High variation in last male sperm precedence and genital morphology in the emerald damselfly, Lestes sponsa
Abstract In organisms in which individuals mate multiply, knowledge of the proportion of offspring sired by the last male to mate (P2) under field conditions is important for a thorough understanding of how sexual selection works in nature. In many insect groups, pronounced intraspecific variation in P2 is commonplace. Interestingly, however, in stark contrast to these observations, compilation of P2 data in dragonflies and damselflies (Odonata) indicates that a high P2, seldom below 0.95, is a feature of this taxon. Here we used double digest restriction-site associated DNA sequencing to generate a panel of single nucleotide polymorphisms (SNPs) with which we could determine paternity and …
The amphibian chytrid fungus Batrachochytrium dendrobatidis in Sweden
The amphibian chytrid fungus Batrachochytrium dendrobatidis in Sweden Emerging infectious disease is an important source of wildlife population declines and loss of biological diversity. Many of these emerging wildlife diseases are caused by fungi. The chytrid fungus Batrachochytrium dendrobatidis (Bd) infects amphibians and has caused severe population declines in all continents where amphibians occur. While Bd is widespread in southern and central Europe, its occurrence and distribution in northernmost Europe is unknown. Bd was first found in Sweden in 2010. To get a more complete picture of the distribution of the chytrid we conducted a larger survey during 2015 and 2016 centered round t…
