Nest-niche differentiation in two sympatric columbid species from a Mediterranean Tetraclinis woodland: Considerations for forest management

摘要: Abstract Studies of niche partitioning among Columbid species have mainly addressed food habits and foraging activities, while in relation to nest-niche differentiation has been little studied. Here we investigate whether two sympatric columbid species—Woodpigeon (Columba palumbus) Turtle dove (Streptopelia turtur)—occupy similar niches. A total 74 nests were monitored: 37 for each species. The study, conducted June 2016, attempted determine the factors that may play a role Moroccan Thuya (Tetraclinis articulata) forest. We used Principal Component Analysis (PCA) Linear Discriminant (LDA) test relevance nest placement, proximity resources, forest edge human presence variables distribution results show substantial segregation T. articulata nest-trees selected by Woodpigeons doves, with selection depending primarily on tree size height. Observed diminish potential competition between these enhance opportunities their coexistence. Management policies practices aimed at ensuring mixed-sized class trees must be prioritized. recommend additional studies designed to: (1) reproduce same experimental approach other Mediterranean forests improve our understanding effects different levels anthropogenic disturbance breeding behaviour game species; (2) better understand spatio-temporal dynamics Woodpigeon coexistence region; (3) identify extent effect management site occupancy.
