The Saurian Psyche Revisted: Lizards In Research, Neil Greenberg Jan 1992

The Saurian Psyche Revisted: Lizards In Research, Neil Greenberg

Neil Greenberg

This essay is intended to guide researchers interested in lizards as prospective experimental models to identify an appropriate species for their research needs and to care for lizards in a manner that will not compromise their utility. Coupled with these is a concern for critical thinking about the ethical dimension of lizard research, one guide for which is to consider the intersection of human needs and lizard needs. Before proceeding further, several arbitrary premises must be made clear: 1. While wholly deserving of study because of their intrinsic interest, I will assume that the lizard research to be undertaken is …


A Pesquisa Urbana No Equador, Fernando Carrión Mena Jan 1988

A Pesquisa Urbana No Equador, Fernando Carrión Mena

Fernando Carrión Mena

É relativamente difícil precisar a origem cronológica de um campo ou área de conhecimento de um país determinado. Ainda mais se tem em conta que tanto a constituição teórica de um campo de conhecimento ultrapassa as fronteiras nacionais, como o objeto empírico de estudo é anterior a sua constitui9ao teórica. Isto é, precede-a e é uma condição necessária porém insuficiente. Para o nosso caso, este objeto é a "cidade", que historicamente existe no Equador, segundo algumas hipóteses desde á conquistam espanhola (Carrión, F. 1986); no entanto um pensamento relativamente consistente sobre ela recém se inicia quando o processo de urbanização …

Ethological Considerations In The Experimental Study Of Lizard Behavior, Neil Greenberg Jan 1978

Ethological Considerations In The Experimental Study Of Lizard Behavior, Neil Greenberg

Neil Greenberg

The importance of an ethological approach to the experimental study of an unfamiliar species is described and several of its problems discussed. The selection of units of behavior is a crucial first step in the development of a behavior inventory. The correlation of a behavioral unit with a particular context is necessary to ascribe function to that to that unit and to develop an ethogram. Methods of studying lizards under controlled conditions are described and discussed. Constraints on behavior that must be considered in an experimental study include the microclimate and its thermal qualities, food and water, shelter utilization, and …
