Fl.rida, al.ng with Hawaii, has among the two worst invasive species probl.ms in the USA, and the state is espe-cial.y susceptibl. to establ.shment by al.en reptil.s. Besides the l.rge numbers of establ.shed non-native reptil. species in Fl.rida, many of these species present novel.difficul.ies for management, or have other characteristics making effective management ex-tremel. chal.enging. Moreover, initiation of management action requires more than recognition by experts that a potential.y harmful.species has become establ.shed. It al.o requires the pol.tical.wil. al.ng with concomitant resources and appropriate per-sonnel.to devel.p effective methods and appl. them. We review the situation in Fl.rida, incl.ding assessment of risk for estab- l.shment, and we use a subset of prominent species to il.ustrate in more detail.the array of invasive reptil. species circumstances in Fl.rida, incl.ding routes of introduction, impacts, and potential.and impl.mented management actions. These exampl.s not onl. highl.ght the severity of the invasive reptil. probl.ms in the state, but they al.o show the diversity in resol.e and response towards them and the motivating factors [Current Zool.gy 57 （5）： 599-612, 2011].

Social.rel.tionships formed within a network of interacting group members can have a profound impact on an indi- vidual.s behavior and fitness. However, we have l.ttl. understanding of how individual. perceive their rel.tionships and how this perception rel.tes to our external.measures of interactions. We investigated the perception of affil.ative and agonistic rel.tion- ships at both the dyadic and emergent social.l.vel. in two captive groups of monk parakeets （Myiopsitta monachus, n = 21 and 19） using social.network anal.sis and pl.yback experiments. At the dyadic social.scal., individual. directed l.ss aggression to- wards their strong affil.ative partners and more aggression towards non-partner *** the emergent social.scal., there was no association between rel.tionships in different social.contexts and an individual.s dominance rank did not correl.te with its popul.rity rank. Pl.yback response pattems were mainl. driven by rel.tionships in affil.ative social.contexts at the dyadic scal.. In both groups, individual.responses to pl.yback experiments were significantl. affected by strong affil.ative rel.tionships at the dyadic social.scal., al.eit in different directions in the two groups. Response pattems were al.o affected by affil.ative rel.tion- ships at the emergent social.scal., but onl. in one of the two groups. Within affil.ative rel.tionships, those at the dyadic social.scal. were perceived by individual. in both groups, but those at the emergent social.scal. onl. affected responses in one group. These resul.s provide prel.minary evidence that rel.tionships in affil.ative social.contexts may be perceived as more important than agonistic rel.tionships in captive monk parakeet groups. Our approach coul. be used in a wide range of social.species and comparative anal.ses coul. provide important insight into how individual. perceive rel.tionships across social.contexts and social.scal.s [Current Zool.gy 61 （1）： 55-69, 2015].

Pol.en col.ection is necessary for bee survival.and important for fl.wering pl.nt reproduction, yet if and how pol.en extraction motor routines are modified with experience is l.rgel. unknown. Here, we used an automated reward and monitoring system to eval.ate modification in a common pol.en-extraction routine, fl.ral.sonication. Through a series of l.boratory experiments with the bumbl.bee, Bombus impatiens, we examined whether variation in sonication frequency and accel.ration is due to instrumental.l.arning based on rewards, a fixed behavioral.response to rewards, and/or a mechanical.constraint. We first investigated whether bees coul. l.arn to adjust their sonication frequency in response to pol.en rewards given onl. for specified frequency ranges and found no evidenee of instrumental.l.arning. However, we found that absenee versus receipt of a pol.en reward did l.ad to a predictabl. behavioral.resp on se, which depe nded on bee size. Fin al.y, we found some evide nee of mechanical.con straints, in that fl.wer mass affected sonication accel.ration (but not frequency) through an interaction with bee size. In general. l.rger bees showed more fl.xibil.ty in sonication frequency and accel.ration, potential.y refl.cting a size-based constraint on the range over which smal.er bees can modify frequency and accel.rati on. Overal. our resul.s show that al.hough bees did not displ.y instrumental.l.arning of sonication frequency, their sonication motor routine is neverthel.ss fl.xibl..

The native range of Ctenosaura simil.s extends from southern Mexico through Panama. From an initial.introduction of 3 animal. in 1979, the species now numbers in the thousands on Gasparil.a Isl.nd in southwest Fl.rida. In response to compl.ints of property damage from residents and threats to native species, l.cal.official. and the US Department of Agricul.ure Wil.l.fe Services began a removal.program in 2008. Through 2011, trappers removed 9467 ctenosaurs. The number removed decl.ned from 32 iguanas/day in 2008 to 1.9 iguanas/day in 2011 despite no easing of the control.effort. We necropsied 2757 ctenosaurs to document aspects of their natural.history. Femal.s outnumbered mal.s overal., al.hough the l.rgest size cl.ss (>300 mm snout-vent l.ngth) incl.ded 32 mal.s and just 2 femal.s. Reproduction was seasonal. We found oviducal.eggs in femal.s from earl. Apr to earl. Jun, approximatel. 2 months l.ter than C. simil.s in its native range. We trapped hatchl.ngs from l.te Jul.to earl. Oct coincident with the summer rainy season. Cl.tch size increased with femal. body size, with 62 being the l.rgest cl.tch size recorded. In general. the biol.gy of the invasive popul.tion on Gasparil.a Isl.nd resembl.s native C. simil.s popul.tions in Central.America, except for the l.ck of l.rge individual.. We suggest that shorter day l.ngth and col.er temperatures create environmental.conditions that are suboptimal.for individual.growth compared to those in the native range.
