An annotated checklist of Wisconsin Scarabaeoidea (Coleoptera)

A survey of Wisconsin Scarabaeoidea (Coleoptera) conducted from literature searches, collection inventories, and three years offield work (1997-1999), yielded 177 species representing nine families, two of which, Ochodaeidae and Ceratocanthidae, represent new state family records. Fifty-six species (32% of the Wisconsin fauna) represent new state species records, having not previously been recorded from the state. Literature and collection distributional records suggest the potential for at least 33 additional species to occur in Wisconsin

New Species Records for Wisconsin False Click Beetles (Coleoptera: Eucnemidae),

In Wisconsin, Microrhagus opacus, Euryptychus ulkei and Fornax bicolor are recorded for the first time. Records for these three species are based on nine specimens, most of which were taken since 2008. Two specimens of M. opacus taken from a Grant County Malaise trap in the late 1970’s as part of a statewide gypsy moth parasitoid recovery project, were previously identified as Microrhagus audax. Most of the specimens reported herein were taken late in the collecting season, primarily during August. A checklist of the 20 genera and 41 species of Wisconsin Eucnemidae is also included

THE INFLUENCE OF TECHNOLOGICAL PROGRESS ON THE LONG RUN FARM LEVEL ECONOMICS OF SOIL CONSERVATION

The complementary interaction between topsoil depth and technical progress for winter wheat in the Palouse region was found to strengthen the long run payoff to conservation tillage. Nonetheless, conservation tillage was found to be competitive with conventional tillage only if its current yield disadvantages were eliminated. Conservation tillage was relatively more competitive on shallower topsoils and for longer planning horizons. Short-term subsidies coupled with research directed towards reducing the cost and yield disadvantages of conservation tillage in the Palouse were advocated to maintain long-term soil productivity.Land Economics/Use, Research and Development/Tech Change/Emerging Technologies,

Comments on a Major Range Extension of the Little-Known Acrocera bakeri (Diptera: Acroceridae)

The spider fly Acrocera bakeri Coquillett, 1904 (Diptera: Acroceridae) is reported as a new state record for Wisconsin. This is a major range extension, because this rarely-encountered species was previously known only from the western U.S., specifically Arizona, California, and Nevada. The taxonomic history of the species is briefly discussed and hypotheses are offered for its unexpected presence in Wisconsin

Carrion Beetles (Coleoptera: Silphidae) of Wisconsin

The first comprehensive faunal survey of the carrion beetles (Coleoptera: Silphidae) of Wisconsin is presented. Six genera and 14 species are recorded from the state, including a new state record, Heterosilpha ramosa (Say). Nicrophorus americanus Olivier was not recovered during this study. An annotated checklist includes species-specific geographical and temporal distributions, remarks on foods and habitat, and counties of specimen collections for each species

Nonassociative learning as gated neural integrator and differentiator in stimulus-response pathways

Nonassociative learning is a basic neuroadaptive behavior exhibited across animal phyla and sensory modalities but its role in brain intelligence is unclear. Current literature on habituation and sensitization, the classic "dual process" of nonassociative learning, gives highly incongruous accounts between varying experimental paradigms. Here we propose a general theory of nonassociative learning featuring four base modes: habituation/primary sensitization in primary stimulus-response pathways, and desensitization/secondary sensitization in secondary stimulus-response pathways. Primary and secondary modes of nonassociative learning are distinguished by corresponding activity-dependent recall, or nonassociative gating, of neurotransmission memory. From the perspective of brain computation, nonassociative learning is a form of integral-differential calculus whereas nonassociative gating is a form of Boolean logic operator – both dynamically transforming the stimulus-response relationship. From the perspective of sensory integration, nonassociative gating provides temporal filtering whereas nonassociative learning affords low-pass, high-pass or band-pass/band-stop frequency filtering – effectively creating an intelligent sensory firewall that screens all stimuli for attention and resultant internal model adaptation and reaction. This unified framework ties together many salient characteristics of nonassociative learning and nonassociative gating and suggests a common kernel that correlates with a wide variety of sensorimotor integration behaviors such as central resetting and self-organization of sensory inputs, fail-safe sensorimotor compensation, integral-differential and gated modulation of sensorimotor feedbacks, alarm reaction, novelty detection and selective attention, as well as a variety of mental and neurological disorders such as sensorimotor instability, attention deficit hyperactivity, sensory defensiveness, autism, nonassociative fear and anxiety, schizophrenia, addiction and craving, pain sensitization and phantom sensations, etc

Effects of Parkinson’s disease on optic flow perception for heading direction during navigation

Visuoperceptual disorders have been identified in individuals with Parkinson’s disease (PD) and may affect the perception of optic flow for heading direction during navigation. Studies in healthy subjects have confirmed that heading direction can be determined by equalizing the optic flow speed (OS) between visual fields. The present study investigated the effects of PD on the use of optic flow for heading direction, walking parameters, and interlimb coordination during navigation, examining the contributions of OS and spatial frequency (dot density). Twelve individuals with PD without dementia, 18 age-matched normal control adults (NC), and 23 young control adults (YC) walked through a virtual hallway at about 0.8 m/s. The hallway was created by random dots on side walls. Three levels of OS (0.8, 1.2, and 1.8 m/s) and dot density (1, 2, and 3 dots/m2) were presented on one wall while on the other wall, OS and dot density were fixed at 0.8 m/s and 3 dots/m2, respectively. Three-dimensional kinematic data were collected, and lateral drift, walking speed, stride frequency and length, and frequency, and phase relations between arms and legs were calculated. A significant linear effect was observed on lateral drift to the wall with lower OS for YC and NC, but not for PD. Compared to YC and NC, PD veered more to the left under OS and dot density conditions. The results suggest that healthy adults perceive optic flow for heading direction. Heading direction in PD may be more affected by the asymmetry of dopamine levels between the hemispheres and by motor lateralization as indexed by handedness.Published versio

We Didn’t Fear the Reader: Embracing New Service Models With Staff and Patron Input

The book Transforming Acquisitions and Collection Services: Perspectives on Collaboration Within and Across Libraries explores new ways libraries can reach new standards in service, quality, and efficiency through cross-functional collaboration in acquisitions. Within libraries, the library acquisitions function can be combined with other units through close working relationships to support each group\u27s work. This chapter, titled We Didn\u27t Fear the Reader: Embracing New Service Models with Staff and Patron Input, details the organizational change and shifts in collection development philosophy at the Lehigh Libraries that led to more patron-centered policies and programs
