Dytiscidae and Noteridae of Wisconsin (Coleoptera). I. Introduction, Key to Genera of Adults, and Distribution, Habitat, Life Cycle, and Identification of Species of Agabetinae, Laccophilinae and Noteridae
Collected from Wisconsin were 83,710 adult and 5,600 larval Dytiscidae representing 148 species, and 95 adult Noteridae representing two species. A key to genera is presented, which includes names of species in genera that are monotypic in WIsconsin. Information on distribution and abundance in Wisconsin, range, habitat, life cycles, and identification are included for species in the dytiscid subfamilies Agabetinae and Laccophilinae, and the family Noteridae. Also included are keys to species of adult and larval Laccophilus found in Wisconsin
Seasonal Correction Factors for the Biotic Index
For evaluation of streams with the biotic index (BI), samples of arthropods should be collected in the spring before degree day accumulations of mean air temperatures above 4.5°C reach 440° in warm-water streams, and before they reach 1050° in cold-water streams that remain below 20°e. Sampling in the fall may be resumed 60 days after the 440 degree day accumulation in warm-water streams and 45 days after the 1050 degree day accumulation in cold-water streams. Stream temperature had no effect on the BI, except as it affected seasonal differences. Current had less effect on the BI than anticipated, but currents below 0.3 m/sec should be avoided
Of Miracles and Evidential Probability: Hume’s “Abject Failure” Vindicated
This paper defends David Hume's "Of Miracles" from John Earman's (2000) Bayesian attack by showing that Earman misrepresents Hume's argument against believing in miracles and misunderstands Hume's epistemology of probable belief. It argues, moreover, that Hume's account of evidence is fundamentally non-mathematical and thus cannot be properly represented in a Bayesian framework. Hume's account of probability is show to be consistent with a long and laudable tradition of evidential reasoning going back to ancient Roman law
Semiaquatic Hemiptera of Wisconsin
Twenty-six species in five families of semi aquatic Hemiptera were collected in Wisconsin and as many as four more may occur. Keys to all of these species are provided along with notes on their distribution, abundance, and identification. Most species were distributed statewide, except that Gerris insperatus and Rhagovelia obesa were most common in the north, and Garris marginatus, Rhagovelia oriander, and Neogerris, Pheumatobates, hestone, were most common in the south. Metrobates, Neogerris, Rheumatobates, Trepebates, Mesovelia, and Rhagovelia apparently overwintered as eggs since adults were absent in the spring. Adults of other genera were collected from early spring to autumn
Gyrinidae of Wisconsin, With a Key to Adults of Both Sexes and Notes on Distribution and Habitat
More than 25,000 adult gyrinids that include 24 species were studied from all areas of Wisconsin. Dineutus discolor, Gyrinus aeneolus, G. analis, G. bifarius, and G. marginellus are lotic; D. assimilis, G. aquiris, G. confinis, and G. dichrous apparently breed in both lotie and lentic habitats; and the remaining species probably breed primarily in deep ponds or littoral areas of lakes and impoundments. Most collections were from streams in late summer and autumn because adults of almost all lentic species fly to streams to overwinter and these overwintering aggregations were easily collected. A key to adults of Wisconsin species was developed, and by using the gonocoxae and secondary sexual characters, females can be identified as accurately as males
Dytiscidae and Noteridae of Wisconsin (Coleoptera). V. Distribution, Habitat, Life Cycle, and Identification of Species of Hydroporinae, Except \u3ci\u3eHydroporus\u3c/i\u3e Clairville Sensu Lato
Thirty species in 11 genera of Hydroporinae were collected in Wisconsin over the past 32 years, excluding those in Hydorporus s.l. Fourteen species of Hygrotus were found; other genera were represented by one to four species. Species keys and notes on identification are provided for adults of all species that occur or may occur in Wisconsin. Information on distribution and abundance in Wisconsin, habitat, and life cycle is provided for each species based on a study of 34,628 adults. Life cycles were predominantly univoltine, with adults overwintering and larvae completing development from late spring to late summer, depending on the species. Most adults apparently overwinter in aquatic habitats, except those of Laccornis and Hygrotus compar, which probably overwinter in terrestrial habitats
[Review of] David Mason, ed. Explaining Ethnic Differences: Changing Patterns of Disadvantage in Britain
A series of communal disturbances took place in several north of England towns during the spring and summer of 2001. They were notable for the participation of young, male Asians, a significant proportion of them Muslims...as against African-Caribbeans (21)
