Wake Atoll: Evaluation of plant biosecurity
Full text linkIntroduced organisms can cause substantial effects across most landscapes. Island ecosystems, especially tropical islands, are at elevated risk from introduced organisms. The risks are even higher for tropical islands with moderate or high levels of transit, yet this can be minimized by application of appropriate biosecurity requirements. In this study, we examined the potential for non-native plant species introductions, especially invasive plants, via shipping containers to be transported to Wake Atoll, one of the most remote terrestrial land masses in the Pacific Ocean. We sowed debris collected from 30 shipping containers in a greenhouse experiment to determine if any live plants could be germinated, identify any species that germinated, and ascertain if they posed a threat if they were to be transported to Wake Atoll and became established there. During this study 23 plant species were identified, including ferns, monocots, and dicots. Fifteen of these species reached reproductive maturity over the course of seven months. From previous plant surveys on the atoll, we know that 13 of the 23 identified species were not previously recorded, and four species are already known to be invasive on Wake Atoll. This study provides insight into the potential for debris found in shipping containers to contribute to the spread of non-native, possibly invasive species. This information may help with the refinement of biosecurity strategies to prevent the accidental introduction of invasive species into sensitive natural areas such as Wake Atoll

Improving efficiency of disease vector sampling in the field: An automatic solar-powered mosquito trapping system
Full text linkTrapping mosquitoes to quantify their distribution and abundance is often a key step in monitoring dynamics of vector-borne diseases. This is the case in Hawaii, where avian malaria is devastating native forest birds that are highly susceptible to non-native diseases. However, mosquito trapping is difficult and labor intensive. A typical operation requires traps to be visited multiple times within a 24-hour period to control their active components and batteries. For example, traps for nocturnal mosquitoes require trap fans and carbon dioxide (CO2) tanks turned on in the evening and then turned off the following morning, with batteries changed frequently. For traps in very remote locations, this frequent attendance accrues considerable cost and personnel time. To help minimize field efforts required for maintaining mosquito trapping arrays, we developed an automated power system to operate the mosquito traps. The traps can be set to operate on a schedule using a built-in timer, eliminating the need for personnel to manually turn traps on and off. Additionally, this system is powered by a solar-recharged battery so that the system can run indefinitely in many field locations. We tested the system at ‘Āinahou Ranch in Hawai‘i Volcanoes National Park, Island of Hawai‘i, where we operated a trapping array continuously for over two years. Specifically, two types of traps were deployed at each location, one a gravid trap and another a CO2 trap. We provide a step-by-step guide on how to build the systems and describe how to deploy them in the field
