Research on the rearing of bumblebees in artificial nests

Ethology Ecology & Evolution, 1994
Rearing trials on several Bombus species were carried out in 1990 and 1991. The purpose was to improve techniques of colony management and to observe colony growth and the behaviour of foraging workers. A total of 5 queens of Bombus hortorum (L.), 32 of B. humilis Ill., 93 of B. lapidarius (L.), 77 of B. pratorum (L.), 5 of B.

Is nest predation density dependent? A test using artificial nests

Canadian Journal of Zoology, 1992
Experiments using artificial nests to test whether predation varies with nest density were conducted in a northern hardwood forest in New Hampshire in June 1989. Nests were baited with quail eggs and placed at densities similar to and substantially higher than the range of natural nest densities.

Artificial Nest Experiments: Effects of Nest Appearance and Type of Predator

The Condor, 1987
Nest predation is a primary cause of nesting mortality for many bird species (Skutch 1949, 1966; Nice 1957; Ricklefs 1969; Nilsson 1984). Food limitation and competition also can affect nesting success (see reviews in Martin 1986, 1987). However, the primary role of nest predation in nesting mortality suggests that it can be a strong agent of selection

Effects of nest features and surrounding landscape on predation rates of artificial nests

Bird Study, 1999
Artificial nest predation experiments were carried out in northern Italy in woods which varied in size, isolation and surrounding landscape structure. Multivariate analyses, including logistic regression, showed that: (1) size and isolation of woods did not significantly affect predation rates; (2) nests on the edge of woods did not suffer higher ...
