Experimental hybridisation between X0 and XY chromosome races in the grasshopper Podisma sapporensis Shir. (Orthoptera, Acrididae). I. Cytological analysis of embryos and F1 hybrids.

Market basket analysis of grasshopper (Orthoptera: Acrididae) assemblages in eastern Wyoming: A 17 year case study using associative analysis for ecological insights of grasshopper outbreaks: Market Basket Analysis (MBA) and Community Ecology

1. This study utilised an associative analysis (AA) technique named market basket analysis (MBA) to investigate whether particular grasshopper (Orthoptera: Acrididae) species associations are common during outbreaks (>9.6 grasshoppersm−2) that last >3 years. This study is the first of its kind to use MBA on animal communities. 2. A subset of the 17 years of grasshopper density data from theWyom...

Susceptibility to Disease Across Developmental Stages: Examining the Effects of an Entomopathogen on a Grasshopper (Orthoptera: Acrididae) Pest

Organization of some repetitive DNAs and B chromosomes in the grasshopper Eumastusia koebelei koebelei (Rehn, 1909) (Orthoptera, Acrididae, Leptysminae)

B chromosomes occur in approximately 15% of eukaryotes and are usually heterochromatic and rich in repetitive DNAs. Here we describe characteristics of a B chromosome in the grasshopper Eumastusia koebelei koebelei (Rehn, 1909) through classical cytogenetic methods and mapping of some repetitive DNAs, including multigene families, telomeric repeats and a DNA fraction enriched with repetitive DN...

Determination by GISH and FISH of hybrid status in Lilium.

In the genus Lilium, plants obtained from crosses, especially between distant relatives, are not always hybrids because embryos can develop as a result of apomixis. These plants constitute genetic material of the maternal parent only. In this study, verification of hybrid status of plants which have been obtained from the crosses 'Marco Polo'xLilium henryi and 'Expression'xL. henryi was perform...

Frequent assimilation of mitochondrial DNA by grasshopper nuclear genomes.

Multiple copies of mitochondrial-like DNA were found in the brown mountain grasshopper, Podisma pedestris (Orthoptera: Acrididae), paralogous to COI and ND5 regions. The same was discovered using the ND5 regions of nine other grasshopper species from four separate subfamilies (Podisminae, Calliptaminae, Cyrtacanthacridinae, and Gomphocerinae). The extra ND5-like sequences were shown to be nucle...
