The implications of insectsÕ vision for territorial defense have been relatively little studied in the Þeld. In the dragonßy Perithemis tenera Say we investigated whether either the angle at which an intruder was viewed by a territorial resident or the background against which it was viewed affected the detection of that intruder. Residents detected intruders at a greater distance if the intrud...
How mechanical and biological processes are coordinated across cells, tissues, and organs to produce complex traits is a key question in biology. Cardamine hirsuta, a relative of Arabidopsis thaliana, uses an explosive mechanism to disperse its seeds. We show that this trait evolved through morphomechanical innovations at different spatial scales. At the organ scale, tension within the fruit wa...
Seventeen exclosures were built by the New Zealand Forest Service within Urewera forests over the period 1961-68 to exclude ungulates. Forest structure and species composition inside and outside these exclosures were compared in 1980-81. Some relatively shade tolerant species such as the fern Asplenium bulbiferum, the liane Ripogonum scandens, the sub-canopy shrubs Geniostoma ligustrifolium and...
The genus Porphyra comprises red algae known as laver. They are distributed throughout Asia and used as food in Korea and other countries. Five species of Porphyra (P. tenera, P. yezoensis, P. seriata, P. suborbiculata and P. dentata) are regarded as ecologically and economically important in Korea. We used random amplified polymorphic DNA (RAPD) to investigate their genetic diversity and phylo...
