Cím:Experimental increase in baseline corticosterone level reduces oxidative damage and enhances innate immune response / Csongor I. Vágási, Laura Pătraș, Péter L. Pap, Orsolya Vincze, Cosmin Mureșan, József Németh, Ádám Z. Lendvai

Megjegyzések:Glucocorticoid (GC) hormones are significant regulators of homeostasis. The physiological effects of GCs critically depend on the time of exposure (short vs. long) as well as on their circulating levels (baseline vs. stress-induced). Previous experiments, in which chronic and high elevation of GC levels was induced, indicate that GCs impair both the activity of the immune system and the oxidative balance. Nonetheless, our knowledge on how mildly elevated GC levels, a situation much more common in nature, might influence homeostasis is limited. Therefore, we studied whether an increase in GC level within the baseline range suppresses or enhances condition (body mass, hematocrit and coccidian infestation) and physiological state (humoral innate immune system activity and oxidative balance). We implanted captive house sparrows Passer domesticus with either 60 days release corticosterone (CORT) or control pellets. CORT-treated birds had elevated baseline CORT levels one week after the implantation, but following this CORT returned to its pre-treatment level and the experimental groups had similar CORT levels one and two months following the implantation. The mass of tail feathers grown during the initial phase of treatment was smaller in treated than in control birds. CORT implantation had a transient negative effect on body mass and hematocrit, but both of these traits resumed the pre-treatment values by one month post-treatment. CORT treatment lowered oxidative damage to lipids (malondialdehyde) and enhanced constitutive innate immunity at one week and one month post-implantation. Our findings suggest that a relatively short-term (i.e. few days) elevation of baseline CORT might have a positive and stimulatory effect on animal physiology.

Cím:Haste makes waste but condition matters : Molt rate-feather quality trade-off in a sedentary songbird / Csongor I. Vágási, Péter L. Pap, Orsolya Vincze, Zoltán Benkő, Attila Marton, Zoltán Barta
Dátum:2012
ISSN:1932-6203
Megjegyzések:AbstractBackground: The trade-off between current and residual reproductive values is central to life history theory, although thepossible mechanisms underlying this trade-off are largely unknown. The ♭molt constraint' hypothesis suggests that molt andplumage functionality are compromised by the preceding breeding event, yet this candidate mechanism remainsinsufficiently explored.Methodology/Principal Findings: The seasonal change in photoperiod was manipulated to accelerate the molt rate. Thistreatment simulates the case of naturally late-breeding birds. House sparrows Passer domesticus experiencing acceleratedmolt developed shorter flight feathers with more fault bars and body feathers with supposedly lower insulation capacity (i.e.shorter, smaller, with a higher barbule density and fewer plumulaceous barbs). However, the wing, tail and primary featherlengths were shorter in fast-molting birds if they had an inferior body condition, which has been largely overlooked inprevious studies. The rachis width of flight feathers was not affected by the treatment, but it was still condition-dependent.Conclusions/Significance: This study shows that sedentary birds might face evolutionary costs because of the molt rate?feather quality conflict. This is the first study to experimentally demonstrate that (1) molt rate affects several aspects of bodyfeathers as well as flight feathers and (2) the costly effects of rapid molt are condition-specific. We conclude that molt rateand its association with feather quality might be a major mediator of life history trade-offs. Our findings also suggest a noveladvantage of early breeding, i.e. the facilitation of slower molt and the condition-dependent regulation of feather growth.

Cím:Local environment but not genetic differentiation influences biparental care in ten plover populations / Orsolya Vincze, Tamás Székely, Clemens Küpper, Monif AlRashidi, Juan A.

Megjegyzések:Social behaviours are highly variable between species, populations and individuals. However, it is contentious whether behavioural variations are primarily moulded by the environment, caused by genetic differences, or a combination of both. Here we establish that biparental care, a complex social behaviour that involves rearing of young by both parents, differs between closely related populations, and then test two potential sources of variation in parental behaviour between populations: ambient environment and genetic differentiation. We use 2904 hours behavioural data from 10 geographically distinct Kentish (Charadrius alexandrinus) and snowy plover (C. nivosus) populations in America, Europe, the Middle East and North Africa to test these two sources of behavioural variation. We show that local ambient temperature has a significant influence on parental care: with extreme heat (above 40?C) total incubation (i.e. % of time the male or female incubated the nest) increased, and female share (% female share of incubation) decreased. By contrast, neither genetic differences between populations, nor geographic distances predicted total incubation or female's share of incubation. These results suggest that the local environment has a stronger influence on a social behaviour than genetic differentiation, at least between populations of closely related species.
