Moult-Induced Changes in Gut Microbiota of African Penguins (Spheniscus demersus) [PDF]
AnimalsThe gut microbiota of seabirds can undergo shifts during the moulting period due to fasting. Understanding the characteristics of gut microbiota in African penguins (Spheniscus demersus) throughout moulting is meaningful for the conservation and ...

Divergent primary moult-A rare moult sequence among Western Palaearctic passerines.
PLoS ONE, 2017 Wing morphology strongly affects flight performance which may consequently decline during feather moult due to the creation of feather gaps in the wing. Hence, the size and shape of moult-related wing gap may directly affect flight capacity.

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Veterinary Medicine, 2022 The paper aimed to present the evolution of food intake, body weight, laying performance, mortality, ovary and oviduct weight and protein metabolism in 63-week-old natural moulted Hy-Line var. Brown hens housed in industrial system.

Differences in phenology across three trophic levels between two Afrotropical sites separated by four degrees latitude [PDF]
Ecology and EvolutionBirds time their life cycle events to favourable windows in environmental conditions. In tropical environments, where photoperiod variation is small, birds show high variability in the timing of life cycle stages, yet these species have been severely ...

Diet of moulting Swainson's Thrushes (Catharus ustulatus) and Tennessee Warblers (Leiothlypis peregrina) at a stopover site during fall migration measured with fecal DNA metabarcoding [PDF]
Scientific ReportsMoult and migration are energetically demanding and require adequate nutrition. In some species, individuals may interrupt their fall migration to moult at discrete stopover locations outside of their breeding grounds (i.e., moult-migration) leading to ...

Avian Research, 2023 Sequence and intensity are two essential components of bird moult. While the moult sequences of remex tracts are highly homogenous across passerines, other tracts apparently show a high variability.

Journal of High Energy Physics, 2012 Abstract We find a family of novel supersymmetric phases of the D1-D5 CFT, which in certain ranges of charges have more entropy than all known ensembles. We also find bulk BPS configurations that exist in the same range of parameters as these phases, and have more entropy than a BMPV black hole; they can be thought of as coming ...

Moult Strategies Affect Age Differences in Autumn Migration Timing in East Mediterranean Migratory Passerines. [PDF]
PLoS ONE, 2016 Adult passerines renew their flight feathers at least once every year. This complete moult occurs either in the breeding areas, just after breeding (summer moult), or, in some long-distance migratory species, at the non-breeding areas, after arrival to ...

When moult overlaps migration: moult-related changes in plasma biochemistry of migrating common snipe [PDF]
PeerJ, 2017 Moult of feathers entails considerable physiological and energetic costs to an avian organism. Even under favourable feeding conditions, endogenous body stores and energy reserves of moulting birds are usually severely depleted.

Ecological Indicators, 2021 Global warming affects ecosystem services, communities and populations, influencing the physiology, behaviour or environment of living beings, and hence impacts its survival or breeding.
