Lipid peroxidation products are widely used as markers of oxidative damage in the organism. To properly interpret information provided by these markers, it is necessary to know potential sources bias and control confounding factors. Here, we investigated relationship between two indicators lipid mobilization (circulating levels triglycerides cholesterol) common (plasma malondialdehyde hydroperoxides; latter estimated from d-ROMs assay kit). The following five avian species were studied:...
We explore the presence of zoonotic flaviviruses (West Nile virus (WNV) and Usutu (USUV)) neutralizing antibodies in rarely studied passerine bird species. report, for first time Europe, WNV-specific red avadavat cetti's warbler, USUV yellow-crowned bishop. The evidence WNV circulating resident migratory species has implications both animal public health. Future outbreaks avian reservoir hosts may occur passerines should be considered as priority target flavivirus surveillance programmes.
Abstract Stress during early development can induce substantial long‐term effects in organisms. In the case of birds, despite growth compensations, nestlings reared under harsh conditions typically show reduced survival chances adulthood. It has been proposed that environmental early‐life stressors could affect longevity via on telomere length, possibly mediated through oxidative stress. However, link between these processes is not clear. this study, we experimentally manipulated brood size...
Female birds may adjust their offspring phenotype to the specific requirements of environment by differential allocation physiologically active substances into yolks, such as androgens. Yolk androgens have been shown accelerate embryonic development, growth rate and competitive ability nestlings, but they can also entail immunological costs. The balance between costs benefits androgen is expected depend on nestling environment. We tested this hypothesis in a multibrooded passerine, spotless...
Several techniques in ecological immunology have been used to assess bird immunocompetence thus providing useful information understand the contribution of immunological system life-history decisions. The phytohaemagglutinin (PHA)-skin test has most widely employed technique being interpreted as sole result T lymphocytes proliferation and hence evaluate acquired capacity. However, presence high numbers phagocytic cells swelling point cast some doubt about such an assumption. To address this...
Avian malaria and related haemosporidians (genera Haemoproteus, Plasmodium Leucocytozoon) infect most clades of bird. Although these parasites are present in almost all continents, they have been irregularly studied across different geographical regions. Despite the high bird diversity Asia, avian this region is largely unknown. Moreover, anthropogenic changes to habitats tropical regions may a profound impact on overall composition haemosporidian communities. Here we analyzed host...
Avian egg yolks contain various amounts of maternally derived androgens that can modify offspring phenotype and adjust their development to posthatching environment. Seemingly adaptive variation in yolk androgen levels with respect breeding density conditions or male attractiveness has been found numerous studies. One important consideration overlooked previous research is the likely non-linear nature hormone effects. To examine possible complex dose-response effects maternal on chick...
Oscine birds preferentially respond to certain sounds over others from an early age, which focuses subsequent learning onto sexually relevant songs.1,2,3 Songs vary both across species and, due cultural evolution, among populations of the same species. As a result, song responses are expected be shaped by selection avoid fitness costs cross-species learning4 and promote population-typical songs.5 These sources not mutually exclusive but can result in distinct geographic patterns juvenile...
Avian malaria and related haemosporidian parasites can negatively impact fitness in many songbirds. Research on the infection its physiological costs their avian hosts is heavily skewed toward native passerines, with exotic species underrepresented. However, introduced may carry spread new pathogens to species, play a role parasite transmission cycle invaded bird communities as pathogen reservoir. Here, we molecularly assess prevalence diversity of three wetland passerines (the Red Avadavat...
Abstract Aim The increasing spread of vector‐borne diseases has resulted in severe health concerns for humans, domestic animals and wildlife, with changes land use the introduction invasive species being among main possible causes this increase. We explored several ecological drivers potentially affecting local prevalence richness avian malaria parasite lineages native introduced house sparrows ( Passer domesticus ) populations. Location Global. Time period 2002–2019. Major taxa studied...
Characterizing the diversity and structure of host-parasite communities is crucial to understanding their eco-evolutionary dynamics. Malaria related haemosporidian parasites are responsible for fitness loss mortality in bird species worldwide. However, despite exhibiting greatest ornithological biodiversity, avian haemosporidians from Neotropical regions quite unexplored. Here, we analyze genetic (Plasmodium Haemoproteus) 1,336 individuals belonging 206 explore differences parasite lineages...
La investigación de la influencia infección parasitaria en los animales requiere estimaciones precisas del estado individuos. En el caso parásitos intestinales, suele determinarse indirectamente por presencia y abundancia propágulos parásito las heces. Sin embargo, excreción se ve afectada patrones ontogenéticos, diarios estacionales que rara vez identifican, especialmente polluelos paseriformes silvestres. este trabajo investigamos efecto edad hora día sobre ooquistes coccidios estornino...
Environmental variation can shape the gut microbiome, but broad/large-scale data on among and within-population heterogeneity in microbiome associated environmental factors of wild populations is lacking. Furthermore, previous studies have limited taxonomical coverage, knowledge about avian microbiomes still scarce. We investigated large-scale adult great tits across species' European distribution range. collected fecal samples to represent used 16S rRNA gene sequencing characterize...
To avoid competition for parental care, brood-parasitic Common Cuckoo (Cuculus canorus) nestlings evict all of the host's eggs and within a few days after hatching. Little is known about physiological effects eviction behavior on cuckoo nestling's oxidative balance or age-related variation in plasma status testosterone level developing birds. We examined whether was related to prior effort quantified reactive oxygen metabolites, nonenzymatic antioxidant capacity, concentration at various...
Avian embryos are exposed to yolk androgens that incorporated into the egg by ovulating female. These steroids can affect several aspects of embryo development, often resulting in increases overall size or speed growth different traits. However, studies suggest they also entail immune costs offspring. In this study, we explored whether variation androgen concentration affected measures constitutive and cell-mediated axes spotless starling (Sturnus unicolor). Using a within-brood design,...
Abstract Begging in birds is a complex behaviour used by nestlings to solicit feeds from caregivers. Besides calling when parents are present, of some species also perform less conspicuous repeat calls absent. The fact that these produced not at the nest does mean cannot hear them they approach or forage its vicinity. In this study, we experimentally investigated relationship between parent‐absent ( ARC ) and frequency parental visits, considering parent/offspring communication as possible...
Abstract Urbanization constitutes one of the major transformations natural habitats, creating new areas characterized by multiple potential wildlife stressors. Birds that live in highly anthropized zones are confronted with physiological and behavioural challenges caused these Here, we investigated if several health parameters differed between three subpopulations tree sparrow nestlings subjected to different levels anthropogenic pollution, particularly noise pollution: a quiet rural area,...
Floaters constitute the sexually mature but non-breeding part of populations. Despite being ubiquitous in most species, knowledge about floaters is scarce. Ignoring this significant number individuals may strongly bias our understanding population dynamics and sexual selection processes. We used spotless starling (Sturnus unicolor) to examine whether phenotypical non-phenotypical variables from early adult life predict reproductive status, focusing on earliest age at which start breed, when...
