The Effect Of Proximity On Landmark Use In Clark’S Nutcrackers, Kristy L. Gould-Beierle, Alan Kamil Jan 1999

The Effect Of Proximity On Landmark Use In Clark’S Nutcrackers, Kristy L. Gould-Beierle, Alan Kamil

Avian Cognition Papers

Clark’s nutcrackers, Nucifraga columbiana, store thousands of pine seeds during the autumn and retrieve them throughout the winter. It has been shown that these birds are able to use visual cues to relocate hidden food in the laboratory. In this set of experiments, we trained three groups of Clark’s nutcrackers to find a hidden food goal that was placed in the same spatial location relative to the testing room. During training, the location of two local cues in relation to the goal differed between the three groups. Group 1 learned the task with the cues closest to the goal, group …


Patterns Of Movement And Orientation During Caching And Recovery By Clark’S Nutcrackers, Nucifraga Columbiana, Alan Kamil, Russell P. Balda, Sally Good Jan 1999

Patterns Of Movement And Orientation During Caching And Recovery By Clark’S Nutcrackers, Nucifraga Columbiana, Alan Kamil, Russell P. Balda, Sally Good

Avian Cognition Papers

Clark’s nutcrackers regularly store large numbers of pine seeds and remember the locations of the cached seeds. Although they are very accurate, they do make some errors during recovery. In an attempt to determine whether any behaviours during caching predicted the occurrence of errors during recovery, we videotaped Clark’s nutcrackers while they cached and recovered seeds under laboratory conditions. We used the videotapes to develop complete, quantitative descriptions of caching and recovery behaviour, with an emphasis on body orientation and directions of movement. During caching, the birds showed the greatest change in their orientation and direction following cache creation. During …


How Do They, Indeed? A Reply To Biegler Et Al., Alan Kamil, Juli E. Jones Jan 1999

How Do They, Indeed? A Reply To Biegler Et Al., Alan Kamil, Juli E. Jones

Avian Cognition Papers

We trained Clark’s nutcrackers, Nucifraga columbiana, to search halfway between two landmarks while varying the distance between the landmarks (Kamil & Jones 1997). We found that the birds learned the problem readily and generalized to novel interlandmark distances within the range of distances used during training. Unlike some other studies in which responses to proportional distance were obtained (e.g. O’Keefe & Burgess 1996; Tommasi et al. 1997), the nutcrackers showed very precise search and maintained this precision during the transfer test. The distributions of digging locations around the central position were concentrated within ±1–2 cm of the central location …

Obtaining And Sampling Of High Quality Energetic-Protein Mixtures (Pottages) Of Tuber-Cereal-Leguminous Bases In The Candelaria Area, Maria Lilian Maldonado Chavez Jan 1999

Obtaining And Sampling Of High Quality Energetic-Protein Mixtures (Pottages) Of Tuber-Cereal-Leguminous Bases In The Candelaria Area, Maria Lilian Maldonado Chavez

Theses and Dissertations

Specially designed foodstuffs destined for children of weaning age in the community of Candelaria were developed and evaluated biologically. These victuals had as bases combinations of tubers-cereals-legumes of high nutritional quality to be implemented in the home. Based on the availability of food and alimentary habits of the region, seven mixtures were formulated of triples and quadruples containing tubers (potato, oca, papaliza, and isano); cereals (rice, wheat, corn, and quinua); and legumes (tarwi, broad bean, and peanut). The cereal-leguminous proportion was maintained as one complement and the addition of the tubers. These mixes were subjected to biological tests, obtaining incremental …

Role Of Farming Women In The Communities Of Puculpala, Llulluchi, And Guzo, Quimiag, Chimborazo, Agusta Filomena Coello Arguello

Theses and Dissertations

In the Ecuadorian society there is a pronounced difference in the distribution of work between men and women. In the Ecuadorian society the man is dominant and the woman is seen as a free form of strenuous and excessive labor, who often goes without pay. The woman herself minimizes her own contribution in the production process, thereby magnifying this culture distinction. The division of work related responsibilities, through gender distinctions, has given women more tasks to complete, in addition to those generally reserved for females (taking care of the children, the animals and various household chores). Women also tend to …


Geographic Variation In Alarm Calls Of Gunnison's Prairie Dogs, C. N. Slobodchikoff, S. H. Ackers, M. Van Ert Dec 1998

Geographic Variation In Alarm Calls Of Gunnison's Prairie Dogs, C. N. Slobodchikoff, S. H. Ackers, M. Van Ert

Communication Skills Collection

Geographic variation in alarm calls of Gunnison's prairie dogs (Cynomys gunnisoni) was analyzed at regional and local scales. Alarm calls in response to a common stimulus (the same human) were recorded at four colonies near Flagstaff, Arizona, and at six sites throughout the southwestern United States. The acoustic structure of calls was analyzed for seven call variables. Regional differences fit the prediction of greater differences with increased geographical separation. Differences between colonies at a local scale were not related to geographical distance, suggesting that local dialects exist within a region. Differences in the level of predation by humans …

5 | The Cave Of The Warrior: A Fourth Millenium Burial In The Judean Desert, Tamar Schick Dec 1998

5 | The Cave Of The Warrior: A Fourth Millenium Burial In The Judean Desert, Tamar Schick

