Animalmobilityanddispersalmaybeaffectedbyhabitatloss andfragmentation(e.g.Umetsuetal.,2008;Puttkeretal.,2011), andthere isevidence ofdeleterious effectsof habitatfragmen- tationongeneticvariabilityanddifferentiationoncommonand widespreadvertebratespecieswithhighmobility(Johanssonetal., 2007;Delaneyetal.,2010;Levyetal.,2019).Landscapestructure, suchasmatrixqualityanddistanceamonghabitats,mayisolate populations,limitingtheirdispersal(Umetsuetal.,2008;Boscolo andMetzger,2011)andthus,populationconnectivityandgenetic diversity(e.g.Dixoetal.,2009;Balkenholetal.,2013;Jacksonand Fahrig,2016).

Moreover,climatechangesduringtheQuaternarymightalso haveaffectedspeciesgeneticdiversityduetothecyclesofpopu- lationexpansionandcontraction(Hewitt,2000).Populationrange contractionmaydecreaseeffectivepopulationsize,leadingtoloss ofgeneticdiversityduetogeneticdrift.Shiftsinspeciesgeographi- caldistributionsduetotheQuaternaryclimatechangeshaveplayed animportantroleinshapingthegeneticdiversityofanimalspecies intheCerradobiome(e.g.Mirandaetal.,2019).Thus,disentan- glingcontemporaryandhistoricalprocessesleadingtopopulation effectivesizereductionandlossofgeneticdiversityisimportant topredictspeciesresponsetochangesinlandscapeintheAnthro- pocene.

Batspeciesaredifferentiallyaffectedbyhabitatfragmentation (e.g. Gorresen and Willig, 2004; Meyer et al., 2009; Centeno- Cuadros et al., 2017). Some bats avoid flying over open areas (Henryetal.,2007),watercourses(Albrechtetal.,2007),androads (Zurcheretal.,2010).Thus,fragmentationhasapotentialtoiso- latebatpopulationsandreducegeneticconnectivity(Rossiteretal., 2000)andcolonizationofnewareas(KerthandPetit,2005;Russell etal.,2005).Inadditiontothebarriersimposedbythelandscape, reproductivebehaviorandhistoricalpatternsofcolonizationmay alsoberesponsibleforrestrictedgeneflow(Wilmeretal.,1999).

Althoughhighlymobile,batsmayshowdifferentdispersalpatterns andbreedingsystems,includingvariationinroostingecology,and socialstructures(McCrackenandWilkinson,2000),thatmayaffect geneticstructure(e.g.Flandersetal.,2016).Indeed,severalstud- ieshaveshownsignificantpopulationsubstructureinbatspecies atdifferentspatialscales(e.g.Biollazetal.,2010;Rippergeretal., 2013;Flandersetal.,2016).

Glossophagasoricina(Pallas1766)(Glossophaginae),thePallas’

long-tonguedbat,isoneofthemostcommonandwidespreadnec- tarivorousbatsintheNeotropics(Reisetal.,2005),andalsofeeds oninsectsandfruits(Willigetal.,1993),andusesalargevariety ofroosts(caves,trees,human-madestructures).Adultmalesmay defendharemsandjuvenilesandbothmalesandfemalesdisperse fromtheirnatalcolony(Pink,1996).Becauseofitsgeographicaldis- tributionandnaturalhistory,aloweffectofhabitatfragmentation onG.soricinageneticdiversitymaybeexpectedorevennoeffectat all.However,morethanhalfoftheCerradobiomehasbeenrapidly transformedintopasturesandcrops(Silvaetal.,2006),affecting speciesgeneticdiversityandinbreeding(e.g.Arrudaetal.,2017) jeopardizingspecieslong-termconservation.

Here,weaddresstheeffectsofcontemporarychangesinland- scapestructureand paleodistributionduringtheQuaternaryon geneticdiversityandpopulationdifferentiationinG.soricinainthe Cerradobiome.Weusedamultiscalespatialapproachtospecif- icallytestwhetherhabitatamount(forestsandsavanna),matrix (unsuitableland covers)typeand past climatechanges explain thecurrentgeneticdiversityand differentiationamongpopula- tions.Thegeneticdatawereobtainedfromnuclearbiparentally inheritedmicrosatelliteloci and thematernally inheritedmito- chondrialcytochromeBgene(CYB).Thus,usingdatafrommarkers withdifferentinheritance and evolutionaryrates ourdatamay

Materialsandmethods

Populationsandtissuessampling

We sampled 18 populations (229 individuals) of G. soricina throughout theBrazilianCerrado biome(Fig.1, TableS1). Pop- ulations were selected in landscapes with different land use composition, suchas habitat (savanna and forest)amount and matrix(unsuitablelandcover)type.Batswerecapturedwithmist netsinstalledatgroundlevelandwesampledapproximately3mm ofthewingmembrane(seedetailsinSupplementaryFileS1).

