Partial migration is a common life-history strategy among ungulates living in seasonal environments. The decision to migrate or remain on a seasonal range may be influenced strongly by access to high-quality habitat. We evaluated the influence of access to winter habitat of high quality on the probability of a female white-tailed deer (Odocoileus virginianus) migrating to a separate summer range and the effects of this decision on survival. We hypothesized that deer with home ranges of low quality in winter would have a high probability of migrating, and that survival of an individual in winter would be influenced by the quality of their home range in winter. We radiocollared 67 female white-tailed deer in 2012 and 2013 in eastern Washington, United States. We estimated home range size in winter using a kernel density estimator; we assumed the size of the home range was inversely proportional to its quality and the proportion of crop land within the home range was proportional to its quality. Odds of migrating from winter ranges increased by 3.1 per unit increase in home range size and decreased by 0.29 per unit increase in the proportion of crop land within a home range. Annual survival rate for migrants was 0.85 (SD = 0.05) and 0.84 (SD = 0.09) for residents. Our finding that an individual with a low-quality home range in winter is likely to migrate to a separate summer range accords with the hypothesis that competition for a limited amount of home ranges of high quality should result in residents having home ranges of higher quality than migrants in populations experiencing density dependence. We hypothesize that density-dependent competition for high-quality home ranges in winter may play a leading role in the selection of migration strategy by female white-tailed deer.

Purpose: This article reports the results of a randomized,controlledevaluationofPartnersinCaregivingin a Special Care Environment, an intervention designed to improve communication and cooperation between staffandfamiliesofresidentsinnursinghomedementia programs. Design and Methods: Participants included 388 family members and 384 nursing staff members recruited from 20 nursing homes, randomly assigned to treatment and control conditions. Project staff conducted training sessions on communication and conflict-resolution techniques with two groups at the intervention sites: staff and residents’ family members, followed by a joint meeting with facility administrators. Results: Families, staff, residents, and facility programs in the intervention facilities all demonstrated positive outcomes from program participation. Families experienced significant improvement in communicating with staff and in staff behaviors toward them, and spouses of residents increased their care involvement. Staff reported reduced conflict with families and reduced depression; burnout for nurses increased for individuals in the control group but not those in the treatment group. Behavioral symptoms decreased for residents, and facilities implemented more family-focused programs. Implications: Effective staff and family partnerships are critical in caring forresidentswithdementia.ThePartnersinCaregiving inaSpecialCareEnvironmentprogramisanevidencebased intervention that enables these partnerships to develop and thrive, translating into improved experiences for residents, families, and staff.
