How conspicuous are peacock eyespots and other colorful feathers in the eyes of mammalian predators?

PLoS One 2019 24;14(4):e0210924. Epub 2019 Apr 24.

Migratory Bird Center, Smithsonian Conservation Biology Institute, National Zoological Park, Washington DC, United States of America.

Colorful feathers have long been assumed to be conspicuous to predators, and hence likely to incur costs due to enhanced predation risk. However, many mammals that prey on birds have dichromatic visual systems with only two types of color-sensitive visual receptors, rather than the three and four photoreceptors characteristic of humans and most birds, respectively. Here, we use a combination of multispectral imaging, reflectance spectroscopy, color vision modelling and visual texture analysis to compare the visual signals available to conspecifics and to mammalian predators from multicolored feathers from the Indian peacock (Pavo cristatus), as well as red and yellow parrot feathers.

Parvalbumin-immunoreactive cells in the olfactory bulb of the pigeon: Comparison with the rat.

Anat Histol Embryol 2019 Apr 24. Epub 2019 Apr 24.

Department of Neurobiology, School of Medicine, Kangwon National University, Chuncheon, Republic of Korea.

The olfactory bulb (OB) shows special characteristics in its phylogenetic cortical structure and synaptic pattern. In the OB, gamma-aminobutyric acid (GABA), as an inhibitory neurotransmitter, is secreted from GABAergic neurons which contain parvalbumin (a calcium-binding protein). Many studies on the distribution of parvalbumin-immunoreactive neurons in the rodent OB have been published but poorly reported in the avian OB. Read More

Different responses of avian feeding guilds to spatial and environmental factors across an elevation gradient in the central Himalaya.

Ecol Evol 2019 Apr 14;9(7):4116-4128. Epub 2019 Mar 14.

Zhejiang Tiantong Forest Ecosystem National Observation and Research Station, School of Ecological and Environmental Sciences East China Normal University Shanghai China.

Although elevational patterns of species richness have been well documented, how the drivers of richness gradients vary across ecological guilds has rarely been reported. Here, we examined the effects of spatial factors (area and mid-domain effect; MDE) and environmental factors, including metrics of climate, productivity, and plant species richness on the richness of breeding birds across different ecological guilds defined by diet and foraging strategy. We surveyed 12 elevation bands at intervals of 300 m between 1,800 and 5,400 m a. Read More

Morphological and digestive adjustments buffer performance: How staging shorebirds cope with severe food declines.

Ecol Evol 2019 Apr 12;9(7):3868-3878. Epub 2019 Mar 12.

Department of Coastal Systems, NIOZ Royal Netherlands Institute for Sea Research and Utrecht University Texel The Netherlands.

Organisms cope with environmental stressors by behavioral, morphological, and physiological adjustments. Documentation of such adjustments in the wild provides information on the response space in nature and the extent to which behavioral and bodily adjustments lead to appropriate performance effects. Here we studied the morphological and digestive adjustments in a staging population of migrating Great Knots in response to stark declines in food abundance and quality at the Yalu Jiang estuarine wetland (northern Yellow Sea, China).

Island biogeography theory explains the genetic diversity of a fragmented rock ptarmigan () population.

Ecol Evol 2019 Apr 27;9(7):3837-3849. Epub 2019 Feb 27.

Department of Natural Sciences and Environmental Health University of South-Eastern Norway Bø i Telemark Norway.

The island biogeography theory is one of the major theories in ecology, and its applicability to natural systems is well documented. The core model of the theory, the equilibrium model of island biogeography, predicts that species diversity on an island is positively related to the size of the island, but negatively related by the island's distance to the mainland. In recent years, ecologists have begun to apply this model when investigating genetic diversity, arguing that genetic and species diversity might be influenced by similar ecological processes.

Worldwide insect declines: An important message, but interpret with caution.

Ecol Evol 2019 Apr 5;9(7):3678-3680. Epub 2019 Apr 5.

Department of Zoology, Conservation Science Group University of Cambridge Cambridge UK.

A recent paper claiming evidence of global insect declines achieved huge media attention, including claims of "insectaggedon" and a "collapse of nature." Here, we argue that while many insects are declining in many places around the world, the study has important limitations that should be highlighted. We emphasise the robust evidence of large and rapid insect declines present in the literature, while also highlighting the limitations of the original study. Read More

Poly-ADP Ribosyl Polymerase 1 (PARP1) Regulates Influenza A Virus Polymerase.

Adv Virol 2019 19;2019:8512363. Epub 2019 Mar 19.

Department of Biological Sciences, University of Alaska Anchorage, Anchorage, Alaska, USA.

Influenza A viruses (IAV) are evolutionarily successful pathogens, capable of infecting a number of avian and mammalian species and responsible for pandemic and seasonal epidemic disease in humans. To infect new species, IAV typically must overcome a number of species barriers to entry, replication, and egress, even while virus replication is counteracted by antiviral host factors and innate immune mechanisms. A number of host factors have been found to regulate the replication of IAV by interacting with the viral RNA-dependent RNA polymerase (RdRP). Read More

Evaluation of a Chicken 600K SNP genotyping array in non-model species of grouse.

Sci Rep 2019 Apr 23;9(1):6407. Epub 2019 Apr 23.

