Influence of Tree Species on Frequency of Trap-Nest Use by \u3ci\u3ePassaloecus\u3c/i\u3e Species (Hymenoptera: Sphecidae) [PDF]
Habitat selection by Passaloecus spp. based upon tree species used as stations for artificial nesting sites were studied. Data suggest that Passaloecus areolatus preferred Juglans and that P.

Effects of Nest Location on Depredation of Artificial Arboreal Nests
Depredation on artificial arboreal nests was studied in 1-ha aspen (Populus spp.) plots on a ruffed grouse (Bonasa umbellus) management area in central Pennsylvania from May to August 1985. Predation was evaluated with respect to 2 factors associated with nest placement: height of nest aboveground and plot age.

Ground Nesting in Recultivated Forest Habitats — A Study with Artificial Nests [PDF]
The study was carried out in the outskirts of the town of Pecs (southern Hungary) in a recultivated for- mer coal mine. Bordered by Turkey Oak forests, this open area forms a wedge-shaped clearing in that woodland. Since trees and taller shrubs are rare in the area, it is mainly ground nesting bird species that occur in the clearing.

Evaluating the efficacy of carbachol at reducing corvid predation on artificial nests
Nest predation often limits recovery of threatened and endangered birds, especially ground‐nesting species. Accordingly, a variety of techniques are used to reduce the impact of nest predation on listed species.

Aromatic Plants in Eurasian Blue Tit Nests: The ‘Nest [PDF]
The ‘Nest Protection Hypothesis’ suggests that some birds add aromatic plants to their nests to repel or kill ectoparasites. This behavior has been described for several species, including the Eurasian Blue Tit (Cyanistes caeruleus).

Frog foams and natural protein surfactants [PDF]
Foams and surfactants are relatively rare in biology because of their potential to harm cell membranes and other delicate tissues. However, in recent work we have identified and characterized a number of natural surfactant proteins found in the foam ...

Artificial nest predation rates vary depending on visibility in the eastern Brazilian Amazon [PDF]
Observational and experimental studies have shown that increased concealment of bird nests reduces nest predation rates. The objective of the present study was to evaluate differences in predation rates between two experimental manipulations of ...

Assessing the use of artificial nests for predicting predation pressure in New Zealand forest fragments : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Ecology at Massey University [PDF]
Using artificial nests to predict the predation pressure on natural bird nests has been the subject of over 400 publications, the vast majority quantifying aspects that affect nest success.
