Ethiopia harbours several relict populations of African wild dogs Lycaon pictus, but most data is anecdotal. Wild dogs are known to occur atypically in the montane wet forest of Harenna in the southern slopes of Bale Mountains National Park, southeastern Ethiopia. A questionnaire-survey of 90 Harenna forest residents investigated the local people’s knowledge and attitudes to wild dogs. Wild dog...

Reliable knowledge of the status and trend of carnivore populations is critical to their conservation and management. Methods for monitoring carnivores, however, are challenging to conduct across large spatial scales. In the Northern Rocky Mountains, wildlife managers need a timeand costefficient method for monitoring gray wolf (Canis lupus) populations. Montana Fish, Wildlife and Parks (MFWP) ...

A total of 32 individuals of a chaetodontid fish resembling Prognathodes guezei (Mauge & Bauchot) were recorded on photographs and videotape taken from the Hawaii Undersea Research Laboratory's deep-sea submersibles Makali'i and Pisces-V between 1982 and 1990. These sightings represent the first record of the genus Prognathodes from the Hawaiian Islands. The fish were observed at depths of 106-...

The waitoreke, or supposed South Island otter, has remained a mystery for over a century; for, despite the authoritative evidence of Haast' (1877, 1879), some highly circumstantial early Maori accounts and numerous well-documented' and impressive claims of later sightings by' amateur naturalists, zoologists generally have been only too happy to dismiss the animal as a myth. An examination of mu...

Field experiments were performed to examine the effect of adult diet on calling activity, female attraction, and mating success in male Mediterranean fruit flies, Ceratitis capitata (Wiedemann). In all tests, comparisons were drawn between males fed sugar only (“proteindeprived” males) and males fed a protein-sugar mixture (“protein-fed” males). In tests of long-distance attraction, aggregation...

The Orange-necked Partridge, Arborophila davidi, is limited to small fragmented patches in southern Vietnam and a small adjacent area in Cambodia. It was first discovered at Bu Kroai, Binh Phuoc Province, Vietnam, but not observed again by scientists until three sightings in 1991 on a small isolated hill at c.150–200 m near Dak Lua substation, Cat Tien National Park (Dong Nai and Lam Dong provi...

These sightings are useful to researchers and managers only ifthe data can be efficiently acquired, stored and retrieved for analysis.· We identified several problems in the wildlife sightings reporting system at Lassen Volcanic National Park, including a confusing ar...

82 AI MAGAZINE Akey feature of an autonomous system, here onwards referred to as an agent (Russell and Norvig 2010), is the capability to choose optimally between different lines of action available to it. This capability of normative decision making becomes demanding in diverse informational and physical contexts, which may range from having precise information about all aspects of the problem...

Previous studies of mouse allergens and laboratory-animal-worker-related allergy and asthma suggest that quantifying mouse allergen levels in homes could augment our understanding of inner-city asthma. We hypothesized that levels of mouse allergen in inner-city homes would be related to certain household characteristics. Dust samples were collected from the kitchens and beds of 221 mothers enro...

Whale sharks, Rhincodon typus, are often perceived as solitary behemoths that live and feed in the open ocean. To the contrary, evidence is accumulating that they are gregarious and form seasonal aggregations in some coastal waters. One such aggregation occurs annually north of Cabo Catoche, off Isla Holbox on the Yucatán Peninsula of Mexico. Here we report a second, much denser aggregation of ...
