Shipping the art is not included in the sale price. The item/items will be shipped directly from the artist. This is to mitigate damage to the art in transit. The majority of our artists are UK based, however, many are from South Afracica, Europe and the USA.
Once the art is purchased, the artist will contact you to arrange shipping and to make arrangements for the shipping payment. They are also happy to chat and answer any questions you might have.
Please take note that there may be import/export costs payable for international deliveries.
If you wish to discuss anything before purchasing art, please contact us via the live watsapp chat button or email [email protected].
Lesley has lived in the Aberdeen area all her life. Originally a graphic designer, she worked in the oil industry until deciding to ‘go it alone’ in 1996. Since then Lesley has developed an enthusiastic fan base who love her lifelike sculptures and striking animal portraits. As a youngster, Lesley would often find and study unfortunate road casualties and compare them with human anatomy drawings, this way she learned how the bone and muscle structures worked and was able to sketch many animals from her new found knowledge and memory. She still employs this method today explaining “It’s a spontaneous way of working that suits my personality.”
Lesley’s preferred medium is oil on canvas though she also works with acrylic and watercolour as well as creating lifelike ceramic animal sculptures.
Lesley is involved with several wildlife organisations and as a trustee for Blankets for Baby Rhinos she actively contributes and fundraises personally and through the sale and donations of her artworks. Her work is available in several of Scotland’s leading galleries and is collected internationally. This year Lesley was a finalist in the DSWF Wildlife Artist of the Year Awards 2022 with her walrus sculpture “Sunkissed”, this piece has now since sold.
Loss of Arctic sea ice due to climate change is the most serious threat to Polar Bears throughout their circumpolar range (Obbard et al. 2010, Stirling and Derocher 2012, USFWS 2015). We performed a data-based sensitivity analysis with respect to this threat by evaluating the potential response of the global Polar Bear population to projected sea-ice conditions. Our analyses included a comprehensive assessment of generation length (GL) for Polar Bears; development of a standardized sea-ice metric representing important habitat characteristics for the species; and population projections, over three Polar Bear generations, using computer simulation and statistical models representing alternative relationships between sea ice and Polar Bear abundance.
Our analyses highlight the potential for large reductions in the global Polar Bear population if sea-ice loss continues, which is forecast by climate models and other studies (IPCC 2013). Our analyses also highlight the large amount of uncertainty in statistical projections of Polar Bear abundance and the sensitivity of projections to plausible alternative assumptions. Across six scenarios that projected polar bear abundance three generations forward in time using the median and 95th percentile of estimated GL, the median probability of a reduction in the mean global population size greater than 30% was approximately 0.71 (range 0.20-0.95; see Table 4 in the attached Supporting Material). The median probability of a reduction greater than 50% was approximately 0.07 (range 0-0.35), and the probability of a reduction greater than 80% was negligible. The International Union for the Conservation of Nature Red List Guidelines suggests that assessors consider nearly the full range of uncertainty in potential outcomes, and adopt a precautionary but realistic attitude toward risk tolerance (Section 3.2.3, IUCN 2014). In light of the significant probability, across scenarios, of a reduction in mean global population size greater than 30%, and the relatively low probability of a reduction greater than 50%, we conclude that Polar Bears currently warrant listing as Vulnerable under criterion A3c (IUCN 2014).
