Wright, P.G.R. et al. (2021) Can effective population size estimates be used to monitor population trends of woodland bats? A case study of Myotis bechsteinii.

This paper uses a case study on  the elusive woodland bat Bechstein’s bat (Myotis bechsteinii) to explore the effectiveness of genetic approaches as a way to monitor elusive long-lived species.

In this study, the history of the pine marten (Martes martes) in Ireland is reviewed, revealing that the population has undergone several retractions and expansions over the last few hundred years. Here, we consider the genetic legacy of this flux in fortunes and its likely impacts upon the conservation and future recovery of the species.

Preliminary work towards a sustainable harvesting model of pine martens in Scotland for translocations (to supplement a long-term strategy and recovery plan for pine martens in Britain) Jenny MacPherson, Elizabeth Croose, Ciara Powell, Stephen Carter, Catherine O’Reilly 31 March 2020

Since 2015, VWT has been involved in pine marten translocations from Scotland for population restoration in Wales and, more recently, Gloucestershire. A primary consideration in these translocations has been to minimise the potential for negative impacts on recovering donor populations in Scotland. To this end, surveys and monitoring have been carried out to collect further data to inform the way in which current and future sustainable harvesting models are applied. Based on precautionary principles, VWT adopted a highly conservative approach to trapping and removals in the first instance. Data on indices of marten activity at donor sites to date suggest that this has proved effective, and population estimates derived from genetic analysis of non-invasively collected samples support the suggestion that only a relatively small proportion of resident animals have been removed. However, the sampling strategy could be improved to refine population estimates further and better inform the way in which donor populations are managed and conserved in the face of higher demand from other organisations in future.

Finch, D. et al. (2020) Implications of Endectocide Residues on the Survival of Aphodiine Dung Beetles: A Meta‐Analysis

This quantitative meta-analysis of 22 studies documents the non-target effects of endectocide residues on dung-dwelling organisms,  such as the Aphodiine dung beetle and provides evidence on the consequences of different application methods, and the need for standardised methodological techniques in future studies.

Bavin, D. et al. (2020). Using Q-methodology to understand stakeholder perspectives on a carnivore translocation

As part of a national recovery programme for the pine marten Martes martes, a protected mesocarnivore in the UK, we used Q-methodology to understand the perspectives of residents living in an area in which a pine marten translocation project was planned.

Finch, D. et al. (2020). Traffic noise playback reduces the activity and feeding behaviour of free-living bats

Using a Before-After-Control-Impact phantom road experimental
design, we examine the impacts of traffic noise on bat activity and feeding behaviour.
