In many territorial species androgen hormones are known to increase in response to territorial intrusions as a way to adjust the expression of androgen-dependent behaviour to social challenges. The dear enemy effect has also been described in territorial species and posits that resident individuals show a more aggressive response to intrusions by strangers than by other territorial neighbours. ...

This article brings together research on territoriality and actornetwork theory in order to develop new ways of investigating the role of materiality and material design in the territorial power relations of urban public places. Using the public square as a main example, I suggest some new ways of conceptualizing the production and stabilization of territories in the everyday urban environment....

We compared the field metabolic rate (FMR) and behavior around sugar-water feeders of sympatric territorial and non-territorial hummingbirds in the Chiricahua Mountains of southeastern Arizona during July 1987 and 1989. The territorial species was the Blue-throated Hummingbird (Lampornis clemenciae; mean mass 8.77 g) and the non-territorial species the Black-chinned Hummingbird (Archilochus ale...

Habitat use by the Little Blue Heron (Egretta caerulea) and discovery of feeding territoriality are discussed here. The results showed the existence of a territorial individual defending an area (2,564.46 +/- 943.56 m(2)) close to the mangrove, and non-territorial individuals (9.17 +/- 2.54) in the rest of a demarcated area (mean area for the non-territorial: 893.25 +/- 676.72). A weak positive...

Increasing localisation represents one of the most spectacular processes of the economies that develop and transform as a result of globalisation processes: while the (relative) importance of national economies is decreasing, the economic role of regions and cities seems to grow. Global competition has intensified also in space, especially with the growing importance of the knowledge-based econ...

BACKGROUND In the planning of selective internal radiation therapy (SIRT) for liver cancer treatment, one major aspect is to determine the prescribed activity and to estimate the resulting absorbed dose inside normal liver and tumor tissue. An optimized partition model for SIRT dosimetry based on arterial liver territories is proposed. This model is dedicated to characterize the variability of ...

We explore states’ decisions to escalate disputes over their territorial claims or settle them peacefully. We complement existing arguments by accounting for the fact that states are often simultaneously entangled in multiple territorial claims. We build on previous scholarship in positing that two states involved in a territorial dispute will act based on information they glean from each other...
