Where animals sleep may be an important component of their behavioral ecology, as sleeping renders animals immobile and hypothetically vulnerable for long periods. Yet, sleep is rarely studied outside of the laboratory. To investigate factors that influence natural sleeping behavior, we examined sleeping locations of three sympatric species of territorial Anolis lizards (Anolis lineatopus, A. g...

In fish species with alternative male mating tactics, sperm competition typically occurs when small males that are unsuccessful in direct contests steal fertilization opportunities from large dominant males. In the grass goby Zosterisessor ophiocephalus, large territorial males defend and court females from nest sites, while small sneaker males obtain matings by sneaking into nests. Parentage a...

Is the demarcation problem dead, or are the rumors of its demise greatly exaggerated? ! e answer depends on whom you ask. Some philosophers of science have voiced the opinion that the demarcation project has been something of an embarrassment to their discipline and that terms like “pseudoscience” and “nonscience” should be erased from our philosophical vocabulary, wedded as they are to a naïve...

In many social animals, group-mates cooperate to defend their range against intrusion by neighboring groups. Because group size tends to be highly variable, such conflicts are often asymmetric. Although numerical superiority is assumed to provide a competitive advantage, small groups can generally defend their ranges, even when greatly outnumbered. The prevailing explanation for this puzzling p...

How does the history of a nation’s relation to transgender subjects affect their situated imaginings national territorial borders, collectivity boundaries and gender barriers? This article offers an answer this question through close reading photographs by artist Yael Meiry. Based on visual culture analysis Meiry’s intervention in dominant Zionist historical narrative I argue that using photogr...

Testosterone produced by the gonads is a primary mediator of seasonal patterns of territoriality and may directly facilitate territorial behavior during an encounter with a potential intruder. Costs and benefits associated with territoriality can vary as a function of habitat, for example through differences in resource distribution between areas occupied by different individuals. We investigat...

Chemical structures of several urinary reproductive pheromones in fish have been identified, and their role in the chemical communication of reproductive condition is well characterized. On the contrary, the role of chemical communication in signalling of social/territorial status in fish is poorly understood. Fathead minnows are an example of a fish species whose life history traits appear con...

Theory predicts the evolution of alternative male social tactics when intense competition coupled with the superior competitive ability of some individuals limits access to reproductive opportunities by others. How selection has shaped alternative social tactics may be especially interesting in long-lived species where size among sexually mature males varies markedly. We conducted experimental ...

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....
