Data from: Low temperature reveals genetic variability against male-killing Spiroplasma in Drosophila melanogaster natural populations

Iuri Matteuzzo Ventura, Thais Costa & Louis Bernard Klaczko
Spiroplasma endosymbionts are maternally inherited microorganisms which infect many arthropod species. In some Drosophila species, it acts as a reproductive manipulator, spreading in populations by killing the sons of infected mothers. Distinct Drosophila melanogaster populations from Brazil exhibit variable male-killing Spiroplasma prevalences. In this study, we investigated the presence of variability for the male-killing phenotype among Drosophila and/or Spiroplasma strains and verified if it correlates with the endosymbiont prevalence in natural populations. For that, we...

Data from: Metapopulation dynamics of the mistletoe and its host in savanna areas with different fire occurrence

Grazielle Sales Teodoro, Eduardo Van Den Berg & Rafael Arruda
Mistletoes are aerial hemiparasitic plants which occupy patches of favorable habitat (host trees) surrounded by unfavorable habitat and may be possibly modeled as a metapopulation. A metapopulation is defined as a subdivided population that persists due to the balance between colonization and extinction in discrete habitat patches. Our aim was to evaluate the dynamics of the mistletoe Psittacanthus robustus and its host Vochysia thyrsoidea in three Brazilian savanna areas using a metapopulation approach. We also...
