Introduction Annually,about865,000specimensoflivetortoisesandfreshwaterturtles(Testudines)listedintheAppendicesoftheConventiononInternationalTradeinEndangeredSpeciesofWildFaunaandFlora(CITES)are legally traded.Thevastmajorityof thoseoriginate fromcaptive-breedingand ranchingfacilities (CITES, CoP17 Doc. 73). CITES requires documentation of the source of a specimen andappliesstrictconditionsthathavetobemetwhenaspecimenisdeclaredasproducedincaptivity.The high number of transactions of specimens claimed to be produced in captivity, however, hasraisedconcernsaboutthepotentialmisuseofsourcecodes.Claimsofcommercialcaptive-breeding(sourcecodeC) isespeciallyquestionableformanyturtlesandtortoisesas itrequiresconsiderableamounts of money and expertise and many turtles and tortoises grow slowly and mature late,making commercial captive-breeding unprofitable (Nijman & Shepherd, 2009; TRAFFIC, 2013).Customofficersandinspectionofficialsarechallengedtoidentifymisuseofsourcecodes,giventhehighnumbersofexportsand imports.Theaimof thismanual is therefore toprovideguidance forinspectionofficialsandcustomsofficersandCITESManagementandScientificAuthorities toaid intheidentificationofpotentialmisuseofsourcecodes.

Some traits that are important to consider include: Age at firstreproduction,clutchsize,numberofclutchesperyear,inter-birth-intervals,survivalratesofeggsandjuvenilesandthespeciesreproductivelifespan.To aid in the assessment of biological breeding limitswe developed a database of demographic life historytraits that can help to inform the CITES Management and Scientific Authorities (APPENDIX B).

APPENDIX A Supplemental information on advanced methods for the differentiation of captive vs. wild origin
1. Parasites 2. Stable isotope analysis 3. Blood parameters 4. Genetic samples 5. Individual Marking and Passport
1. Parasites:Parasitescanserveasareliableindicatorofwildoriginoftradedspecimensbecausemanyparasiteshave highly complex life-cycles and restricted geographic ranges. Of particular importance arespeciesthatrequireoneorseveral intermediatehostspeciestocompletetheir lifecycle (socalledheteroxenous species). These are very unlikely to occur in captivity, because the respective hostspeciesareusuallynotpresent in captiveenvironments.Notallparasiteswillbe indicativeofwildorigin, the correct sampling and the determination of the type of parasite is therefore of crucialimportance.Groupsofparasiteswithhighforensicvalueincheloniansincludetheprotozoanbloodparasites Haemogregarines and Haemosporidia, which can be detected in blood smears; internalparasites such as Trematodes (flukes), Cestodes (tapeworms), Acanthocephalans (thorny-headedworms)andNematodes,particularSpirurida&Filaria(roundworms).Theirstages(ususallyeggs)canbedetectedinfecalsamples,andsometimesinorgansorundertheskin,larvaeoffilaria,socalledmicrofilariae,aredetectedinbloodsmears.Externalparasitesincludeticksandleeches.Bloodparasites:Haemogregarines (Protozoa) stages detectable in blood and tissue of turtles and tortoises oftentransmittedviablood-suckinginvertebrates(leeches,ticks,mosquitoesetc.)(Kreier,1977),normallynotpresent in captivity. Infections canbedetected inblood smears and infectionpersists inwild-caught individualsevenafteryearsof rearing incaptivity (Širokýetal.,2004).Haemoliviaspp.andHepatozoonspp.areespeciallyimportantindeterminingthegeographicoriginoflandtortoises(e.g.HaemoliviamauritanicadoesnotoccurinCentralEurope;Hepatozoonfitzsimonsi isonlypresentinAfrican terrestrial tortoises such as in some species of the genusKinixys (Cook et al., 2014)). Thegenus Haemogregarina (Placobdella in Europe) can be an important indicator found mostly inaquaticturtles(DvořÁkovÁetal.,2015).Forexample,Haemogregarinasp.wasdetectedin100%ofthe wild individuals, but not in captive individuals inDermatemys mawii (Rangel-Mendoza et al.,2009).HaemogregarinastepanowicanbefoundinthedistributionrangeofEuropeanturtlespeciesofthegenusEmysandMauremys(Özvegyetal.,2015;Javanbakht&Sharifi,2014).Haemosporidia (Protozoa) - detectable in blood smears; can be proof of wild origin; furthermorphological and genetic examination can determine geographic region of origin for example inTestudograecaandT.horsfieldi(Javanbaghtetal.,2015).Internalparasites:Trematodes (flukes) - Eggs detectable in feces. Require intermediate hosts, (often molluscs) that
cannotcompletelifecycleincaptivity.Cestodes(tapeworms)-Eggsandproglottidsdetectableinfeces,sometimeinorgansorabdominal
cavities (in dead specimens only), and under skin; highly suggestive for wild origin,transmissionincaptivityhighlyunlikely
Acanthocephalans(thorny-headedworms)-liveingut,eggsandlarvawithobvioushornsdetectablein feces; presence is highly suggestive of wild origin, transmission in captivity extremely

