A single panmictic population of endemic red crabs, Gecarcoidea natalis, on Christmas Island with high levels of genetic diversity
The red crab, Gecarcoidea natalis, is endemic to Christmas Island in the Indian Ocean and largely responsible for sha** the unique ecosystem found throughout the island’s rainforests. However, the introduction ...

Wetlands as landscape units: spatial patterns in salinity and water chemistry
Athalassic wetlands play a pivotal role in sediment and nutrient cycling and retention at the catchment level and are important ecosystems for local and regional biodiversity. Yet, the management of wetlands o...

Benthic Metabolism as an Indicator of Stream Ecosystem Health
We tested direct and indirect measures of benthic metabolism as indicators of stream ecosystem health across a known agricultural land-use disturbance gradient in southeast Queensland, Australia. Gross primary...

An experimental examination of female preference patterns for components of the male advertisement call in the quacking frog, Crinia georgiana
Even though females prefer particular components of a male display, their preferences may not be expressed during mate choice. Here, we quantified female preference patterns in the frog Crinia georgiana for call ...

Call structure may affect male mating success in the quacking frog Crinia georgiana (Anura: Myobatrachidae)
We investigated the relationship between mating success, male size and variation in the advertisement call in the frog Crinia georgiana under field conditions. Mating success in 91 males was determined by followi...

Highly Variable Microsatellites in the California Market Squid Loligo opalescens
Attempts to study the genetic population structure of cephalopods are impeded by the low levels of genetic variation in these species. We have developed polymerase chain reaction (PCR) primers for six hyperva...

The phylogeny of echinoderm classes based on mitochondrial gene arrangements
Previous analyses have demonstrated that, among the echinoderms, the sea star (class: Asteroidea) mitochondrial genome contains a large inversion in comparison to the mitochondrial DNA of sea urchins (class: E...

Nucleotide sequence of nine protein-coding genes and 22 tRNAs in the mitochondrial DNA of the sea starPisaster ochraceus
We have cloned and sequenced over 9 kb of the mitochondrial genome from the sea starPisaster ochraceus. Within a continuous 8.0-kb fragment are located the genes for NADH dehydrogenase subunits 1, 2, 3, and 4L (N...

Multiple interactions in juxtaposed monolayers of amphibian neuronal, epidermal, and mesodermal limb blastema cells
We have utilized a novel cell culture system to probe nerve-epidermal-blastema cell interactions, in which the cellular participants are plated as compartmentalized juxtaposed monolayers. A mesoderm monolayer ...

Conserved tRNA gene cluster in starfish mitochondrial DNA
Partial sequencing of mtDNA from four long-diverged species of starfish reveals the existence of a conserved cluster of 13 tRNA genes, organized in a manner similar to that of the tRNA cluster of sea urchin mt...
