Landscape Structure Shapes the Equilibrium Between Migratory and Sedentary Species in Avian Breeding Communities Along an Altitudinal Gradient

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Human land use shapes landscapes and threatens avian biodiversity, yet its interaction with altitudinal gradients and the consequences for the assembly of long‐distance migratory and sedentary bird communities remain poorly understood. Location Southern France. Taxon Avian breeding communities.

BREEDING STATUS AND NEST CHARACTERISTICS OF ROSERINGED (PSITTACULA KRAMERI) AND ALEXANDRINE PARAKEETS (PSITTACULA EUPATRIA) IN ISTANBUL’S CITY PARKS

open access: yesApplied Ecology and Environmental Research, 2019
Invasive non-native parakeet populations are increasing throughout Europe with proved negative impact on native fauna and Turkey is no exception. Rose-ringed and Alexandrine parakeets have established populations in Turkey's large cities but even basic distribution, abundance and breeding behaviour information is missing. This study aims at determining

Behavioural shifts of bats during urban music festivals

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
We investigated how large outdoor music festivals affect bat activity in an urban green spaces. Although total nightly activity did not decline on concert nights, we showed activity during concert hours dropped significantly—by up to 42% for some species.

Socio‐Economic Status and Non‐Native Species Drive Bird Ecosystem Service Provision in Urban Areas

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
Birds bring important benefits to people, like pest control and aesthetic enjoyment. We studied birds in cities across Spain and Portugal to see how income levels affect the benefits people get from nature. We found that higher income areas tended to have more bird species but, surprisingly, fewer of these benefits, while places with non‐native birds ...