unlikely;Nematodes,particularSpirurida&Filaria (roundworms)–eggsofSpiruidainfecesandpresenceof
microscopic larvae in blood smears in Filaria suggest wild origin. Transmitted by ingestedinsectsasintermediatehostsorbyblood-suckinginsects.
Externalparasites:Ticks–presentexternallyonthespecimen,eitherattachedorunattached.Oftenrequireseveralhost
species,andwithwelldefinedgeographicalboundaries.Hyalommaaegyptiumistypical forTestudospeciesandoccursintheMediterranean,MiddleEastandCentralAsia(Briantietal.,2010);AmblyommasparsumtypicalforAfricanGeochelonespecies(Mihalca,2015).

Strong indicator as they cannot survive long incaptivity.However,maychangehost in facilitiessharedbetweenwildandcaptiveanimals.Typicalvectorofbloodparasites(hemogregarines).Ifleechesarepresentbloodshouldalsobeexamined.Presenceofbothishighlyindicative.

2. Stableisotopeanalyses:Isotopesarevariantselements,suchashydrogen,carbon,nitrogenoroxygen,thatslightlydifferbytheirmasses. Because the different isotopes vary their ratios and compositions across geographicregionsortrophiclevels,itispossibletousetheisotopesignaturesinaspecimen’stissuesampletoreconstructpastenvironmentalandclimaticconditions,itsdiet,ortrophiclevel.Isotopicanalysiscanpotentially be used as a regulatory tool for the turtle/tortoise trade such as in determining 1) ifbatchesof captive specimensalso includewild-caught individuals, and2) ifwild-caught specimenshave been fraudulently claimed as captive-bred (Wood, 2012). Isotope analysis can be of strongforensic value, highly accurate and difficult to falsify (Van Schingen et al., 2016) but is highlydependent on the reference data to compare with. At best the isotope signature of all wildpopulationsshouldbecomparedwiththesampleofunknownorigin.Toassessthevariationinthesampleswould be a first rough estimate. The isotopic variation among samples is expected to bemuch lower in captive specimens, because they always have the same food source than in wildanimals that have diverse prey. However, it is important to note that one cannot conclude thatindividuals with similar isotope signature come from the same region, only that physiologicallysimilar individualswithdifferent isotopesignatureareprobablynot fromthesamehabitat (Wood,2012;Benyr,2014).Furtherlimitationsofthemethodincludealackofestablishedprotocolsduetothe limited amount of studies conducted so far, high costs, and time expenses. Themethodmayfurther not be applicable to species with vast distribution ranges and species that are food andhabitatgeneralists(VanSchingenetal.,2016).Moreover,anumberoffactorscaninfluenceisotopesignature in an individual and lead to error, such as heat stress, age, sex, nutritional stress etc.;therefore themethod is only applicablewhendealingwith samples that are similar to samplesofunknown origin (Wood, 2012). In previous studies, isotope analysis has been used to accuratelydifferentiatewildandcaptivecrocodile lizards,Shinisauruscrocodilurus (VanSchingenetal.,2016),to reconstruct resource use over decades for the loggerhead sea turtle, Caretta caretta (VanderZandenetal.,2010),todeterminedietaryswitchesinthedeserttortoise,Gopherusagassizii(Murray&Wolf, 2012), andhas recentlybeendiscussedasa tool to regulate trade in three speciesof thegenusTestudo(Wood,2012).Howto:Tissueshavedifferentturnoverratesandthetissuetobesampleddependsonwhatbestreflectstheperiodofinterest.Tissuesthatmaybeusefulincludeclaw,carapacialandplastralkeratin,blood,andindeadspecimens:bones,liver,andmuscle(Wood,2012).Ofparticularimportanceseemstobemetabolicallyinerttissue,suchasscutematerial,whichcanbesamplednon-invasivelyandtowhichmaterialiscontinuouslyaddedoverthelifetimeinnon-sheddingspecies,becauseisotopesignaturescanbepreservedindefinitely(Wood,2012).Samplingshouldbeconductedbyaveterinarianandthesamplesofspecimenswithunknownoriginshouldbecomparedwithreferencesamplesfromwildspecimensthatshouldideallycoverthespeciesentiredistributionrange.3. Bloodparameters:Health assessmentsmeasuring haematocrit and haemoglobin concentration in blood samples