Stream bottom animals were introduced into a stream by disturbing the gravel at increasing distances upstream from drift sampler. The relationship between number of arriving sampler and distance origin was found to be N x = 0 e −RX where is introduced, R rate return animals, X maximum travelled 45.7 m mean 10.7 m. values for individual species ranged 0.0517 1.962 19.3 0.5 Specific differences could accounted in structure or behaviour animals.From these observations, model developed.

The genus Conchoecetes Stimpson, 1858, has long been considered to include three species: C. artificiosus (Fabricius, 1798), andamanicus Alcock, 1900, and intermedius Lewinsohn, 1984. type species, artificiosus, assumed be widely distributed throughout the Indo-West Pacific a fourth conchifera (Haswell, 1882), from Australia, regarded as synonym. enigmatic overlooked “Caphyra pectenicola Adams, in Belcher, 1848” is shown species of occurring Java, Singapore Gulf Thailand. We review status...
Summary Three species of duckweed, Spirodela oligorrhiza, Lemna minor and Wolffia arrhiza were grown under aseptic conditions on both buffered unbuffered solutions Jacob's media. Media with manually regulated pH levels also used. Growth media is initially rapid but eventually inhibited, probably by increased levels. On growth poor effects buffers cannot be separated out. These give inadequate pictures the species’ responses to changes in pH. most successful where sustained logarithmic...

The population biologies of Cyprinotus carolinensis, Herpetocypris reptans, Cypricercus reticulatus, and Candona decora in a spring-fed, temporary, winter puddle Vancouver, Canada, were studied during 1967–1969. All species emerged at the same time fall, when filled, competed to reach maturity. order maturation was Candona, Cyprinotus, Cypricercus, Herpetocypris. Abundance positively related adult size each species. Survivorship fecundity patterns are given for Cyprinotus. is closest type-I...
The duckweed Lemna perpusilla in a small, alkaline lake was studied during 1970 and map of its distribution prepared. Duckweed, the only floating, unrooted higher aquatic plant present, distributed around most edge but density extremely patchy. Experiments were made involving manipulation density, modification distribution, measurement factors which experiments suggested significant influences on pattern abundance. Attention particularly focused importance other plants molding pattern....
Field and laboratory observations were carried out on the reproductive behaviour of Cyclograpsus lavauxi Helice crassa, results compared with other Grapsidae, emphasis New Zealand species. Mating in all species typically occurs during intermoult often coincides time oviposition. Females several have been reported to mate multiple times, few days prior oviposition, leading sperm competition within female spermatheca. found be sexually receptive only a short period before oviposition (e.g., C....
Gandalfus puia gen. et sp. nov. (Bythograeidae) is reported from submarine volcanoes near the Kermadec Islands. The genus Austinograea revised with result that A. yunohana Takeda, Hashimoto & Ohta, 2000 transferred to new genus. Both of these species occur in relatively shallow waters (240–1650 m) compared other bythograeids. A sister group hypothesis modern genera, Allograea + (Segonzacia (Cyanagraea (Bythograea (Gandalfus Austinograea)))) presented provide an interpretation variation...
Halicarcinus cookii is a small intertidal New Zealand crab that has high levels of ovigerous females in all months. Continuous breeding requires continuous mating. Mating not linked to moulting because the pubertal moult terminal. Spermathecal fullness modelled terms difference between rates copulation and brood production. It estimated can fill their spermathecae with sperm after 3-4 copulations (depending on male size) approximately 15% an ejaculate used fertilize each brood. Given fact...