Geneticdata

Forgeneticdata,DNAwasextractedandindividualsweregeno- typedusingnine microsatelliteloci previouslydeveloped forG.

soricina(Opreaetal.,2012).Forsequencing,weusedtheprimers describedbyIrwinetal.(1991)toamplifya1140bpfragmentof thecytochrome-bmitochondrialgene(CYB).Detailsoftheproto- colsforgenotypingandsequencingaredescribedinSupplementary FileS1.

To obtain genetic parameters for microsatellite loci we estimated genetic diversity (heterozygosity expected under Hardy–Weinbergequilibrium, He),inbreedingcoefficient(f)and allelicrichnessforeachpopulation.Forpopulationgeneticdiffer- entiationweestimatedWright’sFST(Wright,1951),G’ST (Hedrick, 2005)andJost’sD(Jost,2008)usingPopGenReportpackage(Gruber andAdamack,2019)implementedinR3.6.1.(RCoreteam,2019).

WeusedaBayesianclusteringmethodimplementedinthesoft- wareStructure2.3.4(Pritchardetal.,2000),toidentifygenetically homogeneousgroupswithinoursamples.We estimateda pos- terioriprobabilityofK(numberofgroups)rangingfrom1to18 (correspondingtoeachsampledlocality).

ForCYB,weestimatednucleotide(␲)andhaplotype(h)diversity foreachpopulation,andpopulationdifferentiation(FST)usingthe softwareArlequin3.11(Excoffieretal.,2005).Populationstructure wasalsoassessedusingBayesianclusteringimplementedinthe softwareBAPSv6.0(Coranderetal.,2008)withanupperlimitofK

Ecologicalnichemodeling

Weobtained13,069occurrencerecordsofG.soricinaacrossthe Neotropics(Fig.S1).Afterdatafiltering,theremaining2353occur- rencerecords(TableS2)weremappedinagridofcellsof2.5×2.5 (longitude×latitude),encompassingtheNeotropics,togenerate thematrixofpresenceusedtocalibratetheENMs.

The climatic layers were represented by five bioclimatic variables:annualmeantemperature,meandiurnalrange,isother- mality,precipitationofwettestquarter,andprecipitationofdriest quarter,selectedbyfactorialanalysiswithVarimaxrotationfrom 19 bioclimatic variables obtained in the ecoClimate database (Lima-Ribeiro et al., 2015).Bioclimatic variables were obtained forpre-industrial(representingcurrentclimateconditions),mid- Holocene(6ka)andLastGlacialMaximum(LGM;21ka)fromfive Atmosphere-OceanGeneralCirculation Models(AOGCM) (Table S3).

Estimatesofthecurrentand pastpotentialdistributionofG.

Finally,thefullensemblewasobtainedforeach timeperiod usingthepredictiveperformances(TSS)tocomputea weighted meanofsuitabilities,fromwhichhistoricalrefugiaweremapped (i.e.allgridcellswithsuitabilityvalues≥0.5duringthethreetime periods).DetailsareprovidedinSupplementaryFileS1.

Landscapeandclimaticeffectsongeneticdifferentiation

Toperformtheanalysisatthelinklevel(WagnerandFortin, 2013), weused ResistanceGApackage(Peterman,2018), imple- mented in R 3.6.1. to optimize multiple resistance surfaces simultaneously.Forgeneticdistancematrixweusedthegenetic differentiation among all pairs of populations (Tables S6–S9):

FST (forboth microsatellites and CYB), and GST’ and Jost’ D for microsatellites.Forresistancematrixweextractedthelandcover between all pairs of populations and converted land use in resistancesurface.We alsousedtheconsensusmap of ENMat present-dayfor resistancedue toclimate, and thegeographical distancematrixtoaccountforisolation-by-distance.Optimization wasperformedwiththefunctiongdistance/commuteDistance.To selectthemostlikelymodel,weusedAICci.