andbodysizehavepreviouslybeenusedincrimeconvictionsbycomparingwildandconfiscatedanimals(Henen et al., 2013). Similar procedures might apply to captive and wild animals. For example,Swimmer(2000)foundsignificantlyhigherlevelsofcorticosterone,lactate,triglyceride,glucose,andcalciuminHawaiianwildascomparedtocaptivegreenturtles(Cheloniamydas). In loggerheadseaturtles(Carettacaretta),countofredbloodcellsandhaemoglobin levelswerehigher incaptiveascompared to wild turtles (Basilie et al., 2012). Rangel-Mendoza et al. (2009) found differencesbetween wild and captive individuals in several hematological parameters in the criticallyendangered Central American river turtle (Dermatemys mawii) and Brenner et al. (2002) in bogturtles (Clemmys muhlenbergii). Captive bog turtles had higher white blood cell counts, a lowerpercentageofheterophils,andlowerlevelsofNatrium,Kalium,andureanitrogen.Studiesinotherreptileshavefoundsimilarresults,suchasanincreaseinwhiteandredbloodcellsinwildtuatara,whichhasbeenrelatedtothehighertickburden(Cartlandetal.,1994).Obesecaptive
16
tuatara showedan increasedplasma lipid concentration, suchas cholesterol as compared to theirwild counterparts (Cartland et al., 1998). Differences in blood parameters have been mostlyattributed to differences in diet between captive and wild individuals, such as better nutritionalstatus and the richer diet of captive versuswild animals and lower protein intake inwild animals(Basilieetal.,2012).Moreover,higherdensitiesincaptivitymayresultinelevatedstresslevels,suchas corticosteroneor testosterone in somepopulations (Benyr, 2014). Bloodparameter samples ofspecimenswithunknownorigin shouldbe comparedwith reference samples fromwild specimensthat should ideally cover the species entire distribution range. Moreover, blood values may beaffectedbymany factors suchas the age, health status, themethodofbloodwithdrawal and themethodofanalysis.How to:A veterinarian can collect Blood samples. Experts for example fromveterinary orwildlifeforensics institutionsmaybeable tomake further conclusion, if reference values for thedifferentpopulationsareavailableorcanbecollected.4. Genetics:Forensic genetics is an advanced technique that can be used for species identification and sourcepopulationidentificationandmaythereforealsobeusedtoidentifywhetherananimalwascaptive-bredorwildsourced.Oneadvantageisthatitcanbeappliedtoliveorganismsbutalsotoderivativesandparts.DNA-analysiscanbeusedtodetermineifaspecimenbelongstoaCITESlistedspecies,orto assess how related is an individual to another, in this sense genetic analyses can be used todetermine the likelihood of traded specimen to in fact be the offspring from a claimed breedingstock. It isalsopossibletoassigngeneticsamplestoaparticulargeographicorigin.Likewise, itwaspossibletoassignwildandcaptiveEuropeanpondturtlestotheirregionoforiginusingthegeneticmarker cytochrome b (Velo-Anton et al., 2011). The method of identification of genetic originrequiresthatgeneticpopulationdataexistsfromthevariousregionsandthatthepopulationshavegeneticsignaturesthataresufficientlydistinctfromoneanother(Ogdenetal.,2009).Thismaynotbe the case, for example if populations regularly exchangegeneticmaterial or if populationshaveonly been recently geographically separated. Genetic data is probably still lacking for manytestudines species, but due to advances in genetic technologies they are increasingly stored ingeneticdatabasessuchasGenBank(Benson,2008).Captivepopulationsoftenshowreducedgeneticdiversityascomparedtowildpopulations,forexampleduetoinbreeding.Thismaybeusedtoassisttheidentificationofwhetheranindividualstemfromacaptivepopulation.Howto:Geneticsamplescanbecollectedbyaveterinarianforexampleasbloodortissuesamplesfromliveanimals,butaswellasfrompartsandderivativesforexamplewiththehelpofastandardDNA sampling kit. Specific Wildlife forensic DNA kits including an instruction manual have forexample been published by the ForensicWorkingGroup (FWG) part of the Partnership for ActionagainstWildlifeCrime(PAW).However,therightmolecularmarkershouldbeuseddependingonthequestions.

