The COVID-19 pandemic as a pivot point for biological conservation

The COVID-19 lockdown reduced human mobility and led to immediate insights into how humans impact nature. Yet the strongest ecological impacts are likely to come. As we emerge from the pandemic, governments should avoid prioritizing short-term economic gains that compromise ecosystems and the services they provide humanity. Instead, the pandemic can be a pivot point for societal transformation to value longer term ecosystem and economic sustainability

A Black Deer at Black Cave: New Pictograph Radiocarbon Date for the Lower Pecos, Texas

A Pecos River style painting of a black deer from Black Cave Annex (41VV76a) in southwest Texas was radiocarbon dated. Using plasma oxidation and accelerator mass spectrometry, we obtained an age of 1465 ± 40 RCYBP (2 sigma calibrated age range of A.D. 470-660). This age is younger than the accepted age range for Pecos River style paintings, which is approximately 4000-3000 years B.P. This new measurement in association with other younger dates prompts us to question whether the Pecos River style endured for a longer time period than previously thought. More radiocarbon research is needed in order to understand how this anomalous result might fit within the Lower Pecos Canyonlands rock art chronology

Temporal and spatial variation in temperature experienced by macrofauna at main endeavour Hydrothermal vent field

A significant focus of hydrothermal vent ecological studies has been to understand how species cope with various stressors through physiological tolerance and biochemical resistance. Yet, the environmental conditions experienced by vent species have not been well characterized. This objective requires continuous observations over time intervals that can capture environmental variability at scales that are relevant to animals. We used autonomous temperature logger arrays (four roughly parallel linear arrays of 12 loggers spaced every 10–12 cm) to study spatial and temporal variations in the thermal regime experienced by hydrothermal vent macrofauna at a diffuse flow vent. Hourly temperatures were recorded over eight months from 2010 to 2011 at Grotto vent in the Main Endeavour vent field on the Juan de Fuca Ridge, a focus area of the Ocean Networks Canada cabled observatory. The conspicuous animal assemblages in video footage contained Ridgeia piscesae tubeworms, gastropods (primarily Lepetodrilus fucensis), and polychaetes (polynoid scaleworms and the palm worm Paralvinella palmiformis). Two dimensional spatial gradients in temperature were generally stable over the deployment period. The average temperature recorded by all arrays, and in some individual loggers, revealed distinctive fluctuations in temperature that often corresponded with the tidal cycle. We postulate that this may be related to changes in bottom currents or fluctuations in vent discharge. A marked transient temperature increase lasting over a period of days was observed in April 2011. While the distributions and behavior of Juan de Fuca Ridge vent invertebrates may be partially constrained by environmental temperature and temperature tolerance, except for the one transient high-temperature event, observed fluid temperatures were generally similar to the thermal preferences for some species, and typically well below lethal temperatures for all species. Average temperatures of the four arrays ranged from 4.1 to 11.0 °C during the deployment, indicating that on an hourly timescale the temperature conditions in this tubeworm community were fairly moderate and stable. The generality of these findings and behavioural responses of vent organisms to predictable rhythmicity and non-periodic temperature shifts are areas for further investigation

Temperature-driven biodiversity change : disentangling space and time

HR09011), the European Research Council grant nos. ­AdG-250189 (BioTIME) and PoC-727440 (BioCHANGE).Temperature regimes have multiple spatial and temporal dimensions that have different impacts on biodiversity. Signatures of warming across these dimensions may contribute uniquely to the large-scale species redistributions and abundance changes that underpin community dynamics. A comprehensive review of the literature reveals that 86% of studies were focused on community responses to temperature aggregated over spatial or temporal dimensions (e.g., mean, median, or extremes). Therefore, the effects of temperature variation in space and time on biodiversity remain generally unquantified. In the present article, we argue that this focus on aggregated temperature measures may limit advancing our understanding of how communities are being altered by climate change. In light of this, we map the cause-and-effect pathways between the different dimensions of temperature change and communities in space and time. A broadened focus, shifted toward a multidimensional perspective of temperature, will allow better interpretation and prediction of biodiversity change and more robust management and conservation strategies.Publisher PDFPeer reviewe

