Territoriality has been observed to exist among certain animal species like birds, insects, mammals and vertebrates. Thus, exaggerated aggressive responses can be observed in both high- and low-arousal states, with different biochemical, neuroanatomical, and neuroendocrine systems contributing to behavior in each context. the territory (e.g. Indeed, organizational effects of gonadal hormones during adolescence have also been found for scent marking and territorial aggression in species as diverse as tree shrews, mice, and gerbils. Theo C.M. In adults, this flank marking behavior is essential for the maintenance of dominance relationships between males, and dominant males flank mark at higher levels than submissive males (Johnston, 1970; Ferris et al., 1987). Maynard Smith and Riechert (1984) developed a genetic model to explain the between-population differences noted at the time in territorial and agonistic behavior. Apparently, he was not yet acquainted with the informal rules about marking one’s space in the library. Analysis of dominance abilities was less straightforward because dominance had to be measured in contests between two individual males. Aggressive behavior is a motivated behavior. Children develop a feeling for property. Additional suggestions for helping an aggressive cat. https://www.petmd.com/dog/conditions/behavioral/c_dg_aggression_territorial In these ways similar behavioral patterns may be regulated by a conserved pathway by regulating diverse combinations of the components of that pathway. The genetic system is simply too complex and involves too many genes for linkage to be a likely cause. Instigation of a physical fight with a stranger who accidentally bumps into you is an example of reactive aggression. 3A and 3B; Bakker, 1986). What purpose, if any, does territoriality save for the human being in such a place like the library? There were clearly two peaks of territorial aggression, one in spring when breeding and the other in autumn, the nonbreeding life history stage. These data are consistent with the ‘hypersensitivity’ hypothesis. 3). Circulating steroid hormone precursors such as DHEA can be modulated with season being low during molt when territorial aggression was also at a nadir, and high in breeding and again in autumn when territorial aggression is elevated. Realized Heritabilities (h2) for Different Forms of Aggressivenessa. Early efforts to study aggression relied primarily on self-reports of aggression that estimated general aggressive tendencies. Neurotransmitters and neuromodulators in neuron networks involved in territorial aggression are probably also involved as in Figure 3. From Wingfield, J.C., 2012b. She found that stickleback, Genetic Correlations and the Control of Behavior, Exemplified by Aggressiveness in Sticklebacks, Selection for enhanced juvenile aggressiveness was less successful, producing significant divergence from the control line only in the second generation. A spider that showed a shorter latency to return to foraging following a predatory cue had a high probability of winning a territorial dispute against a spider that was equal in weight but had a longer latency to return to foraging. We have also established a link between the territorial behaviors and the attack and fear behaviors. Androgens (Bouissou, 1983) and estrogens (Laredo et al., 2014b) have important modulatory effects on intermale aggression, especially in territorial contexts. An important follow question in this scenario is how secretion of precursor steroids is regulated (Soma et al., 2008). Attacking or otherwise bullying your neighbors to intimidate them is another example of instrumental aggression. J. Ornithol. High levels of sex steroids in the peripheral blood would result in development of secondary sex characters inappropriate for the time year as well as other costs reviewed by Wingfield et al. Territorial displays may occur at windows, doors, behind fences and in the car. In subsequent encounters, there is little aggression per se, but the dominant–subordinate relationship is maintained through flank marking by both males, with the dominant male flank marking more frequently than the subordinate male. Huntingford (1976) hypothesized that territorial aggression and boldness toward predators shared some common factors(s) within the fish. Individuals maintain distinct distances between themselves and others. Then there's aggression on a much more sinister scale, in the form of murder, wars and genocide. 4), at which time males from the high dominance line dominated males from the low dominance line in 19 out of 24 dominance tests (χ2 = 8.17, P < 0.01; Bakker, 1986). Territorial behavior in cats usually involves urine marking (spraying), hissing, stalking, or attacking another cat. A first year male student arrived; he pushed aside my books and sat down to read. However, it's not appropriate for dogs living in a human society. Although the number of studies examined the effect of acute social defeat in females is small (Haller et al., 1999; Solomon, 2017), it has been shown that exposure to maternal aggression (Neumann, Toschi, Ohl, Torner, & Kromer, 2001) or to territorial aggression (Smith et al., 2013) can increase CORT and/or ACTH. Testosterone hypersensitivity hypothesis: It states that the brain nuclei associated with territorial aggression are more sensitive to circulating