Eliciting conditioned taste aversion in lizards: Live toxic prey are more effective than scent and taste cues alone.

Conditioned taste aversion (CTA) is an adaptive learning mechanism whereby a consumer associates the taste of a certain food with symptoms caused by a toxic substance, and thereafter avoids eating that type of food. Recently, wildlife researchers have employed CTA to discourage native fauna from ingesting toxic cane toads (Rhinella marina), a species that is invading tropical Australia. In this paper, we compare the results of 2 sets of CTA trials on large varanid lizards ("goannas," Varanus panoptes).

Engagement and opportunity in clinical learning: findings from a case study in primary care.

Background: This article explores in a primary care setting how clinical learning occurs across a range of professional groups and levels of learner experience, both undergraduate and postgraduate.

Aim: To explore how clinical learning occurs in a primary care workplace from a socio-cultural perspective.

Method: A single case study approach using interview data from 33 participants and strengthened through direct and indirect observations and documentary evidence.

Portfolio use in general practice vocational training: a survey of GP registrars.

Background: Portfolios are increasingly advocated in medical education. Qualitative studies have suggested their value in stimulating experiential learning, promoting deep learning and encouraging reflection. This study explored the use of educational portfolios in reflective learning by general practice (GP) registrars in Yorkshire, England.
