A device was created to demonstrate electromyography-based control to a lay audience. After the success of the initial device, a second device was made with greater flexibility in functionality for demonstration and research purposes. This protocol describes the process of building and calibrating both devices.

Bone Markings

Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings. Articulating Projections Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Introducing multiple genomic alterations into cyanobacteria is an essential tool in the development of strains for industrial and basic research purposes. We describe a system for generating unmarked mutants in the model cyanobacterial species Synechocystis sp. PCC6803 and marked mutants in Synechococcus sp. PCC7002.
FAQs
A marking signal becomes informative when another animal can detect it and interpret it in relation to identity, territory, reproductive status, or social relationships. Its meaning therefore depends on both the signal itself and the environmental and social conditions surrounding it. The same broad marking function can be expressed through scent secretions, feces, urine, scratches, vocalizations, or visible displays.
Environmental and social conditions influence whether a cue can be detected and what information it conveys. A scent, scratch, vocalization, or display only affects behavior when other animals encounter it in a relevant context. Studying marking under these conditions helps biologists connect signals with territorial defense, mate selection, dominance, or coordination within animal groups.
These marking forms differ in how animals produce and detect information. Chemical cues can include scent secretions, feces, or urine; physical marks include scratches; auditory signals include vocalizations; and visual marks include visible displays. Together, they provide different routes for conveying information about identity, territory, reproductive status, or social relationships without reducing marking to a single communication mode.
Patterns of marking can indicate how animals defend space, select mates, establish dominance, or coordinate within groups. Researchers interpret marks alongside the social context in which they occur, rather than treating every cue as evidence of the same behavior. This approach connects observable signals with interactions among individuals and with broader biological processes shaping animal societies.
Researchers use marking behavior to assess population distribution and habitat use. Recording where marking occurs can help indicate how animals are distributed across environments and which areas they use. These observations are especially valuable in ecological and conservation research because they connect animal behavior with the spatial patterns needed to understand populations and their habitats.
Animal marking can provide evidence about species interactions and responses to environmental change. By examining marking in relation to habitats and other species, researchers can investigate how animals use space and interact biologically. Changes in marking patterns can also contribute to behavioral studies of how populations respond when environmental conditions shift.
