Posted: 14 Jul 2003 Topic: Altitude reached by Vipera berus in UK?



Hi
I've seen V. berus at the following two locations and elevations that may be of use to you:

Hi Ewan, welcome to RAUK, we have a policy of not giving precise locations openly on the forum, so I have removed your references. Please only communicate precise locations privately by the forum PM system or e-mail in future.

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.


Cheers

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.

Posted: 17 Jul 2003 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.

Dear Tony

Here At UCL Geography department we have a cartography unit who produce excellent maps and diagrams for publications and books.
They do work both within the dept and for external clients. I believe their external work is charged at 25 pounds an hour - a very reasonable rate and approximately half the price of other bureaus in the area.
If you wish to get on touch with them please email either Cath cpyke@geog.ucl.ac.uk or Elanor emcbay@geog.ucl.ac.uk
They are on the web at:

Posted: 28 Oct 2003 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.

Posted: 11 Feb 2004 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

Posted: 02 Mar 2004 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.

Posted: 13 May 2004 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.

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.

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.

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.

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. Please note we cannot accept bookings after 21st October.

Doctoral Student in need of canopy herpetofauna research assistants
Location: Ecuadorian Amazon


Job Description:
Motivated, reliable, and durable field assistant to work on a field study of
the herpetofauna and arthropod communities of canopy phytotelmata
(tank-bromeliads) in primary rainforest at the Tiputini Biodiversity Station
(TBS), Yasuni Research Station (YRS), and along the Via Auca in the
Ecuadorian Amazon. Assistants will contribute to a project focusing on
amphibian and arthropod diversity and density in a large canopy
tank-bromeliad, Aechmea zebrina, occupying different forest types and
management regimes Assistants will be responsible for independent scouting
surveys to identify potential survey trees, providing ground support during
sampling, collecting/recording data during sampling, transporting heavy gear
and sampled bromeliads long distances in difficult terrain, following
protocol to collect data for each bromeliad, dismantling bromeliads in a
screen tent and collecting all herpetofauna and arthropods, recording
specimen data, collecting blood or tissue samples, preserving specimens,
sorting arthropods, and data entry. Other responsibilities may include tree
and trail mapping, Visual Encounter Surveys (VES), and opportunistic sampling.

Cost/funding:
A portion of costs will be paid by the project, applicants will pay
approximately US$ 13-15/day towards station fees (includes on-site lodging,
laundry, and three meals daily). Successful Ecuadorian applicants may apply
to have station fees paid in full. Assistants are also responsible for the
costs of obtaining a visa to work in Ecuador if staying longer than 90 days
(~US$ 300), health insurance and immunizations that permit that work. Proof
of suitable insurance and yellow fever immunization is a must; vaccinations
against typhoid, rabies, hepatitis, etc. are all also strongly recommended
(see the Center for Disease Control website for Ecuador,
http://wwwn.cdc.gov/travel/destinationEcuador.aspx). Applicants must also
pay their own round-trip airfare to Ecuador (cost varies) and for travel
within Ecuador to and from the research station (~US$120 by plane or US$20
by bus). Assistants are responsible for their own field clothes, gear, and
personal items.

Term of Appointment:
Minimum 3 month commitment; exceptional applicants may inquire about a
shorter commitment (not less than 2 months). Research will commence at the
beginning of March 2008 and finish at the end of December 2008. Preferred
commitment dates would be: 1. March, April, and May-June; 2.May- June, July,
and August-September; 3. September-October, November, and December. I would
like to have assistants overlap at least a week.

Qualifications:
Applicants should minimally have significant progress towards a BS/BA (or
higher degree) in Biology, Ecology, or a related field. Previous experience
with amphibians, reptiles, or arthropods is not necessary but a strong
interest in these animals and the mental tenacity to handle them is
required. Previous experience and comfort with living and working outdoors
is strongly preferred. The ideal applicant should have prior experience with
living or working in a foreign country, preferably a developing country in
the tropics. Knowledge of English is required and Spanish is helpful, but
not necessary, a willingness to learn will benefit greatly. Experience with
collecting systematic data in a scientific context is preferred, the
commitment to learn is a must. Tree climbing experience using Single-Rope
Technique (SRT) is highly preferred; those interested in learning this skill
if accepted should look online for training opportunities. In general,
applicants must be in good physical and mental condition; feel comfortable
being far away from family and friends; be emotionally mature, energetic,
respectful of others, and very patient; have an excellent eye for detail;
experience with bugs, snakes, frogs, heights, and being alone in the forest
(day or night); have very good social skills, especially in small groups;
and be able to maintain a positive and humorous attitude towards challenging
and tiring work.

Posted: 21 Jan 2011 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.
