Spatial and Temporal Interactions of Sympatric Jaguars (Panthera onca) and Pumas (Puma concolor) in a Neotropical Forest

Abstract We used extensive camera-trap surveys to study interindividual interactions among individually recognizable jaguars (Panthera onca) and plain-colored pumas (Puma concolor). Timed location data from a network of 119 trap stations in the Cockscomb Basin of Belize provide the 1st evidence of interspecific avoidance calibrated against intraspecific interactions among jaguars. Camera trapping has advantages over radiotelemetry in its potential to provide data on the complete array of individuals within the study area. The 23 individually identified male jaguars showed high levels of overlap in ranges, with up to 5 different males captured at the same location in the same month. Low levels of avoidance between individuals and a high flux of individuals contributed to low consistency in home-range ownership over the long term (3 months to 2 years). Jaguars and pumas had similar nocturnal activity schedules. Both species used similar habitats within the Cockscomb Basin, indicated by a high correlation in capture rates per location between species. Apart from their overall spatial similarities, jaguars and pumas avoided using the same location at the same time. This interspecific segregation was detectable over and above the spatial and temporal segregation of individual jaguars.

Heterogeneous capture rates in low density populations and consequences for capture-recapture analysis of camera-trap data

Closed population capture-recapture analysis of camera-trap data has become the conventional method for estimating the abundance of individually recognisable cryptic species living at low densities, such as large felids. Often these estimates are the only information available to guide wildlife managers and conservation policy. Capture probability of the target species using camera traps is commonly heterogeneous and low. Published studies often report overall capture probabilities as low as 0.03 and fail to report on the level of heterogeneity in capture probability. We used simulations to study the effects of low and heterogeneous capture probability on the reliability of abundance estimates using the Mh jack-knife estimator within a closed-population capture-recapture framework. High heterogeneity in capture probability was associated with under- and over-estimates of true abundance. The use of biased abundance estimates could have serious conservation management consequences. We recommend that studies present capture frequencies of all sampled individuals so that policy makers can assess the reliability of the abundance estimates.

Scrape-marking behavior of jaguars (Panthera onca) and pumas (Puma concolor)

Abstract Marking behaviors of jaguars (Panthera onca) and pumas (Puma concolor) were investigated by linking sign from transect surveys to species, sex, and individual detected by camera traps along trails in the Cockscomb Basin Wildlife Sanctuary, Belize. The most commonly encountered big-cat signs were scrape marks. These were produced by cats raking the ground with their feet. Scrapes were associated more strongly with presence of male pumas than with female pumas or jaguars of either sex. Scats found in scrapes were genotyped to species level and indicated that jaguars produced larger scrapes than pumas and that pumas were more likely to scrape with their hind feet than with front feet. Scrapes were spatially clustered along trails, indicating that individuals scrape in response to other scrapes in the same area. High scraping frequencies were not associated with the presence of specific individuals, suggesting that scrape-marking behavior does not signal dominance in this area.

A national survey of computerized decision support systems available to nurses in England

AIM To examine the characteristics of computerized decision support systems (CDSS) currently available to nurses working in the National Health Service (NHS) in England. METHOD A questionnaire survey sent to a stratified random sample of 50% of all NHS care providers (Trusts) in England, asking respondents to provide information on CDSS currently used by nurses. RESULTS Responses were received from 108 of the 277 Trusts included in the sample. Electronic patient record systems were the most common type of CDSS reported by Trusts (n = 61) but they were least likely to have features that have been associated with improved clinical outcomes. CONCLUSIONS The availability of CDSS with features that have been associated with improved patient outcomes for nurses in the NHS in England is limited. There is some evidence that the nature of the Trust affects whether or not nurses have access to CDSS to assist their decision making. IMPLICATIONS FOR NURSING MANAGEMENT The implementation of CDSS is increasing throughout the NHS. Many CDSS are introduced without adequate evidence to support its introduction and there is little evaluation of the benefits once they are implemented. Policy makers and nursing management should consider whether the introduction of CDSS aids nurse decision making and benefits patient outcomes.

Uncertainty and anxiety in the cancer of unknown primary patient journey: a multiperspective qualitative study

Background Patients with cancer of unknown primary (CUP) have metastatic malignant disease without an identifiable primary site; it is the fourth most common cause of cancer death. Objectives To explore patients’ informal and professional carers’ experiences of CUP to inform development of evidence-based, patient-centred care. Methods Qualitative study involving development of multiple exploratory case studies, each comprising a patient and nominated informal and professional carers, with contextual data extracted from medical records. Results 17 CUP patients, 14 informal and 13 professional carers participated in the study. Two inter-related themes distinct to CUP emerged: uncertainty and continuity of care. In the absence of a primary diagnosis, patients and informal carers experienced uncertainty regarding prognosis, possible recurrence and the primarys hereditary potential. Professional carers experienced difficulty communicating uncertainty to patients, ambiguity in deciding optimal treatment plans in the absence of trial data and a test or treat dilemma: when to discontinue seeking the primary and start treatment. Common problems with care continuity were amplified for CUP patients relating to coordination, accountability and timeliness of care. The remit of multidisciplinary teams (MDTs) often excluded CUP, leading to “MDT tennis” where patients were “bounced” between MDTs. Conclusions The experience of those with CUP is distinctive and it can serve to amplify some of the issues encountered by people with cancer. The clinical uncertainties related to CUP compound existing shortcomings in continuity of care, increasing the likelihood of a disrupted patient journey. However, while little can be done to overcome uncertainty, more could be done to address issues regarding continuity of care.

