Regional specialization in pyramidal cell structure in the visual cortex of the galago: An intracellular injection study of striate and extrastriate areas with comparative notes on New World and Old World monkeys

Recent studies have revealed marked differences in the basal dendritic structure of layer III pyramidal cells in the cerebral cortex of adult simian primates. In particular, there is a consistent trend for pyramidal cells of increasing complexity with anterior progression through occipitotemporal cortical visual areas. These differences in pyramidal cell structure, and their systematic nature, are believed to be important for specialized aspects of visual processing within, and between, cortical areas. However, it remains unknown whether this regional specialization in the pyramidal cell phenotype is unique to simians, is unique to primates in general or is widespread amongst mammalian species. In the present study we investigated pyramidal cell structure in the prosimian galago (Otolemur garnetti). We found, as in simians, that the basal dendritic arbors of pyramidal cells differed between cortical areas. More specifically, pyramidal cells became progressively more spinous through the primary (V1), second (V2), dorsolateral (DL) and inferotemporal ( IT) visual areas. Moreover, pyramidal neurons in V1 of the galago are remarkably similar to those in other primate species, in spite of large differences in the sizes of this area. In contrast, pyramidal cells in inferotemporal cortex are quite variable among primate species. These data suggest that regional specialization in pyramidal cell phenotype was a likely feature of cortex in a common ancestor of simian and prosimian primates, but the degree of specialization varies between species.

Specialization of pyramidal cell structure in the visual areas V1, V2 and V3 of the South American rodent, Dasyprocta primnolopha

Marked phenotypic variation has been reported in pyramidal cells in the primate cerebral cortex. These extent and systematic nature of these specializations suggest that they are important for specialized aspects of cortical processing. However, it remains unknown as to whether regional variations in the pyramidal cell phenotype are unique to primates or if they are widespread amongst mammalian species. In the present study we determined the receptive fields of neurons in striate and extrastriate visual cortex, and quantified pyramidal cell structure in these cortical regions, in the diurnal, large-brained, South American rodent Dasyprocta primnolopha. We found evidence for a first, second and third visual area (V1, V2 and V3, respectively) forming a lateral progression from the occipital pole to the temporal pole. Pyramidal cell structure became increasingly more complex through these areas, suggesting that regional specialization in pyramidal cell phenotype is not restricted to primates. However, cells in V1, V2 and V3 of the agouti were considerably more spinous than their counterparts in primates, suggesting different evolutionary and developmental influences may act on cortical microcircuitry in rodents and primates.

Host-specificity of monogenean (platyhelminth) parasites: a role for anterior adhesive areas?

Monogeneans (flatworms) are among the most host-specific of parasites in general and may be the most host-specific of all fish parasites. Specificity, in terms of a restricted spatial distribution within an environment, is not unique to parasites and is displayed by some fungi, insects, birds, symbionts and pelagic larvae of free-living marine invertebrates. The nature of cues, how habitats are recognised and how interactions between partners are mediated and maintained is of interest across these diverse associations. We review some experiments that demonstrate important factors that contribute to host-specificity at the level of infective stages (larvae of oviparous monogeneans; juveniles of viviparous gyrodactylids) and adult parasites. Recent research on immune responses by fish to monogenean infections is considered. We emphasise the critical importance of host epidermis to the Monogenea. Monogeneans live on host epidermis, they live in its products (e.g. mucus), monopisthocotyleans feed on it, some of its products are attractants and it may be an inhospitable surface because of its immunological activity. We focus attention on fish but reference is made to amphibian hosts. We develop the concept for a potential role in host-speciality by the anterior adhesive areas, either the specialised tegument and/or anterior secretions produced by monogeneans for temporary but firm attachment during locomotion on host epithelial surfaces. Initial contact between the anterior adhesive areas of infective stages and host epidermis may serve two important purposes. (1) Appropriate sense organs or receptors on the parasite interact with a specific chemical or chemicals or with surface structures on host epidermis. (2) A specific but instant recognition or reaction occurs between component(s) of host mucus and the adhesive(s) secreted by monogeneans. The chemical composition of fish skin is known to be species-specific and our preliminary analysis of the chemistry of some monogenean adhesives indicates they are novel proteins that display some differences between parasite families and species.

