Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Comparative proteomic analysis reveals that juvenile hormone binding protein and adenylate kinase may be involved in the molting process of silkworm, Bombyx mori

Invertebrate Survival Journal, 2017
The molting is an essential part of the silkworm metamorphosis development. Although previous studies have demonstrated that molting in silkworm is associated with prothoracicotropic hormone (PTTH), molting hormone (MH), and juvenile hormone (JH), the ...

Environmentally induced stress affects fitness of bold and shy alike: A long‐term study of personality and feather corticosterone in Arctic‐breeding kittiwakes

Journal of Animal Ecology, EarlyView.
Quantifying how individuals differ as their environment changes around them is crucial to predict population responses to climate change. By incorporating personality, physiology and life‐history the authors show that while environmental change is likely to impact the whole population equally, when individuals are most impacted will vary across the ...

Bacteriological investigation of microorganisms (Salmonella sp. and other Enterobacteriaceae) in common quails (Coturnix coturnix) submitted to different forced-molting procedures

Brazilian Journal of Poultry Science, 2013
The aim of this study was to investigate the presence of Salmonella in common quails submitted to forced molting. A total of 240 quails were divided at 40 weeks of age into four groups: CG (control, quails not submitted to molting); FM (fasting method ...

Primary molt in Psophia and simpler molt summary tables

, 2018
Molt summary tables reveal the sequence and mode of flight feather replacement and how these feathers are divided into independent replacement series. These tables are relatively new, and the first illustration for generating molt summary tables used a temperate passerine.

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Spider mite genotypes with higher growth rate suffer more from competition but exert stronger reproductive interference

Journal of Animal Ecology, EarlyView.
Genetic correlations have strong implications for species coexistence and their evolution. Studies addressing this issue generally tackle traits associated with competition for food and those underlying reproductive interference separately, whereas it is clear that the interaction among these is key to understand the ecology and evolution of closely ...
