This study aims at assessing the serological cross-reactions existing between three mosquito-borne flaviviruses with avian reservoirs co-circulating in Europe: West Nile (WNV), Usutu (USUV) and Bagaza (BAGV). The is useful for a better interpretation of results diagnostics surveillance. Serum samples obtained from natural host, red-legged partridge (Alectoris rufa), experimentally infected WNV, USUV or BAGV were analysed using two commercially available WNV competition ELISAs suitable...
Flaviviruses have become increasingly important pathogens in Europe over the past few decades. A better understanding of spatiotemporal distribution flaviviruses France is needed to define risk areas and gain knowledge dynamics virus transmission cycles. Serum samples from 1014 wild boar 758 roe deer 16 departments (administrative units) collected 2009 2014 were screened for flavivirus antibodies using a competitive ELISA (cELISA) technique. found be positive or doubtful by cELISA then...
Abstract Migrating long distances requires time and energy, may interact with an individual's performance during breeding. These seasonal interactions in migratory animals are best described populations disjunct nonbreeding distributions. The black‐tailed godwit ( Limosa limosa ), which breeds agricultural grasslands Western Europe, has such a distribution: majority spend the season West Africa, while growing number winters north of Sahara on Iberian Peninsula. To test whether crossing...
Our study focuses on the Iberian ibex (Capra pyrenaica) from Sierra Nevada Natural Space (southern Spain), where sarcoptic mange is an endemic disease and animals are affected by a highly seasonal environment. aim was to distinguish between environmental influences variation in body weight, hematology, serum biochemistry ibex. We sampled 136 chemically immobilized male ibexes. The single effect of influenced hemoglobin, hematocrit, mean corpuscular volume, leukocytes, band neutrophils,...
Hybridization between closely related wild and domestic species is of great concern because it can alter the evolutionary integrity affected populations. The high allelic variability Major Histocompatibility Complex (MHC) loci usually excludes them from being used in studies to detect hybridization events. However, if a) parental don't share alleles, b) one possesses an exceptionally low number alleles (to facilitate analysis), then even MHC have potential hybrids. By genotyping exon2 class...
Bagaza virus (BAGV; synonymous to Israel turkey meningoencephalomyelitis virus, ITV) is a relevant arthropod-borne epornitic flavivirus. In its first emergence in Europe (southern Spain, 2010) BAGV caused an outbreak, severely affecting red-legged partridges and common pheasants. The effects (pathogenicity, role as reservoir host) of other European phasianids are unknown. To fill this gap, grey were experimentally infected with BAGV. clinical course the disease was severe, neurological...
Changes in agricultural practices have reshaped landscapes and triggered a drastic decline spatial temporal heterogeneity leading to changes habitat quality food resources for birds. However, the precise relationships between landscape changes, heterogeneity, preferences response those remain poorly known.We investigated patterns of selection causes over years 1997-2017 gray partridge Perdix perdix, an iconic farmland species which has experienced severe since 1950s. Using long-term...
Heterogeneity in host compatibility is one of the main hypotheses proposed to explain uneven resistance parasites and parasite load between hosts. It suggests that differences hosts modulate their predispositions as suitable environments for potential parasites. Interesting studies antiparasitic behavior have reported existence behavioral traits are capable removing foreign particles reducing success parasitic infections. These favor neatness, although little known about heterogeneity...
Sperm competition is a powerful evolutionary force, and understanding the factors that regulate testes characteristics may lead to better of variability in male reproductive success.We explored effects age, body condition season on relative mass Iberian ibex Capra pyrenaica.We analysed from 175 individuals, using model selection approach based Akaike's information criterion corrected for small sample size.The results suggest season, age influenced mass.Allocation was greatest rutting...
Nest predation is the main cause of reproductive failure, particularly in ground-nesting birds on farmlands. Understanding links between nest and habitat change can help design effective management schemes to constrain negative impact pressure birds. However, mechanisms underlying relationships landscape attributes, predator distribution, are still unclear. Here, we use an experimental approach examine effects distance hedgerow as well forest densities abundance major mesopredators ground...
As few studies have analysed local variability in populations of wild boar Sus scrofa Western Europe recent years, our understanding ecological processes currently affecting this species is limited. To analyse questions regarding abundance, we used information from 442 traditional drive hunts monitored throughout eight hunting periods the Pyrenees mountain range (Urdués, N Spain). Results showed temporal oscillations and a non–linear decrease 23% number seen per hunt between 2004 2011....
Distance sampling is being extensively used to estimate the abundance of animal populations. Nevertheless, great variety ways in which data can be analyzed may limit comparisons due lack standardization such protocols. In this study, influence analytical procedures for distance on density estimates and their precision was assessed. We have from 21 surveys mountain ungulates Iberian Peninsula, France Italian Alps. Data were with program 6.0. Our analyses show that estimated higher levels...
Most studies of lateralized behaviour have to date focused on active such as sensorial perception and locomotion little is known about postures, lying, that can potentially magnify the effectiveness reaction. Moreover, relative importance factors sex, age stress associated with social status in laterality now a subject increasing interest. In this study, we assess reproductive investment females lying Iberian ibex (Capra pyrenaica). Using generalized additive models under an...
Long-term variation of demographic parameters in four small game species Europe: opportunities and limits to test for a global pattern.For decades, decreases several populations some sedentary have been reported Europe.From the literature, we extracted mortality reproductive rates that were available European iconic species, grey partridge (Perdix perdix), black grouse (Tetrao tetrix), capercaillie (T.urogallus) brown hare (Lepus europaeus), examine how vary with time.Our study revealed need...
