adverse effects; adverse outcome pathways; birds; developmental stages; dose response; environmental science; fish; mortality; regression analysis; transcriptional activation
Abstract:
... Dioxin-like compounds (DLCs) elicit adverse effects through activation of the aryl hydrocarbon receptor (AHR). Prior investigations demonstrated that sensitivity to activation of AHR1 in an in vitro AHR transactivation assay is predictive of early life stage mortality among birds. The present study investigated the link between sensitivity to activation of AHR1s and AHR2s and early life stage mort ...

Falco peregrinus; birds; juveniles; Gulf of Mexico
Abstract:
... In October 2017, we opportunistically observed up to 50 Peregrine Falcons (Falco peregrinus) on a ship moored in the western Gulf of Mexico. All birds we aged were juveniles, and they hunted from the ship, frequently perching extremely close to one another (<1 m apart) on cables. Both the number of birds and also the very short inter-individual distances when perching make these observations unusu ...

Abstract:
... Road-salt runoff is an increasing problem in areas of North America that receive snow. Its effects include groundwater salinization, loss or reduction in lake turnover, and changes in soil structure. Road-salt runoff can affect biotic communities by causing changes in the composition of fish or aquatic invertebrate assemblages. It also poses threats to birds, mammals, and roadside vegetation. ...

Abstract:
... The Wryneck Jynx torquilla has undergone one of the largest bird species’ declines in Europe as a consequence of agricultural intensification; however, in some regions it still occurs in intensively managed permanent crops (e.g. vineyards). Considering the conservation status of the Wryneck and the increasing extent and intensification of permanent crops over Europe, investigating the habitat sele ...

Abstract:
... Life history traits differ between organisms living in the tropics, Northern and Southern Hemispheres, and sexual selection is thought to be stronger close to the equator than in temperate regions. Although birds are often supposed to be more brightly coloured in the tropics, the current evidence of geographic variation in the intensity of sexual selection and sex‐specific natural selection is equ ...

Abstract:
... Urbanization is one of the most important global trends which causes habitat reduction and alteration which are, in turn, the main reasons for the reduced structural and functional diversity in urbanized environments. Predation is one of the most important ecological functions because of its community-structuring effects. According to previous studies effects of urbanization on predation rates app ...

... The codling moth Cydia pomonella L. (Lepidoptera: Tortricidae) is a major economic pest in organic apple orchards. Observational methods, prey removal experiments and correlative experiments with exclosures or nest boxes have demonstrated that birds contribute to the removal of this insect pest. However, the majority of research conducted in the last several decades has taken place outside of the ...
