title: Data from: Marine protected area restricts demographic connectivity: dissimilarity in a marine environment can function as a biological barrier

description: The establishment of marine protected areas (MPAs) can often lead to
 environmental differences between MPAs and fishing zones. To determine the
 effects on marine dispersal of environmental dissimilarity between an MPA
 and fishing zone, we examined the abundance and recruitment patterns of
 two anemonefishes (Amphiprion frenatus and A. perideraion) that inhabit
 sea anemones in different management zones (i.e., an MPA and two fishing
 zones) by performing a field survey and a genetic parentage analysis. We
 found lower levels of abundance per anemone in the MPA compared to the
 fishing zones for both species (n = 1,525 anemones, p = .032). The
 parentage analysis also showed that lower numbers of fishes were recruited
 from the fishing zones and outside of the study area into each anemone in
 the MPA than into each anemone in the fishing zones (n = 1,525 anemones, p
 &lt; .017). However, the number of self-recruit production per female
 did not differ between the MPA and fishing zones (n = 384 females, p =
 .516). Because the ocean currents around the study site were unlikely to
 cause a lower settlement intensity of larvae in the MPA, the ocean
 circulation was not considered crucial to the observed abundance and
 recruitment patterns. Instead, stronger top-down control and/or a lower
 density of host anemones in the MPA were potential factors for such
 patterns. Our results highlight the importance of dissimilarity in a
 marine environment as a factor that affects connectivity.
description: Field data of
 anemonefish distributionThis file contains raw
 data collected from the field survey. In the sheet we listed: the id,
 collection date, location category (e.g., MPA, fishing zones in the
 eastern side or western side of MPA), transformed latitude, transformed
 longitude, anemonefish species name (SP), number of self-recruits produced
 at this host anemone (MSR), number of self-recruits (SR), number of
 self-recruits from the fishing zones (OSR), number of self-recruits from
 the MPA (ISR), number of immigrants (IM), total abundance of target
 anemonefish (Ab), adult abundance of target anemonefish (Adult), juvenile
 abundance of target anemonefish (Juv), host species name (Habitat; e.g.,
 EQ Entacmaea quadricolor, HC Heteractis crispa, SG Stichodactyla
 gigantea), size of host anemone (Size), presence or absence of female
 anemonefish (Female), total length of female anemonefish (F size), ,depth
 of anemone (Dep), size of each fish (Size 1~7). Latitude and longitude
 were transformed to prevent aquarium poaching.Field_Data_Sato et
 al.xlsxData of microsatellite
 genotypesThis file contains the
 genotypes for target anemonefish species (Amphiprion frenatus and A.
 perideraion). The first sheet is for A. frenatus having 14 loci and the
 second one is for A. perideraion having 15 loci. Collected anemonefishes
 from Lagindingan were categorized as a candidate mother, father or
 juvenile in the Sample ID. We also listed the collection date, GPS ID,
 location category (e.g., MPA, fishing zones in the eastern side or western
 side of MPA). The third sheet has the geographic coordinates that
 correspond to each GPS waypoint, but latitude and longitude were
 transformed to prevent aquarium poaching.Genotype_Data_Sato et
