In another experiment, the researchers showed that training did not help participants to detect morphs
presented onscreen, and detection rates remained around the chance level.
Construction of computer-animated courtship displays.--Face-on computer-animated stimuli (CAS): Face-on CAS were constructed by digitizing raw video footage of courting males of T and G morphs
in phase I courtship display (see Clark & Uetz 1990, 1992, 1993 for details on constructing and appropriately sizing video stimuli).
These sounds, a car alarm (SoundJay.com) or a loud buzzer (SoundBible.com), were chosen because actual predator calls used in the other trials might have elicited a ceiling effect, masking real differences between morphs
in terms of their boldness.
cordata were visited by several species of hymenopterans, butterflies, flies and birds (Wolfe & Barrett 1988) whose preferences in collecting pollen or feeding on nectar among the floral morphs
differed (Wolfe & Barrett 1987, 1989; Harder & Barrett 1993; Orth & Waddington 1997), even though the amount of nectar produced did not differ between morphs
(Wolfe & Barrett 1987).
Under the hypothesis of background matching by morphs
, we expected to find different predation rates under a variety of pattern-background combinations.
Frequency of colour morphs
relative to ant assemblages
Table 1 summarizes the mean body dimensions and morphometric ratios for the two wing morphs
after those individuals that had an E/C ratio smaller than the above criteria were categorized as short-winged morphs
Named after the little clay TV friend of the late Tony Hart, the Morphs
, when off-duty, are a group of teenage boys allied to Northumberland Youth Service and Doxford Youth Project in Seaton Delaval, where Emma Rudd, of the youth service, works with them at Astley Community High School.
Summary: A flash mob of tiny Morph
figures has been held to honour TV artist Tony Hart who died earlier this year.
Each one was formed in the shape of children's television favourite Morph
TRIBE: The Morphs
outside the Tate Modern, and below, their creator the artist Tony Hart
So for example in the 'link' section you click on 'link' which morphs
slowly into 'greg lynn form' and when you click on that you get back to the home page.
