Topic: Altitude reached by Vipera berus in UK?
Hi I do appreciate that the locations were very remote, but I'm particularly worried about berus being persecuted and as the rule was agreed by all the original forum members I felt it best they were deleted.

Oops, sorry, spot the new guy. In precis they were records from 390/395m elevation in northern Scotland. I've also seen adders at about 370m in the galloway forest park in SW Scotland. Ewan. Ewan Shilland Contract Research Scientist Environmental Change Research Centre University College London |

Topic: DEFRA Review of Non-native Species Policy
The following recent DEFRA review may be of interest to those of you who deal with non-native invasives and/or may be called upon to provide herp advice for any future legislation. http://www.defra.gov.uk/wildlife-countryside/resprog/findings/non-native/index.htm Here's a flavour of the document, taken from the executive summary: It is thereforeconsidered that the UK should: ò Establish a Non-native Species Council to oversee policy co-ordination and dissemination of advice and guidance. This Council should be invested with the power to direct actions of organisations involved with non-natives, to assign clear responsibilities to appropriate bodies, to consider the crosscutting aspects of non-native species issues, and to provide technical and scientific advice to Government. ò Draw up a Non-Native Species Strategy for Great Britain. This strategy should include the collation of existing legislation and guidance; identification of sectors and pathways associated with introductions / use of non-natives; a review of the status and threats of established non-native species; lists of species which have been identified as potentially invasive but not yet established, and for which early warning of introduction is a priority; and procedures for early detection of, monitoring and collation of information on non-native species. ò Ban the keeping and sale of known invasive species.

Topic: Potential CCW Herp Conservation Funding.
From http://www.ccw.gov.uk/news/index.cfm?action=Press&ID=529&lang=en Note the December 1st deadline. Ewan 27/10/2003 Are you up for a species challenge? PRACTICAL PROJECTS to conserve rare species will get a ú600,000 boost from the Countryside Council for Wales over the next three years. Grants are being offered to voluntary bodies and individuals who want to join the campaign to save WalesÆ rare or declining wildlife species. There are 175 species in need of conservation care in Wales. The scheme will run from 1 April 2004, but applications need to reach CCW by 1 December 2003. Applicants can submit project proposals covering one, two or three years. There will be a second application round in the Autum of 2004, and a third in the Autumn of 2005. The projects can range from wildlife surveys and monitoring to practical habitat restoration work. The brown, hare, red squirrel, grey partridge, great crested newt, medicinal leech, wild asparagus, and fen orchid are just some of the better known species on the list. Dr Malcolm Smith, CCW senior director said: ôUsing our Species Challenge Fund, we want to help voluntary groups and individuals play a bigger part in boosting the populations of important species. Not all of them are rare, but they are all suffering declines. ôVoluntary groups and individuals are often best placed to manage wildlife projects at a practical and local level. The richness of our natural environment is not something we can take for granted. It needs help. And it is crucial to the economic and social wellbeing of all the people of Wales." The normal level of support from CCW is 50 per cent. The list of priority species, as well as the species challenge grant forms, is available from Rhian Jones, CCW Grants Unit on (01248) 385500. Ends More information: Meinir Wigley, Senior Public Relations Officer, on 07720 428644 NOTE TO EDITORS - CCW is the GovernmentÆs statutory adviser on sustaining natural beauty, wildlife and the opportunity for outdoor enjoyment throughout Wales and its inshore waters.

Topic: reptiles of Qatar
If you fancy something a little more swashbuckling to read on your flight across you could try: A Camel Journey across the Rub' Al Khali Bertram Thomas; B. K. N. Wyllie The Geographical Journal, Vol. 78, No. 3. (Sep., 1931), pp. 209-238. which was the only article to come up in a JSTOR search for "Qatar and reptile". http://uk.jstor.org/ The authors start their trek somewhere on the coast near the border between present day Oman and Yemen and end up in Doha, Qatar. It would appear they collected all sorts of specimens en route, including a variety of reptiles listed on pages 228 to 230. Good luck Ewan.