Desert tortoises for example reachmaturity only after 10-15years. In captivity, some speciesmay attainmaturity earlier than in thewild. The highly traded Indian startortoise(Geocheloneelegans)forexamplemayattainmaturityaround6-7yearsinthewild,butby3yearsincaptivity (D’Cruze et al. 2016). It is therefore unlikely that a facility that has recently been established sellsadultfemalesthatmaturelateproducealargenumberofoffspring.Clutchsize:Averagenumberofeggsperclutch.Testudines can have clutch sizes as little as one egg per clutch up to ~200 eggs per clutch (e.g. 75-123eggs/clutch for the Arrau turtle (Podocnemis expansa; Vanzolini, 2003); 65-193 eggs/clutch for the narrow-headed softshell turtle, (Chitra indica; Das & Singh, 2009).

Subtracting age at firstreproduction from the maximum longevity can give an upper limit on the number of years a female canreproduce (called thereproductive lifespanof thespecies).However, it is important toconsider thatnotallindividuals survive to the maximum age. In fact, these constitute only a small proportion of the totalpopulation. This is because, of the initial number of individuals being born at a given time (i.e. cohort), thenumberofindividualsstillaliveatdifferentagesdiminishesastimepasses,whichinturnreducesthenumberoffemalescapableofreproducing.Inter-birthintervals:TimebetweenconsecutivebirtheventsInmanyspecies, individualfemalesdonotreproduceeveryyear,particularlyamonglong-livedspecies.Thus,thereproductivepotentialoffemalesofaspeciesthatreproduceeverytwoyearswillbehalfofthatoffemalesofaspecieswithsameclutchsizesandreproductivelifespanbutthatreproduceeveryyear.Forexample,inawildpopulationinthewet-drytropicsofnorthernAustralia,Doodyetal.,2006,recordedthatfemalesofthePig-nosedturtles(Carettochelysinsculpta)layonlyoneeggeverysecondyear.Unfortunately, data on inter-birth intervals is not widely common, therefore it is not yet included in thedatabase.