Are Killer Bees Good for Coffee? The Contribution of a Paper\u27s Title and Other Factors to Its Future Citations

How can the title of a paper affect its subsequent number of citations? We compared the citation rate of 5941 papers published in the journal Biological Conservation from 1968 to 2012 in relation to: paper length; title length; number of authors; paper age; presence of punctuation (colons, commas or question marks); geographic and taxonomic breadth; the word ‘method’; and the type of manuscript (article, review). The total number of citations increased in more recently published papers and thus we corrected citation rate (average number of citations per year since publication) by publication age. As expected, review papers had, on average, twice the number of citations compared to other types of articles. Papers with the greatest geographic or taxonomic breadth were cited up to twice as frequently as narrowly focused papers. Titles phrased as questions, shorter titles, and papers with more authors had slightly higher numbers of citations. However, overall, we found that the included parameters explained only 12% of the variability in citation rate. This suggests that finding a good title is necessary, but that other factors are more important to construct a well-cited paper. We suggest that to become highly cited, a primary requirement is that papers need to advance the science significantly and be useful to readers

Manx shearwater (Puffinus puffinus) rafting behaviour revealed by GPS tracking and behavioural observations

Before visiting or leaving their remote island colonies, seabirds often engage in a behaviour termed ‘rafting’, where birds sit, often in groups, on the water close to the colony. Despite rafting being a widespread behaviour across many seabird taxa, the functional significance of rafting remains unknown. Here we combine global positioning system (GPS) tracks, observational and wind condition data to investigate correlates of rafting behaviour in Manx shearwaters (Puffinus puffinus) at a large colony on Skomer Island, Wales. We test (1) the influence of wind direction on rafting location and (2) whether raft size changes with respect to wind speed. Our approach further allows us to describe day-night trends in (3) raft distance from shore through time; (4) the number of birds present in the nearshore waters through time; and (5) spatial patterns of Manx shearwater rafts in marine waters adjacent to the breeding colony. We find no evidence that wind direction, for our study period, influences Manx shearwater rafting location, yet raft size marginally increases on windier days. We further find rafting birds closer to the shore at night than during the day. Thus, before sunset, birds form a “halo” around Skomer Island, but this halo disappears during the night as more individuals return from foraging trips and raft nearer the colony on Skomer Island. The halo pattern reforms before sunrise as rafts move away from land and birds leave for foraging. Our results suggest that wind conditions may not be as ecologically significant for rafting locations as previously suspected, but rafting behaviour may be especially important for avoiding predators and cleaning feathers

Development of a training programme for primary care mental health staff to support management of depression and anxiety in long-term conditions

Aim: We aimed to develop, deliver and evaluate a brief training programme for primary care mental health staff in NW London focussing on long-term physical health conditions (LTCs). The objective was to improve participants’ knowledge, understanding and confidence (self-efficacy) in providing effective support to people with LTCs. The second objective was to develop an online version to be made available more widely. Background: The project was commissioned by NW London Collaboration of Clinical Commissioning Groups as part of a strategy to develop more joined up care and support for people with mental health needs. Training was developed by a team of experts, with input from commissioners, service users, clinicians and service managers. Methods: Training was delivered via two-day interactive workshops providing: (i) key facts (informed by a review of published research and publically available health information); (ii) opportunity to engage with the ‘lived experience’ of people with LTCs (via videos, role plays, case studies and group discussion); (iii) skills-based training (in specific assessment and intervention methods). Knowledge, understanding and confidence (with respect to supporting people with LTCs) were assessed at the start and end of the training. An online training programme (with embedded evaluation questionnaire) was also developed, covering the same themes as the workshop. Findings: Mental health staff (n=60) reported limited knowledge, understanding and confidence before the workshop, underlining the need for training. Knowledge of LTCs improved significantly following training (P<0.0001), along with awareness of the impact of poor psychological wellbeing on physical health (P<0.05) and the role of psychological therapies in supporting people with LTCs (P<0.0001). Self-efficacy also improved (P<0.001). Online training was accessed by 894 participants in the first six months and 187 provided feedback via the evaluation questionnaire. Responses indicated that participants found the training useful (88%), interesting (91%) and easy to understand (97%)
