Factors limiting the colonization success of an introduced exotic fish (Carassius auratus)Richardson, Michael John January 1996 (has links)
The goldfish (Carassius auratus) is a hardy exotic species that have established sporadically distributed feral populations throughout North America. In one shallow seasonally anoxic pond goldfish formed a large stunted population of 15-17,000 ind ha$ sp{-1}$, with 53% being small young of the year. Goldfish were predominantly benthic herbivores with little diet overlap with resident red-spotted newts (Notapthalmus v. viredescens). Thus in relatively simple systems lacking fish predators goldfish can be very successful. However in systems with a complex native fish community, goldfish have had less success in colonizing. This could be related to an inability of goldfish to cope with native predators. / Tests for assortative shoaling between brown and gold coloured morphs showed that gold coloured fish exhibited no colour based assortive shoaling, while brown fish showed slight but significant colour preferences for like-coloured fish. This level of shoaling preference did not improve after visual exposure or interaction with native predators, indicating that goldfish showed limited behaviourial responses to predators, and that they were unable to modify their response to a predation threat. Further trials allowing goldfish to interact with either pike (Esox lucius) or bass (Ambloplites rupestris), in both single species groups of predator-naive goldfish, and mixed species conditions of goldfish with predator-experience minnows, showed that goldfish did not alter their behaviour in the presence of minnows (Pimephales notatus) when the predators were not present. However, with the predators present goldfish altered their activities to a more minnow-like pattern and showed a significant improvement in anti-predator behaviour. This improved behaviour continued by goldfish when they were retested on their own, indicating that the goldfish were reacting to the predator and not the minnows. Goldfish colonization may therefore be limited not so much by predation or competition from native cyprinids, but more by the absence/presence of a suitable, native, predator-experienced fish from which to copy the appropriate anti-predator behaviours.

A reexamination of the adoption of the bow and arrow in the eastern woodlandsMeece, Jamie S. January 2007 (has links)
This thesis reexamines the adoption of the bow and arrow in the Eastern Woodlands. Archaeologists have usually relied on the size and shape of projectile points to help them determine when the bow and arrow was adopted, since the other parts of this complex system (e.g., the wooden bows and arrow shafts) do not survive well in the Eastern Woodlands. The current belief is that the bow and arrow was introduced during the Late Woodland period (AD 500) in the Eastern Woodlands. This is based on the wide spread use of small stone projectile points and on their continued use up to European contact. However, this small point technology was actually established during the Late Archaic period (2000 BC). A wide range of evidence is presented in this thesis that shows that the bow and arrow may have been adopted during the Late Archaic period and was well established during the Middle Woodland period (AD 100) in several Eastern Woodland states. / Department of Anthropology

Casting eastern North American point typesSchwartz, Raphael Lee January 1977 (has links)
The purpose of this project is to demonstrate a technique in producing reproductions of points in acrylic. Based on an article by John R. Rohner in Volume 35 of American Antiquity entitled, "Techniques of Making Plastic Casts of Artifacts 'From Permanent Molds".The project expanded on this idea, and added different steps in order to simplify the procedure. Completed, the finished points will be used as teaching aids.

The process of transforming human rights practices in Latin America : NGOs and their quest to develop international human rights normsBaltodano Egner, Charlotte January 2002 (has links)
International lawyers are increasingly interested in studying NGOs ("NGOs") and their influence on state behavior, but few have studied the impact that domestic NGOs can have on transforming and generating international norms. This paper explores the links between Latin American NGOs and their aim of changing international norms into more effective instruments against systematic violations of human rights by states. I will aim to articulate the stages of the processes that NGOs go through to change state behavior. / I decided to write about NGOs and changes to human rights norms because I have dedicated most of my life to trying to eliminate human rights violations in Latin America. To the detractors that insist that such attempts are futile, I would respond that every effort one can contribute to the human rights movement is one step towards the goal of transforming beliefs and principles into real changes to state practices.

The human rights of the child : the case of street children in Central AmericaBrom, Charlotte January 2002 (has links)
Street children in Central America are largely denied protection of their human rights. They live in difficult situations of poverty, inappropriate work and neglect, and thus are not able to enjoy most of their rights and basic needs. / The international framework for children's human rights law, composed primarily of the Convention on the Rights of the Child and the principles inherent to it, can be described as based on a doctrine of integral protection, a notion developed primarily by Central American legal scholars. At the same time, however, most Central American states ignore their obligations to conform their domestic legislation to these standards. / This thesis is meant to provide Central American countries with guidelines captured by a model referred to as UPPP2. Its main objective is for States to acknowledge that the plight of street children needs to be understood; prevented by adequate domestic legislation; and requires protection by effective implementation and provision of justice.
