Fennica 23: 127—139. Morphology and acoustic signals of four species of the subfamily Gompho- cerinae (Orthoptera: Acrididae) from Turkey are studied.

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.

Page 1/21 Abstract The red imported re ant (RIFA), Solenopsis invicta Buren is native to South America and is known as a global problematic invasive species. This study focused on the molecular response of RIFA by comparing gene expression proles after exposing ants to low (10℃) and high (40℃) temperature stress and comparing to untreated controls (30℃). A total of 99,085 unigenes were obtained, of which 19,154 were annotated with gene descriptions, gene ontology terms, and metabolic pathways. 86 gene ontology (GO) functional sub-groups and 23 EggNOG terms resulted. Differentially expressed genes (DEGs) with log2FC ≥ 10 were screened and were compared at different temperatures. We found 203, 48, and 66 specic DEGs co-regulated at 10, 20, and 40℃. Comparing transcriptome proles for differential gene expression resulted in various DE proteins and genes, including cytochrome P450, NADH dehydrogenase subunit 1, cuticle protein and heat shock protein (HSP) which have previously been reported to be involved in cold and high temperature resistance.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1).

  • Field Guide to Some of the Common Grasshoppers of the Front Range of Colorado
    Field guide to some of the common grasshoppers of the Front Range of Colorado Instructions: The following guide presents the grasshopper species most commonly found along an elevational gradient from the plains of Boulder, Colorado, to the subalpine that lies to the west. Use this guide to identify the species that are found during each weekly sample at your designated site. This will help you determine whether climate change is impacting the timing to adulthood of each community. Grasshoppers of the Front Range There are 548 species of North American grasshoppers and 133 of these occur in Colorado. Only about a dozen of these species are considered important pests on rangelands, with five of these causing most problems on crops. Within the Front Range of Colorado, 72 species can be found, although most are relatively uncommon. The most commonly encountered species along our lower foothills (1752m) to subalpine (3000 m) transect can be placed into 3 groups (subfamilies); Gomphocerinae, Melanoplinae and Oedipodinae. The Gomphocerinae (slant-faced grasshoppers) are grass specialists that tend to be small and are the grasshoppers commonly heard in meadows chorusing during the day. The Melanoplinae (spur-throated grasshoppers) are the most commonly encountered grasshoppers and are primarily forb feeders. Melanoplinae are small (but some can be large) and several of these species tend to be short winged and cannot actively fly, They do not chorus. Most of the Oedipodinae (banded-winged grasshoppers) tend to be grass feeders or herbivorous (both grass and forb feeding) and are rarely solely forb feeders. These grasshoppers are commonly found in open areas where they bask and display, they vary considerably in size, and are all active fliers that often use their wings to make loud clicking sounds.

In some grasshopper species, their evolution has led to many B chromosome morphotypes. We studied the Bs in nine species (Nocaracris tardus, Nocaracris cyanipes, Aeropus sibiricus, Chorthippus jacobsoni, Chorthippus apricarius, Bryodema gebleri, Asiotmethis heptapotamicus songoricus, Podisma sapporensis, and Eyprepocnemis plorans), analyzing their possible origin and further development. The studied Bs consisted of C-positive or C-positive and C-negative regions. Analyzing new data and considering current hypotheses, we suggest that Bs in grasshoppers could arise through different mechanisms and from different chromosomes of the main set. We gave our special attention to the Bs with C-negative regions and suggest a new hypothesis of B chromosome formation from large or medium autosomes.