We also analyzed genetic discontinuity among populations usingtheDelaunaynetwork(LegendreandLegendre,1998)imple-

mented inthe softwareSAM v.4(Rangelet al.,2010), for both microsatellitesandCYB.DetailsareprovidedinSupplementaryFile S1.

Discussion

Contemporarychangesinlandscapeandgeneticdiversity

Our findings show that contemporary changes in landscape affectsgeneticdiversityinpopulationsofGlossophagasoricinafrom theCerrradobiome.Thereplacementofnaturalvegetation,suchas forestsandsavannas,toagriculture,pasturesorurbanareasmay decreasegeneticdiversityandincreaseinbreeding.Theinfluence occursatbothspatialscalesanalyzedhere(2and5kmbuffers).

The effects of scale on therelationships betweenlandscape structureandbatoccurrence,abundanceandpopulationgenetic structurehavebeenreportedpreviously(e.g.Gorresenetal.,2005;

Razgouretal.,2014).Thelackofscaleeffectinourstudymaybedue toG.soricina’sdispersalabilityanditsforagingandmatingbehav- ior.Thehomerangeofthespeciesislargerthan2km,andthe maximumflightdistancetrackedsofarwas3.8km(Aguiaretal., 2014).However,G.soricinamakescoloniesandharemsdefended byadultmales,whichmayconstraintdispersalandcausethehigh inbreedingobserved.In addition,thedispersalconstraindueto matingbehaviormayalsoisolatecoloniesofG.soricina,explain- ingtheeffectofmatrixtypeoninbreeding.Smallerbats,suchas G.soricina,maybemoreaffectedbylandscapechangesindepen- dentofthegeographicaldistribution.Forinstance,geneticdiversity andgeneflowinCarolliacastanea,asmallwidelydistributedbat species,arenegativelyaffectedbylossofhabitat(forests)whereas thelargerArtibeusjamaicencisisnotaffectedbypercentageofforest andmatrix(Clearyetal.,2017).Likewise,Carolliaperspicillatashow lossofgeneticdiversityduetohabitatfragmentation,contrasting toUrodermabilobatum,alargermorevagilespecies(Meyeretal., 2009).

Matingbehaviorandphilopatrymayaffectpopulationstructure inbatsandincreaserelatednesswithinpopulationsandinbreeding (Biollazetal.,2010;Rippergeretal.,2013;Flandersetal.,2016).

Our findings show higher geneticdifferentiation for mitochon- drialCYBthanfornuclearmicrosatellites,whichmaybeevidence of female philopatry, i.e., malesdisperse more frequently than

(7)

females.However,itisimportanttonotethatthemitochondrial genome(mtDNA)ismaternallyinheritedwithoutrecombination andtheeffectivepopulationsizeofmtDNAissmallerthanthatof thenucleargenome,therebyleadingtoahigherrateofallelefixa- tionbygeneticdriftformtDNAthanfornuclearDNA(Birkyetal., 1983).Effectivepopulationsizemaybeoneofthemostimpor- tantfactorsinfluencingratesofmolecularevolution(Lanfearetal., 2014).Thus,differencesbetweenmicrosatellitelociandCYBmay beduetodifferencesindispersalbehaviorbutalsoinevolution- aryrates.Moreover,geneticdifferentiationatmicrosatelliteloci andCYBshoweddifferentresponsestogeographicaldistance.CYB showednoeffectofspatialdistancelikelybecausemalesdisperse morefrequentlythanfemales.

Herewefoundnoeffectoflandcoveringeneticdifferentiation atboth CYBand microsatelliteloci. However,wefounddiscon- tinuityin severalpairsofpopulations,meaningthatsomepairs ofpopulationshavehigherFST thanexpectedbytheirgeograph- icaldistance.Thegeneticdiscontinuitymaybeduetotherecent fragmentationandanthropogenicdisturbancebecausepopulations showinggeneticdiscontinuityformicrosatellitelociareimbedded inurbanareas,agricultureorpasturethatmayaffectthedispersal ofG.soricinaamonglocalities,restrictinggeneflowandincreasing inbreeding.Forinstance,population18iswithinaconservation unit,whichhaspristinevegetationandawidevariation infood resources,surroundedbyextensiveagricultureareas(mainlysoy- beanandcorn).Theregionpresentshighnumberofwell-preserved caves,whichareusedasroostsbythespecies.Allthesecharacteris- ticsmayfavorbatsstayingwithintheconservationunit,decreasing theconnectivityofthispopulation(18)evenwithpopulationsat closedistance,suchaspopulations2,3and9(seeFig.2),leadingto ageneticboundary.Infact,largerandmorestablecavesandsur- roundedbynaturalvegetationcanhavemorebatspeciesandlarger populations(e.g.Barrosetal.,2020).Population9isalsowithina conservationunit,however,withextensiveareasofsavannaand nocaves,whichmayfavorG.soricinadispersal,decreasingdiscon- tinuity.Population17issurroundedbycropsandminingindustry, whichmayisolatetheG.soricinapopulation.

