Abstract
The European Union has made extensive biodiversity conservation efforts with the Habitats and Birds Directives and with the establishment of the Natura 2000 network of protected areas, one of the largest networks of conservation areas worldwide. We performed a gap analysis of the entire Natura 2000 system plus national protected areas and all terrestrial vertebrates (freshwater fish excluded). We also evaluated the level of connectivity of both systems, providing therefore a first estimate of the functionality of the Natura 2000 system as an effective network of protected areas. Together national protected areas and the Natura 2000 network covered more than one-third of the European Union. National protected areas did not offer protection to 13 total gap species (i.e., species not covered by any protected area) or to almost 300 partial gap species (i.e., species whose representation target is not met). Together the Natura 2000 network and national protected areas left 1 total gap species and 121 partial gap species unprotected. The terrestrial vertebrates listed in the Habitats and Birds Directives were relatively well covered (especially birds), and overall connectivity was improved considerably by Natura 2000 sites that act as stepping stones between national protected areas. Overall, we found that the Natura 2000 network represents at continental level an important network of protected areas that acts as a good complement to existing national protected areas. However, a number of problems remain that are mainly linked to the criteria used to list the species in the Habitats and Birds Directives. The European Commission initiated in 2014 a process aimed at assessing the importance of the Birds and Habitats Directives for biodiversity conservation. Our results contribute to this assessment and suggest the system is largely effective for terrestrial vertebrates but would benefit from further updating of the species lists and field management.

Abstract
Long-term studies have revealed population declines in fishes, amphibians, reptiles, birds and mammals. In birds, and particularly amphibians, these declines are a global phenomenon whose causes are often unclear. Among reptiles, snakes are top predators and therefore a decline in their numbers may have serious consequences for the functioning of many ecosystems. Our results show that, of 17 snake populations (eight species) from the UK, France, Italy, Nigeria and Australia, 11 have declined sharply over the same relatively short period of time with five remaining stable and one showing signs of a marginal increase. Although the causes of these declines are currently unknown, we suspect that they are multi-faceted (such as habitat quality deterioration, prey availability), and with a common cause, e.g. global climate change, at their root.

Abstract
Factors affecting the distribution of species in fragmented landscapes, and their relative importance, are often unclear. Few studies have deliberately compared various hypotheses in relatively controlled conditions. Moreover, most studies to date have not incorporated false absences in their modeling. Following a multiple hypotheses testing framework, we tested the relative role of landscape structure, patch and neighborhood configuration, patch internal structure, presence or absence of predators, and presence or absence and abundance of potential competitor species on the occupancy patterns of three rodent species ( Myodes glareolus (Schreber, 1780), Apodemus flavicollis (Melchior, 1834), Apodemus sylvaticus (L., 1758)) in a highly fragmented landscape in Tuscany, central Italy. Distribution patterns and occupancy dynamics of the three rodent species were affected by patch and patch neighborhood characteristics, as well as the vicinity of other patches occupied by the species. However, we found no relevant effect of the surrounding landscape structure, patch internal structure, predator patch use, and abundance or distribution of potential competitor species. The observed spatial correlation between populations and the evidence of colonization or extinction events suggest that a metapopulation approach could provide a good framework for understanding the long-term dynamics of these populations.

Abstract
The availability of volunteers for research on antidepressant medications raises questions about similarities between symptomatic volunteers and clinic patients. Volunteers accepted for a depression study and patients with major depressive disorder have been shown to have some similarities with regard to depressive symptoms and responses to treatment. However, it is unknown whether the population from which volunteers are drawn differs from the patient population in other ways that affect the generalizability of research findings. Respondents to newspaper advertisements for symptomatic volunteers and new clinic patients at a university-based, outpatient psychiatric facility received the Beck Depression Inventory, the Millon Behavioral Health Inventory and a questionnaire developed for the study. The first 30 respondents in each group with a Beck Depression Inventory score of at least 10 constituted the sample. No significant differences (p less than 0.05) between the groups were found on demographics, coping styles with help givers, perceptions of psychosocial stress, or overall depression severity. However, volunteers were sadder, more discouraged, and less interested in others than clinic patients. Symptomatic volunteers also more frequently reported financial concerns as an important factor in the decision about seeking help. However, they reported the desire to find effective treatment as the primary factor in the decision. Clinic patients, on the other hand, cited being referred as primary in the seeking help decision, with the desire for effective treatment being secondary. Results of this study suggest that volunteers for drug research are similar in important ways to persons who seek treatment for similar symptomatology. They also suggest that perception of need for treatment may be affected by the strength of specific depressive symptoms.

Abstract
Seventy-seven smokers quit smoking and were randomly assigned to a 3 x 2 design contrasting instructions (told received nicotine gum versus told received placebo gum versus not told which gum received) and receipt of nicotine (received nicotine gum versus received placebo gum). Both being told one received nicotine and actual receipt of nicotine increased the number of days abstinent and decreased the number of cigarettes smoked (P less than 0.05). Receipt of nicotine but not instructions appeared to influence withdrawal (P = 0.06). Instructions but not receipt of nicotine appeared to influence craving (P = 0.08), gum self-administration (P = 0.06) and reported helpfulness of the gum (P = 0.02). Neither nicotine nor instructions influenced side-effects. Instructions and nicotine interacted in several ways. For example, nicotine appeared to increase abstinence in the blind and told placebo conditions more than in the told nicotine condition (P less than 0.05). Our results suggest the effects of instructions and nicotine 1) are not mutually exclusive, 2) vary across dependent variables and 3) can interact such that instructions modify the therapeutic and subjective effects of nicotine.
