(1) One type of short-axon horizontal cell (HC) and one type of axonless HC are described in the retina of Carinae noctua, a crepuscular bird and Tyto alba, a pure nocturnal bird.
(2) Yet it is ever more dissected by hacks and bloggers who pretend to be heretical but are just gossip merchants who never question the deep structures of governance and merely legitimate their own crepuscular existence.
(3) "Late" like the autumnal, musical Eliot of Four Quartets; like the demanding, crepuscular Beethoven quartet the film's characters rehearse for their silver-anniversary performance (String Quartet No 14 in C sharp minor – menacingly referred to as "Op 131"); and "late" in the connected senses of former or dead, which this quarrelsome foursome soon might be if they fail to recover their harmony.
(4) To describe his work in progress, he jotted down a list of hyperbolic adjectives: "Astounding, extraordinary, surprising, superhuman, supernatural, unheard of, savage, sinister, formidable, gigantic, savage, colossal, monstrous, deformed, disturbed, electrifying, lugubrious, funereal, hideous, terrifying, shadowy, mysterious, fantastic, nocturnal, crepuscular."
(5) Hourly sampling with human bait showed a bimodal pattern, with a greater peak in the evening crepuscular period.
(6) Malaise-trapped females showed a distinct crepuscular peak of host-seeking activity.
(7) Whereas in humans the retinal sampling frequency approaches the optical cut-off frequency quite closely, in diurnal insects of both types the image is undersampled by a factor of 2-3, and in crepuscular spiders this factor may be greater than 100.
(8) Paranoid reaction may get closer to hysterical crepuscular states.
(9) Longterm castrates (under LD 8:16) displaying either predominantly diurnal or crepuscular activity were implanted with either empty Silastic capsules or capsules containing testosterone.
(10) Errol Morris , a respected documentarian himself and one of the film's executive producers (along with Werner Herzog ), defended the film on the grounds that "by re-enacting the murders … [we] could become reconnected to a history that had nearly vanished into a crepuscular past."
(11) The superposition eye of the cockchafer, Melolontha melolontha, exhibits the typical features of many nocturnal and crepuscular scarabaeid beetles: the dioptric apparatus of each ommatidium consists of a thick corneal lens with a strong inner convexity attached to a crystalline cone, that is surrounded by two primary and 9-11 secondary pigment cells.
(12) We found that the gerbil in captivity, unlike most rodents that are nocturnal, is a crepuscular animal, being more active at the transitions between light and dark.
(13) Repellency was determined during a 2 h crepuscular period using volunteers who had been treated with repellents 6, 8, 10, and 12 h prior to the end of each test period.
(14) Biting occurred during the day with early morning and late afternoon peaks and continued into the crepuscular period.
(15) Castrates showed a trend toward increased crepuscular preference.
(16) The present experiments were designed to examine the effects of various durations of day- and night-time exposures to low intensity (1.0 gauss rms) 60 Hz magnetic fields on light (L) and dark (D) period opioid-mediated aversive thermal ('nociceptive') responses and morphine-induced 'analgesia' in the nocturnally-crepuscularly active land snail, Cepaea nemoralis.
(17) Green sunfish actively avoided temperatures exceeding 30.3 degrees C and below 26.5 degrees C and had a median preferred temperature of 28.2 degrees C. Temperature preference did not vary significantly during the diel period even though locomotory activity patterns were markedly crepuscular.
(18) The effects of various durations (0.5, 2, 12, 48, or 120 h) of day- and night-time exposures to a 1.0 gauss (rms) 60-Hz magnetic field or sham field on mortality levels in the nocturnally-crepuscularly active land snail, Cepaea nemoralis, were examined.
(19) In relation to the vespertine crepuscular period, precrepuscular peaks were observed in the highland area.
(20) Animals with testosterone implants displayed increased preference for nocturnal and decreased preference for crepuscular activity as compared to controls.
