Such consumers also often seem to show consistent differences in the rates of evolution of these two dimensions of host use, implying common processes, but this has been little studied. Here we quantify these rates of change in host use evolution in a major radiation of herbivorous insects, the Chrysomeloidea, whose diversity has been attributed to their use of flowering plants. We find a significant difference in the rates of evolutionary change in these two dimensions of host use, with host taxon associations most labile. There are apparently similar differences in rates of host use evolution in other parasite groups, suggesting the generality of this pattern. Divergences in parasite form associated with use of different host tissues may facilitate resource partitioning among successive adaptive radiations on particular host taxa.10aBruchidae10aCerambycidae10aChrysomelidae10aherbivory10ainsect-plant interactions10aparasite-host interactions10aphylogeny1 aFarrell, Brian, D.1 aSequeira, Andrea, S.  uhttps://cephaloleia.myspecies.info/node/2701976nas a2200133   4500008004100000245009800041210006900139300001200208490000700220520141100227653013701638100002001775856004701795       2004                        eng d00aLife history and demography of Cephaloleia fenestrata (Hispinae : Chrysomelidae : Coleoptera)0 aLife history and demography of Cephaloleia fenestrata Hispinae C  a352-3610 v363 aThe Neotropical beetle Cephaloleia fenestrata is a specialist herbivore on Pleiostachya pruinosa (Marantaceae) in upland and flood zone habitat of lowland tropical wet forest in Costa Rica. Cephaloleia fenestrata spends its entire life cycle on P pruinosa, feeding primarily in rolled young leaves as adults, feeding in the concavity of leaf petioles as larvae, and laying eggs and pupating on the leaf petioles. Egg development time is about average for Chrysomelidae, approximately ten days. Cephaloleia fenestrata larvae, like other rolled leaf hispines, have an extremely long development period (94 d) consisting of only two instars (compared to a range of three to six in other Chrysomelidae). The 30-day pupal stage is also long, but within the range of that observed in other Chrysomelidae. Adults live an average of six weeks. The generation time for C fenestrata is thus approximately six months. Male C fenestrata lived longer and had a higher capture probability than females. There was no difference between males and females in the movement probabilities between upland and flood zone habitat. Rolled P pruinosa leaves are both ephemeral (available to the beetles for approximately two days) and somewhat rare (I in ca 15 ramets has a rolled leaf). Adults must move from leaf to leaf ca 36 times during their average adult life span. Still, C fenestrata adults demonstrate high site fidelity.10acephaloleia fenestrata chrysomelidae hispinae marantaceae mark-recapture pleiostachya pruinosa heliconia beetles zingiberales plants1 aJohnson, D., M.  uhttps://cephaloleia.myspecies.info/node/2802593nas a2200133   4500008004100000245006800041210006600109300001400175490000700189520195100196653024502147100002002392856004702412       2004                        eng d00aSource-sink dynamics in a temporally, heterogeneous environment0 aSourcesink dynamics in a temporally heterogeneous environment  a2037-20450 v853 aIn traditional source-sink models, vital rates and movement probabilities are assumed to be temporally homogeneous. Numerous studies, however, have demonstrated that temporal heterogeneity is the rule rather than the exception in natural systems. A case of particular interest is an expanding and contracting population where determination. of source and sink populations is dependent on the timing and duration at which population growth rates are measured. Thus, ecologists have been perplexed about what is the proper scale to test for source-sink dynamics. In this study, I present a temporally variable source-sink dynamic driven by flooding disturbance. I measured population growth rates of an herbivorous neotropical rolled-leaf beetle, Cephaloleia fenestrata (Chrysomelidae), at different temporal scales in this expanding and contracting population. I demonstrate that flooding created a strong sink, but the system lacked source-sink dynamics during nonflood periods. The sink is caused by a flood-related sevenfold decrease in survival probability. There was no evidence for effects of flooding on recruitment. Migration was directional from the upland to the flood zone habitat, supporting the conclusion that the population in the flood zone is a sink. A Monte Carlo simulation demonstrated that whether the population in the flood zone is a sink, and the intensity of the sink, ultimately depend on the flooding frequency. Given an observed flood frequency of approximately once per year, the flood zone population was determined to be a Ion g-term sink. This study provides evidence of high temporal variability resulting in fluctuations in and out of a source-sink dynamic and implicates a causal factor (increased mortality due to flooding). These results illustrate the importance of. considering temporal variability in source-sink dynamics, and in choosing the proper temporal scale at which to test for source-sink dynamics.10acephaloleia fenestrata dispersal disturbance flooding mark-recapture pleiostachya pruinosa source-sink. dynamics survival temporal heterogeneity population-dynamics empirical-evidence quality metapopulation dispersal habitats forests models1 aJohnson, D., M.  uhttps://cephaloleia.myspecies.info/node/29
