Abstract: Structural and functional traits of organisms are known to be related to the size of individuals and to the size of their colonies when they belong to one. Among such traits, propensity to inquilinism in termites is known to relate positively to colony size. Larger termitaria hold larger diversity of facultative inquilines than smaller nests, whereas obligate inquilines seem unable to settle in nests smaller than a threshold volume. Respective underlying mechanisms, however, remain hypothetical. Here we test o… Show more

“…Further, patroller duration increased superlinearly with patroller number, so that patrols with more soldiers lasted disproportionately longer, in agreement with the higher patrolling rates of smaller trees. This result parallels the allometric decay of patrolling rate with colony size reported by a recent study on another nasute termite species, Constrictotermes cyphergaster (DeSouza et al., ). Higher patrolling rates in smaller trees could reflect higher per capita metabolic rates and activity levels of smaller colonies (Waters, ), shorter travelling distances, or a combination thereof.…”

“…Patroller number, patrol duration, and patrolling rate were used as dependent variables in separate analyses in order to determine their response to tree size (a proxy for colony size), as well as the effect of experimental manipulations on this response. Size dependencies typically conform to power laws of the form y = a × x b (DeSouza et al., ; Waters, ). This function can be linearized by taking logs of both sides, that is, log( y ) = log( a ) + b × log( x ).…”

“…Interactions between fire and nest volume are also bound to happen because immigration should be favored in larger as opposed to smaller nests because, in these latter, soldiers exert higher patrolling rates (DeSouza et al., ). Also, invaders are prone to be more successful in larger nests where space availability alleviates the rate and consequent harmful effects of interspecific encounters, particularly with termitophilous ants (Higashi & Ito, ).…”

“…The respectable amount of knowledge thereby produced allowed, as a natural step forward, that the determinants of intruders’ success at the scale of the nest entered termitophily's research agenda (Cristaldo, Rosa, Florencio, Marins, & DeSouza, ; Leponce, Roisin, & Pasteels, ). We are now starting to perceive that intruders’ success in termitaria depends not only on interindividual interactions but also on factors operating at broader levels, viz., the nest or a set of nests (DeSouza et al., ; Marins et al., ). Adding this new focus to studies on termitophily is highly desirable, given the meaning of spatial scale on the colonization dynamics of patchy/insular environments, among which termitaria seem to fit quite well.…”
