Patterns of arthropod distribution and determinants of arthropod assemblage composition in a natural West African savannah
This study investigated patterns of arthropod community organisation and the processes structuring these communities on a range of different tree species in a natural West African savannah (Comoé National Park, Côte d'Ivoire). It described and analysed patterns of arthropod distribution on the …

Modeling Arthropod Traits in a Bayesian Framework
As ectothermic organisms cannot fully regulate their own body temperature, they are dependent on external sources of heat. Because of this, temperature has a large influence on many of their physiological traits that affect fitness, such as development time or lifespan, which in turn, alters their …

Zika Modulates Arthropod Histone Methylation in Mosquito Cells
… is known whether ZIKV exerts methylation in arthropod vectors. In this study, I show that ZIKV modulates S-adenosyl methionine (SAMe) synthase, an enzyme involved in the production of SAMe, and histone methylation for its survival in <em>Aedes albopictus</em> derived C6/36 cell line. …

Bioinformatics and Next Generation Sequencing: Applications of Arthropod Genomes
… annotation, and comparative genomics, using arthropods as case studies: (1) by sequencing and analyzing the genomes of three Tetranychus spider mites with three completely different feeding behaviors, we uncovered genomic signature variations and indicative of pest adaptations; (2) we …

Arthropod-borne infections in the United Kingdom and Saudi Arabia
Arthropod vectors can transmit different diseases that are both a significant and widespread cause of mortality and morbidity in both human and wildlife species. However, further studies are required to identify the role of wildlife species as reservoir hosts for such infections. In some countries, …

Arthropod and vertebrate determinants for horizontal transmission of Rickettsia felis
… States, R. felis has been detected in numerous arthropod species in 28 countries around the world. Additionally, as the etiologic agent of flea-borne rickettsiosis, R. felis can cause disease in humans, with patients presenting with clinical symptoms typical of rickettsial diseases including: …

Alternative Splicing Expands Spatiotemporal Expression Complexity of Arthropod N -Cadherin
… we use in silico approaches to show that the arthropod N-Cadherin gene has maintained exactly the same genomic organization, a common promoter and three sets of mutually exclusive alternatively-spliced exons (MEs), for over 400 million years. Furthermore, in vivo studies demonstrated that …

Effects of postharvest oils on arthropod pests of citrus / by Peter Taverner
This study investigates the effects of a number of petroleum and vegetable oils against citrus pests.

Protozoan, helminth and arthropod parasites of the gray squirrel in southwestern Virginia
… examined for helminths and 106 for ectoparasitlc arthropods. The incidence of coccidiosis was 91% in which five species were described and identified with the genus, Eimerla. The sporozoan, Hepatozoon griseiscuri Clark. 1958, occurred In the blood as evidenced by a 58% incidence in stained blood …

PLANT AND ARTHROPOD COMMUNITIES OF ALPINE ICE-RELATED LANDFORMS: ECOLOGICAL AND BIOGEOGRAPHIC IMPORTANCE
… (Valle et al. 2022a-b) describe plants and arthropod communities of threatened glacial sites (Peirabroc, Clapier and Calderone glaciers) in peripheral mountain chains (Maritime Alps and Apennines, Italy, respectively). In these studies also important environmental parameters (e.g. debris …

Arthropod Predation in Brassica Agroecosystems: Effects of Latitude, Community Composition, and Diet Breadth
Arthropod predators provide crucial pest management services by consuming herbivore prey in agroecosystems. Yet, variation in arthropod predation strength among cropping systems and regions can prevent farmers from taking advantage of this alternative pest management strategy. This research …

Ground-Dwelling Arthropod Community Structure of Saskatchewan's Agroecosystems and Seeded Grasslands
Ground-dwelling arthropods hold a critical role in maintaining the health and function of agroecosystems in the Canadian prairie landscape. However, the distribution of many groups is often limited to non-crop habitats, such as roadside ditches or distantly spaced grassland refuges. The high …

Drivers of plant and arthropod diversity and community structure in a grassland ecosystem
… spatial scales in governing plant diversity and arthropod community structure. Plant diversity is generally hypothesized to be limited by local competition/productivity ("niche limitation hypothesis", "NLH"), and/or by regional species pools/dispersal ("species pool hypothesis", "SPH"); however, …

Impact of mustards (Brassicaceae) grown as cover crops on non-target arthropod communities
… varieties grown as cover crops on non-target arthropod communities and diversity were investigated in 2008. The abundance of carabid beetles, collembolans, and mites were monitored before, during, and after the seeding, growth, and incorporation of two mustard varieties (‘Tilney’ and ‘Florida …
