<em>Abstract</em>.—In-season homing of Pacific lampreys <em>Lampetra tridentata </em>was investigated using radiotelemetry in the lower Columbia River from 1998 through 1999. A total of 50 Pacific lampreys were captured: 25 at Willamette Falls (river kilometer [rkm] 45 on the Willamette River, a tributary to the Columbia River, with its confluence at rkm 163) and 25 at Bonneville Dam (rkm 238 on the Columbia River). Each fish was fitted with a radio transmitter, transported, and released in the Columbia River approximately 26 km downstream from the confluence of the Willamette River. Movement of the radio-tagged Pacific lampreys was monitored for several months using mobile and fixed receiver stations to observe rates of homing towards the site of original capture. Results indicated that the lampreys exhibited nonsignificant in-season homing fidelity (<em>p</em> = 0.622) based on the null expectation that one-half of the total recoveries would home and the other half would stray. Final location classifications were 17 homed, 20 strayed, and 13 undetermined. The undetermined classification included individuals that were not detected upstream of the confluence of the Willamette River or in other Columbia River tributaries. Final location classifications were not influenced by fish length (<em>p</em> = 0.594). Although considered weak swimmers, Pacific lampreys were capable of traveling at velocities near 2.5 km/h and sustaining that activity for at least 24 h.

AbstractOzognathus cornutus (LeConte, 1859) (Coleoptera: Ptinidae: Ernobiinae), species native to North America, is a saproxylophagous species and is known to feed on decaying tissues within conspicuous galls and on vegetal decaying organic material such as dried fruits or small wood shavings and insect excrements in galleries made by other woodboring species. A few years after the first record in 2011, its naturalization in Italy is here reported. The insect was found as successor in galls of Psectrosema tamaricis (Diptera Cecidomyiidae), Plagiotrochus gallaeramulorum, Andricus multiplicatus and Synophrus politus (Hymenoptera Cynipidae). The galls seem to have played an important ecological role in speeding up the naturalization process. The lowest proportion of galls used by O. cornutus was recorded for P. tamaricis (23%), the only host belonging to Cecidomyiidae, while the percentages recorded for the other host species, all Cynipidae forming galls on oaks, were higher: 43.6%, 61.1% and 76.9% in A multiplicatus, S. politus and P. gallaeramulorum, respectively. Although O. cornutus is able to exploit other substrates like dried fruits and vegetables, for which it could represent a potential pest, it prefers to live as a successor in woody and conspicuous galls, which thus can represent a sort of natural barrier limiting the possible damages to other substrates.

The late Miocene Chinese hipparions are morphologically diversified showing similarity to both western Old World's and North American forms. Two Chinese taxa that are phylogenetically related to western Old World's forms are Hipparion fossatum (= H. forstende) from Baode (Shanxi) and H. hippidiodus from Qingyang (Gansu) and Baode. The former is related to H. mediterraneum and the latter to H. urmiense - platygenys from the Turolian localities in the western Old World. H. fossatum and H. hippidiodus are associated with the “dorcadoides” (open-land) and “mixed” faunas in northern China. Hipparion fossatum that is characterized by POF located close to the orbit co-occurs with large and morphologically specialized form, H. dermatorhinum in Baode (Loc.30). H. hippidiodus with reduced POF is discovered with smaller H. coelophyes in Loc. 43, 44 (Baode) and Loc. 115 (Gansu).The hipparions associated with the “gaudryi” (forest) fauna are characterized by well defined and small POF located far from the orbit. Those forms are: H. platyodus from Loc. 70; H. ptychodus from Loc. 73; H. tylodus from Hsi-Liang in Yushe - Wuxiang basins; and H. sefvei from Loc. 12 at Xin-an in Henan province. H. coelophyes from Baode (Loc.43 & 44) and Qingyang (Loc. 115) also show similar facial morphology to the these forms, although it has small size and shallow POF. Those forms are similar in facial and dental morphology to Hipparion sensu stricto and some species of Cormohipparion in North America.The assemblages of Chinese hipparions are composed of two groups whose members are phylogenetically similar to the forms from both western part of Eurasia and North America. The “gaudryi” fauna is considered younger than the other two on the basis of faunal analyses. The similarity in hipparionine taxonomy between northern China and North America in the latest Miocene is an evidences for possible faunal interchange(s) occurred during that period, as suggested by taxonomic analyses on carnivores and proboscideans in eastern half of Eurasia and North America.

Abstract A stochastic model of ground motion has been used as a basis for comparison of data and theoretically-predicted relations between mN (commonly denoted by mbLg) and moment magnitude for eastern North America (ENA) earthquakes. mN magnitudes are recomputed for several historical ENA earthquakes, to ensure consistency of definition and provide a meaningful data set. We show that by itself the magnitude relation cannot be used as a discriminant between two specific spectral scaling relations, one with constant stress and the other with stress increasing with seismic moment, that have been proposed for ENA earthquakes.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.

Holarctic Species

Anoplius tenuicornis (Tournier) is a holarctic species with a broad distribution both in Europe (Wolf 1967) and North America (Wasbauer and Kimsey 1985). Despite the widespread occurrence of the species, individuals are not frequently encountered, so it is not surprising that biological information on it has not been available for North America and very little for Europe. Richards and Hamm (1939) gave two fragmentary reports of some significance on A. tenuicornis in England, reported as A. piliventris (Morawitz). In one case, cocoons of the wasp were found in dead thistle stems. In the other, an old burrow of Ectemnius continuus (Fabricius) (Sphecidae) (reported as Solenius) in rotten wood contained a series of wasp cocoons and fragments of clubionid spiders, the presumed prey.

The Difference

Abstract Indigenous cultures of North America confronted a problem of knowledge different from that of canonical European philosophy. The European problem is to identify and overcome obstacles to the perfection of knowledge as science, while the Indigenous problem is to conserve a legacy of practice fused with a territory. Complicating the difference is that one of these traditions violently colonized the other, and with colonization the Indigenous problem changes. The old problem of inter-generational stability cannot be separated from the post-colonial problem of sovereignty in the land where the knowledge makes sense. I differentiate the question of the value of knowledge (Part 1), and its content (Part 2). The qualities these epistemologies favor define what I call ceremonial knowledge, that is, knowledge that sustains a ceremonial community. The question of content considers the interdisciplinary research of Indigenous and Traditional Ecological Knowledge, as well as the issue of epistemic decolonization.

Feminist Theories

This major research paper relates my experiences as a Chinese woman to those of other East Asian women while exploring why East Asian women continue to be sexualized and ethnicized. My paper is based on the feminist standpoint and anti-racist feminist theories, and feminist and post-modern methodologies. The focus is on the Chinese immigration experience to North America, and on Chinese women's lives, with some consideration of Korean and Japanese women because the latter two share similarities in experiences of homogenization of East Asian women. I argue that the experiences of every woman are unique because of their race, migration and settlement experiences. I borrow Ang's (2001) term "togetherness in differences" to describe our experiences. The stereotypes of East Asians and East Asian women are not created in a vacuum; rather they are the direct result of the dominant culture oppressing the "other" in the effort to subordinate them.
