ONE FLUE OVER THE SWALLOW'S NEST

forestry.gov.uk Thankful county foresters were glad to forego firing up their new ‘green’ flue for fear of frying their feathered friends. The Forestry Commission team were about to ignite their new environmentally friendly heating system when an eagle-eyed ornithologist called a dramatic halt. RSBP volunteer Juliette Buttler was on duty at the foresters’ Fineshade base, […]

Distribution of Neuraminidase in Arthrobacter and Its Purification by Affinity Chromatography1

jb.oxfordjournals.org Yoshihiro UCHIDA, Yoji TSUKADA and Tsunetake SUGIMORI Kyoto Research Laboratories, Marukin Shoyu Co., Ltd. Uji, Kyoto 611 Neuraminidase [sialidase, EC 3.2.1.18 [EC] ] was found to be widely distributed in bacteria belonging to Arthrobacter. Among these bacteria, Arthrobacter ureafaciens, A. oxydans, and A. aurescens produced relatively potent neuraminidase activities. For the production of this […]

THE POTENTIAL OF FARMING EDIBLE-NEST SWIFTLETS IN SABAH

sabah.gov.my Laurentius N. Ambu Deputy Director Sabah Wildlife Department Kota Kinabalu ABSTRACT The two most economically-important swiflets are the so-called edible nest swiflets: the white-nest swiflets (Aerodramus fuciphagus) and the Black-nest swiflet (Aerodramus maximus). Both species occur in Sabah. With the dwindling edible-nest swiflets population due to effects of increased harvesting pressure and effects of […]

Knowledge and Utilization of Edible Mushrooms by Local Populations of the Rain Forest of South Cameroon

bioone.org Han van Dijk, Neree Awana Onguene, Thomas W. Kuyper Indigenous knowledge of edible fungi and their utilization by local populations were investigated in southern Cameroon from 1996 to 1999. Some 100 participants from the major ethnic groups, comprising Bantu farmers and Bagyeli (Pygmy) hunter-gatherers, were interviewed. Mushroom usage by 30 families, (319 persons), was […]

Ornithology :Avian Reproduction: Nests

An updated version of these notes can be accessed from a new “Avian Biology’ page (http://people.eku.edu/ritchisong/avian_biology.html).   Birds use nests to protect eggs and nestlings from predators and adverse weather. To minimize predation, birds may use or build nests that are inaccessible, hidden, or camouflaged. Nests may also help keep eggs and nestlings warm. Orientation […]

HINESBURG — Four young ravens, glossy black and big as chickens, listened curiously as University of Vermont zoologist Bernd Heinrich called them. Old enough to fly but not old enough to fend for themselves, the birds looked warily at Heinrich through the open door of their aviary. He waved a bite-sized chunk of veal at them.

Nest spacing in relation to settlement time in colonial cliff swallows.

ncbi.nlm.nih.gov • Brown CR, • Brown MB. Department of Biological Sciences, University of Tulsa How colonial animals space their nests in relation to conspecifics may provide clues as to whether coloniality provides net benefits or occurs only because breeding sites are limited. We examined how nearest-neighbour distance varied in relation to settlement time in the […]