IAA Reports—Monograph Series of the Israel Antiquities Authority

During the survey of the caves in the Jericho area, Cave No. 13 revealed a uniquely well-preserved burial dating to the early 4th millennium BCE, accompanied by burial goods that have rarely been preserved elsewhere, due to the conditions of the cave. The middle-aged male buried together with a unique flint knife anda wooden bow and arrows, among other gifts, was termed the “Warrior”, although he may have been a hunter rather than warrior. Other perishable objects that so rarely survive the millennia include textiles, mats, a basket and leather sandals. A wide range of research topics, analyses and conservation …

Impact Of An Ecological Factor On The Costs Of Resource Acquisition: Fighting And Metabolic Physiology Of Crabs, L. U. Sneddon, F. A. Huntingford, A. C. Taylor Oct 1998

Impact Of An Ecological Factor On The Costs Of Resource Acquisition: Fighting And Metabolic Physiology Of Crabs, L. U. Sneddon, F. A. Huntingford, A. C. Taylor

Ethology Collection

  1. Current game theory models and recent experimental evidence suggests that the strategy an animal adopts in agonistic encounters is determined by individual state. Therefore manipulation of an individual’s state should elicit different behavioural responses. In this paper, mechanisms are examined that underlie state-dependent strategies using Shore Crabs, Carcinus maenas, and how, by altering the environment, behaviour and physiology are affected.
  2. Fights were staged between pairs of male crabs under normoxic and severely hypoxic (< 15 torr) conditions to determine if the metabolic costs of fighting and resource acquisition are affected by water PO2. After fighting, blood and tissue samples from each crab were taken and analysed for metabolites associated with anaerobiosis (L-lactate, glucose and glycogen).
  3. The spectrum …


Assessment Of Side Effects Induced By Injection Of Different Adjuvant/Antigen Combinations In Rabbits And Mice, P.P.A.M. Leenaars, M. A. Koedam, P. W. Wester, V. Baumans, E. Claassen, C. F.M. Hendriksen Oct 1998

Biomedicine and Animal Models in Research Collection

We evaluated the side effects induced by injection of Freund's adjuvant (FA)and alternative adjuvants combined with different antigens. Rabbits and mice were injected subcutaneously, intramuscularly (rabbits) and intraperitoneally (mice)with different adjuvants (FA, Specol, RIBI,TiterMax, Montanide ISA50)in combination with several types of antigens (synthetic peptides, autoantigen, glycolipid, protein, mycoplasma or viruses). The effects of treatment on the animals' well-being were assessed by clinical and behavioural changes (POTand LABORASassays) and gross and histopathological changes. In rabbits, treatment did not appear to induce acute or prolonged pain and distress. Mice showed behavioural changes immediately after (predominantly secondary) immunization. Injection of several adjuvant/antigen mixtures …


Animal Organs In Humans: Uncalculated Risks And Unanswered Questions, Gillian R. Langley, Joyce D'Silva Oct 1998

Animal Organs In Humans: Uncalculated Risks And Unanswered Questions, Gillian R. Langley, Joyce D'Silva

Biomedicine and Animal Models in Research Collection

This report, produced jointly by the British Union for the Abolition of Vivisection and Compassion in World Farming, fills a number of significant gaps in the current debate about xenotransplantation.

In this report we also summarise the ethical and welfare issues concerning experiments on animals for xenotransplant research and their possible use as source animals for organs. Both these aspects are responsible for much pain and distress caused to many animals. We prefer the term “source animals” to “donor animals”, because animals do not choose to donate their organs for xenotransplantation.

Water Conservation In The Las Vegas Valley, Judith M. Keir Oct 1998

Water Conservation In The Las Vegas Valley, Judith M. Keir

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis deals primarily with residential use of water in the Las Vegas Valley, an arid climate located in the Mojave Desert, and whether the education of people living here has any bearing on whether or not they conserve water. Many of the residents of the Las Vegas Valley have moved from other areas of the country, and perhaps are not aware of the fact that there is a limited supply of water available to the Valley. I believe that people are not necessarily wasteful, and that they would want to conserve water, if they were aware that conservation and …

Evolution And Animal Welfare, Marian Stamp Dawkins Sep 1998

Evolution And Animal Welfare, Marian Stamp Dawkins

Assessment of Animal Welfare Collection

Animal welfare is a topic often thought to reside outside mainstream biology. The complexity of the methods used to assess welfare (such as health, physiology, immunological state, and behavior) require an understanding of a wide range of biological phenomena. Furthermore, the "welfare" of an animal provides a framework in which a diversity of its responses can be understood as fitness-enhancing mechanisms. Different methods for assessing animal welfare are discussed, with particular emphasis on the role of an animal's own choices and reinforcement mechanisms. No part of biology is as yet able to explain consciousness, but by confronting the possibility that …

Feather Evidence Helps Clarify Locality Of Anthropological Artifacts In The Museum Of Mankind, Carla J. Dove Sep 1998

Feather Evidence Helps Clarify Locality Of Anthropological Artifacts In The Museum Of Mankind, Carla J. Dove

Pacific Studies

Species of birds used on ethnographic artifacts collected during the eighteenth century and stored at the Museum of Mankind (British Museum) were identified by using microscopic and whole-feather characters. One of the objects (VAN 345), labeled as having been collected on Vancouver’s voyage to Tahiti, was a feather pendant made of long strands of chicken feathers with small red feathers at the base. The small red feathers were examined microscopically, compared with museum study skins of all possible species, and identified as Vestiaria coccinea (‘I‘iwi). Since this species is known only from the Hawaiian Archipelago, it was determined that the …
