and New Zealand attended the meeting (see the list of participants and the group photo in Fig. 1). The attendance has increased since the fi rst meeting took place in 2006. More than 40% of the participants attended the meeting for the fi rst time, and we were again pleased to host not only the established scientists in beetle systematics but also many students. Eighteen oral lectures and one poster were presented, covering a wide spectrum of topics concerning nearly all major clades of beetles (Adephaga, Hydrophiloidea, Staphylinoidea, Scarabaeoidea, Byrrhoidea, Buprestoidea, Elateroidea, Chrysomeloidea and Curculionoidea). The contributions embraced many interesting topics such as unusual adaptation of immature beetles in environments like caves and bromeliad plants, DNA barcoding and its role in ecological and faunistic monitoring, as well as biographic memories of the life and work of the great immature-beetle pioneer, Fritz Isidore van Emden. After the presentations were fi nished, an optional visit to the Coleoptera collection of the National Museum took place, and was enjoyed by the colleagues who joined. As it became a tradition for the Immature Beetles Meeting, the discussion about beetle topics continued in a traditional Czech pub on both evenings. We hope that the meeting again fulfi lled its main goal-to bring together people with an interest in the immature stages of Coleoptera, and to help specialists to estabilish and maintain contacts and cooperation with colleagues across countries and generations. In keeping with the spirit of providing a platform for coleopterists interested in the immature stages, the organizing team of the Immature Beetles Meeting is presenting a new web page. Besides helping to promote the meeting itself, it is intended to be a virtual meeting point for specialists worldwide where their profi les including their publications lists will be available, together with other news regarding the world of beetle larvae.

Abstracts of the Immature Beetles Meeting 2015, October 1−2, Prague, Czech Republic
2015
Two years after the last get-together and following the biennial tradition, the sixth Immature Beetles Meeting was held in Prague on October 1–2, 2015. Similarly as two years ago, it took place at the Faculty of Science of the Charles University in Prague and was organized in the cooperation with the Department of Entomology of the National Museum and the Crop Research Institute in Prague. In total, 55 participants from Europe, North and South America and Asia attended the meeting (Fig. 1), including a large Brazilian delegation comprising students and scientists from three different universities. Nearly half of the participants attended the meeting for the first time, and we were again pleased to host not only the leading experts in beetle systematics (e.g., Pawel Jaloszynski, Jolanta Świetojanska, Josef Jelinek, Eugenio Nears, Nathan Lord and others), but also many pregraduate students. Seventeen oral lectures and two posters were presented, covering a wide spectrum of topics conc...
Sampling saproxylic beetles: lessons from a 10-year monitoring study
Biological Conservation, 2004
We sampled saproxylic beetles using trunk window traps in two birch-dominated forests in Finland during 1990Finland during -1999. The sampling scheme, 10 traps attached to living fruiting bodies of Fomes fomentarius growing on dead birches, remained unchanged in both forests throughout the study period. Beetles belonging to 32 selected families were identified every year, whereas all species were identified during the last 4 years. Total number of identified individuals was 40,294 and number of species 583, of which 258 were saproxylic (dependent on dead wood). Species richness of rare and threatened saproxylic beetles in the samples varied a lot between the years and did not fluctuate synchronously between the forests. Variation between years was smaller when all saproxylic species were pooled together and some abundant species fluctuated synchronously in the two forests. Similarity indices and DCAordination did not generally suggest decreasing similarity between samples with increasing temporal isolation. Incidence-based similarities of common saproxylic species within and between forests and years were high (means 0.7-0.8), whereas those of rare saproxylics were roughly 50% smaller and much more variable. More than 75% of the common saproxylic species found during the entire 10-year period were detected already after 3 years of sampling but accumulation of rare and threatened species was much slower. Our results suggest that: (1) occurrence of rare and threatened species in samples is much less predictable than that of common species and, e.g. reserve selection based on rarities should be made cautiously; (2) estimation of total number of threatened species in a forest is very difficult, because such species accumulate slowly in the samples; (3) samples from different years can be comparable in certain cases.