Establishment of a reedbed within a created surface water fed wetland nature reserve

In the early 1990's, outline designs for two wetland nature reserves were being prepared: the Teeside International Nature Reserve (TINR) and the Cardiff Bay Barrage Environmental Compensation Measures at Redwick, Gwent. The initial design for both proposals identified reedbed as a desirable habitat for establishment. The initial design works identified the importance of reedbed evapotranspiration [ET(Reed)] within the water budget, however, literature searches identified a paucity of information on this parameter. Field experiments for the measurement of ET(Reed) from Phragmites australis are described for three sites distributed across England and Wales. Reference Crop Evapotranspiration (ETo) was calculated using techniques recommended by the Food and Agriculture Organisation. A technique for the calculation of a reedbed crop coefficient [Kc(Reed)[, from ET(Reed) and ETo data is discussed. Kc(Reed) values produced in the project were found to be similar to those developed previously in continental Europe. Mean monthly and crop development stage Kc(Reed) values are presented which are applicable in the UK and possibly worldwide. A conceptual hydrological model of surface water fed reedbed systems is developed, and used to calculate the hydrological sustainability of reedbed creation areas in the UK. Finally, the water budget model is verified using data from a small clay catchment located on the TINR. In addition, a methodology is developed for the hydrological design of surface water fed reedbed systems, and recommendations required for the feasibility, design and establishment stage of reedbed creation sites. Further research needs are also identified.

Community involvement in urban nature conservation : case studies of the Urban Wildlife Group 1980-85

The effectiveness of the strategies employed by the Urban Wildlife Group (a voluntary conservation organisation) to provide and manage three urban nature parks has been evaluated, using a multiple methods methodology. Where the level of community interest and commitment to a project is high, the utilisation of the community nature park strategy (to maximise benefits to UWG and the community) is warranted. Where the level of interest and commitment of the local community is low, a strategy designed to encourage limited involvement of the community is most effective and efficient. The campaign strategy, whereby the community and UWG take direct action to oppose a threat of undesirable development on a nature park, is assessed to be a sub-strategy, rather than a strategy in its own right. Questionnaire surveys and observations studies have revealed that urban people appreciate and indeed demand access to nature parks in urban areas, which have similar amenity value to that provided by countryside recreation sites. Urban nature parks are valued for their natural character, natural features (trees, wild flowers) peace and quiet, wildlife and openness. People use these sites for a mixture of informal and mainly passive activities, such as walking and dog walking. They appear to be of particular value to children for physical and imaginative play. The exact input of time and resources that UWG has committed to the projects has depended on the level of input of the local authority. The evidence indicates that the necessary technical expertise needed to produce and manage urban nature parks, using a user-oriented approach is not adequately provided by local authorities. The methods used in this research are presented as an `evaluation kit' that may be used by practitioners and researchers to evaluate the effectiveness of a wide range of different open spaces and the strategies employed to provide and manage them.

The Role of the FIU Nature Preserve in Promoting Physical Activity

The FIU Nature Preserve was established over thirty-five years ago as an environmental educational center where visitors could experience and learn about local south Florida ecosystems and organisms. This 16-acre facility in the heart of the MMC campus has recently become a popular outdoor fitness destination since the inauguration of a jogging path during Fall 2013. This study set out to quantify how many people visit the FIU Nature Preserve annually, who they are, and what they are doing there. It is also assessing the effect of the FIU Nature Preserve on the overall health of the university community since studies have found that physical activity and contact with nature are positively associated with good health. A pilot was completed during Fall 2014, and the study is on track to finish March 22, 2015. To measure current visitation, two types of surveys were done on seven days across seven weeks during the spring of 2015, visitation counts and in-person surveys. By understanding the reasons and ways people discover and embark on regular use of natural areas, land managers and policy makers can make more informed decisions. As human population and development continue to grow, new ways to integrate natural areas into our urban environment and our lifestyles must be found. In this way, natural resource conservation could be championed as a way for communities to promote physical activity and good health beyond simply using their intrinsic value.

Fossil associations from the middle and upper Eocene strata of the Pamplona Basin and surrounding areas (Navarre, western Pyrenees)

Fossil associations from the middle and upper Eocene (Bartonian and Priabonian) sedimentary succession of the Pamplona Basin are described. This succession was accumulated in the western part of the South Pyrenean peripheral foreland basin and extends from deep-marine turbiditic (Ezkaba Sandstone Formation) to deltaic (Pamplona Marl, Ardanatz Sandstone and Ilundain Marl formations) and marginal marine deposits (Gendulain Formation). The micropalaeontological content is high. It is dominated by foraminifera, and common ostracods and other microfossils are also present. The fossil ichnoasssemblages include at least 23 ichnogenera and 28 ichnospecies indicative of Nereites, Cruziana, Glossifungites and ?Scoyenia-Mermia ichnofacies. Body macrofossils of 78 taxa corresponding to macroforaminifera, sponges, corals, bryozoans, brachiopods, annelids, molluscs, arthropods, echinoderms and vertebrates have been identified. Both the number of ichnotaxa and of species (e. g. bryozoans, molluscs and condrichthyans) may be considerably higher. Body fossil assemblages are comparable to those from the Eocene of the Nord Pyrenean area (Basque Coast), and also to those from the Eocene of the west-central and eastern part of South Pyrenean area (Aragon and Catalonia). At the European scale, the molluscs assemblages seem endemic from the Pyrenean area, although several Tethyan (Italy and Alps) and Northern elements (Paris basin and Normandy) have been recorded. Palaeontological data of studied sedimentary units fit well with the shallowing process that throughout the middle and late Eocene occurs in the area, according to the sedimentological and stratigraphical data.

