The strength and arrangement of movement barriers can impact the
connectivity among habitat patches. Anthropogenic barriers (e.g. roads)
are a source of habitat fragmentation that can disrupt these resource
networks and can have an influence on the spatial genetic structure of
populations. Using microsatellite data, we evaluated whether observed
genetic structure of moose (Alces alces) populations were associated with
human activities (e.g. roads) in the urban habitat of Anchorage and rural
habitat on the Kenai Peninsula, Alaska. We found evidence of a recent
genetic subdivision among moose in Anchorage that corresponds to a major
highway and associated infrastructure. This subdivision is most likely due
to restrictions in gene flow due to alterations to the highway (e.g.
moose-resistant fencing with one-way gates) and a significant increase in
traffic volume over the past 30 years; genetic subdivision was not
detected on the Kenai Peninsula in an area not bisected by a major
highway. This study illustrates that anthropogenic barriers can
substructure wildlife populations within a few generations and highlights
the value of genetic assessments to determine the effects on connectivity
among habitat patches in conjunction with behavioral and ecological data.
Genotypic data and spatial coordinates of female moose in AlaskaThis file
contains genotype data from ten microsatellites and spatial coordinates of
female moose from two populations in south-central Alaska (Anchorage and
Kenai Peninsula Game Management Unit 15C). Individuals are also indicated
whether they were part of a telemetry/movement study (collared) from which
annual home range size was estimated or if sample was obtained from a
hunter. This file was used for to generate infiles for genetic structure
analyses in Geneland and R package adegent
(sPCA).Genotypic_data_and_spatial_ coordinates_Alaska_Moose.xlsxGeneland
infilesThis zipped folder contains the infiles for used for the program
Geneland. The spatial coordinate file is in UTMs (zone 6 for Anchorage and
zone 5 for Kenai Peninsula Game Management Unit 15C).sPCA infilesThis
zipped folder contains the infiles (genepop and coordinate files) for used
for the sPCA analysis in the R package adegenet.
