Data from: Coinfection with chytrid genotypes drives divergent infection dynamics reflecting regional distribution patterns
<p>By altering the abundance, diversity, and distribution of species — and their pathogens — globalization may inadvertently select for more virulent pathogens. In Brazil's Atlantic Forest, a hotspot of amphibian biodiversity, the global trade has facilitated the co-occurrence of previously isolated enzootic and panzootic lineages of the pathogenic amphibian-chytrid (<em>Batrachochytrium dendrobatidis</em>, 'Bd') and generated new virulent recombinant genotypes ('hybrid'). Epidemiological data indicate that amphibian declines are most severe in hybrid zones, suggesting that coinfections are causing more severe infections or selecting for higher virulence. We investigated how coinfections involving these genotypes shaped virulence and transmission. Overall, coinfection favored the more virulent and competitively superior panzootic genotype, despite dampening its transmission potential and overall virulence. However, for the least virulent and least competitive genotype, coinfection increased both overall virulence and transmission. Thus, by integrating experimental and epidemiological data, our results provide a mechanistic insight into how globalization can select for, and propel, the emergence of introduced hypervirulent lineages, such as the globally distributed panzootic lineage of Bd.</p>
Genotype data for: Demographic and genetic consequences of a steelhead supplementation program
<p>Supplementation of naturally-spawning populations by the addition of hatchery-spawned individuals is commonly conducted for recovery of threatened and endangered populations and to support harvest opportunities. We present an analysis of steelhead, the anadromous form of Rainbow Trout (<em>Oncorhynchus</em> <em>mykiss</em>), returning to an integrated supplemented population in Southwest Washington over the course of 15 years. The goal of the supplementation program was to evaluate whether use of a juvenile captive broodstock and an integrated paradigm could be used to increase adult returns while avoiding negative genetic impacts to the population. Estimates of relative reproductive success (RRS) for fish spawned in the hatchery ranged from 2.4 for hatchery-origin females to 6.4 for natural-origin males, indicating that fish spawned in the hatchery produced more returning adult progeny than did fish allowed to spawn in the natural environment. We observed a slight reduction in reproductive success (RS) for hatchery-origin (relative to natural-origin) fish when spawning in the natural environment, but the difference was non-significant for males and marginally significant for females. In contrast to the relatively weak relationship between RS and origin (male P = 0.347, η<sup>2</sup> = 0.008; female P = 0.066, η<sup>2</sup> = 0.037), we observed a strong relationship between RS and return year (male P < 0.001, η<sup>2</sup> = 0.896; female P < 0.001, η<sup>2</sup> = 0.867) (i.e., hatchery- and natural-origin fish did well or poorly together each year). Hatchery-origin fish exhibited reduced genetic diversity, as well as evidence of increased temporal population structure among hatchery fish. We suspect the latter is an artifact of cultural practices that reduce diversity in age at smoltification. We conclude that the program was successful in achieving an increase in adult return, but not in avoiding negative genetic effects on the population, and that any lasting impacts of supplementation remain to be determined.</p>
Genotype data of Philippine native pigs, Duroc, Landrace, Large White and Berkshire, using 20 ISAG-FAO recommended microsatellite markers
<p>Microsatellite genotyping is a cost-effective method for the genetic diversity analysis of under-studied populations, such as the Philippine native pigs. We genotyped <em>n</em> = 196 pigs representing 7 Philippine native pig populations (<em>n </em>= 20 to 27 for each population) and 4 commercial transboundary breeds (<em>n</em> = 9 to 11 for each population). Twenty microsatellite markers, recommended by the International Society of Animal Genetics (ISAG)-FAO, were used to generate the dataset for population analysis (S0005, S0155, S0026, S0355, Sw830, Sw2410, Swr1941, Sw632, Sw24, S0228, Sw936, S0097, Sw857, Sw122, Sw2406, IGF1, Sw240, S0090, S0226, Sw72). S0218 was used as a sex marker (data not shown). All loci, except Sw24, did not deviate from Hardy Weinberg equilibrium. Each marker showed an average <em>PIC </em>of 0.779. A total of 260 alleles of length 86 to 272 bp were obtained. Using this dataset, we determined population structure and conservation priorities in the Philippine native pigs. This dataset contains both the raw files (.fsa) and the processed file (.txt). This dataset can be used by colleagues to increase their research coverage and achieve multi-population and multi-country comparisons, especially among Asian indigenous pigs.</p>