The True NTH Prostate Cancer Survivorship Care programme: Development and evaluation of a model for delivering follow-up care to men with prostate cancer.

42 Background: Increasing use of prostate specific antigen (PSA), improvements in treatment and aging population have led to the escalating incidence of prostate cancer. 5 year survival rate is relatively high and men who have completed treatment require long-term follow-up to detect recurrence or progression of disease, monitor adverse effects of treatment and identify and address psychosocial needs. Studies demonstrate men have a range of unmet physical and psychosocial needs, and health services are struggling to cope with the growing numbers. Changes is critical for long-term sustainability of the health system in many developed nations Methods: This presentation presents a model of follow up care centered on remote surveillance of PSA combined with promoting patient self-management. This initiative is part of the True NTH programme of developments initiated in the UK with funding from Movember Foundation and Prostate Cancer UK. Traditional face to face clinic follow up consultations are replaced with: patient directed individually tailored care and surveillance programme which involves: a 4 hour preparatory patient workshop, remote assessment of unmet needs and symptoms and surveillance of PSA, patient information resources, survivorship care plan, communication of treatment summary and management plan to primary care, and rapid recall system for assessment in secondary care should the need arise. The care programme is mediated through clinician and patient access to an IT portal enabling communication. RESULTS The second part of the presentation will describe the evaluation protocol. A historical cohort design is comparing a group of men receiving clinic follow up care (N = 300) with men enrolled on the care programme (N = 300) in 3 centers. Patient-reported outcomes are collected at baseline, 4 months and 8 months. Health economic evaluation will compare costs of clinic based follow up with those of the care programme from both a health service and patient perspective. CONCLUSIONS The evaluation will generate data on impact, acceptability and cost of this model of follow-up care.

Follow-up care after treatment for prostate cancer: protocol for an evaluation of a nurse-led supported self-management and remote surveillance programme

BackgroundAs more men survive a diagnosis of prostate cancer, alternative models of follow-up care that address men’s enduring unmet needs and are economical to deliver are needed. This paper describes the protocol for an ongoing evaluation of a nurse-led supported self-management and remote surveillance programme implemented within the secondary care setting.Methods/designThe evaluation is taking place within a real clinical setting, comparing the outcomes of men enrolled in the Programme with the outcomes of a pre-service change cohort of men, using a repeated measures design. Men are followed up at four and 8 months post recruitment on a number of outcomes, including quality of life, unmet need, psychological wellbeing and activation for self-management. An embedded health economic analysis and qualitative evaluation of implementation processes are being undertaken.DiscussionThe evaluation will provide important information regarding the effectiveness, cost effectiveness and implementation of an integrated supported self-management follow-up care pathway within secondary care.

Ranging behavior and habitat selection of pacas (Cuniculus paca) in central Belize

Habitat loss and fragmentation present major challenges for wildlife conservation since connectivity between suitable habitat patches is needed for dispersal, allowing for genetic exchange between populations. These exchanges can be particularly important in marginal habitats as they ensure the persistence of populations that are often most vulnerable to natural occurrences or anthropogenic activities. Medium-sized mammals can be particularly susceptible to changes in the landscape and their absence can be an indicator of habitat degradation. In this study, 6 pacas (Cuniculus paca), medium-sized mammals that are an important prey of large felids and a popular game species for hunters in Belize, were radiotracked in the Central Belize Corridor. Home range estimates for these were larger than those documented for pacas inhabiting broadleaf forests of Panama and Costa Rica. When broadleaf habitats were inaccessible due to flooding, pacas selected a savannah habitat with dense vegetation over more open grass savannahs. Knowledge of how pacas and other wildlife use the landscape in the wildlife corridor will allow more effective management by guiding the development of adequate regulations for hunting and resource exploitation.

Spatial and temporal interactions of free-ranging pacas (Cuniculus paca)

Although the paca is the most frequently hunted game species throughout the Neotropics, its behavioral and ecological requirements remain poorly understood. Here, we describe ranging behavior, spatio-temporal intraspecific interactions, and cavity use within a mosaic landscape in Central Belize, based on radio-tracking of four males and two females. This study is the first to investigate social interactions and spatial structure within a paca population in unprotected marginal habitat. We detected extensive home range overlap between males and between sexes. Male-male overlap was less extensive within core areas, while female core ranges were almost entirely occupied by one or more males. On average, pacas used at least six cavities within their home range. The majority of cavities were in the core areas and we did not detect simultaneous co-habitation of the same location. On average, females occupied cavities that were closer together, and closer to water bodies, than those of males. Overall, our study suggests a general tolerance during nocturnal foraging activities, but exclusive use of core areas and associated cavities. The larger ranges of males than females and the extensive overlap between conspecifics suggest a polygamous or promiscuous mating system in this landscape.

Range extension of Northern Naked-tailed Armadillo, Cabassous centralis Miller, 1899 (Mammalia, Cingulata, Chlamyphoridae), in Belize

Little is known about the Northern Naked-tailed Armadillo, Cabassous centralis (Miller, 1899). Here we present a new record of C. centralis in the Maya Mountain Massif of Belize, from camera-trap surveys covering an area of 200 km2 conducted yearly between 2002 and 2017 in lowland tropical broadleaf evergreen forest, and a dead specimen found adjacent to a highway. The record presented constitutes a range expansion of ca 65 km for C. centralis in Belize. This adds valuable data about a species for which the geographic distribution is poorly known.