sex steroid hormones in autumn than in spring. Furthermore, implants of DHEA in autumn enhanced singing behavior and had morphological effects to increase song control regions such HVC (formerly known as the higher vocal center, now used as a proper name). Calhoun termed this phenomenon “pathological togetherness”. D. Professor of Sociology. This pattern of behavior, in which overt aggression is replaced by non-life-threatening flank marking, is an example of social proficiency or competence, defined as the ability of an animal to make adaptive changes in behavior as a result of social experience. Although the analogy cannot be applied to the library situation, nevertheless, territoriality in humans in the library could be to the advantage of the species. In the light of these genetic phenomena, Dobzhansky (1956) stated that “a trait has no adaptive significance in isolation from the whole pattern that the organism exhibits.” Huntingford provides a nice example of the need to consider the suite of behaviors rather than single traits. Here are three simple examples drawn from different (western) cultures Animal model studies in which testosterone has an important modulatory effect on aggression will be more informative for reactive aggression whereas approaches examining aggression under low-arousal conditions may be more informative for understanding instrumental aggression. Through studies and observations, the authors have come to the conclusion that the territorial behavior possesses several functions in the evolution and preservation of species. N., Pam M.S. This is called territorial aggression over humans. Figure 4. Why and how does testosterone affect parental and aggressive behaviors in some species and not in others? This behavioral insensitivity to circulating testosterone has been linked to high degree of paternal behavior (parental investment) in some species although much more investigation is needed to fully resolve the issue (Lynn, 2008; Lynn et al., 2005; Gerlach and Ketterson, 2016). There also may be linkage between loci that are closely positioned on the same chromosomes such that they segregate together. It is puzzling how complex the interrelationships of testosterone and aggression have become, but emerging diversity of mechanisms at cell and molecular levels, integration with behavioral ecology and evolutionary contexts may provide some commonalities yet (e.g., Hau et al., 2008; Hau and Goymann, 2015). 7, then the highly aggressive phenotype that results from crosses between the two populations is explained. (4) What are the internal signals that mediate aggressive behaviors? On deck 14 (psychology) 23rd December 1974, I sat down to read beside a female student. In contrast, high-profile incidents (e.g., mass killings, genocides, or assassinations) likely reflect instrumental mechanisms of aggression. This was confirmed in all the observations I made when the books are placed in this way, no other student can sit on the chair to read even if the owner of the “territory” goes away for a long time. From this observation, we can say that objects act as very strong definitions of territory for human beings. Prospectors stake c… Therefore, the only plausible explanation for man to display territoriality in places like the library, is that it is one of those behaviors which have lost their specific evolutionary functions and their remnants are perhaps in the process of degenerating into ritual behavior; i.e. First, the regulation of hormone secretion from the HPG axis, transport of testosterone by binding proteins in the blood (lines in red), and the mechanisms associated with the actions of testosterone in the target cell, in this case a neuron in the brain. The net result is regulation of territorial aggression including those neural networks regulated by arginine vasotocin, vasoactive intestinal peptide, and serotonin (see also Goodson et al., 2005, 2012; Wingfield et al., 2005). Given that many social behaviors change dramatically across the adolescent period, adolescent exposure to gonadal hormones may induce organizational change in a host of male social behaviors. Taken together, the data suggest profound shifts from circulating hormones of gonadal origin acting on behavior when breeding to central sources of steroids in the nonbreeding season (e.g., Heimovics et al., 2015b). Presumably, man feels uncomfortable having limited breathing and elbow movements, when they are too close together. Fig. Moreover, juvenile aggressiveness, male territorial aggressiveness, and male dominance ability were each significantly greater in laboratory-bred offspring from wild-caught parents originating from the population used in the selection study than they were in offspring from an allopatric Dutch population (Bakker, 1993a). Aggressiveness is expressed as the mean percentage of biting and bumping time against an opponent during weekly 5-min standardized aggression tests. This three-part system of control of hormone secretion, transport, and effects on target organs is an important concept because it proffers many points of potential regulatory mechanisms. It should also be pointed out that patterns of testosterone secretion and their actions on morphology, physiology, and behavior differ markedly between males and females. Table I. Trainor, ... R.J. Nelson, in Hormones, Brain and Behavior (Second Edition), 2009. Similarly, selection for reduced. Status only affected the number of flank marks in males that were gonad intact during adolescence and castrated and testosterone-replaced in adulthood, with dominant males flank marking significantly more than no-status and subordinate intact males (+ = p < 0.05).

