Moult performance varies in relation to colour patterns in crossbills
Carotenoid-based ornamentation can vary greatly among individual birds of the same population. This variability might consider the timing and...

Independent evolution of intermediate bill widths in a seabird clade
Interspecific introgression can occur between species that evolve rapidly within an adaptive radiation. Pachyptila petrels differ in bill size and...

Male nuptial display colour and vocalisation appear to signal independent information in the whirring tree frog
AbstractWhen different modes of communication are used in combination and for example convey visual and acoustic information, they form a multimodal...

Ectoparasites exposure affects early growth and mouth colour in nestlings of a cavity-nesting raptor
AbstractNest-dwelling ectoparasites are a major source of stress for growing nestling birds, as they can negatively impact on growth and physiology,...

Behavioural and physiological responses to experimental temperature changes in a long-billed and long-legged bird: a role for relative appendage size?
AbstractMaintaining homeothermy may be a major challenge when species are confronted with ambient temperatures beyond their thermoneutral zone. Bird...

Size-assortative mating in a long-lived monogamous seabird
Mate choice is a key process in animals to optimize the fitness benefits of reproduction, and it is generally guided by phenotypic features of...

Plumage and bill abnormalities in albatross chicks on Marion Island
Accessible colonies of Grey-headed Albatross Thalassarche chrysostoma chicks on Marion Island have been inspected for chicks presenting mouse wounds...

Relationships of wingtip shape, song-flight and mating success in male black-headed buntings Emberiza melanocephala
Wing design in birds is the result of different and potentially opposing natural selection pressures, such as those related to migration, predator...

Colour variation and taxonomy of Picumnus limae Snethlage, 1924 and P. fulvescens Stager, 1961 (Piciformes: Picidae)
Picumnus limae Snethlage, 1924 and Picumnus fulvescens Stager, 1961 are two similar species of piculets distinguished by their plumage colouration...

Assessing sex differences in behavioural flexibility in an endangered bird species: the Southern ground-hornbill (Bucorvus leadbeateri)
Since ecology influences the expression of cognitive traits, intra-specific variation in ecological demands can drive differences in cognition. This...

A taxonomic revision of Chotoy spinetail Schoeniophylax phryganophilus
Chotoy spinetail Schoeniophylax phryganophilus is widely distributed in southern and eastern South America. What was believed to be a geographically...

Repeatability and Validity of Phenotypic Trait Measurements in Birds
Phenotypic trait data play a central role in ecology and evolutionary research. The quality of trait data, and the findings of subsequent analyses,...

Effect of seaweed extract on avocado root growth, yield and post-harvest quality in far north Queensland, Australia
Seaweed extracts are proven to increase productivity in many agricultural crops, but there is limited research on their use in avocado production....

Epilogue: The Ocean in the Future of Humanity
The ocean occupies two-thirds of the surface of our planet, giving it the blue colour that easily distinguishes it from the rest of the known...

Dark heterochromia in adult masked lapwings is universal, asymmetrical and possibly slightly sexually dimorphic
Variations in eye colour in birds are poorly documented. We measured and characterised eyes of 25 birds in the hand (16° × 22.5° segments per eye),...

Prey ingestion rates revealed by back-mounted accelerometers in Eurasian spoonbills
BackgroundQuantifying foraging success in space and time and among individuals is essential for answering many ecological questions and may guide...

Capture tolerance: A neglected third component of aposematism?
Aposematism (considered here as an association between conspicuous colour patterns and the presence of a harmful secondary defence) has long been...

Assessment of morpho-cultural, genetic and pathological diversity of Rhizoctonia solani isolates obtained from different host plants
Rhizoctonia solani is a destructive soil borne plant pathogen that infects various crops including rice. A total of 35 isolates of R. solani from...

Doubled haploidy methodology for three forage grasses [crested wheatgrass (Agropyron cristatum (L.) Gaertn.), hybrid bromegrass (Bromus riparius x B. inermis), and meadow bromegrass (Bromus riparius Rehm.)]
Doubled haploidy (DH) methodology is used in many plant species to accelerate crop improvement and cultivar development; however not all species are...

Resampling reduces bias amplification in experimental social networks
Large-scale social networks are thought to contribute to polarization by amplifying people’s biases. However, the complexity of these technologies...
