Summary edit

Description
English: Relationship between blood lead concentrations in common ravens and date in 2011 and 2012. Dot size is proportional to the log of the sample size. Error bars represents SE. Dotted lines represent the 95%CI. The light blue barplot illustrates the cumulative number of rifle-shot moose in the hunting area selected for the study. Ravens with no sign of clinical contamination were reported to have lead concentration <100 µg.L−1 (horizontal red dashed line) according to Craighead D, Bedrosian B (2008) Blood lead levels of Common Ravens with access to big-game offal. Journal of Wildlife Management 72: 240–245.
Français : Schéma montrant la relation entre les concentrations de plomb dans le sang (plombémie) chez les corbeaux communs en 2011 et 2012 et le nombre d'orignaux (élans) tués dans la saison de chasse (dans une région de l'ouest du Québec)

La taille des points est proportionnelle au log de la taille de l'échantillon. Les barres d'erreur sont représentées . Les lignes pointillées représentent l'Indice de confiance (IC) à 95%. La zone bleu clair illustre le nombre cumulé d'orignaux abattus dans la zone de chasse sélectionnée pour l'étude.

(daprès Craighead D et de Bedrosian B (2008), les grands corbeaux ayant accès aux abats de gros gibier ne présentant pas de signes cliniques de contamination clinique présentaient une concentration en plomb de moins de 100 μg.L-1 (ligne pointillée horizontale rouge) .[Craighead D, Bedrosian B (2008) Blood lead levels of Common Ravens with access to big-game offal.
