Detection of invasive species before or soon after they establish in novel environments is critical to prevent widespread ecological and economic impacts. Environmental DNA (eDNA) surveillance and monitoring is an approach to improve early detection efforts. Here we describe a large-scale conservation application of a quantitative polymerase chain reaction assay with a case study for surveillance...
Abiotic factors are important regulators of biological invasion and a recent study in Lake Tahoe (CA/NV, USA) showed that ultraviolet radiation (UV) can play a role in mediating warmwater fish invasion. In this study we highlight field and laboratory experiments that indicate strong species related differences in UV-induced stress between native and non-native fish species inhabiting the nearshore...
