Review Of Evolution And Cognition, Edited By Cecilia Heyes And Ludwig Huber., Alan Kamil
Review Of Evolution And Cognition, Edited By Cecilia Heyes And Ludwig Huber., Alan Kamil
Papers in Behavior in Biological Sciences
Heyes and Huber have edited a volume that surveys much of the current research into cognition in animals, reflecting the strengths and weaknesses of this field. The book is divided into five sections. In the first part, titled “Orientations,” four authors lay out their basic general views of the field. The first two chapters in this section are by the editors. First, Heyes makes the case for an approach to evolutionary psychology that she labels “in the round,” an approach that would encompass studies of human and nonhuman animals alike and include a broad range of contemporary evolutionary approaches. This …
Managing Minnesota's Recovered Wolves, L. David Mech
Managing Minnesota's Recovered Wolves, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The Minnesota wolf (Canis lupus) population was estimated by the Minnesota Department of Natural Resources at 2,450 during winter 1997-1998 and had increased at an average annual rate of 4.5°% since winter 1988-1989. The population may be removed from the federal endangered species list by 2002, and management would then return to the state. A federal recovery team recommended a population goal of 1,250-1,400 wolves for Minnesota, with none in the agricultural region. A plan approved by the Minnesota legislature, however, continues the protection of wolves, except for pet and livestock depredation control, for at least 5 years …

New Host And Geographic Records For Two Protostrongylids In Dall's Sheep, Susan J. Kutz, A. M. Veitch, Eric P. Hoberg, B. T. Elkin, Emily J. Jenkins, L. Polley
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Biodiversity survey and inventory have resulted in new information on the distribution of Protostrongylidae in Dall’s sheep (Ovis dalli dalli) from the Northwest Territories (Northwest Territories, Canada) and from Alaska (Alaska, USA). In 1998, Parelaphostrongylus odocoilei adults were found for the first time in the skeletal muscles of Dall’s sheep in the Mackenzie Mountains (Northwest Territories). Adult P. odocoilei were associated with petechial and ecchymotic hemorrhages and localized myositis; eggs and larvae in the lungs were associated with diffuse granulomatous pneumonia. Experimental infections of the slugs Deroceras laeve and Deroceras reticulatum with dorsal-spined first-stage larvae assumed to be …
Records For The Utilization Of Prunus As A Larval Foodplant By 71 Species Of Lepidoptera In Northeast California, Laurence L. Crabtree, Ron Leuschner
Records For The Utilization Of Prunus As A Larval Foodplant By 71 Species Of Lepidoptera In Northeast California, Laurence L. Crabtree, Ron Leuschner
The Taxonomic Report of the International Lepidoptera Survey
Twenty-six sites in five northeastern California counties (Shasta, Modoc, Plumas, Lassen, Tehama) were surveyed from 1991 to 1999 for the presence of lepidopteran larvae on naturally occurring shrubs of the genus Prunus. To date, a total of seventy-one species of Lepidoptera from seventeen families have been documented to utilize one or more of the area’s three Prunus species (P. emarginata, P. subcordata, and P. virginiana var. demissa).

Nine New Species Of Lacinipolia (Noctuidae) From Arizona, California And Vicinity, Charles L. Selman, Ron Leuschner
The Taxonomic Report of the International Lepidoptera Survey
This article formalizes the taxonomic conclusions of the senior author’s 1975 successful doctorate dissertation. The nine new species defined in that 1975 dissertation are here formally described in compliance with the rules of the International Code of Zoological Nomenclature (ICZN). The authors have essentially abstracted the original 447 page dissertation and designated types. The new Lacinipolia species are: delongi, aileenae, triplehorni, bucketti, baueri, sharonae, martini, fordi, and franclemonti. The purpose of this paper is simply to make these names available to the scientific community and professional researchers by making them ICZN-compliant.