Catherine A. Marler, in, Encyclopedia of Animal Behavior (Second Edition), Hormones, Brain and Behavior (Third Edition), ). The levels of aggression in the control line were in general rather constant, indicating limited environmental changes during the period of selection (Fig. The general definition of a territory is a “defended area”. In spotted antbirds in Panama, birds are territorial year-round in both breeding and nonbreeding seasons. Abnormal aggression has been characterized using quantitative or qualitative criteria (Natarajan and Caramaschi, 2010; Miczek et al., 2013). TERRITORIAL AGGRESSION. King (1975, 1976) and Peterson (1975) are recent examples of a long line of anthropologists If humans have evolved as aggressors, if using violence is a core part of our nature, then aggression needs to be a thing (a trait) that can be targeted and shaped by evolutionary processes. It has to be defended through actual aggression or the threat of it. There is evidence for some very low-level testosterone (T) secretion that maintains negative (-ve) feedback (blue lines), but territorial aggression, where it occurs in the nonbreeding season, can be expressed even in the absence of the gonads. Assumptions that testosterone secretion, secondary sex characters, and behavior covary in females as they do in males are likely false because selection pressures on males and females are different (Goymann and Wingfield, 2014). Students who read in the library regularly, at least every day, tend to have a specific chair and table where they read from every day. Aggressiveness in an unselected control line (C) is indicated in generations 0 and 2 (open circles). However, genes may influence many different characters, the manifold effects of a single gene being referred to as pleiotropism. “As in most vertebrates, we observe in man distinct territorial behavior. ACVB. Pharmacological inhibition of androgen and estrogen actions in captive males were less effective in decreasing territorial aggression in response to a challenge (Hau and Beebe, 2011) than in free-living males (Hau et al., 2004). Each one of them came, looked around and went away to another deck. Finally, we conclude from these studies that all four traits probably represent pleiotropic effects of the same genes, rather than linkage among chromosomes. The differences increased in the ensuing two generations (Figs. Fig. Pubertal testosterone programs context-appropriate agonistic behavior and associated neural activation patterns in male Syrian hamsters. Territorial aggression immediately conveys the reason behind the behavior and in that sense it is helpful. The outcome of any contest therefore depends on the phenotypes of both males. Specifically, males GDX before puberty and testosterone-replaced in adulthood display lower levels of flank marking overall, even if they are the dominant male. Another type of agonistic behavior commonly studied in the laboratory has been called fear-induced aggression, but this is more correctly termed defense. Thus, pubertal testosterone programs social proficiency, in addition to programming activation of flank marking (Figure 4). Thus an increase in plasma levels of DHEA from molt to autumn could result in more substrate for conversion to testosterone and/or E2 thereby activating autumnal territoriality. - April 29, 2013. the operation of defending a chosen space by provoking or threatening intruders of the same species. This nonsignificant trend was confirmed by the results of dominance tests between both dominance lines and the other selection lines in the third generation (see the following) suggesting that the divergence in the high and low dominance lines was due to a decrease in the dominance ability of males from the low dominance line rather than an increase in that of males from the high dominance line. By Nicholas Dodman, BVMS, Dipl. Increased arousal and anger are main components of what has been termed reactive aggression (Vitiello and Stoff, 1997), which is considered to be more impulsive yet can lead to sustained aggressive responses. The endocrine correlates of maternal aggression are vastly different from the endocrine correlates of, Haller and Kruk, 2006; Miczek et al., 2007a,b; Nelson and Trainor, 2007; Sluyter et al., 2003, Development of Hormone-Behavior Relationships, Given that many social behaviors change dramatically across the adolescent period, adolescent exposure to gonadal hormones may induce organizational change in a host of male social behaviors. These features are observable in many animal species including chimpanzees, to which human beings are genetically close. 