Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity. -

The interplay of landscape composition and 3 configuration: new pathways to manage functional biodiversity and agro-ecosystem services 4 across Europe. 5 6 Data preparation 7 Sites and landscapes 8 Raw data collected from researchers across Europe represented sampling and experiments for 9 144 arthropod families from 1960 sites in 10 countries and 29 regions in Europe. We defined 10 sites as belonging to the same study if they were measured by the same group of researchers, 11 using at least one identical method in all sites and years. According to country regulations, 12 land use maps were either directly collected from data holders, or a script was provided to 13 contributors to run calculations on locally held maps. Vector maps of land use were required 14 to be sufficiently detailed to detect boundaries between crop field polygons in order to enable 15 calculation of configuration measures (Fig. S1). As this is not the case of publicly available 16 land cover data, high quality maps compiled and partially ground-validated by study 17 participants were used. These maps were based on digitization of 1-2 m resolution 18 orthophotos and/or on official land use maps obtained from national or regional county 19 offices for each study. Minimum mapping units of the included maps, which allowed 20 boundary detection between crop fields, were 4*4 m (i.e., the smallest elements that were 21 mapped were ca. 4*4 m; see an example land use map in Fig. -

Native Insects on Non-Native Plants in the Netherlands: Curiosities Or Common Practice?
288 entomologische berichten 72 (6) 2012 Native insects on non-native plants in The Netherlands: curiosities or common practice? Kim Meijer Chris Smit Leo W. Beukeboom Menno Schilthuizen KEY WORDS Herbivorous insects, introduced plants, inventory, phytophagous insects Entomologische Berichten 72 (6): 288-293 In The Netherlands, close to 10% of all plant species occurring in natural habitats are non-native: species that were introduced from e.g. North America or Asia. Insect communities on non-native plants tend to get little attention from many (amateur) entomologists in The Netherlands for two main reasons. First, it is assumed that non-native plant species are not commonly used by herbivorous insects as host plants. Second, many entomologists consider insects associated with non-native plants of minor interest. Here, we give an overview of a large number (99) of native herbivorous insect species collected from non-native plant, clearly showing that non-native plants are used often as host plants. Introduction that species shifting to a novel environment (e.g., ecosystem or Non-native species can cause serious economic damage. In host) suffer less from natural enemies like predators, parasites, North America more than 50,000 species of plants, animals and herbivores and pathogens. Blossey & Nötzold (1995) suggested microbes have been introduced, causing an estimated $137 bil- the ‘Evolution of Increased Competitive Ability Hypothesis’ lion damage annually (Pimentel 2001). Furthermore, in many (EICA) as possible explanation of the success of non-native countries non-native species have a large effect on native spe- species. The EICA predicts that if plants escape from their her- cies and therefore also on the natural ecosystems in which bivores, they will allocate fewer resources to herbivore defence they occur. -

SEX-RELATED PERCEPTION of INSECT and PLANT VOLATILES in Lygocoris Pabulinus

EAGs were between 100 and 500 MV. Overall, male EAGs were about twice the size of female EAGs. In both sexes, largest EAGs were recorded to (E)-2-hexenyl butanoate and (E)-2-hexen-1-ol. Response profiles were similar in both sexes. However, male antennae were more sensitive to a number of esters, especially the butanoates and pentanoates. Female antennae were more sensitive to nine of the 19 plant volatiles, i.e., to hexan-1-ol, heptan-1-ol, 1-octen-3-ol, 2-heptanone, (R)-carvone, linalool, geraniol, nerol, and methyl salicylate. Sexual differences in responses suggest that males are more sensitive to insect-produced pheromone-type compounds, whereas females are more sensitive to plant compounds for their orientation towards oviposition sites.

Groot and J. Hans Visser Plant Research International, Wageningen University and Research Center, P.O. Box 16, 6700 AA Wageningen, The Netherlands Summary. Host plant volatiles may be involved in the Introduction sexual communication of insects in several ways. In the pheromone-producing sex, these volatiles may affect Host plant volatiles may be involved in the production, pheromone production or release and, in the receptive the release, or the perception of sex pheromones by sex, plant volatiles may have a synergistic effect on the insects (reviewed by McNeil & Delisle 1989; Landolt & attraction to sex pheromone. We conducted three types Philips 1997). Direct use of plant compounds as precur- of experiments to determine if and how plant volatiles sors for the biosynthesis of sex pheromone compounds are involved in the sexual communication of Lygocoris has been found mainly in male insects (Wood 1982; pabulinus (L.) (Heteroptera: Miridae), the females of Eisner & Meinwald 1987; Vanderwel & Oehlschlager which attract males. In a one-choice cylinder bioassay, 1987; Baker 1989; Landolt et al. 1992a). When females females were offered to males on two different plants, produce sex pheromone, plant volatiles have been belonging to different plant families, i.e. potato leaves found to initiate pheromone production in a more and goosefoot leaves, to determine if specific plant indirect way: females start producing pheromone when volatiles were involved in the attraction of males towards in the odor of a host plant (McNeil 1991; Raina et al. -
COI Barcoding of Plant Bugs (Insecta: Hemiptera: Miridae)
COI barcoding of plant bugs (Insecta: Hemiptera: Miridae) Junggon Kim and Sunghoon Jung Laboratory of Systematic Entomology, Department of Applied Biology, College of Agriculture and Life Sciences, Chungnam National University, Daejeon, Korea ABSTRACT The family Miridae is the most diverse and one of the most economically important groups in Heteroptera. However, identification of mirid species on the basis of morphology is difficult and time-consuming. In the present study, we evaluated the effectiveness of COI barcoding for 123 species of plant bugs in seven subfamilies. With the exception of three Apolygus species—A. lucorum, A. spinolae, and A. watajii (sub- family Mirinae)—each of the investigated species possessed a unique COI sequence. The average minimum interspecific genetic distance of congeners was approximately 37 times higher than the average maximum intraspecific genetic distance, indicating a significant barcoding gap. Despite having distinct morphological characters, A. lu- corum, A. spinolae, and A. watajii mixed and clustered together, suggesting taxonomic revision. Our findings indicate that COI barcoding represents a valuable identification tool for Miridae and can be economically viable in a variety of scientific research fields.
