BACKGROUND AND AIMS Gesneriaceae is a pantropical plant family with over 3000 species. A great variety of pollination mechanisms have been reported for the neotropical members of the family, but the details of buzz-pollination and enantiostyly for the family have not been described. We investigated the floral biology and pollination ecology of Paraboea rufescens in Xishuangbanna, south-west Chi...

Elephantulus rufescens is one of 15 species of elephant-shrews (F. Macroscelididae), a specialized group of mammals confined to the continent of Africa (see Rathbun, 1979, for review). Since elephant-shrews have only recently been successfully bred in captivity (Rathbun, Beaman & Maliniak, 1981), information on their reproduction has largely been obtained from examination of the reproductive or...

Cryptomonads are ubiquitous aquatic unicellular eukaryotes that acquired photosynthesis through the uptake and retention of a red algal endosymbiont. The nuclear genome of the red alga persists in a highly reduced form termed a nucleomorph. The nucleomorph genome of the model cryptomonad Guillardia theta has been completely sequenced and is a mere 551 kilobases (kb) in size, spread over three c...

In flow tank experiments, I tested the relative importance of active and passive processes to larvae settling on manufactured casts that were hydrodynamically rough at a small scale (mm to <1 cm). I predefined two distinct regions of small-scale flow that I used to manipulate larval settlement behaviour of the red abalone Haliotis rufescens Swainson. The larvae show a stringent settlement respo...

In this paper, we describe Endocarpon subramulosum as a new species from temperate regions of South Korea, which grows over soil on rocks. The proposed new species is morphologically similar to E. ramulosum Harada, which has so far been reported from Japan.

Further to anatomical and physiological studies performed on the pika (Ochotona rufescens rufescens), a new laboratory animal, the main characteristics of the mitochondrial DNA from its liver are defined. The buoyant density of this DNA is 1.695 g/cm3, its length 5.30 mum,, i.e., 3.17 times that of the replicative form of phiX 174. It could have approximately 16 500 base pairs. The DNA from the...
