Habitat quality, as indexed by the reproductive success of individuals, can greatly influence population growth, especially for rare species near the limits of their range. Along the Pacific coast, the Snowy Plover (Charadrius alexandrinus nivosus) is a threatened species that, in recent years, has been breeding on both riverine gravel bars and ocean beaches in northern California. From 2001 to 2009, we compared the habitat characteristics, breeding phenology, reproductive success, and abundance of Western Snowy Plovers occupying these two habitats. Similar percentages of yearling and adult plovers returned to gravel bars and beaches, but plovers breeding on gravel bars arrived and initiated first clutches 2–3 weeks later than those breeding on beaches. Despite this delay, however, the mean annual fledging success of plovers on gravel bars (1.4 ± 0.4 [SD]) was double that on beaches (0.7 ± 0.3). Differences in cumulative reproductive success produced a stronger pattern. By their sixth year, males on gravel bars had fledged 14.5 ± 2.1 chicks, more than four times the number of young fledged by males on beaches (3.3 ± 3.1). Over 9 years, local population size decreased by about 75%, coincident with a shift in breeding distribution away from high‐quality gravel bars to ocean beaches. This unexpected population decline and shift to poorer quality beaches may have been related to occasional low survival of plovers that over‐winter exclusively on beaches in our study area. Consistently low productivity of plovers breeding on ocean beaches suggests the need for intensified management to ameliorate the negative impacts of predation and human activity on the recovery of this population.
Alcohol and other drug use is a serious problem among American Indian and Alaska Native women. However, information about their needs for treatment is lacking. In response, a study was conducted to document the life experiences and perceived recovery needs of American Indian and Alaska Native women at nine treatment centers nationwide. The data show that most of these women have experienced various forms of abuse and neglect from childhood into adulthood and have been exposed to alcohol and other drugs from an early point in their lives. Most of these women have made multiple attempts to recover from their addictions, often for the sake of their children. The information derived from this study can be used as the foundation for further research about the treatment needs of American Indian and Alaska Native women.
Analysis of the 1992 Niger Demographic and Health Survey showed that although roughly two-thirds of both polygamous and monogamous women approve of birth control, polygamous wives are less likely than monogamous wives to discuss family size or birth control with their husband or to plan on using birth control. The study suggests that characteristics of polygamous couples have caused polygamous women to be more resistant to birth control use than monogamous women. The polygamous women tended to be married to older men who had not gone to primary school and who desired more children than monogamous husbands. The influence of marital structure is not significantly associated with intention to use birth control when the husband's age and the wife's ideal number of children were controlled for in the multivariate logistic regression model suggesting that background social factors may be more influential. In fact, educational level and age at first marriage were significantly associated with attitudes towards birth control and also with marital structure.
In recent years imprisonment has been used increasingly for a wide range of nonviolent and petty offenses committed by women. Among incarcerated women, particularly those who are pregnant or parenting, substance use and its deleterious consequences are often exacerbated by imprisonment. Women who have been identified as chemically dependent are also at high risk for losing custody of their children. In California, the Options for Recovery (OFR) treatment program provided an alternative to incarceration or relinquishment of custody of children for chemically dependent pregnant and parenting women. This three-year pilot project offered alcohol and other drug abuse treatment and case management to these women, and included special training and recruitment of foster parents for their children. Findings from a three-year, multimethod evaluation study showed that women who were mandated to OFR treatment programs were more likely to successfully complete treatment than women who had enrolled in OFR voluntarily. An economic analysis of the costs associated with women in OFR compared with the combined costs of incarceration and alcohol and other drug abuse treatment produced a ratio in favor of OFR. Additionally, some innovative service alternatives for women mandated to treatment were developed during the project. The impact of such changes have implications for improving women's and family health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
