V., 1997-12-01)
The chemical modulation of agonistic behavior and conspecific recognition were tested in juveniles of the fish Nile tilapia, Oreochromis niloticus (L.). After a 7-day isolation period, the fish were grouped (four individuals ...

Long-term social recognition memory in adult male rats: factor analysis of the social and non-social behaviors
(Associação Brasileira de Divulgação Científica, 2010)
A modified version of the intruder-resident paradigm was used to investigate if social recognition memory lasts at least 24 h. One hundred and forty-six adult male Wistar rats were used. Independent groups of rats were ...
Sexual Differences in the Behavior of the Harvestman Leiobunum vittatum (Opiliones, Sclerosomatidae) Towards Conspecific Cues
(SPRINGER/PLENUM PUBLISHERSNEW YORK, 2012)
Preliminary observations of the harvestman Leiobunum vittatum found that individuals rub their bodies against the substrate, presenting the possibility of chemical marking. To determine whether or not L. vittatum individuals ...
Adrenocortical responses in Japanese quail classified by their permanence in proximity to either low or high density of conspecifics
(Poultry Science Association, 2018-06-19)
The density-related permanence test (DRP) is used to classify young birds (while in groups) according to their individual permanence in proximity to either a high or low density of conspecifics (HD or LD, respectively). ...
Social interaction of juvenile Japanese quail classified by their permanence in proximity to a high or low density of conspecifics
(Poultry Science Association, 2013-10)
One challenge faced by ethologists in poultry welfare is helping birds to form functionally successful groups over time through the expression of appropriate behaviors. Searching for phenotypic variability, we developed ...
