Effectiveness of territorial protection categories in conserving an endemic island bird during population fluctuation

open access: yesConservation Science and Practice, EarlyView.
Static boundaries of protected areas failed to capture the Canary Islands stonechat's shifting distribution patterns. Abstract Protected areas represent cornerstones of biodiversity conservation on oceanic islands, yet their effectiveness for endemic species remains poorly evaluated. We assessed how various territorial protection categories conserve an

Meadow birds on organic and conventional arable farms in the Netherlands: abundance and nest success [PDF]

open access: yes, 2010
Intensification of agriculture is mentioned to be the key drive behind the decline of farmland birds on grassland and on arable land. This raises the question whether a less intensive system, such as organic, can stop or reverse these declines.

Exposure to the Oestrogenic Pollutant 17α‐Ethinyl Estradiol (EE2) Does Not Alter the Behaviour of a Coastal Marine Fish, Cristiceps australis

open access: yesEthology, EarlyView.
Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

The effect of static incubation on the yolk sac vasculature of the Japanese quail (Coturnix c. japonica) [PDF]

open access: yes, 2006
Static incubation affects early embryonic development with, notably, a reduction area vasculosa expansion and diminished sub-embryonic fluid (SEF) volume, effects produced during a ‘critical’ period (3-7 days in the chick) (Baggott et al., 2002).

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

open access: yesJournal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...
