Excerpt: Students from St Thomas Primary School discovered the small jumping Lycidas Karschi spider during a Bug Blitz field day in September. Experts have now verified the spider’s identification. “They’re a tiny little jumping spider, about 5 millimetres long,” Bug Blitz program director John Caldow said. “Children are catching things with nets and bringing them…

Editor’s Choice: One of Citizen Science’s most iconic projects, the Monarch Larva Monitoring Project, yields another excellent research result and a great lesson for all citizen science projects. By better understanding how certain species of flies impact monarch butterfly populations, researchers can better pinpoint which are human-based factors in monarch decline. — LFF — Excerpt:…

Excerpt: Phone-wielding and bare-armed, I follow Scott Edmunds and Mendel Wong to a small park in the Mid-Levels area of Hong Kong Island, where a dengue outbreak occurred last year. We hit the jackpot within five minutes – a swarm of mosquitoes around a tree. With his phone, Wong snaps a picture of one that…

Excerpt: Scientists expect Africa to be hardest hit by climate change: its dependence on agriculture, hot temperatures, and poor infrastructure mean its citizens are likely to feel the pressure of a changing climate more than most others. But there are big gaps in our knowledge of how ecosystems and microclimates work. “We don’t have an…

Abstract: The validity of the threat status assigned to a species by the International Union for Conservation of Nature’s (IUCN) Red List relies heavily on the accuracy of the geographic range size estimate for that species. Range maps used to assess threat status often contain large areas of unsuitable habitat, thereby overestimating range and underestimating…

Abstract: Changing land cover and climate regimes modify water quantity and quality in natural stream systems. In regions undergoing rapid change, it is difficult to effectively monitor and quantify these impacts at local to regional scales. In Vancouver, British Columbia, one of the most rapidly urbanizing areas in Canada, 750 measurements were taken from a…

Abstract: Despite the growing volume of available transportation data and the efforts of many cities to increase cycling levels, there remains a lack of data on where people cycle. The use of GPS trajectories have now been used in cycle studies for several years, and more recently large, crowdsourced datasets of GPS recorded cycle trips…

How can museums advance citizen science? The City Nature Challenge makes evident at least three themes: First, a belief that “science is open to all” is consistent with museums’ values of inclusivity and access. Second, museums know partnerships. (To realize this competitive bioblitz event, the California Academy of Sciences and the Natural History Museum of…

Abstract: Life history trait analyses of non-native fishes help identify how novel populations respond to different habitat typologies. Here, using electric fishing and anglers as citizen scientists, scales were collected from the invasive barbel Barbus barbus population from four reaches of the River Severn and Teme, western England. Angler samples were biased towards larger fish,…

One goal of citizen science is to encourage dissemination of citizen-made observations and knowledge gained about the interactions between the human-made and natural environments—even if that knowledge makes us uncomfortable in confronting  potentially damaging cultural traditions. Here we see something as seemingly innocent as a celebratory balloon release can have disastrous consequences. — LFF — Excerpt:…