Topic: Herp Workers for Operation Wallacea
This arrived in the one of the listservs I'm on and may be of interest to some in the RAUK forum. I personally have no connection with, nor prior knowledge of, the organisation but the web site checks out. Ewan From: Linda A Weir To: PARC@LISTSERV.UGA.EDU Sent: Tuesday, February 03, 2004 8:07 AM Subject: Operation Wallacea - Honduras, Indonesia I was asked to post the following announcement to the PARC listserve. Please contact Dr. Tim Coles if you are interested in assisting. Operation Wallacea is looking for herpetologists to help with surveys this coming summer in Honduras or in Indonesia. Operation Wallacea (see www.opwall.com) is an organisation funded by paying volunteers, which establishes extensive monitoring programmes in remote areas for assessing changes in factors such as socio- economics, forest structure, biodiversity (using indicator groups such as herpetofauna) and population levels of key species. In Indonesia the programme has been running for 8 years and has now attracted substantial funding from GEF. In Honduras we are in the process of establishing a similar programme and the results from the surveys in 2004 are being used as a baseline against which future changes can be assessed. In Honduras we are operating four camps within the Merendon Mountains along the northern border with Guatemala. One camp is in a lowland forest valley, one at 1200m in the buffer zone of the Cusuco National Park and two at 1700m in the core zone of the National Park. We are looking for a herpetologist to man each of the camps for a 10 week period starting 26 June. We are intending to have an extensive network of pitlines established at each of the sites covering areas of undisturbed forest through to highly disturbed and open areas. In addition there will be a network of cover boards at each of the sites and the herpetologists will need to complete opportunistic transect searches each day. These posts are not funded but on site costs will be covered. This is however, an excellent opportunity for graduates or postgraduates with an interest in herpetology and previous experience of handling poisonous snakes to gain experience of Central America fieldwork. There is one further herpetology post that we are looking to fill in Honduras. This is to complete a population study of the pink subspecies of Boa Constrictor which lives only on the two islands of the Cayos Cochinos. This sub species is protected under Honduran legislation but there appears to be a flourishing illicit trade in the sale of these animals to collectors. The objective of this project which runs from the same dates would be to obtain an estimate of the population size on both islands. The snakes are fairly easy to capture and these would then be pit tagged and released. Given the relatively small size of the islands it is possible to search a fairly large part of them for the snakes, which should give fairly precise population estimates. In addition this study would also complete an assessment of the other herpetofauna species on the island from pit lines and opportunistic searching. In addition to these posts though we are looking for a herpetologist with a strong publication record to help set up the surveys in the field and then to utilise the information collected for one or more publications. In this case the costs of flights as well as the on site costs will be covered. If the herpetofauna project runs well this season then we might be interested in running the project in 2005 by funding a PhD student as we have done for many of the Indonesian marine projects. In Indonesia we are designing the survey work as a precursor to a full GEF monitoring programme. I have attached the GEF project description and the appendix which describes how the monitoring programme is used to assess performance against various socio-economic, forest structure, biodiversity and population levels of key species criteria. We will be working at 9 sampling nodes (3 in undisturbed forest, 3 in moderately disturbed forest and 3 in disturbed forest). The nodes will be spread right across the Lambusango Forest Management Area in central Buton Island. The science teams will visit each of the nodes for a week on a rolling programme starting 17 July. The herpetofauna work which will be co- ordinated through the Arthur Rylah Institute in Melbourne will involve a postdoc (for preference) or a postgrad with Asia Pacific herpetology experience running pit traps and cover boards at each of the sampling nodes and completing opportunistic search transects. This project will cover the field costs and a ?ú500 travel grant. The successful applicant will need to be on site for a 10 or 12 week period starting on 25 June 2004 in Makassar. I hope these projects are of interest to some of your contacts.

