Many African protected areas (PAs) are not functioning effectively. We reviewed the performance of Zambia's PA network and provide insights into how their effectiveness might be improved. Zambia's PAs are under-performing in ecological, economic and

The 'two-degree field' (2dF) project at the Anglo-Australian Observatory (AAO) gives the 3.9 m Anglo-Australian telescope (AAT) a field of view two degrees in diameter at the prime focus, equipped with 400 optical fibers for multi-object spectroscopy

It is suggested that multi-mode slab waveguide spectrographs, developed for wavelength division multiplexing (WDM) in optical communications, might have a role in astronomical instrumentation. A stack of such waveguide devices could form an effective

Autofib-2 is a robotic fiber system for the prime focus of the William Herschel telescope capable of placing up to 150 fibers in the 1 degree focal plane of the telescope. The fibers are fed to a purpose built spectrograph (WYFFOS) mounted on one of

It is suggested that multimode slab waveguide spectrographs currently under development for wavelength division multiplexing in optical communications might have an application in astronomy. The nature of these devices is described, and a survey of t

The prime focus of the William Herschel telescope provides a wide field (one degree) for fiber spectroscopy. The production of the fiber feeds, which run from the prime focus to one of the Nasymyth platforms, has required the development of a multipl

We are currently testing an automated fibre positioner for the 4.2 m William Herschel Telescope (WHT). This instrument, known as Autofib-2, operates at the prime focus where it is able to utilize the full 1 degree field provided by the prime focus co

We present details of an instrumental configuration dedicated to the detection of large gas-giant planets orbiting main sequence stars via the small drop in stellar brightness that occurs when the planet transits the stellar disk. Our proposed scheme
