Strong diel variation in the activity of insect taxa sampled by Malaise traps

Ecological Entomology, EarlyView.
Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

A marker suitable for sex-typing birds from degraded samples [PDF]

, 2015
A new primer set was developed for sex-typing birds, Z37B. This primer set was designed to amplify alleles of small size to render it suitable for sex-typing degraded samples, including shed feathers.

Behavioural and fitness effects of experimental immune activation during incubation in a wild passerine

Ibis, EarlyView.
Incubation is vital for avian embryo development but demands significant parental investment, potentially at the cost of self‐maintenance and immune function. For example, the acute phase response (APR), a systemic reaction against inflammation, infection or tissue injury, can trigger sickness behaviours such as reduced activity and foraging.

Warm and cool temperatures decrease early‐life telomere length in wild pied flycatchers

Journal of Avian Biology
Climate change represents a major challenge for avian species. It is characterized by an increase in average ambient temperatures, but also by an increase of extreme weather events, such as heatwaves and cold snaps.

Increased songbird nest depredation due to Aleppo pine (Pinus halepensis) encroachment in Mediterranean shrubland

BMC Ecology, 2019
Background In recent decades, a decrease of passerine densities was documented in Mediterranean shrublands. At the same time, a widespread encroachment of Aleppo pines (Pinus halepensis) to Mediterranean shrubland occurred.

Radar studies of bird migration [PDF]

Observations of bird migration with NASA radars were made at Wallops Island, Va. Simultaneous observations were made at a number of radar sites in the North Atlantic Ocean in an effort to discover what happened to those birds that were observed leaving ...

Reproductive consequences of mate retention and divorce in a short‐lived migratory passerine

Ibis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.

Information on bird navigation obtained by British long range radars [PDF]

Radar observations of the migratory habits of passerine birds over a 10 year period are presented. The relationships between intensity of cloud cover and the frequency and density of migration are illustrated.
