Methane production in terrestrial arthropods.
We have screened more than 110 representatives of the different taxa of terrestrial arthropods for methane production in order to obtain additional information about the origins of biogenic methane. Methanogenic bacteria occur in the hindguts of nearly all tropical representatives of millipedes (Diplopoda), cockroaches (Blattaria), termites (Isoptera), and scarab beetles (Scarabaeidae), while s...
متن کاملSpeciation and phylogeography of Hawaiian terrestrial arthropods.
The Hawaiian archipelago is arguably the world's finest natural laboratory for the study of evolution and patterns of speciation. Arthropods comprise over 75% of the endemic biota of the Hawaiian Islands and a large proportion belongs to species radiations. We classify patterns of speciation within Hawaiian arthropod lineages into three categories: (i) single representatives of a lineage throug...
متن کاملImpact of Pollution on Terrestrial Arthropods
Pollution, the unwanted and undesirable presence of a chemical or compound, is unfortunately common. The problem is global, affecting all continents and nations, and frequently crossing natural and political boundaries. Specific occurrences may be quite localized (such as waste-water runoff from mining operations) or cover exceptionally broad geographic areas (like acidic precipitation in North...
متن کاملCarbon-dioxide sensing structures in terrestrial arthropods.
Sensory structures that detect atmospheric carbon dioxide have been identified and described to the subcellular level in adults of Lepidoptera, Diptera, Hymenoptera, Isoptera, Chilopoda, and Ixodidae, as well as in lepidopteran larvae. The structures are usually composed of clusters of wall-pore type sensilla that may form distinct sensory organs, often recessed in pits or capsules. In insects,...
متن کاملFactors Determining the Temperature of Terrestrial Arthropods in Sunlight
It has long been realized that the so-called cold-blooded animals are not always cold: in the sun their temperature may rise considerably above that of the surrounding air and even surpass that to which the homoiothenns are regulated. Some measurements have been made of such temperatures (Gunn, 1942), but the experimental difficulties are considerable and can hardly be faced with anything under...
