Ensuring that conservation decisions are informed by the best available data is a fundamental challenge in the face of rapid global environmental change. Too often, new science is not easily or quickly translated into conservation action. Traditional approaches to data collection and science delivery may be both inefficient and insufficient, as conservation practitioners need access to salient, credible, and legitimate data to take action. Open access data could serve as a tool to help bridge the gap between science and action, by providing conservation practitioners with access to relevant data in near real time. Broadscale citizen-science data represent a fast-growing resource for open access databases, providing relevant and appropriately scaled data on organisms, much in the way autonomous sensors do so on the environment. Several such datasets are now broadly available, yet documentation of their application to conservation is rare. Here we use eBird, a project where individuals around the world submit data on bird distribution and abundance, as an example of how citizen-science data can be used to achieve tangible conservation science and action at local, regional, and global scales. Our examination illustrates how these data can be strategically applied to improve our understanding of spatial and temporal distributions of birds, the impacts of anthropogenic change on ecological systems, and creative conservation solutions to complex problems. We raise awareness of the types of conservation action now happening with citizen-science data, and discuss the benefits, limitations, and caveats of this approach.

International audienceFor the first time, subelectron readout noise has been achieved with a camera dedicated to astronomical wavefront-sensing applications. The OCam system demonstrated this performance at a 1300 Hz frame rate and with 240 x 240 pixel frame size. ESO and JRA2 OPTICON jointly funded e2v Technologies to develop a custom CCD for adaptive optics (AO) wavefront-sensing applications. The device, called CCD220, is a compact Peltier-cooled 240 x 240 pixel frame-transfer eight-output back-illuminated sensor using the EMCCD technology. This article demonstrates, for the first time, subelectron readout noise at frame rates from 25 Hz to 1300 Hz and dark current lower than 0.01 e(-) pixel(-1) frame(-1). It reports on the quantitative performance characterization of OCam and the CCD220, including readout noise, dark current, multiplication gain, quantum efficiency, and charge transfer efficiency. OCam includes a low-noise preamplifier stage, a digital board to generate the clocks, and a microcontroller. The data acquisition system includes a user-friendly timer file editor to generate any type of clocking scheme. A second version of OCam, called OCam(2), has been designed to offer enhanced performance, a completely sealed camera package, and an additional Peltier stage to facilitate operation on a telescope or environmentally challenging applications. New features of OCam(2) are presented in this article. This instrumental development will strongly impact the performance of the most advanced AO systems to come

Accessible summary This paper considers what we know about the life stories of people with learning disabilities. It was inspired by one of the authors sharing his own life story. It explores what a life story is. It discusses how life stories help us to understand more about people's lives and history It reviews what we know about how people with learning disabilities can record their stories, including people with high support needs We know life stories can help people to get good support and person‐centred care But we found that people's stories are often lost when there are big changes in their lives We found that staff may not have the skills or confidence to support people to tell and record their stories We think it is important to find out how life stories can be used to support better care for more people. ​ Abstract In this paper, the authors review life stories in learning disability research and practice since the 1960s. Although there is consistent evidence of their value in giving people a voice and an identity beyond the service label, they are not widely used in the provision of health and social care. This is despite long‐standing policy commitments to person‐centred practice. The paper explores possible barriers to the use of life story work and what further research is needed if they are to be more widely and effectively used in practice.
