Cím:Androgens Increase Persistence But Do Not Affect Neophobia in a Problem-Solving Context in a Songbird / Zoltán Németh, Ryan H. Adams, Marilyn Ramenofsky
Dátum:2015
ISSN:0179-1613 1439-0310
Megjegyzések:Gonadal steroid hormones enhance cognitive performance, particularly spatial and vocal learning, in mammals and birds. However, it is unknown whether problem-solving ability is similarly regulated. We propose that androgens, such as testosterone and 5α-dihydrotestosterone, play a role in mediating problem-solving behavior as well. As a test, male white-crowned sparrows (Zonotrichia leucophrys gambelii) were either castrated and administered a blank (Blank-castrate) or testosterone-filled implant (T-castrate) or were sham operated and were exposed to a novel feeder, which they had to open to receive a food reward, in two trials. Testosterone treatment affected neither a neophobic response nor problem?solving performance. However, T-castrates were more persistent in manipulating the feeder than Blank-castrates or Shams. Furthermore, their persistence correlated positively with circulating levels of both testosterone and 5α-dihydrotestosterone. We suggest that a positive correlation between sex steroids and persistence in foraging and problem?solving contexts may lead to an adaptive increase in resource acquisition in the breeding season. Given the overall low success on the problem?solving test, we cannot confidently conclude that androgens do not play a role in mediating problem-solving behavior. However, unlike in mammals, it seems these hormones do not significantly influence neophobia in foraging contexts in birds.

Cím:Colony size, nestmate density and social history shape behavioural variation in Formica fusca colonies / Anna Ágnes Somogyi, András Tartally, István Elek Maák, Zoltán Barta
Dátum:2020
ISSN:0179-1613 1439-0310
Megjegyzések: In ants, individuals live in tightly integrated units (colonies) and work collectively for its success. In such groups, stable intraspecific variation in behaviour within or across contexts (personality) can occur at two levels: individuals and colonies. This paper examines how colony size and nestmate density influence the collective exploratory behaviour of Formica fusca (Hymenoptera: Formicidae), in the laboratory. The housing conditions of the colonies were manipulated to vary the size of colonies and their densities under a fully factorial design. The results demonstrate the presence of colony behavioural repeatability in this species, and contrary to our expectations, colonies were more explorative on average when they were kept at lower nestmate densities. We also found that experimental colonies created from larger source colonies were more explorative, which conveys that a thorough understanding of the contemporary behaviour of a colony may require knowing its social history and how it was formed. Our results also convey that the colony size and nestmate density can have significant effects on the exploratory behaviour of ant colonies.
