Balancing conflict and coexistence: Interactions between invasive monk parakeets and native urban birds

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.

The first complete mitogenome of Indian ringneck (Psittacula krameri) demonstrates close phylogenetic relationship with Eclectus parrot

Mitochondrial DNA. Part B. Resources, 2019
This study was aimed to sequence the first complete mitochondrial genome from an Indian ringneck parrot (Psittacula krameri). The mitogenome sequence was circular and 16,413 bp in length. In comparison to other available mitogenome sequences belonging to

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 ...

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

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.

Sarcocystis falcatula infection in ringneck parakeets (Psittacula krameri) in Minas Gerais, Brazil

Brazilian Journal of Veterinary Pathology
Sarcocystis falcatula is an Apicomplexa protozoan parasite recognized for its pathogenicity in birds. This microorganism has a complex life cycle involving definitive hosts, such as marsupials from the Didelphidae family, and intermediate hosts, which ...
