The Power of Plankton

This animation is aimed at all age groups of the general public. The animation promotes the importance of plankton and the long term Continuous Plankton Recorder (CPR) survey.

The power of shell rapping influences rates of eviction in hermit crabs

Hermit crabs fight for ownership of shells, and shell exchange may occur after a period of shell rapping, involving the initiating or attacking crab bringing its shell rapidly and repeatedly into contact with the shell of the noninitiator or defender, in a series of bouts. The temporal pattern of rapping contains information about the motivation and/or relative resource holding potential (RHP) of the initiator and acts as a repeated signal of stamina. Here we investigated the role of the force with which the rapping is performed and how this is related to the temporal pattern of rapping by rubberizing the external surface of shells. Initiators that are prevented from rapping with their usual level of force persist with the activity for longer over the whole encounter but use fewer raps per bout and are less likely to effect an exchange than those supplied with control shells. The fact that the force of rapping affects the likelihood of a crab being victorious suggests that either the force of rapping contains information about motivation or RHP or that force directly affects noninitiators, reducing their ability to maintain an adequate grip on their shells. The data suggest that shell rapping is an agonistic signal rather than one that provides information useful to the noninitiator, as has been suggested by the negotiation model of shell exchange.

Harnessing the power of personality assessment:Subjective assessment predicts behaviour in horses

Objective assessment of animal personality is typically time consuming, requiring the repeated measure of behavioural responses. By contrast, subjective assessment of personality allows information to be collected quickly by experienced caregivers. However, subjective assessment must predict behaviour to be valid. Comparisons of subjective assessments and behaviour have been made but often with methodological weaknesses and thus, limited success. Here we test the validity of a subjective assessment against a battery of behaviour tests in 146 horses (Equus caballus). Our first aim was to determine if subjective personality assessment could predict behaviour during behaviour testing. We made specific a priori predictions for how subjectively measured personality should relate to behaviour testing. We found that Extroversion predicted time to complete a handling test and refusal behaviour during this test. It also predicted minimum distance to a novel object. Neuroticism predicted how reactive an individual was to a sudden visual stimulus but not how quickly it recovered from this. Agreeableness did not predict any behaviour during testing. There were several unpredicted correlations between subjective measures and behaviour tests which we explore further. Our second aim was to combine data from the subjective assessment and behaviour tests to gain a more comprehensive understanding of personality. We found that the combination of methods provides new insights into horse behaviour. Furthermore, our data are consistent with the idea of horses showing different coping styles, a novel finding for this species. © 2013 Elsevier B.V.

Understanding the Patient Experience Through the Power of Film: a Mixed Method Qualitative Research Project

Film is a highly attractive teaching instrument for the study of different terminal diseases, exploring bioethics (Beauchamp and Childress, 2009) and is a preferred medium over traditional lectures (Edmunds, 2013) to provide realistic examples for adult learners. It can tap into ethical issues; facilitate decision-making; and examine underlying issues such as euthanasia; assisted suicide; and professional responsibility. Contrast this with standard means of teaching, such as scenarios- although a useful pedagogic tool, these are limited because students must imagine the clinical scenario. Film can fill that imaginative gap (Volandes, 2007). It can be utilised as an active teaching strategy for a variety of topics in nursing (Edmunds, 2013) providing a unique way to promote active learning in nursing education (Herrman, 2006). The objectives of the study, aim to help pre registration student nurses from each year of study to engage with their role as health care professionals; provide open discussion and debate on how they view the personal experience of illness/disease/disability/death and to reflect on their role and provision of patient care. It is delivered in 3 tiers to provide a range of data for thematic analysis; 1) Film screening followed by a ‘5 minute reaction’ discussion and post screening questionnaire; 2) Pre screening guided activities for reflection and discussion; 3) Focus groups. This project meets identified aims from the UK Professional Standards Framework (UKPSF) by fostering creative and innovative approaches to teaching and learning; facilitating and supporting the design and delivery of continuing education development programmes and activities; and demonstrates professionalism that staff and institutions bring to teaching. Preliminary feedback and themes will be presented.