2). During the first social encounter between two unfamiliar male hamsters in a neutral environment, an aggressive interaction initially occurs, and a dominant–subordinate relationship is typically established within a few minutes. These hypotheses are not mutually exclusive and some, or combinations, may be prevalent in different species at particular times in the life cycle suggesting that control of territoriality may have evolved numerous times in different contexts and life history stages – the evolutionary flexibility hypothesis (Hau, 2007; Hau and Wingfield, 2011). Furthermore, when prepubertally GDX males are reintroduced after the dominant–subordinate relationship was established in a prior encounter, they once again engage in overt aggression to reestablish the relationship, instead of maintaining the relationship via flank marking. There were no differences between no-status, subordinate, or dominant males that were gonadectomized (GDX) during adolescence and testosterone-replaced in adulthood prior to behavioral testing. Territorial aggression is a major component of social systems that fluctuates seasonally as well as within breeding seasons. By continuing you agree to the use of cookies. Comparing responses to STI across seasons showed that there was a resurgence of territorial aggression in spring and summer, but then aggression became very low during molt when males were nonresponsive to STI. In this respect perhaps ethical values of the individual subjects would come into question. (3) How does aggression develop across ontogeny? However, in other rodent species such as Syrian hamsters intrafemale aggression is more prevalent (Gutzler et al., 2010; Staffend and Meisel, 2012), which provides opportunities for examining neuroendocrine mechanism of female aggression outside of the context of reproduction. Territorial behaviour, in zoology, the methods by which an animal, or group of animals, protects its territory from incursions by others of its species. 2. Thus, from an ethological perspective, aggression is used for obtaining or defending food or mates from competitors; from a psychiatric perspective, aggression is thought to be motivated by hypothetical constructs, such as anger, irritation, frustration, fear, and, in some cases, pleasure (Blair et al., 2006). In a free-living tropical suboscine, the spotted antbird, Hylophylax naevioides, in Panama, mRNA for ERα in the preoptic area and AR in the nucleus taeniae were higher in males during the nonbreeding season when plasma levels of testosterone were lowest. This subtype of aggression can result in sudden, heightened, enduring, or inappropriate aggressive responses, and probably accounts for most societal problems that are associated with aggression (Blair et al., 2006). Thus, exaggerated aggressive responses can be observed in both high- and low-arousal states, with different biochemical, neuroanatomical, and neuroendocrine systems contributing to behavior in each context. Flank marking behavior is regulated in part by vasopressin V1a receptors in the lateral septum, and pubertal testosterone may organize the expression of V1a, as V1a receptor binding is significantly greater in prepubertally GDX males compared with males GDX in adulthood (Figure 3(b) and 3(c)). In tree shrews, prepubertal castration prevents testosterone from activating scent marking in adulthood (Eichmann and Holst, 1999). Selection for reduced juvenile aggressiveness produced significant divergence from the control line in both sexes after one generation of selection. With a hissing whisper, she asked one of the students whether he had moved the books. This is suggested by an experiment in overcrowding in which animals showed serious behavioral pathologies and physiological malfunctioning. There are some behavioral issues that pet parents can address themselves, but any problems that may present a danger to you, your dog, or other people typically require professional help.. This happens when the cat is aroused into an aggressive response by one person or animal, but then redirects this aggression onto another person or animal. Acute social defeat stress refers to a situation where an animal is exposed to a brief (1–15 min) territorial or maternal aggression from conspecifics. These types of aggression are most commonly studied in the laboratory and are tested by the so-called resident–intruder paradigm (see below). Territorial aggressive displays may range from growling and barking to lunging, chasing, snapping and biting. Bakker, in Advances in the Study of Behavior, 1994. In the second selected generation, males from the high dominance line won 5 out of 10 contests against control males, while males from the low dominance line won only 3 out of 10 contests. And a last function of territoriality is said to be reduction of aggression in the animal species which have a high level of it. Responses to three generations of selection (solid circles) for high and low levels of juvenile (JH and JL lines) and territorial (TH and TL lines) aggression. In males, acute social defeat as a result of, Kollack-Walker, Don, Watson, & Akil, 1999, Berton, Durand, Aguerre, Mormede, & Chaouloff, 1999, Neumann, Toschi, Ohl, Torner, & Kromer, 2001, Brian C. Trainor, ... Randy J. Nelson, in, Several categories of aggression are generally recognized, and the different types of aggression have different neuroendocrine bases. Intermale aggression and territorial aggression, as well as sex- and rank-related aggression, all appear to be mediated by androgens (Bouissou, 1983). The challenge hypothesis: behavioral ecology to neurogenomics. However, if cats start to show aggression towards humans then this would constitute ‘problem behaviour’. Among the social stressors, acute social defeat yields the highest CORT responses (Koolhaas et al., 2011). The size of that turf can range from a neighborhood, block, or yard to a home or a single room, she notes. Quantifying aggression in humans is a challenge. Two subtypes of human aggression have been proposed: (1) the controlled–instrumental subtype and (2) the reactive–impulsive subtype (Vitiello and Stoff, 1997). Behav., 50, 477–483. An interesting area of further examination in the library is the observation in animals that “Territories have been likened to elastic discs – the more they are compressed, the more they resist further compression.” (Manning; 1972, P. 99). 