Determinants of moult haulout phenology and duration in southern elephant seals

open access: yesScientific Reports, 2021
Phenological shifts are among the most obvious biological responses to environmental change, yet documented responses for Southern Ocean marine mammals are extremely rare.

Birds of three worlds: moult migration to high Arctic expands a boreal-temperate flyway to a third biome

open access: yesMovement Ecology, 2021
Background Knowledge on migration patterns and flyways is a key for understanding the dynamics of migratory populations and evolution of migratory behaviour. Bird migration is usually considered to be movements between breeding and wintering areas, while

Nutrient Composition and Growth of Yellow Mealworm (Tenebrio molitor) at Different Ages and Stages of the Life Cycle

open access: yesAgriculture, 2022
The nutrient composition of yellow mealworm (YM) Tenebrio molitor varies based on the stages of the life cycle, the rearing conditions, and the feeding substrate.

Sequence of post-moult exoskeleton hardening preserved in a trilobite mass moult assemblage from the Lower Ordovician Fezouata Konservat-Lagerstätte, Morocco [PDF]

open access: yesActa Palaeontologica Polonica, 2019
Euarthropods have a tough exoskeleton that provides crucial protection from predation and parasitism. However, this is restrictive to growth and must be periodically moulted.

moult: AnRPackage to Analyze Moult in Birds [PDF]

open access: yesJournal of Statistical Software, 2013
Moult is the process by which birds replace their feathers. It is a costly process in terms of energy and reduced flight ability but necessary for the maintenance of the plumage and its functions. Because birds generally avoid to moult while engaged with other energy demanding activities such as breeding and migration, the analysis of moult data gives ...

Premigratory moult in the Lesser Kestrel Falco naumanni

open access: yesAvocetta, 2019
Moult is one of three major energy-demanding life-history events in the annual cycle of birds but unlike breeding and migration it is poorly studied. Most of the long-distance migratory raptors suspend moult during migration and then finish it in their ...

Differences in tail feather growth rate in storm-petrels breeding in the Northern and Southern hemisphere: a ptilochronological approach [PDF]

open access: yesPeerJ, 2019
Moulting and breeding are costly stages in the avian annual cycle and may impose trade-offs in energy allocation between both stages or in their timing.

Migration strategies, performance and annual activity budget in a short‐distance migrant, the common starling Sturnus vulgaris

open access: yesJournal of Avian Biology, 2023
Migratory birds typically separate energetically demanding parts of the annual cycle like breeding, moult and migration with some species engaging in so‐called moult‐migration.

Temporal and spatial differences in the post-breeding behaviour of a ubiquitous Southern Hemisphere seabird, the common diving petrel [PDF]

open access: yesRoyal Society Open Science, 2020
The non-breeding period plays a major role in seabird survival and population dynamics. However, our understanding of the migratory behaviour, moulting and feeding strategies of non-breeding seabirds is still very limited, especially for small-sized ...