U.S. Geological Survey, Fort Collins Science Center, Ft. Collins, Colorado, USA.

The use of single nucleotide polymorphism (SNP) arrays to generate large SNP datasets for comparison purposes have recently become an attractive alternative to other genotyping methods. Although most SNP arrays were originally developed for domestic organisms, they can be effectively applied to wild relatives to obtain large panels of SNPs. In this study, we tested the cross-species application of the Affymetrix 600K Chicken SNP array in five species of North American prairie grouse (Centrocercus and Tympanuchus genera). Read More

Quantitative Analyses Reveal Novel Roles for Glycosylation in a Major Enteric Bacterial Pathogen.

MBio 2019 Apr 23;10(2). Epub 2019 Apr 23.

Department of Pathogen Biology, London School of Hygiene and Tropical Medicine, London, United Kingdom

In eukaryotes, glycosylation plays a role in proteome stability, protein quality control, and modulating protein function; however, similar studies in bacteria are lacking. Here, we investigate the roles of general protein glycosylation systems in bacteria using the enteropathogen as a well-defined example. By using a quantitative proteomic strategy, we were able to monitor changes in the proteome when glycosylation is disrupted. Read More

Experimental evidence of non-random nest material selection in pied flycatchers.

Behav Processes 2019 Apr 20. Epub 2019 Apr 20.

Division of Biological Sciences, University of Montana, Missoula, MT 59812, USA. Electronic address:

Nest building is a taxonomically widespread behaviour that consists of the construction of a suitable receptacle with collected materials for the incubation of eggs and sometimes for the raising of offspring. The use of specific nest materials has important fitness consequences for avian parents and offspring because they help to determine the thermal, parasitic and bacterial environment within nests and may also influence parental investment via intraspecific signalling. However, we presently know very little about the process by which nest materials are selected from the wider environment and specifically, it is unclear whether wild birds randomly or non-randomly select nest materials in relation to their local availability.

Department of Evolutionary Biology, Evolutionary Biology Centre (EBC), Science for Life Laboratory, Uppsala University, SE-752 36 Uppsala, Sweden.

Avian genomes have perplexed researchers by being conservative in both size and rearrangements, while simultaneously holding the blueprints for a massive species radiation during the last 65 million years (My). Transposable elements (TEs) in bird genomes are relatively scarce but have been implicated as important hotspots for chromosomal inversions. In zebra finch (), long terminal repeat (LTR) retrotransposons have proliferated and are positively associated with chromosomal breakpoint regions. Read More

Adaptive radiation and the evolution of nectarivory in a large songbird clade.

Evolution 2019 Apr 23. Epub 2019 Apr 23.

Center for Macroecology, Evolution and Climate, Natural History Museum of Denmark, University of Copenhagen, Universitetsparken 15, DK-2100, Copenhagen, Denmark.

The accumulation of exceptional ecological diversity within a lineage is a key feature of adaptive radiation resulting from diversification associated with the subdivision of previously underutilized resources. The invasion of unoccupied niche space is predicted to be a key determinant of adaptive diversification, and this process may be particularly important if the diversity of competing lineages within the area, in which the radiation unfolds, is already high. Here, we test whether the evolution of nectarivory resulted in significantly higher rates of morphological evolution, more extensive morphological disparity, and a heightened build-up of sympatric species diversity in a large adaptive radiation of passerine birds (the honeyeaters, ca.

Water containing organic material has been shown to increase the persistence of the avian pathogenic protozoa, . We hypothesized that the decrease in dissolved oxygen due to microbes in the organic material could increase persistence of the microaerophilic trichomonads. Using simulated birdbaths, we determined 1) the levels of dissolved oxygen in distilled water with various amounts of organic material, 2) the concentration of the oxygen-scavenging enzyme Oxyrase needed to achieve the dissolved oxygen levels obtained in organic material contaminated water, and finally, 3) the persistence of two isolates in Oxyrase®-supplemented water.

Haematological traits co-vary with migratory status, altitude and energy expenditure: a phylogenetic, comparative analysis.

Sci Rep 2019 Apr 23;9(1):6351. Epub 2019 Apr 23.

Department of Biological Sciences, Simon Fraser University, 8888 University Drive, Burnaby, British Columbia, V5A 1S6, Canada.

Aerobic capacity is assumed to be a main predictor of workload ability and haematocrit (Hct) and haemoglobin (Hb) have been suggested as key determinants of aerobic performance. Intraspecific studies have reported increases in Hct and Hb in response to increased workload. Furthermore, Hct and Hb vary markedly among individuals and throughout the annual cycle in free-living birds and it has been suggested that this variation reflects adaptive modulation of these traits to meet seasonal changes in energy demands.

High egg rejection rate in a Chinese population of grey-backed thrush ().

Zool Res 2019 May 28;40(3):226-230. Epub 2019 Mar 28.

everal previous studies have indicated that nest sanitation behavior is a general adaptation in altricial birds, with egg recognition capacity evolving as a specific response to interspecific brood parasitism (IBP). However, a recent study suggested an alternative hypothesis, concluding that conspecific brood parasitism (CBP) selects for egg rejection in thrushes, with IBP as a by-product. In the present study, we used a spectrophotometer to quantify egg coloration and egg mimicry and performed artificial parasitism experiments in the grey-backed thrush (). Read More
