Food and Nutrition Security - meanings and appropriations from the civil society segment of the National Council for Food and Nutrition Security

The huge transformations that occurred in the last two decades had impacts on the standards of food production and consumption, and determined a wider discussion in Brazil about the theme of food and nutrition security. It has also expanded the scope of it, which now considers nourishing aspects regarding the entire population and not only its most vulnerable segments. This research identified different meanings present in the speech about food and nutrition security, terms incorporated by movements and civil society organizations that were represented at the National Council for Food and Nutrition Security (administration 2004-2007). Thematic appropriation could be observed in the following directions: a) privileging the interaction between thematic fields from both production and consumption spheres; b) strengthening the idea of nutrition as a human right; c) including an ethical goal to the country's development; d) development of an intra and intersectorial perspective; e) identifying the need of dialogic and freeing educational processes.

JUVENILE RECRUITMENT, EARLY GROWTH, AND MORPHOLOGICAL VARIATION IN THE ENDANGERED SANTA CATALINA ISLAND RATTLESNAKE, CROTALUS CATALINENSIS

Life-history information constitutes the raw data for building population models used in species conservation. We provide life-history data for the endangered Santa Catalina Island Rattlesnake, Crotalus catalinensis. We use data from 277 observations of C. catalinensis made between 2002 and 2011 on the island. Mean snout-vent length (SVL) of adult C. catalinensis was 643 mm for males and 631 mm for females; the difference was not significant. The degree of sexual size dimorphism (SSD; using SVL) was -0.02. However, sexes were dimorphic in total length ( SVL + tail length), relative tail length, and stoutness. Juvenile recruitment occurs during late-summer. In their first year of life, juveniles seem to grow at a rate of about 1.7 cm/mo. Females seem to become mature around 570 mm SVL, probably in the year when they become 2 y old. Scattered literature data corroborates the time of juvenile recruitment described herein. Growth in C. catalinensis seems to be slower than that of C. ruber, its sister taxa, but similar to other rattlesnakes.
