Invertebrate Abundances And Diversity Of A Six Year Old Organic Apple Orchard In Northwest Arkansas, Cory Johnson, Brina Smith, Mary C. Savin
Invertebrate Abundances And Diversity Of A Six Year Old Organic Apple Orchard In Northwest Arkansas, Cory Johnson, Brina Smith, Mary C. Savin
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Ground cover mulch applications in perennial systems can have multiple benefits, one of which may be to enhance the size and diversity of the ground surface faunal community. To determine if ground cover and organic fertilizer applications altered invertebrate communities, litters in an experimental 0.4-ha organic apple orchard in Fayetteville, Ark. were sampled during a four week period beginning in February 2012. The orchard was planted in 2006 in a replicated 4 × 3 factorial design with organic ground cover and fertilizer treatments applied annually each April. Invertebrates were extracted using Berlese funnels and hand sorting techniques. Ground covers (wood …

Management In A Neotropical Show Cave: Planning For Invertebrates Conservation, Thais Giovannini Pellegrini, Rodrigo Lopes Ferreira
Management In A Neotropical Show Cave: Planning For Invertebrates Conservation, Thais Giovannini Pellegrini, Rodrigo Lopes Ferreira
International Journal of Speleology
Lapa Nova is a dolomitic cave about 4.5 km long located in northwestern Minas Gerais state, Brazil. The cave experiences intense tourism, concentrated over a single period of the year, during the Feast of Our Lady of Lapa. In order to evaluate the impacts felt by the invertebrate community from this tourism, a new methodology was proposed. Four types of areas (intense visitation area, outlying visitation areas, moderate visitation areas and no-visitation areas) were sampled for invertebrates. There was one sampling prior and another on the last day of the 128th feast, to evaluate the effects of visitation on …

The World’S Deepest Subterranean Community - Krubera-Voronja Cave (Western Caucasus), Alberto Sendra, Ana Sofia P.S. Reboleira
International Journal of Speleology
Subsurface biota extends over a wide variety of habitats that can be spatially interconnected. The largest communities of this subsurface biota inhabit cavities and are well known mainly in caves where biologists are able to have access. Data about deep subterranean communities and arthropods living under one thousand meters was unknown.
An expedition to world’s deepest cave, Krubera-Voronja in Western Caucasus, revealed an interesting subterranean community, living below 2000 meters and represented by more than 12 species of arthropods, including several new species for science. This deep cave biota is composed of troglobionts and also epigean species, that can penetrate …
Diversity And Community Assembly Patterns Of Epigean Vs. Troglobiont Spiders In The Iberian Peninsula, Pedro Cardoso
Diversity And Community Assembly Patterns Of Epigean Vs. Troglobiont Spiders In The Iberian Peninsula, Pedro Cardoso
International Journal of Speleology
Cave-obligate organisms usually have smaller ranges and their assemblages have higher beta diversity than their epigean counterparts. Phylogenetic and functional diversity is usually low in cave communities, leading to taxonomic and functional disharmony, with entire groups missing from the subterranean realm. The objective of this work is to compare range, beta diversity, phylogenetic and functional diversity, taxonomic and functional disharmony of epigean versus troglobiont spiders in the Iberian Peninsula.
The median extent of occurrence was found to be 33 times higher for epigean than for cave species. Beta diversity was significantly higher for troglobiont assemblages. Cave assemblages present lower phylogenetic …

Maine Policy Review
The authors describe two invasive insect forest pests; the hemlock wooly adelgid (HWA) has already arrived in Maine, and the emerald ash borer (EAB) has not yet reached Maine, but will have a devastating effect on the state’s Indian basketmakers when it does arrive. With funding through Maine’s Sustainability Solutions Initiative, teams based at the University of Maine and Unity College are bringing together faculty, students, and stakeholders to better understand the threats that infestations pose to the ecology and economy of the Maine’s forests and to longstanding cultural practices.

Population Structuring And Transmission Dynamics Of A Laboratory Colony Of Gromphadorholaelaps Schaeferi: A Symbiotic Mite Of The Madagascar Hissing Cockroach Gromphadorhina Portentosa, D. J. Richardson
Journal of the Arkansas Academy of Science
Gromphadorholaelaps schaeferi is a symbiotic mite associated with the Madagascar hissing cockroach Gromphdorhina portentosa. The population structuring of G. schaeferi is described based on examination of 19,421 mites collected from 1,915 individuals of G. portentosa taken from a large laboratory colony. The mites exhibited an overall prevalence of 50.7% and mean intensity (+SE) of 20.0 (+0.6) with an infestation intensity range of 1-116, and relative abundance (+SE) of 10.1 (+0.4). Both prevalence and mean intensity of infestation exhibited a dramatic increase with increasing cockroach size/age. By the time cockroaches reach 40 mm the prevalence is nearly 100%. Mean intensity increases …
