	abstract = {Plasticity of various life-history traits has evoked continuing interest among biologists. For example, the plasticity of offspring characteristics as well as maternal effects may be affected by time limitation and by limitation caused by changing environmental conditions. However, it is difficult to tell apart the effect of a time constraint, experienced by the mother, from food limitation, which is experienced by the offspring at the end of the season. In this study, we controlled for food limitation and simulated a time constraint for the mother. We tested how the seed beetle, Coccotrypes dactyliperda, adapts its reproductive investment after encountering a period of low availability of seeds as oviposition sites, as compared with females that encountered a seed at an early adult stage, while maintaining a similar food supply for offspring of both groups. We show that time limitation has a significant effect on the reproductive investment patterns of females. Females that were prevented from ovipositing, but provided with abundant food and later given oviposition sites, produced more, but smaller offspring than control females. Although the number of offspring increased, there was no indication of competition for food between offspring. We propose that, in order to compensate for the loss of time, mothers that experienced a shortage of oviposition sites influence their offspring to mature faster at the cost of a smaller than average body size. This study emphasizes the importance of considering more than one offspring generation in order to correctly estimate female fitness.},

	abstract = {Hypothenemus hampei is the most important insect pest of coffee and has spread to most coffee-growing countries worldwide. There have been very few studies and none have addressed the population genetics of the beetle using microsatellite markers. In the present study, 683 individuals collected from 37 locations in 18 countries worldwide were screened at nine polymorphic microsatellite loci. Sixty-five out the 683 and six additional individuals were analyzed on a 400-bp fragment of the mitochondrial cytochrome oxidase I gene. Bayesian clustering analysis and phylogenetic approaches were used to infer the genetic structure of H. hampei over the sampling that encompassed almost all its range. Microsatellite markers made it possible to achieve sufficiently significant power for the delineation of five morphocryptic evolutionary units. Supported by 27 new COI haplotypes, an unexpected considerably high level of genetic differentiation and genetic divergence was revealed between five geographically delineated clusters. Both markers and approaches showed that the clusters included specimens from (1) Ethiopia, (2) Kenya and Uganda, (3) Brazil, (4) Central America excluding Jamaica, and (5) all samples from Asia, West Africa, and Jamaica. These findings clearly suggest the existence of a {\textquoteright}species complex in H. hampei{\textquoteright}.

	abstract = {Differentiation among the European populations of the six-toothed spruce bark beetle Pityogenes chalcographus was observed for the first time in the 1970s as mating males from Northern Europe with females from Central Europe led to a significant decline in fecundity. Morphological examination revealed that P. chalcographus can be separated into two European races. Here, we investigated the genetic background of this separation by analysing 39 populations (n = 695), sequencing almost the complete cytochrome oxidase I gene (1543 bp) and applying single-strand conformation polymorphism. Phylogenetic analysis of 58 haplotypes yielded three major clades with a maximum sequence divergence of 2.33\%, indicating that the demographic events took place in the late Pleistocene. These results support the hypothesis of allopatric divergence of the mtDNA lineages, which postglacially came into sympatric existence in Europe. However, as a result of partial crossing incompatibility the diverged lineages retained their genetic identity during postglacial times.},

	abstract = {Rapa Island in SE Polynesia hosts a remarkable adaptive radiation of small, flightless weevils in the genus Miocalles. Sixty-seven species are known at present, of which 26 are described as new. One new name, two new combinations, and two new synonyms are established. The paradoxical occurrence of a large adaptive radiation on a small (40 km2), isolated, oceanic island is analysed in its evolutionary and ecological aspects: how did so many species of weevils evolve, and how is such a diversity of weevils maintained? Most of the speciation has taken place on Rapa itself. Two principal methods of intra-island isolation of weevil populations have led to speciation: between high mountain ranges, and between Rapa and its satellite islets. Glacial sea level fluctuations aided in speciation by connecting the satellite islets to Rapa at times, and by the downward extension, and connection of high-altitude cloud forests. Some speciational events may have taken place in 15000-150000 years. Close relatives of Rapan weevils are known from nearby Marotiri, an almost sunken island, and from the neighbouring Austral archipelago, with which some inter-island speciation has taken place. The weevil species are almost all host-plant specific. There are often several species occupying the same host plant, in which case they may inhabit different parts of it. Some plants with a longer history on Rapa host more weevil species than newer arrivals.},
