Elytra Reduction May Affect the Evolution of Beetle Hind Wings
Zoomorphology https://doi.org/10.1007/s00435-017-0388-1 ORIGINAL PAPER Elytra reduction may affect the evolution of beetle hind wings Jakub Goczał1 · Robert Rossa1 · Adam Tofilski2 Received: 21 July 2017 / Revised: 31 October 2017 / Accepted: 14 November 2017 © The Author(s) 2017. This article is an open access publication Abstract Beetles are one of the largest and most diverse groups of animals in the world. Conversion of forewings into hardened shields is perceived as a key adaptation that has greatly supported the evolutionary success of this taxa. Beetle elytra play an essential role: they minimize the influence of unfavorable external factors and protect insects against predators. Therefore, it is particularly interesting why some beetles have reduced their shields. This rare phenomenon is called brachelytry and its evolution and implications remain largely unexplored. In this paper, we focused on rare group of brachelytrous beetles with exposed hind wings. We have investigated whether the elytra loss in different beetle taxa is accompanied with the hind wing shape modification, and whether these changes are similar among unrelated beetle taxa. We found that hind wings shape differ markedly between related brachelytrous and macroelytrous beetles. Moreover, we revealed that modifications of hind wings have followed similar patterns and resulted in homoplasy in this trait among some unrelated groups of wing-exposed brachelytrous beetles. Our results suggest that elytra reduction may affect the evolution of beetle hind wings.

Host Plant Volatiles for Herbivores: a Bypass-Trophic Signal
Inhibition of Predator Attraction to Kairomones by Non- Host Plant Volatiles for Herbivores: A Bypass-Trophic Signal Qing-He Zhang¤, Fredrik Schlyter* Chemical Ecology, Department of Plant Protection Biology, Swedish University of Agricultural Sciences, Alnarp, Sweden Abstract Background: Insect predators and parasitoids exploit attractive chemical signals from lower trophic levels as kairomones to locate their herbivore prey and hosts. We hypothesized that specific chemical cues from prey non-hosts and non-habitats, which are not part of the trophic chain, are also recognized by predators and would inhibit attraction to the host/prey kairomone signals. To test our hypothesis, we studied the olfactory physiology and behavior of a predaceous beetle, Thanasimus formicarius (L.) (Coleoptera: Cleridae), in relation to specific angiosperm plant volatiles, which are non-host volatiles (NHV) for its conifer-feeding bark beetle prey. Methodology/Principal Findings: Olfactory detection in the clerid was confirmed by gas chromatography coupled to electroantennographic detection (GC-EAD) for a subset of NHV components. Among NHV, we identified two strongly antennally active molecules, 3-octanol and 1-octen-3-ol. We tested the potential inhibition of the combination of these two NHV on the walking and flight responses of the clerid to known kairomonal attractants such as synthetic mixtures of bark beetle (Ips spp.) aggregation pheromone components (cis-verbenol, ipsdienol, and E-myrcenol) combined with conifer (Picea and Pinus spp.) monoterpenes (a-pinene, terpinolene, and D3-carene). There was a strong inhibitory effect, both in the laboratory (effect size d = 23.2, walking bioassay) and in the field (d = 21.0, flight trapping). This is the first report of combining antennal detection (GC-EAD) and behavioral responses to identify semiochemical molecules that bypass the trophic system, signaling habitat information rather than food related information. -
Bugs & Beasties of the Western Rhodopes
Bugs and Beasties of the Western Rhodopes (a photoguide to some lesser-known species) by Chris Gibson and Judith Poyser [email protected] Yagodina At Honeyguide, we aim to help you experience the full range of wildlife in the places we visit. Generally we start with birds, flowers and butterflies, but we don’t ignore 'other invertebrates'. In the western Rhodopes they are just so abundant and diverse that they are one of the abiding features of the area. While simply experiencing this diversity is sufficient for some, as naturalists many of us want to know more, and in particular to be able to give names to what we see. Therein lies the problem: especially in eastern Europe, there are few books covering the invertebrates in any comprehensive way. Hence this photoguide – while in no way can this be considered an ‘eastern Chinery’, it at least provides a taster of the rich invertebrate fauna you may encounter, based on a couple of Honeyguide holidays we have led in the western Rhodopes during June. We stayed most of the time in a tight area around Yagodina, and almost anything we saw could reasonably be expected to be seen almost anywhere around there in the right habitat. Most of the photos were taken in 2014, with a few additional ones from 2012. While these creatures have found their way into the lists of the holiday reports, relatively few have been accompanied by photos. We have attempted to name the species depicted, using the available books and the vast resources of the internet, but in many cases it has not been possible to be definitive and the identifications should be treated as a ‘best fit’. -

How specificities evolve and new functions arise in related ORs within a species remain poorly investigated. We addressed this question by functionally characterizing ORs from the Eurasian spruce bark beetle Ips typographus, in which antennal detection and behavioral responses to pheromones, volatiles from host and non-host trees, and fungal symbionts are well described. -
Combining Multiple Statistical Methods to Evaluate the Performance of Process-Based Vegetation Models Across Three Forest Stands

In this contribution the performance of two global dynamic vegetation models, i.e. CARAIB and ISBACC, and one stand-scale forest model, i.e. 4C, was compared to long-term observed net ecosystem carbon exchange (NEE) time series from eddy covariance monitoring stations at three old-grown European beech (Fagus sylvatica L.) forest stands. Residual analysis, wavelet analysis and singular spectrum analysis were used beside conventional scalar statistical measures to assess model performance with the aim of defining future targets for model improvement. We found that the most important errors for all three models occurred at the edges of the observed NEE distribution and the model errors were correlated with environmental variables on a daily scale. -

Large grazing herbivores drive the ecology of the site and can have a profound impact on invertebrates, both positive and negative. This survey was commissioned in order to assess the site’s invertebrate assemblage in a standardised and repeatable way both internally between fields and sections and temporally between years. Eight fields were selected across the estate with two in the north, two in the central block -

Ekológia (Bratislava), Vol. 35, No. 4, p. 340–349, 2016. Communities of epigeic beetles were studied using pitfall trapping on 10 plots with the different stage of decline and clear-cut plots without coarse woody debris. Species richness (number of all species, S), total species diversity as the Shannon–Wiener’s index (H) and equitability (e) were calcu- lated in the DBreleve. The Ward’s method of hierarchical agglomerative classification with Euclidean distance was used for the differentiation of the communities on the plots. Species data for this analyse were represented by logarithm-transformed activities [log(x+1)]. The single-factor analysis of vari- ance (ANOVA) was used for statistical testing of differences in structural parameters (e.g. species richness and diversity) amongst distinguished groups of the plots. The species diversity and activity differs on glades without trees and coarse woody debris. -

Ekológia (Bratislava), Vol. 25, Supplement 3/2006, p. 41–52. The effect of tourism and various landscape management on the beetle communities were investigated using pitfall trapping in the montane area of the Central Europe (Šumava National Park and Landscape Protected Area). The pitfall traps were arranged on plots on the left and right side of the Lipno reservoir with the different anthropogenic pressure – the higher man pressure was traditionally on the left side of the Lipno reservoir. Beetle communities of the Norway spruce forest, ski trail, golf course, cultural meadow, parking plot, dam shore and the wetland were studied. The number of species discovered by pitfall trapping was lowest on the plots strongly affected by human activities (golf course and parking place). The skiing had no negative effect on epigeic beetles. Some species typical for open biotopes migrated to the ski trail and the forest species present at the edge of the forest and ski slope. -
