Efforts to rid fish farms of blood-sucking aquatic lice by using chemical pesticides have ended up giving the pests increasing resistance, leading to widespread infestations in the north-eastern Atlantic Ocean.
Somewhat like ticks on land animals, salt-water-living salmon lice (
Lepeophtheirus salmonis) hook on the skin of salmonids (mainly salmon and sea trout), feeding on their blood and mucus and creating sores that can get infected and even cause death.
In natural conditions, lice numbers drop over winter as trout return to fresh water and salmon disperse into the cold ocean waters. But intense fish farming has provided the parasites abundant, year-round hosts which allow them not only to thrive in winter, but also to mutate rapidly to avoid pesticides.

The present paper is designed to investigate if Tinder usage predicts partnership development one year later on also to determine demographic, character, psychological state, and substance usage covariates when you look at the relationship between Tinder use and connection development. Information had been gathered by internet surveys (two waves) among pupils in Bergen, Norway. The very first study ended up being administered during autumn (T1). The follow-up occurred 1 later (fall, T2) year. The test consisted of this 5253 individuals whom reported become solitary at T1. The studies included questions regarding Tinder usage, demographics, character (the Five-Factor Model’s character characteristics), psychological state (for instance., signs and symptoms of despair and anxiety), liquor usage, and emp
Solar Geoengineering can Mitigate Effects of Global Warming on Rainfed Crops

Solar geoengineering, which means releasing aerosols into the air to reflect solar light and cut down global warming, is not a complete solution for climate change but it might be one of many tools to control climate risks.

The potential of solar geoengineering to decrease physical climate changes was investigated by a growing body of research. However, not much less is known about the potential effect of solar geoengineering on the ecosystem and, specifically, agriculture.
A study performed by the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has now discovered that solar geoengineering could be amazingly effective in mitigating some of the worst effects of global warming on crops.
