Aim The future of biodiversity in increasingly warmer mountains may be poorly predicted by climate variation if dispersal affects ecological change. We assessed the influence limitations assembly mountaintop communities, focusing on relationship between proxies flight abilities and species diversity insects. Location Cantabrian Mountains, Spain. Taxon Grasshoppers (Orthoptera, Acrididae) bumble...

Abstract Stink bug (Hemiptera: Pentatomidae) development typically requires feeding on a diversity of plant species and various tissues. During feeding, stink bugs discharge salivary enzymes with roles in extraoral digestion countering defense responses. Although previous research has described digestive proteins from bugs, less is known the involved suppression defenses. We sequenced transcrip...

– The Upland Sandpiper (Bartramia longicauda) is a migratory shorebird that inhabits grasslands at the breeding and non-breeding grounds. The trophic ecology of the species is poorly known, but it is thought to be insectivorous. In this study, we describe the diet of the Upland Sandpiper and its temporal variation in grasslands of northern Uruguay. From 2008 to 2012, we collected 67 feces at ni...

Food availability and acquisition are critical components of a stopover site’s suitability, but we know relatively little about how changes in food availability affect the stopover ecology of migrating landbirds. we examined fruit and arthropod availability in three habitats, studied foraging behavior and diet, and investigated use versus availability for passerines migrating through southweste...

A 20-year capture-recapture study of alpine grasshoppers spanned three distinct sequences of abundance, featuring in turn dis-equilibrium, equilibrium and secondary cyclic equilibrium. This succession of population patterns in the most abundant species, Paprides nitidus, retained high stability between generations. It arose via superimposed life-cycle pathways and adaptive responses between gra...

Animal structures occasionally attain extreme proportions, eclipsing in size the surrounding body parts. We review insect examples of exaggerated traits, such as the mandibles of stag beetles (Lucanidae), the claspers of praying mantids (Mantidae), the elongated hindlimbs of grasshoppers (Orthoptera: Caelifera), and the giant heads of soldier ants (Formicidae) and termites (Isoptera). Developme...

Adopting the critical discourse analysis framework, in general, andFairclough’s (1989) critical text analysis, in particular, the current study aims atexamining 3 aspects of meaning, namely social relations, subject positions, andcontents in the conversation as well as vocabulary and grammar parts of Passages 1(an American textbook) and First Certificate (a British textbook) to find out whether...

Recent studies from East Asia and Canadian National Collection of Insects have established the utility of DNA barcoding technique in identification of true bugs. The present study is an expansion of the database by adding mitochondrial cytochrome c oxidase I (mtCOI) sequences from forty three species of indigenous true bugs of India. mtCOI gene analysis of infraorder Pentatomomorpha covering a ...
