Workers in colonies of European honey bees Apis mellifera L. clean their
nestmate's body by allogrooming behavior. This behavior may be initiated by
either grooming dancers or by the allogroomers themselves. The first occurs
less frequently (ca. 17 %) than the later (83 %). By using the inner edge of...
Juvenile T. townsendii were tested at 55-62 days of
age to determine whether 1) they could distinguish kin from
non-kin and 2) whether this ability was based on
familiarity or on genetic relatedness. Seventy-three pups
were observed in 68 pairwise tests. The frequencies and
durations of 8 behaviors as well...
Population attributes, behavior, and activity patterns of
Nuttall's cottontails (Sylvilagus nuttallii) inhabiting a
juniper-sagebrush scabland community in central Oregon were studied
between June 1980 and August 1981. Cottontails were trapped, marked
for individual recognition, and released at their sites of capture.
Data collected by periodic trapping and censusing of cottontails...
Across much of North America, legacies of historic and contemporary timber harvest have created a landscape dominated by regenerating forest stands in the early to middle stages of development. Most streamside forests are currently in the stem-exclusion phase of stand development and these closed canopies shade the forest understory and...
Traditional interpretations of James Joyce's Dubliners have often focused on the pervasive "paralysis" of the city, covered in the stories' range of "childhood, adolescence, maturity, and public life." However, these approaches have limited their focus on the women in the stories, often spotlighting the male characters--and the author--through a Freudian...
Riparian zones are ecotones between terrestrial and aquatic ecosystems. Processes in streams are strongly influenced by riparian forest communities, age, stage and structure. Temperate forests across much of North America, including riparian areas, are recovering from historic land clearing with many stands in the stem-exclusion phase of development in which...
During the development of the media for the identification and
differentiation of Clostridium perfringens and C. botulinum types A,
B and E, 16 different double layer media were prepared and tested
with known cultures of 28 C. botulinum strains, 20 C. perfringens
strains and 11 other clostridial species.
The semisolid...
The 105,000 x g supernatant fluid (S[subscript HS]) from extracts of pea seedlings
(Pisum sativum, var. Alaska) etiolated for 60 hours yielded a
very potent adenosine triphosphatase activity. This activity was designated
as an apyrase when the reaction stoichiometry indicated that
adenosine triphosphate (ATP) was hydrolyzed to adenosine monophosphate
(AMP)...