Biodiversity and Conservation, 1998
A survey of forest litter-inhabiting Coleoptera was conducted in deciduous forests of the Ouachita Mountains in western Arkansas during 1991±1992. A total of 102 Berlese samples were collected, weighed, and processed during the 12-month study. From 741 kg of sifted forest litter, we counted and sorted 10 663 adult beetles representing 46 families and 400 species. The family Staphylinidae was taxonomically and numerically dominant, comprising 46% of species and 63% of individuals. Problems in assessing species richness of forest litter Coleoptera faunas result from a lack of taxonomic revisions, occurrence of sex-limited diagnostic characters, and inadequate information about larval-adult species associations and life histories. A randomized species accumulation curve indicated that species addition ranged from 14 species per sample during the ®rst ten samples to 1.5 species per sample during the ®nal ten. Richness estimates generated from the empirical data ranged from 434 species (Michaelis±Menten and Coleman richness estimators) to 590 species (second order jacknife). The area sampled is biogeographically signi®cant because it harbors numerous habitatrestricted species that are endemic to the Ouachita Mountains or the Interior Highland region, as well as disjunct populations of species that are also found in the southern Appalachian Mountains. Deciduous forest habitats of the Ouachita Mountains, particularly beech-maple riparian forest, should be given special consideration in forest conservation planning because of their signi®cance as refugia for these and other endemic and disjunct arthropods.
Beetle assemblages from the Warra log-decay project: insights from the first year of sampling
2003
The Warra log-decay project is a long-term study of biodiversity in decaying logs of two age classes ('oldgrowth' and 'regrowth'), aimed at developing a better understanding of the ecology of coarse woody debris (CWD) and its biodiversity in Tasmanian wet eucalypt forests. Analyses of the first year's data demonstrate the existence of a rich saproxylic beetle fauna, so far amounting
The state of Arizona in the southwestern United States supports a high diversity of insects. Digitized occurrence records, especially from preserved specimens in natural history collections, are an important and growing resource to understand biodiversity and biogeography. Underlying bias in how insects are collected and what that means for interpreting patterns of insect diversity is largely untested. To explore the effects of insect collecting bias in Arizona, the state was regionalized into specific areas. First, the entire state was divided into broad biogeographic areas by ecoregion. Second, the 81 tallest mountain ranges were mapped onto the state. The distribution of digitized records across these areas were then examined. A case study of surveying the beetles (Insecta, Coleoptera) of the Sand Tank Mountains is presented. The Sand Tanks are low-elevation range in the Lower Colorado River Basin subregion of the Sonoran Desert from which a single beetle record was published bef...
The beetles at Wog Wog: a contribution of Coleoptera systematics to an ecological field experiment
Invertebrate Systematics
In this brief review we outline the contribution of Dr J. F. Lawrence to a major long-term field experiment in the southeast forests of NSW that examines the effect of habitat fragmentation on beetles. Dr J. F. Lawrence identified and curated the beetle fauna, which proved to be a significant and long-term commitment. The beetle data set has since provided great insight to the complex effects of habitat fragmentation. In addition, the size and quality of the data set mean that, on an international level, it is a major inventory of beetle diversity in a temperate Eucalyptus forest, in its own right. Here we outline Dr J. F. Lawrence’s contribution and summarise the main features of the beetle data set and our findings about the impacts of fragmentation on the beetle fauna.
Beetles (Coleoptera) are a charismatic group of insects targeted by collectors and often used in biodiversity surveys. As part of a larger project, we surveyed a small (4 hectare) plot in the Boston Mountains of Arkansas using 70 traps of 12 trap types and Berlese–Tullgren extraction of leaf litter and identified all Buprestidae, Carabidae, Cerambycidae, and Curculionoidea (Anthribidae, Attelabidae, Brachyceridae, Brentidae, and Curculionidae excluding Scolytinae) to species. This resulted in the collection of 7,973 specimens representing 242 species arranged in 8 families. In a previous publication, we reported new state records and the number of specimens collected per species. In this publication, we used these data to determine the most effective collection method for four beetle groups: Carabidae, Cerambycidae, Curculionoidea (excluding Scolytinae), and Buprestidae. We found that the combination of pitfall and Malaise traps was most effective for Carabidae, Cerambycidae, and Curculionoidea, but that the combination of Malaise and green Lindgren funnel traps was most effective at collecting Buprestidae. Species accumulation curves did not become asymptotic and extrapolated rarefaction curves did not become asymptotic until 350–1,000 samples, suggesting that much more effort is required to completely inventory even a small site. Additionally, seasonal activity is presented for each species and the similarity and overlap between collecting dates and seasons is discussed for each family.
