The ability to recognize and respond to the alarm calls of heterospecifics has previously been described only in species with vocal communication. Here we provide evidence that a non-vocal reptile, the Galápagos marine iguana (Amblyrhynchus cristatus), can eavesdrop on the alarm call of the Galápagos mockingbird (Nesomimus parvulus) and respond with anti-predator behaviour. Eavesdropping on complex heterospecific communications demonstrates a remarkable degree of auditory discrimination in a non-vocal species.

In East Africa fire and grazing by wild and domestic ungulates maintain savannas, and pastoralists historically set fires and herded livestock through the use of temporary corrals called bomas. In recent decades traditional pastoral practices have declined, and this may be affecting biodiversity. We investigated the effects of prescribed fires and bomas on savanna bird communities in East Africa during the first and second dry seasons of the year (respectively before and after the rains that mark the onset of breeding for most birds). We compared abundance, richness, and community composition on 9-ha burned plots, recently abandoned bomas, and control plots in the undisturbed matrix habitat over a 3-year period. Generally, recently burned areas and abandoned bomas attracted greater densities of birds and had different community assemblages than the surrounding matrix. The effects of disturbances were influenced by interactions between primary productivity, represented by the normalized difference vegetation index, and time. Bird densities were highest and a greater proportion of species was observed on burned plots in the months following the fires. Drought conditions equalized bird densities across treatments within 1 year, and individuals from a greater proportion of species were more commonly observed on abandoned bomas. Yearly fluctuations in abundance were less pronounced on bomas than on burns, which indicate that although fire may benefit birds in the short term, bomas may have a more-lasting positive effect and provide resources during droughts. Several Palearctic migrants were attracted to burned plots regardless of rainfall, which indicates continued fire suppression may threaten their already-declining populations. Most notably, the paucity of birds observed on the controls suggests that the current structure of the matrix developed as a result of fire suppression. Traditional pastoralism appears critical to the maintenance of avian diversity in these savannas.

Ethics approval and governance: The study was peer reviewed and registered as a service evaluation with the 2 gether NHS Foundation Trust Research and Development Support Unit and Data Protection Officer. AbstractAim: This study aimed to evaluate an eight-week carers group for people with first episode of psychosis receiving services from the Gloucestershire Recovery in Psychosis Early Intervention Team. Potential benefits for carers were assessed including changes in feelings of stress, isolation, recognition, and of being appreciated and valued.

Four species of biocontrol insects (knapweed root weevil, lesser knapweed flower weevil, spotted knapweed seedhead moth, and bronze knapweed root borer) were released at a diffuse knapweed site located about 10 km east of the Colorado Front Range. Two other biocontrol agents (banded gall fly and knapweed seed head fly) were already present at this site. Densities of rosettes and flowering plants, seedhead production per plant, and seeds per seedhead on mowed and unmowed areas were studied for 5 yr, 1997–2001. Of the six biocontrols, five (Urophora spp., bronze knapweed root borer, knapweed root weevil, and lesser knapweed flower weevil) obtained sizable densities relative to weed abundance. Diffuse knapweed declined from 8.3% in absolute cover in June 2000 to 1.9% by September 2001. Vegetation transects closest to the insect release areas showed the largest declines, with diffuse knapweed disappearing entirely on one transect. In contrast, diffuse knapweed abundance at a nearby prairie increased during the same interval from an absolute cover value of 14.5 to 17%. Seed production of diffuse knapweed on the insect release site declined from nearly 5,000 seeds m−2 in 1997 to less than 100 seeds m−2 in 2001. Lesser knapweed flower weevil larvae appeared responsible for much of the seed reduction, whereas adults of this species were effective in damaging bolting plants. The extent to which grazing removal and individual insect species contributed to this reduction in diffuse knapweed abundance cannot be identified from this study. These results support the contention that a significant reduction in abundance of diffuse knapweed using insects is possible at least in some regions of the western United States.

Therapists have been described as reluctant to work with older people. A legacy of pessimism towards psychotherapy with this group has been traced back to Freud's assertions that older people are no longer educable. It remains unclear to what extent these views continue to influence today's therapists. This study explores the attitudes of trainee clinical psychologists towards psychotherapy with this age group. A cross-sectional postal survey design was used and the data were analyzed using content analysis. Three hundred and seventy-one trainees responded, representing 38% of the total population of trainees in the UK. The majority of the trainees thought that work with older people provided the opportunity to apply psychological knowledge and skills, although therapists needed to respond differently when working with an older person. Factors to take into account included cognitive decline and physical health problems. The trainees described a number of rewards and challenges associated with working with older people. The responses suggest that although a significant minority of trainees continue to hold some negative stereotypes about therapeutic work with older people, positive attitudes are also clearly evident. Further research to explore the attitudes of other healthcare professionals is recommended and the implications for training and supervision are examined.

In this study, the CANSAS was used routinely in a standard AO team, and the finding that over a 6-month period patient-rated unmet need reduced significantly suggests that formal rating of needs assessment may have helped to target care planning effectively. The results suggest that accommodation type and diagnosis may play an important role in the ability of services to effectively meet patient needs, but further work in larger samples is needed to address these questions.

SummaryConsultant psychiatrists are often called to work in teams that are functioning suboptimally. This is a major challenge, both professionally and personally. This article gives advice and strategies for working with struggling teams. It recommends combining objective-, data- and procedure-driven approaches to technical challenges with ‘softer’ person-centred and relational strategies matched to the learning needs of the team.
