Episode 95: Becoming Bat with Angelica Caiza Villegas
No full textIn this episode of Knowing Animals I am joined by Angelica Caiza Villegas. Angelica is a PhD student in the Department of Cultural Geography at the University of Groningen in the Netherlands. We discuss her paper titled ‘Becoming Bat: Bats, Bat-lovers and Bat-detectors’ which is currently under review with the journal Social & Cultural Geography. Her co-author is Bettina van Hoven

Food and foraging behaviour of bat-eared foxes in the south-eastern Orange Free State
No full textOtocyon megalotis feed on a wide variety of insect taxa and other prey items. Harvester termites Hodotermes mossambicus form a major component of the prey, and increase in importance during winter. Individual foxes consume 1.15 × 106 termites/yr. Taking into account mean group size and home range size, 40 500 termites/ha/yr are eaten by foxes. When feeding on termites, concentrated in patches, bat-eared foxes feed c70% of their foraging time, as against feeding 4% of their foraging time when eating singly occurring prey. -from Author
Smoking in Ghana: a review of tobacco industry activity.
No full textBACKGROUND: African countries are a major potential market for the tobacco industry, and the smoking epidemic is at various stages of evolution across the continent. Ghana is an African country with a low prevalence of smoking despite an active tobacco industry presence for over 50 years. This study explores potential reasons for this apparent lack of industry success. OBJECTIVE: To explore the history of tobacco industry activity in Ghana and to identify potential reasons for the current low prevalence of smoking. METHODS: A search was made of tobacco industry archives and other local sources to obtain data relevant to marketing and consumption of tobacco in Ghana. FINDINGS: British American Tobacco, and latterly the International Tobacco Company and its successor the Meridian Tobacco Company, have been manufacturing cigarettes in Ghana since 1954. After an initial sales boom in the two decades after independence in 1957, the sustained further increases in consumption typical of the tobacco epidemic in most countries did not occur. Possible key reasons include the taking of tobacco companies into state ownership and a lack of foreign exchange to fund tobacco leaf importation in the 1970s, both of which may have inhibited growth at a key stage of development, and the introduction of an advertising ban in 1982. BAT ceased manufacturing cigarettes in Ghana in 2006. CONCLUSION: The tobacco industry has been active in Ghana for over 50 years but with variable success. The combination of an early advertising ban and periods of unfavourable economic conditions, which may have restricted industry growth, are likely to have contributed to the sustained low levels of tobacco consumption in Ghana to date

Assessing changes in bat activity in response to an acoustic deterrent: implications for decreasing bat fatalities at wind facilities
No full textWind energy is a renewable resource with many environmental benefits. However, one environmental impact from wind energy is on bats, because bats are killed when they fly into the path of spinning turbine blades. Estimates of bat fatalities at wind facilities across the U.S. exceed 500,000 per year. One potential way to reduce bat fatalities at wind facilities is with acoustic deterrents. These devices, including the newly designed acoustic deterrent tested during this study, produce sound to deter bats. At a wind farm in north-central Texas, we assessed changes in bat activity at wind turbines and closely associated cattle ponds in response to the acoustic deterrent. The acoustic deterrent reduced the level of bat activity by up to 90%, indicating it has the potential to reduce bat fatalities when installed on wind turbines
ROBAT: Experimental investigation of a bat inspired robotic wing
No full textThe research done on bat flight has increased the knowledge about bat flight and the corresponding aerodynamic phenomena in great extent. In the mid seventies and eighties, the first kinematic studies by Norberg (1976a,b) and Aldridge (1986, 1987) were performed with the use of high speed cameras and made it possible to analyze the kinematics of bat flight in great detail. These studies were first performed in _ight corridors, later followed by measurements in windtunnels (Busse von, 2011). This made it possible to measure over a range of flight speeds, which shows a gradual change in kinematics when _ight speed is increased. Aerodynamic measurements were the next step in bat flight research and gave a better insight in the vortex structure of bat _ight both onwing (Muijres et al., 2008) and in the wake (Hedenstrom et al., 2007, 2009; Johansson et al., 2008).Aerospace Engineerin
