Young vertebrates have limited capacity to synthesize antibodies and are dependent on the protection of maternally transmitted for humoral disease resistance early in life. However, mothers may enhance fitness by priming their offspring's immune systems elevate resistance. Transgenerational induced defences been documented plants invertebrates, but maternal offspring immunity has essentially neglected. To test ability stimulate offspring, we manipulated antigen exposure a wild population...
Young vertebrates are dependent primarily on innate immunity and maternally derived antibodies for immune defense. This reliance the associated inflammatory response often leads to reduced growth rates after antigenic challenge. However, if offspring have maternal that recognize an antigen, these should block stimulation of reduce suppression. To determine whether and/or antigen exposure affect antibody transmission growth, female Japanese quail (Coturnix japonica) their newly hatched chicks...
Abstract A central assumption in ecological immunology is that immune responses are costly, with costs manifesting directly (e.g., increases metabolic rate and increased amino acid usage) or as tradeoffs other life processes reduced growth reproductive success). Across taxa, host longevity, timing of maturity, effort affect the organization systems. It reasonable, therefore, to expect these related factors should also activation costs. Specifically, species spread their breeding efforts over...
Climate change has affected the seasonal phenology of a variety taxa, including that migratory birds and their critical food resources. However, whether climate-induced changes in breeding affect individual fitness, how these might therefore influence selection on date remain unresolved. Here, we use 36-yr dataset from long-term, individual-based study House Wrens (Troglodytes aedon) to test timing avian seasons is associated with annual temperature, which have increased small but...
ABSTRACT There is growing interest in studying hormones beyond single ‘snapshot’ measurements, as recognition that individual variation the endocrine response to environmental change may underlie many rapid, coordinated phenotypic changes. Repeated measures of hormone levels individuals provide additional insight into flexibility – is, how modulate environment. The ability quickly and appropriately modify phenotype predicted be favored by selection, especially unpredictable environments....
Summary The ability to resist infection is an important component of survival and lifetime reproductive success. Mounting maintaining immunological defence assumed be energetically costly nutritional resources expended on immune function may induce trade‐offs with other expensive functions, including reproduction. Resource limitation even have transgenerational effects during reproduction because mothers are the primary source humoral immunity in young vertebrates. To determine whether...
Abstract Single components of the immune system are widely used to assess function in free‐living vertebrates. However, as different immunological triggered by types threats and may be regulated independently, there is little reason assume that they should respond similarly if challenged. We investigated whether three commonly assayed responses, cutaneous activity (phytohaemagglutinin assay), antibody response (tetanus toxoid immunization), plasma bactericidal ( Escherichia coli killing)...
Maternally transferred antibodies have been documented in a wide range of taxa and are thought to adaptively provide protection against parasites pathogens while the offspring immune system is developing. In most birds, transfer occurs when females deposit immunoglobulin Y into egg yolk, it proportional amount female's plasma. Maternal can short-term passive as well specific nonspecific immunological priming, but high levels maternal antibody result suppression offspring's humoral response....
Immunological reagents for wild, non-model species are limited or often non-existent many species.In this study, we compare the reactivity of a new anti-passerine IgY secondary antibody with existing antibodies developed use birds. Samples from 41 following six avian orders were analysed: Anseriformes (1 family, 1 species), Columbiformes 2 Galliformes Passeriformes (16 families, 34 Piciformes species) and Suliformes species). Direct ELISAs performed to detect total using goat IgY,...
Stress exposure during development can impact both the expression of individual traits and associations between traits, but whether stress results in stronger or weaker is unclear. In this study, we examined within- among-trait for morphological physiological zebra finches (Taeniopygia guttata) exposed to corticosterone (CORT) nestling fledging stages as well control birds. Birds CORT exhibited within-trait correlations over time among traits. We found preliminary evidence that birds died...
Secondary sexual traits may convey information about individual condition. We assessed the capacity for immune challenge with lipopolysaccharide (LPS) or keyhole limpet hemocyanin (KLH) during prenatal and early postnatal stages to impact beak color development expression in captive zebra finches. In addition, we tested whether adult impacted color, if early-life experience was influential. Immune KLH life slowed of red coloration, males challenged as nestlings had reduced coloration adults....