The Biology, Life History, And Taxonomy Of Celastrina Neglectamajor (Lycaenidae: Polyommatinae)., Harry Pavulaan, David M. Wright
The Taxonomic Report of the International Lepidoptera Survey
The biology and life history of Celastrina neglectamajor is described. This lycaenid butterfly was first described from West Virginia, United States by 19th century lepidopterist, William H. Edwards, as a redescription of Lycaena pseudargiolus (Boisduval & Le Conte). Edwards provided evidence of its unique late spring flight, Appalachian affinity, and larval host Cimicifuga racemosa (Ranunculaceae). Edwards and subsequent authors, most notably Samuel Scudder of New England, treated it as an infrasubspecific form of the common eastern Celastrina ladon. In 1908 Tutt applied the form name neglectamajor, describing it from one of Edwards’ 1884 figures. For nearly a century, …

Electrophysiological Studies Of Olfaction In The Whip Spider Phrynus Parvulus (Arachnida, Amblypygi), Eileen Hebets, Reginald F. Chapman
Eileen Hebets Publications
The olfactory response of the whip spider Phrynus parvulus from Costa Rica was examined using a technique analogous to that used for insect electroantennograms on the tarsi of the antenniform legs which bear multiporous sensilla. Responses to 42 chemicals representing different chain lengths of alkanes, carboxylic acids, alcohols, aldehydes, and ketones, as well as some esters, monoterpenes, and phenolics were examined. Fifty-four percent of the chemicals tested elicited responses. Concentration–response curves were generated for guaiacol, hexanal, methyl salicylate, benzaldehyde, octanoic acid, and linalool. Guaiacol, benzaldehyde, and hexanol elicited the greatest responses and no differences were detected between the sexes. Compounds …

Description Of A New Subspecies Of Poanes Aaroni (Hesperioidae: Hesperiinae) From The West Central Gulf Coast Of The Southern United States, Ronald R. Gatrelle
The Taxonomic Report of the International Lepidoptera Survey
Poanes aaroni bordeloni is described from Jefferson County, Texas, United States. This taxon is part of a lepidopteran community endemic to the west central area of the United States Gulf Coast between Mobile Bay, Alabama and Galveston Bay, Texas. As such, bordeloni is defined taxonomically by its evolutionary development as much as by its facies. Bordeloni is the largest aaroni subspecies. Bordeloni males are marked much like those of P. a. howardi both dorsally and ventrally. Bordeloni females usually have the fulvous spotting on the dorsal forewings reduced as in P. a. minimus females while …

School of Natural Resources: Faculty Publications
Two new records of Tadarida brasiliensis mexicana are reported from Nebraska. The literature records of this taxon from the central United States are summarized. In this region of North America, these bats occupy a “natal range” where the species carries on regular reproductive activities and the populations are relatively stable, including California, Arizona, New Mexico, Texas, and Oklahoma. To the north of the natal range of T. b. mexicana is a “pioneering zone” where, under favorable conditions, the species is capable of reproducing and conducting its normal activities. The pioneering zone of the Mexican free-tailed bat includes Barber and Comanche …
Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman
Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman
School of Natural Resources: Faculty Publications
New distributional records are presented for 20 species of mammals in Nebraska. The majority of these records appear to represent changes in geographic distribution rather than just better sampling in poorly known areas. One group of mammals, including the opossum, northern myotis, evening bat, red bat, woodchuck, white-footed mouse, and gray fox, is expanding westward, probably in response to increasing woodlands along river systems. Another group, including the meadow vole, masked shrew, and least weasel, is expanding southward, possibly in response to new prey species and changing microclimates. The eastern woodrat appears to be expanding northward in eastern Nebraska. The …

A Phylogenetic Hypothesis For Species Of The Genus Taenia (Eucestoda: Taeniidae), Eric P. Hoberg, Arlene Jones, Robert L. Rausch, Keeseon S. Eom, Scott Lyell Gardner
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Cladistic analysis of a numerical data matrix describing 27 characters for species of Taenia resulted in four most parsimonious phylogenetic trees (174 steps; consistency index = 0.28; homoplasy index = 0.72; retention index = 0.48). Monophyly for Taenia is diagnosed by the metacestode that is either a cysticercus or a form derived from a bladder-like larva; no other unequivocal synapomorphies are evident. Tree structure provides no support for recognition of a diversity of tribes or genera within the Taeniinae: Fimbriotaeniini and Taeniini have no phylogenetic basis. Hydatigera, Fimbriotaenia, Fossor, Monordotaenia, Multiceps, Taeniarhynchus, Tetratirotaenia must …

