Tree cover and geographic origin of tree species drive bird functional groups in urban environments

open access: yesWildlife Biology, EarlyView.
Urban trees provide habitat and resources for wild species in cities and support biodiversity provision of ecosystem services, among which insect control is particularly relevant. Predators of insects are promoted by the presence of trees and, in turn, may enhance biosecurity of the trees.

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]

open access: yes, 2016
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.

Reciprocal positive effects on parasitemia between coinfecting haemosporidian parasites in house sparrows

open access: yesBMC Ecology and Evolution, 2022
Background Hosts are often simultaneously infected with several parasite species. These co-infections can lead to within-host interactions of parasites, including mutualism and competition, which may affect both virulence and transmission.

Using programmable infusion pump in avian species – a validation methodology in geese

open access: yesWildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Concrete jungle to urban oasis: evaluating scale, vegetation cover, and aggregation of urban greenspaces on wildlife

open access: yesWildlife Biology, EarlyView.
Urban greenspaces are a haven for wildlife in densely populated cities. Wildlife use greenspaces for resource acquisition, shelter, and travel across urbanized landscapes. Greenspace metrics such as herbaceous or woody landcover, size, patchiness, and human land use influence species richness.

Abundance, temporal variation, and microhabitat use of the house sparrow, Passer domesticus (Passeriformes: Passeridae), in urban and anthropogenic environments in Northeastern Brazil [PDF]

open access: yesZoologia (Curitiba)
The increase in urbanization poses a significant threat to biodiversity, leading to the alteration of natural habitats and intensified competition between native and exotic species.

Fall Field Report, August–November 2016 [PDF]

open access: yes, 2016
As usual, there was quite a bit to chew over in the Fall Seasonal Report, although it was generally a pretty uneventful season, especially among waterfowl and shorebirds.

Rapid scavenging of avian carcasses in the desert Southwest: Implications for mortality surveys not associated with infrastructure

open access: yesWildlife Society Bulletin, EarlyView.
We placed 214 avian carcasses in a desert environment at locations not associated with infrastructure and monitored their removal by scavengers using camera traps. We found that 211 of the 214 carcasses were scavenged and median persistence time was 1.53 days. None of the predictor variables were informative of carcass persistence times.
