Utah Lake Sediment Core Data
<p>Files contain data collected from sediment core archives from 4 locations of Utah Lake, Utah.</p> <p>Core locations include Goshen Bay, Provo Bay, Bird Island, and North. Provo Bay cores were collected in both 2018, but due to poor chronology new cores were collected at an alternate location in 2020. The 2020 Provo Bay cores had satisfactory chronologies. </p> <p>Data include initial core descriptions (ICD), carbon and nitrogen mass and isotopes, geochemistry, diatom, pigments, and rock-eval pyrolysis. </p> <p>Publications (Journal articles, theses, and white papers) include all methods, data, and interpretations and should be cited along side the Zenodo data citation. </p>

SW Gulf of Mexico planktonic foraminifera, oxygen isotopes and Mg/Ca data from core RC10-265PC spanning MIS 6 to MIS 1
<p>In the sediment Core RC10-265PC collected in the oligotrophic region of the SW Gulf of Mexico, it was reconstructed the surface ocean conditions, including water masses, the mixed layer depth and the sea surface temperatures over the Late Pleistocene to Holocene (last 180 cal ka BP). This database includes (Table S1) the counting and distribution of planktonic foraminifera assemblages, and (Table S2) stable oxygen isotopes (δ<sup>18</sup>O-PDB) (‰) of <em>Globigerinoides ruber</em> (white) and elemental ratios of Mg/Ca (mmol/mol), Mn/Ca (mmol/mol), Fe/Ca (mmol/mol), Sr/Ca (mmol/mol), Mn/Fe (mmol/mol).</p>
Data from: Ex situ conservation of underutilised fruit tree species: establishment of a core collection for Ficus carica L. using microsatellite markers (SSRs)
Ex situ germ plasm collections of woody crops are necessary to ensure the optimal use of plant genetic resources. The fig tree (Ficus carica L.) germ plasm bank, consisting of 229 accessions, is located in Centro de Investigación 'La Orden'. Despite great progress in conservation, ex situ collections face size and organization problems. Core collections obtained from structured samples of bigger collections are a useful tool to improve germ plasm management. In this work, we used simple sequence repeat (SSR) markers to establish a core collection in this underutilised Mediterranean fruit tree species. Four approaches have been carried out (random sampling, maximization, simulated annealing and stepwise clustering) to determine the best method to develop a core collection in this woody plant. The genetic diversity obtained with each subset was compared with that of the complete collection. It was found that the most efficient way to achieve the maximum diversity was the maximization strategy, which, with 30 accessions, recovers all the SSR alleles and does not show significant differences in allele frequency distribution in any of the loci or in the variability parameters (H O, H E) between the whole and core collections. Thus, this core collection, a representative of most fig diversity conserved in the germ plasm bank, could be used as a basis for plant material exchange among researchers and breeders.
Data from: History matters more when explaining genetic diversity within the context of the core-periphery hypothesis
The core–periphery hypothesis (CPH) predicts that populations located at the periphery of a species' range should have lower levels of genetic variation than those at the centre of the range. However, most of the research on the CPH focuses on geographic distance and not on ecological distance, or uses categorical definitions of core and periphery to explain the distribution of genetic diversity. We use current climate data and historical climate data from the last glacial maxima to develop quantitative estimates of contemporary and historical ecological suitability using ecological niche models. We analysed genetic diversity using 12 polymorphic microsatellites to estimate changes in heterozygosity, allelic richness and population differentiation in 31 populations of the wood frog (Lithobates sylvaticus) spanning the species' entire eastern clade (33o to 45o latitude) from Alabama, USA, to Nova Scotia, Canada. Our data support predictions based on the CPH. Populations showed significant differences in genetic diversity across the range, with lower levels of genetic variation at the geographic range edge and in areas with lower levels of historical and contemporary ecological suitability. However, history and geography (not current ecological suitability) best explain the patterns. This study highlights the importance of examining more than just geography when assessing the CPH, and the importance of historical ecological suitability in the maintenance of genetic diversity and population differentiation.
Data from: Genetic population structure of the blister beetle Gnathium minimum: core and peripheral populations
Populations on the periphery of a species' range tend to contain lower genetic variation and increased genetic differentiation compared to populations at the core of a species range, although some exceptions to this generalization occur. The blister beetle Gnathium minimum (Say) exhibits a wide-ranging distribution in the western United States but has peripheral or disjunct populations in Mexico, Florida, and Wisconsin. We used amplified fragment length polymorphism (AFLP) to compare the genetic variation and magnitude of genetic differentiation of the Wisconsin peripheral population to western core populations (Colorado, Kansas, New Mexico, and Texas). The proportion of polymorphic loci was 53.6 and 54.3, and expected heterozygosity 0.1864 and 0.1933 for the Kansas/Colorado (n = 87) and New Mexico/Texas (n = 35) regions, respectively. Specimens from Wisconsin (n = 121) had a lower proportion of polymorphic loci (38.4) and expected heterozygosity (0.1475). Genetic cluster estimation with GENELAND and F ST values showed greater genetic differentiation among the sampling locations within Wisconsin compared to core regions. Significant isolation-by-distance (IBD) was also observed in Wisconsin but not within the core regions. Lower genetic variation and increased isolation may reduce the Wisconsin population's ability to respond to change, thereby increasing their susceptibility to extinction.