Understanding Suicide and Help-seeking in Urban and Rural Areas in Northern Ireland

Funded by HSC R&D Division, Public Health Agency Why did we start? Most people who complete suicide are in contact with their family doctors or other services in the months prior to death. A better understanding of the nature of these contacts and the various pathways experienced by suicidal people should reveal the gaps and barriers to effective service provision. We also need better information about the difficulties experienced by family carers, both prior to the death and afterwards. Of particular interest to policy makers in Northern Ireland was a concern that people from rural areas may be at increasing risk of suicide. We were commissioned by the Health and Social Care R&D Division of the Northern Ireland Public Health Agency to address the gaps in our understanding of suicide in NI. What did we do? We undertook a mixed methods study in which we examined the records of 403 people who took their own lives over a two-year period between March 2007 and February 2009. We linked these data to GP records and then examined help-seeking pathways of people and their contacts with services. We did in-depth face-to-face interviews with 72 bereaved relatives and friends who discussed their understanding of the events and circumstances surrounding the death, the experience of seeking help for the family member, the personal impact of the suicide, and use of support services. Additionally, we interviewed 19 General Practitioners about their experiences of managing people who died by suicide.            

Reframing Scottish Football: Strategy and the short-term nature of the football industry.

Despite football being deeply entrenched in Scottish culture it is under-researched from a business perspective. This research develops a conceptual framework that views professional football clubs from a number of different perspectives. It draws on strategic management literature since this views the firm as the intersection between internal competence, customer perception and competition within an industry. A review of previous sports business research highlighted five main themes that were used to create a structure for the analysis: on-field performance, attendance, finance, the playing squad and the manager. These themes were used as frames to view the firms within the industry from a number of different perspectives. Each frame allows a different aspect of the firm to be considered singly in turn and then collectively to develop a deeper understanding of the existing frames in use within the industry. The research is based on a pragmatic philosophy that allows mixed methods to be combined to provide both an objective and subjective view of the industry. The subjective view was drawn from five interviews with senior figures within Scottish professional football. These participants were from a number of different roles and organisations within the industry to provide a balance of experiences. The views were triangulated with a descriptive analysis of secondary data from a number of industry sources to establish patterns within and between these frames. A peer group of six clubs was selected as they competed in the Scottish Premier League in each of the seasons within an eleven-year period (2000-2011). The peer group clubs selected were: Aberdeen, Dundee United, Heart of Midlothian (Hearts), Hibernian, Kilmarnock and Motherwell. By focussing on a small group of clubs with a similar on-field record a broad study across the five frames could be carried out in detail without the findings being influenced by the impact of relegation to a lower division or sustained participation in European football. Within each of the original five frames a number of sub-components were identified and linked to the framework; this expanded the content to reflect the findings of this project. There appeared to be little link between on-field performance and attendance although progress to the later stages of cup competitions allowed clubs to connect with fans who do not regularly attend. The relationship between a club’s income and wage bill should be expanded to include interest repayments since this expenditure can be used to highlight future financial problems caused by increased debt levels. Although all of the interview participants spoke with pride of the players that had progressed from the club’s youth academy to success at the highest level the peer group clubs only produced one player each season that played more than ten matches for the club. Almost half of the players signed from the youth academy left the club without playing for the 1st Team. The importance of the relationship between the manager and club chairman was highlighted, although the speed with which managers were appointed suggests that little consideration was given to this before offering a contract. Once appointed there appeared to be little clarity over the job description and areas of responsibility. Several of the interviewees brought experience from other businesses to football but admitted that short-term decision making and entrenched behaviour made change difficult. The conclusion of the research is that by taking a firm-wide view of the club, longer-term decisions can be taken within football. Player development and supporter relationships were both identified as long-term processes that are impacted by the current short-termism. With greater role clarity for managers and a mixture of short and long-term objectives those involved in the industry are more likely to have opportunities to learn from experience and performance, across the different frames, will improve as a result.
