Genetic and morphometric divergence of an invasive bird: the introduced house sparrow (Passer domesticus) in Brazil. [PDF]

open access: yesPLoS One, 2012
Introduced species are interesting systems for the study of contemporary evolution in new environments because of their spatial and temporal scales. For this study we had three aims: (i) to determine how genetic diversity and genetic differentiation of ...

Environmental factors influence both abundance and genetic diversity in a widespread bird species. [PDF]

open access: yes, 2013
Genetic diversity is one of the key evolutionary variables that correlate with population size, being of critical importance for population viability and the persistence of species. Genetic diversity can also have important ecological consequences within

Diet contributes to urban-induced alterations in gut microbiota : experimental evidence from a wild passerine [PDF]

open access: yes, 2020
Urban sprawl increasingly affects the ecology of natural populations, including host-microbiota interactions, with observed differences in the gut microbiota between urban and rural hosts.

Supplementary feeding increases nestling feather corticosterone early in the breeding season in house sparrows [PDF]

open access: yes, 2017
Several studies on birds have proposed that a lack of invertebrate prey in urbanized areas could be the main cause for generally lower levels of breeding success compared to rural habitats.

Mitochondrial heteroplasmy in an avian hybrid form (Passer italiae: Aves, Passeriformes) [PDF]

open access: yes, 2019
Mitochondrial heteroplasmy is the result from biparental transmission of mitochondrial DNA (mtDNA) to the offspring. In such rare cases, maternal and paternal mtDNA is present in the same individual.

Comparison of predation by two suburban cats in New Zealand [PDF]

open access: yes, 2017
To study the effects domestic cats may have on surrounding wildlife, a complete list was made of 558 items caught in the garden or brought into the house by one cat over 17 years, from 1988 to 2005.
