Ecological Applications, Volume 36, Issue 4, June 2026.Abstract Biological invasions often generate complex ecological paradoxes, particularly when invasive species act as ecosystem engineers that simultaneously compete with and benefit native communities. Understanding these dual dynamics is critical for managing urban biodiversity.

Animal Biodiversity and Conservation, 2019 Stable isotope analyses (SIAs) have been widely used in recent years to infer the diet of many species. This isotopic approach requires using diet to tissue discrimination factors (DTDFs) for each prey type and predator tissue, i.e., to determine the ...

Beyond species loss: Community reshuffling shapes biodiversity along the urban–rural gradient
Journal of Applied Ecology, Volume 63, Issue 6, June 2026.Our results indicate that species turnover is a general ecological mechanism shaping vertebrate communities along the urban gradient, driven by taxon‐ and species‐specific responses to environmental and spatial features. Community differences primarily reflect habitat suitability rather than dispersal limitation, highlighting the potential of targeted ...

Journal of Biosciences, 2002 Formoguanamine (2,4-diamino-s-triazine) was known to be an effective chemical agent in inducing blindness in poultry chicks, but not in adult birds. The present study was undertaken to demonstrate the influences, if any, of this chemical on the visual performance and retinal histology in an adult sub-tropical wild bird the roseringed parakeet ...

Applied 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

Journal 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.

Crowding in the city: losing and winning competitors of an invasive bird. [PDF]
PLoS ONE, 2014 Invasive species can take advantage of resources unexploited by natives (opportunism hypothesis) or they can exploit the same resources but more aggressively or efficiently (competition hypothesis), thus impacting native species.
