Temporal changes in genetic variability in three bumblebee species from Rio Grande do Sul, South Brazil

摘要: In order to protect biodiversity, conservation genetics are of great importance. Until now, a few population genetic studies Neotropical bumblebees available but temporal stability in diversity lacking. Here, variability three South Brazilian species Bombus bellicosus, B. pauloensis, and morio was investigated over time. Hereto, museum collection specimens 1946 until 2012, from eight locations Rio Grande do Sul, were genotyped at 16 microsatellite loci. During an additional sampling the foraging season 2015, no could be collected possibly due super El Nino 2015–2016. Our results on demonstrated significantly higher than pauloensis. Genetic pauloensis gradually decreased time 2012; while morio, remained stable last period (2010–2012). For not enough data available. Although studied populations became more vulnerable time, for bumblebees, still information is needed include frequent monitoring bumblebees. Adding bellicosus list threatened suggested.
