This Concept Map, created with IHMC CmapTools, has information related to: 7.1a Econ Defensibility of Terr, body fat being a measure of health and is positively correlated with the amount of time a male can sustain aerial contests with other males, shoulder patch size and vibrancy conveys information about the health of the male which is information a female uses when deciding with whom to mate, producing more offspring being the ability to use the resources on a territory without interference from others, energy expended defending a territory with the possibility of injury or death to the territory owner, exposure to predators while defending a territory with the possibility of injury or death to the territory owner, Males of the Damselfy Species in which males that have lower body fat are "floaters", 7.1a Economic Defensibility of Territoriality when Costs of Territoriality outweigh Benefits of Terriroriality, animals may live together, not defending individual territories for example male Yarrow's Spiny Lizard, the "non-breeding season" but during the breeding season will change tactics and become territorial, males that have more body fat are territory holders with body fat being a measure of health, males that have lower body fat are "floaters" with body fat being a measure of health, Costs of Territoriality outweigh Benefits of Terriroriality the animal may adopt a "floater" strategy (pp.206-207), The Red-Shouldered Widowbird in which males with brighter, larger shoulder patches are territory holders, A male bird without its own territory or mate, moves around ("floats" furtively) to find opportunities for both. for example The Red-Shouldered Widowbird, young male collared lizards that acquire a territory upon the death of an older territory holder have more opportunities to court females than males who are unable to secure a territory For example, the ability to use the resources on a territory without interference from others, Benefits of defending a territoriy being the ability to use the resources on a territory without interference from others, males with brighter, larger shoulder patches are territory holders suggesting shoulder patch size and vibrancy conveys information about the health of the male, A male bird without its own territory or mate, moves around ("floats" furtively) to find opportunities for both. for example Males of the Damselfy Species, the trade-off in costs versus benefits for maintaining a territory with the Benefits of defending a territoriy, Males of the Damselfy Species in which males that have more body fat are territory holders