Topic: Acid water = stunted tadpoles?
Hi Donny A quick literature search would seem to suggest that if your ponds are indeed fairly acid then that would go some way towards explaining any impaired tadpole development. Ewan. 1. Author(s): Glos J; Grafe TU; Rodel MO; Linsenmair KE Title: Geographic variation in pH tolerance of two populations of the European common frog, Rana temporaria Source: COPEIA 2003, Iss 3, pp 650-656 Abstract: In a laboratory experiment, we investigated the effects of low pH environment, a key parameter of acidity, on mortality, growth, and development in two populations of Rana temporaria that differ in the pH of their breeding ponds. In a population with pH neutral breeding sites, low pH treatment caused a prolongation in embryogenesis and an increased embryonic mortality, a higher proportion of deformed hatchlings and an increased larval time. Embryos and larvae from a population that was exposed naturally to low pond pH were more pH tolerant, as the only effect of low pH was increased larval time. 2. Author(s): Pakkasmaa S; Merila J; O'Hara RB Title: Genetic and maternal effect influences on viability of common frog tadpoles under different environmental conditions Source: HEREDITY 2003, Vol 91, Iss 2, pp 117-124 Abstract: The influence of environmental stress on the expression of genetic and maternal effects on the viability traits has seldom been assessed in wild vertebrates. We have estimated genetic and maternal effects on the viability (viz probability of survival, probability of being deformed, and body size and shape) of common frog, Rana temporaria, tadpoles under stressful (low pH) and nonstressful (neutral pH) environmental conditions. A Bayesian analysis using generalized linear mixed models was applied to data from a factorial laboratory experiment. The expression of additive genetic variance was independent of pH treatments, and all traits were significantly heritable (survival: h(2) approximate to 0.08; deformities: h(2) approximate to 0.26; body size: h(2) approximate to 0.12; body shape: h(2) approximate to 0.14). Likewise, nonadditive genetic contributions to variation in all traits were significant, independent of pH treatments and typically of magnitude similar to the additive genetic effects. Maternal effects were large for all traits, especially for viability itself, and their expression was partly dependent on the environment. In the case of body size, the maternal effects were mediated largely through egg size. In general, the results give little evidence for the conjecture that environmental stress created by low pH would impact strongly on the genetic architecture of fitness-related traits in frogs, and hamper adaptation to stress caused by acidification. The low heritabilities and high dominance contributions conform to the pattern typical for traits subject to relatively strong directional selection. 3. Author(s): Pahkala M; Rasanen K; Laurila A; Johanson U; Bjorn LO; Merila J Title: Lethal and sublethal effects of UV-B/pH synergism on common frog embryos Source: CONSERVATION BIOLOGY 2002, Vol 16, Iss 4, pp 1063-1073 Abstract: Although the negative effects of ultraviolet-B (UV-B) radiation on the development of many amphibian species have been demonstrated, some species-such as the common frog (Rana temporaria)-seem to be tolerant of UV-B radiation. The amount of UV-B radiation received is likely to vary among populations of the same species, but little is known about geographic variation in UV-B tolerance. Similarly, although UV-B radiation can have synergistic effects with other stressors, no studies have focused on geographic variation of these effects on amphibians. We investigated the synergistic effects of UV-B radiation and low pH on hatchability and early development of R. temporaria embryos in a factorial laboratory experiment with animals originating from southern and northern Sweden. Newly fertilized eggs were exposed to three different UV-B treatments (no UV-B [control], 1.254 k/J/m(2) [normal] and 1.584 k/J/m(2) [26% enhanced]) and two pH treatments (4.5 [low] and 7.6 [neutral]). Ultraviolet-B radiation in combination with low pH lead to markedly (approximately 50%) reduced survival rates and increased (approximately 30%) frequency of developmental anomalies in the northern but not in the southern population. The UV-B- exposed embryos hatched at smaller size in the southern population, whereas low pH reduced hatchling size in both populations. In both populations and pH treatments, embryos in the normal UV-B treatment developed significantly faster than embryos in the enhanced or control UV-B treatments. No interaction between pH and UV-B on developmental rates or hatchling size was detected. The results demonstrate-contrary to earlier belief-that R. temporaria embryos are not insensitive to increased levels of UV-B radiation. The lethal effects of UV-B radiation may, however, become manifested only in combination with other stressors, such as low pH, and the effects of this synergism may differ among different populations of the same species. 4. Author(s): Surova GS Title: Effects of acid environmental conditions on viability of the common frog (Rana temporaria) eggs Source: ZOOLOGICHESKY ZHURNAL 2002, Vol 81, Iss 5, pp 608-616 Abstract: The influence of high water acidity on the viability of large and small eggs of Rana temporaria L. were studied in two geographical polulations: in the northern (Solovki Islands) and central (Moscow region) parts of its range. There is intra- and interpopulation variability of egg sizes. In Moscow region, the frog clutches with large (1.8 +/- 0.05 mm diameter) and small (1.5 +/- 0.03 mm. diameter) eggs differ to a greater extent. On the Solovki Islands, eggs are of larger size (2 0.03 mm). The role of acid marsh water (pH 4.5 in Moscow region and 4.9 on Solovki Islands) on the viability of different-sized eggs was estimated experimentally. At the same time, relationhsips between the egg mortality in natural spawning areas and pH of water were studied. The egg mortality was estimated by the percentage of died eggs just before hatching. The initial size of eggs is shown to affect their survival neither in acid nor neutral environmental conditions. The egg mortality in acid water increases to 5%. Inspection of 14 natural ponds (pH from 4.5 to 7.0) has revealed the distinct correlation between the mortality level and water pH value (r = -0.96). A high dispersion of clutches according to the viability of eggs (from 0 to 100%) was found. It was independent of water pH and geographical position of spawning grounds. The large sizes of clutches and egg aggregations protect embryos against acid water, especially in the central pails of the clutches. 5. Author(s): Rasanen K; Laurila A; Merila J Title: Carry-over effects of embryonic acid conditions on development and growth of Rana temporaria tadpoles Source: FRESHWATER BIOLOGY 2002, Vol 47, Iss 1, pp 19-30 Abstract: 1. Conditions experienced during the early stages of development may have carry-over effects on performance during later life. The egg laying period and embryonic development of temperate and boreal zone amphibians often coincides with peak acidity resulting from spring snow-melt, but the effects of acid conditions during embryonic stage on subsequent performance are unknown. 2. We investigated the potential carry-over effects of acidity during the embryonic stage on performance up to metamorphosis in the common frog (Rana temporaria) tadpoles. There were four combinations of acid (4.5) and neutral (7.5) pH treatments applied to the egg and larval stages in a factorial laboratory experiment. In addition, we studied the difference in embryonic and larval tolerance of acidity between two populations originating from circumneutral (pH 6.6) and acidic conditions (pH 4.8). 3. The effects of acid conditions during the embryonic stage were sublethal, as indicated by delayed development and reduced size. Under acid conditions, tadpoles that had been raised in neutral water as embryos at first grew more slowly than tadpoles raised under acid conditions as embryos. At metamorphosis, no effects of embryonic acidity were detectable indicating that tadpoles were able to compensate fully for the initial reduction in growth. 4. Acid conditions during the larval period had a strongly negative effect on survival, size and age at metamorphosis. The amount of food consumed was lower under acid conditions, suggesting that reduced food consumption was at least partly responsible for the negative effects. 5. Although the two populations differed in the length of larval period, there was no indication of a differential response to the treatments in any of the metamorphic traits studied. 6. These results suggest that, although moderate acid conditions during embryonic development affect growth and development negatively, this influence does not persist after conditions have returned to normal. However, even moderately acid conditions during the larval period may have a strong negative influence on survival and performance of the tadpoles.

