Sociality Increases Juvenile Survival After A Catastrophic Event In The Feral Horse (Equus Caballus), Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein

In several social species, adult associations have been linked to individual fitness. Less is known about offspring associations and the mechanisms by which they may influence fitness. We investigate the effects of sociality on juvenile survival in feral horses (Equus caballus). We use foal degree (number of associates) and foal weight (number of interactions) to assess sociality’s importance to foal survival of a catastrophic event, the gathering and removal of 40% of the horse population. We found that 1) foal degree was a better predictor of foal survival than was foal weight; 2) following the gather, foals with access to …
Linking Social Behavior And Stress Physiology In Feral Mares (Equus Caballus): Group Transfers Elevate Fecal Cortisol Levels, Cassandra M.V. Nuñez, James S. Adelman, Jessica Smith, Laurence Gesquiere, Daniel I. Rubenstein

Feral horses (Equus caballus) have a complex social structure, the stability of which is important to their overall health. Behavioral and demographic research has shown that decreases in group (or band) stability reduce female fitness, but the potential effects on the physiological stress response have not been demonstrated. To fully understand how band stability affects group-member fitness, we need to understand not only behavioral and demographic, but also physiological consequences of decreases to that stability. We studied group changes in feral mares (an activity that induces instability, including both male and female aggression) on Shackleford Banks, NC. We found that …

The Youth Expanded Food and Nutrition Education Program (EFNEP) is one of the United States Department of Agriculture's hallmark nutrition education programs for limited-resource youth. The objective of this study was to gather opinions from experts in EFNEP and related content areas to identify costs, effects (impacts), and related instruments to develop a cost-effectiveness model (instrument) for youth EFNEP, which does not exist. A cost-effectiveness model determines the economic or financial cost of producing an impact. The findings highlight several challenges in identifying inputs through consensus and provide a roadmap for the creation of a model that can be adopted …

Rural and agricultural history provide their readers different perspectives on the ways in which the countryside has changed over the course of American history. Rural history approaches the question of change from the perspective of communities and families, while agricultural history generally eschews the social perspective for issues of crop production. Such is the case of two recent and important books in rural and agricultural history, Hal Barron's Mixed Harvest: The Second Great Transformationin the Rural North, 1870-1930 and Steven Stoll's The Fruits of Natural Advantage: The Making of the Industrial Countryside in California. While both authors are intimately concerned …

Illinois' agricultural history is long and complex. Illinois' first settlers, the Native Americans, practiced hunting, gathering, and fishing and made use of the resources of the woods and prairies. By the tenth century, Native Americans combined men's hunting with women's agricultural activities to meet the needs of their communities. The earliest crop Native American women cultivated was corn, imported to Illinois from the Southwest.

Chivalry In Pholcid Spiders Revisited, Julie A. Blanchong, Michael S. Summerfield, Mary A. Popson, Elizabeth M. Jakob

Cohabiting pairs of adult spiders are likely to interact over prey, and the outcome of these interactions is likely to affect the reproductive success of both individuals. In two species of pholcid spiders, previous workers reported the occurrence of "chivalrous" behavior, in which males cede prey to females. We looked for the occurrence of chivalrous behavior in another pholcid spider, Holocnemus pluchei. Pairs of spiders were placed on a web and left overnight without prey. A housefly was then introduced onto the web equidistant from the spiders, and subsequent interactions were noted on audiotape. We found no evidence of chivalry …

Acoustical characteristics of vocalizations of sows, piglets, and nursery pigs under selected husbandry practices were analyzed with a digital signal processing system. The duration (D) and major energy-resonance frequency (P) for each call were determined as follows: a) processing of piglets (D = 0.81 s and f* = 3 700 Hz); b) food anticipation of breeding-gestation sows (2.50 s and 3 000 Hz); c) isolation of piglet (0.34 s and 500, 3 500 Hz); d) startling of nursery pigs (0.29 s and 900 Hz); e) sows in heat (3.07 s and 1 375 Hz); f) farrowing (0.10 s and 3 …
