A Push-pull Protocol to Reduce Colonization of Bird Nest Boxes by Honey Bees

Preventing colonization of bird nest boxes by invasive Africanized honey bees is important for conservation efforts of nest-site limited birds. We provide an integrated pest management approach to "push" bees away from nest boxes with a repellant insecticide, permethrin, and "pull" them toward pheromone baited swarm traps.

We demonstrate the utility of nest building behavior in laboratory mice as an indicator of welfare. Nest scoring is a sensitive technique that is altered by temperature, illness, and aggression. The time to integrate into nest test (TINT) is a simple cage-side assessment that can detect postoperative pain.

Burrowing, nesting, and hoarding are species-typical activities that mice readily perform in the laboratory. This article describes how they can be easily and cheaply assessed. These protocols are extremely sensitive to mouse strain, brain lesions and diseases. Moreover they constitute “environmental enrichment” for the mice, and embody the “Refinement” aspect of the “3 Rs”18.

Nested-PCR to Detect a Specific Viral Genomic Sequence

This video describes nested polymerase chain reaction, a technique that consists of two sequential PCR amplification processes using two primer sets. The first set of primers is intended to anneal to sequences upstream of the second set, resulting in selective amplification of specific gene sequences. This PCR is more sensitive and specific than a normal PCR and is widely used as a detection technique for various diseases.
FAQs
Cavity choice depends on several physical and protective features rather than location alone. Birds may respond to the cavity’s size, entrance shape, degree of shelter, and ability to reduce predator exposure. These characteristics help determine whether an opening provides a suitable environment for nesting and raising young, making cavity structure an important link between habitat conditions and reproductive opportunities.
Species that excavate cavities in dead or decaying wood can create nesting opportunities for birds unable to make their own enclosed sites. After an excavated cavity is abandoned, other species may use it, linking the activities of primary excavators with the availability of shelter for a broader bird community. This dependence makes dead wood an important habitat component.
Their nesting opportunities depend on habitat features such as mature trees, dead or decaying wood, natural openings, and protected spaces. When those features decline, suitable cavities may become less available, reflecting habitat degradation or loss. Consequently, changes in these birds can help researchers evaluate forest structure, biodiversity, and the ecological effects of environmental change.
Researchers can relate the presence and nesting opportunities of these birds to conditions shaped by forest management, including the availability of mature trees and decaying wood. This approach helps reveal whether management practices preserve or reduce important habitat structure. The birds therefore provide biological context for assessing how changes in forests influence biodiversity rather than relying only on vegetation measurements.
Nest boxes are particularly useful where natural cavities are scarce. They provide enclosed nesting spaces that can partially compensate for limited availability of tree hollows or other suitable openings, helping support bird populations in altered habitats. Their value is greatest when considered alongside habitat restoration, because boxes address nesting-site availability while restoration can improve the surrounding ecological conditions.
Restoration can support cavity nesting birds by maintaining or increasing the habitat features associated with suitable nesting sites. Protecting mature trees and retaining dead or decaying wood can help preserve or create cavities, while nest boxes may provide additional sites where natural openings are limited. Together, these approaches can strengthen habitat structure and support biodiversity in managed or degraded environments.