Inaddition,CYBshoweddifferentpatternsofdiscontinuityand Bayesianclusteringcomparedtomicrosatelliteloci.Forinstance, population18showedhighconnectivitywithotherpopulations andnogeneticdiscontinuityforCYB.Ontheotherhand,popula- tion17hadhighdifferentiationanddiscontinuityforCYB,butnot formicrosatellites.Thisresultmaybeduetodifferentdispersal patternbetweenmalesandfemalesorduetodifferencesinevolu- tionaryrates.Microsatellitesmayshowsignalsofcurrentlandscape changeswhileCYBmayshowtheeffectsofhistoricalconnectivity andpaleodistribution(seebelow).Indeed,batsmayshowmale- biaseddispersalthatcanbehighlyaffectedbylandscapechanges andhabitatloss,leadingtolossofgeneticdiversity(Halczoketal., 2018).

Despite the high level of fragmentation and anthropogenic disturbances in the Brazilian Cerrado, the studied populations ofG.soricinapresented relativelyhighgeneticdiversity atboth microsatellitelociandCYB,similartothelevelsofotherPhyllosto- midaebatssuchasLophostomasilviculum(He=0.490;Dechmann etal.,2002),Carolliabrevicauda(Herangingfrom0.430to0.940;

Bardelebenetal.,2007)andDermanurawatsoni(hrangingfrom 0.902to0.991,andnumberofhaplotypesrangingfrom11to21;

Rippergeretal.,2013).Ourresultsalsoshowlowbutsignificantdif- ferentiationformicrosatelliteloci(FST =0.056,P<0.0001)among populationsofG.soricinaintheBrazilianCerrado,similartoother bat species,such asPlecotus auritus(FST ranging from0.011to 0.026;BurlandandWilmer,2001)andNyctalusazoreum(FSTrang- ingfrom0.009to0.036;Salgueiroetal.,2008;).Thelowgenetic differentiationamongpopulationsmaybetheoutcomeofhistorical long-distancedispersal.Infact,Bayesianclusteringshowedthree

geneticgroupsindicatingweakgeneticstructureamongsiteswith highlevelsofgeneflow.Theonlyexceptionwaspopulation18, whichshowedhighandsignificantvaluesofpairwiseFST forall comparisons.

Paleodistributiondynamicsaffectedgeneticboundariesbetween populations

Wefoundnoevidencethatpaleodistributionchangesduring theQuaternarysignificantlyaffectedthegeneticparametersana- lyzed.Thelackofsignificanteffectmaybeduetothequasistability ofG.soricina’sgeographicalrangesincetheLGM.Infact,ourfind- ingsshowaslightlylargergeographicalrangeduringtheLGMthan atthemid-Holoceneorpresent-day,showingthatG.soricinamay haveexpanded itsdistributionduringtheglacialperiodsof the Quaternary,whenseasonally dryforestsandopenedvegetation expandedtheirdistributions(Penningtonetal.,2000).

Nevertheless, thelarge areasof high suitabilitythrough the Quaternarymayhave beenhistoricalclimaticrefugia,maintain- ing populationsthroughtime. The historical refugiaprovided a sourceofmigrantstocolonizenewsuitableareaswhilethespecies wastrackingclimaticniche.ENMshowedthatseveralpopulations ofG.soricina inCentral Brazilwereoutside theclimaticrefugia (seeFig.3)fromtheLGMtopresent-day,explainingthegenetic discontinuityat CYB betweensome populations,suchas popu- lation17.Ontheotherhand,somepopulationswereconnected inthepast,suchaspopulation18,andcontemporarylandscape changes mayhave isolated populations leadingto low connec- tivity and genetic discontinuityat microsatelliteloci. Thus, the geneticboundariesamongpopulationsmaybedue toboth, the paleodistributiondynamicsintheQuaternary,andthecontempo- rarylandscapechanges.

Concludingremarks