Topic: Londonos Environment & Future at NHM 1/11
Unfortunately it's a little bit late notice but this only arrived in my inbox today. May be of interest to London & home county herp types. Ewan London's Environment and Future at The Natural History Museum, 1st November 2004. Objectives Following on from two successful LEAF meetings organised by Lord Julian Hunt at University College London in Sept 2002 and by Professor David Goode, Greater London Authority in Nov 2003, the conference seeks to address key recommendations highlighted in LEAF 2 held at GLA. The value of biodiversity to London's economy will be highlighted and particularly the need to properly audit and understand biodiversity in relation to social and economic values. The meeting aims to enhance networking with all stakeholders with an interest in Biodiversity, Environmental Quality and Sustainable Development. Audience Policy makers, private sector, innovators, stakeholders academics, schools, consultants, amateur naturalists and indeed anyone who is working to improve London's environment from a health, living, amenity and leisure perspectives. Deliverables A series of break-out group sessions seek to address the practical policies necessary to achieve the conference goals. Summary points will be circulated to the Mayor of London, Greater London Authority representatives responsible for the various plans, key DEFRA, and other key stakeholders and also placed on www. Biodiversity helps make London one of the most pleasant world cities and a key measure of the state of London's environment and the quality of life of its inhabitants. Londoners are fortunate to be living in one of the greenest cities in the world supporting a remarkable diversity of wildlife adding greatly to peoples enjoyment of London and also help promote tourism essential for London's economy. However, we must not be complacent. The meeting is especially timely in view of recent unusual climatic conditions leading to an impact on environmental quality. I am delighted the Deputy of Mayor of London, Nicky Gavron has kindly agreed to launch the meeting and present the opening speech. Please consult the Natural History Museum Science Web Page to download an application form: http://www.nhm.ac.uk/science/ It is also possible to book by phone: 02079425555, lines are open from 10am-1pm daily.

Topic: GCN egg laying material
Hi I've found this quite often. If you can't see the usual spawn plants, or even any aquatic plants, then scoop your net gently along the surface sediment of the pond and carefully pick through the dead leaves looking for eggs. Generally they will still be folded over. I've found them in the dead leaves of various broadleaved tree sp as well as in mushy dead leaves of various emergent reeds- iris/sparganium/typha etc. Good luck.