3C) and dominance ability (Fig. These are also features of human territoriality (although admittedly, few humans use scent to mark territorial boundaries). (3) How does aggression develop across ontogeny? It has to be defended through actual … Several categories of aggression are generally recognized, and the different types of aggression have different neuroendocrine bases. Because for most avian species this is the nonbreeding season, the hypothalamo–pituitary–gonadal (HPG) axis is essentially shut down as represented on the left-hand side of the figure in faded text. Natalia Duque-Wilckens, ... Catherine A. Marler, in Encyclopedia of Animal Behavior (Second Edition), 2019. The major characteristic of territoriality as observed by comparative psychologists like Lorenz, Tinbergen, and ethnologists like Eibl-Ebesfeldt, is that an animal must be aggressive towards conspecifics. An important follow-up question is then how to regulate enzyme expression in brain? Proposed directional dominance mechanism of inheritance of aggression and fear components of Agelenopsis aperta behavior. The controlled–instrumental subtype of aggression is thought to be regulated by higher cortical systems and less dependent on the hypothalamic and limbic systems that are known to mediate impulsive aggression (Viding et al., 2007; and see below), and likely less dependent on hormones than other types of aggression. 3C) because of some slight methodological differences between aggression tests in generation 0 and later generations (Bakker, 1986). Notably, the physiological regulation control of aggression in these contrived situations is likely to differ from the physiological mechanisms underlying natural expressions of aggressive behavior. The endocrine correlates of maternal aggression are vastly different from the endocrine correlates of territorial aggression. In this way, the major pathways regulating territorial aggression in the breeding and nonbreeding seasons may have similar or identical bases, but different points of the regulatory pathways are shut down or upregulated. (2) What neural circuitry mediates aggressive behaviors? Then I went to look for a book on the shelves. The response to three generations of selection for high (DH line) and low (DL line) dominance ability. Examples include mixed troops of monkeys, mixed-species flocks of birds, and fish schools in the tropics. Nongenomic activation of territorial aggression by estrogen given noninvasively (by injection into wax moth larvae that are then ingested by the birds) appears to be important in song sparrows in the nonbreeding season, but not in the breeding season (Heimovics et al., 2015a). Mental disorders such as intermittent explosive disorder and posttraumatic stress disorder are associated with increased autonomic arousal, which can contribute to sudden and uncontrolled reactive aggression (Blair et al., 2006; Viding et al., 2007). 'Territorial aggression' addresses a similar need, but on a much larger scale, and often occurs along boundaries of territory that the dog lives in, such as a yard or home. Territorial aggression often starts with threats and warning behaviors such as barking and it can eventually escalate to posturing, lunging and eventually biting. Managing the behavior by avoiding all circumstances that cause aggressive behavior is an appropriate solution if you are staying safe and your cat does not seem emotionally troubled. The net result is regulation of. This is not commonly directed at people. Similarly, selection for reduced territorial aggression produced significant divergence from the control line in reproductive males, but selection for enhanced aggression did not (Fig. Her books had been moved to the middle of the table where it was difficult to determine whether she had previously sat on one of the chairs. 3A) and females (Fig. In contrast, individuals who are diagnosed with conduct disorder or antisocial personality disorder show unusually low autonomic responsiveness (Viding et al., 2007), which can contribute to increased instrumental aggression by blunting the typical emotional responses (Raine, 2002). Copyright © 2021 Elsevier B.V. or its licensors or contributors. Abnormal aggression can be induced by very low glucocorticoid levels induced by adrenalectomy (Haller et al., 2001). B.C. Attacking or otherwise bullying your neighbors to intimidate them is an example of instrumental aggression. Susan E. Riechert, in Advances in the Study of Behavior, 1993. Following, this definition, yes territorial behaviour exists in humans. Error bars represent one standard error of the generation mean. Cats can bit… In autumn, after the molt was completed, territorial behavior increased (males became highly responsive to STI again), similar to territorial aggression in spring.