Breeding Season Demography And Movements Of Eastern Towhees At The Savannah River Site, South Carolina, David G. Krementz, Larkin A. Powell
School of Natural Resources: Faculty Publications
The Eastern Towhee (Pipilo erythrophthalmus) has undergone population declines across much of its range, especially in New England. Despite being a widespread and, at one time, a common species, relatively little is known about its natural history, ecology, or demographics. We conducted baseline research on Eastern Towhees at the Savannah River Site, South Carolina, in 1995 and 1996 to estimate breeding season survival rates, nest success rates, breeding densities, and daily movements. We also were interested in whether towhees had differences in survival and movement rates between young and mature managed pine stands. We found that survival rates during the …
Leadership In Wolf, Canis Lupus, Packs, L. David Mech
Leadership In Wolf, Canis Lupus, Packs, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
I examine leadership in Wolf (Callis lupus) packs based on published observations and data gathered during summers from 1986 to 1998 studying a free-ranging pack of Wolves on Ellesmere Island that were habituated to my presence. The breeding male tended to initiate activities associated with foraging and travel, and the breeding female to initiate, and predominate in, pup care and protection. However, there was considerable overlap and interaction during these activities such that leadership could be considered a joint function. In packs with multiple breeders, quantitative information about leadership is needed.
Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson
Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
We used simple linear regression to analyze 8-23 years of data on a wolf (Canis lupus) population and human harvest of white-tailed deer (Odocoileus virginianus) bucks in northeastern Minnesota to determine any effects of wolves on buck harvesting. Over the long term, wolves accounted for at least 14-22% inter-year variation in buck harvest in the region, but an unknown amount of variation in hunter effort have obscured any more precise estimate. For part of the area with poorest habitat, we found strong relationships (r2 = 0.66-0.84) between annual wolf numbers and buck harvests from 1988 …

Assessing Factors That May Predispose Minnesota Farms To Wolf Depredations On Cattle, L. David Mech, Elizabeth K. Harper, Thomas J. Meier, William J. Paul
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Wolf (Canis lupus) depredations on livestock cause considerable conflict and expense in Minnesota. Furthermore, claims are made that such depredations are fostered by the type of animal husbandry practiced. Thus, we tried to detect factors that might predispose farms in Minnesota to wolf depredations. We compared results of interviews with 41 cattle farmers experiencing chronic cattle losses to wolves (chronic farms) with results from 41 nearby "matched" farms with no wolf losses to determine farm characteristics or husbandry practices that differed and that therefore might have affected wolf depredations. We also used a Geographic Information System (GIS) to …

The original authors point out that alternative hypotheses were examined and rejected, leaving a violent episode of cannibalism as the most plausible explanation for the remains found at 5MTJOOJO. Dongoske et af. also question many aspects of the osteological, …
Geometric Rule Learning By Clark’S Nutcrackers (Nucifraga Columbiana), Alan Kamil, Juli E. Jones
Geometric Rule Learning By Clark’S Nutcrackers (Nucifraga Columbiana), Alan Kamil, Juli E. Jones
Papers in Behavior in Biological Sciences
Clark’s nutcrackers (Nucifraga columbiana) were trained to search in a location defined by its geometric relationship to 2 landmarks. Two groups were trained to search at different points along the line connecting the landmarks, and 2 groups were trained to find the 3rd point of a triangle, on the basis of either direction or distance from the landmarks. All groups learned and transferred to new interlandmark distances. However, the constant-distance group learned more slowly, searched less accurately, and showed less transfer than the other 3 groups. When tested with new orientations of the landmarks, the birds tended to …
The Cost Of Limited Attention In Blue Jays, Reuven Dukas, Alan Kamil
The Cost Of Limited Attention In Blue Jays, Reuven Dukas, Alan Kamil
Papers in Behavior in Biological Sciences
Experiments with fish and birds suggest that animals are unable to simultaneously allocate sufficient attention to tasks such as the detection of an approaching predator while searching for cryptic prey. We quantified the effects of limited attention on performance in controlled laboratory settings and report here the first direct evidence that attending to a difficult central task simulating foraging deters a bird’s ability to detect a peripheral target, which could be a predator. Our results fill a gap between ecological and neurobiological studies by illustrating that, although attention is an efficient filtering mechanism, limited attention may be a major cause …

Surviving The Flood: Plastron Respiration In The Non-Tracheate Arthropod Phrynus Marginemaculatus (Amblypygi: Arachnida), Eileen Hebets, Reginald F. Chapman
Eileen Hebets Publications
Specimens of Phrynus marginemaculatus can remain responsive when submerged in water for more than 24 hours. Behavioral data indicate that P. marginemaculatus utilizes dissolved oxygen from the surrounding water. Scanning electron miscroscopy and light microscope sections show cuticular modifications for plastron respiration. All previous examples of plastron respiration have involved animals with tracheal systems, but amblypygids respire through the use of two pairs of book lungs. This study provides the first example of plastron respiration not only in the order Amblypygi, but also, in any non-tracheate arthropod.
